本文介绍了一种通过模拟键盘事件来实现电话号码输入并启动拨号界面的方法。具体步骤包括清除拨号面板上已有的号码、逐位输入指定的电话号码，并最终通过模拟确认按键触发拨号界面的显示。

直接调用ShowStandBy()函数即可把KPhoneNumber设置到拨号对话框中

//显示待机桌面
void CWorldContainer::ShowStandBy()
    {

    CCoeEnv* env = CCoeEnv::Static();

    const TUid KUidPhoneApp =
        {
        0x100058B3
        };
    RWsSession& ws = env->WsSession();
    TApaTaskList tl(ws);
    TApaTask task = tl.FindApp(KUidPhoneApp);
    if (task.Exists())
        {
        TInt wgId = task.WgId();
        SendEventL(ws, wgId, EKeyDevice1, EStdKeyDevice1); // first clear the numbers (if any) in dial panel
        _LIT(KPhoneNumber, "1234567890");
        TInt len = KPhoneNumber().Length();
        for (TInt i = 0; i < len; i++)
            {
            SendEventL(ws, wgId, KPhoneNumber()[i], KPhoneNumber()[i]); // then "input" the phone number
            }
        }

    // and then launch the dial pad
    TKeyEvent event;
    event.iCode = EKeyYes;
    event.iScanCode = EStdKeyYes;
    env->SimulateKeyEventL(event, EEventKeyDown);
