QTableView and It's Model, Decoration Role With Rectangle

[DzCode]

Hi everyone,

I know that we can put a color inside decoration role of the model.

What about ptting a rectabgle? I want to put a rectangle inside decoration role (whose inside is empty). However decoration role cannot be a QRect. Is there any way to do it without doing inside paintevent of the qtableview custom class or inside a delegate because it is very slow when we write it inside paintevent.

Also I need to give different color into each rectangle

Create an image with your rectangle and return it for the decoration role.

I've just edited my description. I have assign different colors for each rectangle. So that setting an image is not a proper way for me. I have more than 1k rows with different colors.

Then create an image per color and store them in a container

@Christian-Ehrlicher do you mean creating QPixMap?

[Christian Ehrlicher]

Decoration role accepts QPixmap, QImage, QIcon or a simple QColor - so yes create a pixmap for each color and return it accordingly.

@Christian-Ehrlicher Thank you
