WDL/SWELL: SetWindowLong: Which messages do MacOS/Linux windows receive?

[juliansader]

On Windows, SetWindowLongPtr with the GWLP_WNDPROC argument can set a new window procedure to receive (and block or pass through) window messages. These messages range from mouse events such as WM_MOUSEWHEEL and WM_LBUTTONDOWN to keyboard events WM_KEYDOWN and many others

WDL/SWELL offers the SetWindowLong function, with the note:

** GWL_WNDPROC is supported by SWELL created windows/dialogs/controls, using 
** (int)getSwellWindowProc and setSwellWindowProc:(int).

If SetWindowLong with GWL_WNDPROC is used on MacOS/Linux, which message types can the new window procedure expect to receive? Do they use the same codes as on Windows, and the same wParams and lParams?

I hope that the WDL/SWELL version will at the very least receive mouse and mousewheel events.

It's important to note that this is only for SWELL-created windows, not necessarily controls (that comment is a bit misleading, perhaps). So if the window was created with CreateDialog() etc. The messages the window procedure will receive will be similar to the original window procedure/dialog procedure of the window (WM_LBUTTONDOWN etc sure). The same codes as Windows are used, though it is a subset (and there are some slight differences in some of them).

On MacOS/Linux, are REAPER's own windows, script GUIs and child windows such as "trackview" and "midiview" created via SWELL?

Are the WM_ types that are listed in "swell-types.h" the ones that have been implemented?
