一、定义资源:
二、定义全局变量及函数:
CRect m_rtButtExit; //关闭按钮位置 CRect m_rtButtMax; //最大化按钮位置 CRect m_rtButtMin; //最小化按钮位置 CRect m_rtButtHelp; //帮助按钮位置 CRect m_rtIcon; //图标位置 void DrawTitleBar(CDC *pDC); //画非客户区主函数
三、函数实现:void CTitleBarDlg::DrawTitleBar(CDC *pDC)
{
if (m_hWnd)
{
CBrush Brush(RGB(0,100,255));
CBrush* pOldBrush = pDC->SelectObject(&Brush);
CRect rtWnd, rtTitle, rtButtons;
GetWindowRect(&rtWnd);
……………………………..
//因代码过长,未贴,见源程序
……………………………...
}
}
//将消息进行过滤,对可能影响界面初始及更新的消息,产生重画消息执行DrawTitleBar函数
LRESULT CTitleBarDlg::DefWindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
LRESULT lrst=CDialog::DefWindowProc(message, wParam, lParam);
if (!::IsWindow(m_hWnd))
return lrst;
if (message==WM_MOVE||message==WM_PAINT||message==WM_NCPAINT||
message== WM_NCACTIVATE ||message == WM_NOTIFY)
{
CDC* pWinDC = GetWindowDC();
if (pWinDC)
DrawTitleBar(pWinDC);
ReleaseDC(pWinDC);
}
return lrst;
}
//实现标题栏按钮的鼠标移动效果
void CTitleBarDlg::OnNcMouseMove(UINT nHitTest, CPoint point)
{
CDC* pDC = GetWindowDC();
if (pDC)
{
……………………………..
//因代码过长,未贴,见源程序
……………………………...
}
ReleaseDC(pDC);
CDialog::OnNcMouseMove(nHitTest, point);
}
//实现非客户区,用户鼠标点击操作
void CTitleBarDlg::OnNcLButtonDown(UINT nHitTest, CPoint point)
{
//检测各按钮是否按到
if (m_rtIcon.PtInRect(point))
AfxMessageBox("欢迎访问FlySnowStdio主页");
else if (m_rtButtHelp.PtInRect(point))
SendMessage(WM_HELP);
else if (m_rtButtExit.PtInRect(point))
SendMessage(WM_CLOSE);
else if (m_rtButtMin.PtInRect(point))
SendMessage(WM_SYSCOMMAND, SC_MINIMIZE, MAKELPARAM(point.x, point.y));
else if (m_rtButtMax.PtInRect(point))
{
if (IsZoomed())
SendMessage(WM_SYSCOMMAND, SC_RESTORE, MAKELPARAM(point.x, point.y));
else
{
SendMessage(WM_SYSCOMMAND, SC_MAXIMIZE, MAKELPARAM(point.x, point.y));
Invalidate();
}
}
else if (!IsZoomed())
Default();
}
四、总结
