<a name="GtkCellArea.description"></a><h2>Description</h2>
<p>The <a class="link" href="GtkCellArea.html" title="GtkCellArea"><span class="type">GtkCellArea</span></a> is an abstract class for <a class="link" href="GtkCellLayout.html" title="GtkCellLayout"><span class="type">GtkCellLayout</span></a> widgets
(also referred to as "layouting widgets") to interface with an
arbitrary number of <a href="GtkCellRenderer.html#GtkCellRenderer-struct"><span class="type">GtkCellRenderers</span></a> and interact with the user
for a given <a class="link" href="GtkTreeModel.html" title="GtkTreeModel"><span class="type">GtkTreeModel</span></a> row.</p>
<p>The cell area handles events, focus navigation, drawing and
size requests and allocations for a given row of data.</p>
<p>Usually users dont have to interact with the <a class="link" href="GtkCellArea.html" title="GtkCellArea"><span class="type">GtkCellArea</span></a> directly
unless they are implementing a cell-layouting widget themselves.</p>
<div class="refsect2">
<a name="id-1.3.12.14.10.5"></a><h3>Requesting area sizes</h3>
<p>As outlined in
<a class="link" href="GtkWidget.html#geometry-management" title="Height-for-width Geometry Management">GtkWidgets geometry management section</a>,
GTK+ uses a height-for-width
geometry management system to compute the sizes of widgets and user
interfaces. <a class="link" href="GtkCellArea.html" title="GtkCellArea"><span class="type">GtkCellArea</span></a> uses the same semantics to calculate the
size of an area for an arbitrary number of <a class="link" href="GtkTreeModel.html" title="GtkTreeModel"><span class="type">GtkTreeModel</span></a> rows.</p>
<p>When requesting the size of a cell area one needs to calculate
the size for a handful of rows, and this will be done differently by
different layouting widgets. For instance a <a class="link" href="GtkTreeViewColumn.html" title="GtkTreeViewColumn"><span class="type">GtkTreeViewColumn</span></a>
always lines up the areas from top to bottom while a <a class="link" href="GtkIconView.html" title="GtkIconView"><span class="type">GtkIconView</span></a>
on the other hand might enforce that all areas received the same
width and wrap the areas around, requesting height for more cell
areas when allocated less width.</p>
<p>Its also important for areas to maintain some cell
alignments with areas rendered for adjacent rows (cells can
appear “columnized” inside an area even when the size of
cells are different in each row). For this reason the <a class="link" href="GtkCellArea.html" title="GtkCellArea"><span class="type">GtkCellArea</span></a>
uses a <a class="link" href="GtkCellAreaContext.html" title="GtkCellAreaContext"><span class="type">GtkCellAreaContext</span></a> object to store the alignments
and sizes along the way (as well as the overall largest minimum
and natural size for all the rows which have been calculated
with the said context).</p>
<p>The <a class="link" href="GtkCellAreaContext.html" title="GtkCellAreaContext"><span class="type">GtkCellAreaContext</span></a> is an opaque object specific to the
<a class="link" href="GtkCellArea.html" title="GtkCellArea"><span class="type">GtkCellArea</span></a> which created it (see <a class="link" href="GtkCellArea.html#gtk-cell-area-create-context" title="gtk_cell_area_create_context ()"><code class="function">gtk_cell_area_create_context()</code></a>).
The owning cell-layouting widget can create as many contexts as
it wishes to calculate sizes of rows which should receive the
same size in at least one orientation (horizontally or vertically),
However, its important that the same <a class="link" href="GtkCellAreaContext.html" title="GtkCellAreaContext"><span class="type">GtkCellAreaContext</span></a> which
was used to request the sizes for a given <a class="link" href="GtkTreeModel.html" title="GtkTreeModel"><span class="type">GtkTreeModel</span></a> row be
used when rendering or processing events for that row.</p>
<p>In order to request the width of all the rows at the root level
of a <a class="link" href="GtkTreeModel.html" title="GtkTreeModel"><span class="type">GtkTreeModel</span></a> one would do the following:</p>

<p>Note that in this example its not important to observe the
returned minimum and natural width of the area for each row
unless the cell-layouting object is actually interested in the
widths of individual rows. The overall width is however stored
in the accompanying <a class="link" href="GtkCellAreaContext.html" title="GtkCellAreaContext"><span class="type">GtkCellAreaContext</span></a> object and can be consulted
at any time.</p>
<p>This can be useful since <a class="link" href="GtkCellLayout.html" title="GtkCellLayout"><span class="type">GtkCellLayout</span></a> widgets usually have to
support requesting and rendering rows in treemodels with an
exceedingly large amount of rows. The <a class="link" href="GtkCellLayout.html" title="GtkCellLayout"><span class="type">GtkCellLayout</span></a> widget in
that case would calculate the required width of the rows in an
idle or timeout source (see <code class="function">g_timeout_add()</code>) and when the widget
is requested its actual width in <a class="link" href="GtkWidget.html#GtkWidgetClass.get-preferred-width"><code class="function">GtkWidgetClass.get_preferred_width()</code></a>
it can simply consult the width accumulated so far in the
<a class="link" href="GtkCellAreaContext.html" title="GtkCellAreaContext"><span class="type">GtkCellAreaContext</span></a> object.</p>
<p>A simple example where rows are rendered from top to bottom and
take up the full width of the layouting widget would look like:</p>

<p>In the above example the Foo widget has to make sure that some
row sizes have been calculated (the amount of rows that Foo judged
was appropriate to request space for in a single timeout iteration)
before simply returning the amount of space required by the area via
the <a class="link" href="GtkCellAreaContext.html" title="GtkCellAreaContext"><span class="type">GtkCellAreaContext</span></a>.</p>
<p>Requesting the height for width (or width for height) of an area is
a similar task except in this case the <a class="link" href="GtkCellAreaContext.html" title="GtkCellAreaContext"><span class="type">GtkCellAreaContext</span></a> does not
store the data (actually, it does not know how much space the layouting
widget plans to allocate it for every row. Its up to the layouting
widget to render each row of data with the appropriate height and
width which was requested by the <a class="link" href="GtkCellArea.html" title="GtkCellArea"><span class="type">GtkCellArea</span></a>).</p>
<p>In order to request the height for width of all the rows at the

<p>Note that in the above example we would need to cache the heights
returned for each row so that we would know what sizes to render the
areas for each row. However we would only want to really cache the
heights if the request is intended for the layouting widgets real
allocation.</p>
<p>In some cases the layouting widget is requested the height for an
arbitrary for_width, this is a special case for layouting widgets
who need to request size for tens of thousands of rows. For this
case its only important that the layouting widget calculate
one reasonably sized chunk of rows and return that height
synchronously. The reasoning here is that any layouting widget is
at least capable of synchronously calculating enough height to fill
the screen height (or scrolled window height) in response to a single
call to <a class="link" href="GtkWidget.html#GtkWidgetClass.get-preferred-height-for-width"><code class="function">GtkWidgetClass.get_preferred_height_for_width()</code></a>. Returning
a perfect height for width that is larger than the screen area is
inconsequential since after the layouting receives an allocation
from a scrolled window it simply continues to drive the scrollbar
values while more and more height is required for the row heights
that are calculated in the background.</p>

<p>Note that the cached height in this example really depends on how
the layouting widget works. The layouting widget might decide to
give every row its minimum or natural height or, if the model content
is expected to fit inside the layouting widget without scrolling, it
would make sense to calculate the allocation for each row at
<a class="link" href="GtkWidget.html#GtkWidget-size-allocate" title="The “size-allocate” signal"><span class="type">“size-allocate”</span></a> time using <a class="link" href="GtkWidget.html#gtk-distribute-natural-allocation" title="gtk_distribute_natural_allocation ()"><code class="function">gtk_distribute_natural_allocation()</code></a>.</p>

<a name="id-1.3.12.14.10.7"></a><h3>Handling Events and Driving Keyboard Focus</h3>
<p>Passing events to the area is as simple as handling events on any
normal widget and then passing them to the <a class="link" href="GtkCellArea.html#gtk-cell-area-event" title="gtk_cell_area_event ()"><code class="function">gtk_cell_area_event()</code></a>
API as they come in. Usually <a class="link" href="GtkCellArea.html" title="GtkCellArea"><span class="type">GtkCellArea</span></a> is only interested in
button events, however some customized derived areas can be implemented
who are interested in handling other events. Handling an event can
trigger the <a class="link" href="GtkCellArea.html#GtkCellArea-focus-changed" title="The “focus-changed” signal"><span class="type">“focus-changed”</span></a> signal to fire; as well as
<a class="link" href="GtkCellArea.html#GtkCellArea-add-editable" title="The “add-editable” signal"><span class="type">“add-editable”</span></a> in the case that an editable cell was
clicked and needs to start editing. You can call
<a class="link" href="GtkCellArea.html#gtk-cell-area-stop-editing" title="gtk_cell_area_stop_editing ()"><code class="function">gtk_cell_area_stop_editing()</code></a> at any time to cancel any cell editing
that is currently in progress.</p>
<p>The <a class="link" href="GtkCellArea.html" title="GtkCellArea"><span class="type">GtkCellArea</span></a> drives keyboard focus from cell to cell in a way
similar to <a class="link" href="GtkWidget.html" title="GtkWidget"><span class="type">GtkWidget</span></a>. For layouting widgets that support giving
focus to cells its important to remember to pass <a class="link" href="GtkCellRenderer.html#GTK-CELL-RENDERER-FOCUSED:CAPS"><code class="literal">GTK_CELL_RENDERER_FOCUSED</code></a>
to the area functions for the row that has focus and to tell the
area to paint the focus at render time.</p>
<p>Layouting widgets that accept focus on cells should implement the
<a class="link" href="GtkWidget.html#GtkWidgetClass.focus"><code class="function">GtkWidgetClass.focus()</code></a> virtual method. The layouting widget is always
responsible for knowing where <a class="link" href="GtkTreeModel.html" title="GtkTreeModel"><span class="type">GtkTreeModel</span></a> rows are rendered inside
the widget, so at <a class="link" href="GtkWidget.html#GtkWidgetClass.focus"><code class="function">GtkWidgetClass.focus()</code></a> time the layouting widget
should use the <a class="link" href="GtkCellArea.html" title="GtkCellArea"><span class="type">GtkCellArea</span></a> methods to navigate focus inside the area
and then observe the GtkDirectionType to pass the focus to adjacent
rows and areas.</p>
<p>A basic example of how the <a class="link" href="GtkWidget.html#GtkWidgetClass.focus"><code class="function">GtkWidgetClass.focus()</code></a> virtual method
should be implemented:</p>

<a name="id-1.3.12.14.10.8"></a><h3>Cell Properties</h3>
<p>The <a class="link" href="GtkCellArea.html" title="GtkCellArea"><span class="type">GtkCellArea</span></a> introduces cell properties for <a href="GtkCellRenderer.html#GtkCellRenderer-struct"><span class="type">GtkCellRenderers</span></a>
in very much the same way that <a class="link" href="GtkContainer.html" title="GtkContainer"><span class="type">GtkContainer</span></a> introduces
child properties
for <a href="GtkWidget.html#GtkWidget-struct"><span class="type">GtkWidgets</span></a>. This provides some general interfaces for defining
the relationship cell areas have with their cells. For instance in a
<a class="link" href="GtkCellAreaBox.html" title="GtkCellAreaBox"><span class="type">GtkCellAreaBox</span></a> a cell might “expand” and receive extra space when
the area is allocated more than its full natural request, or a cell
might be configured to “align” with adjacent rows which were requested
and rendered with the same <a class="link" href="GtkCellAreaContext.html" title="GtkCellAreaContext"><span class="type">GtkCellAreaContext</span></a>.</p>
<p>Use <a class="link" href="GtkCellArea.html#gtk-cell-area-class-install-cell-property" title="gtk_cell_area_class_install_cell_property ()"><code class="function">gtk_cell_area_class_install_cell_property()</code></a> to install cell
properties for a cell area class and <a class="link" href="GtkCellArea.html#gtk-cell-area-class-find-cell-property" title="gtk_cell_area_class_find_cell_property ()"><code class="function">gtk_cell_area_class_find_cell_property()</code></a>
or <a class="link" href="GtkCellArea.html#gtk-cell-area-class-list-cell-properties" title="gtk_cell_area_class_list_cell_properties ()"><code class="function">gtk_cell_area_class_list_cell_properties()</code></a> to get information about
existing cell properties.</p>
<p>To set the value of a cell property, use <a class="link" href="GtkCellArea.html#gtk-cell-area-cell-set-property" title="gtk_cell_area_cell_set_property ()"><code class="function">gtk_cell_area_cell_set_property()</code></a>,
<a class="link" href="GtkCellArea.html#gtk-cell-area-cell-set" title="gtk_cell_area_cell_set ()"><code class="function">gtk_cell_area_cell_set()</code></a> or <a class="link" href="GtkCellArea.html#gtk-cell-area-cell-set-valist" title="gtk_cell_area_cell_set_valist ()"><code class="function">gtk_cell_area_cell_set_valist()</code></a>. To obtain
the value of a cell property, use <a class="link" href="GtkCellArea.html#gtk-cell-area-cell-get-property" title="gtk_cell_area_cell_get_property ()"><code class="function">gtk_cell_area_cell_get_property()</code></a>,
