Re: [flexcoders] click event handler of datagrid, make it fire on rows only

Listen to itemClick on datagrid, It fires only when an item of the datagrid
is clicked.

If the item renderer is not present in the listItems[0] array, that mean

thanks that event does work better, but hopefully this can be expanded

RE: [flexcoders] Flex Component still active, even know TitleWindow it resides in, is deleted -

[Alex Harui]

You can't really blow things away in AS3 (or Java).  You kill all
references to them and they go away when garbage collected.  If you are
listening to the app model, it means the app model has a reference to
the event listener and thus it won't go away.  Use weak references or
clean up when removed from the display list.

Hello All,

I have a WEIRD problem, and I am hoping you can all shed some light on
this.

I have a Popup TitleWindow which serves the purpose of displaying
details from a Master Grid. Among all the other controls housed within
the TitleWindow, I am using the  Component, which monitors
a Boolean Value residing in my ApplicationModel.

Once the user is finished looking at the Details, they must close the
Window. I am using the PopUpManager.removePopUp() method of closing the
TitleWindow, which should in essence, blow away the TitleWindow itself,
in addition to all the Controls that reside within it.

Even know the TitleWindow gets closed, I am still getting Trace Messages
outputted to my custom Debug Window (which demonstrates the fact, that
my ObserveValue Component is still active & functioning). A quick note,
I am tracing the output so that I can monitor my variables during
development of my app.

How is this possible??

I must get to the bottom of this ASAP, as this is causing some problems
with the rest of my application.

Thanks in advance for any help you can throw my way.

[flexcoders] Re: Inverted charts

Ya sure.

Here's a snapshot.

http://oss.oetiker.ch/rrdtool/

But I guess now that I think about it, all I need to do is plot the 
second line series with a negative value (so that it gets plotted 
below the x axis) and return the positive value in the labelFunction 
of Linear Axis (so that now a value 10 in second line series gets 
plotted at -10, however the label shows the value 10) This way I can 
have two y axes, one running upwards and one running downwards, 
pretty much what I wanted. Not sure but wil try with this approach. 
Lets see.

For custom styles I recommend you to add style metadata to the class like

You'll need to use a custom renderer for your bar series items, and then

RE: [flexcoders] stage.stageWidth/stageHeight lies in standalone player?

I think SAFlashPlayer might do a quick resize so if you check later it
has the right size.  Try tracing on "enterFrame" events.

 

In general, we do very little in the constructors.  There  is an INIT
method which is used to kick off real work.

Hi all,

I'm trying to base some calculations on the stageHeight and
stageWidth, but I end up getting 636 and 464 every single time for
stageWidth and stageHeight (resp), no matter what parameters I give
for -default-size. I'm running the swf in the standalone player and
I've built it with the SDK.

When the swf loads, and it looks like the size I specify for
-default-size, but the actual values returned by those properties
don't match.

Here's a pared down example:

package {
import flash.display.Sprite;
public class Test extends Sprite {
function Test() {
trace([stage.stageWidth, stage.stageHeight]);
}
}
}

> mxmlc -default-size 200 200 Test.as

The trace output shows "636,464" when you run the resulting swf even
though the standalone player looks like it's 200x200.

Is this a bug in the standalone player?

RE: [flexcoders] removeItemAt combined with getItemAt - Manipulating an arrayCollection

You'd have to scan the arraycollection.  I wouldn't use an AC in a

you can remove faster.  The filter function should use for..in to
iterate the fields.

Subject: [flexcoders] removeItemAt combined with getItemAt -
Manipulating an arrayCollection

 

Hello All, great group here. Delighted to have stumbled upon it.

I have an arrayCollection which is used to pass info to a function which
filters an XMLList. 
The arrayCollection, in an ideal world, would change in size and content
based on user 
selections of a series of checkboxes. (i.e. check a box, and add another
filter criteria to 
the arrayCollection, uncheck the box and the criteria gets removed and
the filter rerun).

Here is the arrayCollection:
[Bindable]
public var fields:ArrayCollection = new ArrayCollection([{fieldTag:
"big", value:"t"}, 
{fieldTag: "small", value: "t"}]);

The function in this case would return all items whose node named "big"
AND "small" 
matched "t". 

How can I use removeItemAt and getItemAt in a function to pass in 1
argument to remove 
an element of the arrayCollection. Say for example I wanted to remove
the element whose 
fieldTag was "big" but I did not know where it was in the
arrayCollection. Something like 
this worked when the array was not multidimensional:

fields.removeItemAt(arr.getItemIndex("big");

I would love to put this mess to bed, can anyone shed some light on
this?

Thanks a bunch.

Re: [flexcoders] Change Object Reference

[Kevin]

i couldn't get either of these solutions to work.  When I reset the  
vo variable to nul (or new Object), it still modifies the object on  
the model.  I could be doing something wrong, but for now, i decided  
to instantiate an entirely new super class each time the vo changes.


I'll look into this a little more and see if I can do what I want...

thanks, Kevin

Re: [flexcoders] Change Object Reference

[Michael Schmalle]

Hi,

I would think that setting;

vo = null;

then

vo = someNewObject

would unlink the reference.

OR

vo = new Object();

then

vo = someNewObject

Peace, Mike

Re: [flexcoders] summing a value in an arrayCollection?

Need to correct (add) one line. Forgot to add the cursor.moveNext():

var cursor:IViewCursor = myAC.createCursor();
var sumPop:int = 0;

var myObject:Object;
while (!cursor.afterLast) {
   myObject = cursor.current;
   sumPop += myObject.population;
   cursor.moveNext();

One of the ways would be to traverse your ArrayCollection with a cursor:

[flexcoders] removeItemAt combined with getItemAt - Manipulating an arrayCollection

[michaelmatynka]

Hello All, great group here.  Delighted to have stumbled upon it.

I have an arrayCollection which is used to pass info to a function which 
filters an XMLList.  
The arrayCollection, in an ideal world, would change in size and content based 
on user 
selections of a series of checkboxes.  (i.e.  check a box, and add another 
filter criteria to 
the arrayCollection, uncheck the box and the criteria gets removed and the 
filter rerun).

Here is the arrayCollection:
[Bindable]
public var fields:ArrayCollection = new ArrayCollection([{fieldTag: "big", 
value:"t"}, 
{fieldTag: "small", value: "t"}]);

The function in this case would return all items whose node named "big" AND 
"small" 
matched "t".  

How can I use removeItemAt and getItemAt in a function to pass in 1 argument to 
remove 
an element of the arrayCollection.  Say for example I wanted to remove the 
element whose 
fieldTag was "big"  but I did not know where it was in the arrayCollection.  
Something like 
this worked when the array was not multidimensional:

fields.removeItemAt(arr.getItemIndex("big");

I would love to put this mess to bed, can anyone shed some light on this?

Thanks a bunch.

[flexcoders] Image click handler

[Cesare Rocchi]

Hello everybody,

I am experimenting with Flex.
I started from official examples, from Adobe. 
Particularly this one: http://www.adobe.com/devnet/flex/quickstart/httpservice/


Looking at the demo I thought it would have been nicer to have the picture of 
page open when the picture itself, and not the link button below, is clicked.
I noticed that 


Compiled (no error) and tested. I click on the image and it does not happen 
anything. Link button still works.
Isn't the same action fired from 2 different 'places' in the ui?
Looks very very strange to me. 
Any idea?

ps. I tested other functions on image click (e.g. Alert.show('hello')). They 
work. What's wrong? Is the event considered in a different way?

Thanks in advance,

-c.

[flexcoders] Chart snapshots

[simonjpalmer]

I have a requirement to be able to "copy and paste" a chart from my
flex app to another application via the clipboard.  The chart has to
come exactly as it appears on the screen, almost like an
alt-printscreen, but only the portion of the screen displaying the
chart.  

Has anyone tried anything like this?

I spotted a display object method called cacheAsBitmap which seems to
be an optimisation for rendering, but I wondered if it was possible to
get access to the display bitmap.

Any clues?

Re: [flexcoders] summing a value in an arrayCollection?

Just another option:

[flexcoders] Set size of the SWF application depending on parameters

[jairokan]

Hi,
Here's an example:
package com.mypackage { [SWF(width="320", height="470",
backgroundColor="#FF9966")]  public class MainApplication extends
Sprite { public function MainApplication() {
addChild(childObjectInSamePackage); } } }  The first line
after package declaration sets the Width and  Height of the swf file.  I
have a Utils class with static variables, for example Utils.width and
Utils.height. I tried to use these variables in that declaration but I
have compile time error. I'm trying this: [SWF(width=Utils.width,
height=Utils.height, backgroundColor="#FF9966")] But it doesn't compile.
Any suggestions how to set up these two parameters with variables?

Regards
Jamal
