<p><a name="style-properties"></a>
<span class="structname">GtkWidget</span> introduces <em class="firstterm">style
properties</em> - 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 <a href="gtk-Resource-Files.html" title="Resource Files">resource files</a>.
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.
</p>
<p>
Use <a href="GtkWidget.html#gtk-widget-class-install-style-property"><code class="function">gtk_widget_class_install_style_property()</code></a> to install style properties for
a widget class, <a href="GtkWidget.html#gtk-widget-class-find-style-property"><code class="function">gtk_widget_class_find_style_property()</code></a> or
<a href="GtkWidget.html#gtk-widget-class-list-style-properties"><code class="function">gtk_widget_class_list_style_properties()</code></a> to get information about existing

Destroys a widget. Equivalent to <a href="GtkObject.html#gtk-object-destroy"><code class="function">gtk_object_destroy()</code></a>, except that
you don't have to cast the widget to <a href="GtkObject.html" title="GtkObject"><span class="type">GtkObject</span></a>. When a widget is
destroyed, it will break any references it holds to other objects.
If the widget is inside a container, the widget will be removed
from the container. If the widget is a toplevel (derived from
<a href="GtkWindow.html" title="GtkWindow"><span class="type">GtkWindow</span></a>), it will be removed from the list of toplevels, and the
reference GTK+ holds to it will be removed. Removing a
widget from its container or the list of toplevels results in the
widget being finalized, unless you've added additional references
to the widget with <a

<p>
Creates the GDK (windowing system) resources associated with a
widget. For example, <em class="parameter"><code>widget->window</code></em> will be created when a widget
is realized. Normally realization happens implicitly; if you show
a widget and all its parent containers, then the widget will be
realized and mapped automatically.
</p>
<p>
Realizing a widget requires all
the widget's parent widgets to be realized; calling
<a href="GtkWidget.html#gtk-widget-realize"><code class="function">gtk_widget_realize()</code></a> realizes the widget's parents in addition to
<em class="parameter"><code>widget</code></em> itself. If a widget is not yet inside a toplevel window
when you realize it, bad things will happen.
</p>
<p>
This function is primarily used in widget implementations, and
isn't very useful otherwise. Many times when you think you might
need it, a better approach is to connect to a signal that will be
called after the widget is realized automatically, such as
"expose_event". Or simply <a

In GTK+ 1.2, this function would immediately render the
region <em class="parameter"><code>area</code></em> of a widget, by invoking the virtual draw method of a
widget. In GTK+ 2.0, the draw method is gone, and instead
<a href="GtkWidget.html#gtk-widget-draw"><code class="function">gtk_widget_draw()</code></a> simply invalidates the specified region of the

Usually you don't want to update the region immediately for
performance reasons, so in general <a href="GtkWidget.html#gtk-widget-queue-draw-area"><code class="function">gtk_widget_queue_draw_area()</code></a> is

This function is typically used when implementing a <a href="GtkContainer.html" title="GtkContainer"><span class="type">GtkContainer</span></a>

</p>
<p>
You can also call this function from an application, with some
caveats. Most notably, getting a size request requires the widget
to be associated with a screen, because font information may be
needed. Multihead-aware applications should keep this in mind.

<p>
Also remember that the size request is not necessarily the size
a widget will actually be allocated.

geometry on the widget (e.g. with <a href="GtkWidget.html#gtk-widget-set-usize"><code class="function">gtk_widget_set_usize()</code></a>), in which
case it returns that geometry instead of the widget's requisition.
</p>
<p>
This function differs from <a href="GtkWidget.html#gtk-widget-size-request"><code class="function">gtk_widget_size_request()</code></a> in that
it retrieves the last size request value from <em class="parameter"><code>widget->requisition</code></em>,
while <a href="GtkWidget.html#gtk-widget-size-request"><code class="function">gtk_widget_size_request()</code></a> actually calls the "size_request" method
on <em class="parameter"><code>widget</code></em> to compute the size request and fill in <em class="parameter"><code>widget->requisition</code></em>,
and only then returns <em class="parameter"><code>widget->requisition</code></em>.
</p>
<p>
Because this function does not call the "size_request" method, it
can only be used when you know that <em class="parameter"><code>widget->requisition</code></em> is
up-to-date, that is, <a href="GtkWidget.html#gtk-widget-size-request"><code class="function">gtk_widget_size_request()</code></a> has been called
since the last time a resize was queued. In general, only container
implementations have this information; applications should use
<a href="GtkWidget.html#gtk-widget-size-request"><code class="function">gtk_widget_size_request()</code></a>.</p>

Sets the position of a widget. The funny "u" in the name comes from
the "user position" hint specified by the X Window System, and
exists for legacy reasons. This function doesn't work if a widget
is inside a container; it's only really useful on <a href="GtkWindow.html" title="GtkWindow"><span class="type">GtkWindow</span></a>.
</p>
<p>
Don't use this function to center dialogs over the main application
window; most window managers will do the centering on your behalf
if you call <a href="GtkWindow.html#gtk-window-set-transient-for"><code class="function">gtk_window_set_transient_for()</code></a>, and it's really not
possible to get the centering to work correctly in all cases from
application code. But if you insist, use <a href="GtkWindow.html#gtk-window-set-position"><code class="function">gtk_window_set_position()</code></a>
to set <a href="gtk-Standard-Enumerations.html#GTK-WIN-POS-CENTER-ON-PARENT:CAPS"><span class="type">GTK_WIN_POS_CENTER_ON_PARENT</span></a>, don't do the centering
manually.
</p>
<p>
Note that although <em class="parameter"><code>x</code></em> and <em class="parameter"><code>y</code></em> can be individually unset, the position
is not honoured unless both <em class="parameter"><code>x</code></em> and <em class="parameter"><code>y</code></em> are set.</p>

Sets the minimum size of a widget; that is, the widget's size
request will be <em class="parameter"><code>width</code></em> by <em class="parameter"><code>height</code></em>. You can use this function to
force a widget to be either larger or smaller than it is. The
strange "usize" name dates from the early days of GTK+, and derives
from X Window System terminology. In many cases,
<a href="GtkWindow.html#gtk-window-set-default-size"><code class="function">gtk_window_set_default_size()</code></a> is a better choice for toplevel
windows than this function; setting the default size will still
allow users to shrink the window. Setting the usize will force them
to leave the window at least as large as the usize. When dealing
with window sizes, <a href="GtkWindow.html#gtk-window-set-geometry-hints"><code class="function">gtk_window_set_geometry_hints()</code></a> can be a useful
function as well.
</p>
<p>
Note the inherent danger of setting any fixed size - themes,
translations into other languages, different fonts, and user action
can all change the appropriate size for a given widget. So, it's
basically impossible to hardcode a size that will always be
correct.

<p>
Modifies style values on the widget. Modifications made using this
technique take precedence over style values set via an RC file,
however, they will be overriden if a style is explicitely set on
the widget using <a href="GtkWidget.html#gtk-widget-set-style"><code class="function">gtk_widget_set_style()</code></a>. The <a href="gtk-Resource-Files.html#GtkRcStyle"><span class="type">GtkRcStyle</span></a> structure
is designed so each field can either be set or unset, so it is
possible, using this function, to modify some style values and
leave the others unchanged.
</p>
<p>
Note that modifications made with this function are not cumulative
with previous calls to <a href="GtkWidget.html#gtk-widget-modify-style"><code class="function">gtk_widget_modify_style()</code></a> or with such
functions as <a href="GtkWidget.html#gtk-widget-modify-fg"><code class="function">gtk_widget_modify_fg()</code></a>. If you wish to retain
previous values, you must first call <a href="GtkWidget.html#gtk-widget-get-modifier-style"><code class="function">gtk_widget_get_modifier_style()</code></a>,
make your modifications to the returned style, then call
<a href="GtkWidget.html#gtk-widget-modify-style"><code class="function">gtk_widget_modify_style()</code></a> with that style. On the other hand,
if you first call <a href="GtkWidget.html#gtk-widget-modify-style"><code class="function">gtk_widget_modify_style()</code></a>, subsequent calls
to such functions <a href="GtkWidget.html#gtk-widget-modify-fg"><code class="function">gtk_widget_modify_fg()</code></a> will have a cumulative

Returns the current modifier style for the widget. (As set by
<a href="GtkWidget.html#gtk-widget-modify-style"><code class="function">gtk_widget_modify_style()</code></a>.) If no style has previously set, a new
<a href="gtk-Resource-Files.html#GtkRcStyle"><span class="type">GtkRcStyle</span></a> will be created with all values unset, and set as the
modifier style for the widget. If you make changes to this rc
style, you must call <a href="GtkWidget.html#gtk-widget-modify-style"><code class="function">gtk_widget_modify_style()</code></a>, passing in the
returned rc style, to make sure that your changes take effect.
</p>
<p>
Caution: passing the style back to <a href="GtkWidget.html#gtk-widget-modify-style"><code class="function">gtk_widget_modify_style()</code></a> will
normally end up destroying it, because <a href="GtkWidget.html#gtk-widget-modify-style"><code class="function">gtk_widget_modify_style()</code></a> copies
the passed-in style and sets the copy as the new modifier style,
thus dropping any reference to the old modifier style. Add a reference

Invalidates the rectangular area of <em class="parameter"><code>widget</code></em> defined by <em class="parameter"><code>x</code></em>, <em class="parameter"><code>y</code></em>,
<em class="parameter"><code>width</code></em> and <em class="parameter"><code>height</code></em> by calling <a
href="../gdk/gdk-Windows.html#gdk-window-invalidate-rect"
><code class="function">gdk_window_invalidate_rect()</code></a> on the
widget's window and all its child windows. Once the main loop
becomes idle (after the current batch of events has been processed,
roughly), the window will receive expose events for the union of
all regions that have been invalidated.
</p>
<p>
Normally you would only use this function in widget
implementations. You might also use it, or
<a
href="../gdk/gdk-Windows.html#gdk-window-invalidate-rect"
><code class="function">gdk_window_invalidate_rect()</code></a> directly, to schedule a redraw of a
<a href="GtkDrawingArea.html" title="GtkDrawingArea"><span class="type">GtkDrawingArea</span></a> or some portion thereof.
</p>
<p>
Frequently you can just call <a
href="../gdk/gdk-Windows.html#gdk-window-invalidate-rect"
><code class="function">gdk_window_invalidate_rect()</code></a> or
<a
href="../gdk/gdk-Windows.html#gdk-window-invalidate-region"
><code class="function">gdk_window_invalidate_region()</code></a> instead of this function. Those
functions will invalidate only a single window, instead of the
widget and all its children.
</p>
<p>
The advantage of adding to the invalidated region compared to
simply drawing immediately is efficiency; using an invalid region
ensures that you only have to redraw one time.</p>

This is a hint to the widget and does not affect the behavior of

the effect is to suppress default themed drawing of the widget's

</p>

Note that the background is still drawn when the widget is mapped.

<a
href="../glib/glib-Basic-Types.html#gboolean"
>gboolean</a> double_buffered);</pre>
<p>
Widgets are double buffered by default; you can use this function
to turn off the buffering. "Double buffered" simply means that
<a
href="../gdk/gdk-Windows.html#gdk-window-begin-paint-region"
><code class="function">gdk_window_begin_paint_region()</code></a> and <a
href="../gdk/gdk-Windows.html#gdk-window-end-paint"
><code class="function">gdk_window_end_paint()</code></a> are called
automatically around expose events sent to the
widget. <code class="function">gdk_window_begin_paint()</code> diverts all drawing to a widget's
window to an offscreen buffer, and <a
href="../gdk/gdk-Windows.html#gdk-window-end-paint"
><code class="function">gdk_window_end_paint()</code></a> draws the
buffer to the screen. The result is that users see the window
update in one smooth step, and don't see individual graphics
primitives being rendered.
</p>
<p>
In very simple terms, double buffered widgets don't flicker,
so you would only use this function to turn off double buffering
if you had special needs and really knew what you were doing.
</p>
<p>
Note: if you turn off double-buffering, you have to handle
expose events, since even the clearing to the background color or
pixmap will not happen automatically (as it is done in
<code class="function">gdk_window_begin_paint()</code>).</p>

"focus" signal on <a href="GtkWidget.html" title="GtkWidget"><span class="type">GtkWidget</span></a>; widgets override the default handler
for this signal in order to implement appropriate focus behavior.
</p>
<p>
The "focus" default handler for a widget should return <a
href="../glib/glib-Standard-Macros.html#TRUE:CAPS"
><code class="literal">TRUE</code></a> if
moving in <em class="parameter"><code>direction</code></em> left the focus on a focusable location inside
that widget, and <a
href="../glib/glib-Standard-Macros.html#FALSE:CAPS"
><code class="literal">FALSE</code></a> if moving in <em class="parameter"><code>direction</code></em> moved the focus
outside the widget. If returning <a
href="../glib/glib-Standard-Macros.html#TRUE:CAPS"
><code class="literal">TRUE</code></a>, widgets normally
call <a href="GtkWidget.html#gtk-widget-grab-focus"><code class="function">gtk_widget_grab_focus()</code></a> to place the focus accordingly;
if returning <a
href="../glib/glib-Standard-Macros.html#FALSE:CAPS"
><code class="literal">FALSE</code></a>, they don't modify the current focus location.
</p>
<p>
This function replaces <code class="function">gtk_container_focus()</code> from GTK+ 1.2. It was
necessary to check that the child was visible, sensitive, and
focusable before calling
<code class="function">gtk_container_focus()</code>. <a href="GtkWidget.html#gtk-widget-child-focus"><code class="function">gtk_widget_child_focus()</code></a> returns <a
href="../glib/glib-Standard-Macros.html#FALSE:CAPS"
><code class="literal">FALSE</code></a> if
the widget is not currently in a focusable state, so there's no
need for those checks.</p>

<a href="GtkWindow.html#gtk-window-set-geometry-hints"><code class="function">gtk_window_set_geometry_hints()</code></a> can be a useful function as well.
</p>
<p>
Note the inherent danger of setting any fixed size - themes,
translations into other languages, different fonts, and user action
can all change the appropriate size for a given widget. So, it's
basically impossible to hardcode a size that will always be
correct.
</p>
<p>
The size request of a widget is the smallest size a widget can
accept while still functioning well and drawing itself correctly.
However in some strange cases a widget may be allocated less than
its requested size, and in many cases a widget may be allocated more
space than it requested.
</p>
<p>
If the size request in a given direction is -1 (unset), then
the "natural" size request of the widget will be used instead.
</p>
<p>
Widgets can't actually be allocated a size less than 1 by 1, but
you can pass 0,0 to this function to mean "as small as possible."</p>

The ::drag-motion signal is emitted on the drop site when the user
moves the cursor over the widget during a drag. The signal handler
must determine whether the cursor position is in a drop zone or not.
If it is not in a drop zone, it returns <a
href="../glib/glib-Standard-Macros.html#FALSE:CAPS"
><code class="literal">FALSE</code></a> and no further processing
is necessary. Otherwise, the handler returns <a
href="../glib/glib-Standard-Macros.html#TRUE:CAPS"
><code class="literal">TRUE</code></a>. In this case, the
handler is responsible for providing the necessary information for
displaying feedback to the user, by calling <a
href="../gdk/gdk-Drag-and-Drop.html#gdk-drag-status"
><code class="function">gdk_drag_status()</code></a>. If the
decision whether the drop will be accepted or rejected can't be made
based solely on the cursor position and the type of the data, the handler
may inspect the dragged data by calling <a href="gtk-Drag-and-Drop.html#gtk-drag-get-data"><code class="function">gtk_drag_get_data()</code></a> and defer the
<a
href="../gdk/gdk-Drag-and-Drop.html#gdk-drag-status"
><code class="function">gdk_drag_status()</code></a> call to the ::drag-data-received handler.
</p>
<p>
Note that there is no ::drag-enter signal. The drag receiver has to keep
track of whether he has received any ::drag-motion signals since the last
::drag-leave and if not, treat the ::drag-motion signal as an "enter" signal.
Upon an "enter", the handler will typically highlight the drop site with
<a href="gtk-Drag-and-Drop.html#gtk-drag-highlight"><code class="function">gtk_drag_highlight()</code></a>.

<p>
This signal gets emitted whenever a widget should pop up a context-sensitive
menu. This usually happens through the standard key binding mechanism; by
pressing a certain key while a widget is focused, the user can cause the
widget to pop up a menu. For example, the <a href="GtkEntry.html" title="GtkEntry"><span class="type">GtkEntry</span></a> widget creates a menu
with clipboard commands. See <a href="gtk-migrating-checklist.html#checklist-popup-menu" title="Implement GtkWidget::popup_menu">the section called “Implement GtkWidget::popup_menu”</a> for an
example of how to use this signal.</p>
