Example 5 with Source

the class DataBrowserEditor method hookDragAndDrop.

/**
 * Allow 'drop' of PV name, archive, ..
 *  @param canvas FXCanvas
 */
private void hookDragAndDrop(final Control canvas) {
    // CS-Studio uses the ControlSystemDragSource
    // and ControlSystemDropTarget to transfer its own
    // data types, using the SWT drag-and-drop API
    // plus some class loader hacking to de-serialize
    // types from other plugins.
    // 
    // The JavaFX plot is inside an FXCanvas.
    // The FXCanvas establishes an SWT DropTarget
    // to forward drops from SWT to the hosted JavaFX scene.
    // 
    // Issues:
    // The FXCanvas only reliably forwards standard transfers
    // (string, ..), and not custom data types.
    // SWT generally doesn't allow multiple drop targets.
    // 
    // Option 1)
    // Use the JavaFX drop API on the plot, and parse the received strings.
    // -> Don't want to parse possibly arbitrary strings.
    // 
    // Option 2)
    // Change the ControlSystemDropTarget to use
    // getSite().getService(IDragAndDropService.class).addMergedDropTarget(..)
    // https://bugs.eclipse.org/bugs/show_bug.cgi?id=162192

    // but requires changes to the ControlSystemDropTarget,
    // would only work in RCP, not plain SWT.
    // Who then receives the drop events would depend on the order
    // in which drop targets are added and which transfers they use.
    // 
    // Option 3)
    // Hack around the SWT limitation by fetching
    // the FXCanva's DropTarget via
    // control.getData(DND.DROP_TARGET_KEY);
    // and disposing it.
    // Checking the source code for the SWT DropTarget
