[flexcoders] Barcode component for Flex2
Hi!
I got the Barcode component from Antonio I. Aguilar J. and ported it to
Flex2.
The component is able to draw type 128C barcodes.
I add three files here, for Barcode generation (Barcode.as -- the
drawing component itself, BarcodeGenerator.as -- the generator component
which invokes Barcode.as with some parameters, BarcodeExample.mxml --
just a example application, which shows, how to create Barcodes).
Barcode.as
package {
/**
* Barcode.as
* Class to generate barcodes
* At this version, just type 128 barcodes could be generated
*
* @author Antonio I. Aguilar J., Friedrich Dimmel
([EMAIL PROTECTED])
* @version 2007.02.22

Hi. I've managed to store binary objects in the SharedObject. We're transferring the image now Base64Encoded which Flex recognizes as ByteArray! This can be stored in the SharedObject.

[flexcoders] Re: Validator: disable active validator
Hi,
I've got the solution now. I'll post it, if someone needs it in the
future:
In general: I've a ArrayCollection validators where I put all my
validators in (when I create them (dynamically)).
On creation of my FormItems (i.e. a TextInput called editor), I add
the following two EventListeners:
editor.addEventListener(Event.CHANGE, validateForm);
editor.addEventListener(Event.CHANGE, turnOnOneValidator);
Then my ActionScript functions for validation:
/**
* validates all form elements. in allValid all return values from each
validation are boolean combined
* (if a single element returns false, everything is false
*/
internal function validateForm():Boolean {
var result:ValidationResultEvent = null;
var allValid:Boolean = true;
for(var i:Number=0; ivalidators.length; i++) {
result = validators.getItemAt(i).validate();
if(result.results != null) {
allValid = false;
result = null;
}
}
return allValid;
}
/**
* disables all validators
* simulates a ValidationResultEvent with VALID for each control (all
red borders will disappear)
*/
internal function turnOffValidators():void {
for(var i:Number=0; ivalidators.length; i++) {
validators.getItemAt(i).enabled = false;
var evt:ValidationResultEvent = new
ValidationResultEvent(ValidationResultEvent.VALID);
validators.getItemAt(i).source.validationResultHandler(evt);
}
}
/**
* enables all validators
*/
internal function turnOnValidators():void {
for(var i:Number=0; ivalidators.length; i++) {
validators.getItemAt(i).enabled = true;
}
}
/**
* turns on a specific validator (the one from event.target)
* if there's a control changed and the input won't validate, it should
be marked with a red border,
* event if the entire form has disabled validators
*/
internal function turnOnOneValidator(event:Event):void {
for(var i:Number=0; ivalidators.length; i++) {
if(validators.getItemAt(i).source == event.target) {
validators.getItemAt(i).enabled = true;
}
}
}
I hope, this may help someone too :-)
You've to play around, when to enable and disable your validators, but I
think, you'll get this!
Bye,
Fritz

Hi.

Hi! Is it possible to not let a user leave a editable column in a datagrid with a custom textinput with a validator, to focus out (leaving the edit mode).

[flexcoders] Re: Use a Popup as itemEditor in Datagrids
Hi! I was thinking similar to you, but I didn't get it out, how to implement this. How can I react on the itemEditBeginning event within the component. E.g. I've a Canvas as itemEditor. I could open the window on initialize. But: how can I then put some values to the popup? Within the canvas I just have the data object, which only gives me the values of the current row in the datagrid. for the popup this may be enough (more or less) but when the popup is closed, how can I dispatch the itemEditEnd or something like that for the grid, without having further information? Can anyone please show me some lines of code, how to implement this? Thanks, Fritz --- In flexcoders@yahoogroups.com, Michael Labriola [EMAIL PROTECTED] wrote: My first thought: I would probably write a simple component that serves as an itemRenderer. From within that component I would be to launch a modal popup window from the itemEditBeginning event. Ensure that you pass the row and the dataGridColumn (much like a labelFunction) to the new popup. Have it do whatever it is that needs to be done. Then listen for the popup to close and manually handle the update to the collection through the renderer by listening to itemEditEnd. This is just a high level thought. There are some other details, but the concept would probably work with a bit of tweaking. --mike --- In flexcoders@yahoogroups.com, fritzdimmel fritz.dimmel@ wrote: Hi!

[flexcoders] Re: 1st flex 2 project, startup problems
Hey! At first: a big thank you, I'm gonna try to get this work on
monday at my office!
Well: I can't tell you exactly what I want to do, I just wanted to
know how that stuff works. I already knew the creationComplete things.
I wanted to know, how to use the Flash Events.
Finally I have to port a running Flash application to Flex2. Because
it doesn't really work (at least for me), to use the existing swf in
Flex (I read from some issues with AS2 / AS3...) I try to port the
entire app.
Or: do you know a better method to integrate an existing flash-app
into Flex2? I tried to put the entire Flash app into a swc file and
use this with Flex2 but I didn't get it to work :(
Perhaps somebody has some hints how to do this (but I think that's the
same problem with AS2 / AS3...).
PS: The Flash App is built with MX2004.
Thanks,
bye,
Fritz

this is easily enough done, but before showing you how to do that,
can you
tell us why you want it in onEnterFrame? I suspect that the

are trying.
Here is the code you asked for:
ShowAlert.as
=
package {
import mx.controls.Alert;
import mx.core.UIComponent;
import flash.events.Event;
public class ShowAlert extends UIComponent{
public function ShowAlert(){
this.addEventListener(enterFrame,showAlertBox);
}
public function showAlertBox(event:Event){
this.removeEventListener(enterFrame,showAlertBox);
mx.controls.Alert.show(frame entered);
}
}
}
main.mxml
=
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.macromedia.com/2005/mxml;
xmlns=*
ShowAlert /
/mx:Application
If this is all you want, it can be done more simply as:
Main.mxml
?xml version=1.0 encoding=utf-8?
mx:Application
xmlns:mx=http://www.macromedia.com/2005/mxml;
creationComplete=alert.showAlert()
ShowAlert2 id=alert /
/mx:Application
ShowAlert2.as

package {
import mx.controls.Alert;
public class ShowAlert2 {

}
}
}

At first: thanks for your replies, they sound quite useful.
But:
Could anybody of you be so kind and show me, how to write an AS3 class
and a MXML file which does the following:
The mxml file should be the main file.
The MXML file should invoke the AS class and the AS class should show
an alert box onEnterFrame and then delete onEnterFrame.
I hope somebody can show me how this works, I can't do it :(

[flexcoders] 1st flex 2 project, startup problems
Hi!I want to start a net flex2 project.What I want to do is is to have some mxml files and some as classes.The main app should be a mxml.I've: (mymxml.mxml)?xml version="1.0" encoding="utf-8"?mx:Application xmlns:mx="http://www.macromedia.com/2005/mxml" xmlns="*" mx:Label id="myLabel" text="no Text" / mx:Button click="myLabel.text = myAs.myCounter" //mx:Applicationand: (myAs.as)package { // import Object.Number; import flash.display.MovieClip; import flash.util.*; public class myAs extends MovieClip { public var mc:MovieClip; public var myCounter: Number = 0; public function myAs() { mc. {myCounter = myCounter + 1; } } }}When I hit "run" in Eclipse, the app comes. But when I click the button I'll get the message:ReferenceError: Error #1069: Property myCounter not found on class myAs and there is no default value at mymxml/___Button1_click()What I finally want to do is to bring some AS code from Flash to Flex. But I know, this will get a long way Thanks for you help,byeFritz
