I need to make user possible to resize a Label or PlainTextEdit object. I mean the thing like in Qt Creator. If you select your widget some squares appear on it's corner and on halves of the edges. If you move a square you can resize your object. I need to make the exact same thing inside a Qt window. Is it possible to make it faster rather than just drawing all squares with code and catching the moment when user grabs a square and moves it?
I'm wondering since Qt is written in Qt... Maybe there is an easy option.
