WM_CTLCOLOR消息的用法。有关控件…

出自http://blog.chinaunix.net/uid-24585655-id-2125549.html





HBRUSH CDialogColor::OnCtlColor(CDC*pDC, CWnd* pWnd,UINT nCtlColor)
{
    HBRUSHhbr = CDialog::OnCtlColor(pDC,pWnd,nCtlColor);
    //TODO: Change any attributes of theDC here

    //设置显示字体
   pDC->SetBkColor(RGB(255,255,255));//改变所有控件字体的背景色
    CFont* cFont=newCFont;
    cFont->CreateFont(16,0,0,0,FW_SEMIBOLD,FALSE,FALSE,0,
                                          ANSI_CHARSET,OUT_DEFAULT_PRECIS,
                                          CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,
                                          DEFAULT_PITCH&FF_SWISS,"Arial");
    //对特定的控件做修改

    switch()
    {
       caseCTLCOLOR_STATIC: //对所有静态文本控件的设置

      {
          pDC->SetBkMode(TRANSPARENT);
          //设置背景为透明

          pDC->SetTextColor(RGB(255,255,0));//设置字体颜色

          pWnd->SetFont(cFont);//设置字体

          HBRUSHB =CreateSolidBrush(RGB(125,125,255));
          //创建画刷

          return(HBRUSH) B;//返回画刷句柄

      }
      caseCTLCOLOR_EDIT: //对所有编辑框的设置

     {
          pDC->SetBkMode(TRANSPARENT);
          pDC->SetTextColor(RGB(255,255,0));
          pWnd->SetFont(cFont);
          HBRUSHB =CreateSolidBrush(RGB(125,125,255));
          return(HBRUSH) B;
      }
      default:
      returnCDialog::OnCtlColor(pDC,pWnd,nCtlColor);
    }
}

注：case的类别有以下几种：
CTLCOLOR_BTN 按钮控件
CTLCOLOR_DLG 对话框
CTLCOLOR_EDIT 编辑框
CTLCOLOR_LISTBOX 列表框
CTLCOLOR_MSGBOX 消息框
CTLCOLOR_SCROLLBAR 滚动条
CTLCOLOR_STATIC 静态文本
2.你可能觉得对所有的控件使用统一的界面设置觉得不自由，其实VC同样可以对特定的ID的控件进行设置，方法如下：

switch(pWnd->GetDlgCtrlID())
{
  //针对ID为IDC_CTL1、IDC_CTL2和IDC_CTL3的控件进行同样的设置

     case IDC_CTL1:
     case IDC_CTL2:
     case IDC_CTL3:
     {
            pDC->SetBkMode(TRANSPARENT);
            pDC->SetTextColor(RGB(255,255,0));
            pWnd->SetFont(cFont);
            HBRUSHB =CreateSolidBrush(RGB(125,125,255));
            return(HBRUSH) B;
     }
     default:
            returnCDialog::OnCtlColor(pDC,pWnd, nCtlColor);
}
