Property descriptions

DesktopMoviePlayer.Active

Active As Boolean

Indicates whether the control is active.

This property is read-only.

Active is False when the control's window is not in the foreground. When a DesktopWindow is deactivated, its controls are automatically deactivated unless AllowAutoDeactivate is set to False.

DesktopMoviePlayer.AllowAutoDeactivate

AllowAutoDeactivate As Boolean

Determines whether the control should be deactivated (on macOS) when the parent window is deactivated. The default is True.

DesktopMoviePlayer.AllowTabStop

AllowTabStop As Boolean

If True, the control is in the Tab Order and accepts the focus when the user tabs into it. The default is True. If False, the user cannot tab into it to give it the focus. However, the control can gain the focus by other means, such as the user's clicking on it or by setting the focus in code.

This example removes the control from the Tab Order:

Me.AllowTabStop = False

DesktopMoviePlayer.AutoAdjustToMovieSize

AutoAdjustToMovieSize As Boolean

If True, the DesktopMoviePlayer control resizes itself to fit the size of the movie. The default is True.

Because movie loading is asynchronous, you should not have AutoAdjustToMovieSize = True if you are also manually modifying the Width and Height as it is possible that the auto resizing will occur after you have changed the size.

This example turns off AutoAdjustToMovieSize.

Var f As FolderItem
f = FolderItem.ShowOpenFileDialog(FileTypes1.VideoMp4)
If f <> Nil Then
  MoviePlayer1.AutoAdjustToMovieSize = False
  MoviePlayer1.Movie = Movie.Open(f)
End If

DesktopMoviePlayer.AutoPlay

AutoPlay As Boolean

If True, the movie will start playing automatically when it is assigned to the Movie property of the control. The default is False.

This example sets AutoPlay and then opens a movie.

Var myMovieFile As FolderItem

myMovieFile = FolderItem.ShowOpenFileDialog(FileTypes1.VideoMp4)
If myMovieFile <> Nil Then
  MoviePlayer1.AutoPlay = True
  MoviePlayer1.Movie = Movie.Open(myMovieFile)
End If

DesktopMoviePlayer.AutoRepeat

AutoRepeat As Boolean

If True, it replays the movie automatically when it reaches the end. The default is True.

This example turns AutoRepeat off.

Var f As FolderItem

f = FolderItem.ShowOpenFileDialog(FileTypes1.VideoMp4)
If f <> Nil Then
  MoviePlayer1.AutoPlay = True
  MoviePlayer1.AutoRepeat = False
  MoviePlayer1.Movie = Movie.Open(f)
End If

DesktopMoviePlayer.ControllerHeight

ControllerHeight As Integer

The height of the controller (pixels).

This property is read-only.

DesktopMoviePlayer.ControllerWidth

ControllerWidth As Integer

The width of the controller (pixels).

This property is read-only.

DesktopMoviePlayer.Duration

Duration As Double

The duration (in seconds) of the currently playing media.

This property is read-only.

The movie must be playing for this property to hold a value. If no movie is playing, it is set equal to zero.

This example gets the Duration of the movie.

Var duration As Double = MoviePlayer1.Duration

DesktopMoviePlayer.Enabled

Enabled As Boolean

Determines if the control should be enabled when the owning window is opened.

A disabled control cannot be clicked and cannot receive the focus.

This example disables the control.

Me.Enabled = False

DesktopMoviePlayer.Handle

Handle As Ptr

Returns a handle to the control.

This property is read-only.

For interfacing with Mac APIs using Declares, DesktopControl.Handle returns NSViews (except for DesktopToolbar).

On Windows returns the HWND of the control.

On Linux it returns a GtkWidget.

The following gets a handle to the control.

Var p As Ptr = Me.Handle

DesktopMoviePlayer.HasBorder

HasBorder As Boolean

Indicates whether or not it is visible.

DesktopMoviePlayer.HasController

HasController As Boolean

Determines if the controller is displayed. The default is True.

This example hides the controls and autoplays the movie.

Var f As FolderItem

f = FolderItem.ShowOpenFileDialog(FileTypes1.VideoMp4)
If f <> Nil Then
  MoviePlayer1.AutoPlay = True
  MoviePlayer1.HasController = False
  MoviePlayer1.Movie = Movie.Open(f)
End If

DesktopMoviePlayer.HasStepControls

HasStepControls As Boolean

If True, the controller has forward and reverse arrows to the right of the slider. The default is True.

When set in code, HasStepControls takes effect the next time the MoviePlayer is assigned a movie.

This example hides the step controls. Since it is called prior to the assignment of a movie to the player, the controls are not shown for this movie.

Var f As FolderItem

f=FolderItem.ShowOpenFileDialog(FileTypes1.VideoMp4)
If f <> Nil Then
  MoviePlayer1.AutoPlay = True
  MoviePlayer1.HasStepControls = False
  MoviePlayer1.Movie = Movie.Open(f)
End If

DesktopMoviePlayer.HasVolumeControl

HasVolumeControl As Boolean

Displays the speaker volume control.

When set in code, this takes effect the next time the DesktopMoviePlayer control is assigned a movie.

The following example hides the volume control before assigning a movie to the player.

Var f As FolderItem

f = FolderItem.ShowOpenFileDialog(FileTypes1.VideoMp4)
If f <> Nil Then
  MoviePlayer1.AutoPlay = True
  MoviePlayer1.HasVolumeControl = False
  MoviePlayer1.Movie = Movie.Open(f)
End If

DesktopMoviePlayer.Height

Height As Integer

The height (in points) of the control.

This example sets the height of the control to 100:

Me.Height = 100

DesktopMoviePlayer.Index

Index As Integer

If the control is used in a control set, this specifies the control's index in the set.

This property is read-only.

DesktopMoviePlayer.Left

Left As Integer

The distance from the left side of the control to the left side of its containing window or container.

The following example moves the control 100 points from the left side of the window:

Me.Left = 150

DesktopMoviePlayer.LockBottom

LockBottom As Boolean

Determines whether the bottom edge of the control should stay at a set distance from the bottom edge of the parent control, if there is one, or the owning window.

This property can be set in the control's Inspector. The following example sets it in code.

Me.LockBottom = True

DesktopMoviePlayer.LockLeft

LockLeft As Boolean

Determines whether the left edge of the control should stay at a set distance from the left edge of the parent control, if there is one, or the owning window.

LockLeft and Locktop default to True when you add a new control to a window. Existing controls will be altered only if LockRight and/or LockBottom are not set. LockLeft has no effect unless LockRight is True.

This property can be set in the control's Inspector. The following example sets it in code.

Me.LockLeft = True

DesktopMoviePlayer.LockRight

LockRight As Boolean

Determines whether the right edge of the control should stay at a set distance from the right edge of the parent control, if there is one, or the owning window.

This property can be set in the control's Inspector. The following example sets it in code.

Me.LockRight = True

DesktopMoviePlayer.LockTop

LockTop As Boolean

Determines whether the top edge of the control should stay at a set distance from the top edge of the parent control, if there is one, or the owning window.

LockTop and LockLeft default to True when you add a control to a window. Existing controls will be altered only if LockRight and/or LockBottom are not set. LockTop has no effect unless LockBottom is True.

This property can be set in the control's Inspector. The following example sets it in code.

Me.LockTop = True

DesktopMoviePlayer.MouseCursor

MouseCursor As MouseCursor

The cursor to be displayed while the mouse is within the control and both the DesktopApplication and DesktopWindow class's MouseCursor properties are Nil.

If the DesktopApplication class's MouseCursor property is not Nil or the DesktopWindow's MouseCursor property is not Nil, then any control's MouseCursor property is ignored. You can use a cursor stored in the Cursors module. On Macintosh, you can also obtain a MouseCursor from a resource file.

This line in the Opening event of the control sets the default cursor to the finger pointer.

Me.MouseCursor = System.Cursors.FingerPointer

DesktopMoviePlayer.Movie

Movie As Movie

The movie that will be played.

This example displays a movie in a DesktopMoviePlayer and plays it.

Var f As FolderItem

f = FolderItem.ShowOpenFileDialog(FileTypes1.VideoMp4)
If f <> Nil Then
  MoviePlayer1.AutoPlay = True
  MoviePlayer1.Movie = Movie.Open(f)
End If

DesktopMoviePlayer.Name

Name As String

The name of the control. Set the name of the control in the Inspector.

This property is read-only.

DesktopMoviePlayer.OLEMovieObject

OLEMovieObject As OLEObject

Returns an OLEObject that you can use to access the DesktopMoviePlayer directly. Documentation for this object can be found here: https://msdn.microsoft.com/en-us/library/windows/desktop/dd563945(v=vs.85).aspx

This property is read-only.

Sets the "stretchToFit" property in the OLEObject to True:

Var obj As OLEObject = MoviePlayer1.OLEMovieObject
obj.Value("stretchToFit") = True

DesktopMoviePlayer.PanelIndex

PanelIndex As Integer

If the control has been placed on a DesktopTabPanel or DesktopPagePanel control, this is the panel (page/tab) that the control is on. If the control is not on a panel, it returns -1.

The first panel is numbered zero. If the control has been placed on a panel of a DesktopTabPanel or DesktopPagePanel control, it returns the panel number. If the control is not on a DesktopPagePanel or DesktopTabPanel, it returns -1. If you change the PanelIndex to a nonexistent panel, the control will disappear until you give it a PanelIndex value that corresponds to a panel that exists.

If you are looking to change the currently selected panel (page/tab), use DesktopPagePanel.SelectedPanelIndex.

This code displays the panel index of the control that is on the page.

MessageBox(Me.SelectedPanelIndex.ToString)

DesktopMoviePlayer.Parent

Parent As Object

Used to get and set the control's parent control or window.

If the control is on the window, the Parent will be the Window. If the control is on the container, the Parent will be the container. If the control is completed enclosed by another control, the Parent will be that control.

If you do not want the enclosing control to be the parent, set the Parent property of that control to Nil to make it the Window.

If the parent control is somehow in another window, an InvalidParentException will occur.

The following example sets the parent of the control to the window.

Me.Parent = Nil

DesktopMoviePlayer.Position

Position As Double

The number of seconds from the start of the movie.

The following example moves the playhead to the 60 second point in the movie.

MoviePlayer1.Position = 60

DesktopMoviePlayer.RepeatInReverse

RepeatInReverse As Boolean

If True, it plays the movie in reverse when the movie reaches its end. AutoRepeat must be True for RepeatInReverse to work.

The following example invokes the RepeatInReverse feature.

Var f As FolderItem

f = FolderItem.ShowOpenFileDialog(FileTypes1.VideoMp4)
If f <> Nil Then
  MoviePlayer1.AutoPlay = True
  MoviePlayer1.RepeatInReverse = False
  MoviePlayer1.Movie = Movie.Open(f)
End If

DesktopMoviePlayer.Scope

Scope As Integer

Used to determine whether access to the control is Public (0) or Private (2). The default is Public.

This property is read-only.

Note

This is a designtime-only property and thus can only be set in the Inspector and is not accessible via code.

If the Scope of a control is set to Private, it cannot be accessed from outside its parent window.

DesktopMoviePlayer.TabIndex

TabIndex As Integer

The control's position in the Tab Order. The control with whose TabIndex is 0 will get the focus first.

On macOS, only controls where you enter data from the keyboard typically get the focus. In order to manually set focus to controls that don't allow keyboard entry, go to System Preferences, click on the Keyboard icon then on the Shortcuts tab and then check the Use keyboard navigation to move focus between controls checkbox.

This example sets the control's TabIndex.

Me.TabIndex = 2

DesktopMoviePlayer.Tooltip

Tooltip As String

Text of help message displayed as a Windows or Linux "tooltip" or macOS help tag.

The tip/tag is displayed when the user hovers the mouse cursor over the control.

This example adds a tooltip to a control:

Me.Tooltip = "Click to bark."

DesktopMoviePlayer.Top

Top As Integer

The distance from the top of the control to the top of its containing window or container.

This example sets the top of the control to 140 points from the top of the window:

Me.Top = 140

DesktopMoviePlayer.Transparent

Transparent As Boolean

Determines whether the control is transparent on Windows. The default is False. Has no effect on macOS or Linux.

Transparent controls draw more slowly and use more memory in order to cache the background. Unless you absolutely require transparency, leave this set to False.

For projects that were created prior to 2018r1, this property defaults to True to emulate previous behavior. Consider changing it to False to improve performance if you do not require transparency.

DesktopMoviePlayer.Visible

Visible As Boolean

Determines whether the control is visible when its owning window is opened. The default is True: the control is visible.

The following code makes the control invisible:

Me.Visible = False

DesktopMoviePlayer.Volume

Volume As Integer

Gets or sets the movie's volume. The range is from 0 to 255.

This example sets the volume to a very low level.

MoviePlayer1.Volume = 10

DesktopMoviePlayer.Width

Width As Integer

The width (in points) of the control.

The following example resizes the control:

Me.Width = 200

DesktopMoviePlayer.Window

Window As DesktopWindow

The control's parent window.

This property is read-only.

This code gets the parent window's Title property.

MessageBox(Me.Window.Title)

Method descriptions

DesktopMoviePlayer.AcceptFileDrop

AcceptFileDrop(FileType As String)

Permits documents of type FileType to be dropped on the control. FileType must be a file type that you defined in via the FileType class or the File Type Sets Editor.

This code in the Opening event makes it possible for the user to drop either a picture or a file that is a jpeg image. The File Type Sets editor was used to define the “image/jpeg” file type. It is one of the “Common File Types” that is available in the editor.

Me.AcceptPictureDrop
Me.AcceptFileDrop("image/jpeg")

To restrict file drops to just folders (and not files), you can put this code in the DragEnter event:

If Not obj.FolderItem.IsFolder Then Return True

DesktopMoviePlayer.AcceptPictureDrop

AcceptPictureDrop

Permits pictures to be dropped on the control.

If a control should accept pictures in a drag and drop, then AcceptPictureDrop needs to be called prior to the drop. Typically, it is in the Opening event of the control itself. For example, the line:

Me.AcceptPictureDrop

in the Opening event of the control that will receive the dragged pictures is needed. When the picture is dropped, the DropObject event is called and this is where you will put your code to handle the drop.

Opening Event:

Me.AcceptPictureDrop

DropObject Event:

If obj.PictureAvailable Then
  Me.Backdrop = obj.Picture
End If

DesktopMoviePlayer.AcceptRawDataDrop

AcceptRawDataDrop(Type As String)

Permits data (of the Type specified) to be dropped on the control.

The following specfies a generic file type defined in the File Type Sets editor.

Me.AcceptRawDataDrop("????")

DesktopMoviePlayer.AcceptTextDrop

AcceptTextDrop

Permits text to be dropped on the control.

This line in the Opening event of a control that can accept dragged text.

Me.AcceptTextDrop

DesktopMoviePlayer.Close

Close

Closes a control.

Closing a control permanently removes the control from memory, making it impossible to access. You can close both non-indexed controls and indexed controls. When you close an indexed control, the indexes for the remaining controls will shift downward so that the indexes start with zero and are consecutive.

The following code closes the control. When this is executed from a visible control, the control disappears from the window.

Me.Close

DesktopMoviePlayer.DrawInto

DrawInto(g As Graphics, x As Integer, y As Integer)

Draws the contents of the control into the specified Graphics context. The parameters x and y are the coordinates of the top, left corner.

Note

DrawInto will only work if the control is on a window or container.

This example draws the current control into the Graphics of a Picture and then displays it as the Backdrop of a Canvas:

Var p As New Picture(Me.Width, Me.Height)
Me.DrawInto(p.Graphics, 0, 0)
Canvas1.Backdrop = p

DesktopMoviePlayer.Play

Play

Plays the current movie.

The following example opens the movie that the user chose and plays it.

Var f As FolderItem

f = FolderItem.ShowOpenFileDialog(FileTypes1.VideoMp4)
If f <> Nil Then
  MoviePlayer1.RepeatInReverse = False
  MoviePlayer1.Movie = Movie.Open(f)
  MoviePlayer1.Play
End If

DesktopMoviePlayer.Refresh

Refresh(immediately As Boolean = False)

Redraws the portion specified of the contents of the control the next time the OS redraws the control or immediately if True is passed.

If you are calling this so frequently that you experience a slowdown in your code, pass True for the immediately parameter.

Calling this method causes the Render event to fire.

Refresh the entire area immediately:

Me.Refresh(True)

DesktopMoviePlayer.Refresh

Refresh(x As Integer, y As Integer, width As Integer, height As Integer, immediately As Boolean = False)

Redraws the portion specified of the contents of the control the next time the OS redraws the control or immediately if True is passed.

Refresh a portion of the area the next time the OS redraws the control:

Me.Refresh(100, 150, 200, 300)

DesktopMoviePlayer.SetFocus

SetFocus

If applicable, sets the focus to the DesktopUIControl. KeyDown events are directed to the control.

If the control cannot get the focus on the platform on which the application is running, SetFocus does nothing. The SetFocus method of the DesktopWindow class or the ClearFocus method can be used to remove the focus from the control that currently has the focus, leaving no control with the focus.

Note

On the Mac you need Full Keyboard Access turned on in System Preferences (Keyboard->Shortcuts) in order to manually set focus to non-text controls.

The following example in the Opening event sets the focus to the that control. If another control has the focus when this line is executed, then the user sees this control gets the focus.

Me.SetFocus

DesktopMoviePlayer.Stop

Stop

Stops the current movie.

This example stops the current movie that is playing in MoviePlayer1.

MoviePlayer1.Stop

Event descriptions

DesktopMoviePlayer.Closing

Closing

The control is closing.

DesktopMoviePlayer.ConstructContextualMenu

ConstructContextualMenu(Base As DesktopMenuItem, x As Integer, y As Integer) As Boolean

This event is called when it is appropriate to display a contextual menu for the control.

This event handler is the recommended way to handle contextual menus because this event figures out whether the user has requested the contextual menu, regardless of how they did it. Depending on platform, it might be in the MouseUp or MouseDown event and it might be a right+click or by pressing the contextual menu key on the keyboard, for example.

Base is analogous to the menu bar for the contextual menu. Any items you add to Base will be shown as menu items. If you return False, the event is passed up the parent hierarchy.

If you return True, the contextual menu is displayed. The parameters x and y are the mouse locations. If the event was fired because of a non-mouse event, then x and y are both set to -1. See the example of a contextual menu in the following section.

The following ConstructContextualMenu event handler builds a menu with three menu items plus a submenu with three additional menu items.

' Add some items
base.AddMenu(New DesktopMenuItem("Test 1"))
base.AddMenu(New DesktopMenuItem("Test 2"))
base.AddMenu(New DesktopMenuItem("Test 3"))

' Add a Separator
base.AddMenu(New DesktopMenuItem(DesktopMenuItem.TextSeparator))

' Add a sub menu
Var submenu As New DesktopMenuItem("SubMenu")
submenu.AddMenu(New DesktopMenuItem("SubMenu Test 1"))
submenu.AddMenu(New DesktopMenuItem("SubMenu Test 2"))
submenu.AddMenu(New DesktopMenuItem("SubMenu Test 3"))
base.AddMenu(submenu)

' Add a Separator
base.AddMenu(New DesktopMenuItem(DesktopMenuItem.TextSeparator))

Return True

DesktopMoviePlayer.ContextualMenuItemSelected

ContextualMenuItemSelected(HitItem As DesktopMenuItem) As Boolean

Fires when a contextual menuitem selectedItem was selected but the MenuItemSelected event and the MenuHandler for the DesktopMenuItem did not handle the menu selection.

This event gives you a chance to handle the menu selection by inspecting the menuitem's Text or Tag properties to see which item was selected. Use this in conjunction with ConstructContextualMenu if you have not specified the MenuItemSelected event or the Menu Handler for the items on the contextual menu. See the example of a contextual menu in the examples for the DesktopUIControl class.

Return True if this event has handled the item the user chose from the contextual menu. Returning False will cause the control's parent to execute its ContextualMenuAction event. This can be handy if you have the same contextual menu for several controls who share the same Parent (several on the same window for example). By returning False you can handle them all in a single event.

This simple event handler displays the value of the selected menu item.

If selectedItem <> Nil Then MessageBox(selectedItem.Text)
Return True

DesktopMoviePlayer.ControllerSizeChanged

ControllerSizeChanged

The size of the controller has changed.

When a movie first starts this event fires and allows you read the ControllerWidth/Height properties and then resize the MoviePlayer and or window to best accommodate that size. The event also fires if the movie changes size "on its own."

DesktopMoviePlayer.DragEnter

DragEnter(obj As DragItem, Action As DragItem.Types) As Boolean

Fires when the passed DragItem enters the DesktopUIControl.

Returns a Boolean. Return True from this event to prevent the drop from occurring.

The Action parameter specifies the type of drag action.

To restrict file drops to just folders (and not files), you can put this code in the DragEnter event:

If Not obj.FolderItem.IsFolder Then Return True

DesktopMoviePlayer.DragExit

DragExit(obj As DragItem, Action As DragItem.Types)

Fires when the passed DragItem exits the DesktopUIControl.

The Obj parameter is the item being dragged. The Action parameter specifies the type of drag action.

DesktopMoviePlayer.DragOver

DragOver(x As Integer, y As Integer, obj As DragItem, Action As DragItem.Types) As Boolean

Fires when the DragItem is over the DesktopUIControl.

The Obj parameter is the object being dragged. The coordinates x and y are relative to the DesktopUIControl. Returns a Boolean. Return True from this event to prevent the drop from occurring.

The Action parameter specifies the type of drag action, which is typically done by holding down a modifier key (Shift, Alt, Option, Command, etc.) while doing the drag.

DesktopMoviePlayer.DropObject

DropObject(Obj As DragItem Action As DragItem.Types)

The item represented by Obj has been dropped on the control.

The Obj parameter is the object being dragged. The Action parameter specifies the type of drag action.

The following DropObject event handler can handle either a dropped picture or a dropped file. The type of file that it can handle needs to have been specified in a call to AcceptFileDrop prior to the drop, for example, in the Opening event.

If Obj.PictureAvailable Then
  Me.Image = obj.Picture
ElseIf Obj.FolderItemAvailable Then
  Me.Image = Picture.Open(obj.FolderItem)
End If

DesktopMoviePlayer.FocusLost

FocusLost

The control has lost the focus.

Note

On macOS, controls other than text fields and lists will accept and lose focus only if the full keyboard access option is enabled in System Preferences/Keyboard.

DesktopMoviePlayer.FocusReceived

FocusReceived

The control has received the focus and has a selection rectangle around it.

Note

On macOS, controls other than text fields and lists will accept focus only if the full keyboard access option is enabled in System Preferences/Keyboard.

DesktopMoviePlayer.KeyDown

KeyDown(Key As String) As Boolean

The user has pressed the Key passed while the control has the focus.

Returning True prevents the KeyDown event on the parent control (usually the window) from executing. Returning False results in the execution of the KeyDown event of the parent control.

DesktopMoviePlayer.KeyUp

KeyUp(Key As String)

Fires when the passed Key is released in the control that has the focus.

It is not guaranteed to be the same key that received the KeyDown event.

DesktopMoviePlayer.MouseDown

MouseDown(X As Integer, Y As Integer) As Boolean

The mouse button was pressed inside the control's region at the location passed in to x, y.

This event fires repeatedly while the mouse button is being held down.

The coordinates x and y are local to the control, i.e. they represent the position of the mouse click relative to the upper-left corner or the control.

Return True if you are going to handle the MouseDown. In such a case:

  • The Pressed event, if any, will not execute and the state of the object will not change.

  • You will receive the MouseUp event.

If you return False, the system handles the MouseDown so the MouseUp event handler do not get called.

The MouseDown event uses the DragItem constructor when the user drags the contents of the control. It is:

Var d As DragItem
d = New DragItem(Self, Me.Left, Me.Top, Me.Width, Me.Height)
d.Picture = Me.Image
d.Drag ' Allow the drag

DesktopMoviePlayer.MouseDrag

MouseDrag(X As Integer, Y As Integer)

The mouse button was pressed inside the control and moved (dragged) at the location local to the control passed in to x, y.

This event fires repeatedly while the mouse button is down regardless of whether or not the mouse coordinates are changing.

This event will not occur unless you return True in the MouseDown event.

DesktopMoviePlayer.MouseEnter

MouseEnter

The mouse has entered the area of the control.

DesktopMoviePlayer.MouseExit

MouseExit

The mouse has left the area of the control.

DesktopMoviePlayer.MouseMove

MouseMove(X As Integer, Y As Integer)

The mouse has moved within the control to the coordinates passed. The coordinates are local to the control, not to the window.

DesktopMoviePlayer.MouseUp

MouseUp(X As Integer, Y As Integer)

The mouse button was released. Use the x and y parameters to determine if the mouse button was released within the control's boundaries.

Note

This event will not occur unless you return True in the MouseDown event. The return value is ignored.

The parameters x and y are local coordinates, i.e. they represent the position of the mouse click relative to the upper-left corner or the control. Mouse clicks that are released to the left or above a control are negative.

DesktopMoviePlayer.MouseWheel

MouseWheel(X As Integer, Y As Integer, DeltaX As Integer, DeltaY As Integer) As Boolean

The mouse wheel has been moved.

The parameters X and Y are the mouse coordinates relative to the control that has received the event. The parameters DeltaX and DeltaY hold the number of scroll lines the wheel has been moved horizontally and vertically, as defined by the operating system. DeltaX is positive when the user scrolls right and negative when scrolling to the left. DeltaY is positive when the user scrolls down and negative when scrolling up.

Returns a Boolean. Return True to prevent the event from propagating further.

DesktopMoviePlayer.MovieStarted

MovieStarted

The current movie has started playing.

DesktopMoviePlayer.MovieStopped

MovieStopped

The current movie has stopped playing.

DesktopMoviePlayer.Opening

Opening

The control is about to be displayed. Use this event to initialize a control.

The Opening event is called after the Constructor.

Be warned that initializing control property values using the Constructor instead of the Opening event may result in those property values being overwritten by what is set in the Inspector. For best results, use the Opening event for control initialization rather than the control Constructor.

If the control is supposed to handle drag and drop, you need to tell it which type of item it needs to be able to handle. The following example informs the control that pictures and files can be dropped on it. The type of the file it needs to support is specified via the File Types Editor.

Sub Opening()
  Me.AcceptPictureDrop
  Me.AcceptFileDrop("JPEG")
End Sub

Notes

Windows uses the Windows Movie Player to play movies and macOS uses AVFoundation. On Linux, the MoviePlayer uses GStreamer by default (it requires version 0,10+) and uses Xine if GStreamer is not available.

The HasController property dictates if the movie controls (if any) will be displayed. Passing False means that there will be no user controls available. Passing True means that the regular movie controls will be available.

Because movie loading is asynchronous, you should not have AutoAdjustToMovieSize = True if you are also manually modifying the Width and Height as it is possible that the auto resizing will occur after you have changed the size.

Windows resizing

Movies do not automatically resize to fill the screen on Windows. You can alter this behavior with this code:

Var obj As OLEObject = MoviePlayer1.MovieController
obj.Value("stretchToFit") = True

Sample code

This code sets the movie "myHomeMovie" as the movie to be played.

MoviePlayer1.Movie = myHomeMovie

This code loads a movie called "MyMovie" from the current folder into MoviePlayer1 and plays it.

Var f As FolderItem
f = FolderItem.ShowOpenFileDialog("MyMovie")
MoviePlayer1.HasVolumeControl = True
MoviePlayer1.HasStepControls = False
MoviePlayer1.Movie = Movie.Open(f)
MoviePlayer1.Play

If you added the movie to your project, you can assign it to the movie property with only one line of code:

MoviePlayer1.Movie = MyMovie

The following code uses the OLEMovieObject property to get the current position of the player:

Var pos As Double
pos = MoviePlayer1.OLEMovieObject.Controls.CurrentPosition

Compatibility

Desktop projects on all supported operating systems.
