Bug 22594

Comment 1 Steve Northover 2002-08-21 11:43:24 EDT

The following code shows that SWT.Selection for Tree comes in before SWT.Show 
for Menu when the right button is pressed:

import org.eclipse.swt.*;
import org.eclipse.swt.widgets.*;
import org.eclipse.swt.layout.*;

public class PR_22594 {

public static void main (String [] args) {
	Display display = new Display ();
	Shell shell = new Shell (display);
	final Tree tree = new Tree (shell, SWT.BORDER);
	for (int i=0; i<16; i++) {
		TreeItem item = new TreeItem (tree, SWT.NONE);
		item.setText ("Item " + i);
	}
	Menu menu = new Menu (shell, SWT.POP_UP);
	for (int i=0; i<16; i++) {
		MenuItem item = new MenuItem (menu, SWT.NONE);
		item.setText ("Item " + i);
	}
	tree.setMenu (menu);
	Listener listener = new Listener () {
		public void handleEvent (Event event) {
			String name = event.type == 
SWT.Show ? "Show" : "Selection";
			System.out.print (name + ": {");
			TreeItem [] selection = tree.getSelection ();
			for (int i=0; i<selection.length; i++) {
				System.out.print (selection [i] + " ");
			}
			
			System.out.println ("}");
		}
	};
	menu.addListener (SWT.Show, listener);
	tree.addListener (SWT.Selection, listener);
	
	shell.setLayout (new FillLayout ());
	tree.pack ();
	shell.pack ();
	shell.open ();
	while (!shell.isDisposed ()) {
		if (!display.readAndDispatch ()) display.sleep ();
	}
	display.dispose ();
}

}

Sorry, my recollection was incorrect.  Next time I'll write the testcase.

The situation in which selection used to not occur was on DragStart, not 
menuPopup.  It appears that this has been fixed in 2.0.0.
