Introduction
The Real-Player program inserts its logo between the caption bar and menu bar. If you ever wanted to do this, then just follow me. :)
- Create a dialog based project (need not care whether SDI or MDI)
Project name: Fake Real Player
- Insert your Logo bitmap file in your project.
Logo name: IDB_LOGO
- To make room for drawing your logo, insert a temporary menu item in your default menu resource like 'menu for Image' at the first position.
resource ID: IDM_IMAGE
, no popup menu
- Enlarge your
IDM_IMAGE
menu width to make room for logo in the OnMeasureItem()
method:
void CFakeRealDlg::OnMeasureItem(int nIDCtl,
LPMEASUREITEMSTRUCT lpMeasureItemStruct)
{
if (lpMeasureItemStruct->CtlType == ODT_MENU)
{
if (lpMeasureItemStruct->itemID == IDM_IMAGE)
lpMeasureItemStruct->itemWidth =
m_rectLogo.Width() + 5;
}
CDialog::OnMeasureItem(nIDCtl,
lpMeasureItemStruct);
}
- Load your Logo bitmap file in your
OnInitDialog()
method.
m_hBmp = (HBITMAP)LoadImage(AfxGetInstanceHandle(),
MAKEINTRESOURCE(IDB_LOGO), IMAGE_BITMAP,
0, 0, LR_CREATEDIBSECTION);
BITMAP bm;
GetObject(m_hBmp, sizeof(bm), &bm);
m_rectLogo.left = 15;
m_rectLogo.right = 15 + bm.bmWidth;
m_rectLogo.top = 2 ;
m_rectLogo.bottom = 2 + bm.bmHeight;
- Make a
DrawLogo()
method to paint your Logo Bitmap
.
void CFakeRealDlg::DrawLogo()
{
CDC* pdc= GetWindowDC();
CDC memdc;
memdc.CreateCompatibleDC(pdc);
memdc.SelectObject(m_hBmp);
pdc->BitBlt(15, 2,
m_rectLogo.Width(),
m_rectLogo.Height(),
&memdc, 0, 0, SRCCOPY);
ReleaseDC(pdc);
}
- Override your
OnInitMenu()
method and OnSystemMenu()
to protect Window draw line between the caption bar and the menu bar.
void CFakeRealDlg::OnInitMenu(CMenu* pMenu)
{
CDialog::OnInitMenu(pMenu);
DrawLogo();
}
void CFakeRealDlg::OnSysCommand(UINT nID,
LPARAM lParam)
{
if ((nID & 0xFFF0) == IDM_ABOUTBOX)
{
CAboutDlg dlgAbout;
dlgAbout.DoModal();
}
else
{
DrawLogo();
CDialog::OnSysCommand(nID, lParam);
}
}
- Override your
OnNcPaint()
to paint your Logo whenever FakeReal is shown.
void CRealDlg::OnNcPaint()
{
Default();
DrawLogo();
}
Steps 1~8 show you what you must do, but you may want to perfect this sample. For example, you may want to add an owner-draw caption to hide the system icon. If you upgrade this sample, I'll be very happy. Have a nice day!!!
