Freedesktop icons

[N.A.Y.]

I'm writing a program for Razor-Qt and want to use standard icons like edit-undo, edit-cut, application-exit, etc. But oxygen icons theme isn't loaded in Razor-Qt just in KDE or Gnome. My program loads hicolor icon theme. I found the way: I load ~/.config/razor/razor.conf and read icon_theme parameter, but this is a hack. I cannot use this method for other Qt applications. A want to use some standard method. Maybe, Qt can load freedesktop icons theme value. But there is it? I know you are using my method for load current theme. I have read Qt sources, but there is no answer.

From "src/gui/kernel/qguiplatformplugin.cpp":

/* the default icon theme name for QIcon::fromTheme. */

QString QGuiPlatformPlugin::systemIconThemeName()

{

    QString result;

#ifdef Q_WS_X11

    if (X11->desktopEnvironment == DE_GNOME) {

        result = QString::fromLatin1("gnome");

#ifndef QT_NO_STYLE_GTK

        result = QGtkStylePrivate::getGConfString(QLatin1String("/desktop/gnome/interface/icon_theme"), result);

#endif

    } else if (X11->desktopEnvironment == DE_KDE) {

        result =  X11->desktopVersion >= 4 ? QString::fromLatin1("oxygen") : QString::fromLatin1("crystalsvg");

        QSettings settings(QKde::kdeHome() + QLatin1String("/share/config/kdeglobals"), QSettings::IniFormat);

        settings.beginGroup(QLatin1String("Icons"));

        result = settings.value(QLatin1String("Theme"), result).toString();

    }

#endif

    return result;

}

 Thanks.

yes. This is real problem. There is no common standard for it (as I know). I can create a patch for Qt with one more else if (de==razor) but I don't think it's the correct solution...

I had a theme-config-spec proposal but it was rejected by the GTK guys. Apparently, the next solution is for Qt to implement getting theme config from xsettings.

Fucking GTK+ guys.. make unhappy the life of programers..

Doesn't QIcon::fromTheme() handle this?

Cheers,

Their reasoning made a lot of sense which is why I did not insist on my spec. Reasoning being that setting *storage* should not be absolute to files. xsettings provides a transient storage for themes and fallback themes which is completely fine. Additionally, if Qt starts supporting it, it'll also be supported by Gtk automatically. It's a good solution, however a dev needs to step up to implement it -- I would do it in a heartbeat but I'm a python programmer, not C++.

The issue with ::fromTheme is that it only looks in KDE settings, and/or assumes "oxygen" depending on the DE, then falls back to hicolor, so we cannot rely on it as it is.
