I got the original idea from: http://www.eonflex.com/?p=40 I've got the base case working but I am stuck with 2 problems I cant seem to figure out: 1. Since I am drawing around the text, the actual height of each bubble is greater than that of the Text field, as a result, the last bubble is always chopped off. I have tried explicitly overriding the height getter, and adding some padding, but I cant seem to get it right. You can see an example here: http://test.lambandtunafish.com/bubbles/CommentTest.swf 2. In my layout, I have 2 VBoxes (one nested inside the other). The first vbox shows a form where the user can enter a comment, and the second box has all the comments. In order to ensure that the scrollbars only show up on the second box, I set minHeight=0 on the nested VBox, but then for some reason, some comments' text is shifted to the right. You can see an example here (look at the first comment): http://test.lambandtunafish.com/bubbles/CommentTest-minHeight.swf Rather than posting the code here, I've provided some links: Container: http://test.lambandtunafish.com/bubbles/CommentTest.mxml Bubble: http://test.lambandtunafish.com/bubbles/CommentBubble.as If anyone has any ideas, I would appreciate it.

[flexcoders] Plot chart problem
Ok, I know this is gonna sound really bad on me but I've learned Swiz, figured
out how to simulate a Java-like Thread.wait() using a timer and check a object
for data changes, I've even been able to get around Flex 4...But I am having a
goose chase on where my tooltips are, I get blank tooltip bubbles.
Ok here the case. I am using Plot chart, with the tooltips set to show. When I
hovor over a data point I get a blank tooltip bubble. When I set showAllToolTip
to true I can see them. Now I am dynamicly creating my series , there is a
chance for infinite data sets so the series have to be dynamic. Is there
something I am missing in the code snippetr below?
This is where all my chart's plotting is handled (excuse the pun):
public function sendDataToPlot(evt:TimerEvent):void {
myChart.showDataTips = true;
if(models.message != null || models.message != ){
var myXML:XML = models.message;
var wholist:Array = new Array();
for each(var property:XML in myXML.item.session) {
// Create an Array of unique names.
if (wholist[property] != property)
wholist[property] = property;
}
// Iterate over names and create a new series
// for each one.
for (var s:String in wholist) {
// Use all items whose name matches s.
var localXML:XMLList = myXML.item.(session==s);
// Create the new series and set its properties.
localSeries= new PlotSeries();
localSeries.dataProvider = localXML;
localSeries.yField = visits;
localSeries.xField = when;
// localSeries.
// Set values that show up in dataTips and Legend.
localSeries.displayName = Session + s;
// Back up the current series on the chart.
var currentSeries:Array = myChart.series;
// Add the new series to the current Array of series.
currentSeries.push(localSeries);
// Add the new Array of series to the chart.
myChart.series = currentSeries;
}
} else {
alrtTimer.reset();
alrtTimer.start();
}
[flexcoders] Line Chart Legend problem
I was successful in customizing the datapoints in a line chart with multiple series. The background fill of the datapoint changed according to other values in the xml file. Now my legend which contained the circle color of each series is not displaying. Only the legend label shows up. What am I missing? I know it must be something minor. Thanks.
[flexcoders] Flex4 Tile performance very slow?
Hi
We have a flex3 app, part of which has a dialog box from which the
user can pick a particular graph-type component to add to their
display.
Internally, this is generated with an mx:Tile list, where the
dynamic list of children is created then addChild()-ed to the tile.
This seems fine - but in certain circumstances seems appallingly slow.
To illustrate - if we have a test doing
mx:Tile id = theTile left=10 right=10 top=10 bottom=10/
Then if you do something like the following:
for(var i:int=0;i50;i++)
{
var j:Button = new Button();
j.width = 100;
j.height = 75;
theTile.addChild(j);
}
Then it executes very very fast - too fast to even notice. But if I
replace a 'button' with an mx.charts.LineChart it slows down to be a
couple of seconds, which is on the boundary of being acceptable. But
if I change it to be a (degrafa-based)
com.brightPoint.controls.DegrafaGauge, it's 5 seconds; not what you
want when a user should be flipping through pages quickly.
I tried replacing the mx:Tile with a new Spark BorderContainer, and
it's no better. It feels slower than flex3 was (but that's just a
vague impression).
I suspect I need to be fiddling with ItemRenderers, but I'm not sure
it's going to really help. Are these just badly implemented
components? Is there something else I can do to mitigate the initial
render slowness (e.g: is it actually burning time trying to lay
something out) ?

Re: [flexcoders] Compare two datagrids
Don't compare two datagrids. Compare two datasets. If you need thew view to display what's in common, then you can create your own Filter function and apply it to the underlying data sets. Any changes made to the data will be reflected in the view. On Wed, Mar 31, 2010 at 4:51 PM, cvsikh prebh...@hotmail.com wrote: Hi, I am looking for a solution to compare data in two datagrids.

[flexcoders] Allowing Jpgs saved Within Flex to be named by the user
My app allows a user to take a snapshot of a website and it then saves this
snapshot as a jpg. However what I want is for the user to be able to name this
jpg BEFORE it is saved eg if they type in yahooimage into a textinput component
in my app (imagenameentry) and then click a button to create the image it will
be automatically saved as yahooimage.jpg.
At the moment I've just got the file saving as userimage.jpg but I tried
editing a bit of my code which creates the file to this:-
var file:File =
File.applicationDirectory.resolvePath('assets/images/'imagenameentry.text'.jpg');
This never worked and throws a syntax error but if I use:-
var file:File =
File.applicationDirectory.resolvePath('assets/images/userimage.jpg');
Then it saves but as I say I want the image to be nameable like in the top
example so that whatever the user enters in the imagenameentry box will be set
as the name of the image. What am I doing wrong here and is there another way
to do this?

[flexcoders] Uploading a Specific file rather than browsing
My app allows users to create a user-named jpg like so:-
var enteredimagename:String = imagenameentry.text;
var file:File =
File.applicationDirectory.resolvePath(('assets/images/')+enteredimagename+('.jpg'));
However I now want to allow a user to upload that specfic file automatically to
my server by clicking a button which will simply upload that file WITHOUT
having them browse for it. So basically I need it set up so that when the user
clicks a button whatever name they type into the imagenameentry.text will be
the image that gets uploaded. For example they create an image which they name
yahooimage by typing yahooimage into the imagenameentry text input component.
Once a button is clicked this will save this image as
assets/images/yahooimage.jpg but I want to advance this button click further so
that this specific jpg is then set as the file for upload without browsing for
it. All the examples I've seen use the browse function though which is not what
I want.
How can this be combined with the filereference method or some other way so
that the file to be uploaded can be entered into a textinput component as
described above rather than browsed for?
