set stylesheet for qfiledialog

[alizadeh91]

Is there any way to set stylesheet for QFileDialog?

[Santosh Reddy]

Yes, just like any other custom widget.
Just an example

QFileDialog dialog;
dialog.setStyleSheet("QPushButton { background-color: red }");
dialog.show();

QFileDialog dialog;
dialog.setStyleSheet("QPushButton { background-color: red }");
dialog.show();

To copy to clipboard, switch view to plain text mode

Thanks for reply, Yes that worked but when i use it this way:

QFileDialog fd;
    fd.setStyleSheet("QPushButton { background-color: red }");
    fd.getSaveFileName(0);

QFileDialog fd;
    fd.setStyleSheet("QPushButton { background-color: red }");
    fd.getSaveFileName(0);

To copy to clipboard, switch view to plain text mode 

the style is gone! what happens?

getSaveFileName() is a static call, and will by default create a native file dialog, which will not care about stylesheets. You can do this way.

Force use of non-native file dialogs, but only way to apply stylehseet is to apply on the parent (if dialog does not have a parent, you can apply on the applcation, but be warned about the glabal application of styles.

qApp->setStyleSheet("QPushButton { background-color: red }");
QFileDialog::getSaveFileName(0, QString(), QString(), QString(), 0, QFileDialog::DontUseNativeDialog);

qApp->setStyleSheet("QPushButton { background-color: red }");
QFileDialog::getSaveFileName(0, QString(), QString(), QString(), 0, QFileDialog::DontUseNativeDialog);
