Hi there,
New on the forum, I'd like to thank all the askers and givers of answers for
they have been useful too me more than once...
Now I'd need a little help understanding why my collapse function doesn't
work (I didn't seem to find any previous answer to this, but please inform
me if I'm calling for an old Post, and what's the title) :
-the compartment is set on collapsible : true
-this is also visible in the code generation
-but when I open my application, the little triangle used to show if a
compartment is collapsible or not only let the information contained in this
compartment disappear or re-appear.
My problem is the Figure that owns the compartment doesn't get smaller to
addapt to the compartment collapse, so it isn't useful for space managing...
The tutorial 2 of GMF shows a collapse that works well : the compartment is
resized as well as the figure, we can see this in the first viewlet. I tried
to compare the code of the solution tutorial with mine and things seem Ok as
far as collapsing is conserned :
in the view Factory, the collapse is set with
setupCompartmentCollapsed(view);
/*and is defined in the same way as in the tutorial with :
/**
* @generated
*/
protected void setupCompartmentCollapsed(View view) {
DrawerStyle drawerStyle = (DrawerStyle) view
..getStyle(NotationPackage.eINSTANCE.getDrawerStyle());
if (drawerStyle != null) {
drawerStyle.setCollapsed(false);
}
}
Any Ideas ??
Thanks in advance,
Thanaele

Thanaele,
This is an interesting and important issue which seems to have been left
unanswered. I cannot help you either, since I'm also looking for a
solution yet.
As you have rightly pointed out, in the Mindmap example from the
tutorial the Topic compartment gets properly resized when collapsed but
in my own diagram editor it fails to do so.
I'm reiterating the question: does anybody have an idea how to make this
work?
Regards,
Robert

I haven't tried this yet, but maybe you could call autosize programmatically
every time the compartment is hidden?

Tobias,
You can see the behavior I need in this viewlet of the GMF tutorial part
2, around the 6:55 timeframe:
http://www.eclipse.org/gmf/tutorial/viewlets/tutorial2.html
When I click AutoSize, it only restores the compartment to its original
size. But what the tutorial shows it that the compartment memorizes two
sizes (one for collapsed and one for expanded) and switches between them
as you click the collapse button.

Robert

Vinary,
I did not observe that behavior when the compartment is resized. Thanks
for pointing this out.
Under these circumstances, I rephrase my original question :-) How can
the compartments be programatically resized when clicking the "collapse"
button?
Regards,
Robert
