VC IP地址控件(CIPAddressCtrl )的自绘
清泛原创
先看效果图:
代码:
.h
代码:
.h
#pragma once
class CMyIPCtrl : public CIPAddressCtrl
{
DECLARE_DYNAMIC(CMyIPCtrl)
public:
CMyIPCtrl();
virtual ~CMyIPCtrl();
//设置字体
void SetEditFont(CFont* pFont) { m_pSetFont = pFont; }
protected:
DECLARE_MESSAGE_MAP()
private:
COLORREF m_clrBackground; //背景颜色
COLORREF m_clrFrame; //边框颜色
COLORREF m_clrText; //文字颜色
CBrush m_brushBkg; //背景画刷
CFont* m_pfDefault;
CFont* m_pSetFont;
public:
afx_msg void OnNcPaint();
afx_msg HBRUSH OnCtlColor(CDC* /*pDC*/, CWnd* /*pWnd*/, UINT /*nCtlColor*/);
};
.cpp:
#include "stdafx.h"
#include "MyIPCtrl.h"
#include "../../MemDC.h"
#include "../../CommonFunc.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#endif
IMPLEMENT_DYNAMIC(CMyIPCtrl, CIPAddressCtrl)
CMyIPCtrl::CMyIPCtrl() : m_pSetFont(NULL)
{
m_clrBackground = RGB(255, 255, 255); //背景颜色
m_clrFrame = RGB(228, 228, 228); //边框颜色
m_clrText = RGB(174, 174, 174); //文字颜色
m_brushBkg.CreateSolidBrush(m_clrBackground); //创建背景画刷
m_pfDefault = ::GetFont(_T("微软雅黑"), 12);
}
CMyIPCtrl::~CMyIPCtrl()
{
}
BEGIN_MESSAGE_MAP(CMyIPCtrl, CIPAddressCtrl)
ON_WM_NCPAINT()
//ON_WM_CTLCOLOR_REFLECT()
ON_WM_CTLCOLOR()
END_MESSAGE_MAP()
// CWEEditCtrl 消息处理程序
HBRUSH CMyIPCtrl::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT /*nCtlColor*/)
{
m_brushBkg.DeleteObject();
m_brushBkg.CreateSolidBrush(m_clrBackground);
pDC->SetTextColor(m_clrText); //设置文字颜色
pDC->SetBkColor(m_clrBackground); //设置背景色
return (HBRUSH)m_brushBkg.GetSafeHandle();
}
void CMyIPCtrl::OnNcPaint()
{
CRect rectEdit;
CDC* pDC = GetWindowDC();
//设置编辑框的区域
GetWindowRect(rectEdit);
ScreenToClient(rectEdit);
rectEdit.OffsetRect(CSize(2, 2));
CPen mypen, *oldpen;
//判断是否获得焦点
mypen.CreatePen(PS_SOLID, 1, m_clrFrame);
oldpen = pDC->SelectObject(&mypen);
CPoint point(7, 7);
pDC->RoundRect(rectEdit, point);
pDC->SelectObject(oldpen);
//设置字体
SetFont((m_pSetFont != NULL ? m_pSetFont : m_pfDefault));
ReleaseDC(pDC);
}
和CEdit的自绘很类似,唯一的区别在于这里使用OnCtlColor,CEdit使用CtlColor。
