//TITLE:
// CText更新至V1.1.0
//AUTHOR:
// norains
//DATE:
// Saturday 28-April-2007
//Environment:
// EVC4.0 + Standard SDK 4.2
// EVC4.0 + Standard SDK 5.0
//========================================================================
版本历史:
v1.0: http://blog.csdn.net/norains/archive/2007/04/17/1568429.aspx
接口和上一版本的差异:
*SetTextHeight()更名为SetPointSize()
修正的bug:
*创建字体时没有lfCharSet变量,在wince5.0中会导致文字无法对准.
增加的函数:
*SetStrikeOut(BOOL bStrikeOut) //文件中划线
*SetUnderline(BOOL bUnderline) //下划线
*SetItalic(BOOL bItalic) //斜体
*SetWeight(int iWeight) //粗细
*重载 "="操作符,下列代码功能能够正常运作:
CText a, b;
a.SetText(TEXT("TEXT"));
a.SetTextColor(RGB(0,0,255));
b = a;
基本的操作可参照版本v1.0的文章
