// NOTE: You'll find this example very similar to osgwidgetwindow. However, here we
|
|
// demonstrate a bit of subclassing of Widget so that we can respond to events
|
|
// such as mouseEnter and mouseLeave. We also demonstrate the use of padding, though
|
|
// fill and alignment should be working too.
