Bug 267056

Description Enrico Zanaga 2009-03-04 12:08:18 EST

Having two shells with ShellListeners attached and a button for activate the other shell, the shellActivated and shellDeactivated events don't fire when the setActive method is called.
Also, shellDeactivated event doesn't fire in active shell when another shell is created.

In SWT the events are always fired correctly.

Here's a snippet with a simple log:

public class RapTest implements IEntryPoint {

    private Display d;
    private Shell s1;
    private Shell s2;

    @Override
    public int createUI() {
        d = new Display();
        s1 = new Shell(d, SWT.SHELL_TRIM | SWT.NO_FOCUS);
        s2 = new Shell(d, SWT.SHELL_TRIM | SWT.NO_FOCUS);
        s1.setBounds(0, 0, 400, 200);
        s2.setBounds(400, 0, 400, 200);
        s1.setLayout(new FillLayout());
        s2.setLayout(new FillLayout());

        s1.addShellListener(new ShellAdapter() {
            @Override
            public void shellActivated(ShellEvent e) {
                System.out.println("s1: shellActivated");
            }
            @Override
            public void shellDeactivated(ShellEvent e) {
                System.out.println("s1: shellDeactivated");
            }
        });
        s2.addShellListener(new ShellAdapter() {
            @Override
            public void shellActivated(ShellEvent e) {
                System.out.println("s2: shellActivated");
            }
            @Override
            public void shellDeactivated(ShellEvent e) {
                System.out.println("s2: shellDeactivated");
            }
        });

        Button b1 = new Button(s1, SWT.PUSH);
        Button b2 = new Button(s2, SWT.PUSH);
        b1.setText("activate s2");
        b2.setText("activate s1");

        b1.addSelectionListener(new SelectionAdapter() {
            @Override
            public void widgetSelected(SelectionEvent e) {
                System.out.println("b1: widgetSelected");
                s2.setActive();
            }
        });
        b2.addSelectionListener(new SelectionAdapter() {
            @Override
            public void widgetSelected(SelectionEvent e) {
                System.out.println("b2: widgetSelected");
                s1.setActive();
            }
        });

        s1.open();
        s2.open();

        while( !s1.isDisposed() && !s2.isDisposed() )
            if( !d.readAndDispatch() )
                d.sleep();
        d.dispose();

        return 0;
    }
}
