MTY_WMsgFunc

Function called to add custom processing to window messages.

This function is called before any internal processing, and if shouldReturn is set to true, no internal handling of the message will take place. This may affect internal state tracking for certain message types.

typedef intptr_t (*MTY_WMsgFunc)(
    MTY_App *  app,
    MTY_Window window,
    void *     hwnd,
    uint32_t   msg,
    intptr_t   wparam,
    uintptr_t  lparam,
    bool *     shouldReturn,
    void *     opaque
);

Parameters

app (MTY_App *)

The MTY_App.

window (MTY_Window)

The MTY_Window associated with the message.

hwnd (void *)

HWND hwnd value passed as the first argument to the WNDPROC callback.

msg (uint32_t)

UINT uMsg value passed as the second argument to the WNDPROC callback.

wparam (intptr_t)

WPARAM wParam value passed as the third argument to the WNDPROC callback.

lparam (uintptr_t)

LPARAM lParam value passed as the fourth argument to the WNDPROC callback.

shouldReturn (bool *)

If set to true, no internal processing of this message will take place and the return value from this callback will be returned by the internal WNDPROC callback.

opaque (void *)

Pointer set via MTY_AppCreate.

Return value

intptr_t

Function called to add custom processing to window messages.
