Hi,
I've bin stuck with the following resizing problem for weeks and I can't
seem to find a solution nor the reason. I have an SWT/JFace
ApplicationWindow containing a ScrolledComposite that holds a Composite
having a StackLayout. The goal is to be able to stack within a
ScrolledComposite.
A Goto... Menu Actions adds composites to the StackLayout, but right
now, only my search Composite is giving me an headache. The search
Composite has a search Button that dynamically displays the results
(equipments) within Tabs. After insertion of a new Tab, I do a
getShell().pack(true); but for some reason, only the outer
ApplicationWindow resizes correctly and not what is within the StackLayout.
To better understand, I've added to this post a stripped version of my
search
application with three classes: the ApplicationWindow (v_navigator), the
search Composite (v_search) and the search results Composite (v_equipment).
The code is really simple.
If anyone can free me from my desperation I would truly appreciate.
Sebastien
P.S. Three classes follow
