布局怎么清空？以便重布

布局如何清空？以便重布！

C/C++ code

void AddrBookDlg::createNewTable (){    //表格delete又new了    SECURE_DELETE (m_ptableContacts);    m_ptableContacts = new AddrBookTableWidget ();    //重新加载    m_phlayoutAddrBookTable->deleteAllItems(); //???    m_phlayoutAddrBookTable->addWidget(m_ptableContacts);    m_phlayoutAddrBookTable->addStretch();}

查了下，
void QLayout::deleteAllItems () [protected]
Removes and deletes all items in this layout.

功能是所需要的，可惜是protected，访问不了！

[解决办法]
Qt再到的例子 Layout 文件里面有动态布局。。。自己去看吧！！！
