MFC allows you to easily add status bars to CFrameWnd-derived windows. However, if you want to add a status bar to a dialog, you're going to find the going just a bit more difficult.
Basically, it turned out that I had to dig very deep into the MFC documentation in order to find anything to help me out. One example I found is by ZEKSER Cyril. His techniques works fine, but (IMHO) is not very "clean" since you have to place an invisible static object on the dialog as a kind of placeholder for the status bar. However, I do want to thank him very much for showing me the light at the end of the tunnel.
The technique I came up with works like this: First, you need to develop your dialog (and define its CDialog-based class). Nothing new here so far.
Then, insert the following code into the CDialog::OnInitDialog function (the m_StatBar variable is of type CStatusBarCtrl).
BOOL CMyDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon
/************************************************************************/
/* Adding STATUSBAR */
/************************************************************************/
int nTotWide; // total width of status bar
CRect rect;
this->GetWindowRect(&rect);
rect.top = rect.bottom- 25;
m_bRvStatOk = m_StatBar.Create(WS_CHILD | WS_BORDER | WS_VISIBLE ,rect,this,
IDC_STATUSBAR);
if (m_bRvStatOk == NULL)
{
AfxMessageBox ("Status Bar not created!", NULL, MB_OK );
}
//
// get size of window, use to configure the status
// bar with four separate parts
//
CRect rWin;
this->GetWindowRect(&rWin);
nTotWide = rWin.right-rWin.left;
//
// Make each part 1/4 of the total width of the window.
//
m_Widths[0] = nTotWide / 4;
m_Widths[1] = nTotWide / 2;
m_Widths[2] = nTotWide - m_Widths[0];
m_Widths[3] = -1;
m_StatBar.SetMinHeight(25);
m_StatBar.SetParts( 4, m_Widths);
//
// now lets put some text, different styles into parts of status bar
//
m_StatBar.SetText("WITH BORDER.", 0,0);
m_StatBar.SetText("WITHOUT BORDER.",1,SBT_NOBORDERS);
m_StatBar.SetText("POPUP.",2,SBT_POPOUT);
//
// make the last part owner-drawn, add a bitmap
//
m_StatBar.SetText(NULL,3, SBT_OWNERDRAW);
// hBmp is a Global Variable of type HBITMAP
hBmp = ::LoadBitmap(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_BITMAP1));
/************************************************************************/
/* End STATUSBAR */
/************************************************************************/
// TODO: Add extra initialization here
return TRUE; // return TRUE unless you set the focus to a control
}
The fourth pane of the status bar is owner drawn because it is used to display a bitmap. In order to do this, simply add a message handler for the dialog's WM_DRAWITEM message. Once you've added that function, update it so that when finished it looks like the following.
void CMyDlg::OnDrawItem(int nIDCtl, LPDRAWITEMSTRUCT lpDrawItemStruct)
{
//
// Draw bitmap in status bar
//
HDC hdcMem; // device context for memory
HGDIOBJ hbmOld; // old bitmap area we're over-writing
BITMAP bm; // bitmap we're using
//
// Create a compatible DC in memory
//
hdcMem = CreateCompatibleDC(lpDrawItemStruct->hDC);
// Select the "logo.bmp" bitmap into the DC.
hbmOld = ::SelectObject(hdcMem, hBmp);
// Get the size of the bitmap
::GetObject(hBmp, sizeof(bm), &bm);
// Blt the bitmap to the part.
BitBlt(lpDrawItemStruct->hDC,lpDrawItemStruct->rcItem.left,
lpDrawItemStruct->rcItem.top, bm.bmWidth, bm.bmHeight,
hdcMem, 0, 0,SRCCOPY);
//
// Add some text..1st. get bounding rectangle, then position & display text
//
char szText[16];
RECT rText; // text rectangle
rText.left = lpDrawItemStruct->rcItem.left+24;
rText.top = lpDrawItemStruct->rcItem.top;
rText.right = lpDrawItemStruct->rcItem.right-20;
rText.bottom = lpDrawItemStruct->rcItem.bottom;
//
// add some text after the logo bitmap here
//
memset(szText,0,sizeof(szText));
strcpy(szText,"LOGO"); // text to draw
SelectObject( lpDrawItemStruct->hDC, GetStockObject( ANSI_VAR_FONT ) );
::SetBkColor(lpDrawItemStruct->hDC, 0x00c0c0c0); // set background color
ExtTextOut(lpDrawItemStruct->hDC, lpDrawItemStruct->rcItem.left+24, lpDrawItemStruct->rcItem.top+4, ETO_OPAQUE, &rText, szText,
strlen(szText),NULL ); // draw the text in the rectangle rText
//
// End adding text. Reselect the original object into the DC.
//
SelectObject(hdcMem, hbmOld);
// Delete the compatible DC.
DeleteDC(hdcMem);
}
Make the following changes to the dialog's header file.
class CMyDlg : public CDialog
{
// Construction
public:
CMyDlg(CWnd* pParent = NULL); // standard constructor
CStatusBarCtrl m_StatBar;
.....................................
...................................
......................................
}
CStatusBarCtrl m_StatBar;
.....................................
...................................
......................................
}
Finally, make the following changes to the resource.h file.
//{{NO_DEPENDENCIES}}
// Microsoft Developer Studio generated include file.
//
#define IDM_ABOUTBOX 0x0010
#define IDC_STATUSBAR 32500
.....................................
...................................
......................................That's it! You now have a status bar at the bottom of your dialog!
