Control live resizing

Hi , I wish to know how I can do the following please…
I want whenever the mouse-pointer enters my control then the control size to change the size, like to be double its size (cause I don’t see very well) and the VSTGUI should allow the normal usage of fiddling with the control and when the mouse leaves the control then it should revert to its original size.

This question has been answered by the ‘animation test’ sample in vstgui/tests/uidescription vst3.

Although… Uidescription test examples do not work
