<h2><font color="#009999">演示设置各种样式的打印预览窗口：</font>
</h2>
<p>预览窗口可以通过如下函数进行设置，以便适应不同的预览需要：</p>  
<p><font color="#0000FF">SET_PREVIEW_WINDOW(intDispMode,intToolMode,blDirectPrint,intWidth,intHeight,strTitleButtonCaptoin)</font></p>  
<p>参数含义:</p>  
<p><font color="#0000FF">intDispMode</font><font color="#0000FF">：</font>预览比例，数字型，0-适高&nbsp;                 
1-正常大小&nbsp; 2-适宽</p>                   
<p><font color="#0000FF">intToolMode：</font><span>工具条和按钮，数字型</span><span>&nbsp;                 
0-</span><span>显示(上方)工具栏</span><span lang="EN-US" style="color:black">&nbsp;&nbsp;                 
1-</span><span>显示(下方)按钮栏</span><span lang="EN-US" style="color:black">&nbsp;&nbsp;&nbsp;                 
2-</span><span>两个都显示</span><span lang="EN-US" style="color:black">&nbsp;&nbsp;                 
3-</span><span>两个都不显示</span><span lang="EN-US" style="color:black"> <o:p>
</o:p>
</span></p>   
<p><font color="#0000FF">blDirectPrint</font><font color="#0000FF">：</font>
<span>打印按钮是否“直接打印”                      
1-是&nbsp; 0-否（弹出界面“选机打印”）</span></p>                      
<p><font color="#0000FF">intWidth,intHeight </font>窗口的宽和高，整数型，单位是<span>px</span></p>                      
<p><font color="#0000FF">strTitleButtonCaptoin </font><span>预览窗口和打印按钮的名称组合，字符型，用“点”分隔</span></p>  
<p><span>演示如下<b>：</b></span></p>  
<p>A、以普通方式<a href="javascript:myPreview1()">打印预览1</a>（窗口满屏）,自定窗口大小的<a href="javascript:myPreview2()">打印预览2</a>
<p>B、无工具条和按钮的小窗口纯<a href="javascript:myPreview3()">预览3</a><p>C、带“开始打印”和“关闭”按钮的<a href="javascript:myPreview4()">预览4</a>，窗口始终在最前面，不能最小化。 
<p>D、为形象显示打印方向与走纸方向的关系，<a href="javascript:myPreview1()">打印预览1</a>底图上有模拟走纸板的条纹线，可以隐藏该条线，见
<a href="javascript:myPreview5()">打印预览5</a>。
<p>E、一般横向<a href="javascript:myPreview6()">打印预览6</a>的内容是旋转90度以准确描述横向的含义，可以设置成正向显示以符合传统习惯，见<a href="javascript:myPreview7()">打印预览7</a>。
<br><i>(注意传统习惯是错误的,尽管看上去“顺眼”，但很容易让操作者误以为横向打印要旋转纸张)</i>
<p>F、带“打印”和“关闭”按钮的<a href="javascript:myPreview8()">打印预览8</a>，其中打印按钮会弹出选机窗口,程序控制打印后自动关闭窗口。
<p>G、要显示预览窗口的标尺参考<a href="javascript:myPreview9()">打印预览9</a>(看不到时请在预览界面右键菜单里选"显示标尺")<p><a href="PrintSampIndex.html">&lt;&lt;回样例目录</a>
