int CXindowView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CView::OnCreate(lpCreateStruct) == -1)
return -1;
/* 创建左右两个视图 */
m_pForm = (CXindowForm *) okCreateView(RUNTIME_CLASS(CXindowForm), 1001);
m_pList = (CXindowList *) okCreateView(RUNTIME_CLASS(CXindowList), 1002);
m_pForm->m_pParent = this;
return 0;
} 当窗口宽度<400时,会隐藏左边的CXindowForm视图: void CXindowView::OnSize(UINT nType, int cx, int cy)
{
CView::OnSize(nType, cx, cy);
int nFormWidth = 200;
/* 如果窗口宽度<400, 就隐藏左视图 */
if(cx>400)
{
if(m_pForm->GetSafeHwnd()) m_pForm->ShowWindow(SW_SHOW);
if(m_pForm->GetSafeHwnd()) m_pForm->MoveWindow(0,0,nFormWidth,cy);
if(m_pList->GetSafeHwnd()) m_pList->ShowWindow(SW_SHOW);
if(m_pList->GetSafeHwnd()) m_pList->MoveWindow(nFormWidth,0,cx-nFormWidth,cy);
}
else
{
if(m_pForm->GetSafeHwnd()) m_pForm->ShowWindow(SW_HIDE);
if(m_pList->GetSafeHwnd()) m_pList->ShowWindow(SW_SHOW);
if(m_pList->GetSafeHwnd()) m_pList->MoveWindow(0,0,cx,cy);
}
}其中左边的的CXindowForm视图中有个CXLabel控件“增加”,点击会产生WM_NOFITY消息,这样就能够响应了。 void CXindowForm::OnInitialUpdate()
{
CFormView::OnInitialUpdate();
/* 相当于CListCtrl::SetItemData(), 用于区别是哪个CXLabel */
m_add.SetCommand(1);
}
BOOL CXindowForm::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
LPNMHDR pnmh = (LPNMHDR) lParam;
if(pnmh->code==NM_LINKCLICK)
{
CXLabel* pLabel = (CXLabel *)GetDlgItem(pnmh->idFrom);
CString str;
/* GetCommand() */
str.Format("d",pLabel->GetCommand());
AfxMessageBox(str);
if(m_pParent->GetSafeHwnd())
{
CListCtrl& listCtrl = ((CXindowView*)m_pParent)->m_pList->GetListCtrl();
int nCount = listCtrl.GetItemCount();
int nItem = listCtrl.InsertItem(nCount, "2003-8-15");
listCtrl.SetItemText(nItem, 1, "192.168.3.1");
listCtrl.SetItemText(nItem, 2, "");
listCtrl.SetItemText(nItem, 3, "编程");
}
}
return CFormView::OnNotify(wParam, lParam, pResult);
} 注:CXLabel控件来自CLabel类,增加了几个有效函数。
