Re: Basic GNOME applet developement

[James Scott Jr <skoona verizon net>]

Andrew,

Where are you with this problem now?  I have tried to review your posts
to better understand your dilemma, and I can make one suggestion in
reference to "add to gnome bar and it doesn't show anything".

When you have the *.server file correct, and your C code correct, in
that your printf's show console output.  Your issue may simply be that
you never added your widgets to the applet itself.  In GTK there is
always a top level window/widget which everything gets added to.  In a
gnome applet the applet itself is that top-level window.  This snippet
will attach your event_box widget to the applet, so it can be shown.

static gboolean
myexample_applet_fill (PanelApplet *applet,
   const gchar *iid,
   gpointer data)

{
...
gtk_container_add (GTK_CONTAINER(event_box),image);
gtk_container_add (GTK_CONTAINER (applet), event_box);
...
gtk_widget_show_all (GTK_WIDGET (applet));
...
}

James,
I think I sent you this link before; but here it is again - a skeleton
gnome applet program.
