CWaitCursor::Restore

若要還原等待游標，請在執行作業完成之後會呼叫這個函式，例如顯示訊息方塊或 對話方塊中，可能會變更等待游標為另一個資料指標。

void Restore( );

備註

即使等待游標目前顯示，可以呼叫 還原 。

如果您在函式需要還原等待游標，當 CWaitCursor 宣告物件的執行個體時，您可以呼叫 CCmdTarget::RestoreWaitCursor。

範例

// This example illustrates performing an operation 
// which changes the wait cursor. You should call 
// CWaitCursor::Restore to restore the wait 
// cursor after an operation which changes the cursor.
void AnotherLengthyFunction( )
{
   CWaitCursor wait;   // display wait cursor

   // do some lengthy processing
   Sleep(1000);

   // The dialog box will normally change the cursor to
   // the standard arrow cursor.
   CFileDialog dlg(TRUE);
   dlg.DoModal();

   // It is necessary to call Restore here in order
   // to change the cursor back to the wait cursor.
   wait.Restore();

   // do some more lengthy processing
   Sleep(1000);

   // destructor automatically removes the wait cursor
}

// If the wait cursor is changed by a function called by
// the function which created the wait cursor, you 
// can call CCmdTarget::RestoreWaitCursor to restore 
// the wait cursor.
void CalledFunction()
{
   CFileDialog dlg(TRUE);
   dlg.DoModal();

   // Since CWinApp is derived from CCmdTarget, we can use a 
   // pointer to our application object to make the call to
   // CCmdTarget::RestoreWaitCursor.
   AfxGetApp()->RestoreWaitCursor();

   // Yet more lengthy processing...
   Sleep(1000);
}
