Growing the contents of a scroll area.

[spraff]

Hello, and thanks for reading.

Consider a class Foo which is something like

Foo :: Foo (QWidget * parent) : QWidget(parent) {
	my_layout = new QVBoxLayout (this);
	setLayout (my_layout);
}
 
void Foo :: bar () {
	my_layout -> addWidget (new SomeWidget());
}

Foo :: Foo (QWidget * parent) : QWidget(parent) {
	my_layout = new QVBoxLayout (this);
	setLayout (my_layout);
}

void Foo :: bar () {
	my_layout -> addWidget (new SomeWidget());
}

To copy to clipboard, switch view to plain text mode 

If Foo inherits from QWidget then it behaves as expected: the height increases to accomodate the contens every time bar() is called.

If this grows to big I need a vertical scrollbar. However, if Foo inherits from QScrollArea then it does not resize to fit the new contents; rather, the new widgets are squashed together. Ironically, this makes the scrollbar redundant.

How to I make Foo stack the child widgets correctly as in the non-scrolling version?

Thanks

Use QScrollArea::setWidgetResizable().
