Hi Vincent,
did you solve this? I think your direction is good.
Does the new default background color show up in the editor?
If so it should also be possible to change dynamically.
I'm not sure from what context you want to change the color,
but if you have access to your XXXEditPart, it should be fine.
If you want this with a context menu (popupmenu), see one of the GMF
tutorials.
I did something like this:
> GraphicalEditPart part = ....;
> TransactionalEditingDomain ted = part.getEditingDomain();
> CompoundCommand cc = new CompoundCommand();
> View v = (View) part.getModel();
> if (v instanceof FillStyle) {
> SetCommand cmd = new SetCommand(ted, v, NotationPackage.Literals.FILL_STYLE__FILL_COLOR, 0xffaabb);
> cc.append(cmd);
> }
> ted.getCommandStack().execute(cc);
You can have look at org.eclipse.gmf.runtime.notation
model/notation.ecore for more details.
The class hierarchy looks something like this:
View -> EModelElement
Node -> View
Style
FillStyle -> Style
fillColor
ShapeStyle -> FillStyle, ...
Shape -> Node, ShapeStyle
Somehow, the gmf notation view representing the figure should be a Shape.
I'm not sure how/where the exact mapping is...
Also I cannot really find where the Shape/ShapeImpl is created.
Anybody knows?
If you want to see how the default colors/settings are created, have a
look at XXXViewProvider's createXXX_XXXX functions.
Example:
> final IPreferenceStore prefStore = (IPreferenceStore) XXXXEditorPlugin.DIAGRAM_PREFERENCES_HINT.getPreferenceStore();
> org.eclipse.swt.graphics.RGB fillRGB = PreferenceConverter.getColor(prefStore, IPreferenceConstants.PREF_FILL_COLOR);
Hope this helps,
Best,
Ivar
