[펌] [java] for 문으로 Map loop돌때 쓰면 좋은 방법.

출처 : http://lotus.tistory.com/78

Map 같은 자료구조로 이터레이션 할때 여러가지 방법을 쓸 수 있는데 검색하다가 깔끔한 코드를 발견해서 첨부해 본다. ㅋ
난 자바 뉴비..ㅎㅎ

- 그저 그런 방법

Set<Integer> set = map.keySet();

for(Integer key : set)

{

System.out.println(key + " " + map.get(key));

}

- 좀 더 깔끔한 방법

for (Map.Entry<Integer, String> entry : map.entrySet() )

{

System.out.println(entry.getKey() + " " + entry.getValue());

}

[펌] FLEX에 움직이는 GIF 넣기

첨부한 파일을 다운 받아서 프로젝트에 넣어주시구요.

(출처 : http://flexology.wordpress.com/2008/09/30/loadinganimated_gif_in_flex/ )

AnimatedGIFImage.as 파일을 추가합니다.
소스는 아래와 같습니다.

package gif
{
import flash.net.URLRequest;

import mx.controls.Image;
import mx.core.UIComponent;

import org.gif.player.GIFPlayer;

public class AnimatedGIFImage extends Image
{
private var _gifImage:UIComponent;

  public function AnimatedGIFImage()
  {
   super();
   this._gifImage=new UIComponent();
  }

  override public function set source(value:Object):void
  {
   if (!value is String)
   {
    throw new ArgumentError("Source must be of type String");
   }

super.source=value;
}

  override protected function createChildren():void
  {
   super.createChildren();
   var player:GIFPlayer=new GIFPlayer();
   player.load(new URLRequest(this.source as String));
   this._gifImage.addChild(player);
  }

  override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
  {
   this.addChild(this._gifImage);
   super.updateDisplayList(unscaledWidth, unscaledHeight);
  }
}
}

그리고 사용하실땐
<gif:AnimatedGIFImage source="test.gif" width="100" height="100"/> 와 같이 사용하시면 됩니다.

flex Tree Icon Spinner (not using animated gif)

Tree Icon Spinner (not using animated gif)

I've been disappointed that Flex doesn't natively support animated gifs. I especially wanted to use them inside Flex Trees when I'm loading the children dynamically. So instead of trying to get animated gifs to work (see this example if you are interested) I created a relatively simple Spinner class that draws a circular spinner using just Flex Graphics. The spinner is animated using a Timer. If you set the startImmediately property to true then the animation starts when the spinner component is added to a parent component. And it is always stopped when it gets removed from its parent.
There are also the start(), stop() and running functions to control the spinner manually.

The spinners have a few styles that you can set to customize the appearance:

<ui:Spinner
  Properties
delay="100"
startImmediately="false"
Styles
backgroundAlpha="1"
backgroundColor="NaN"
spinnerColor="#829AD1"
spinnerHighlightColor="#001A8E"
spinnerThickness="3"
spinnerLineThickness="2"
spinnerType="gradientcircle"/>

I've created an example of the four types of spinners in four Trees. Each tree node loads its children after a 2 second delay during which time the spinner is shown, so try expanding each tree (right click to view source):

Let me know if you like them!

Also, make sure you do call stop() on the spinner when you don't need it anymore... otherwise you might notice your Flex app starts to run very slowly like mine did...

[펌] Progressbar in Datagrid Example

Progressbar in Datagrid Example

출처 : http://www.flex-blog.com/progressbar-in-datagrid-example/

Line Break

Author: Roelof (13 Articles) - Author Website

Roelof is a SAP Consultant specialized in Front-End development. In his spare free time he is either developing on the web, playing basketball, watching soccer or traveling. He is also the co-owner of Flex-Blog.com.

In the comments of our previous post about using the ProgressBar, one of our readers asked if a ProgressBar could be used inside a DataGrid.

This is, ofcourse, possible. So we decided to write an example about this.

There are a couple of things you need to know before we start:

Use an ItemRenderer to show the ProgressBar inside the DataGrid instead of text.
Create a DataProvider for the DataGrid (in our case we use an ArrayCollection).
Create an action to start the ProgressBar (in our case we simulate a download).
Make sure the ArrayCollection is updated on every progress of the ProgressBar.

First we create an ItemRenderer in a seperate ActionScript file (myProgressBar.as):

1

3
4
5

9

package
{
import mx.containers.HBox;
import mx.controls.ProgressBar;
import mx.controls.dataGridClasses.*;

public class myProgressBar extends HBox
//This should normally be extends ProgressBar, we are using HBox to have more control over the layout.
{
private var pb:ProgressBar;

public function myProgressBar():void {
//Create new ProgressBar Instance
pb = new ProgressBar();
//Set some layout things
pb.mode = "manual";
pb.percentWidth = 100;
pb.labelPlacement = "center";
this.setStyle("verticalAlign","middle");
//Add ProgressBar as child
addChild(pb);
}

override public function set data(value:Object):void
{
super.data = value;
}

override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number) : void{
super.updateDisplayList(unscaledWidth, unscaledHeight);
pb.setProgress(data.loaded, data.total);
}
}
}

Then we will use this ItemRenderer inside the DataGrid column.

1	<mx:DataGridColumn itemRenderer="myProgressBar" dataField="progress" headerText="Progress" width="180" paddingLeft="5"/>

To start the ‘fake’ ProgressBar download progress, we are using an Image as a Button inside the DataGrid.

1
2
3
4
5
6
7
8
9
10

<mx:DataGridColumn width="112" headerText="Download">
<mx:itemRenderer>
<fx:Component>
<mx:HBox horizontalAlign="center" verticalAlign="middle">
<s:Label text="{data.file}"/>
<mx:Image buttonMode="true" toolTip="'Download'" click="outerDocument.downloadFile()" source="@Embed(source='images/down_alt.png')"/>
</mx:HBox>
</fx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>

Why use outerDocument?
Since the itemRenderer is within another Component, we need to use outerDocument to call a method inside your ‘main’ Component.

Next step was to implement the method downloadFile():

1
2
3
4
5
6
7

public function downloadFile():void{
//start timer
var timer:Timer = new Timer(500);
// add event listener
timer.addEventListener(TimerEvent.TIMER, updateProgressBar);
timer.start();
}

Next, implement the eventListener. Inside the eventListener we need to make sure the DataGrid / ArrayCollection gets updated.

1
2
3
4
5
6
7

private function updateProgressBar(event:TimerEvent):void{
var myItem:Object;
// Add a 'random' number to loaded. To fake the progress..
myDataGrid.selectedItem.loaded += Math.ceil(Math.random() * 5);
//refesh arraycollection to refresh the datagrid
myArrayCollection.refresh();
}

Then you are done. Below you will find a working example. For the full source code either use Right Mouse Click -> View Source or scroll down.

Copy Flex UIComponent

Posted on November 14, 2010 by sukantadas

I was trying to copy a canvas(UIComponent), but realize that it’s not a simple job as it looks like.

1. One can use the ObjectUtil.copy()..method to copy a simple object, but we can not use the same for UIComponent.

2. Secondly, one can use Bitmap to copy the Image type. Like…

public static function cloneImage(image:Image):Image
          {
               var clone:BitmapData = Bitmap(image.source).bitmapData.clone();
               var bitmap:Bitmap           = new Bitmap(clone);

               var newImage:Image          = new Image();
               newImage.source           = bitmap;

               return newImage;
          }
3.Thirdly, we can use the componentDescriptor to create a container

Like..

<?xml version=”1.0″ encoding=”utf-8″?>
<mx:Application xmlns:mx=”http://www.adobe.com/2006/mxml” layout=”horizontal”>
     <mx:Script>
          <![CDATA[
               private function cloneButton_clickHandler (event:MouseEvent):void
               {
                    var childDescriptors:Array = original.childDescriptors;
                    var descriptorsCount:int = childDescriptors.length;
                    for (var i:int; i < descriptorsCount; i++)
                    {
                         cloned.createComponentFromDescriptor(original.childDescriptors[i],
                                                                       false);
                    }
                    cloned.validateNow();
               }
          ]]>
     </mx:Script>
     <mx:Button label=”Clone Canvas” click=”cloneButton_clickHandler(event);” />
     <mx:Canvas id=”original” width=”100″ height=”100″ borderStyle=”solid” >
          <mx:Label text=”Some Label” />
          <mx:ComboBox dataProvider=”{['data1', 'data2']}” bottom=”0″ />
     </mx:Canvas>
     <mx:Canvas id=”cloned” width=”100″ height=”100″ borderStyle=”solid” >

     </mx:Canvas>
</mx:Application>

but, still there is a problem in the above method. It copy only the first level children.

For more usefulness we need to make RECURSIVE call to this method to copy each and every children it has which is really frustating…:(

4. I also tried to implement this by using Reflection API or taking a snapshot of the current view…

But, unfortunately flex does not have snapshot method. I guess we need to take help of ExternalInterface to implement the sanpshot method..

After going through all this I find that flex should have make this more simplify by providing an interface to clone any UICompoent.

Sorry to say, I guess flex is really lagging in this regard…

flex Printing

Printing

Adobe® Flash® Player and Adobe® AIR™ can communicate with an operating system’s printing interface so that you can pass pages to the print spooler. Each page Flash Player or AIR sends to the spooler can contain content that is visible, dynamic, or offscreen to the user, including database values and dynamic text. Additionally, Flash Player and AIR set the properties of the flash.printing.PrintJob class based on a user’s printer settings, so that you can format pages appropriately.

This chapter details strategies for using the flash.printing.PrintJob class methods and properties to create a print job, read a user’s print settings, and make adjustments to a print job based on feedback from Flash Player or AIR and the user’s operating system.
