MFC对话框中添加状态栏的方法
本文实例讲述了MFC对话框中添加状态栏的方法。分享给大家供大家参考。具体如下：
1.在对话框的dlg实现类里添加成员变量：
CXTPStatusBarm_wndStatusBar;
//状态栏（或者是CStatusBar）
//在OnInitDialog方法中初始化：
staticUINTindicators[]=
{
ID_SEPARATOR,//statuslineindicator
ID_INDICATOR_CAPS,
ID_INDICATOR_NUM,
ID_INDICATOR_SCRL,
};
//添加状态栏
if(!m_wndStatusBar.Create(this)||
!m_wndStatusBar.SetIndicators(indicators,
sizeof(indicators)/sizeof(UINT)))
{
TRACE0("Failedtocreatestatusbar\n");
return-1;//failtocreate
}
2.添加OnKickIdle事件(在对话框的dlg的头文件加上)：
afx_msgLRESULTOnKickIdle(WPARAM,LPARAM); afx_msgvoidOnUpdateKeyIndicator(CCmdUI*pCmdUI); DECLARE_MESSAGE_MAP()
3.在实现类中添加对应的两个方法：
LRESULTCDialogPanesDlg::OnKickIdle(WPARAM,LPARAM)
{
m_wndStatusBar.SendMessage(WM_IDLEUPDATECMDUI,TRUE);
return0;
}
voidCDialogPanesDlg::OnUpdateKeyIndicator(CCmdUI*pCmdUI)
{
UINTnVK;
UINTflag=0×0001;
switch(pCmdUI->m_nID)
{
caseID_INDICATOR_CAPS:
nVK=VK_CAPITAL;
break;
caseID_INDICATOR_NUM:
nVK=VK_NUMLOCK;
break;
caseID_INDICATOR_SCRL:
nVK=VK_SCROLL;
break;
default:
TRACE1("Warning:OnUpdateKeyIndicator–unknownindicator0x%04X.\n",
pCmdUI->m_nID);
pCmdUI->ContinueRouting();
return;//notforus
}
pCmdUI->Enable(::GetKeyState(nVK)&flag);
//enablestatictextbasedontoggledkeystate
ASSERT(pCmdUI->m_bEnableChanged);
}
4.运行发现看不见状态栏，添加对话框的WM_SIZE事件：
voidCDialogPanesDlg::OnSize(UINTnType,intcx,intcy)
{
CDialog::OnSize(nType,cx,cy);
//TODO:Addyourmessagehandlercodehere
CRectrcClient(0,0,cx,cy);
RepositionBars(0,0xffff,AFX_IDW_PANE_FIRST,0,0,&rcClient);
RepositionBars(0,0xffff,AFX_IDW_PANE_FIRST,reposQuery,&rcClient,&rcClient);
}
希望本文所述对大家的MFC程序设计有所帮助。
