Hello,
I have a problem with layout of composites in my application. I am developping an RCP application in which I have a multipage editor. One of the page contains several sections (one above each other).
In one of these sections, I have a composite and two buttons and a grid layout. The composite is two column width, so my buttons are under the composite.
This composite can contain mutliple children and these children can be added/removed by the user at runtime. I use a grid layout in my composite.
The problem is that I can't find a way to automatically resize my section (which contains the composite) when a new child is added/removed in the composite.
I tried to call layout on the composite (the container), and on the section, but the section doesn't resize properly: it keeps the same size. It means that when I add a new child in the container, the child is not visible and the only way to make it visible is to close/reopen the section (in which case, the layout is correct).
What could be the problem ?
Thanks

Hi,
Calling layout() on a Composite does not resize the Composite, it just lays
out its children again. To resize the Composite you should call layout() on
its parent if the parent is using a layout, or pack() the Composite
otherwise.

Hi Grant,
Thanks for your answer. I now call layout() on the top parent (the form body of the editor page) and this seems to fix the problem.
Thanks !
Cédric
