Is it possible to set a background image to a widget?

kamalakshantv

I had tried it but the background image was not getting displayed. Can you provide the syntax for adding a background image to a QWidget.

genjix

setStyleSheet("background-image: ./image.png");

I thik this one will fit better
@
qApp->setStyleSheet("QWidget {background-image: url(./image.png) }");
@

and if you just want the background on a particular widget use:
@myWidget->setStyleSheet("background-image: url(./image.png)")@

Thank you, I had tried the same before also and then it was not working - now its working. May be I had not built it properly or did some silly mistake then.

I am applying the below style using Qt Designer on the root widget

QWidget {background-image: url(./image.png) }

Now in this case all the child widgets also have the same image as background image. How to modify the above to have it only configured as a background image to the root widget.

Give name to your widget by setObjectname().

eg:
@
QPushButton *okButton = new QPushButton;
okButton->setObjectname(QObject::tr(okButton));
@
in stylesheet,
@
QPushButton#okButton
{
color: gray
}
@
now only okButton will be gray.

Same thing is applicable in your case. Hope it helps!

Please also check out the docs for style sheets at:
"http://doc.qt.nokia.com/4.7/stylesheet.html":http://doc.qt.nokia.com/4.7/stylesheet.html

houmingc

MainWindow w;
w.setStyleSheet("background-image:url(./file/left.png)");
w.show();

I did setStyleSheet on MainWindow, it doesn't seem to work

Francknos

MainWindow w; w.setStyleSheet(“background-image:url(:/file/left.png)”); w.show();
WITH ::::::: and if you have a ui file. put setStyleSheet after ui->setupUI(this);

i have left.png and right.png in my resource folder under /file
which is the correct command?

houmingc

@
Error:Could not parse stylesheet of object 0xbfdb6220
ui->setupUi(this);
setStyleSheet("background-image:url(:/left.png;"
"background-repeat:no-repeat;");

Your style sheet code is wrong, you are missing a closing parenthesis.

I think the link below can solve the problem but i can't access my jpg in resources file.

palette->setBrush(QPalette::Background,(new QBrush((new QPixmap(":/1.jpg")))));
