示例1: switch
LRESULT CALLBACK
WindowProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
// Note, this window's message handling should not invoke any call that
// may result in a cross-process ipc call. Doing so may violate RPC
// message semantics.
switch (msg) {
case WM_GETOBJECT:
{
// Do explicit casting to make it working on 64bit systems (see bug 649236
// for details).
int32_t objId = static_cast<DWORD>(lParam);
if (objId == OBJID_CLIENT) {
DocAccessible* document =
nsWinUtils::sHWNDCache->GetWeak(static_cast<void*>(hWnd));
if (document) {
