Problem with GridLayout used in a Group on a TabItem in View

[racs]

We are evaluating the swt-designer 4.0.1 on eclipse 3.0.2 as we are trying to rewrite our native application to become a Eclipse RCP-Application.
So I created a new ViewPart and added all required Fields to match our old application.
In Desing / Preview everything looks fine, but at runtime the labels, text fields and so on which are located in a Group with a GridLayout don´t appear.
If I remove the GridLayout from the Group everything is fine.... Any suggestions???

With visible Fields at preview


Without the Fields at Runtime:

Code: Select all

In Desing / Preview everything looks fine, but at runtime the labels, text fields and so on which are located in a Group with a GridLayout don´t appear. If I remove the GridLayout from the Group everything is fine.... Any suggestions?

You are running into a runtime bug within SWT itself. Basically, you can't mix null layout at a higher level with complex layouts (like GridLayout or FormLayout) at a lower level.

If you want to use GridLayout within some of your tab pages, you need to use GridLayout for your top-level composite and tab page composites as well.

All you need to do is drop a GridLayout on the top-level container and each of the tab page composites. For the top-level container, I would suggest making it a three column grid with your tabfolder and navigation group spanning three columns. The three buttons will need to move up in the creation order and the second button will need to be right justified and grab the excess horizontal space. Give all three buttons width and height hints and that should allow you to replicate the layout you have now (at least it did when I tried it).

Thx a lot for the fast help. After adding GridLayouts where needed it worked fine.
The only thing which caused some problems was the GridLayout on the top-level composite. It was not possible to get the three Buttons all in place (because the first button took the complete space , so the others where outside the displayed area. I solved it by putting the Buttons in a Group of their own..

The top-level composite needed a three column grid. Each button would occupy one column and the tabfolder and navigation group would each span all three columns. I was able to replicate you original layout very easily that way, and nothing was outside of the display area.
