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