A <tt class= "CLASSNAME">GnomeApp</tt> window is automatically user-configurable in several ways: </p> <ul> <li> <p> Menu and toolbars can be detached from the window, or rearranged in relation to one another and the main window contents. </p> </li> <li> <p> Users can elect to disable detachable bars for all Gnome applications. </p> </li> <li> <p> Users can choose whether to have small icons in the application's menus. </p> </li> </ul> <p> More options will probably be added in the future. </p> <div class="FIGURE"> <a name="Z88"></a> <p> <img src="figures/gnumeric.png"> </p> <p> <b>Figure 1.

It should be the same as the <span class= "STRUCTNAME">app_id</span> passed to <tt class= "FUNCTION">gnome_init()</tt>; the name of the executable is a good choice. The second argument is simply a title for the application window; if you use <tt class= "FUNCTION">NULL</tt> here, the title will not be set. </p> <div class="FIGURE"> <a name="FL-GNOMEAPPNEW"></a> <div class="FUNCSYNOPSIS"> <a name="FL-GNOMEAPPNEW.SYNOPSIS"></a> <table border="0" bgcolor="#E0E0E0" width="100%"> <tr> <td><pre class="FUNCSYNOPSISINFO">#include <libgnomeui/gnome-app.h></pre> </td> </tr> </table> <p> <code><code class="FUNCDEF">GtkWidget* <tt class= "FUNCTION">gnome_app_new</tt></code>(gchar* <tt class="PARAMETER"><i>app_id</i></tt>, gchar* <tt class="PARAMETER"><i>title</i></tt>);</code> </p> </div> <p> <b>Figure 2. <tt class="CLASSNAME">GnomeApp</tt> Constructor</b> </p> </div> <p> <tt class="CLASSNAME">GnomeApp</tt> has a single "content area" in the center, where you place the main functionality of your application.
