Flex 3:打印查询
我创建了一个跨度长达 16 周的日程安排应用程序。我希望能够使用 Flex 打印时间表。我创建了一个列出递增日期的测试应用程序。这些日期显然比我的计算机的宽度还要长。我希望我的打印功能能够打印几页上的整个日期宽度...目前,它只打印屏幕上显示的内容。有办法做到这一点吗?
下面是我创建的应用程序。有一些对自定义函数的调用,但它们与当前的问题无关:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init();">
<mx:Script source="functions/dateFunctions.as" />
<mx:Script>
<![CDATA[
import mx.controls.Alert;
import mx.collections.ArrayCollection;
[Bindable] public var date:Date = new Date;
public var numDays:Number = 50;
[Bindable] public var datesAC:ArrayCollection = new ArrayCollection;
public function init():void
{
var tempDate:String = new String;
for (var i:int = 0; i < numDays; i++)
{
tempDate = dateToNumText(rightDate(date.getMonth(), date.getDate() + i, date.getFullYear()));
datesAC.addItem(tempDate);
}
}
private function printMe() :void
{
var pj:PrintJob = new PrintJob();
pj.start();
// setTimeout(function() :void { finishPrinting(pj);}, 1);
finishPrinting(pj);
}
private function finishPrinting(pj:PrintJob): void {
pj.addPage(this);
pj.send();
}

I have created a scheduling application that spans upwards of 16 weeks. I would like to be able to print the schedule using Flex. I've created a test application that lists incrementing dates. These dates obviously stretch longer than the width of my computer. I would like for my print function to print the entire width of dates across several pages... currently, it prints just what appears on my screen. Is there a way to accomplish this?
Below is the app i've created. There are some calls to custom functions, but they in no way relate to the issue at hand:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init();">
<mx:Script source="functions/dateFunctions.as" />
<mx:Script>

import mx.collections.ArrayCollection;
[Bindable] public var date:Date = new Date;
public var numDays:Number = 50;
[Bindable] public var datesAC:ArrayCollection = new ArrayCollection;
public function init():void
{
var tempDate:String = new String;
for (var i:int = 0; i < numDays; i++)
{
tempDate = dateToNumText(rightDate(date.getMonth(), date.getDate() + i, date.getFullYear()));
datesAC.addItem(tempDate);
}
}
private function printMe() :void
{
var pj:PrintJob = new PrintJob();
pj.start();
// setTimeout(function() :void { finishPrinting(pj);}, 1);
finishPrinting(pj);
}
private function finishPrinting(pj:PrintJob): void {
pj.addPage(this);
pj.send();
}

您必须自己对内容进行分解/分页。您可以将每个此类逻辑上分解的页面发送到 PrintJob.appPage() API,以便它成为打印的纸张。目前,正在发生的情况是内容会被剪辑。
You would have to break up/paginate content on your own. You can send each such logically broken up page to PrintJob.appPage() API so it becomes a printed paper. At present, what is happening would be that content would be getting clipped.
我想你应该使用 PrintJob.addPage() 将您的日期添加到打印作业。
I guess you should use PrintJob.addPage() to add your dates to print job.
