修改菜单Menu、工具栏ToolBar、状态栏StatusBar的背景色

修改菜单Menu的背景色

在头文件中声明：HBRUSH m_hMenuBrush;
CMainFrame::OnCreate中添加：

m_hMenuBrush = CreateSolidBrush(#c8c8c8); // 菜单颜色
::MENUINFO lpcmi;
memset(&lpcmi, 0, sizeof(::LPCMENUINFO));
lpcmi.cbSize = sizeof(MENUINFO);
lpcmi.fMask = MIM_APPLYTOSUBMENUS | MIM_BACKGROUND;
lpcmi.hbrBack = m_hMenuBrush;
::SetMenuInfo(GetMenu()->m_hMenu, &lpcmi);

最后：if (m_hMenuBrush) { DeleteObject(m_hMenuBrush); m_hMenuBrush = NULL; }

修改工具栏Toolbar的背景色：

取消stdafx.h中的visual style的效果，否则看不到效果
继承CToolBar，并响应WM_ERASEBKGND，添加以下代码

// 改变背景色
CRect ClientRect;
GetClientRect(ClientRect);
pDC->FillSolidRect(ClientRect, #6575a9); // #6575a9:修改后的颜色
return TRUE;

最后，修改MainFrm.h中的m_wndToolBar为继承后的类对象

ReBar在2010中未试验成功，在vc6中可以看到效果。

另外，以下两句会使程序中所有Toolbar的背景色都改变：
HBRUSH newBr = CreateSolidBrush(#6575a9);
DWORD dwRet = SetClassLongW(m_wndToolBar1.m_hWnd, GCL_HBRBACKGROUND, (long)newBr);

修改状态栏StatusBar的背景色

取消stdafx.h中的visual style的效果，否则看不到效果
修改背景色：m_wndStatusBar.GetStatusBarCtrl().SetBkColor(#00005a);
修改状态栏提示Text的颜色：

继承CStatusBar类为CColorStatusBar，重载DrawItem，

void CColorStatusBar::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct/**/)
{
    // TODO: Add your code to draw the specified item

    // Attach to a CDC object
    CDC dc;
    dc.Attach(lpDrawItemStruct->hDC);

    dc.SetBkMode(TRANSPARENT);

    // Get the pane rectangle and calculate text coordinates
    CRect rect(&lpDrawItemStruct->rcItem);

    if (lpDrawItemStruct->itemID < m_nColumnNum)
    {
        dc.SetTextColor(m_pColor[lpDrawItemStruct->itemID]);
        dc.TextOut(rect.left+2, rect.top, m_pcstrText[lpDrawItemStruct->itemID]);
    }

    // Detach from the CDC object, otherwise the hDC will be
    // destroyed when the CDC object goes out of scope
    dc.Detach();
}
其中：m_pColor为COLORREF的指针，CColorStatusBar的成员变量，存储状态栏各列的颜色
     m_pcstrText为CString的指针，CColorStatusBar的成员变量，存储状态栏各列的字符

使用CColorStatusBar时，要改变状态栏的提示内容时，需调用m_wndColorStatusBar.GetStatusBarCtrl().SetText(L"", nID, SBT_OWNERDRAW);触发DrawItem函数被调用。

4. 修改状态栏右边的缩放区域的背景色，响应WM_PAINT消息

void CColorStatusBar::OnPaint()

{
    //CPaintDC dc(this); // device context for painting
    // TODO: Add your message handler code here
    // Do not call CStatusBar::OnPaint() for painting messages

    CStatusBar::OnPaint();

    CClientDC dc(this); // class CClientDC : public CDC
    if (!GetParent()->IsZoomed()) DrawSizing(&dc);
}
void CColorStatusBar::DrawSizing(CDC *pDC)
{
    CRect rect;
    GetWindowRect(&rect);
    rect.OffsetRect(-rect.left, -rect.top);

    if (m_hSizingBkBrush)
    {
        pDC->SelectObject(m_hSizingBkBrush);
        pDC->Rectangle(rect.right-18, rect.bottom-18, rect.right, rect.bottom);
    }
    if (m_hSizingPen)
    {
        pDC->SelectObject(m_hSizingPen);
        pDC->MoveTo(rect.right - 5, rect.bottom);
        pDC->LineTo(rect.right,        rect.bottom - 5);
        pDC->MoveTo(rect.right - 9, rect.bottom);
        pDC->LineTo(rect.right,        rect.bottom - 9);
        pDC->MoveTo(rect.right - 13, rect.bottom);
        pDC->LineTo(rect.right,        rect.bottom - 13);
    }
}
其中m_hSizingBkBrush、m_hSizingPen均为CcolorStatusBar的成员变量。
