使Qt中的Splitter不能移动的设置方法

m_tableSplitter = new QSplitter(Qt::Horizontal, this);  
//... 假设已经有两个Widget放到里面。  
m_tableSplitter->setStyleSheet("QSplitter::handle { background-color: black }");  
QSplitterHandle *splitterHandle = m_tableSplitter->handle(1);  
if(splitterHandle)  
{  
    //Disable the Middle Line, it can't adjust.  
    splitterHandle->setDisabled(true);  
}
