Windows Mobile Phone全屏開發

一般來講，通過函數SHFullScreen就可以實現，如通過如下調用SHFullScreen(hWnd, SHFS_HIDETASKBAR | SHFS_HIDESIPBUTTON | SHFS_HIDESTARTICON)即可實現，但有一個注意點，如果你的窗口裏有MENU Bar 的話，則需要在全屏幕的時候隱藏MENU Bar可以調用SHGetMenuBar()來獲取MENU的句柄，這裏不能直接將HMENU用CAST成HWND,然後再使用ShowWindow(hWndMenu, SW_HIDE)來隱藏Menu。這樣就是全屏的窗口了，返回非全屏模式，也是調用SHFullScreen()來實現，只是把裏面的標誌位置換成SHOW的就好。下面是例子代碼:



BOOL rb;
BOOL chgScreen;
int rc;
RECT rect;
HWND hWnd;

rb = SystemParametersInfo(SPI_GETWORKAREA, 0, &rect, 0);
if (rb == FALSE)  // SystemParametersInfo failed.
{
    rc = MessageBox(NULL, _T("Could not get work area."),
                    _T("Error"), MB_OK);
    if (rc == 0)  // Not enough memory to create MessageBox.
        return E_OUTOFMEMORY;
    return E_FAIL;  // Replace with specific error handling.
}

hWnd = CreateWindow(szWindowClass, szTitle, WS_VISIBLE,
       CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
       CW_USEDEFAULT, NULL, NULL, hInstance, NULL);
if (hWnd == NULL)// CreateWindow failed.
{
    rc = MessageBox(NULL, _T("Could not create main window."),
                    _T("Error"), MB_OK);
    if (rc == 0)  // Not enough memory to create MessageBox.
        return E_OUTOFMEMORY;
    return E_FAIL;  // Replace with specific error handling.
}

GetWindowRect(hWnd, &rect);
chgScreen = SHFullScreen(hWnd, SHFS_HIDETASKBAR | SHFS_HIDESIPBUTTON |
                  SHFS_HIDESTARTICON);
if (chgScreen == FALSE);
{
    // SHFullScreen failed.
    rc = MessageBox(NULL, _T("Could not modify the window."),
                    _T("Error"), MB_OK);
    if (rc == 0)  // Not enough memory to create MessageBox.
        return E_OUTOFMEMORY;
    return E_FAIL;  // Replace with specific error handling.
}
MoveWindow( hWnd,
            rect.left,
            rect.top - MENU_HEIGHT,
            rect.right,
            rect.bottom + MENU_HEIGHT,
            TRUE);

1. //隱藏任務欄
2. HWND lpClassName;
3. lpClassName = ::FindWindow(TEXT("HHTaskBar"), NULL);
4. ::ShowWindow(lpClassName, SW_HIDE);

複製代碼

我的應用程序需要在運行時全屏化，所以使用SHFullScreen來實現，不過我發現總是一個輸入法欄無法隱藏，請參見附件中的截圖，不知是何故。我的運行平臺爲Windows Mobile 5.0 ppc，代碼如下：

BOOL CTestDlg::OnInitDialog()
{
........

     DWORD dwState = ( SHFS_HIDETASKBAR | SHFS_HIDESTARTICON | SHFS_HIDESIPBUTTON );
     SHFullScreen( m_hWnd, dwState );

     CRect rc;
     SetRect( &rc, 0, 0, GetSystemMetrics( SM_CXSCREEN ),
         GetSystemMetrics( SM_CYSCREEN ) );
     MoveWindow( &rc, TRUE );

.........
}
