Hi
I try to implement the snapToGuide feature in my GEF Editor.
Now I have some trouble with them and need help.
1.
==----==
I have copied the code for the SnapTo'G..' in the logic simulator GEF example.
- I see the ruler at the left and the top of my Editor
- I can insert/remove Guides.
- I can move these Guides.
BUT(!!) I don't know how to attach an edit part/model to this Guid's.
The code in the >>My_XYLayoutEditPolicy<< checks an attribute of the
request to determine a possible Guid - but the variable *(guidePos* is always null.
(see code snipet below)
I can't find the code to set the extendedData in the request.
2.
==----==
The Guid at the left draws a horizontal line and the Guide at top draws
a horizontal(!) line too!
==----==
Any idea?!!!
greetings
Andreas

int alignment = ((Integer)request.getExtendedData().get(horizontal ?
snapToGuides.KEY_HORIZONTAL_ANCHOR :
SnapToGuides.KEY_VERTICAL_ANCHOR)).intValue();
ChangeGuideCommand cgm = new ChangeGuideCommand(part, horizontal);
cgm.setNewGuide(findGuideAt(guidePos.intValue(), horizontal), alignment);
result = result.chain(cgm);
}
return result;
}
