|
|
|
41 to the user-specified-position vs. program-specified-position and
|
|
|
42 user-specified-size vs. program-specified-size flag. (It always
|
|
|
43 sets program-specified whenever the program requests a change
|
|
|
44 in its size or position, even when this came from direct user
|
|
|
45 request.) So we provide external entry points to fix this after
|
|
|
46 the program requested a size or position change. If it turns
|
|
|
47 out that the user-specified-position flag needs to be set at the
|
|
|
48 *same* time that the geometry change request is made, then we
|
|
|
49 will have to duplicate the entire root_geometry_manager() method;

|

50 but I don't think there are any WM's that require this. */
