Re-enabling Direct Editing Mode [message #849950]

Hey, so I followed the tutorial for adding a DirectEditingFeature and it works fine. I add the pictogram element which can be direct edited and I'm able to edit the name, etc. I was wondering if there is an easy way to re-enable direct editing at some point after creation (like if the user double clicks on text, I'd like to enable direct editing again). I noticed there is a function in IFeatureProviderWithPatterns called "activateDirectEditingForPatterns". So what I did was create a ICustomFeature which calls, in its execute method, that function and I return the custom feature from the ToolBehaviorProvider "getDoubleClickFeature". So all of that works fine, I double click on the pictogram element I want to re-enable direct editing on and "activateDirectEditingForPatterns" is called and everything seems to be working as designed with one small problem, I need to move the pictogram element after calling "activateDirectEditingForPatterns" before the editable text box will show up and allow me to edit.. which I can of course get around by overriding the function and moving the PE after direct editing mode is enabled.. but that is definitely a hack.

Does the procedure described above sound like how one would go about doing this? Or am I missing some simpler method? Seems like "activateDirectEditingForPatterns" shouldn't require me to move or otherwise update the PE in order to get direct editing turned on right?

Thanks,
Craig

Using that pattern-related method seems a bit odd when you have a plain
custom feature to enable that. I would suggest to use the direct editing
info stored at the feature provider to provide what should be edited (as
done in the add feature in the tutorial) and then triggering an editor
refresh (needed to activate direct editing mode for the editor). Something
like that in the custom feature will do:

IDirectEditingInfo directEditingInfo =
getFeatureProvider().getDirectEditingInfo();
directEditingInfo.setMainPictogramElement(pe);
directEditingInfo.setPictogramElement(textPE);
directEditingInfo.setGraphicsAlgorithm(textGA);
directEditingInfo.setActive(true);

getFeatureProvider().getDiagramTypeProvider().getDiagramEditor().refresh();
