|
||
<p>GtkCssProvider is an object implementing the <a class="link" href="GtkStyleProvider.html" title="GtkStyleProvider"><span class="type">GtkStyleProvider</span></a> interface.
|
||
It is able to parse <a class="link" href="chap-css-overview.html#css-overview" title="Overview of CSS in GTK+">CSS-like</a> input in order to style widgets.</p>
|
||
<p>An application can make GTK+ parse a specific CSS style sheet by calling
|
||
<a class="link" href="GtkCssProvider.html#gtk-css-provider-load-from-file" title="gtk_css_provider_load_from_file ()"><code class="function">gtk_css_provider_load_from_file()</code></a> or <a class="link" href="GtkCssProvider.html#gtk-css-provider-load-from-resource" title="gtk_css_provider_load_from_resource ()"><code class="function">gtk_css_provider_load_from_resource()</code></a>
|
||
and adding the provider with <a class="link" href="GtkStyleContext.html#gtk-style-context-add-provider" title="gtk_style_context_add_provider ()"><code class="function">gtk_style_context_add_provider()</code></a> or
|
||
<a class="link" href="GtkStyleContext.html#gtk-style-context-add-provider-for-screen" title="gtk_style_context_add_provider_for_screen ()"><code class="function">gtk_style_context_add_provider_for_screen()</code></a>.</p>
|
||
<p>In addition, certain files will be read when GTK+ is initialized. First, the
|
||
file <code class="literal">$XDG_CONFIG_HOME/gtk-3.0/gtk.css</code> is loaded if it exists. Then, GTK+
|
||
loads the first existing file among
|
||
<code class="literal">XDG_DATA_HOME/themes/THEME/gtk-VERSION/gtk.css</code>,
|
||
<code class="literal">$HOME/.themes/THEME/gtk-VERSION/gtk.css</code>,
|
||
<code class="literal">$XDG_DATA_DIRS/themes/THEME/gtk-VERSION/gtk.css</code> and
|
||
<code class="literal">DATADIR/share/themes/THEME/gtk-VERSION/gtk.css</code>, where <code class="literal">THEME</code> is the name of
|
||
the current theme (see the <a class="link" href="GtkSettings.html#GtkSettings--gtk-theme-name" title="The “gtk-theme-name” property"><span class="type">“gtk-theme-name”</span></a> setting), <code class="literal">DATADIR</code>
|
||
is the prefix configured when GTK+ was compiled (unless overridden by the
|
||
<code class="literal">GTK_DATA_PREFIX</code> environment variable), and <code class="literal">VERSION</code> 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.</p>
|
||
<p>In the same way, GTK+ tries to load a gtk-keys.css file for the current
|
||
key theme, as defined by <a class="link" href="GtkSettings.html#GtkSettings--gtk-key-theme-name" title="The “gtk-key-theme-name” property"><span class="type">“gtk-key-theme-name”</span></a>.</p>

to check that the parsing succeeds by connecting to this signal.</p>
