Using the Qt Designer I've made a couple of QFrames in each other, each having a horizontal layout. Their stylesheet predicates that they should have no margin nor a padding. This means that in the Qt Designers view as well as in the final result, no space is seen between the QFrames.
Using drag-and-drop I can place widgets into the window, it shows a blue line where it will be placed (in a layout). However, it's impossible to add another QFrame to a QFrame parent I can't see (and thus drop on). There is also a tree in the right panel, but dropping on the parent makes it automatically go in one of the childs...
Example, I have this setup:
QMainWindow - QWidget - QFrame (parent) - QFrame (child) - QFrame (child)
Adding a new frame, whatever I try, gives me:
QMainWindow - QWidget - QFrame (parent) - QFrame (child) - QFrame (child) - QFrame (new child)
But I really want:
QMainWindow - QWidget - QFrame (parent) - QFrame (child) - QFrame (child) - QFrame (new parent)
Is there any feature I haven't discovered to accurately place new widgets?
