c - 如何为 Win32 应用程序启用工具栏的现代外观？

Question

最近开始学习基于Win32 API的GUI编程。当我将工具栏控件(来自 comctl32.lib)添加到我的简单应用程序时，我发现它看起来很平坦，而菜单栏具有更多“Windows 7 友好”的 3D 外观和感觉(顶部的白色发光和从上到下的垂直灰色渐变)。差异使它看起来有线。

但是，我发现许多其他应用程序的菜单栏和工具栏具有一致的外观。例如。 Notepad++和 Notepad 2 .

看了一些官方文档，尝试了解决方案，比如Visual Styles Overview , Enabling Visual Styles但是，它只启用平面按钮样式(与旧的 Win98 实心按钮样式相比)。这与我在第一张图片中获得的样式没有任何区别。

我试图阅读 Notepad++ 的源代码。找到ToolBar.cpp并相应地对我的代码进行了一些更改，但没有任何改变。我想我迷失在代码库中了。

这是我调用 InitCommonControlsEx 和创建工具栏的代码。

// in WinMain
INITCOMMONCONTROLSEX icce;
icce.dwSize = sizeof(INITCOMMONCONTROLSEX);
icce.dwICC = ICC_BAR_CLASSES | ICC_COOL_CLASSES | ICC_USEREX_CLASSES;
InitCommonControlsEx(&icce);

// called in WM_CREATE handler, hwnd is the handle of the main window
VOID BuildToolBar(HWND hwnd)
{
    HWND hTool;
    TBBUTTON tbb[3];
    TBADDBITMAP tbab;

    hTool = CreateWindowEx(0, TOOLBARCLASSNAME, NULL, WS_CHILD | WS_VISIBLE | WS_CLIPCHILDREN | WS_CLIPSIBLINGS | TBSTYLE_TOOLTIPS |TBSTYLE_FLAT | CCS_TOP | BTNS_AUTOSIZE, 0, 0, 0, 0, hwnd, (HMENU)IDC_MAIN_TOOL, GetModuleHandle(NULL), NULL);
    SendMessage(hTool, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);
    SendMessage(hTool, TB_SETEXTENDEDSTYLE, 0, (LPARAM)TBSTYLE_EX_HIDECLIPPEDBUTTONS);

    tbab.hInst = HINST_COMMCTRL;
    tbab.nID = IDB_STD_SMALL_COLOR;
    SendMessage(hTool, TB_ADDBITMAP, 0, (LPARAM)&tbab);

    ZeroMemory(tbb, sizeof(tbb));
    tbb[0].iBitmap = STD_FILENEW;
    tbb[0].fsState = TBSTATE_ENABLED;
    tbb[0].fsStyle = TBSTYLE_BUTTON;
    tbb[0].idCommand = ID_FILE_NEW;

    tbb[1].iBitmap = STD_FILEOPEN;
    tbb[1].fsState = TBSTATE_ENABLED;
    tbb[1].fsStyle = TBSTYLE_BUTTON;
    tbb[1].idCommand = ID_FILE_OPEN;

    tbb[2].iBitmap = STD_FILESAVE;
    tbb[2].fsState = TBSTATE_ENABLED;
    tbb[2].fsStyle = TBSTYLE_BUTTON;
    tbb[2].idCommand = ID_FILE_SAVEAS;

    SendMessage(hTool, TB_SETBUTTONSIZE, (WPARAM)0, (LPARAM)MAKELONG(16, 16));
    SendMessage(hTool, TB_ADDBUTTONS, sizeof(tbb) / sizeof(TBBUTTON), (LPARAM)&tbb);
    SendMessage(hTool, TB_AUTOSIZE, 0, 0);
}

所以，问题是:尽管按钮有位图，但我怎样才能获得工具栏的 3D 外观，就像 Notepad++/Notepad2 示例一样？

提前致谢。

先创建Toolbar，再创建Rebar。

rbBand.hbmBack 必须设置为 NULL 以获得现代外观的工具栏，或者从下面的代码中删除 RBBIM_BACKGROUND 标志。

创建钢筋的方法如下:

HWND WINAPI CreateRebar (HWND hwndOwner)
{
    REBARINFO     rbi;
    REBARBANDINFO rbBand;
    RECT          rc;
    HWND   hwndCB, hwndRB;
    DWORD  dwBtnSize;

    hwndRB = CreateWindowExW(WS_EX_TOOLWINDOW,
        REBARCLASSNAME,
        NULL,
        WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS |
        WS_CLIPCHILDREN | RBS_VARHEIGHT |
        CCS_NODIVIDER,
        0, 0, 0, 0,
        hwndOwner,
        NULL,
        GetModuleHandleW(NULL),
        NULL);
    if (!hwndRB)
        return NULL;
    // Initialize and send the REBARINFO structure.
    rbi.cbSize = sizeof(REBARINFO);  // Required when using this
    // structure.
    rbi.fMask = 0;
    rbi.himl = (HIMAGELIST)NULL;
    if (!SendMessage(hwndRB, RB_SETBARINFO, 0, (LPARAM)&rbi))
        return NULL;
    // Initialize structure members that both bands will share.
    rbBand.cbSize = sizeof(REBARBANDINFO);  // Required
    rbBand.fMask = RBBIM_COLORS | RBBIM_TEXT | RBBIM_BACKGROUND |
        RBBIM_STYLE | RBBIM_CHILD | RBBIM_CHILDSIZE |
        RBBIM_SIZE;
    rbBand.fStyle = RBBS_CHILDEDGE | RBBS_FIXEDBMP;
    rbBand.hbmBack = NULL;  //
    // Create the combo box control to be added.
    hwndCB = CreateWindowW(TEXT("COMBOBOX"), NULL,
        WS_CHILD | WS_VISIBLE | CBS_HASSTRINGS | CBS_DROPDOWNLIST,
        410, 20, 120, 110, (HWND) NULL, NULL, NULL, NULL);;
    // Set values unique to the band with the combo box.
    GetWindowRect(hwndCB, &rc);
    rbBand.lpText = "Combo Box";
    rbBand.hwndChild = hwndCB;
    rbBand.cxMinChild = 0;
    rbBand.cyMinChild = rc.bottom - rc.top;
    rbBand.cx = 200;

    // Add the band that has the combo box.
    SendMessage(hwndRB, RB_INSERTBAND, (WPARAM)-1, (LPARAM)&rbBand);


    // Get the height of the toolbar.
    dwBtnSize = SendMessage(toolbar1, TB_GETBUTTONSIZE, 0, 0);

    // Set values unique to the band with the toolbar.
    rbBand.lpText = "Tool Bar";
    rbBand.hwndChild = toolbar1;
    rbBand.cxMinChild = 0;
    rbBand.cyMinChild = HIWORD(dwBtnSize);
    rbBand.cx = 250;

    // Add the band that has the toolbar.
    SendMessage(hwndRB, RB_INSERTBAND, (WPARAM)-1, (LPARAM)&rbBand);
    return (hwndRB);
}
