[Qt-interest] How to layout with width-for-height ?

[Martin Schröer]

First see
http://qt.nokia.com/doc/4.5/layout.html#how-to-write-a-custom-layout-manager 

for a general overview.

The main thing is the implementation of setGeometry(const QRect &rect).
Example:

QLayout::setGeometry(rect);

QLayoutItem *item;

foreach (item, itemList)

{

        int x = rect.x();

        int y = rect.y();

        int w = rect.width();

        int h = rect.height();


       // do something, calculate coords for every item


       item->setGeometry(QRect(x, y, w, h));

}

Tadaa.
