Struct gtk::CssProvider[][src]

pub struct CssProvider(_);
Expand description

GtkCssProvider is an object implementing the StyleProvider interface. It is able to parse [CSS-like][css-overview] input in order to style widgets.

An application can make GTK+ parse a specific CSS style sheet by calling CssProviderExt::load_from_file() or CssProviderExt::load_from_resource() and adding the provider with StyleContextExt::add_provider() or StyleContext::add_provider_for_screen().

In addition, certain files will be read when GTK+ is initialized. First, the file $XDG_CONFIG_HOME/gtk-3.0/gtk.css is loaded if it exists. Then, GTK+ loads the first existing file among XDG_DATA_HOME/themes/THEME/gtk-VERSION/gtk.css, $HOME/.themes/THEME/gtk-VERSION/gtk.css, $XDG_DATA_DIRS/themes/THEME/gtk-VERSION/gtk.css and DATADIR/share/themes/THEME/gtk-VERSION/gtk.css, where THEME is the name of the current theme (see the property::Settings::gtk-theme-name setting), DATADIR is the prefix configured when GTK+ was compiled (unless overridden by the GTK_DATA_PREFIX environment variable), and VERSION is the GTK+ version number. If no file is found for the current version, GTK+ tries older versions all the way back to 3.0.

In the same way, GTK+ tries to load a gtk-keys.css file for the current key theme, as defined by property::Settings::gtk-key-theme-name.

Implements

CssProviderExt, glib::ObjectExt, StyleProviderExt

Implementations

Returns a newly created CssProvider.

Returns

A new CssProvider

Returns the provider containing the style settings used as a fallback for all widgets.

Deprecated since 3.24

Use new() instead.

Returns

The provider used for fallback styling. This memory is owned by GTK+, and you must not free it.

Loads a theme from the usual theme paths

name

A theme name

variant

variant to load, for example, “dark”, or None for the default

Returns

a CssProvider with the theme loaded. This memory is owned by GTK+, and you must not free it.
