示例1: PRECONDITION
//
/// Calls TWindow::GetFocus() to determine the window with the focus. Searches the
/// list of documents and returns the document that contains the view with the
/// focus. Returns 0 if no document has a view with focus.
//
TDocument*
TDocManager::GetCurrentDoc()
{
PRECONDITION(GetApplication());
PRECONDITION(GetApplication()->GetMainWindow());
HWND hWnd = GetApplication()->GetMainWindow()->GetCommandTarget();
TDocument* doc = 0;
#if defined(OLD_DOCVIEW)
// !BB This older implementation of GetCurrentDoc relies on the
// !BB document's HasFocus method which does not allow 'GetCurrentDoc'
// !BB to return child documents....
// !BB
// !BB This obviously causes some problems (for example, closing a view
// !BB associated with a child document closes the whole document and
// !BB all their associated views!).
// !BB
// !BB However is there code that relies on this behaviour - Investigate
// !BB
if (hWnd && ::IsWindow(hWnd)) {
