The appearance of gtk (Gnome) applications under KDE is controlled by a System Settings function: System Settings->Application Appearance->GTK+ Appearance->Widget Style which works as advertised: the theme chosen for the widget style affects Gnome applications (in particular evolution), changing the shape and color of the scrollbars, color of selected portions of text, etc. The themes appear to be a selection of the themes available in /usr/share/themes, but only a very partial selection. /usr/share/themes contains 29 themes, of which only 9 are available in the pull-down menu next to Widget Style. How can the remaining themes in the system be made available to KDE? Is it possible to download more GTK+ themes for use by KDE, or are only some themes compatible. System is Fedora-20 with all upgrades running on x86_64 hardware. The problem arose because since upgrading to Fedora-20, evolution under the KDE desktop doesn't look good. The selected message isn't highlighted much. Thanks - jon
