It requires gtk2 to be installed and configured. Beginning with Qt 4.5, this style is included in Qt. This Qt style uses GTK 2 to render all components to blend in with GNOME and similar GTK based environments. Warning: Depending on GTK 2 theme, this style may cause rendering issues such as transparent fonts or inconsistent widgets.

These engines add some extra code in the process and it is arguable that this kind of a solution is not as elegant and optimal as using native styles. Kvantum ( kvantum) is customizable SVG-based theme engine for Qt5 that comes with a variety of built-in styles, including versions of some of popular GTK themes such as Adapta, Arc, Ambiance, Materia.Ī theme engine can be thought of as a thin layer API which translates themes (excluding icons) between one or more toolkits.

For more detailed instructions, see Qt#Configuration of Qt5 apps under environments other than KDE Plasma.

For Qt 5, it can be enabled by setting the following environment variable: QT_STYLE_OVERRIDE=adwaita.

Alternatively, edit the /etc/xdg/nf (system-wide) or ~/.config/nf (user-specific) file:

For Qt4, it can be enabled with Qt Configuration ( qtconfig-qt4), choose adwaita under Appearance > GUI Style.

It can be installed with the adwaita-qt4 AUR and adwaita-qt AUR packages (they both require some time for compiling) for the Qt 4 and 5 versions, respectively. Unlike #QGtkStyle, which mimics the GTK 2 theme, it provides a native Qt style made to look like the GTK 3 Adwaita. adwaita-qt is a Qt port of the Adwaita theme. The GTK 3 version is included in the gtk3 package, while the GTK 2 version is in gnome-themes-extra. Fonts, icon themes, cursors, and widget styles set in System Settings affect GTK settings automatically only the GTK theme should be set manually using the previously mentioned module.Īdwaita is the default GNOME theme.

Gtk 2.0 install#

If running KDE Plasma, install kde-gtk-config and either run it from the command line, or log-out and log-in again and go to System Settings > Appearance > Application Style > Configure GNOME/GTK Application Style…. Once installed, you can use one of the many GTK configuration tools to change the GTK theme. It can be installed with the breeze package for Qt5, the breeze-kde4 AUR package for Qt4, and the breeze-gtk package for GTK 2 and GTK 3. Breezeīreeze is the default Qt style of KDE Plasma. Note: Since version 3.16, GTK 3 does not support non-CSS themes, hence previous solutions such as Oxygen-Gtk are no longer viable options.

With these, you can have one look for all applications regardless of the toolkit they had been written with. There are widget style sets available for the purpose of integration, where builds are written and provided for both Qt and GTK, all major versions included.

Use a special theme engine, which intermediates the modification of the other graphical toolkit to match your main toolkit.

Modify GTK and Qt styles separately with the tools listed below for each toolkit and aim for choosing similarly looking themes (style, colors, icons, cursors, fonts).

Color Theme: A set of global colors that are used in conjunction with the style.

Style: The graphical layout and look of the widget set.

It usually consists of a style, an icon theme and a color theme.

Theme: The custom appearance of an application, widget set, etc.

To get a similar look between the toolkits, you will most likely have to modify the following:

5.7 Dolphin theming does not match Nautilus well.

5.6 kde-gtk-config "System Settings > Application Style > GTK" menu missing.

5.5 GTK apps do not fully use KDE system settings.

5.4 Qt apps run on GNOME Wayland have a non-matching window decoration look, even after setting a Qt theme.

5.3 Flatpak Qt apps do not use Gnome Adwaita dark theme.

Gtk 2.0 upgrade#

5.2 GTK apps do not use svg (breeze) icons after system upgrade.4.3 Improve subpixel rendering of GTK apps under KDE Plasma.4.2 Add Title bar and frame to GTK3 applications under KDE Plasma.
