WM_FONTCHANGE message

An application sends the WM_FONTCHANGE message to all top-level windows in the system after changing the pool of font resources.

To send this message, call the SendMessage function with the following parameters.

SendMessage( 
  (HWND)  hWnd,              
  WM_FONTCHANGE,            
  (WPARAM)  wParam,          
  (LPARAM)  lParam            
);

Parameters

lParam

Remarks

An application that adds or removes fonts from the system (for example, by using the AddFontResource or RemoveFontResource function) should send this message to all top-level windows.

To send the WM_FONTCHANGE message to all top-level windows, an application can call the SendMessage function with the hwnd parameter set to HWND_BROADCAST.
