Calling the TranslateAccelerator Function

To process accelerators, an application's (or thread's) message loop must contain a call to the TranslateAccelerator function. TranslateAccelerator compares keystrokes to an accelerator table and, if it finds a match, translates the keystrokes into a WM_COMMAND (or WM_SYSCOMMAND) message. The function then sends the message to a window procedure. The parameters of the TranslateAccelerator function include the handle of the window that is to receive the WM_COMMAND messages, the handle of the accelerator table used to translate accelerators, and a pointer to an MSG structure containing a message from the queue. The following example shows how to call TranslateAccelerator from within a message loop.

while (GetMessage(&msg, (HWND) NULL, 0, 0)) {

/* Check for accelerator keystrokes. */

if (!TranslateAccelerator(

hwndMain, /* handle of receiving window */

haccel, /* handle of active accel. table */

&msg)) { /* address of message data */

TranslateMessage(&msg);

DispatchMessage(&msg);

}

}
