[求助]如何修改编辑文本框的边框颜色？

Question

////////// SkinTestDlg.h : header file
public:
   CBrush m_MeaningBrush; //背景颜色画刷////////// SkinTestDlg.cpp : implementation file
CSkinTestDlg::CSkinTestDlg(CWnd* pParent /*=NULL*/)
: CDialog(CSkinTestDlg::IDD, pParent)
{
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);

//创建为白色背景
m_MeaningBrush.CreateSolidBrush(RGB(255,255,255));
}BEGIN_MESSAGE_MAP(CSkinTestDlg, CDialog)
//{{AFX_MSG_MAP(CSkinTestDlg)
ON_WM_CTLCOLOR() //添加事件
//}}AFX_MSG_MAP
END_MESSAGE_MAP()//修改文本框背景颜色
HBRUSH CSkinTestDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
 HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

 //判断控件ID
 if (pWnd->GetDlgCtrlID() == IDC_EDIT1)
 {
   //设置背景色和字体颜色
   pDC->SetBkColor(RGB(255,255,255));
   pDC->SetTextColor(RGB(0,0,0)); //编辑框类的字体设置为黑色；
   //pDC->SetBkMode(TRANSPARENT); //设置为透明不影响字体颜色   //设置边框颜色
   CDC* dc = GetDC();   //获取画布对象
   CRect rect;
   GetClientRect(rect); //获取客户区域
   rect.InflateRect(1,1,1,1);    //将客户区域增大一个象素
   CBrush brush(RGB(255,255,0)); //创建画刷
   dc->FrameRect(rect,&brush);   //绘制边框 

   return (HBRUSH)m_MeaningBrush.GetSafeHandle();
   }

  return hbr;
}

Answer 1

感觉下面几行代码没起作用:
  //设置边框颜色
   CDC* dc = GetDC();   //获取画布对象
   CRect rect;
   GetClientRect(rect); //获取客户区域
   rect.InflateRect(1,1,1,1);    //将客户区域增大一个象素
   CBrush brush(RGB(255,255,0)); //创建画刷
   dc->FrameRect(rect,&brush);   //绘制边框

下面的代码只能修改窗体边框的颜色,
如何修改Edit文本框的边界颜色呢?HBRUSH CSkinTestDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
 HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
    
 //判断控件ID
 if (pWnd->GetDlgCtrlID() == IDC_EDIT1)
 {
//修改窗体边框的颜色
CDC *pDC = GetWindowDC();
CRect rcWnd;
GetWindowRect(rcWnd);
ScreenToClient(rcWnd);
int nWidht = rcWnd.Width();
int nHeight = rcWnd.Height();
rcWnd.left = 1;
rcWnd.top = 1;
rcWnd.bottom = rcWnd.top+nHeight-1;
rcWnd.right = rcWnd.left + nWidht-1;
CPen pen(PS_SOLID, 1, RGB(255, 0, 128));
HPEN Oldpen = (HPEN)pDC->SelectObject(pen);
pDC->Rectangle(rcWnd);
pDC->SelectObject(Oldpen);
ReleaseDC(pDC);

你要操作的时候Edit，因此窗口指针应该是编辑框的指针  HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

  // TODO: Change any attributes of the DC here
  if (pWnd->GetDlgCtrlID() == IDC_EDIT1)
  {
    //修改窗体边框的颜色
    CDC *pDC = pWnd->GetWindowDC();
    CRect rcWnd;
    pWnd->GetWindowRect(rcWnd);
    pWnd->ScreenToClient(rcWnd);
    int nWidht = rcWnd.Width();
    int nHeight = rcWnd.Height();
    rcWnd.left = 1;
    rcWnd.top = 1;
    rcWnd.bottom = rcWnd.top+nHeight-1;
    rcWnd.right = rcWnd.left + nWidht-1;
    CPen pen(PS_SOLID, 1, RGB(255, 0, 128));
    HPEN Oldpen = (HPEN)pDC->SelectObject(pen);
    pDC->Rectangle(rcWnd);
    pDC->SelectObject(Oldpen);
    pWnd->ReleaseDC(pDC);
  }

Answer 6

在这里修改指针位置么?
//修改窗体边框的颜色
CDC *pDC = pWnd->GetWindowDC();

Answer 7

修改文本框边界颜色，该用WM_DRAWITEM事件，还是OnCtlColor事件呢？

Answer 8

用下面的代码，运行时有错误//修改文本框背景颜色
HBRUSH CSkinTestDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
     HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

    //修改编辑框
    if (pWnd->GetDlgCtrlID() == IDC_EDIT1)
    {
        pDC->SetTextColor(RGB(0,0,0)); //编辑框类的字体设置为黑色；
        pDC->SetBkMode(TRANSPARENT);   //设置为透明不影响字体颜色 //修改Edit文本框的边框颜色
//CDC *pDC = pWnd->GetWindowDC();
CRect rcWnd;
pWnd->GetWindowRect(rcWnd);
pWnd->ScreenToClient(rcWnd);
int nWidht = rcWnd.Width();
int nHeight = rcWnd.Height();
rcWnd.left = 1;
rcWnd.top = 1;
rcWnd.bottom = rcWnd.top+nHeight-1;
rcWnd.right = rcWnd.left + nWidht-1;
CPen pen(PS_SOLID, 1, RGB(0, 255, 128));
HPEN Oldpen = (HPEN)pDC->SelectObject(pen);
pDC->Rectangle(rcWnd);
pDC->SelectObject(Oldpen);
        pWnd->ReleaseDC(pDC); 

        return (HBRUSH)m_MeaningBrush.GetSafeHandle();
    }

void CNewEdit::OnNcPaint()  
{
// TODO: Add your message handler code here// Do not call CEdit::OnNcPaint() for painting messages
CDC *pDC = GetWindowDC();CRect rcWnd;
GetWindowRect(rcWnd);
ScreenToClient(rcWnd);
int nWidht = rcWnd.Width();
int nHeight = rcWnd.Height();
rcWnd.left = 1;
rcWnd.top = 1;
rcWnd.bottom = rcWnd.top+nHeight-1;
rcWnd.right = rcWnd.left + nWidht-1;
CPen pen(PS_SOLID, 1, RGB(255, 0, 128));
HPEN Oldpen = (HPEN)pDC->SelectObject(pen);pDC->Rectangle(rcWnd);pDC->SelectObject(Oldpen);
ReleaseDC(pDC);
}

12楼的版主能不能把OnNcPaint在说一说。有改变list control控件边框颜色的方法吗，希望大家帮一下
