Re: [flexcoders] Re: PrintJob & print dialog box

[Frederico Garcia]

You must handle page range by yourself... meaning? you don't send to the 
printjob what you don't want printed. Take a look at the way we did it 
with flexreport (http://www.kemelyon.com/flexreport/0_2rc1/). More info 
on the blog (http://www.kemelyon.com/bts).

Sorry, there's an easier way. BitmapData already implements clone(). 
Here's an example from the Flex Language Reference:

import flash.display.Bitmap;
import flash.display.BitmapData;

var bmd1:BitmapData = new BitmapData(100, 80, false, 0x);
var bmd2:BitmapData = bmd1.clone();

bmd1.setPixel32(1, 1, 0x);

trace(bmd1.getPixel32(1, 1).toString(16)); // 
trace(bmd2.getPixel32(1, 1).toString(16)); // ff00

var bm1:Bitmap = new Bitmap(bmd1);
this.addChild(bm1);

var bm2:Bitmap = new Bitmap(bmd2);
bm2.x = 110;

this.addChild(bm2);


Hope this helps you.

Hi,

you can use this method:

public static function clone(value:ByteArray):ByteArray {
var myBA:ByteArray = new ByteArray();
    myBA.writeObject(value);
myBA.position = 0;
   
return myBA.readObject();
}

Re: [flexcoders] Re: FlexPrintJob: print image AND text [SOLVED]

[Frederico Garcia]

Hi,

I forgot posting that I'd found the reason to my problems. After some 
hours struggling with my code trying to understand why sometimes images 
got printed and sometimes they didn't I've found that the issue was in 
Flash Player (got to the same bug report you mention).

I believe the only solution is make users  update Flash.

Re: [flexcoders] Re: FlexPrintJob not printing multiple formatted lines successf

[Frederico Garcia]

Hi,

Have you tried iterate through each visible line (you can know how many 
lines are visible from verticalScrollPosition) and sum all heights? I've 
been using this method and it's the only reliable way I've found to 
measure the text height.

Also, as John said, you can only make this work with embedded fonts. 
Flash doesn't render text for printing the same way it renders for 
screen (unless the fonts are embedded) and the calculations used the 
screen render, that's why lines get cut off.

You might want to take a look at PrintTextArea which does what you want. 
You can find it here:

http://code.google.com/p/flexreport/source/browse/trunk/flexreport/org/print/PrintTextArea.mxml

Hope this helps,

Frederico Garcia

Re: [flexcoders] Re: printAsBitmap true vs. false

[Frederico Garcia]

Just another annoyance from the "not so great" Flash printing API. 
You're not missing anything, you actually have to choose between vector 
text or transparency. printAsBitmap=false can also give some unpleasant 
surprises since in some versions of Flash Player images just don't show 
at all.
For FlexReport the choice was obvious... Reports are mostly text, and 
it's not a big deal not being able to use transparent backgrounds. If 
you really need transparency you'll have to live with crappy text.
By the way, why do you need the transparency... there are some 
workarounds you can try (such as getting a imagesnapshot of the 
container holding the image)

Kind Regards,

Frederico Garcia

Hi,

As Paul said the Flash printing API is rather primitive but there are 
only a few limitations we can't overcome (being selecting printer one of 
them).
You can take a look at FlexReport at http://www.kemelyon.com/bts It's a 
small framework to make the usage of the Flash printing API a bit easier.

If you feel FlexReport isn't what you need here are some resources which 
might help you getting into printing in Flex.

Hi,

Actually it's possible =)

http://dougmccune.com/blog/2007/06/03/save-a-snapshot-image-of-a-flex-app-without-a-server/

And, what you probably heard of similar to "save the chart as image in 
flex3" is the new ImageSnapshot. From the same blog:

Hi,

I've released PrintTextArea included in FlexReport. You can see a demo 
(with sources) at www.kemelyon.com/bts
To use PrintTextArea you have to do nextPage() while validNextPage. When 
you finish printing you will be at the last page. If you want to print 
again you need to tell PrintTextArea to go again to the first page. This 
is done using reset().
Let me know if yu have any problems.

Frederico Garcia

It only happens when you move the scrollbars? Otherwise it could be 
related to aliasing (with antialias what you see isn't what you print).

Hi,

Before posting questions you should see if anyone has asked them (or 
related) before.

http://www.nabble.com/Scrollbar-Thumb-turn-off-stretch--td11168854.html#a11168854

Here you have exactly the solution for you question (remove arrows).

As I replied in your previous question, check the documentation on 
programmatic skinning:

http://www.adobe.com/devnet/flex/quickstart/skinning_components/

In the doc's they show how to create a borderSkin in actionscript and 
apply it in mxml. Combine the two examples (instead of a border you have 
to create thumbDownSkin, thumbOverSkin, thumbUpSkin and trackSkin) and 
you have your scrollbar with no arrows and changed width.

If you read my previous answer and googled "flex programmatic skin" you 
would already know this. Please don't expect people to always give you 
ready to use code.

Frederico Garcia

Hi,

Flex does not provide any way of doing print preview. You can see a demo 
of FlexReport http://www.kemelyon.com/flexreport/
I will make this project public during the next days.

eg.

if screen size is 1028x768 or 1600x1200, the component should move off

What do you need the screen resolution for? Unless you could make sure 
the app is always fullscreen (wich you can't) the screen resolution 
would almost always be different from the application size.


What matters to you is the application size. And you can easily get that 
value (as Sherif said, component.width+Application.application.width).


Then you just have to trigger a Move effect (by AS or transition):


  
  
  xFrom="{component.x}" 
xTo="{component.width+Application.application.width}"}/> 
  

  

  
  xFrom="{component.x}" xTo="{0}"}/>

  




Now, you need to make sure the component gets off the screen AND it 
stays there if the application is resized. There are a few ways to do 
that, I'll tell you how to do it with Binding.


First, the Binding only should be set when the component is off the screen:


  
  
  xFrom="{component.x}" 
xTo="{component.width+Application.application.width}"} 
*onTweenEnd="bindX()"*/> 
  

  

  
  xFrom="{component.x}" xTo="{0}"}/>

  




Now the actual binding:

private var watcher:ChangeWatcher;
private function bindX():void {
   watcher = 
BindingUtils.bindSetter(_applicationWidht,Application.application,"width");

}

private function unbindX():void {
   if(watcher!=null) {
   watcher.unwatch();  
   }

}

private function set applicationWidht(value:Number):void {
   this.x = component.width+Application.application.width;
}

And that's it. I didn't test this but I think it's at least enough to 
show you a way.


Hope it helps, regards

Hi,

Have been working on a similar component: FlexReport... you can see a 
demo at www.kemelyon.com/flexreport
I advise you that printing in flex isn't has simple has we might think 
at first (I'm trying to simplify that process).

If you're interested mail and I'll be glad to send you the source.

Hi,

I'm not printing external images. I'm printing components (charts). If I 
set
printAsBitmap=true everything is printed but text is blurry. The issue 
only occurs with printAsBitmap set to false. I'll try to find the source 
of the problem and then repost.

Hi Joao,

Try this (not sure if works):

var dateValidator:DateValidator=new DateValidator();
dateValidator.source=dataDeNascimentoTxt;
dateValidator.addEventListener(FlexEvent.VALID,onValidatorValidEventHandler);

private function onValidatorValidEventHandler(event:FlexEvent):void {
event.target.errorString = '';
} 

Tell me if it worked,

Hi Jon,

Thanks for the quick reply. You can see my posts on flexReport and 
PrintTextArea to see what I'm trying to do. Printing is killing me. 
People (specially in organizations) do like to print stuff, and more 
they do like to see what they are about to print before they waste 
paper. And I really don't like to waste countless hours every single 
time I want to print more than a few lines of text.

Now I'm trying to develop a reusable solution to prevew and print 
reports and the only (major) feature missing is printing multiple pages 
of text.

Would you bother to take a look at PrintTextArea 
(http://www.kemelyon.com/printtextarea/) and see if you can give me some 
help? In the meanwhile I'll try to make good use of your tips :)

Regards,

Frederico Garcia

[flexcoders] Font rendering for print

[Frederico Garcia]

Hi,

Does anyone know how to make flash render fonts the same way for screen 
display and printing? I've tried embedding fonts, changing the settings 
for flashType and fontAntiAliasType but I just can't get fonts to 
display the same way. This is causing a lot of trouble since I can' get 
lineMetrics to give me accurate values.

Frederico Garcia

You can use PrintTextArea as is. The bugs are related to screen display 
and the reset() method (for printing twice the same PrintTextArea) missing.

Hi,

I'm making a PrintTextArea component wich is basically a TextArea with 
simillar behaviour to PrintDatagrid. Still has some bugs, so I'll repost 
has soon has I corrected them.

Read the documentation on PrintDatagrid to learn how to use this.

By the way, if someone has corrections or suggestions on this please let 
me know.

Hi,

What if you had a buffer, implemented by an array (or arraycollection) 
of Assets, beeing an Asset something like:

public class Asset {
   private var _source:BitmapData;
   private var _name:String;
   private var _url:String;

   public function Asset() {

   }

   public function set url(value:String):void {
  //load data
   }

   public function get url(value:String):void {
  return _url;
   }

   //getters and setters for name

   //getters and setter for bitmap
}


and the buffer something like:

public class Buffer {
   private var buffer:ArrayCollection = new ArrayCollection();
  
   public function getBitmap(url:String):void {
  //traverse buffer
  //if url is loaded (there is an Asset with that url) return 
buffer[i].bitmap
  //else create asset (asset:Asset = new Asset(); asset.url = 
url) and add to buffer;
   }
}

being Buffer a singleton.

Everytime you needed a image you requested (by url or by name) to the 
Buffer and your image would be loaded only once. Ofcourse you have the 
overhead of traversing the buffer looking for the image, but I think it 
would take an extremely large number of images to make this traversing 
slower than the network time needed to load an image.

Let me know what you think,

Frederico Garcia

Hi,

Did you consider having a singleton like AssetsController wich you 
filled with your assets and then bind to them?

Hi,

I did this (www.kemelyon.com -> Características) by having 2 states, 
each having an Image. Do a transition from state1(fadeIn) to 
state2(fadeOut) and add onTweenEnd to state2. onTweenEnd turns 
currentState = state2 right after changing the source of image1.

Thanks alot! I've been looking for this for a long time...

I've solved my problem (printing charts) by applying a scale matrix 
before I converted the component to BitmapData. My solution is not what 
I really looking for, because everytime I want to scale the capture I 
have do getBitmapData again (getVectorData would be so cool=).

I'll look into your answer.

Hi,

You got me in good mood so here's an example covering both the Timer and 
onEnterFrame timing techniques: http://www.kemelyon.com/timing_example/ 
(right click to view source).

Near the end of making you the example I figured out what was wrong in 
your code. Really simple, so simple I often forget it. STOPPING THE 
TIMER! :) imagine you set the timer to trigger every 3 seconds; after 
one second you close the alert; after half a second you open the alert 
again. After half a second the Timer would trigger and your new born 
alert would be closed.

Tell me if this helped,

Frederico Garcia

Hi,

The code for Timer should work. Not advisable to use at the same time as 
onEnterFrame. Either Timer or onEnterFrame are susceptible to CPU usage. 
But with such an interval (3secs) you should have no problem.

I've used Timer to make a clock (www.kemelyon.com) and it's exact in 
seconds.

How big is the error for Timer (and it takes longer or less than expected)?

[flexcoders] how to duplicate component

[Frederico Garcia]

Hi,

For my flexReport (www.kemelyon.com/flexreport) I need to make a 
duplicate of a component. For example, if I want to print a chart, I 
need to take that chart, resize it and add it to a page. My problem is 
that a component can only be draw inside a container at a time, so if I 
add it to the page it desapears from the original container. I don't 
want to use getBitmapData either because that way when I resize it will 
lose quality.

What I want is having a method like:

var chart2:ColumnChart = cloneComponent(chart1);

or

getVectorData(chart1);

Hope someone can help me,

Regards,

This component works with templates. You have a canvas and add whatever 
you want to it. I tested it with images and graphics. The only problem 
with graphics is that labels get aliased (no way to prevent it) and if 
the text size is too small they get unreadable.

Mail me directly ([EMAIL PROTECTED]) so we can discuss more on it.

Alex,

the value:Object is not intended to be used. It will be an event if 
called by Alert window, null if no argument passed. It's just a 
workaround to maintain current usage (no arguments) but accept 1 
argument of any kind.

Could you please post the code you use to display the Alert? I've been 
trying to recreate your scenario with no success. Alert.show("text"); is 
always centered by default.

Printing from bitmaps is not the best way, specially if you have text 
since it wil be aliased. To print multiple objects insert them inside a 
Canvas and print that Canvas.

Thanks Kevin,

Great post on function binding.

I believe function binding is quite cool, BUT troublesome and needless. 
Binding a property to a function with no parameters is the same as 
binding to a getter. Most Binding issues can be solved using the 
solution I first provided.

I run into the same issue before. Variables in Flex are passed by 
reference, not by value. If you do something like fooFunction(fooVar) 
you'r just passing a reference to the content of fooVar.
In order to add the same component to different containers you have to 
make a clone, or in your case it's easier to just have the source of 
img1 as a parameter and create another Image with the same source.

Hi,

Though I'm no expert in security it's something that always interests 
me, since I mainly work on the health area and they are pretty concerned 
with it.

I already knew riapt, I just think it is too oriented to news on the ria 
world and since I read Ted Patrick's blog every day I usually get them 
first from there. It would be nice if you started posting tips and small 
tutorials.

Well,this is in fact a lot of work. I used this because I wanted to 
surround my main canvas with different colors (like a tile). If you just 
want your canvas centered you have to insert ALL you content inside a 
SINGLE container (canvas, panel, etc...) a center that container inside 
the Application (HorizontalCenter and VerticalCenter).

I think what you'r trying to do is center the application itself. Not 
possible (or at least inside flex, in order to do that you must change 
the html template and add the swf in the middle cell of a 3x3 table)

Well, here's an article about WebOrb.  I would go with BlazeDS though. 
It's based on LCDS, and is in my opinion what most Flex developer using 
Remoting were waiting for a long time.

I've been using amfphp and graniteds. Both are quite easy to use. 
Granite doesn't need J2EE, (see the POJO sections) but it requires 
Tomcat or JBoss to deploy. amfphp as the advantage of being PHP wich is 
much easier to find hosting for.

Soon I'll be posting a tutorial on preparing FB to better develop in 
Java based Remoting frameworks.

I can't help you with Blaze since I've been too busy to experiment with 
it, but the possibility of messaging (the ability to do callbacks) FOR 
FREE in Flash is one of it's coolest features.

Have a VBox as the top level container (top=0;bottom=0;left=0;right=0).  
Insert  one empty Canvas, then an HBox, then another empty Canvas. The 
two Canvas' having width and height of 100% and the HBox the same height 
as your "Application Canvas". Now, inside the Hbox have one empty 
canvas, your "Application Canvas" and finally another empty canvas. The 
empty Canvas' with width=100% and height=100%;

The outline tree would look like:

Applicaton
|-- VBox
  |-- Canvas top
  |-- HBox
  |  |-- Canvas centerLeft
  |  |-- Canvas main
  |  |-- Canvas centerRight
  |-- Canvas bottom

I'd only advise you to do this if you want alot of flexibility in your 
layout. (I did this for http://www.sizemodels.com)

For the most cases it would be enough to have all your content inside a 
Canvas, and set it's verticalCenter = 0 and horizontalCenter = 0.

You must have a file .htaccess inside public_html containing:

SecFilterEngine Off
SecFilterScanPOST Off

If this doesn't work install ethereal and check for the error code 
you're getting from the server.

Not really. You just create one datagrid component. And when you insert 
one object you try to execute a function (your custom code) in THE 
OBJECT. If the object has that function defined it executes it, else it 
fails (throwing a TypeError) and executes de default code.

Here's a sample Object you could had to the CustomDatagrid.

public class CustomObject {
private var fooCounter:int;

public function CustomObject() {
fooCounter = 0; 
}

public function customFunction():void {
   fooCounter++;
}
}

If you added this CustomObject to the previous CustomGrid it would 
execute the /CustomObject.customFunction() /incrementing the fooCounter.
If you added any other Object not implementing customFunction() the 
CustomGrid would execute the defaulte code (the one inside catch).

Hope I was clear enough,

Frederico Garcia

What I meant was having a function on the Object added to the grid, not 
on the grid itself. Something like this:

public class CustomGrid extends DataGrid {

(...)

override public function addElement(value:Object):void {
super.addElement(value);
executeCustomCode(value);
}

public function executeCustomCode(value:Object):void {
try {
value.customFunction();
}
    catch(error:TypeError) {
   // ADD YOUR DEFAULT CODE HERE
}
}
}

The syntax is not correct but it gives you the big picture. To improve 
this you could had a listener on /added/ to the dataProvider that 
triggered the executeCustomCode function.

Hope this helps,

Maybe you could create a function on every object always with the same 
name, and when you had a object to the list you check if th function 
exists. If it does you execute it, else you do nothing. You can see the 
same principle in clonable objects (having a function called /clone()/)

I've run into many problems concerning lists and datagrids not updating 
when the datasource changes. To prevent this kind of problems I usually 
use 2 ArrayCollections (arrays do not fir onUpdate events). One contains 
the data and the other the filtered data (and is the dataProvider). When 
I want to change the values in the list I do something like

[Bindable] private var dataProvider:ArrayCollection = new ArrayCollection();
private var _data:ArrayCollection = new ArrayCollection();
private function set data(value:ArrayCollection):void {
_data = new ArrayCollection();
_data = value;

dataProvider = new ArrayCollection();
dataProvider = applyFilter(value);
}

private function applyFilter(value:ArrayCollection):ArrayCollection{
// (...) apply some filter to value
return value;
}

Joao,

Why don't you use a string based on time instead of a hardcoded one? The 
system would become pretty secure. Even if someone decompiled the client 
it would be much harder to understa

Yes, indeed there was a circular reference to toString. Thanks for the 
correction. The general concept is the same though, and I think it's the 
best way to solve the "bind to function" problem.

I believe you can only bind vars and setters. By binding a function i 
think it will only execute the function once. An easy workaround is to 
have a var containg the result of the toString function and bind the 
property to that var. Something like:

[Bindable] public var stringValue:String = "";
public function toString():String {
stringValue= this.toString();
return stringValue;
}

The Timer is not exact, especially if fired on small intervals. If the 
VM is not able to execute the code it jumps (like flash jumpes frames).
If you are trying to emulate the time frame Timer is not the best method.

Instead create a class extending MovieClip and use onEnterFrame... 
something like this:

public class Effect extends MovieClip {
private var _currentFrame:uint = 0;
private function onEnterFrame(event:Event):void {
_currentFrame++;

//ADD YOUR CODE HERE
}
public function start():void {
this.addEventListener(Event.ENTER_FRAME,onEnterFrame);
}
   
public function end():void {
this.removeEventListener(Event.ENTER_FRAME,onEnterFrame);
}
}

Hope this helps.

Re: Re[flexcoders] port building.

[Frederico Garcia]

Hi,

For a recent project I've developed a client-side template based report
generator with preview, zoom in, zoom out, print, export to pdf (AlivePDF).

If I see interest I'm thinking on releasing the code, and I'm looking
forward for contributers.

You can see a demo  http://www.kemelyon.com/flexreport here

Re: [flexcoders] Solutions for provide a secure access to a Web-Service using Flex

[Frederico Garcia]

I think the best way would be implementing some kind of handshake protocol.
There are plenty of encryption algorithms available. You could save the
passwords encrypted (using sha1) on the DB and then just send it encrypted
on every request. On the server side you just had to check if there was any
matching password before you reply. Still subject to brute force attacks,
but enough for most cases.
