QMainWindow Problem

[Ketan Shah]

In my application there are 3 windows: One Main Window, and two child windows.
I am changing my main windows background color to white using setstylesheet..
so this is also applying the same settings to my child windows, which I dont want..
In one of my child windows there is a listview with scrollbar, they are also becoming white.
so my question is how can I change my two child windows background settings to their default settings.

Thanx in advance..

Please post your style sheet, how you set it and how you create your widgets. Somewhere in that, I assume, area is the bug.

@myWindow->setStyleSheet(QString::fromUtf8("background-color: rgb(254, 255, 247);"));@

@extension *e = new extension(this);
e->setWindowModality(Qt::WindowModal);
e->show();

a = new ampstart(this);
a->setWindowModality(Qt::WindowModal);
a->show();
@

above is the way how I created my stylesheet, and the two child windows..

You need to use a more specific selector to ensure that only your QMainWindow selects that particular syle.

Something like this stylesheet snippet should do it:

@
QMainWindow {
background-color: rgb(254, 255, 247);
}
@

You can set this directly on yoru mainwindow via the ui file. Just right-click on the main window in design mode of creator and select "Change Stylesheet..." and past the above in and hit Apply.

Yes, I agree with ZapB but I have one comment about the two child windows.
It is not necessary to call show() explicitly for each child as they will be show when the parent window is visible.

The reason why this is needed is that style sheets are also derived / forwarded to shildren. And you set the properties in a generic way.
