在CStageButton類的實(shí)現(xiàn)代碼中，設(shè)置當(dāng)鼠標(biāo)按下時(shí)觸發(fā)的云臺(tái)控制代碼和鼠標(biāo)抬起時(shí)停止對(duì)云臺(tái)的控制。代碼如下：

//當(dāng)按下鼠標(biāo)按鈕時(shí)，根據(jù)按鈕的類型標(biāo)識(shí)調(diào)用不同的方法

void CStageButton::OnLButtonDown(UINT nFlags, CPoint point) 

{

switch(m_Type)

{

case ctUp:

{

((CCaptureDlg*)GetParent())->OnUp(); //控制云臺(tái)向上

break;

}

case ctDown:

{

((CCaptureDlg*)GetParent())->OnDown(); //控制云臺(tái)向下

break;

}

case ctLeft:

{

((CCaptureDlg*)GetParent())->OnLeft(); //控制云臺(tái)向左

break;

}

case ctRight:

{

((CCaptureDlg*)GetParent())->OnRight(); //控制云臺(tái)向右

break;

}

case ctInFoci:

{

break;

}

case ctReFoci:

break;

}

case ctInLen:

break;

}

case ctReLen:

break;

}

case ctInAperture:

{

break;

}

case ctReAperture:

{

break;

}

case ctInBrush:

}

}

}

//當(dāng)釋放鼠標(biāo)按鈕時(shí)停止對(duì)云臺(tái)的控制
