It doesn't work that way. The wxRect returned from GetItemRect is not the 
actual rectangle object used by the control but rather a copy. In fact, on 
Windows the native control uses a RECT structure which is translated to a 
new instance of wxRect to be returned. AFAICT we don't have any way to 
change the size of ListCtrl items, but you may be able to do something with 
UltimateListCtrl in AGW. Perhaps via a custom derived class.
