Jade,
I'm not sure if you can fix this easier using the generator, but you can
definitely fix this by customizing the generated code.
If your lollipop editpart is an AbstractBorderItemEditPart, you can call
getBorderItemLocator().getCurrentSideOfParent() to figure out which side
of the shape the lollipop is on and then rotate the lollipop figure
accordingly.
Regards,
Cherie

Hi all,
I have a similar case, and I partially found a solution (but maybe not
the best). I add some code in the refreshBounds() method to update my
figure (here I just change the color for testing purpose), but I still
have two remaining problems :
1. I need the following snippet of code in order to update the
currentSideOfParent property : getBorderItemLocator().relocate(getFigure());
Otherwise, the getBorderItemLocator().getCurrentSideOfParent() method
only returns the initial side (before the move is performed). Is there a
better way to do that.
2. My second problem is that the figure is not well initialized during
the first creation of the Figure (when I open the diagram).
Here is the code I used in my "PortEditPart" :
@Override
protected void refreshBounds() {
// Call relocate() to update the CurrentSideOfParent property
getBorderItemLocator().relocate(getFigure());
// Depending on the border the figure is attached, use a different figure
switch (getBorderItemLocator().getCurrentSideOfParent()) {
case PositionConstants.WEST:
getFigure().setForegroundColor(ColorConstants.orange);
break;
case PositionConstants.NORTH:
getFigure().setForegroundColor(ColorConstants.gray);
break;
case PositionConstants.EAST:
getFigure().setForegroundColor(ColorConstants.red);
break;
case PositionConstants.SOUTH:
getFigure().setForegroundColor(ColorConstants.yellow);
break;
default:
break;
}
super.refreshBounds();
}
Any help is welcome,
Regards,
Jacques

Hi All,
I have the same problem as Jacques describe with initialization, and also a
problem near the corners. The latter seems related to the snap-to-grid
feature.
Going back to the initial question of this thread (26-1-2007): How to rotate
the lollipop figure? Anybody a hint where to look? I already tried to
transform a polygon figure (see thread "How to rotate a border item" on
21-11-2007), but somehow the modifications are not displayed.
Kind regards,
Jaap
