public enum SettingsSignalName : String, SignalNameProtocol

Undocumented

  • The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

    Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in notify being emitted, even if the new value is the same as the old. If they did pass G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

    This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

    (C Language Example):

    g_signal_connect (text_view->buffer, "notify::paste-target-list",
                  G_CALLBACK (gtk_text_view_target_list_notify),
                  text_view)

    It is important to note that you must use canonical parameter names as detail strings for the notify signal.

  • Whether the application prefers to use a dark theme. If a GTK+ theme includes a dark variant, it will be used instead of the configured theme.

    Some applications benefit from minimizing the amount of light pollution that interferes with the content. Good candidates for dark themes are photo and video editors that make the actual content get all the attention and minimize the distraction of the chrome.

    Dark themes should not be used for documents, where large spaces are white/light and the dark chrome creates too much contrast (web browser, text editor…).

    Declaration

    Show on GitHub

  • A palette of named colors for use in themes. The format of the string is

    name1: color1
name2: color2
...

    Color names must be acceptable as identifiers in the gtkrc syntax, and color specifications must be in the format accepted by gdk_color_parse().

    Note that due to the way the color tables from different sources are merged, color specifications will be converted to hexadecimal form when getting this property.

    Starting with GTK+ 2.12, the entries can alternatively be separated by ‘;’ instead of newlines:

    name1: color1; name2: color2; ...

    gtk-color-scheme is deprecated: Color scheme support was dropped and is no longer supported. You can still set this property, but it will be ignored.

  • This setting determines which buttons should be put in the titlebar of client-side decorated windows, and whether they should be placed at the left of right.

    The format of the string is button names, separated by commas. A colon separates the buttons that should appear on the left from those on the right. Recognized button names are minimize, maximize, close, icon (the window icon) and menu (a menu button for the fallback app menu).

    For example, “menu:minimize,maximize,close” specifies a menu on the left, and minimize, maximize and close buttons on the right.

    Note that buttons will only be shown when they are meaningful. E.g. a menu button only appears when the desktop shell does not show the app menu, and a close button only appears on a window that can be closed.

    Also note that the setting can be overridden with the GtkHeaderBar:decoration-layout property.
