[Qt-interest] clear QGridLayout

[Malyushytsky, Alex]

If you want to delete objects anyway, why do you need to be able to cast QObject to QWidget?

If you do need you might want to use standard C++ methods to cast pointers or QT provides qobject_cast, which you can use,
if you are sure that you have QObject derived class.

And the simplest would be delete layout itself. It would delete all children.
So all you would need is to create new layout.

Subject: [Qt-interest] clear QGridLayout

Hi,

i do have one QGridLayout where i want to remove all children.
Firsty i have the Problem i have also Layouts. But i had put them into a
Widget.
Now i want to pick the children with grid->children().
But so i have them as QObject not QWidget.

So my question, how can I convert the QObject into QWidget,
or is there one better way to clear a QGridLayout?

Thanks very, very, very!!!
