get ColorPicker window

Hey,

is there a way to get the Window of the color picker without pressing the colorpicker Button component, something like if i click on a Item in a basic menu something like "set Color" i get the window of the color picker .

I have tryed this but its not working :

config.addItem("Set Color", new Command() {
			public void menuSelected(MenuItem selectedItem) {
                if (colorPicker.getWindow().getParent() != null) {
                	viewContent.getWindow().showNotification(
                            "Window is already open");
                } else {
                    viewContent.getWindow().addWindow(colorPicker.getWindow());
                }
			}
		});

i was hoping for colorpicker.popup() or colorPicker.open() but it looks like there are no such methods ^^
