Drawing rectangles on a QSystemTrayIcon
Message 1 in thread
Hello!
Thanks to the suggestions you provided, i realized the printing
of a rectangle over the icon of the QSystemTray object.
The code that realizes this is as follows:
QPixmap pix(ICON_PATH + "ipfire.png");
QPainter painter(&pix);
if(refresh_no % 5 > 3)
{
QRectF rect(0, actualw, actualw/2, -30);
painter.drawRect(rect);
painter.fillRect(rect, QBrush(KGREEN, Qt::Dense5Pattern));
}
else
{
QRectF rect(0, actualw, actualw/2, -15);
painter.drawRect(rect);
painter.fillRect(rect, QBrush(KGREEN, Qt::Dense6Pattern));
}
QIcon newicon = QIcon(pix);
setIcon(newicon);
at a certain timeout of a QTimer the pixmap is modified and set again
with setIcon().
The problem is that the icon flickers sometimes when it gets
repainted, and i would like
to avoid this.
Is there anything i can do/modify to achieve a stable picture on the
sistem tray?
Thank you.
Giacomo
