<para id="style-properties">
<structname>GtkWidget</structname> introduces <firstterm>style 
properties</firstterm> - these are basically object properties that are stored
not on the object, but in the style object associated to the widget. Style
properties are set in <link linkend="gtk-Resource-Files">resource files</link>.
This mechanism is used for configuring such things as the location of the
scrollbar arrows through the theme, giving theme authors more control over the
look of applications without the need to write a theme engine in C.

<para>
Use gtk_widget_class_install_style_property() to install style properties for 
a widget class, gtk_widget_class_find_style_property() or
gtk_widget_class_list_style_properties() to get information about existing
style properties and gtk_widget_style_get_property(), gtk_widget_style_get() or
gtk_widget_style_get_valist() to obtain the value of a style property.

<refsect2 id="GtkWidget-BUILDER-UI">
<title>GtkWidget as GtkBuildable</title>
<para>
The GtkWidget implementation of the GtkBuildable interface supports a 
custom &lt;accelerator&gt; element, which has attributes named key, 
modifiers and signal and allows to specify accelerators.
</para>
<example>
<title>A UI definition fragment specifying an accelerator</title>
<programlisting><![CDATA[
<object class="GtkButton">
  <accelerator key="q" modifiers="GDK_CONTROL_MASK" signal="clicked"/>
</object>
]]></programlisting>
</example>
In addition to accelerators, <structname>GtkWidget</structname> also support a 
custom &lt;accessible&gt; element, which supports actions and relations. 
Properties on the accessible implementation of an object can be set by accessing the 
internal child "accessible" of a <structname>GtkWidget</structname>.
<example>
<title>A UI definition fragment specifying an accessible</title>
<programlisting><![CDATA[
<object class="GtkButton" id="label1"/>
  <property name="label">I am a Label for a Button</property>
</object>
<object class="GtkButton" id="button1">
  <accessibility>
    <action action_name="click" description="Click the button."/>
    <relation target="label1" type="labelled-by"/>
  </accessibility>
  <child internal-child="accessible">
    <object class="AtkObject" id="a11y-button1">
      <property name="AtkObject::name">Clickable Button</property>
    </object>

<!-- ##### ENUM GtkWidgetFlags ##### -->
<para>
Tells about certain properties of the widget.
</para>

@GTK_TOPLEVEL: 
        widgets without a real parent, as there are #GtkWindow<!-- -->s and
        #GtkMenu<!-- -->s have this flag set throughout their lifetime.
        Toplevel widgets always contain their own #GdkWindow.
@GTK_NO_WINDOW: 
        Indicative for a widget that does not provide its own #GdkWindow. 
        Visible action (e.g. drawing) is performed on the parent's #GdkWindow.
@GTK_REALIZED: 
        Set by gtk_widget_realize(), unset by gtk_widget_unrealize().
        A realized widget has an associated #GdkWindow.
@GTK_MAPPED: 
        Set by gtk_widget_map(), unset by gtk_widget_unmap().
        Only realized widgets can be mapped. It means that gdk_window_show() 
        has been called on the widgets window(s).
@GTK_VISIBLE: 
        Set by gtk_widget_show(), unset by gtk_widget_hide(). Implies that a 
        widget will be mapped as soon as its parent is mapped.
@GTK_SENSITIVE: 
        Set and unset by gtk_widget_set_sensitive().
        The sensitivity of a widget determines whether it will receive
        certain events (e.g. button or key presses). One premise for
        the widget's sensitivity is to have this flag set.
@GTK_PARENT_SENSITIVE: 
        Set and unset by gtk_widget_set_sensitive() operations on the
        parents of the widget.
        This is the second premise for the widget's sensitivity. Once
        it has %GTK_SENSITIVE and %GTK_PARENT_SENSITIVE set, its state is
        effectively sensitive. This is expressed (and can be examined) by
        the #GTK_WIDGET_IS_SENSITIVE macro.
@GTK_CAN_FOCUS: 
        Determines whether a widget is able to handle focus grabs.
@GTK_HAS_FOCUS: 
        Set by gtk_widget_grab_focus() for widgets that also
        have %GTK_CAN_FOCUS set. The flag will be unset once another widget
        grabs the focus.
@GTK_CAN_DEFAULT: 
        The widget is allowed to receive the default action via 
        gtk_widget_grab_default().
@GTK_HAS_DEFAULT: 
        The widget currently is receiving the default action.
@GTK_HAS_GRAB: 
        Set by gtk_grab_add(), unset by gtk_grab_remove(). It means that the 
        widget is in the grab_widgets stack, and will be the preferred one for 
        receiving events other than ones of cosmetic value.
@GTK_RC_STYLE: 
        Indicates that the widget's style has been looked up through the rc 
        mechanism. It does not imply that the widget actually had a style 
        defined through the rc mechanism.
@GTK_COMPOSITE_CHILD: 
        Indicates that the widget is a composite child of its parent; see 
        gtk_widget_push_composite_child(), gtk_widget_pop_composite_child().
@GTK_NO_REPARENT: 
        Unused since before GTK+ 1.2, will be removed in a future version.
@GTK_APP_PAINTABLE: 
        Set and unset by gtk_widget_set_app_paintable().
        Must be set on widgets whose window the application directly draws on, 
        in order to keep GTK+ from overwriting the drawn stuff.
@GTK_RECEIVES_DEFAULT: 
        The widget when focused will receive the default action and have 
        %GTK_HAS_DEFAULT set even if there is a different widget set as default.
@GTK_DOUBLE_BUFFERED: 
        Set and unset by gtk_widget_set_double_buffered().
        Indicates that exposes done on the widget should be double-buffered.
@GTK_NO_SHOW_ALL:
