I am a novice at using GTK with Glade. I was wondering if anyone knew of an=
=
example or how to use/manipulate a table.
I need a way where the user can enter n number of information onto the =
table. Is there a table widget I missed=3F I thought there was one.=20

Hi Janmejay,
you can use the following way to set a callback for click
<pre>
GtkWidget *eventbox;
GtkWidget *label;
g_signal_connect ((gpointer) label, "button_press_event",
G_CALLBACK (on_label_button_press_event),
NULL);
//be sure to use this if you use only a label, or you can just add a
//label to eventbox, eventbox also has this button_press_event
gtk_label_set_selectable (GTK_LABEL (label), TRUE);
//the callback function
gboolean
on_label_button_press_event (GtkWidget *widget,
GdkEventButton *event,
gpointer user_data)
{
//TODO: add you own code here.
/* you can think that click_event is a button_press_event follow by
a button_release_event, here you can change a flag that indicates
the button has been pressed, then process the button_release_event
to complete a click event callback.
*/
return FALSE;
}
</pre>
=66or a full event types of GDK, you can refer to the
appendix B in gtk tutorial=20
(http://www.gtk.org/tutorial/app-gdkeventtypes.html)
I've also attached an example code,
Regards,
Sam Jiang
