| | 523 | Mac Implementation note : |
| | 524 | |
| | 525 | The Mac has only one global menubar, so we attempt to install the currently |
| | 526 | active menubar from a frame, we currently don't take into account mdi-frames |
| | 527 | which would ask for menu-merging |
| | 528 | |
| | 529 | Secondly there is no mac api for changing a menubar that is not the current |
| | 530 | menubar, so we have to wait for preparing the actual menubar until the |
| | 531 | wxMenubar is to be used |
| | 532 | |
| | 533 | We can in subsequent versions use MacInstallMenuBar to provide some sort of |
| | 534 | auto-merge for MDI in case this will be necessary |
| | 535 | |
