why tabLayout wont fire off the dropCallback? dragCallback is alright but not dropCallback.
I tried to search the boards but with no luck.
what Im trying to do is to build a UIbuilder which has a control list and a template window. you can drag the controls from the control list window to the template window, then drag it around to reposition and resize(ctrl + MMB then type in the new size, since i cant find a way to do drag-resize with mel, or is there?) the control in the tamplate window. I just started, so far I done the formLayout and button with no problem.
If the tabLayout mean not to fire off the dropCallback for some reason. then is there a way around?
Thanks in advance!

your doing the same thing as me then ![]() im testing this. I supect the tab controll isnt the box undernearh but just the tab istelf as theres lots of things like this you cant do with a tab.

Cool !! It is really good to know we are doing the same thing. ![]()
Drag resize the control is one thing, but what about the tabLayout and dropCallback? Why tabLayout wont fire off the dropCallback?
Hope you find a workaround!

Well actually im doing something that will eventually be a editor that lets you edit the exsisting maya gui. long way off tough since i don't personally need it for anything i can already do it by typing. But its rather for other people.
