How to disable all widgets on MainWindow except one
With
mainWindow->enable(false);
i can disable all widgets on it. But i want one of the widgets NOT to be disabled. Any ideas?
Of course i can disable them one by one, but it is lot of (inefficient) code.

QObject has
QObject::children (). With a simple loop you can disable all children and after that enable the one you don't want to disable.
Thanks Skizmo!
A notice: By doing
mainWindow->setEnabled(true);
it enables all widgets except those that were explicitly disabled, e.g. widget1->setDisabled(true);
In other words, it works the other way...
Problem still. There is hierarchy between widgets so if i disable a parent then all children are disabled and they can't be enabled after that!
Problem solved. I had to disable it in pieces.
