on_message

Type

Remarks:

• This function pointer can be used to call the engine message loop from another window's message loop. The parameters are the same as for window messages; a description can be found in the Windows API documentation.
• As long as the engine window exists, this pointer must never be set to NULL. Otherwise the engine can't react anymore on Windows messages.

Edition:

Example (lite-C):

#include <acknex.h>
#include <windows.h>

LRESULT CALLBACK OriginalHandler(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam);

LRESULT CALLBACK MyMessageHandler(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
   if (WM_SIZE == message)
   { 
       printf("Resize attempt!");
       return 1;
   }
   return OriginalHandler(hwnd,message,wParam,lParam);   	  
}

function main() 
{
   OriginalHandler = on_message;	// store the original message loop
   on_message = MyMessageHandler; // and replace it by your own
   ...
}
