See if this code snippet helps. BTW, no need to really allocate any memory
if you just want to find out how big an object is.
UInt16 myGetButtonWidth(UInt16 buttonID){
FormPtr form=FrmGetActiveForm();
RectangleType r={{0,0},{0,0}};
FrmGetObjectBounds (form, FrmGetObjectIndex(form,buttonID), &r);
Return r.extent.x;
}

Bob:
Thanks for your answer, but I can�t figure out what you are trying to
explain very well (sorry). Moreover, previously to call
'FrmGetObjectBounds()', I do:
MemSet(&rtObject, sizeof(rtObject), 0);
to initialize the Rectangle Type variable in wich I want to get the
results of 'FrmGetObjectBounds()' ('rtObject' variable).
You tell me that I have to update the size of the rectangle to match the
object that I want to test. But... how can I do that?
