I found a solution, but I am not sure it is a good way to do that.
I use ctree but clist is the same.
I connect the event signal to the ctree
gtk_signal_connect (GTK_OBJECT (ctree), "event", GTK_SIGNAL_FUNC
(ctree_event), NULL);
then in my callback I send the signal drag with this
static gint where_press;
if (GASPARD_VERY_CHAT) g_print ("Enter in ctree_event\n");
switch (ev->type) {
case GDK_BUTTON_PRESS : {
switch (ev->button.button) {
case 1 : {
drag_icon = gdk_pixmap_colormap_create_from_xpm_d (NULL,
gtk_widget_get_colormap (mainApp_Window),
&drag_mask, NULL, GASPARD_DRAG_ICON);
gtk_drag_source_set (ctree, GDK_BUTTON1_MASK, target_slot, 1,
GDK_ACTION_COPY|GDK_ACTION_MOVE);
gtk_drag_source_set_icon (ctree,
gtk_widget_get_colormap
(mainApp_Window),
drag_icon, drag_mask);
gdk_pixmap_unref (drag_icon);
gdk_pixmap_unref (drag_mask);
gtk_signal_connect (GTK_OBJECT (ctree), "drag_data_get",
GTK_SIGNAL_FUNC (source_drag_data_get));
gtk_signal_connect (GTK_OBJECT (ctree), "drag_data_delete",
GTK_SIGNAL_FUNC (source_drag_data_delete),
key);
}
}
}
}And that is all I have to do. The advantage of this method is that you
can have a
different icon, for every different line in the clist
Hope this help
