Problem clicking popup menu (stays visible) [message #551300] Thu, 05 August 2010 20:15

Hallo,

I am running into trouble when trying to click a popup menu within an SWTBot test. I am able to find the popup menu via EventContextMenuFinder and I am also able to click the menu (i.e. the SWT.Selection event arrives at the menu). However, the menu is not hidden (and thus the thread showing the popup remains in its readAndDispatch loop). I have created a test case to reproduce my problem (see below).

An additional note: on MacOSX I was able to let the popup disappear by sending a keyboard event to the shell after having done the click (new SWTWorkbenchBot().activeShell().pressShortcut(Keystrokes.ESC )Wink, on Linux GTK not even this worked. Any ideas?

Cheers,
Alexander
