Applying StyleSheet to Custom Window

[andre]

Styling a custom widget through style sheets is not supported. Sorry.

Edit:
Well, let me specify that a bit: custom drawn custom widgets can not be styled using qss. You can use qss to style custom widgets that are just compositions of existing Qt widgets.

[Thibaut]

By custom drawn widget, you do mean widgets inherited from Qwidget, right ?

Are you aware of any plan to implement this in a next version ?

[andre]

Me? No, not me. I don't work for Nokia :-)

What I mean by custom drawn, are widgets that are based directly on QWidget and where you implement paintEvent() do do your own painting yourself.

[giesbert]

If you just derive from QWidget and need that one styled, you have to do some stuff :-)

@
void TitiWidget::paintEvent(QPaintEvent* /p_pEvent/)
{
QStyleOption opt;
opt.init(this);
QStylePainter p(this);
p.drawPrimitive(QStyle::PE_Widget, opt);
}
@

why not in the constructor of TitiWidget put this ?

@
setStyleSheet(
"border: 2px solid green;"
"border-radius: 20px;"
"padding: 2px;"
"background-color: rgb(85, 85, 255);"
);@

Because it all depends on how TitiWidget is implemented if this is going to work or not.

[giesbert]

It only works if you overwrite the paint event.
Otherwise nothing happens.

Thanks a lot for your answers.

The

QStylePainter p(this);

}

trick works just fine. And it's actually in Qt's documentation. Shame on me.

Edit: please use code tags (@) before and after your code section; Andre

Nice trick to get at least the basic style sheet stuff painted correctly, but I still don't see a way to get where you can draw, let alone a way to style what you draw yourself using that style sheet...

[giesbert]

That does not work at all. If you have a custom drawn widget, it can't be styled. Only if you do some basic style sheet stuff and paint on it later...
