对支持玻璃的应用

使用WTLAppWizard创建简单FirstTest应用:只需在向导的第一个屏幕上点击下一步,取选"使用视图"框,然后点击"完成".现在搞一些简单的更改,总是要完成这些步骤:

1,更改stdafx.h中的常数:

 //`stdafx.h`:标准系统包含文件,或常用但不经常更改的项目
#pragma once
//更改这些值以使用不同版本
#define WINVER           0x0600
#define _WIN32_WINNT     0x0600
#define _WIN32_IE        0x0700
#define _RICHEDIT_VER    0x0200
//...

2,从WtlAero.zip提取toolbar.bmp,到FirstTest\res\项目目录中.

3,从WtlAero.zip提取WtlAero.h到FirstTest\项目目录中,并更改FirstTest.cpp以包含它:

//`FirstTest.cpp`:`FirstTest.exe`的主源文件
#include "stdafx.h"
#include<atlframe.h>
#include <atlctrls.h>
#include <atldlgs.h>
#include <atlctrlw.h>
#include "WtlAero.h"//..
#include "resource.h"
//...

4,在MainFrm.h中,按它们的aero::对应项更改CFrameWindowImpl和m_CmdBar的定义:

 //`MainFrm.h:CMainFrame`类的接口
#pragma once
class CMainFrame : public aero::CFrameWindowImpl<CMainFrame>,
    public CUpdateUI<CMainFrame>,
    public CMessageFilter, public CIdleHandler
{
public:
    DECLARE_FRAME_WND_CLASS(NULL, IDR_MAINFRAME)
    CFirstTestView m_view;
    aero::CCommandBarCtrl m_CmdBar;//..
//...

5,更改消息映射中的基类定义,并在OnCreate()处理器前移动它:

BEGIN_MSG_MAP(CMainFrame)
 CHAIN_MSG_MAP(aero::CFrameWindowImpl<CMainFrame>)//..
MESSAGE_HANDLER(WM_CREATE, OnCreate)
 MESSAGE_HANDLER(WM_DESTROY, OnDestroy)
 COMMAND_ID_HANDLER(ID_APP_EXIT, OnFileExit)
 COMMAND_ID_HANDLER(ID_FILE_NEW, OnFileNew)
 COMMAND_ID_HANDLER(ID_VIEW_TOOLBAR, OnViewToolBar)
 COMMAND_ID_HANDLER(ID_VIEW_STATUS_BAR, OnViewStatusBar)
 COMMAND_ID_HANDLER(ID_APP_ABOUT, OnAppAbout)
 CHAIN_MSG_MAP(CUpdateUI<CMainFrame>)
END_MSG_MAP()

6,如果要在XP或W2k下运行应用,请为uxtheme.dll和dwmapi.dll设置懒加载

就这样.编译并运行.应该就行了.

用第一个测试做更多的事情:

1,按透明工具栏更改工具栏,只需在CMainFrame::OnCreate()中替换调用CreateSimpleToolBarCtrl()即可:

HWND hWndToolBar = CreateAeroToolBarCtrl(m_hWnd,
 IDR_MAINFRAME,FALSE,ATL_SIMPLE_TOOLBAR_PANE_STYLE);//..

要一些绘画,请在CMainFrame中插入此成员:

void Paint(CDCHandle dc, RECT& rClient, RECT& rView, RECT& rDest)
{
    CLogFont lf;
    GetThemeSysFont(TMT_MSGBOXFONT, &lf);
    lf.lfHeight *= 3;
    CFont f = lf.CreateFontIndirect();
    HFONT hfOld = dc.SelectFont(f);
    DrawText(dc, L"Hello Aero", &rClient, DT_CENTER | DT_VCENTER | DT_SINGLELINE);
    dc.SelectFont(hfOld);
 }

取"Aero"对话框

1,在资源编辑器中,打开IDD_ABOUTBOX对话框,并按IDC_APPICON和IDC_APPTEXT更改图标和文本控件ID.

2,更改aboutdlg.h中的代码:

//`aboutdlg.h:CAboutDlg`类的接口...
class CAboutDlg : public aero::CDialogImpl<CAboutDlg >//..
{
public:
    enum { IDD = IDD_ABOUTBOX };
    BEGIN_MSG_MAP(CAboutDlg)
        CHAIN_MSG_MAP(aero::CDialogImpl<CAboutDlg >)//..
        MESSAGE_HANDLER(WM_INITDIALOG, OnInitDialog)
        COMMAND_ID_HANDLER(IDOK, OnCloseCmd)
        COMMAND_ID_HANDLER(IDCANCEL, OnCloseCmd)
    END_MSG_MAP()
//...
    LRESULT OnInitDialog(UINT /*`uMsg`*/, WPARAM /*`wParam`*/,
        LPARAM /*l参数*/, BOOL& /*b已处理*/)
    {
        CenterWindow(GetParent());
        AERO_CONTROL(CStatic, m_Icon, IDC_APPICON)//<<
        AERO_CONTROL(CStatic, m_Text, IDC_APPTEXT)
        AERO_CONTROL(CButton, m_OK, IDOK)//>>
        return TRUE;
    }
//`...`

玻璃示例

在AeroSamples项目中,你可找到其他适合玻璃的AppWizard应用:

1,AeroFrame与你的FirstTest相同

2,AeroView使用简单的WTL视图类.CMainFrame和CAboutDlg的更改相同,CAeroView::Paint()也可在无主题运行时环境中工作.

 //`AeroView.h:CAeroView`类的接口`
class CAeroView : public aero::CWindowImpl<CAeroView>//..
{
public:
    DECLARE_WND_CLASS(NULL)
    BOOL PreTranslateMessage(MSG* pMsg)
    {
        pMsg;
        return FALSE;
    }
    void Paint(CDCHandle dc, RECT& rClient, RECT& rView, RECT& rDest)
    {
        CLogFont lf;
        if (IsTheming())
        {
            GetThemeSysFont(TMT_MSGBOXFONT, &lf);
            if (!aero::IsSupported())
                DrawThemeBackground(dc, 1, 1, &rClient, &rDest);
        }
        else
        {
            NONCLIENTMETRICS ncm = { sizeof(NONCLIENTMETRICS) };
            SystemParametersInfo ( SPI_GETNONCLIENTMETRICS, sizeof(NONCLIENTMETRICS), &ncm, false );
            lf = ncm.lfMessageFont;
            dc.FillSolidRect(&rClient, GetSysColor(COLOR_WINDOW));
        }
        lf.lfHeight *= 3;
        CFont f = lf.CreateFontIndirect();
        HFONT hfOld = dc.SelectFont(f);
        DrawText(dc, L"Hello Aero", &rClient,
           DT_CENTER | DT_VCENTER | DT_SINGLELINE);
        dc.SelectFont(hfOld);
    }
    BEGIN_MSG_MAP(CAeroView)
        CHAIN_MSG_MAP(aero::CWindowImpl<CAeroView>)//..
    END_MSG_MAP()
};

3,AeroTab是一个使用相同,aero::CTabView替换了CTabView的CAeroView类的"AppWizard选项卡视图应用".

4,AeroSplit与MainFrm.h中向导生成的代码相比,有更多变化.

class CMainFrame : public aero::CFrameWindowImpl<CMainFrame>,//..
   public CUpdateUI<CMainFrame>,
   public CMessageFilter, public CIdleHandler
{
public:
    DECLARE_FRAME_WND_CLASS(NULL, IDR_MAINFRAME)
    aero::CSplitterWindow m_splitter;
    aero::CPaneContainer m_pane;
    aero::CCtrl<CTreeViewCtrl> m_treeview;
    CAeroView m_view;
    aero::CCommandBarCtrl m_CmdBar;
//`...`
    LRESULT OnCreate(UINT /*`uMsg`*/, WPARAM /*`wParam`*/, LPARAM /*l参数*/,
        BOOL& /*b已处理*/)
    {
//...
      m_treeview.SetWindowTheme(L"explorer", NULL);
      HTREEITEM hti = m_treeview.InsertItem(L"Test", TVI_ROOT, TVI_LAST);
      m_treeview.InsertItem(L"Child Test", hti, TVI_LAST);
//...

5,AeroDialog是一个在对话框编辑器中,添加了一些控件的"模态对话框AppWizard应用".

 //`MainDlg.h:CMainDlg`类的接口`
#pragma once
class CMainDlg : public aero::CDialogImpl<CMainDlg>//..
{
public:
    enum { IDD = IDD_MAINDLG };
    BEGIN_MSG_MAP(CMainDlg)
        CHAIN_MSG_MAP(aero::CDialogImpl<CMainDlg>)//..
//...
    LRESULT OnInitDialog(UINT /*`uMsg`*/, WPARAM /*`wParam`*/, LPARAM /*l参数*/, BOOL& /*b已处理*/)
    {
    //...
        AERO_CONTROL(CButton, m_OK, IDOK)//<<
        AERO_CONTROL(CButton, m_Cancel, IDCANCEL)
        AERO_CONTROL(CButton, m_About, ID_APP_ABOUT)
        AERO_CONTROL(CEdit, m_Edit, IDC_EDIT1)
        AERO_CONTROL(CButton, m_C1, IDC_CHECK1)
        AERO_CONTROL(CButton, m_C2, IDC_CHECK2)
        AERO_CONTROL(CButton, m_R1, IDC_RADIO1)
        AERO_CONTROL(CButton, m_R2, IDC_RADIO2)
        AERO_CONTROL(CButton, m_Group, IDC_GROUP)
        AERO_CONTROL(CListBox, m_LB, IDC_LIST1)
        AERO_CONTROL(CComboBox, m_CB, IDC_COMBO1)//>>
        m_LB.AddString(L"TEST Item");
        m_CB.AddString(L"Combo Test");
        SetOpaqueUnder(IDC_MONTHCALENDAR1);
        return TRUE;
    }
//...

WTL::aero名字空间内部

WTL::aero名字空间提供了支持玻璃的WTL应用的工具集.

名间函数

这些函数运行时测试,允许后向兼容.

1,bool aero::IsSupported():如果为false,则不试内容.

2,bool aero::IsComposing():如果这是真,请继续.

3,bool aero::IsOpaqueBlend():如果为true,则关闭Vista透明度

4,template <class TCtrl>BOOL aero::Subclass(TCtrl&Ctrl,HWND hCtrl)仅在aero::IsSupported()时,用TCtrl类型的Ctrl子类化hCtrl控件.

基类

基类是库的引擎.

1,aero::CAeroBase为其继承类提供访问主题API的权限.Subclass()成员接受控件ID并在其HWND上调用aero::Subclass().

在半透明背景上绘画时,各种DrawText()成员都使用::DrawThemeTextEx().

//`aero::CAeroBase`,(如果可用)`Aero`半透明基类
template <class T>
class CAeroBase :
    public WTL::CThemeImpl<T>
{
public:
    CAeroBase(LPCWSTR lpstrThemeClassList = L"globals")
    {
        SetThemeClassList(lpstrThemeClassList);
    }
    bool IsTheming() const
    {
        return m_hTheme != 0;
    }
    template <class TCtrl>
    BOOL Subclass(TCtrl& Ctrl, INT idCtrl)
    {
        return aero::Subclass(Ctrl,
            static_cast<T*>(this)->GetDlgItem(idCtrl));
    }
    bool DrawPartText(HDC dc, int iPartID, int iStateID,
        LPCTSTR pStr, LPRECT prText, UINT uFormat, DTTOPTS &dto)
    {
        HRESULT hr = S_FALSE;
        if(IsTheming())
            if (IsSupported())
                hr = DrawThemeTextEx (dc, iPartID, iStateID, pStr, -1, uFormat, prText, &dto );
            else
                hr = DrawThemeText(dc, iPartID, iStateID, pStr, -1, uFormat, 0, prText);
        else
            hr = CDCHandle(dc).DrawText(pStr, -1, prText, uFormat) != 0 ?  S_OK : S_FALSE;
        return SUCCEEDED(hr);
    }
     bool DrawPartText(HDC dc, int iPartID, int iStateID, LPCTSTR pStr,
        LPRECT prText, UINT uFormat,
        DWORD dwFlags = DTT_COMPOSITED, int iGlowSize = 0)
    {
        DTTOPTS dto = {sizeof(DTTOPTS)};
        dto.dwFlags = dwFlags;
        dto.iGlowSize = iGlowSize;
        return DrawPartText(dc, iPartID, iStateID, pStr, prText, uFormat, dto);
    }
    bool DrawText(HDC dc, LPCTSTR pStr, LPRECT prText, UINT uFormat, DTTOPTS &dto)
    {
        return DrawPartText(dc, 1, 1, pStr, prText, uFormat, dto);
    }
    bool DrawText(HDC dc, LPCTSTR pStr, LPRECT prText, UINT uFormat, DWORD dwFlags = DTT_COMPOSITED, int iGlowSize = 0)
    {
        return DrawPartText(dc, 1, 1, pStr, prText, uFormat, dwFlags, iGlowSize);
    }
};

1,aero::CAeroImpl从CAeroBase和WTL::CBufferedPaintImpl继承,并通过其m_Margins成员管理半透明区域.

2,SetMargins()和各种SetOpaque()成员允许控件半透明区域.

3,CBufferedPaintImpl::OnPaint()用系统缓冲的DC调用DoPaint()成员.

4,它依次调用继承类Paint(CDCHandledc,RECT&rClient,RECT&rView,RECT&rDest),其中rClient是窗口客户矩,rView是外边距内的区域,rDest是绘画区域.

//`aero::CAeroImpl`,(如果可用)`Aero`半透明实现
template <class T>
class CAeroImpl :
    public WTL::CBufferedPaintImpl<T>,
    public CAeroBase<T>

            SUCCEEDED(DwmExtendFrameIntoClientArea (pT->m_hWnd, &m_Margins)) : true;
    }
    bool SetOpaque(bool bOpaque = true)
    {
        MARGINS m = {bOpaque - 1};
        return SetMargins(m);
    }

        pT->GetClientRect(&rClient);
        MARGINS m = {rOpaque.left, rClient.right - rOpaque.right, rOpaque.top, rClient.bottom - rOpaque.bottom};
        return SetMargins(m);
    }

        RECT rView = {rClient.left + m_Margins.cxLeftWidth,
            rClient.top + m_Margins.cyTopHeight,
            rClient.right - m_Margins.cxRightWidth,

            else
                dc.FillSolidRect(&rClient, ::GetSysColor(COLOR_MENUBAR));
        if ((m_Margins.cxLeftWidth != -1) && !::IsRectEmpty(&rView))

        return bHandled = FALSE;

适配器类

这些类给现有控件加上AeroGlass效果.

用aero::CCtrl来子类化系统和常见控件.

两个成员来特化:GetThemeName()返回创建或子类化时要打开的控件的主题名,通过覆盖的OnBufferedPaint()成员绘画CtrlPaint(HDChdc,RECT&rCtrl,RECT&rPaint)调用.

三个DrawCtrlxxx()成员是特定绘图例程的助手.
AERO_CONTROL()宏帮助一步声明和子类化子控件.

aero::CCtrlImpl在现有TCtrlImpl上启用玻璃绘图.可在继承类中覆盖DoPaint()成员,以调用TCtrlImpl相关代码.

 //`aero::CCtrlImpl`,对用户和`WTL`定义的控件,实现`玻璃`绘图,注意:从此类继承
template <class T, class TCtrlImpl, bool t_bOpaque = false>
class ATL_NO_VTABLE CCtrlImpl :
    public TCtrlImpl,
    public CAeroImpl<T>
{
public:
    DECLARE_WND_SUPERCLASS(NULL, TCtrlImpl::GetWndClassName())
    CCtrlImpl(LPCWSTR lpstrThemeClassList = L"window") : CAeroImpl(lpstrThemeClassList)
    {
        m_PaintParams.dwFlags = BPPF_ERASE;
    }
    void DoPaint(HDC hdc, RECT& rect)
    {
        BOOL bHandled = TRUE;
        TCtrlImpl::OnPaint(WM_PAINT, (WPARAM) hdc, NULL, bHandled);
        if (t_bOpaque)
            m_BufferedPaint.MakeOpaque(&rect);
    }
    BEGIN_MSG_MAP(CCtrlImpl)
        CHAIN_MSG_MAP(CAeroImpl<T>)
        CHAIN_MSG_MAP(TCtrlImpl)
    END_MSG_MAP()
};

替换类

这些是启用玻璃的类,用来替换同名的WTL::或ATL::类.
可继承类:这些类从aero::CAeroImpl继承:

aero::CWindowImpl< T, TBase, TWinTraits >
aero::CDialogImpl<T, TBase>
aero::CFrameWindowImpl<T, TBase, TWinTraits>
aero::CPropertySheetImpl<T, TBase>
aero::CPropertyPageImpl<T, TBase>
aero::CSplitterImpl<T, t_bVertical>
aero::CSplitterWindowImpl<T, t_bVertical, TBase, TWinTraits>
aero::CSplitterWindowT<t_bVertical>

从aero::CCtrl,继承或特化的类:

aero::CEdit
aero::CTabCtrl
aero::CToolBarCtrl
aero::CStatusBarCtrl
aero::CListBox
aero::CComboBox
aero::CStatic
aero::CButton

从aero::CCtrlImpl继承的类:

aero::CCommandBarCtrl
aero::CTabView
aero::CPaneContainer
aero::CPrintPreviewWindow

结论

在现有本地代码应用上启用漂亮的Aeroglass并不难.干杯!
