 439 Mac Implementation note :
 440
 441 The Mac has only one global menubar, so we attempt to install the currently
 442 active menubar from a frame, we currently don't take into account mdi-frames
 443 which would ask for menu-merging
 444
 445 Secondly there is no mac api for changing a menubar that is not the current
 446 menubar, so we have to wait for preparing the actual menubar until the
 447 wxMenubar is to be used
 448
 449 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 450 auto-merge for MDI in case this will be necessary
