427 Mac Implementation note :
428
429 The Mac has only one global menubar, so we attempt to install the currently
430 active menubar from a frame, we currently don't take into account mdi-frames
431 which would ask for menu-merging
432
433 Secondly there is no mac api for changing a menubar that is not the current
434 menubar, so we have to wait for preparing the actual menubar until the
435 wxMenubar is to be used
436
437 We can in subsequent versions use MacInstallMenuBar to provide some sort of
438 auto-merge for MDI in case this will be necessary
