flexpaper 的二次开发总结及探讨

1、如创建 ceshi Flex项目  ，把下面代码覆盖项目ceshi.mxml文件

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
				xmlns:fp="com.devaldi.controls.flexpaper.*"

				applicationComplete="initApp();">

2、去打印按钮

     我们找到FlexPaperViewer.mxml文件中的下面部分内容：

    

<mx:HBox styleName="toolbarBackground" width="100%" height="26" borderStyle="solid"
verticalScrollPolicy="off" horizontalScrollPolicy="off" paddingTop="2"
paddingLeft="2" horizontalGap="3">
<st:GradientImageButton icon="{MenuIcons.PRINT_ICON}" styleName="toolbttn"
width="20" click="printPaper(event)" toolTip="@Resource(key='Print',
bundle='FlexPaper')" visible="{!ReadOnly}" includeInLayout="{!ReadOnly}" />
<mx:Image source="{MenuIcons.BAR}" width="3" height="21" visible="{!ReadOnly}"
includeInLayout="{!ReadOnly}" />

 把上面代码的st:GradientImageButton部分代码注释掉就可以了

<!--
<st:GradientImageButton icon="{MenuIcons.PRINT_ICON}" styleName="toolbttn"
width="20" click="printPaper(event)" toolTip="@Resource(key='Print',
bundle='FlexPaper')" visible="{!ReadOnly}" includeInLayout="{!ReadOnly}" />
<mx:Image source="{MenuIcons.BAR}" width="3" height="21" visible="{!ReadOnly}"
includeInLayout="{!ReadOnly}" />
-->

 

3、去右键注释FlexPaperViewer_Base.mxml

     

contextMenu.customItems.push(cmi_about);

contextMenu.customItems.push(cmi_print);

 

4、去掉FP 关于我们按钮

找FlexPaperViewer.mxml文件会找到下面三行代码

//bttnInfo.visible = false;
//bttnInfo.visible = (new MenuIcons.SMALL_TRANSPARENT().width > 10);
//bttnInfo.visible = (new MenuIcons.SMALL_TRANSPARENT().width > 10);

 

5、右下角logo，FlexPaperViewer.mxml文件

 除去加载页的 LOGO 图标，

将<fp:FlexPaperViewer_Base ...>的属性最后行加入 creationComplete 处理:

<fp:FlexPaperViewer_Base xmlns:mx="http://www.adobe.com/2006/mxml"
addedToStage="bindStageEvents(event)"
xmlns:fp="com.devaldi.controls.flexpaper.*"
xmlns:ct="com.devaldi.controls.*"
xmlns:st="com.devaldi.skinning.*"
creationComplete="initApp()">

然后加入处理 initApp()函数到<mx:Script>中
//---------------------------二次编程加入
public function initApp():void {
paper1.removeElementAt(2);
}

 最 后 将 源 码 中 的 函 数
papersLoadingHandler(event:Event) 最 后 一 行 加
上:paper1.removeElementAt(2);

 

    protected override function onViewModeChanged(event:ViewModeChangedEvent):void{  
                    txtPage.text = formatPageNumber(viewer.currPage);  
                    super.onViewModeChanged(event);  
                    paper1.removeElementAt(2);  
                }  

 6、视图切换logo

源文件:DupImage.as
找到语句:private var _skinImgl:Bitmap = new MenuIcons.LOGO_SMALL();
替换为: private var _skinImgl:Bitmap = new Bitmap();
