> At least with antialiasing Trolltech will tell you that you need XRender. But what do I need for Plasma to work? I have no clue because Trolltech hasn't disclosed the requirements of WoC.

On the technical side, the whole trick about WoC is that a QWidget has QPaintDevice as its base class. That means that a QWidget can be "drawed" on every painting base (such as a display, a printed document, or a QGraphicsView which the Plasma desktop is derived of).

The technical requirements for the drawing process depend on the render hints set by the application (for example: antialiasing and bilinear filtering) and, of course, on the implementation of the drawing process (for example: which external libraries are used). All of these requirements are set by Trolltech through the implementation of Qt.

To come back to your question: A QWidget is essentially the same as a rectangle or an image (= an object that can be drawed on some display). If your machine can paint rectangles or images on the Plasma desktop, it will definitely also be able to paint widgets on the desktop.
