Hi,

is it possible to listen to size change events before they occur so I can cancel it if I want to?
There is an event sizeChanged, but that's after the change.

Thanks in advance.

Thanks for the hint. I'll try that out. In my app, there are 5 diagrams aligned horizontally to each other. When I create a node on the very left diagram and delete that node, the parent diagram of that node increases its width and breaking the design. So I want to prevent the size changed (but I want to accept the size changed when the window is changed, therefore I thought I couldnt simply handle it with a boolean like 'allowResizing').
