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

1. 在头文件中声明：HBRUSH m_hMenuBrush;
2. 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：

1. 取消stdafx.h中的visual style的效果，否则看不到效果
2. 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

网上关于ReBar的介绍：

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

1. 取消stdafx.h中的visual style的效果，否则看不到效果
2. 修改背景色：m_wndStatusBar.GetStatusBarCtrl().SetBkColor(#00005a);
3. 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。
