<a name="GtkCssProvider.description"></a><h2>Description</h2>
<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">$XDG_CONFIG_HOME/gtk-3.0/gtk.css</code> is loaded if it exists. Then, GTK+
loads the first existing file among
<code class="literal">XDG_DATA_HOME/themes/theme-name/gtk-VERSION/gtk.css</code>,
<code class="literal">$HOME/.themes/theme-name/gtk-VERSION/gtk.css</code>,
<code class="literal">$XDG_DATA_DIRS/themes/theme-name/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>

<p>Signals that a parsing error occurred. the <em class="parameter"><code>path</code></em>
, <em class="parameter"><code>line</code></em>
and <em class="parameter"><code>position</code></em>
describe the actual location of the error as accurately as possible.</p>
<p>Parsing errors are never fatal, so the parsing will resume after
the error. Errors may however cause parts of the given
data or even all of it to not be parsed at all. So it is a useful idea
to check that the parsing succeeds by connecting to this signal.</p>
<p>Note that this signal may be emitted at any time as the css provider
may opt to defer parsing parts or all of the input to a later time
than when a loading function was called.</p>
