Change cursor

[Andreas Volz <lists brachttal net>]

Hi,

I like to change the cursor to a clock and after I did something back
to normal. I call the function from inside a Gtk::Window class member
function. I tried this:

  Glib::RefPtr<Gdk::Window> gdk_window = get_frame ();
  const Gdk::Cursor cursor (Gdk::CLOCK);
  gdk_window.set_cursor (cursor);

The first both lines compile great, but the second fail:

MeasureDialog.cpp:176: error: `set_cursor' undeclared (first use this
function)

But yelp give this help:

 void Gdk::Window::set_cursor  	(  	const Cursor&
	 cursor  	 ) 

Sets the mouse pointer for a Gdk::Window.

To make the cursor invisible, use gdk_cursor_new_from_pixmap() to
create a cursor with no pixels in it.

Parameters:
    	cursor 	A cursor.

So what's wrong? What should I do?

regards
Andreas
