I'm trying to setup a system that will allow the user to view PDF forms within
my Flex app. I have created a WindowedApplication containing a HBox with
contains a HTML control. My problem right now is that the PDF will display, but
the window does not open at a good size for viewing. When I resize the window
to better view the PDF, it appears that the HBOX or HTML control is not
resizing properly. Here is the code I have so far:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml";
layout="absolute" resize="resizeWindow()">
<mx:Script>
<![CDATA[
import flash.events.Event;
import mx.events.DropdownEvent;
public var filepath:String;
public var index:int;
public var pdf:HTMLLoader;
private function ResizeViewer():void{
pdf.height = PDFViewer.height
pdf.width = PDFViewer.width
}
private function resizeWindow():void{
if this.is
hboxHtml.height = this.height;
hboxHtml.width = this.width;
}
// Display a selected item's label field and index for change events.
private function changeEvt(event:Event):void {
filepath = cmbForms.text;
index = cmbForms.selectedIndex
switch (index) {
case 0 :
filepath = "C://PDF Docs//822 Individualized
Treatment Plan 6-29-2009 (Reader).pdf";
case 1 :
filepath = "C://PDF Docs//822 Psychosocial
6-3-2009 (Reader).pdf";
case 2 :
filepath = "C://PDF Docs//822 Utilization
Review Form (Reader).pdf";
}
PDFViewer.removeChildAt(0);
var request:URLRequest = new URLRequest(filepath)
//("http://www.example.com/test.pdf";);
pdf = new HTMLLoader();
pdf.height = PDFViewer.height;
pdf.width = PDFViewer.width;
pdf.load(request);
PDFViewer.addChildAt(pdf, 0);
lblTest.text = filepath;
}
]]>
</mx:Script>
<mx:HBox x="0" y="95" width="100%" height="266" verticalAlign="bottom"
id="hboxHtml" resize="resizeHBox()">
<mx:HTML id="PDFViewer" width="100%" height="90%"

</mx:HBox>
<mx:Form x="0" y="0" width="100%" height="87" id="controlForm">

As you can see this is a very basic form. This is the first project in FLEX so
I'm still learning. My ResizeViewer and ResizeWindow functions don't seem to
work as expected. Thanks for any advice that you can give.
