VC中创建不规则窗体

鼯鼠

创建不规则窗体的几个主要函数：<br>&lt;1&gt;&nbsp;CreateRectRgn&nbsp;:&nbsp;创建矩形窗体轮廓。<br>&lt;2&gt;&nbsp;CreateRoundRectRgn&nbsp;:&nbsp;创建圆角矩形窗体轮廓。<br>&lt;3&gt;&nbsp;CreateEllipticRgn&nbsp;:&nbsp;创建圆形或椭圆形窗体轮廓。<br>&lt;4&gt;&nbsp;CreatePolygonRgn&nbsp;:&nbsp;创建多边形窗体轮廓。<br><br>上面函数在创建不规则窗体轮廓时可直接使用，无须自己指定轮廓路径。如果想让窗体更复杂，你可以使用CombineRgn把多个轮廓路径混合起来实现。上面的函数还可以用BeginPath，EndPath和PathToRegion三个函数实现，用户可以自定义窗体轮廓路径。<br><br>在头文件中加入：<br>HRGN&nbsp;m_wndRgn;<br><br>然后在OnInitDialog函数中加入：<br><br>CDC*&nbsp;pDC&nbsp;=&nbsp;GetDC();<br>CFont&nbsp;mFont;&nbsp;&nbsp;&nbsp;&nbsp;<br>//创建字体<br>VERIFY(mFont.CreateFont(<br>&nbsp;&nbsp;&nbsp;&nbsp;200,&nbsp;//&nbsp;height&nbsp;of&nbsp;font<br>&nbsp;&nbsp;&nbsp;&nbsp;50,&nbsp;//&nbsp;average&nbsp;character&nbsp;width<br>&nbsp;&nbsp;&nbsp;&nbsp;0,&nbsp;//&nbsp;angle&nbsp;of&nbsp;escapement<br>&nbsp;&nbsp;&nbsp;&nbsp;0,&nbsp;//&nbsp;base-line&nbsp;orientation&nbsp;angle<br>&nbsp;&nbsp;&nbsp;&nbsp;FW_HEAVY,&nbsp;//&nbsp;font&nbsp;weight<br>&nbsp;&nbsp;&nbsp;&nbsp;TRUE,&nbsp;//&nbsp;italic&nbsp;attribute&nbsp;option<br>&nbsp;&nbsp;&nbsp;&nbsp;FALSE,&nbsp;//&nbsp;underline&nbsp;attribute&nbsp;option<br>&nbsp;&nbsp;&nbsp;&nbsp;0,&nbsp;//&nbsp;strikeout&nbsp;attribute&nbsp;option<br>&nbsp;&nbsp;&nbsp;&nbsp;ANSI_CHARSET,&nbsp;//&nbsp;character&nbsp;set&nbsp;identifier<br>&nbsp;&nbsp;&nbsp;&nbsp;OUT_DEFAULT_PRECIS,&nbsp;//&nbsp;output&nbsp;precision<br>&nbsp;&nbsp;&nbsp;&nbsp;CLIP_DEFAULT_PRECIS,&nbsp;//&nbsp;clipping&nbsp;precision<br>&nbsp;&nbsp;&nbsp;&nbsp;DEFAULT_QUALITY,&nbsp;//&nbsp;output&nbsp;quality<br>&nbsp;&nbsp;&nbsp;&nbsp;DEFAULT_PITCH&nbsp;|&nbsp;FF_SWISS,&nbsp;//&nbsp;pitch&nbsp;and&nbsp;family<br>&nbsp;&nbsp;&nbsp;&nbsp;"宋体"&nbsp;//&nbsp;typeface&nbsp;name<br>&nbsp;&nbsp;&nbsp;&nbsp;javascript :if(this.width&gt;screen.width/2)this.width=screen.width/2" vspace=2 border=0&gt;);<br>//开始记录窗体轮廓路径<br>pDC-&gt;BeginPath();&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>//设置背景为透明模式。<br>pDC-&gt;SetBkMode(TRANSPARENT);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br>CFont&nbsp;*&nbsp;pOldFont;<br>pOldFont&nbsp;=&nbsp;pDC-&gt;SelectObject(&nbsp;&amp;mFont&nbsp;javascript :if(this.width&gt;screen.width/2)this.width=screen.width/2" vspace=2 border=0&gt;;<br>pDC-&gt;TextOut(0,&nbsp;0,&nbsp;"吴雨"javascript :if(this.width&gt;screen.width/2)this.width=screen.width/2" vspace=2 border=0&gt;;&nbsp;&nbsp;&nbsp;&nbsp;<br>pDC-&gt;SelectObject(&nbsp;pOldFont&nbsp;javascript :if(this.width&gt;screen.width/2)this.width=screen.width/2" vspace=2 border=0&gt;;<br>mFont.DeleteObject();<br>//结束记录窗体轮廓路径<br>pDC-&gt;EndPath();<br>//把所记录的路径转化为窗体轮廓句柄<br>m_wndRgn&nbsp;=&nbsp;:athToRegion(pDC-&gt;m_hDC);<br>//赋予窗体指定的轮廓形状<br>SetWindowRgn(m_wndRgn,&nbsp;TRUE);
