MhM93

in the qrc.
in this code the picture is not set for main window background :(this is my code in my css exactly)

/*========================================*/
/*     QWidget - QDialog       */

QWidget , QDialog
{
	background-color:rgb(67,67,67);
}

#MainWindow
{
	background-image: url(":/myImg/1.jpg");
}

@MhM93
then you need to prepend : or qrc:// to your path.

MhM93

I set ": " and " . but the result is not change.

@MhM93
i don't know your qrc file, so i don't know if that path is correct.
What does the following return?

qDebug() << QFile::exists(":/myImg/1.jpg");

Hi,
you @MhM93 use background-image but @raven-worx proposes to use background. Maybe this is essential.

Hi,
@raven-worx , thanks for reply.

qDebug() << QFile::exists(":/myImg/1.jpg");

this code return true;
@m-sue : thanks for reply. I change my code to this. but the picture is not set the background in mainwindow:

QWidget , QDialog
{
	background-color:rgb(67,67,67);
}

#MainWindow
{
	background: url(:/myImg/1.jpg);
}

@MhM93
and now pls try to set it exactly to this:

QWidget , QDialog
{
	background: rgb(67,67,67);
}

#MainWindow
{
	background: url(':/myImg/1.jpg');
}

But most probably you wont see the image because you set it to the main window directly. And it's central widget is covering over it, since you also set a background color for all QWidgets.

MhM93

really thanks @raven-worx for reply. I change the css to this:

QWidget , QDialog
{
	background:rgb(67,67,67);
}

#MainWindow
{
	background: url(:/myImg/1.jpg);
}

all widget set dark, but the picture is not set in the main window background.
:(

@MhM93
did you read my note at the end of my last post?

MhM93

so how can I do some thong like that? I want to set back ground image for some widget and the other widget i like to be dark. How can I do that?

raven-worx

@MhM93
as i already said. Don't apply the background-image to the main-window but to the widget you set as central widget...

MhM93

Do you mean I set the main window central widget for set back ground image?could you give me example?
So sorry I am beginner in qt(also in English) so sorry :">

raven-worx

@MhM93
CSS:

QWidget , QDialog
{
	background:rgb(67,67,67);
}

#MyCentralWidget
{
	background: url(:/myImg/1.jpg);
}

CPP:

QFrame* centralWidget = new QFrame;
centralWidget->setObjectName("MyCentralWidget");
mainWindow->setCentralWidget( centralWidget );

MhM93

really thanks. now I get it. you mean I set the frame for central widget in the main window and set the picture for it.
thanksss .
