Re: [recommenders-dev] Capture a mouse click action outside a shell widg

[Madhuranga Lakjeewa <lakjeewadmm@xxxxxxxxx>]

Thank you very much Marcel.

This did not exactly work for my purpose. Because I have two shells and when i change the focus between them it captures that event also as a focus lost (which is correct. But i want both shells open when i go in between them).

Here is what i did;

        Display.getDefault().addFilter(SWT.FocusIn, new Listener() {

@Override

public void handleEvent(Event event) {

if (event.widget.equals(PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell()))

                        System.out.println("we lost focus");

myOwnPopupShell.dispose();

}

        });

This captures the click action on the active editor. Then i can dispose all the shells. At the end i remove the listener.

Thank you very much for the support.

Regards,
Madhuranga

Not sure whether this is the best solution but this should work:


        Display.getDefault().addFilter(SWT.FocusOut, new Listener() {

            @Override
            public void handleEvent(Event event) {

                for (Control c = (Control) event.widget; c != null; c = c.getParent()) {
                    if (c == myOwnPopupShell) {
                        System.out.println("we lost focus");
                        break;
                    }
                }
            }
        });


You may extend the listener to know which other shells exist you want to listen too. Please note that the listener MUST be unregistered as soon as the popup is disposed. Let me know whether this helps.
