【MFC开发（11）】静态文本框控件 StaticText

静态文本框控件 StaticText与分组控件类似，也没有什么响应函数，直接显示内容；

下面讲解一下如何去使用别人的模板来调用

添加文件到项目中，这里只需要2个文件

这里放一下代码吧

Let's use our own code to display gradient background.//This code is very simple and produces worse gradient that function from the library - but works!DrawGradRect(&dc,rect,clLeft,clRight,m_bVertical);}//let's set color defined by user::SetTextColor(dc,clText);HFONT hfontOld;CFont* pFont = GetFont();CString m_sTEXT;GetWindowText(m_sTEXT);if(pFont)hfontOld = (HFONT)SelectObject(dc.m_hDC, (HFONT)pFont->m_hObject);::SetBkMode(dc, TRANSPARENT);GetClientRect(&rect);if(m_iAlign == 1) // center::DrawText(dc, m_sTEXT, -1, &rect, DT_SINGLELINE|DT_VCENTER|DT_CENTER);else if(m_iAlign == 0) // left{rect.left+=m_iLeftSpacing;::DrawText(dc, m_sTEXT, -1, &rect, DT_SINGLELINE|DT_VCENTER|DT_LEFT);}else //right{rect.right-=m_iLeftSpacing;::DrawText(dc, m_sTEXT, -1, &rect, DT_SINGLELINE|DT_VCENTER|DT_RIGHT);}if(pFont)::SelectObject(dc.m_hDC, hfontOld);
}void CGradientStatic::SetReverseGradient()
{COLORREF cTemp = clLeft;clLeft = clRight;clRight = cTemp;
}void CGradientStatic::SetWindowText(LPCSTR a_lpstr)
{//CStatic::SetWindowText(a_lpstr);Invalidate();
}

然后新建一个static text控件，为其添加变量

	//使用模板中的类CGradientStatic m_static_text;

效果如下
