get_windows

Gets the list of Window on this.

The list is not in a defined order, but should be "stable" (windows should not be reordered in it). However, the stability of the list is established by the window manager, so don't blame libwnck if it breaks down.

Parameters:

this

a Screen.

Returns:

the list of Window on this, or null if there is no window on this. The list should not be modified nor freed, as it is owned by this.
