set_cursor
Description:
Sets the default mouse pointer for a `GdkSurface`.
Passing null for the cursor argument means that this will use
the cursor of its parent surface. Most surfaces should use this default. Note that cursor must be for the same display as
this.
Use [ctor@Gdk.Cursor.new_from_name] or [ctor@Gdk.Cursor.new_from_texture] to create the cursor. To make the cursor invisible, use gdk_blank_cursor.
Parameters:
| this |
a `GdkSurface` |
| cursor |
a `GdkCursor` |
