MFC设置字体及颜色.doc

MFC设置字体及颜色设置字体函数原型: BOOL CreateFont( int nHeight, int nWidth, int nEscapement, int nOrientation, int nWeight, BYTE bItalic, BYTE bUnderline, BYTE cStrikeOut, BYTE nCharSet, BYTE nOutPrecision, BYTE nClipPrecision, BYTE nQuality, BYTE nPitchAndFamily, LPCTSTR lpszFacename ); 参数说明: nHeight :字体高度. 三中情况 1、0:字体的高度值（设备坐标）;2、=0:字体采用缺省值. 3、CreateFont(-11,0,0,0,100,FALSE,FALSE,0,ANSI_CHARSET,OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,FF_SWISS,Arial); CEdit *m_Edit=(CEdit *)GetDlgItem(IDC_EDIT1); m_Edit-SetFont(m_Font,FALSE); return TRUE; / return TRUE unless you set the focus to a control 小小说明:在OnInitDialog()中的/CFont m_Font;前的/号去掉,将类声明中的CFont m_Font;去掉会是什么结果?请自己试试.改变Edit字体颜色！HBRUSH CButtonDlg:OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) HBRUSH hbr = CDialog:OnCtlColor(pDC, pWnd, nCtlColor); / TODO: Change any attributes of the DC here if(nCtlColor = CTLCOLOR_EDIT) if(pWnd-GetDlgCtrlID()= IDC_EDIT1) pDC-SetTextColor(RGB(255,255,0); pDC-SetBkColor(RGB(251, 247, 200); pDC-SetBkMode(TRANSPARENT); return (HBRUSH) m_brush.GetSafeHandle(); / TODO: Return a different brush if the default is not desired return hbr;CBrush m_brushedit; m_brushedit.CreateSolidBrush (RGB ( 255, 255, 0 ) ); 在Dlg:OnCtlColor函数中加入： if(nCtlColor = CTLCOLOR_EDIT) pDC-SetTextColor(RGB(255,0,0); /文字颜色 pDC-SetBkColor(RGB(255,255,200); /文字背景颜色 return (HBRUSH)m_brushedit.GetSafeHandle() ; /edit框的颜色 改变对话框背景CBitmap m_BkGndBmp;m_BkGndBmp.LoadBitmap(IDB_BITMAP1);BOOL CButtonDlg:OnEraseBkgnd(CDC* pDC)CRect rcClient;GetClientRect(&rcClient);BITMAP bm;m_BkGndBmp.GetBitmap(&bm);CDC memDC;memDC.CreateCompatibleDC(pDC);CBitmap *pOldBmp = memDC.SelectObject(&m_BkGndBmp);pDC-StretchBlt(0,0,rcClient.Width(),rcClient.Height(),&memDC,0,0,bm.bmWidth,bm.bmHeight,SRCCOPY);memDC.SelectObject(pOldBmp);memDC.DeleteDC();return TRUE;/ return CDialog:OnEraseBkgnd(pDC);在一个mfc应用程序中，要改变控件的背景色可通过重载onctlcolor()函数来实现。方法是在该函数中设置所需颜色后再返回一个画刷句柄便可重绘控件背景色。onctlcolor()函数对于控件背景色的处理是通过捕捉相应的控件消息来实现的。常用的此类消息有：ctlcolor_dlg 对话框ctlcolor_edit 编辑框ctlcolor_listbox 列表框ctlcolor_msgbox 消息框ctlcolor_scrollbar 滑动条ctlcolor_static 静态文本框、矩形等。以下示例代码说明如何更改以上控件的背景色：afx_msg hbrush onctlcolor(cdc* pdc, cwnd* pwnd, uint nctlcolor); /重载方法原形声明 *.hafx_msg BOOL OnEraseBkgnd(CDC* pDC);/对话框
