QScrollArea and QVBoxLayout issues with dynamically added widgets

[dryajov]

Im running into a weird issue with dynamically added widgets to a QVBoxLayout contained inside a QScrollArea. If I add the widgets it works as expected, however after all widgets are removed, there are still some left overs on the screen. Is this a bug? Can someone else reproduce it?

@
delete ui->verticalLayout->takeAt(0);

is not enough to also remove the widgets.

You should do this:
@
QLayoutItem *child;
while ((child = layout->takeAt(0)) != 0)
{
delete child->widget();
delete child;
}

That seems to have done it. The important bit seems to be:

delete child->widget;

Because I did try deleting just the LayoutItem in my work project.

Thanks!
