[solved] How to properly delete a QLayoutItem from the layout

[A Former User]

Hi there!
I'm trying to delete a Widget out of a layout. The widget can be at an arbitrary (but existing) position and lower items have to move up to close the gap. layout_m is of type QLayout,. Here's my delete member function:
if(index >= layout_m->count() || index < 0) return;
QLayoutItem* toDelete = layout_m->takeAt(index);
if(toDelete != 0){
toDelete->widget()->setParent(NULL);
delete toDelete;
requestedCount_m--;
}
This code is inspired from the QLayout documentation's description how to properly delete all contents of a layout. However, as you see, I use toDelete->widget()->setParent(NULL); to break ownership to the QLayoutItem. If I don't do that, the deleted item is still displayed in the parent widget, but not in the layout.
I conclude that my way to remove an item from a layout is unproper. How should I do that in a clean way?
Cheers,

@kalsan As far as I know, QLayout::takeAt() doesn't remove the widget of the QLayoutItem from its parent widget.

So I think your code is ok. Anyway, take a look at QLayout::removeWidget. I don't know all your code, but maybe you should remove the widget from the layout using that method.

I just call:

widgetToRemoveFromLayout.close();
delete widgetToRemoveFromLayout;

everything else does the layout on its own.

@msue Right then :)
