[flexcoders] re-throwing keystrokes to browser?
My flex is running on full screen mode on my browser. Problem is, if the focus is on the flex app, it wont respond to browser keystrokes like CTRL+T (new tab). I can catch the keycode by listening to keydown event but how do I send it to the browser? (prefrably cross-browser solution).
Re: [flexcoders] Re: re-throwing keystrokes to browser?
I want the browser to react on the CTRL-T (new tab). But since the focus is on the flash app, it doesnt do that. So I think I have to catch the keystroke from my flex app and tell the browser that the user wants a new tab. - Original Message From: sdl1326 [EMAIL PROTECTED] To: flexcoders@yahoogroups.com Sent: Thursday, August 21, 2008 6:09:23 PM Subject: [flexcoders] Re: re-throwing keystrokes to browser? To clarify my response. I have done some extensive key trapping in Flash/AS3 where I had to prevent default behaviors in the browser (i.e. F5, F1, etc). In some instances these keys would be required by the Flash App. so what I ended up doing was setting the focus constantly on the browser (via listeners in Flash), trapping the keys, and then sending the event.keyCode back to the Flash App. via ExternalInterface.

[flexcoders] regexp problem
Hi guys, this might be a trivial prob but Im having problem with regexp pattern.
This wont compile:
var singleDatePattern:RegExp = \d{2}(/)\d{2}(/)\d{4};
I've tried this:
var singleDatePattern:RegExp = new RegExp(/\d{2}(/)\d{2}(/)\d{4}/);
but it wont match against the string 08/20/2008. returns false.
I've tried the pattern on http://gskinner.com/RegExr/ and is confirmed to be
correct.

[flexcoders] Data binding prob with custom component
Hi All,
I have a problem with data binding on my custom component.
If my myModel.tokens (arraycollection) was modified somewhere else (i.e. in
front controller)
the set dataProvider function never gets called. The doThisFunction() only
gets called
once, during the ui component instantiation I would guess.
I'm changing the contents of myModel.tokens using only:
myModel.tokens.removeAll();
myModel.tokens.addItem(obj);
Parent Component:
[Bindable]
public var myModel:MyModel;// myModel.tokens is an
arraycollection. MyModel class is marked as Bindable
...
mycomp:CustomLabel id=keywordList dataProvider={myModel.tokens} /
CustomLabel.mxml:
private var _dataProvider:ArrayCollection;
private var dataProviderChanged:Boolean = false;
...
override protected function commitProperties():void {
super.commitProperties();
if (dataProviderChanged) {
doThisFunction();
dataProviderChanged = false;
}
}
...
public function set dataProvider(tokens:ArrayCollection):void {
_dataProvider = tokens;
dataProviderChanged = true;
invalidateProperties();
}
...
private function doThisFunction():void {
//iterate over array and display on screen...
}
How do I make sure the set dataprovider function gets triggered when the
contents of tokens changes? Whats wrong with my code?

I created a component what I call bookmark bar where there are markers that you
can click
to jump/scroll to a particular portion of a list (given the index). Similar to
Eclipse/Flexbuilder when you have
errors and there are markers on the right side pane that lets you jump to the
erroneous line. I am using
this for a datagrid using Canvas as parent component.
var uiComponent:UIComponent = new UIComponent();
addChild(uiComponent);
for (var i:int=0; i_dataProvider.length; i++) {
var bm:Bookmark = _dataProvider[i] as Bookmark;
sprite = new MySprite(); // extends Sprite. Creates an
instance Sprite for each marker
sprite.graphics.lineStyle(3, bm.color, 1, false,
LineScaleMode.NORMAL, CapsStyle.SQUARE);
sprite.graphics.moveTo(x, y);
sprite.graphics.lineTo(x + xOffset, y);
...
sprite.addEventListener(MouseEvent.CLICK, scrollToLine);
sprite.buttonMode = true;
...
uiComponent.addChild(sprite);
}
It works as expected but I noticed it is heavy on CPU and affects the
responsiveness of the
UI. CPU spikes at 55% to 60% even if I only have a few markers (10 to 15).
The lag is very noticeable because just hovering the mouse pointer over the
list,
the item highlighter, delay in rendering the display is very evident.
It doesnt happen on my app when I turn it off.
Am I doing this right? any workaround?

Alex,
It gets clipped but I know its expanding because I have used
resize effect to observe it in slow mo. Its like the renderer is having problem
drawing part of the window region. Tried using the latest SDK/Flash Plugin.
same thing.
Screenshot of it looks like exactly :
http://www. geocities.com/poweribo/clipped.png
Should be like this:
http://www. geocities.com/poweribo/clipped2.png
It turns out that the problem was more of PopupButton issue.
It behaves as expected if TitleWindow is not a child of popup.
On a somewhat related note, there is another serious prob with PopUpButton
when used with ViewStack. The value of popup attribute of PopUpButton
mysteriously gets set to null when you navigating thru the view stack.
I'm actually surprised the issue was closed in Adobe Bugbase bec

[flexcoders] word highlighting
Have anyone worked on something like this before? What I want is to highlight
the word by changing the background color of each keyword from a
sentence/paragraph.
Here is my code so far:
private function applyTextHighlight(textField:UIComponent,
listOfWordPositions:Array):void {
var textArea:TextArea = TextArea(textField);
var tr:TextRange = new TextRange(textArea);
tr.htmlText = textArea[htmlText];
for (var i:int=0; ilistOfWordPositions.length; i++) {
var metaWord:WordPositions = listOfWordPositions[i];
tr.beginIndex = metaWord.startIndex;
tr.endIndex = metaWord.endIndex;
tr.htmlText = formattedText(tr.text, metaWord.color);
//tr[color] = metaWord.color;
//tr[fontWeight] = bold;
//tr[fontSize] = 12;
}
}
private function formattedText(text:String, color:uint):String {
return FONT style='BACKGROUND-COLOR: + color + ' + text +
/FONT;
}
TextRange seems to be very limited on how much you can format your html text so
I'm not surprised it doesnt really fully support HTML. Any workaround to get a
similar behavior?
Changing the text color, size and weight works though (see commented out lines).

Re: [flexcoders] word highlighting
Frederico,
I did try it. I used the highlighter on a custom item renderer. looks good on
initial display but when you try scrolling the list component, the display
screws up. the rectangular box used as background doesnt flow with the
text. something to do with relative x,y positioning. looks like it was not
designed to be used for renderers.

[flexcoders] working with ICollectionView and IViewCursor
I wanted to update my datagrid / arraycollection with data coming from server. the list is sorted by date field by default. if the record item exists in the list, i will replace the existing item with the new one, and if its not on the list, I will add it to the list. Here is the catch, updates should be done by insert sort using uniqueId field while additions done by insert sort using the date field. How do I accomplish this? I've tried creating two sets of Sort/ICollectionView/IViewCursor, one for update and another for addition. Unfortunately it did not work. Arent these views and cursors only a virtual window to the actual collection data? -is this the right way to do it?--- var sortByUniqueKey:Sort = new Sort(); sortByUniqueKey.fields = [new SortField(uniqueId)]; var sortByStartTime:Sort = new Sort(); sortByStartTime.fields = [new SortField(dateField)]; var viewSortedByUniqueKey:ICollectionView = new ArrayCollection(items.toArray()); viewSortedByUniqueKey.sort = sortByUniqueKey; viewSortedByUniqueKey.refresh(); var viewSortedByStartTime:ICollectionView = new ArrayCollection(items.toArray()); viewSortedByStartTime.sort = sortByStartTime; viewSortedByStartTime.refresh(); var forUpdateCursor:IViewCursor = viewSortedByUniqueKey.createCursor(); var forAdditionCursor:IViewCursor = viewSortedByStartTime.createCursor(); do stuff here on individual cursors ... - I noticed calling ICViewSortedByUniqueKey.refresh() and ICViewSortedByUniqueId.refresh() affects the same reference collection.

Assunto: [flexcoders] value object binding problem
I have this VO binding from java to as3:
JAVA / JDK6 - LookupStuff.java
public class LookupStuff {
private ListClassA attributeA;
private ListClassA attributeB;
private MapString, ListClassB attribute1;
private MapString, ListClassC attribute2;
private MapString, ListClassD attribute3;
...setter/getters...
}
-
AS3 - LookupStuff.as
[RemoteClass(alias=my.java.package.LookupStuff)]
import mx.collections.ArrayCollection;
[Bindable]
nbs p;public class LookupData {
public var attributeA:ArrayCollection;
public var attributeB:ArrayCollection;
public var attribute1:ArrayCollection;
public var attribute2:ArrayCollection;
public var attribute3:ArrayCollection;
}
--
private function myHandler(event:ResultEvent):void {
var lookup:LookupStuff = event.result as LookupStuff;
// lookup is null! why???
}
Im getting null when my actionscript handler (thru RemoteObject / ResultEvent)
finally gets event.result. Anybody knows why? Can a Map and List
interfaces easily maps to an AS3 ArrayCollection?
I've verified that my java code is returning a good return value (not null).

[flexcoders] blazeds / livecycle ds question
I know I have asked this question before but unfortunately I havent found an answer yet :P. Maybe Mr. Vroom can shed some light on this? tia. what if there is at least 500 users using the client, assuming the server is configured to handle the load hardware-wise, does the blazeds keeps instances of this remoteobjects? all 500 of them? or does it use pooling and keeping at least half of them and have them re-use objects like how EJB (passivate/activate) does? (for java devs in this list). My understanding of how the DS work behind the scenes so pardon me if the questions are inapplicable :P.

[flexcoders] adjust row height of datagridcolumns?
Hi guys, I have a datagrid, and I have created custom item editor for each column but is bigger than the usual row height (equivalent to 3 lines and purposely designed it that way). the itemEditor gets displayed when I click on it but the actual height of the row doesnt adjust and scroll bars appears, rendering it all cramped and you'll hardly see anything. How do I make it adjust the height automatically when itemEditor springs into action? preferably something that I can attach a resize effect. tia. - Be a better friend, newshound, and know-it-all with Yahoo!

Re: [flexcoders] BlazeDS in the integrated Tomcat configuration
it means blazeds was pre-configured to run on tomcat and it came with the download. if you unzip the downloaded file, you'll see that there is a tomcat directory included. and if you take a look at /tomcat/webapps/ , youll notice that a sample web application using blazeds is pre-installed. unzip and run. hworke [EMAIL PROTECTED] wrote: Hi in the BlazeDS configuration document they are talking about integrated Tomcat- what does in really mean? How do I know if my tomcat is integrated Tomcat or not.

Re: [flexcoders] connection downtime in flex/blazeds?
Steve, I'm curious, If the AS3 version of Consumer class can do it and I'm assuming its identical in terms of functionality, why did you guys decided to use FABridge instead? Also I have a follow up question, a lil diff topic and the concern is on the scalability issue: what if there is at least 500 clients using the client, assuming the server is configured to handle the load hardware-wise, does the blazeds keeps instances of this remoteobjects? all 500 of them? or does it use pooling and keeping at least half of them and have them re-use objects like how EJB (passivate/activate) does? (for java devs in this list). Regards, Stephen Cutter (Flex Related) [EMAIL PROTECTED] wrote: We went through this recently with an HTML/AJAX based AIR app, utilizing the Flex/Ajax Bridge to communicate with blazeDS. We found a method in the Consumber obj that basically checked the connection and re-subscribed if the connection had been broken. The Flex/Ajax Bridge Consumer object is basically a JavaScript version of the AS3 class within Flex (same API, mostly), in fact we used the AS3 API docs to figure out it's usage (since the FAB is not well documented.)

[flexcoders] connection downtime in flex/blazeds?
Is there a way for a flex client to know that the connection got cut off from a blazeds backend? (ie. server was restarted). i have a flex grid that gets updated regularly (partial data, accumulates overtime) by a backend service using pub/sub messaging.. but if the server gets rebooted, the server should push the whole list of data (not partial). whats the best way to solve this kind of prob? - Be a better friend, newshound, and know-it-all with Yahoo!

[flexcoders] Sort - findItem - compareFunction prob
Hi I'm having problem with sorting, the compiler says :
error:
[mxmlc] C:\stephen\Main.mxml(51): Error: Implicit coercion of a value of
type Boolean to an unrelated type String.
[mxmlc] insertionIndex = sort.findItem(forAddition[i], Sort.
LAST_INDEX_MODE, true, compareTitles);
[mxmlc]
compiler documentation says:
* 1067
* Implicit coercion of a value of type _ to an unrelated type _.
* You are attempting to cast an object to a type to which it cannot be
converted. This can happen if the class you are casting to is not in the
inheritance chain of the object being cast. This error appears only when the
compiler is running in strict mode.
code:
--
private function compareTitles(itemA:MyObj, itemB:MyObj):int {
var valueA:String = itemA.title;
var valueB:String = itemB.title;
return ObjectUtil.stringCompare(valueA, valueB);
}
---
// forAddition is pre-sorted from the backend
var forAddition:ArrayCollection = ..some data..;
// Check insertion index to maintain sorting order
var sort:Sort = new Sort();
var insertionIndex:int = 0;
for (var i:int=0; iforAddition.length; i++) {
insertionIndex = sort.findItem(forAddition[i],
Sort.LAST_INDEX_MODE, true, compareTitles);
items.addItemAt(forAddition[i], insertionIndex);
}
---
What changes do I need to do fix the error? I dont see any datatype mismatch at
the method parameters.
Regards,
Stephen

RE: [flexcoders] Sort - findItem - compareFunction prob
second arg?
sort.findItem(forAddition[i], Sort.LAST_INDEX_MODE, true, compareTitles);
The 2nd argument is a constant provided in Sort class. I used whats available.
The other 2 options are :
Sort.LAST_INDEX_MODE
Sort.ANY_INDEX_MODE
Care to give a correct sample usage of Sort.findItem()? I cant find an example
anywhere. Thanks.

Agh. How could I miss that. ive depended too much on IDE and its showing now
that im using plain text editor :P. Thanks a bunch.
