Applet Framework

The new applet hook function signature will look like this:

AwnApplet* awn_applet_factory_init( gchar* uid, gint orient, gint height );

Your applet's implementation of this function will be responsible for creating itself and returning itself so it can be added to the AWN dock. Your applet will be required to extend AwnApplet via the GObject way.

Simple Example (non-inheritance way):

AwnApplet* awn_applet_factory_init ( gchar* uid, gint orient, gint height ) {
    AwnApplet *applet = awn_applet_new( uid, orient, height );
    gtk_widget_set_size_request (GTK_WIDGET (applet), 5, height * 2);

    g_signal_connect (G_OBJECT (applet), "expose-event", G_CALLBACK (expose), NULL);

    return applet;
}

static gboolean expose (GtkWidget *widget, GdkEventExpose *event, gpointer null) {
    cairo_t *cr = NULL;

    cr = gdk_cairo_create (widget->window);
    if (!cr)
            return FALSE;

    /* Clear the background to transparent */
    cairo_set_source_rgba (cr, 1.0f, 1.0f, 1.0f, 0.0f);
    cairo_set_operator (cr, CAIRO_OPERATOR_CLEAR);
    cairo_paint (cr);

    /* Clean up */
    cairo_destroy (cr);

    return TRUE;
}
