using a composite on a docking panel

[BoothMartin]

using a composite on a docking panel:

This is pretty basic, but I am just learning and can't figure out where to look for the answer.

I have a docking panel with various widgets on it. One of those widgets is a composite panel made of a stacking panel with check boxes; another widget is a composite placed on the center panel of the docking panel.

I can not figure out how to have something happen on the composite panel on the center panel of the docking panel when a check box is checked on the stacking panel.

Here is the code I am trying to use:

Code: Select all

checkBox.addClickListener(new ClickListener() {
   public void onClick(final Widget sender) {
      final Frame frame = new Frame("query.txt");
      absolutePanel.add(frame, 20, 65);
      frame.setSize("800", "500");
   }
});

The best place to get answers to general GWT questions is Google's GWT forum.

hi Martin,

If I understand well problem you simply should expose your subcomponents from composite so they are available in design view for custom event assignment, see docs:
viewtopic.php?t=1045
and option "expose widget" description,

Google's GWT forum is still the best place to go to get answers to general GWT questions like this.

For questions specific to GWT Designer, I would recommend starting with the GWT Designer docs and flash movies.

The docs and associated flash movies show how to expose individual widgets and properties from custom composites.

Note that exposing widgets or properties from a Composite (or any class) is a basic Java concept that can be easily addressed via hand-coding as well.
