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