[SOLVED] Change background color of QToolBar doesn't work in Linux

[Bambo]

Hi,
i have this simply code in Linux (xubuntu):
@MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent)
{
mainToolBar = new QToolBar;
mainToolBar->setAutoFillBackground(true);
mainToolBar->setStyleSheet("QToolBar { background: yellow; }");

addToolBar(Qt::TopToolBarArea, mainToolBar);

}@

if toolbar is in Top, the background color is default
if toolbar is in Left, the background color is yellow
why?
how can i change color of Top QToolBar?

(in windows it works correct)

Thanks for reply.

Hi Bambo

please, always tell us which version of Qt did you use and which linux distribution.

I did a quick test and it worked under Qt 4.7.0 with ubuntu 10.10

BTW mainToolBar->setAutoFillBackground(true); is not necessary if you work with stylesheet.
It is only neccessary when you are working with QPalette.

Cheers

Hi Messi,
I use:

• Qt 5.0.0
• Xubuntu 12.10

I try it also under Qt 4.8.x, Ubuntu 12.10 and it doesn't work too.

Could you try this ? I'm not sure background provides the exact same behavior as background-color.
@
QToolBar {
background-color: yellow;
}

Ok I can verify that the example is not working under Lubuntu 12.4 qith Qt4.8.1, 4.8.3 and 5.0.0.
What I can see is when I move the toolbar around and redock it then i can see the yellow color for a split second.
When I don't add it to the MainWindow it works.

It seems to me that the stylesheet of the toolbar will be overwritten by the MainWindow.

Normally, your QSS rule would be overwritten only if you have more specific rules (#name, ::pseudo-state) in parents widgets. A possible explaination would be that the original style isn't fully overwritten.

You could then try to add the following rule to force a deeper re-styling:
@
border: 1px solid black;
@

Also check background-color.
