Wetpaint 1 2 3 My Free Wiki Is Up!

WIKI?
A wiki is a type of website that anyone can easily edit and help grow through collaboration.

WETPAINT?
Is a 100% Free wiki (collaborative) authoring tool (it claims to be! Visit Professional Services and explore.), which enables anyone easily to start a free wiki that they can share with students, colleagues, friends, family, etc.

FEATURES?
Wetpaint is a reasonably easy-to-learn/use wiki tool, which has an amazingly attractive look-and-feel (subject to subjectivity!). Yeah, I can tell you also that this tool has an amazing list of features, and they are adding new features all the time (according to them), so theres always something new to try. Here are some of the juicy features:

1-2-3 Simple Site Creation
Public or Private Sites
Pre-Populated Templates (Classrooms, Group Projects, Gaming Clans, etc)
Easy Photo/Video Integration
Page Level Discussion Threads
Customizable Page Templates
Spell Check
Menu of Popular Widgets
Private Onsite Messaging
Address Book Upload
Site Statistics (Google Analytics and SiteMeter)
RSS updates
Email Notifications
Etc.

Except for the annoying Google Ads (which is probably the main source of income for Wetpaint), floating toolbars, and the clipboard bug (minor fix needed!), this tool I believe is going to be a global Wiki smash hit soon. Dont ask me why! Just try it out for yourself :)

Today well add some "Add files" button functionality.

Go to the first NavigatorContent container and ste the first labels id to labelSelected. Set the TileLists widht to 282, columnWidth and columnHeight to 60, columnCount to 4 and itemRenderer to a custom class called TileRenderer.

Set the "Add files" buttons click event handler to addFiles() function:

<s:NavigatorContent width="100%" height="100%" hideEffect="fadeOut" showEffect="fadeIn">
<s:VGroup width="100%" height="100%" paddingLeft="10" paddingTop="10" paddingRight="10" paddingBottom="10">
<s:Label id="labelSelected">0 files selected</s:Label>
<mx:TileList id="tileList" width="282" height="100%" dataProvider="{selectedFiles}" itemRenderer="TileRenderer" columnWidth="60" rowHeight="60" columnCount="4" />
<s:Button label="Add folder" width="100%" />
<s:Button label="Add files" width="100%" click="addFiles();" />
<s:Button label="Continue" width="100%" click="contentStack.selectedIndex = 1;" />
</s:VGroup>
</s:NavigatorContent>

In the script tags declare a new ArrayCollection called slectedFiles, make it bindable:

[Bindable]
private var selectedFiles:ArrayCollection = new ArrayCollection([]);

Now create this addFiles() function and inside of it create a new File object. Call its browseForOpenMultiple() method and add a filter for jpg, jpeg and png pictures. Add a SELECT_MULTIPLE event listener for the File.

private function addFiles():void {
var file:File = new File();
file.browseForOpenMultiple("Select JPG or PNG files", [new FileFilter("Pictures", "*.jpg;*.jpeg;*.png")]);
file.addEventListener(FileListEvent.SELECT_MULTIPLE, filesSelected);
}

The fileSelected function, which is a handler to the SELECT_MULTIPLE event, loops through the receives files and adds their native paths to the selectedFiles array. However, we must keep in mind that the user might accidently import the same file twice, so we need to check if the file already exists in the array before adding it. We use another loop for that. After the loop, we set labelSelecteds text to display how many files are selected:

private function filesSelected(evt:FileListEvent):void {
for (var i:int = 0; i < evt.files.length; i++) {
var alreadySelected:Boolean = false;
for (var u:int = 0; u < selectedFiles.length; u++) {
if (selectedFiles[u] == evt.files[i].nativePath) {
alreadySelected = true;
}
}
if (!alreadySelected) selectedFiles.addItem(evt.files[i].nativePath);
}
labelSelected.text = selectedFiles.length + " files selected";
}

Now create a new mxml file called TileRenderer.mxml. This is our custom item renderer for the TileList. Set the root tags to a VBox, and inside of it create an Image object with source bound to {data}, which is the received image url. Set maxWidth to 60, maxHeight to 60 and scaleContent to true:

<?xml version="1.0" encoding="utf-8"?>
<mx:VBox xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
horizontalAlign="center"
verticalAlign="middle" horizontalScrollPolicy="off"
verticalScrollPolicy="off">
<mx:Image source="{data}" maxWidth="60" maxHeight="60" scaleContent="true"/>
</mx:VBox>

And full Main.mxml code looks like this:

<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"

ActionScript 3 Number to String Conversion

In this lesson, were going to learn how to convert numbers to strings in AS3.

If you youd like to do ActionScript 3 Number to String conversions, then you can use the toString() method of the Number class.

Here is an example:

var myNumber:Number = 7;
var myString:String = myNumber.toString();

Here, we start off by creating a number - myNumber with a value of 7. In the next line, that number is converted into a string and is assigned to a variable named myString.

Why would I want to convert numbers to strings?
One example of how this can be useful is if youd like to calculate some number value and then display it inside a text field.

For example:

var value1:Number = 7;
var value2:Number = 2;
var total:Number = value1 + value2;

myTextField.text =  total.toString();
// Assume that myTextField is an instance of the TextField class
// and that it has already been created and added to the stage

Here, were creating two numbers (7 and 2), which are then added together (which sums up to 9). The sum is then displayed inside a text field. Without the toString() method, Flash will give us an error message if we try to assign a Number value inside the text field. The error message will state:

1067: Implicit coercion of a value of type Number to an unrelated type String.

This means that we are trying to force a number to be a string. A text field can not contain Number data so we will have to convert it to a String instead. Although, 9 as a Number looks the same as "9" as a String, you must still explicitly differentiate between the two inside your ActionScript 3 code. This makes AS3 number to string conversions pretty useful.

If the number is a decimal (e.g. .5), Flash will add a leading 0 when it performs the number to string conversion (i.e. .5 will become "0.5").

Also, the toString() method of the Number class accepts one parameter for the radix. The radix lets you specify which numeric base (from 2 to 36) to use when the number is converted into a string. For example, if youd like the number to be interpreted as an octal (base 8), then you pass a value of 8 to the radix parameter:

var myNumber:Number = 14;
trace( myNumber.toString(8) );

If we used base 10, then this will still output 14. But since we specified base 8 instead, this will output 16. If no radix is specified, a default value of 10 (decimal) is used.

So that is how you do ActionScript 3 number to string conversions.
