2 different custom paintevents are not working

[anda_skoa]

That looks fairly ok (other than then obvious unnecessary save/restore).

So you have two instances of that label?
In a layout?
With different data?

Yes, two instances of the label. I also tried to use two different classes instead of instancing. Same result.

I added them to the same layout. The data is different. But it seems that the paint event from "label1" is also applied on "label2". I try to provide the whole code in a simplified way so you can understand the problem better. Maybe it is something very simple.

I attached a simple project.

The window shows 2 large labels in white. Try painting on the first one. It will also paint onto the lower one.

I guess that the problem here is that paintEvent will be triggered for every label. But it is strange that it also paints inside the 2nd label. When I paint onto the 2nd label nothing happens.

So you have two labels that draw the same data and you are surprised that they look identical?

I found my mistake by trying it with another approach (promoting a custom class via the gui). I put all the globals into the custom label class and now every label has its own values. Damn i forgot about the the attributes of an objects.

You know, I asked you if the two instances had different data.
A reasonable approach would have been to check that before answering yes despite the facts pointing to the opposite.

I thought they were different. At least I thought that the MousePos were Screen Positions. Because the coordinates are based on the widget coordinates they are also appearing in the 2nd widget.

And in my last reply I already said that I did a mistake.

No, that's not the cause at all.
What the data contains is totally irrelevant.

You are using the same list of points, literally the exactly the same data.
