Flex :: HitTestPoint Not Giving Correct Results
Sep 27, 2010
I have a movie clip on which I have added a MouseEvent.MOUSE_OUT listener.[code]...
Now the logic is to remove the movie clip on MOUSE_OUT and add it back to stage on MouseOver of another button. The intended functionality is like a slider showing some info
The MouseEvent.MOUSE_OUT firing in this case is not functioning always as expected. When I move the mouse out of the moveclip fast it fires. If I moveout very slowly it does not fire and consequently the movieclip remains on the stage. [code]...

I believe I've got this set up to where you can test it out of the box. (Just add photo.jpg)
If you're getting the same results I am, there's a few things that aren't right. One, the main movieclip looks to be duplicated. The other is it's tracing something that shouldn't be traced, a percentage value and some weird random fraction (1.180283....etc). I've removed all the trace statements, which leads me to ask, is there a Flash cache of some sort? I know in past versions the file size would stay the same unless you renamed the fla file.. there something like that for classes?
I know there's a lot of video keywords, it will eventually load video.

My AS3 A* pathfinding implementation sometimes doesn't returns the most efficient route, rather like this:[code]The problem: i should have a total score of (distance to end) 30 + (distance from start) 10 = 40, while the tile above i should have a total score of (distance to end) 40 + (distance from start) 14 = 54. Why is 54 being picked instead of 40, I don't know - I use this to find the node with lowest total score on the open list:[code]

I have a timer to try and have my main timeline frame change every X amount of time. I just would like to cycle the frames as if they were an image slideshow or something. It works almost works by this I mean It will cycle frames 1-4 but then it wont go back to 1 with this code. It will go to frame 2 after frame 4 then the timing and randomness get even worse.[code]

Which one is more efficient? Or is there even a noticeable difference? I did tests of a circle moving closer to a square and stopping when hitTestPoint returns true. The square was at 0 and the circle was at 500. My first test I did using hitTestPoint the entire time, my second test I did by checking the distance (Pythagorean Theorem way) and if it's below 50 then check with hitTestPoint.
I compared the FPS of each test but they were the same at 30 FPS with 200 circles and at 11-12 FPS with 500 circles. I thought the first test would be slower because I was testing every pixel the entire time while the second test I was only calculating the distance for the most part before testing every pixel.

In flex, I am using
canvasEdit.setStyle("borderColor", 0x0134FF);
canvasEdit.setStyle("borderThickness", 3);
note: canvasEdit is of type Canvas.
But I am not able to put border on the sides of canvas.

I am trying to use the NumericStepper component in Flex and would like to give its textField (not just the whole thing) an id but not sure how. I have already given an id to the NumericStepper itself but would like to give an id to its textInput field.

I am using the following .as file as the component for an itemrenderer in a list. Basically each item is rendered in a TextInput and each TextInput has a remove button as you can see from the code. When clicking the remove button, I want to remove the selectedItem..so I am putting the function removeItem() in MainMxml.xml and calling it from the .as file.
However I am getting an error "Cannot access a method or property of a null object reference".
The .as file as follows:
package components {
import flash.events.Event;
import flash.events.MouseEvent;

I've written a little video game in Flex that runs in a browser. The player moves by pushing the arrow buttons on the keyboard, so I need to capture those keystrokes. In fact, the game action starts when the player presses one of those keys.In order to capture the keystrokes, the Flash/Flex application, not just the browser, needs to have the focus.How can I ensure that the application has the focus? I've implemented a bit of a hack: A "Begin" button you must click to start the game. The only point of this button is to ensure that the app has the focus.

I get the following warning when I run my application:
warning: incompatible embedded font 'Arial' specified for spark.components::Label (Label104).This component requires that the embedded font be declared with embedAsCff=true.
The application I am working on is a mix of Halo and Sparks components as I am migrating it to Flex 4. The text that is showing in the text fields is defaulting the systems serif font. There are a few problems with this warning.
1) I am not embedding any fonts in the application. I am not even assigning the Arial font to any of the components.
2) If I check the "Use Flash Text Engine in MX components", then all the text fields in the app throw the warning. Not just the sparks text fields.
Why does flex 4 think that I am using an embedded font with the sparks components? Is there any way to get around this warning and have the text fields use a non embedded font?

I'm trying to get the depths of all the blocks to be at the correct levels at the correct times so that the 3d effect is maintained. I've tried many things, but have had little success. All the instances of the blocks are stored in an array, but since it's adding them in accordance with when they're added to the stage, it doesn't help me locate them to swap depths. Is there a way to arrange them by location on the board?

I think this is just a matter of fine tuning some different elements, but I'd like to know your take. I've got a Flex app, using the Flex 4 data services, communicating with Zend AMF services. One of the services returns all the results in a database using SELECT * FROM table there are ~1200 rows (140KB package size).
My problem is the response time, it's rage inducing. Total duration is always between 7-8 seconds. All but about 150ms of that is latency. I broke up the PHP to figure out exactly where the latency was and turns out return $rows is eating up ~6.8sec latency. I can deal with 1-2sec, but when I start waiting around for 8sec I feel kinda dumb. I cross checked the query response speed directly from the database, and just like I was expecting the total query time is 45-60ms.
PHP, this is basically just the generated Flex data service code, although in production it isn't the same:
public function getAllProject_entries() {
$stmt = mysqli_prepare($this->connection, "SELECT u.*
FROM $this->tablename u");

I've created a search with a couple of comboboxes that allow users to filter their search results. The results are currently using a TileList & itemRenderer to display, and now I'd like to add an animation effect when the user filters their results. I know that you can use the itemsChangeEffect to create an animation effect when the user drags and moves result itmes. So I'd like to know if there's a way to create a similar effect triggered by the filtering on the comboboxes?

I have a table in the database:
name Opinion
Tim Tim has an opinion
John other random text
Dan Dan's random text
Al Al says something else
I call this data and get it back in
getRecords.lastResult
To access John's opinion, I could use:
getRecords.lastResult[1].opinion
But that's only because I know that John is the second record (record 1), but this may change. So the right way is to search through the results to first find the record index for John, then access his opinion.
I need some sort of a loop? Is there an easier way to search for John directly without a loop?

I've got a suite of unit tests for my project (pure AS3), and they all work brilliantly outputting standard JUnit XML to the trace output window. However, when I tried to get my test suite running on our continuous integration server I ran up against a wall.Flash is a sandboxed beast, isolated from the file system. I can't see an intuitive way to get this generated JUnit XML in to our CI software so it can be verified as passing.
I've taken a shot at implementing the approach shown in Continuous Integration with Flex,but it relies on reading trace output logged to flashlog.txt that is prone to failure on many fronts (debug player must be installed, flashlog.txt must be created, mm.cfg file must be configured properly). Also, I find that some of the time it fails to find the results in the flashlog and the build fails despite all the tests passing. This could be because I have too many tests and some are being pushed out of the log file.

I've got a simple app that is currently getting information form a database and just displaying the content into a datagrid.
Instead of having this information displayed in a datagrid, I'd like to display it in a couple of labels (first name, last name, phone, etc.), but I'm not really sure how to.
Currently on creationComplete I call my php query function - which looks like this.
public function getPeople() {
return mysql_query("SELECT * FROM tbl_people ORDER BY pers_name ASC");
}
[Code].....
Eventually my query will be modified and will only ever return 1 row from the database. So how do I get the results to display in labels instead of the datagrid?

I am trying to load an image in Flex (AS3) which already exists:
<mx:Image id="Img"/>
With this code:
Img.load('[URL]');
The path is verified to work, but I always get this error:

I used the code from the documentation and still receive this error!

I guess the best way to explain my issue is to describe it in terms of the hierarchical XML data example on Livedocs.
Here, the XML is of the form

I am trying to overlay a label onto an AdvancedDataGrid when there are no results returned from a call for the data. Here is a mockup of what I am trying to accomplish [URL]. I tried following this previous answer: Drawing an overlay in custom flex component, but this would not work for me because an AdvancedDataGrid is not a Container (and as such does not have a rawChildren property). I would prefer not to need to mess with the data provider, because this table will be used in many location which will have different columns and labelFields.

I'm using Flex 4.5 with PHP Zend webservice framework. Basically, I have 2 DataGrids that can drag and drop between each other. At the initializing of the component, I call a webservice to populate the top DataGrid. Then the user can drag rows to the bottom DataGrid that get processed and saved later on. My problem is that I want to have a reset button (or cancel button), that will take the user to a new component in the ViewStack, and if they return to the component with the DataGrids, the top DataGrid has the original records and the bottom DataGrid is empty.
I just can't figure out a good way to repopulate the top DataGrid. I can clear it, but it doesn't seem to refresh with the original data. I've tried unsuccessfully to call the webservice again and set the dataprovider to the new lastResult token. I've also tried unsuccessfully to copy the results of the initial webservice call to an ArrayCollection and simply set a Bindable variable to that ArrayCollection (or a backup of that ArrayCollection holding original records).

End-User searches for something and an ArrayCollection is returned with Result objects. This is displayed in a data grid.End-User selects a few of the search results and "moves" it over to another datagrid for use later.End-User does another search.
PROBLEM:Some of the search results might contain something the user already previously selected and moved over to the second datagrid. I want to remove these from the second search result.

I have been making huge strides in learning Flex and I am very much enjoying it, however,one thing I cannot find is how to bind results from a query in Flex. I have managed to create lists etc no problem but when I try to bind one specific value to a variable, it does not work.First off, here is my PHP function:
public function getRepnameByUsername($itemID) {
$stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename where Username=?");

When I test my deployed app in a browser the popup window continues to be displayed even after it should be closed. Everything works as expected when debugged in Flash Builder 4.
Following is currently what's happening: the request is sent to my restful web service, which processes the request, (seemingly) the ResultEvent is called which in turn dispatches the profileEvt dynamic event that changes the view state. However, the popup window does not get closed and the applet gets 'stuck.'
Below are the flex applet web service event listeners/handlers:
webService.addEventListener(ResultEvent.RESULT, function(event:ResultEvent):void
{
var rawData:String = String(event.result);
var profileEvt:DynamicEvent = new DynamicEvent("profileSaved", true);

I am creating a Flex3 app to return some results from the Google Geocoding API. I am using the HTTPService Events sample from TourDeFlex as a reference guide to mimic. For now, I have hardcoded the response from Google to use this XML response: [URL] Network Monitor suggests that I am getting a valid response from the XML, but I imagine I have not referenced it correctly for populating my DataGrid?

I have an AdvancedDataGrid with a custom label function whose value can change based on other form status (specifically, there's a drop down to choose the time display format for some columns).Right now, I have this labelFunction:
internal function formatColumnTime(item: Object, column: AdvancedDataGridColumn): String {
var seconds: Number = item[column.dataField];
return timeFormat.selectedItem.labelFunction(seconds);
}
[code]....
... and the timeFormat object is a combo box with items whose labelFunction attributes are formatTimeAsFractions and formatTimeAsInterval.The columns that have time formats have formatColumnTime as their labelFunction value, because extracting the seconds in that function and passing it in to the formatters made for a more testable app (IMHO).
when the timeFormat.selectedItem value changes, I want to force my grid to re-calculate the labels of these colums. What method must I call on it? invalidateProperties() didn't work, so that's out.

Sometimes while typing in a textarea in Flex many characters will be rendered at one height then at some point on that same text line the rest of the characters are rendered a couple pixels lower than the rest. Here is an example, look at the last 'I' character, its low:
Sometimes changing the font size will fix this but its not consistent and its not something I can detect (and fix even if I could). Anybody got an idea why this happens? It happens for embedded and non-embedded fonts.
