[1.2.3] Can't constrain window with container

[The_Jackal]

Hi,

The following code won't constrain a window within a container.
I have seen examples using ExtJS, so either my code is wrong, there's a bug, or GXT can't do this yet.

If there is another way to do this, please guide me in the right direction.

    
    public void onModuleLoad()
    {
        ContentPanel center = new ContentPanel();
        center.add(new Html("Center"));
        center.setSize(400, 400);
        
        ContentPanel west = new ContentPanel();
        west.add(new Html("West"));
        west.setSize(100, 400);
        
        HorizontalPanel main = new HorizontalPanel();
        main.add(west);
        main.add(center);
        
        Window w = new Window();
        w.setSize(200, 200);
        w.setConstrain(true);
        w.setContainer(center.getElement());
        w.show();
    }

The container is only for maximazing the window. Not for dragging.

Hi,

I've see this done in ExtJS - for example in Saki's http://examples.extjs.eu

The panel/window -> Simple Window/Panel auto load example the window is limited to the center panel (see pic).

Can this be done in GXT?

Carl.

EXTJs is not exactly the same than GXT. I move this into the help forum.

I look into adding this for the GXT2.0 release.

Thanks Sven.

I do this already with GXT 1.2.3 with the following code

        Draggable draggable = getDraggable();
        draggable.setContainer(container);

where container is the Component that you want to use as container.

Hope this helps

[sven]

Yes draggable already has this.

Well those hints have a mostly working solution - I can constrain the title of the window (it's "draggable") to a container... which effectively means a window is contained in a center panel in every direction but south.

The code I used is

    private class ConstrainedWindow extends Window {
        private Container constrainContainer = null;
        public void setConstrainContainer(Container<Component> constrainContainer)
        {
            this.constrainContainer = constrainContainer;
        }
        
        @Override
        protected void afterRender()
        {
            super.afterRender();
            Draggable d = getDraggable();
            d.setContainer(constrainContainer);
        }
    };

Usage:

ConstrainedWindow w = new ConstrainedWindow();
w.setConstrainContainer(myContainer);
