再探MFC(五)状态栏

创建和初始化状态栏

step1

对话框添加变量

// 状态栏对象

CStatusBarm_wndStatusBar;

step2

OnInitDialog调用

//创建和初始化状态栏

BOOLCLBDKFODlg::CreateStatusBar()

{

static UINT nIndicators[] = {

ID_CALL_STATUS

};

if (!m_wndStatusBar.Create (this))

return FALSE;

m_wndStatusBar.SetIndicators (nIndicators,1);

CRectrect;

GetClientRect(&rect);

m_wndStatusBar.SetPaneInfo(0,ID_CALL_STATUS,SBPS_NORMAL,rect.Width());

//m_wndStatusBar.GetStatusBarCtrl().SetBkColor(RGB(180,180,180));

RepositionBars(AFX_IDW_CONTROLBAR_FIRST,AFX_IDW_CONTROLBAR_LAST,ID_CALL_STATUS);

return TRUE;

}

注意在资源文件中定义ID_CALL_STATUS.

更新状态栏文本

m_wndStatusBar.SetPaneText(0,"空闲");

To create a status bar, follow these steps:

1. Construct the CStatusBar object.

1. Call the Create (or CreateEx)
   function to create the status-bar window and attach it to the CStatusBar object.

1. Call SetIndicators to associate a string ID with each indicator.

There are three ways to update the text in a status-bar pane:

1. Call CWnd::SetWindowText to update the text in pane 0 only.

1. Call CCmdUI::SetText in the status bar‘s ON_UPDATE_COMMAND_UI handler.

1. Call SetPaneText to update the text for any pane.
