Re: [platform-swt-dev] Display.asyncExec premepts pending events

["Steve Northover" <Steve_Northover@xxxxxxx>]

Randy, the following code works in the latest SWT, but fails in 2.0.

public static void main(String[] args) {
      final Display display = new Display ();
      final Color gray = display.getSystemColor (SWT.COLOR_GRAY);
      final Color darkGray = display.getSystemColor (SWT.COLOR_DARK_GRAY);
      Shell shell = new Shell (display);
      shell.setLayout (new RowLayout ());
      Button button1 = new Button (shell, SWT.NONE);
      button1.setText ("foo");
      Button button2 = new Button (shell, SWT.NONE);
      button2.setText ("foo");
      final Composite composite = new Composite (shell, SWT.NULL);
      composite.setLayoutData (new RowData (30, 30));
      display.asyncExec (new Runnable () {
            public void run () {
                  if (composite.isDisposed ()) return;
                  if (composite.getBackground ().equals (gray)) {
                        composite.setBackground (darkGray);
                  } else {
                        composite.setBackground (gray);
                  }
                  display.asyncExec (this);
            }
      });
      shell.setSize (300, 300);
      shell.open ();
      while (!shell.isDisposed ()) {
            if (!display.readAndDispatch ()) display.sleep ();
      }
      display.dispose ();
}
