Method Detail

dragEnter

public TransferMode dragEnter(java.lang.Object e)

Description copied from interface: com.sun.javafx.tk.TKDropTargetListener

Called during a drag gesture, when the mouse pointer enters the operable part of the Scene.

Specified by:

dragEnter in interface com.sun.javafx.tk.TKDropTargetListener

Parameters:

e - a drop target drag event

Returns:

transfer mode chosen by potential target

dragOver

public TransferMode dragOver(java.lang.Object e)

Description copied from interface: com.sun.javafx.tk.TKDropTargetListener

Called during a drag gesture, while the mouse pointer is still over (is moving over) the operable part of the Sceme.

Specified by:

dragOver in interface com.sun.javafx.tk.TKDropTargetListener

Parameters:

e - a drop target drag event

Returns:

transfer mode chosen by potential target

dropActionChanged

public void dropActionChanged(java.lang.Object e)

Description copied from interface: com.sun.javafx.tk.TKDropTargetListener

Called if the user has modified the intended TransferMode of the drag gesture. This usually happens as a result of different keys being pressed/released during the gesture (alt, shift, ctrl, etc.)

Specified by:

dropActionChanged in interface com.sun.javafx.tk.TKDropTargetListener

Parameters:

e - a drop target drag event

dragExit

public void dragExit(java.lang.Object e)

Description copied from interface: com.sun.javafx.tk.TKDropTargetListener

Called during a drag gesture, when the mouse pointer exits the operable part of the Scene.

Specified by:

dragExit in interface com.sun.javafx.tk.TKDropTargetListener

Parameters:

e - a drop target drag event

drop

public TransferMode drop(java.lang.Object e)

Description copied from interface: com.sun.javafx.tk.TKDropTargetListener

Called when the drag gesture is being terminated with a drop on the operable part Scene.
This method is responsible for undertaking the transfer of the data associated with the gesture. The dropTargetDropEvent provides a means to obtain an object that represents the data object(s) to be transfered.
From this method, the implemenation needs to allow {javafx.scene.transfer.DragEvent#accept()} or {javafx.scene.transfer.DragEvent#reject()} to be called from a drop target node in the scene graph.
Subsequent to {javafx.scene.transfer.DragEvent#accept()}, the target node should retrieve the drag gesture's data via the {javafx.scene.transfer.DragEvent#dragboard}
At the completion of a drop, the target node is required to call {javafx.scene.transfer.DragEvent#dropComplete(boolean))}.
Note: The data transfer should be completed before the call to {javafx.scene.transfer.DragEvent#dropComplete(boolean))}. After that, the transfer of data can only succeed if the data transfer is local (within the same VM hosting the running JavaFX code).

Specified by:

drop in interface com.sun.javafx.tk.TKDropTargetListener

Parameters:

e - a drop target drop event

Returns:

transfer mode chosen by target
