paintEvent test code to change font weight - fails !
Message 1 in thread
I am trying to 'overload' QPushButton so that - in this test case -
QPushButtons text would be in bold instead of its default normal
however it does not work. My test code is ...
class MyPushButton : public QPushButton
{
public:
MyPushButton(QWidget * parent)
: QPushButton(parent) {}
void paintEvent(QPaintEvent *event)
{
QPainter p(this);
QFont f = p.font();
f.setWeight(QFont::Bold);
p.setFont(f);
QPushButton::paintEvent(event);
}
};
Can anyone tell me where I am going wrong ?
Many thanks
Dave

Constructing a QPainter and setting the font on it doesn't modify the
QPaintEvent* passed to QPushButton::paintEvent(), so the drawing is
unmodified. One tactic that would work is implementing a proxy style,
although it might not be the simplest way.

Why not just set the font on the pushbutton itself?
Ie
MyPushButton( QWidget * parent )
{
QFont f = font();
f.setWeight( Bold )
setFont( f ):
}
