430Mac Implementation note :
431
432The Mac has only one global menubar, so we attempt to install the currently
433active menubar from a frame, we currently don't take into account mdi-frames
434which would ask for menu-merging
435
436Secondly there is no mac api for changing a menubar that is not the current
437menubar, so we have to wait for preparing the actual menubar until the
438wxMenubar is to be used
439
440We can in subsequent versions use MacInstallMenuBar to provide some sort of
441auto-merge for MDI in case this will be necessary
