563 | The Mac has only one global menubar, so we attempt to install the currently | |
564 | active menubar from a frame, we currently don't take into account mdi-frames | |
565 | which would ask for menu-merging | |
566 | ||
567 | Secondly there is no mac api for changing a menubar that is not the current | |
568 | menubar, so we have to wait for preparing the actual menubar until the | |
569 | wxMenubar is to be used | |
570 | ||
571 | We can in subsequent versions use MacInstallMenuBar to provide some sort of | |
572 | auto-merge for MDI in case this will be necessary | |
