怎么一改活动窗口标题栏 非活动窗口标题栏就跟着改呢？？？

参考了一些文章。
我的方法是处理WM_NCPAINT等几个非客户区消息,这些
消息处理之后都要调用缺省函数DefWindowProc(),因此
重载DefWindowProc虚函数.
对话框属性有 Tool Window 去掉System Menu
LRESULT CTitleDlg::DefWindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
LRESULT lt=CDialog::DefWindowProc(message, wParam, lParam);
if(::IsWindow(m_hWnd))
{
if(message==WM_NCPAINT||
message==WM_NCACTIVATE||
message==WM_NOTIFY||
message==WM_SETTEXT)
{
CDC *pDC=GetWindowDC();
if(pDC)
{
CRect rtWnd, rtTitle;
GetWindowRect(&rtWnd);
rtTitle.left=GetSystemMetrics(SM_CXFRAME);
rtTitle.top=GetSystemMetrics(SM_CYFRAME);
rtTitle.right=rtWnd.right-rtWnd.left-
GetSystemMetrics(SM_CYFRAME);
rtTitle.bottom=rtTitle.top +
GetSystemMetrics(SM_CYSMCAPTION)-1;
//现在已经获得DC和RECT,可以随意在标题栏上画
CBrush br;
CPen pen(PS_SOLID,1,RGB(255,255,0));
br.CreateSolidBrush(RGB(255,255,0));
int save=pDC->SaveDC();
pDC->SelectObject(&pen);
pDC->SelectObject(&br);
pDC->Rectangle(rtTitle);//画矩形
//画一个标准最小化按钮
pDC->DrawFrameControl(CRect(4,4,15,14),
DFC_CAPTION,DFCS_CAPTIONMIN);
//照上还可以画最大和关闭标准按钮
pDC->RestoreDC(save);
ReleaseDC(pDC);
}
}
}
return lt;
}
处理鼠标按下消息
........
先判断是哪个按钮,再作相应的处理,例如:
最大化和恢复按钮: if(IsZoomed())
SendMessage(WM_SYSCOMMAND,SC_RESTORE,
MAKELPARAM(point.x,point.y));
else
SendMessage(WM_SYSCOMMAND,SC_MAXIMIZE,
MAKELPARAM(point.x,point.y));
最小化按钮: SendMessage(WM_SYSCOMMAND,SC_MINIMIZE,
MAKELPARAM(point.x,point.y));
关闭按钮: SendMessage(WM_CLOSE);
