Desktop screenshot

[Andy Bell <andy bell allbabel com>]

Hi,

I am trying to get a screenshot of the desktop by using a transparent GtkWidget and then using gdk_pixbuf_get_from_drawable.   When I check the saved GdkPixbuf I am getting a valid image, but the image does not include the background of the desktop but just the GtkWidget itself.  Is there any way of working around this?

I am simply creating a GtkWidget and then controlling the paint events, the code for the paint and saving the image is below:

static gboolean on_window_expose_event(GtkWidget *widget, GdkEventExpose *event, gpointer data)

{

  cairo_t *cr;

  cr = gdk_cairo_create(widget->window); // create cairo context

  cairo_set_source_rgba(cr, 1.0, 1.0, 1.0, 0.7);

  cairo_set_operator(cr, CAIRO_OPERATOR_SOURCE); 

  cairo_paint(cr); // paint source

  cairo_destroy(cr);

  static int >

  if ( 0 )

  {

 GdkPixbuf * pixbuf;

 pixbuf = gdk_pixbuf_get_from_drawable( NULL, widget->window, colormap, 0, 0, 0, 0, 300, 200 );

  if ( pixbuf != NULL )

 {

 GError * err = NULL;

 gdk_pixbuf_save( pixbuf, "image.png", "png", &err, NULL );

 }

 once++;

  }

  return FALSE;

}

Thanks, Andy.
