This is still reproducible on 4.7, Fedora 25, with GTK3.22.15. Bug triaged, visit https://wiki.eclipse.org/SWT/Devel/Triage for more inforamation. This is not reproducible anymore on Fedora 29, GTK3.24 using SWT master as of today. Closing. Please reopen if the issue reoccurs. |
Shell shell = new Shell(); shell.setLayout(new FillLayout()); shell.addListener(SWT.MouseExit, new Listener(){ public void handleEvent(Event event) { System.out.println("exit"); } }); shell.addMouseListener(new MouseAdapter() { public void mouseDown(MouseEvent e) { System.out.println("down"); } public void mouseUp(MouseEvent e) { System.out.println("up"); } }); DragSource ds = new DragSource(shell, DND.DROP_COPY); ds.setTransfer(new Transfer[] {TextTransfer.getInstance()}); ds.addDragListener(new DragSourceAdapter() { public void dragStart(DragSourceEvent event) { System.out.println("Drag Start"); } }); shell.open(); Display display = Display.getDefault(); while (!shell.isDisposed()) if (!display.readAndDispatch()) display.sleep(); If you press the mouse on the Shell and drag somewhat quickly out of the Shell, you will get a MouseExit event. This never happens on win32, and randomly occurs on GTK. I would guess that Motif has the same problem.
