MFC對話框中添加狀態欄的方法

MFC對話框中添加狀態欄的方法,這篇文章主要介紹了MFC對話框中添加狀態欄的方法,實例分析了MFC對話框添加狀態欄所涉及的相關成員變量與事件實現技巧,需要的朋友可以參考下
關鍵字:MFC、對話框、狀態欄

本文實例講述了MFC對話框中添加狀態欄的方法。分享給大家供大家參考。具體如下:

1.在對話框的dlg實現類里添加成員變量:

CXTPStatusBar m_wndStatusBar; 
//狀態欄(或者是CStatusBar)
//在OnInitDialog方法中初始化:
static UINT indicators[] =
{
ID_SEPARATOR, // status line indicator
ID_INDICATOR_CAPS,
ID_INDICATOR_NUM,
ID_INDICATOR_SCRL,
};
//添加狀態欄
if (!m_wndStatusBar.Create(this) ||
!m_wndStatusBar.SetIndicators(indicators,
sizeof(indicators)/sizeof(UINT)))
{
TRACE0("Failed to create status bar\n");
return -1; // fail to create
}

2.添加OnKickIdle事件(在對話框的dlg的頭文件加上) :

afx_msg LRESULT OnKickIdle(WPARAM, LPARAM);
afx_msg void OnUpdateKeyIndicator(CCmdUI* pCmdUI);
DECLARE_MESSAGE_MAP()

3.在實現類中添加對應的兩個方法:

LRESULT CDialogPanesDlg::OnKickIdle(WPARAM, LPARAM)
{
m_wndStatusBar.SendMessage(WM_IDLEUPDATECMDUI, TRUE);
return 0;
}
void CDialogPanesDlg::OnUpdateKeyIndicator(CCmdUI* pCmdUI)
{
UINT nVK;
UINT flag = 0×0001;
switch (pCmdUI->m_nID)
{
case ID_INDICATOR_CAPS:
nVK = VK_CAPITAL;
break;
case ID_INDICATOR_NUM:
nVK = VK_NUMLOCK;
break;
case ID_INDICATOR_SCRL:
nVK = VK_SCROLL;
break;
default:
TRACE1("Warning: OnUpdateKeyIndicator – unknown indicator 0x%04X.\n",
pCmdUI->m_nID);
pCmdUI->ContinueRouting();
return; // not for us
}
pCmdUI->Enable(::GetKeyState(nVK) & flag);
// enable static text based on toggled key state
ASSERT(pCmdUI->m_bEnableChanged);
}

4.運行發現看不見狀態欄,添加對話框的WM_SIZE事件:

void CDialogPanesDlg::OnSize(UINT nType, int cx, int cy)
{
CDialog::OnSize(nType, cx, cy);
// TODO: Add your message handler code here
CRect rcClient(0, 0, cx, cy);
RepositionBars(0, 0xffff, AFX_IDW_PANE_FIRST, 0, 0, &rcClient);
RepositionBars(0, 0xffff, AFX_IDW_PANE_FIRST, reposQuery, &rcClient, &rcClient);
}

希望本文所述對大家的MFC程序設計有所幫助。
