hey i solved i was deleting the widget which was not there may be that was the problem. and second thing is i was not using setWidgetResizable(True) so stuff inside scroll area was not visible in ui.
yes you’re right dictionaries will never in order so i am using list as a value so the list will be always in order. may be now you have figured out that i am working on rig tool so there can be multiple hand leg modules and many more module with multiple LODs. So my idea is to save all the data into dictionary and save that dictionary as string attribute to null transform node in maya. so whenever i open ui if dictionary found the ui will be updated accordingly. if you don't mind, I would like to hear the suggestion to make more efficient. > On 30-May-2020, at 3:20 AM, Justin Israel <justinisr...@gmail.com> wrote: > > > > On Sat, May 30, 2020, 7:31 AM Soham Parmar <soham...@gmail.com > <mailto:soham...@gmail.com>> wrote: > Hi, > I am trying to create scrollArea under my tabWidget. > I have already written code for creating widgets under my tab widgets but now > i wanted scrollArea. running code with scrollArea i can not se any Widgets in > my scrollArea and maya is geting crached if i move the window or change the > tab. > > Below Code is working perfectly fine WITHOUT scrollArea In my tabWidget: > def buildTabLodUpdate(self): > #
