Flex :: How To Programmatically Enlarge Buttons HitArea
Aug 13, 2010
How to programmatically enlarge a flex 3 button's hitArea. Is there some function that I can override? There is no function in the button class called hitArea. What I have done is, I have created a programmaticskin for a button. The form of the skin consists out four arrows. In between the arrows there is nothing (meaning transparent). Because of the way the skin is shaped, it's difficult to click on the button. The skin has alter the buttons hitArea. What I'm looking for is a way to enlarge the hitArea and alter the hitArea shape in to an square. (the hit area must ofcourse still be invisible).

Is it possible? What I'm trying to do is enlarge the hitArea for a selected movieclip on my stage, but only onRollover. I have 5 MCs on my stage acting as buttons of sorts. onRollover of any of the clips, they grow in scale and I'd like the hitArea to do the same so they (MC and hitArea) are proportional.

I am making some buttons that enlarge and then fall back to their original size when you mouse over them. The font used is a pixel font and this blurs when you do the mouse over. Is there anyway you can make them so they dont blur?
This is the code on the movie clips:
onClipEvent (load) {
xlen = 100;
ylen = 100;
xscale = _xscale;
yscale = _yscale;
[Code] .....

I know this should be do-able, but i am stumped... I created a row of movie clip buttons + eventListeners (CLICK) with a for-loop. i now want to take an array that consists of a list of swfs (i.e., var myArray:Array=new Array(); myArray=["thing.swf","dog.swf",more.swf",etc}--and programmatically assign a loader + URL request to each of the created movie clip buttons that will load the swfs on the button click.

I have a spark skinnable component which contains a datagroup with images. The datagroup is scrolled by hovering the mouse over it. Everything works fine except one thing: after I change the datagroup provider, I need to scroll down automatically. The problem is the images are not loaded immediately after I set the provider so (contentHeight - height) does not yet represent the actual maximum scrolling position. Is there an easy way of telling the datagroup to scroll down as its content loads? Because the workaround seems to be not so straightforward. This is the code for scrolling(thumbnailStrip is my datagroup):

I'm using a dateField component (with editable = true) as an itemEditor in a dataGrid. Interestingly, when editing the textInput part of the dateField it doesn't seem to react to an ESC keydown as I would expect, i.e. reload old dateField value and give up focus. This seems to be standard for most other components, but not for as most other components do.
How would you go about implementing such behavior? I can listen to keydown == escape on the TextInput portion, but just realized that I don't know how to tell dateField to give up focus and politely close - in fact I'm not even sure that's the right strategy (maybe I should work at the DataGrid level?

I need to load several images as Bitmap or BitmapData objects. The images are hosted outside the Flex project, and they're referenced by an external configuration file, so I can't embed them. Because the images won't be displayed directly to the user (they're being added to a PDF that is generated for download), creating a grouping of Image objects, attaching them to the application, and waiting for their LoadComplete handler to fire seems inefficient.
What is the best way to load these images into an application? Programatically load images in it?

I would like to know the correct way to close an AIR application programmatically. In my Spark WindowedApplication I have:this.addEventListener( Event.CLOSING, shutdownApp );and of course an implementation of the shutdownApp method (which basically tidies up temporary files).his works fine for the top-right close button of the window. However I also have functionality which needs to shutdown the application. Within the code I have called:NativeApplication.nativeApplication.exit();However this doesn't trigger the Event.CLOSING method, and so my temporary files are not cleared up. Should I not be calling nativeApplication.exit ? If so, what should I call instead? I'd rather not have to call my shutdownApp method before the NativeApplication.exit() as this doesn't feel quite so elegant.

I have various components that are skinned through a programmatic skin. The skin class references a singleton class that holds various colors to be applied to different aspects of the component. The singleton class has default colors set to variations of black/grey etc. I'm loading in custom colors from an XML file that are then loaded into the singleton. I'm applying the custom skin through a css stylesheet that is included in the main Application mxml.
The problem is that when the swf initially loads, the components that are drawn on screen are black and don't reflect the changes in color loaded from the XML file. I have some dropdown windows that show on button clicks and those dropdowns do reflect the correct colors from the XML file. Therefore, the system is working correctly, but the initial drawing of components obviously happens before the XML is loaded and applied to the singleton.
My question is, is there a way to apply a skin to an element programmatically by calling the constructor?
I have this in my css file:
.PanControlsBackground {
borderSkin:ClassReference('skins.buttons.PanControlsBackground');
}
[Code]....
or something to that effect? This way, I can remove the loading of the skins in the css file and control when they are instantiated to ensure that the correct colors are applied before displaying the various components.

If I create a Movie Clip and assign a child Movie Clip as the hit area using this.hitArea = this.mcClipName; is there a way for me to disable that hit area? For instance, mcButton is a button. When I click mcButton, it triggers a function that reveals other content in my movie. I don't want them to be able to click that button again unless they close the new content (using another button that appears with the new content).

is there a way to assign a dynamically created movie clip the hitarea of a PNG file that is loaded into it via actionscript, basically creating a none square/circle hitarea that is a mask of the bitmap image.

In Flex you can stream microphone audio to an FMS/Red5 server using NetStream.attachAudio, which requires a Microphone object. Is it possible to stream audio through the NetStream from somewhere other than a Microphone? For example, from a file/embedded resource?
The reason I'm asking is that I'd like to be able to run automated tests that don't require using an actual microphone.

I have a question I came up with 3 days ago about how to do the blue underlining of a datagrid row programmatically. I thought to have found the solution, with just adding the column and row Indexes to the datagrids editedItemPosition Property.It turned out, that this is just practical if you want to be able to edit the grids row right away. But what if I just want to underline it with the blue color?Additionally how to detect that a list based Item got this kind of selection? es there a event to detect that? whats the name of this kind of selection?

I created an application as part of an ASP.NET site. I would like to receive error notifications in my inbox whenever something goes wrong with that flash application.As I do not have control over our mail server (which has a different domain name), I cannot establish a cross domain policy allowing me to send error emails to my inbox.Instead, thought I'd send a request to an ASP.NET handler that sends an email on behalf of the flash app.Now the problem: the error report should include a screenshot of the flash application at the time the error occurred. The FileReference class however only allows file uploads with user interaction (browse dialog) and cannot be used programmatically to send the screenshot to my ASP.NET handler. The plain old POST back only allows files up to ~200K.

I would like to programatically fire an event on a spark checkbox. I have a tab bar which has tabs enabled according to various checkboxes. I am loading data into these tabs. Sometimes tabs 1 and 2 will be enabled. Other times tabs 2 and 3. Other times tab 4 by itself (and all the other combinations). I have tried to enable the VBox (in action script) which is in my view stack but it seems to freeze the application. The VBox enables correctly upon user input on the check box. If I set the checkbox to be selected it does not fire the event and so does not enable the tab.
Is it possible to manually fire an event in Flex. I have tried to see if I can take the checkbox and get the event and fire it. Unfortunately I can only see addEventListener, hasEventLister and removeEventListener. There is no way of getting the events that are already on the checkbox

I am trying to set up a cicular movieClip as a hitArea for another, but the circular shape is not detected rather the bounding box of the movieClip. is there any way around it? am i doing something wrong?
Code:
TurretRange_mc.hitArea = TurretActive_mc.TurretHitArea;
TurretRange_mc.hitArea (TurretActive_mc.TurretHitArea);
so far i've tried these two methods.
