e.g.
Rectangle rect(Rectangle r) {
_rect = r;
redraw();
return _rect;
}
If you allow
widget.rect.w = 200;
widget.rect.h = 100;
you will have to write much more code to handle the painting correctly.
and we don't want to call redraw twice here
I've dealt with that sort of thing in C# and it's a trivial issue. When
you
write code such as the above, it's very clear that you're changing the
rect
twice. If that's a problem, you just do this:
widget.rect = Rect(200, 100);
Rect has 4 values (x, y, width, height), otherwise, the example doesn't
make much sense.
