<a name="GtkStyleContext.description"></a><h2>Description</h2>
<p><a class="link" href="GtkStyleContext.html" title="GtkStyleContext"><span class="type">GtkStyleContext</span></a> is an object that stores styling information affecting
a widget defined by <a class="link" href="gtk3-GtkWidgetPath.html#GtkWidgetPath" title="GtkWidgetPath"><span class="type">GtkWidgetPath</span></a>.</p>
<p>In order to construct the final style information, <a class="link" href="GtkStyleContext.html" title="GtkStyleContext"><span class="type">GtkStyleContext</span></a>
queries information from all attached <a href="GtkStyleProvider.html#GtkStyleProvider-struct"><span class="type">GtkStyleProviders</span></a>. Style providers
can be either attached explicitly to the context through
<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 to the screen through
<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>. The resulting style is a
combination of all providers’ information in priority order.</p>
<p>For GTK+ widgets, any <a class="link" href="GtkStyleContext.html" title="GtkStyleContext"><span class="type">GtkStyleContext</span></a> returned by
<a class="link" href="GtkWidget.html#gtk-widget-get-style-context" title="gtk_widget_get_style_context ()"><code class="function">gtk_widget_get_style_context()</code></a> will already have a <a class="link" href="gtk3-GtkWidgetPath.html#GtkWidgetPath" title="GtkWidgetPath"><span class="type">GtkWidgetPath</span></a>, a
<a href="http://developer.gnome.org/gdk3/GdkScreen.html#GdkScreen-struct"><span class="type">GdkScreen</span></a> and RTL/LTR information set. The style context will also be
updated automatically if any of these settings change on the widget.</p>
<p>If you are using the theming layer standalone, you will need to set a
widget path and a screen yourself to the created style context through
<a class="link" href="GtkStyleContext.html#gtk-style-context-set-path" title="gtk_style_context_set_path ()"><code class="function">gtk_style_context_set_path()</code></a> and <a class="link" href="GtkStyleContext.html#gtk-style-context-set-screen" title="gtk_style_context_set_screen ()"><code class="function">gtk_style_context_set_screen()</code></a>, as well
as updating the context yourself using <a class="link" href="GtkStyleContext.html#gtk-style-context-invalidate" title="gtk_style_context_invalidate ()"><code class="function">gtk_style_context_invalidate()</code></a>
whenever any of the conditions change, such as a change in 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 or a hierarchy change in the rendered
widget. See the “Foreign drawing“ example in gtk3-demo.</p>
<div class="refsect2">
<a name="gtkstylecontext-classes"></a><h3>Style Classes</h3>
<p>Widgets can add style classes to their context, which can be used to associate
different styles by class. The documentation for individual widgets lists
which style classes it uses itself, and which style classes may be added by
applications to affect their appearance.</p>
<p>GTK+ defines macros for a number of style classes.</p>
</div>
<hr>
<div class="refsect2">
<a name="id-1.5.4.10.7"></a><h3>Style Regions</h3>
<p>Widgets can also add regions with flags to their context. This feature is
deprecated and will be removed in a future GTK+ update. Please use style
classes instead.</p>
<p>GTK+ defines macros for a number of style regions.</p>

<a name="id-1.5.4.10.8"></a><h3>Custom styling in UI libraries and applications</h3>
<p>If you are developing a library with custom <a href="GtkWidget.html#GtkWidget-struct"><span class="type">GtkWidgets</span></a> that
render differently than standard components, you may need to add a
<a class="link" href="GtkStyleProvider.html" title="GtkStyleProvider"><span class="type">GtkStyleProvider</span></a> yourself with the <a class="link" href="GtkStyleProvider.html#GTK-STYLE-PROVIDER-PRIORITY-FALLBACK:CAPS" title="GTK_STYLE_PROVIDER_PRIORITY_FALLBACK"><code class="literal">GTK_STYLE_PROVIDER_PRIORITY_FALLBACK</code></a>
priority, either a <a class="link" href="GtkCssProvider.html" title="GtkCssProvider"><span class="type">GtkCssProvider</span></a> or a custom object implementing the
<a class="link" href="GtkStyleProvider.html" title="GtkStyleProvider"><span class="type">GtkStyleProvider</span></a> interface. This way themes may still attempt
to style your UI elements in a different way if needed so.</p>
<p>If you are using custom styling on an applications, you probably want then
to make your style information prevail to the theme’s, so you must use
a <a class="link" href="GtkStyleProvider.html" title="GtkStyleProvider"><span class="type">GtkStyleProvider</span></a> with the <a class="link" href="GtkStyleProvider.html#GTK-STYLE-PROVIDER-PRIORITY-APPLICATION:CAPS" title="GTK_STYLE_PROVIDER_PRIORITY_APPLICATION"><code class="literal">GTK_STYLE_PROVIDER_PRIORITY_APPLICATION</code></a>
priority, keep in mind that the user settings in
<code class="literal">XDG_CONFIG_HOME/gtk-3.0/gtk.css</code> will
still take precedence over your changes, as it uses the
<a class="link" href="GtkStyleProvider.html#GTK-STYLE-PROVIDER-PRIORITY-USER:CAPS" title="GTK_STYLE_PROVIDER_PRIORITY_USER"><code class="literal">GTK_STYLE_PROVIDER_PRIORITY_USER</code></a> priority.</p>

can be an image, or a gradient, or any other pattern including solid colors.</p>

achieve this result is to use <a class="link" href="GtkStyleContext.html#gtk-render-background" title="gtk_render_background ()"><code class="function">gtk_render_background()</code></a> instead, along with CSS
style classes to modify the color to be rendered.</p>

<div class="warning"><p><code class="literal">gtk_style_context_add_region</code> has been deprecated since version 3.14 and should not be used in newly-written code.</p></div>
<p>Adds a region to <em class="parameter"><code>context</code></em>
, so posterior calls to
<a class="link" href="GtkStyleContext.html#gtk-style-context-get" title="gtk_style_context_get ()"><code class="function">gtk_style_context_get()</code></a> or any of the gtk_render_*()
functions will make use of this new region for styling.</p>
<p>In the CSS file format, a <a class="link" href="GtkTreeView.html" title="GtkTreeView"><span class="type">GtkTreeView</span></a> defining a “row”
region, would be matched by:</p>
<div class="informalexample">
<table class="listing_frame" border="0" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td class="listing_lines" align="right"><pre>1</pre></td>
<td class="listing_code"><pre class="programlisting">GtkTreeView row <span class="gtkdoc opt">{ ... }</span></pre></td>
</tr>
</tbody>
</table>
</div>
<p></p>
<p>Pseudo-classes are used for matching <em class="parameter"><code>flags</code></em>
, so the two
following rules:</p>
<div class="informalexample">
<table class="listing_frame" border="0" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td class="listing_lines" align="right"><pre>1
2</pre></td>
<td class="listing_code"><pre class="programlisting">GtkTreeView row<span class="gtkdoc opt">:</span>nth<span class="gtkdoc opt">-</span><span class="function">child</span><span class="gtkdoc opt">(</span>even<span class="gtkdoc opt">) { ... }</span>
GtkTreeView row<span class="gtkdoc opt">:</span>nth<span class="gtkdoc opt">-</span><span class="function">child</span><span class="gtkdoc opt">(</span>odd<span class="gtkdoc opt">) { ... }</span></pre></td>
</tr>
</tbody>
</table>
</div>
<p></p>
<p>would apply to even and odd rows, respectively.</p>
<p>Region names must only contain lowercase letters
and “-”, starting always with a lowercase letter.</p>
