Widgets promoting
-
Hello.
Could anybody tell me, how does the widget promotion affect the performance? Is it the same as I declare some class and after all use the inheritance from that widget(which one was mentioned in the line above)?
For instance, I have a QTreeWidget object and the class Test. And I promote it(tree widget) to the class Test. So, will be it the same, as I simply make QTreeWidget the base class of the class Test?
Thank you beforehand for answers.

Your Test class will be used in the code. It has no relation to QTreeWidget in the code, the base widget is used only as a placeholder in designer.
Try to go for some widget close to the one you implement yourself -- not only wrt. looks, but also with size hints, etc. -- to get the best possible preview results.

Thank you for you answer.
So, as I understood, I'd better re-implement the widget and put in all properties, what I want, than I'd promote it. Am I right?
