43 NB: This is not a header file, dispite the file name suffix. This file is |
|
44 included directly into the source code of qcocoawindow_mac.mm and |
|
45 qcocoapanel_mac.mm to avoid manually doing copy and paste of the exact |
|
46 same code needed at both places. This solution makes it more difficult |
|
47 to e.g fix a bug in qcocoawindow_mac.mm, but forget to do the same in |
|
48 qcocoapanel_mac.mm. |
|
49 The reason we need to do copy and paste in the first place, rather than |
|
50 resolve to method overriding, is that QCocoaPanel needs to inherit from |
|
51 NSPanel, while QCocoaWindow needs to inherit NSWindow rather than NSPanel). |
