Subject: [PATCH] Resolves: rhbz#1021915 force menubar menus to be up/down only
|
|
|
|
If a menu won't fit in the desired location the default mode is to place it
|
|
somewhere it will fit. e.g. above, left, right. For some cases, e.g. menubars,
|
|
it's desirable to limit the options to above/below and force the menu to scroll
|
|
if it won't fit
|
|
