How do I access / load icon in QtCreator ? From "theme path" to " theme name "?

Anonymous_Banned275

Here is my sample code to access "New" icon.

const QIcon newIcon = QIcon::fromTheme("document-new", QIcon(":/images/new.png"));

I am looking for basic bluetooth icon.
I know it exists in my system as "bluetooth.png".

I can retrieve "theme" path

  qDebug() << QIcon::themeSearchPaths();

How do I get form "theme path" to " theme name "?
Or do I have to ?

QIcon RTFM is not much help.

THANKS

Freedesktop specification does not specify any icons for Bluetooth. So getting one through fromTheme() will not work.

Looking through KDE code for bluedevil, I noticed these:

    if (deviceConnected) {
        return "preferences-system-bluetooth-activated";
    } else if (!btManager.bluetoothOperational) {
        return "preferences-system-bluetooth-inactive";
    }
    return "preferences-system-bluetooth";

I have no idea if it will work, but it might be worth a try.

@sierdzio Thanks.
It looks as I could do this the "create your own icon" way so I can reuse existing QIcon code.

I found few python code examples

Basically use any "bluetooth.png" icon currently on my system.

Still looking for some explanation why I need "theme".
It looks as they are using "theme" as some kind of "chapter"... or directory.

Basically - if I am looking for an icon to represent a "bullet train" - how do I correlate that to "theme"?

I don't understand the why you mention theme name at all, sorry. "fromTheme" simply means "give me an icon from system theme" or "give me a standard system icon". The method returns an icon (ready to use), not path - there is no need to convert icon to theme or anything like that. Or I'm missing your point.
