# api: streamtuner2
# title: Gtk theme setting
# description: Gtk theme switching in Streamtuner2. (Beware of crashes!)
# type: feature
# category: ui
# version: 0.2
# config:
#    { name: theme, type: select, select: "default=default", description: "Theme name" }
#    { name: theme_instant, type: bool, value=0, description: "Activate on the fly." }
# priority: experimental
#
# Brings back the theme switching option - for Gtk2 + Gtk3 now.
#
# Note that not all themes can be loaded on the fly. And may hang
# streamtuner2 even. Most require an application restart still.
# Which is why this is not a built-in feature anymore.
#
# Btw, you could alternatively use GTK2_RC_FILES= or GTK_THEME=
# environment variables for this.
