Hi,

I'm trying to fill a screen with a composite, then at somepoint this composite gets hidden, and a new one is created which also needs to fill the screen.. eventually this is disposed and the original composite is called back with setVisible(true).

Now, before I used layout managers within these composites I was simply using setSize( screen width, height) to fill the screen with them. But this seems to no longer work (just a white screen appears).

So I decided to try using fill layout on the shell; which works for the first screen, but no matter what I do (create new filllayout/call layout() etc.) I can't get the second to appear.. (once again it will just turn into a white screen).

Argh, help? :)

Coding this for a pocketpc, first time using SWT.

Matt,

The StackLayout is what your need.
Make sure you call shell.layout() after changing the topControl value of
the layout.

Olivier.

Sounds like the right time to use StackLayout. Only one control at a time
is visible in this layout.

this.stackComposite = new Composite(parent,SWT.NONE);

this.stackLayout = new StackLayout();
this.stackComposite.setLayout(this.stackLayout);

Control nextTopControl = new ...

this.stackLayout.topControl = nextTopControl;
this.stackCanvas.layout();

hth,

Ricky

I thought that.. but there is no stack layout..

Perharps it's because it's a SWT implementation for WinCE?

Right.. so I've managed to get it working with FillLayout..

The second composite is there if I set items using setBounds.. but as soon as I try to use a layout on it (e.g. gridlayout).. nothing will appear..
(I know the layout code is correct as it's the same code being used on the first composite!)..

argh?! :(
