Howdy,

I am new to GMF but have followed the tutorial and got a simple diagram up
and running. I have been examining the gmfgen to figure out how it works.
I notice I have a Gen Editor **** test.diagram
-> Gen Diagram ***EditPart
-> Gen Plugin Test Plugin
-> Gen Editor View test.diagram.part
-> Gen Diagram Updater TestDiagramUpdater
-> Property Sheet test.diagram.sheet
-> Gen Application TestApplication

I want to remove the view that displays a small outline of the main window
and replace it with my own custom view. Before writing my custom view I
want to be sure this can be done in GMF, how do I change the gmfgen to let
me replace existing views?

Hope you can help!

Sam.

Hello Samuel,

You should change generated code instead. Eclipse Outline view calls getAdapter(IContentOutlinePage.class)
of the generated DiagramEditor, so i sugegst you to modify generated getAdapter()
method appropriately and return your implementation of IContentOutlinePage
from there (see DiagramEditor.getAdapter() for the default implementation).

Hello Alex,

Sorry if I do not understand all of the references you make. I have found
a number of references in the generated diagram code referring to
getAdapter(), 2 of which were in the diagram.edit.commands and one of
which in the diagram.edit.parts none of which refer to an
IContentOutlinePage.class

I did manage to break the views by changing the code in diagram.providers
TestViewProvider

private IElementType getSemanticElementType(IAdaptable semanticAdapter) {
if (semanticAdapter == null) {
return null;
}
//return (IElementType) semanticAdapter.getAdapter(IElementType.class);
//Removed this part!!!
return null;
}

Which is the only visible result I could manage so far. Am I on the right
track?

Thank you,

Sam.

Hello Samuel,

No.. ;-)
- Open generated XXXDiagramEditor.getAdapter() method
- modify "@generated" -> "@generated NOT" javadoc comment
- add
if (type == IContentOutlinePage.class) {
// return your IContentOutlinePage implementation from here
}

Default GMF implementation of IContentOutlinePage is:

TreeViewer viewer = new TreeViewer();
viewer.setRootEditPart(new DiagramRootTreeEditPart());
return new DiagramOutlinePage(viewer);

So you can use it as a prototype for your outlinepage..
