Qt drawing a filled rounded rectangle with border

[Cupidvogel]

I want to draw a rectangle with rounded corners (border radius same for all 4 corners) with a specific color filing the entire rectangle, and a separate border color (say border is 1 px wide).

From my observation, Qt provides three methods - fillRect and drawRect and drawRoundedRect. There is, however, no method like fillRoundedRect. Which means that I can draw a rounded rectangle but it won't be filled with the color I want.

How do I do it? And also, I read that due to some aliasing problems, the corners are often rendered equal. How do I set it as equal for all four? Will painter.setRenderHint(QPainter::Antialiasing) suffice? Or do I have to do anything else?

The fillXYZ methods are just for convenience, to require less calls for the most common area types that need filling.

You can fill any area type by setting a brush on the painter before calling the respective draw function.

The pen decides the color of the border, the brush for the filling.
