Hi,
I had the same problem and ended up overriding the _calculateSize method as you
are doing.
However, I don't think this is an error of the bounding box. What happens
internally is that the text has a width and height according to the first text
that we fit in, and it's only updated IF the text occupies more space, shall it
be width or heigth.
On the other hand, I think it's not a good approach to remove completely the if
statement, because that would imply the size of the box is always going to be
that one of the text's. Eg. suppose you want a bigger container with a
background color specified by user's width and height.
I went for two booleans, "_userWidth" and "_userHeight" which are set whenever
the user wants to define a custom width or height (in the setters and adders).
With this, the _calculateSize looks like this:
Code:
void EnhancedWidgetText::_calculateSize(const osgWidget::XYCoord& size){
if(!_userWidth || getWidth() < size.x())
inherited::setWidth(size.x());
if(!_userHeight || getHeight() < size.y())
inherited::setHeight(size.y());
}
If someone is interested I can provide the implementation.
Btw, among other things, you'll find out the padding is not supported in canvas
widgets. An addition could be added in this direction, maybe.
Cheers,
Daniel
