PyQtFlowLayout

The flow layout that many have shared from the given examples needs additional methods to become really useful, in particular, I needed it to be able to propagate up into a scrollable wrapper.

Example

Usage:

scroller = ScrollingFlowWidget()
scroller.addWidget( QtGui.QPushButton("Push Me") )
scroller.addWidget( QtGui.QPushButton("Don't push") )
...
