RE: Tooltips (or similar) on a drawing area?

[martyn 2 russell bt com]

Im not completely sure if it will work in this case, but you should be able
to do it similarly to how glade does it.  With glade they create a
GtkTooltips and set a tip for each object which is a child of the window,
eg:

        GtkWidget *mywindow = ...
        GtkWidget *mydrawingarea = ...

        GtkTooltips *mytooltips = gtk_tooltips_new();
        
        gtk_tooltips_set_tip(mytooltips,mydrawingarea,"this is a
tooltip",NULL);

        .
        .       /* set tips for other widgets here */
        .
        
        /* set to the GtkObject of the window */
        gtk_object_set_data(GTK_OBJECT(mywindow),"tooltips",tooltips);

I dont know if this helps; there is more information in this at:
http://developer.gnome.org/doc/API/gtk/gtktooltips.html
