class="link" href="GtkPaned.html" title="GtkPaned"><span class="type">GtkPaned</span></a> is the base class for widgets with two panes,arranged either horizontally (<a class="link" href="GtkHPaned.html" title="GtkHPaned"><span class="type">GtkHPaned</span></a>) orvertically (<a class="link" href="GtkVPaned.html" title="GtkVPaned"><span class="type">GtkVPaned</span></a>). Child widgets are added to the panes of the widget with<a class="link" href="GtkPaned.html#gtk-paned-pack1"><code class="function">gtk_paned_pack1()</code></a> and <a class="link" href="GtkPaned.html#gtk-paned-pack2"><code class="function">gtk_paned_pack2()</code></a>. The divisionbeween the two children is set by default from thesize requests of the children, but it can be adjustedby the user.</p><p>A paned widget draws a separator between the twochild widgets and a small handle that the usercan drag to adjust the division. It does notdraw any relief around the children or aroundthe separator. (The space in which the separatoris called the gutter.) Often, it is usefulto put each child inside a <a class="link" href="GtkFrame.html" title="GtkFrame"><span class="type">GtkFrame</span></a> with theshadow type set to <a class="link" href="gtk-Standard-Enumerations.html#GTK-SHADOW-IN:CAPS"><code class="literal">GTK_SHADOW_IN</code></a> so that thegutter appears as a ridge. No separator is drawnif one of the children is missing.</p><p>Each child has two options that can be set, <em class="parameter"><code>resize</code></em> and <em class="parameter"><code>shrink</code></em>. If <em class="parameter"><code>resize</code></em> is true, then when the<a class="link" href="GtkPaned.html" title="GtkPaned"><span class="type">GtkPaned</span></a> is resized, that child will expandor shrink along with the paned widget. If <em class="parameter"><code>shrink</code></em>is true, then when that child can be made smallerthan its requisition by the user. Setting <em class="parameter"><code>shrink</code></em>to <ahref="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#FALSE:CAPS"><code class="literal">FALSE</code></a> allows the application to set a minimumsize. If <em class="parameter"><code>resize</code></em> is false for both children, thenthis is treated as if <em class="parameter"><code>resize</code></em> is true for bothchildren.</p><p>The application can set the position of the slideras if it were set by the user, by calling<a class="link" href="GtkPaned.html#gtk-paned-set-position"><code class="function">gtk_paned_set_position()</code></a>.</p><div class="example"><a name="id4287971"></a><p class="title"><b>Example 46. Creating a paned widget with minimum sizes.</b></p><div class="example-contents"><pre class="programlisting">GtkWidget *hpaned = gtk_hpaned_new ();GtkWidget *frame1 = gtk_frame_new (NULL);GtkWidget *frame2 = gtk_frame_new (NULL);gtk_frame_set_shadow_type (GTK_FRAME (frame1), GTK_SHADOW_IN);gtk_frame_set_shadow_type (GTK_FRAME (frame2), GTK_SHADOW_IN);gtk_widget_set_size_request (hpaned, 200 + GTK_PANED (hpaned)->gutter_size, -1);gtk_paned_pack1 (GTK_PANED (hpaned), frame1, TRUE, FALSE);gtk_widget_set_size_request (frame1, 50, -1);gtk_paned_pack2 (GTK_PANED (hpaned), frame2, FALSE, FALSE);gtk_widget_set_size_request (frame2, 50, -1);</pre></div></div><br class="example-break"></div><div class="refsect1" lang="en"><a name="id4287997"></a><h2>Details</h2><div class="refsect2" lang="en"><a name="id4288007"></a><h3><a name="GtkPaned-struct"></a>GtkPaned</h3><a class="indexterm" name="id4288021"></a><pre class="programlisting">typedef struct _GtkPaned GtkPaned;</pre><p></p></div><hr><div class="refsect2" lang="en"><a name="id4288035"></a><h3><a name="gtk-paned-add1"></a>gtk_paned_add1 ()</h3><a class="indexterm" name="id4288048"></a><pre class="programlisting">void gtk_paned_add1 (<a class="link" href="GtkPaned.html" title="GtkPaned">GtkPaned</a> *paned, <a class="link" href="GtkWidget.html" title="GtkWidget">GtkWidget</a> *child);</pre><p>Adds a child to the top or left pane withdefault parameters.
