怎样重画标题栏？

楼主snaill（com.chinaos.snaill）2003-08-01 18:37:57 在 VC/MFC / 界面提问

如题
但关键是，
如何取道标题栏图标的rect,标题的rect？
如何得到关闭，极大化，极小化按钮的Rect及窗体句柄？问题点数：100、回复次数：9Top

用不着得到，自己全画就可以了 WM_NCPAINTTop

我在WM_NCPAINT做了操作，在关闭按钮附近点击时，仍能看到关闭按钮被显示出来，不知是哪里的代码重画的

另外我想让我重画的关闭，极大化，极小化按钮能够使用缺省的window事件，不知如何实现？Top

重载CMainFrame类的DefWindowProc()函数，并判断消息为：WM_NCPAINT,WM_NCACTIVATE,WM_NOTIFY的时候，调用自己的绘制窗口标题栏的函数.
用GetSystemMetrics(SM_CSFRAME);和GetSystemMetrics(SM_CYFRAME)；可以取得标题栏的左上角的坐标。最大化，最小化的按钮自己画就可以了，如果不是在标准的位置，一定要记录下他们的位置，并且在WM_NCLBUTTONDOWN消息处理函数中判断是否是点击了按钮，以做出相应的处理。系统图标也可以自己重新画。
如果要是对话框的话，还有一个方法，就是不要标题栏，然后在顶部放置一个Static控件和几个Button控件，然后重绘这几个控件做成标题栏的样子。当然这要看你的绘图技术好不好了（这方法我还没用过，只是见别人用过)Top

本例以对话框应用程序为基础，自画非客户区，完成应用程序美化,代码运行效果图如下:

下面我们来探讨具体的实现过程

一、定义资源：
　　添加系统按钮的位图资源（本例中使用十个位图，分别显示帮助、最小化、最大化、恢复及关闭按钮的普通状态和焦点状态，当然可随程序的要求自定义添加）
　　
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：
　　本例需要对以下消息进行重载DefWindowProc、ON_WM_NCMOUSEMOVE、ON_WM_NCLBUTTONDOWN。
　　函数实现体如下：
//主函数，可根据实际情况进行自绘窗体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
本例为对话框应用程序，单文档的基本原理也相似。对于包含菜单项的程序，可以采用自画菜单，将整个程序的界面融为一体，在此不做过多介绍，本人已经完成，请与我联系。如果你想使你的程序更漂亮，也可以尽情放至贴图到背景上，愿你的程序多姿多彩。本文是在百忙中匆匆完成，错误之处希望大家批评指正！
