Question

Does Qt have a built-in way to inflate or grow a rectangle? Like .NET’s Rectangle.Inflate or Java’s Rectangle.grow… or do I have to implement my own? I’ve looked through the docs and couldn’t find one but maybe I’m missing something.

Answer 1

There seems to be an adjust function that comes closest to what you want. You could easily use it to "inflate" a rectangle:

rect.adjust(-dx, -dy, dx, dy);

where dx and dy are the amounts you want to inflate in the x and y directions.
