This is a Qt style which intends to make applications blend perfectly into the GNOME desktop environment by using GTK to render all components. To use this style you must have at least GTK+ 2.0 and Qt 4.3, although Qt 4.4 or higher is preferred.Having trouble making your Qt applications use QGtkStyle?
Qt won't apply QGtkStyle correctly if GTK is using the GTK-QT-Engine. Qt determines whether the GTK-QT-Engine is in use by reading the GTK configuration files listed in the environmental variable GTK2_RC_FILES. If the environmental variable is not set properly, Qt assumes you are using the GTK-QT-Engine, sets QGtkStyle to use the style GTK style Clearlooks, and outputs an error message:
QGtkStyle cannot be used together with the GTK_Qt engine.
Users of Openbox and other non-GNOME environments may encounter this probem. Here is a solution:
- Tell Qt where to look for your GTK configuration file by adding the following to your .xinitrc file:
- To add multiple paths, separate them with colons.
- The $HOME part will expand to be path to your user's home directory. Using the ~ shortcut won't work.
- In .gtkrc-2.0 you must specify a GTK theme. For example:
- This is usually done for you by an application which sets GTK2 Styles
However it seems in sume cases those tools insert only an include directive like
...which apparently is not recognized by all versions of QGtkStyle. You can hotfix this problem by inserting the gtk-theme-name manually in your .gtkrc-2.0 like above, note however that Gtk2-style-change applications might overwrite that change when you use them.
To choose your GTK theme for QT apps you must run:
