Getting the name of the default style

[gregsan]

Hi,

I have a question regarding the default style name for a given operating system.

I would like to show in my app a combobox with all valid styles (which I can get using QStyleFactory.keys()) and select the style that is the default one for the operating system on which the app is run.

How do I get the default style name?

I already tried the QSettings("Trolltech").value("style"), but the string that I got is empty.

If it's important, I'm using Qt 4.3.3 thru PyQt.

Thanks in advance for the answer...

You mean style Name: Motif/CDE/ etc ?

In C++ it would be:

QString styleName = QApplication::style()->objectName();

QString styleName = QApplication::style()->objectName();

To copy to clipboard, switch view to plain text mode

It is an old thread but nevertheless interesting for my identical task.

There is one thing that does not work for me (Qt 4.7.4):
What jpn suggests return the current style of the application.
But I need the default style an application gets if the style is not manually changed. On WinXP it should return "WindowsXP", on Vista it should return something like "WindowsVista" (I assume).

I need this for configuring my application to "system default style" instead of a manually selected style like WindowsXP, Cleanlooks or...

(Edit of my previous post is not possible, so this "double post")

What I am doing now to get the "default style" is to ask the QApplication object right after application start for its style before applying a different style.

QString defaultStyleName = qApp->style()->objectName();
qApp->setStyle(/*e.g. Plastique style*/);
 
// much more code follows and later I want to switch to the default style:
qApp->setStyle(QStyleFactory::create(defaultStyleName));

QString defaultStyleName = qApp->style()->objectName();
qApp->setStyle(/*e.g. Plastique style*/);

// much more code follows and later I want to switch to the default style:
qApp->setStyle(QStyleFactory::create(defaultStyleName));

To copy to clipboard, switch view to plain text mode 

But this approach fails if someone start teh application with the commandline option -style=<someStyle>. Then my defaultStyleName string would be <someStyle> and NOT the default style Qt uses for the underlaying operating system.

How can the system's default style be determined?
