Is there simple way to automate button size according to text? #5

so I don't have to write button.setSize(<some formula to guess the size>);

See Button.resizeToContents()... If you need more room, call 
Button.setMargins(t,l,b,r) ... If you need something more customized, override 
Button.resizeToContents().

A lot of Widgets have resizeToContents or resizeToWidth.

The code is:

   void Button::resizeToContents()
        {
                int w = getFont()->getTextWidth(getText()) +
                        getMargin(SIDE_LEFT) + getMargin(SIDE_RIGHT);
                int h = getFont()->getLineHeight() +
                        getMargin(SIDE_TOP) + getMargin(SIDE_BOTTOM);

                setSize(w,h);

        }
