I'm having a problem with labels disappearing on Flex's datavisualization.swc charts that are built on our build server via ANT and the Flex 3.3 SDK. I've made sure that our license is applied properly on the build server (hence no water marks), and I've made sure the exact same datavisualization.swc was copied from my dev machine into the Flex3.3SDK/frameworks/libs directory.
Any ideas? Could it be a font problem? (Though we're really only using default fonts.)
Here's the problem, missing axis labels on the build server

Here's how it's supposed to look with labels (taken on my local development machine)

I got it working using the helpful information I found at the Flex Coders archive.
Basically, in an initalize event handler, I added the following code:
var ccClassFactory:ContextualClassFactory = new ContextualClassFactory(ChartAxisTextLabel);
ccClassFactory.moduleFactory=this.moduleFactory;
var hAxisRenderer:AxisRenderer = new AxisRenderer();
hAxisRenderer.axis = hAxis;
hAxisRenderer.labelRenderer=ccClassFactory;
var vAxisRenderer:AxisRenderer = new AxisRenderer();
vAxisRenderer.axis = vertAxis;
vAxisRenderer.labelRenderer=ccClassFactory;
lineChart.horizontalAxis=hAxis;
lineChart.verticalAxis=vertAxis;
lineChart.horizontalAxisRenderers = [ hAxisRenderer ];
lineChart.verticalAxisRenderers = [ vAxisRenderer ];
Also, I had to create the class:
public class ChartAxisTextLabel extends Label
{
public function ChartAxisTextLabel()
{
super();
}
override public function set data(value:Object):void
{
super.data = value;
text = value.text;
}
}

I have run into a road block developing my Codename One app. One of my classes in my project parses 3 specific html "td" elements from a website and saves the text to a string where I then input that text data into a Codename One multibutton. I originally used jSoup for this operation but soon realized that Codename One doesn't support 3rd party jar files so I used this method as shown below.
public void showOilPrice() {
if (current != null) {
current.show();
return;
}
WebBrowser b = new WebBrowser() {
#Override
public void onLoad(String url) {
BrowserComponent c = (BrowserComponent) this.getInternal();
JavascriptContext ctx = new JavascriptContext(c);
String wtiLast = (String) ctx.get("document.getElementById('pair_8849').childNodes[4].innerText");
String wtiPrev = (String) ctx.get("document.getElementById('pair_8849').childNodes[5].innerText");
String wtiChange = (String) ctx.get("document.getElementById('pair_8849').childNodes[8].innerText");
Form op = new Form("Oil Prices", new BoxLayout(BoxLayout.Y_AXIS));
MultiButton wti = new MultiButton("West Texas Intermediate");
Image icon = null;
Image emblem = null;
wti.setEmblem(emblem);
wti.setTextLine2("Current Price: " + wtiLast);
wti.setTextLine3("Previous: " + wtiPrev);
wti.setTextLine4("Change: " + wtiChange);
op.add(wti);
op.show();
}
};
b.setURL("https://sslcomrates.forexprostools.com/index.php?force_lang=1&pairs_ids=8833;8849;954867;8988;8861;8862;&header-text-color=%23FFFFFF&curr-name-color=%230059b0&inner-text-color=%23000000&green-text-color=%232A8215&green-background=%23B7F4C2&red-text-color=%23DC0001&red-background=%23FFE2E2&inner-border-color=%23CBCBCB&border-color=%23cbcbcb&bg1=%23F6F6F6&bg2=%23ffffff&open=show&last_update=show");
}
This method works in the simulator (and gives a "depreciated API" warning), but does not run when I submit my build online after signing. I have imported the parse4cn1 and cn1JSON libraries and have gone through a series of obstacles but I still receive a build error when I submit. I want to start fresh and use an alternative method if one exists. Is there a way that I can rewrite this segment of code without having to use these libraries? Maybe by using the XMLParser class?
The deprecation is for the WebBrowser class. You can use BrowserComponent directly so WebBrowser is redundant in this case.
I used XMLParser for this use case in the past. It should work with HTML as it was originally designed to show HTML.
It might also be possible to port JSoup to Codename One although I'm not sure about the scope of effort involved.
It's very possible that onLoad isn't invoked for a site you don't actually see rendered so the question is what specifically failed on the device?
For those familiar with automated testing tools, you know that they all have some kind of "object repository" that stores a mapping of UI elements with identifiers. I have found this to be indispensible and I want to duplicate this for webdriver. Has anyone done this ? Any tips ? Google not helping on this one. C# examples if you can, thanks
I use Webinator (which wraps around WebDriver) but the idea is the same - I usually do a static "Map" class like so:
public static class CollectionMap
{
public static Locator
LocatorTitle = new Locator(FindBy.Id, "Title"),
LocatorDescription = new Locator(FindBy.Id, "Description"),
LocatorSave = new Locator(FindBy.Id, "submit"),
LocatorDelete = new Locator(FindBy.XPath, "//*[contains(#class,'deleteBox')]/a"),
LocatorDeleteConfirm = new Locator(FindBy.Id, "delete-collection-dialogConfirmationLink"),
LocatorCancel = new Locator(FindBy.Id, "cancel");
}
Used like this:
web.Click(CollectionMap.LocatorSave, WaitUntil.AjaxOrPostCompleted());
I am creating multiple classes containing mappings to locators. Each class corresponds to a logical grouping of screen elements.
public class TopLevel
{
public const string username = "ctl00_ctl00_Main_Main_txtUsername";
}
I'm new to Flex and am trying to port a pure Flash/AS3 card game to Flex 4.5.
It works mostly well, but I'm missing few puzzle parts there:
I've created a custom component based on UIComponent representing a deck of cards (which are an array of Sprites or MovieClips):
In the original pure Flash/AS3 game I was using Tween for the 3 cards at the table - to show the game user, who has put which card (by sliding them towards playing table middle):
import fl.transitions.*;
import fl.transitions.easing.*;
public class Deck extends UIComponent {
private var _card:Array = new Array(3);
private var _tween:Array = new Array(3);
....
override protected function createChildren():void {
_tween[YOU] = new Tween(_card[0], 'y', Regular.easeOut, _card[0].y + 40, _card[0].y, .5, true);
_tween[LEFT] = new Tween(_card[1], 'x', Regular.easeOut, _card[1].x - 40, _card[1].x, .5, true);
_tween[RIGHT] = new Tween(_card[2], 'x', Regular.easeOut, _card[2].x + 40, _card[2].x, .5, true);
....
However Flash Builder 4.5 doesn't seem to know fl.transitions.* packages at all?
Does anybody please have an advice on how to use Tween here?
Like I've written the rest (my custom Flex component, moving card-Sprites around, etc.) works well. Only the Tween lines had to be commented.
Thank you!
Alex
Take a look at the Tweener class on Google Code. With it you can specify and object, and a map of its properties and their desired values, along with time, and it will 'tween' those properties from their current to their desired values.
Tweener.addTween(yourCard, {y:50, time:1});//for a 1 second tween
My first knee-jerk reaction has been to add flash.swc (delivered by Flash CS Pro) to the Flex build path and then:
import fl.transitions.*;
import fl.transitions.easing.*;
can be used again.
But in the long-term I will probably write my own function to move the playing cards and run it on Event.ENTER_FRAME. Because I don't want to include Tweener or Tweenlite libraries for mere card sliding.
_tween[0] = _card[0].y;
_tween[1] = _card[1].x;
_tween[2] = _card[2].x;
....
_card[0].y = _tween[0] + 20;
addEventListener(Event.ENTER_FRAME, slideCardYou);
_card[1].x = _tween[1] - 20;
addEventListener(Event.ENTER_FRAME, slideCardLeft);
_card[2].x = _tween[2] + 20;
addEventListener(Event.ENTER_FRAME, slideCardRight);
....
private function slideCardYou(event:Event):void {
if (_card[0].y-- < _tween[0])
removeEventListener(Event.ENTER_FRAME, slideCardYou);
}
private function slideCardLeft(event:Event):void {
if (_card[1].x++ > _tween[1])
removeEventListener(Event.ENTER_FRAME, slideCardLeft);
}
private function slideCardRight(event:Event):void {
if (_card[2].x-- < _tween[2])
removeEventListener(Event.ENTER_FRAME, slideCardRight);
}
Also I've looked at mx.effects.Tween and spark.effects.Animate but they seem to be more appropriate for UIComponents and not Sprites as in my case.
I have an Movie Clip in Flash that have subobject of button type which has subobject of input text and movie clips. Right after creation core Moveclip all subobject are set to null, when I expect them to be valid objects.
// hierarchy:
// core:MC_Core_design
// button_1:B_Mybutton
// text_name // dynamic text with instance name
// mc_icon // movie clip with instance name
var core:MC_Core_design = new MC_Core_design();
addChild(core);
core.button_1.text_name.text = "hello world"; // error: text_name is null
core.button_1.mc_icon.visible = false; // error: mc_icon is null
MC_Core_design was created in Flash and exported to Actionscript. I've done this for button_1 class aswell. The code was written using Flex.
When I comment out both lines that result in error I get correct view of the core Movie clip with all subobject.
How can I set subobject properties right after object creation?
You need to listen for the Event.INIT from the class when it is created. (If you are not embedding a symbol using the Embed metatag then Flash takes a few milliseconds to initialize the loaded movieclip). This does not seem to be a problem if the Flash IDE swf/swc does not contain any actionscript)
The issue is sometimes it can be really quick, so it fires the INIT event before you get a chance to attach the event listener to the object. so you can't just attach it after you instantiate the object.
A work around is to embed the swf as a byte array, then use the loader class to load the embedded bytes (This lets you set the event listener before calling load).
e.g.
[Embed(source="assets.swf", mimeType="application/octet-stream")]
private var assetBytes:Class;
private var clip:MovieClip;
private var loader:Loader;
public function LoadBytesExample()
{
loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.INIT, onAssetLoaded);
loader.loadBytes(new assetBytes());
}
private function onAssetLoaded(e:Event):void
{
var loader:Loader = (e.currentTarget as LoaderInfo).loader;
(e.currentTarget as LoaderInfo).removeEventListener(Event.INIT, onAssetLoaded);
clip = loader.content as MovieClip;
this.addChild(clip);
clip.someTextField.text = "HELLO WORLD";
}
Sorry for the formatting, just wrote that off the top of my head
And the syntax for embedding the symbol (You won't need to load this via a loader as the actionscript in the external swf/swc is stripped).
[Embed(source="assets.swf", symbol="somesymbol")]
private var assetSymbol:Class;
private var clip:MovieClip;
public function LoadSymbolExample()
{
clip = new assetSymbol();
clip.sometext.text = "Hello World";
}
If I see it right, button_1:B_Mybutton is not yet initialized.
I mean something like : button_1:B_Mybutton = new B_Mybutton();
About the other two variables text_name & mc_icon as you describe if they have been initialized already (as you term them as instance names), Iguess they should not give you any problem.
Also I asssume that you are setting access modifiers to all as public.
If you still have problem... pls share how all the required variables are defined. Just the relevant part would be enough.
Have a real puzzler here. I'm using Atalasoft DotImage to allow the user to add some annotations to an image. When I add two annotations of the same type that contain text that have the same name, I get a javascript permission denied error in the Atalasoft's compressed js. The error is accessing the style member of a rule:
In the debugger (Visual Studio 2010 .Net 4.0) I can access
h._rule
but not
h._rule.style
What in javascript would cause permission denied when accessing a membere of an object?
Just wondering if anyone else has encountered this. I see several people using Atalasoft on SO and I even saw a response from someone with Atalasoft. And yes, I'm talking to them, but it never hurts to throw it out to the crowd. This only happens in IE8, not FireFox.
Thanks, Brian
Updates: Yes, using latest version: 9.0.2.43666
By same name (see comment below) I mean, I created default annotations and they are named so they can be added with javascript later.
// create a default annotation
TextData text = new TextData();
text.Name = "DefaultTextAnnotation";
text.Text = "Default Text Annotation:\n double-click to edit";
//text.Font = new AnnotationFont("Arial", 12f);
text.Font = new AnnotationFont(_strAnnotationFontName, _fltAnnotationFontSize);
text.Font.Bold = true;
text.FontBrush = new AnnotationBrush(Color.Black);
text.Fill = new AnnotationBrush(Color.Ivory);
text.Outline = new AnnotationPen(new AnnotationBrush(Color.White), 2);
WebAnnotationViewer1.Annotations.DefaultAnnotations.Add(text);
In javascript:
CreateAnnotation('TextData', 'DefaultTextAnnotation');
function CreateAnnotation(type, name) {
SetAnnotationModified(true);
WebAnnotationViewer1.DeselectAll();
var ann = WebAnnotationViewer1.CreateAnnotation(type, name);
WebThumbnailViewer1.Update();
}
There was a bug in an earlier version that allowed annotations to be saved with the same unique id's. This generally doesn't cause problems for any annotations except for TextAnnotations, since they use the unique id to create a CSS class for the text editor. CSS doesn't like having two or more classes defined by the same name, this is what causes the "Permission denied" error.
You can remove the unique id's from the annotations without it causing problems. I have provided a few code snippets below that demonstrate how this can be done. Calling ResetUniques() after you load the annotation data (on the server side) should make everything run smoothly.
-Dave C. from Atalasoft
protected void ResetUniques()
{
foreach (LayerAnnotation layerAnn in WebAnnotationViewer1.Annotations.Layers)
{
ResetLayer(layerAnn.Data as LayerData);
}
}
protected void ResetLayer(LayerData layer)
{
ResetUniqueID(layer);
foreach (AnnotationData data in layer.Items)
{
LayerData group = data as LayerData;
if (group != null)
{
ResetLayer(data as LayerData);
}
else
{
ResetUniqueID(data);
}
}
}
protected void ResetUniqueID(AnnotationData data)
{
data.SetExtraProperty("_atalaUniqueIndex", null);
