Hi all,
in our application we're setting the window title for dock widgets via
QWidget::setWindowTitle() like in

On windows and on macOs additional ampersand is shown in the title text

Hi,
I need to fix the size of a QListView to three items aligned vertically as on

Hi Tony,

no, this somehow completely blocked the resize... Calling updateGeometry()
solved this problem.

Works now. I pushed a modified version of your code to our repository in
https://cgit.kde.org/labplot.git/commit/?
id=1cacf9f095b5e850baa58584b071986fbfe790fb
The only problem now is that the entered text is not shown in TextEdit with
this new class.

Thanks Igor, I've got the idea. The resize works fine now but I have the

one frequently sees form text fields on the web where the actual text field can

In a read-only QTextEdit a CTRL+C event seems to be "converted" to a close

Hi,
in Qt5 we have http://doc.qt.io/qt-5/qstandardpaths.html#findExecutable . Is
there something similar available in Qt 4.8, too? Can somebody point me to the
proper static function?

Actually, without painter.setRenderHint(QPainter::SmoothPixmapTransform,
true); the quality is even worser... But I don't really understand why this
render hint has an effect at all.

You're right. I really used screenPos instead of scenePos at one place...
Thank you for the hint!

Hi,
I'm having here a problem with mapFrom/mapTo-functions. In a class derived
from QGraphicsItem I override mousePressEvent and I get for
mapFromScreen(event->screenPos()) a point that is different from event->pos().
Similarly, mapToScreen(event->pos()) doesn't lead to event->screenPos(). Why?

I guess, you'll have to combine translation and rotation and to somehow
provide your own QMatrix4x4 to QGraphicsItem...

Strange. What kind of errors do you get if you try to compile the debug
