Auto Size of nodes [message #229565]

Hello again,
I override refreshBounds() method for auto size a node when adding it to
the diagramm.

Then I used this tutorial
wiki.eclipse.org/GMF_Newsgroup_Q_and_A#How_to_create_require d_elements_on_diagram_when_created.3F
to automatically add the nodes in a new diagramm.

The problem is that refreshBounds() didnt get called, so the auto size
doesnt work when adding the nodes automatically.

I didnt find a working way yet, maybe u can help me.

Any hint how to force that refreshBounds() get called ?

Problem is not that refreshBounds() didnt get called, problem is that
Dimension of the editor is 0 when I use following code:

// size of editor
Dimension editorDimension =
((GraphicalEditPart)getParent()).getFigure().getSize();

Why do you need it - node will be created with preferred size by default
so you can "autosize" it by specifying proper preferred sizes for all the
child elements.

I need it because I want that those 2 node fill the complete editor area.

Hello Patrick,

Ok. Then try calling <diagramFigure>.getClientArea() to diagram size.

I tried many methods to get the size of the panel, but looks like when I
add nodes with <Model>DiagramEditorUtil#createInitialModel() and
refreshBounds() is calling because of that all size parameters of various
parents are 0.

Maybe I can add the nodes later in the code after the editor is fully
initialized ?

At least you can resize nodes later.
I think you can try listening for corresponding notifications and update
node size in accordance.
Another option which came to mi mind is to completelly override diagram figure
and make it fized in size..

Yes i could need a event to resize them, also when the editor panel size
is changing. I just searching in the code to get a point for hooking me
into

Alex,
i still didnt find a right notification to add and maximize a node when
creating a new diagramm. Maybe u can give me some hint where i to have to
look.
I only know it from the Microsoft world, there are events like "Shown",
they get called after a element is fully visible.
Do u have any idea where i could get this ?
Kind Regards
Patrick

I found a good solution.

I added an resize listener for the parent node. then i call my custom
refresh bounds method of the children in the resize handler.
