How to draw a filled round rect?

Thanks, so it fills automatically when there is a brush deifned, which means I need to excplicitly set brush "on" and "off" if I want just the outline or filled round rect...
Why is it done like that for round rect, and for normal rect they offered a fillRect() methods?
Hmm...

Because fillRect is not for drawing rectangles. You should use QPainter::drawRect() for that. QPainter::fillRect() is for filling areas (and by the way, it takes a QBrush as its argument).

I know, fill rect FILLS rectangles.
Which means you have a method for drawing rects and a method for filling them.
But not so for round rects, where you only have one method for drawing which also fills it if the brush is set.
A drawRect will not fill a rect even if brush is set.

It is used for filling areas in general.

Like for all other shapes.

A drawRect will not fill a rect even if brush is set.

Are you sure? Try running the code from attachment.

I am not sure what do you mean by that...
Filling areas that are not rectangles as well?
How so?

Because there are methods for filling paths. I think these are only convienience methods. There are probably implemented using drawRect and drawPath with null pens. You can check that yourself in the source code. In short, the difference between drawRect and fillRect is that the latter doesn't use the pen.
