Each routine has a <span class="STRUCTNAME"> _parented()</span> variant which calls <tt class= "FUNCTION">gnome_dialog_set_parent()</tt>. The three function pairs in <a href= "sec-dialogs-convenience.html#FL-CONVENIENCEDIALOGS">Figure 11</a> display an info box, a warning box, and an error box, respectively; they create and show the widget, so you can ignore the return value if you like. </p> <p> The only purpose of these functions is to save you typing. They are pure syntactic sugar. I find it much easier to remember them than to use <tt class="FUNCTION"> gnome_message_box_new()</tt>, though; I always forget the order of the arguments to <tt class="FUNCTION"> gnome_message_box_new()</tt>. </p> <div class="FIGURE"> <a name="FL-CONVENIENCEDIALOGS"></a> <div class="FUNCSYNOPSIS"> <a name="FL-CONVENIENCEDIALOGS.SYNOPSIS"></a> <table border="0" bgcolor="#E0E0E0" width="100%"> <tr> <td><pre class="FUNCSYNOPSISINFO"> #include <libgnomeui/gnome-dialog-util.h> </pre> </td> </tr> </table> <p> <code><code class="FUNCDEF">GtkWidget* <tt class= "FUNCTION">gnome_ok_dialog</tt></code>(const gchar* <tt class="PARAMETER"><i>message</i></tt>);</code> </p> <p> <code><code class="FUNCDEF">GtkWidget* <tt class= "FUNCTION">gnome_ok_dialog_parented</tt></code>(const gchar* <tt class="PARAMETER"><i>message</i></tt>, GtkWindow* <tt class="PARAMETER"><i> parent</i></tt>);</code> </p> <p> <code><code class="FUNCDEF">GtkWidget* <tt class= "FUNCTION">gnome_warning_dialog</tt></code>(const gchar* <tt class="PARAMETER"><i> warning</i></tt>);</code> </p> <p> <code><code class="FUNCDEF">GtkWidget* <tt class= "FUNCTION"> gnome_warning_dialog_parented</tt></code>(const gchar* <tt class="PARAMETER"><i>warning</i></tt>, GtkWindow* <tt class="PARAMETER"><i>parent</i></tt>);</code> </p> <p> <code><code class="FUNCDEF">GtkWidget* <tt class= "FUNCTION">gnome_error_dialog</tt></code>(const gchar* <tt class="PARAMETER"><i>error</i></tt>);</code> </p> <p> <code><code class="FUNCDEF">GtkWidget* <tt class= "FUNCTION"> gnome_error_dialog_parented</tt></code>(const gchar* <tt class="PARAMETER"><i>error</i></tt>, GtkWindow* <tt class="PARAMETER"><i>parent</i></tt>);</code> </p> </div> <p> <b>Figure 11.
