QPenWidget & QBrushWidget

[lni]

Can Qt provide QPenWidget & QBrushWidget?

It is useful for editing a QGraphicsItem that need.

It is similar to QColorDialog, but don't make it a dialog, since it is hard to be embedded inside other QWidget...

QPenWidget and QBrushWidget do not exist... you're going to have to develop them yourself.

However, Qt Solutions has a color picker, although you'll need a commercial license:

You might want to do a bit more research on this.
