Hi all,
I am searching for a while but can't find an answer. When I create a new
figure on a diagram the mouse position is always the left upper corner
of the figure. But in my application the mouse position should be the
center of the figure. What do I have to do to change this behaviour?
Regards,
Frank

Hi,
thanks for your answer. Your solution works fine, but I have different
shapes with different sizes. How can I find out in the getContraintFor
method which shape should be created by the command to calculate the
center position?

Frank
