Qt Creator is useless!
2019/10/01 2:32 AM (UTC -5) | tildearrow
you can't even use a Positioner object!
trying to do so crashes the GUI, and I really don't know why. but seriously? what sort of QA did this thing go through? none?!?!?! you know, the community aren't the only users of Qt. there are companies that pay you to use their products, and what do you deliver? this?
seriously, it's more or less of a joke! who wants a GUI designer that will crash on the MOST BASIC FEATURE - the positioner!!!!
it's my first time using Qt and this is what I get.

seriously, Qt developers? what sort of joke did you make here!!!!!
what else can I use to create a GUI?!?! NOTHING!??!?!?!?~! come on! don't make me have to keep writing my very own UI toolkit just for this...
and fix this stupid crash!!!
