ActionScript 3.0 :: Safely Switching Focus During Backspace Key Down Event?
Sep 1, 2008
I have a simple form that I'm building. It has a variable length list of entries, and I'm using a TextInput for each entry.
Because the list is variable in length, I'm allowing the user to delete elements from the list. One of the ways they can do this is to press the backspace key when the cursor is in an empty TextInput. I am handing KeyboardEvent.KEY_DOWN and checking for the backspace key, to accomplish this.
The problem I am having is that after I remove the deleted TextInput, I want to leave the focus in the TextInput above. I can do this using 'setFocus', and that works fine, however it seems that the backspace is still processing, and so after the focus is set, the content of the TextInput is delete which I don't want.
To get around this, I've created a one-shot timer with a 0ms delay which changes the focus after the KeyDown event has completed.
My workaround is successful, but feels very heavy handed. Is there a better way to achieve the same effect?

If I have a prompt window where I am asking the user for some input, is there some way I can prevent them from switching window focus to the other windows in my application? (switching to other applications is fine) I'd actually have preferred if the window didn't appear in the taskbar at all, but utility windows look awful and I'm using system chrome so lightweight is out.

I have a mouse trailer that lets the user smear paint splats over the stage area. The trailer works fine stand alone, but when I attach a listener to give the user the option to turn the trailer on/off via a pair of buttons, the trailer turns on/off but now fails to follow the mouse cursor!
Here's the trailer code... (I've attached the CS3 file just in case)
Code:
i = 0;
onMouseMove = function() {
var cur_x = _xmouse;

Is there a 'onFocus' event for individual radio buttons, or is it limited to the radiobutton group ?If there is a focus event for the buttons, how to I set it up ? I've set up an event listener with an 'onFocus' event, 'gotFocus' event, 'focus' event and nothing is triggered...

I'm having an issue where I don't get a "FOCUS_OUT" event called when I click around the stage. I do get the "FOCUS_IN" event when I click the TLFTextField.Here is some of the code I have:
txt_search.addEventListener(FocusEvent.FOCUS_IN, onFocusIn);
txt_search.addEventListener(FocusEvent.FOCUS_OUT, onFocusOut);
private function onFocusOut(e:FocusEvent):void[code]...

Is it possible to override the default focus event on the in-built TextField class? So for example when a textfield gains focus a custom event is triggered rather than the default one? I know we can use the onSetFocus event, however we have over 1200 swfs that use TextFields so want to do it on a global scope rather than having to modify each individual swf. that on an Android tablet selecting a TextField brings up the android keyboard that not only shrinks the flash content, but defaults to the alpha keyboard when all we want is numeric (it's a Maths app).

I'm trying to add a focus event to a text box. For some reason the Focus_in works fine, but when I go to add the focus_out event it tells me that the name I am trying to assign to the listener is an undefined property???? of course it is I just created it and the one I created just before this for the same text box works just fine. here is the code: midTermGrade_txt.addEventListener(FocusEvent.FOCUS_IN, onFocusBevel);midTermGrade_txt.addEventListener(FocusEvent.FOCUS_OUT, offfocusbevel);As stated alread the first line of code works perfectly

I have a custom TitleWindow component that is registered to listen for keyboard events from the user (so that esc closes the window, enter saves, etc.). However, in my testing I've found a couple cases where my keyboard event handlers don't fire. My best guess as to why this is happening is that there is some child component somewhere that has stolen focus and is stopping the keyboard events from propagating.
Unfortunately, due to the large number of components in my TitleWindow, I have no good way of knowing who has stolen the focus. My question then is, are there any good tips / techniques / tools for debugging focus issues and event propagation in Flex? Basically, I need something that will tell me who has the focus at any given time and who's handling an event at any given time... is that possible?

My Sprite class keeps losing focus when I click with the mouse - specifically after the MOUSE_DOWN event (before the click is complete).
I have set mouseEnabled to false on the children, no change. I added a listener for FOCUS_OUT and noticed that the FocusEvent.relatedObject property is NULL, which is confusing me - doesn't that mean there is no new focus target, the focus is just getting lost?
The exact sequence of events I get, by tracing them, as I click:
[FocusEvent type="focusOut" bubbles=true cancelable=false eventPhase=2 relatedObject=null shiftKey=false keyCode=0]
[MouseEvent type="mouseDown" bubbles=true cancelable=false eventPhase=2 localX=355

I need to return to my original function after capturing an event (downloading something) with another function. The original function needs to return a value, which depends on the downloaded data. So, I'd like to pause original function for the time needed for the download and the eventhandler function to complete it's work, and resume it afterwards.
The obvious way is to set a flag value (both the original function and the eventhandler are within the same class) and make the original function check it until the eventhandler function changes the flag. But that would be wasteful, and my AS is slow enough already:) [other parts of the application utilise some heavy graphics]. Is there another way? Like an event that gets captured "in the middle" of the function? Or some other form of flow control?

How would you make a button event call a function which acts like a backspace keyboard event delete.I tried faking the dispatch keyboard event "keyup" "keydown" with keycode 8 and keynumber 8 without success.No other way than doing it by hand with begin and end select index plus substr ?I have a textinput i just want to add a button acting like a backspace.

I have noticed this bug when developing my flash application on a windows platform. If typing text in to a text box in a Flash swf running in Safari 5 browser on Windows then press backspace the browser will jump to the previous page in history rather than performing the function that backspace is supposed to - here is a link to another report of this apple bug.URL...

I have got everything working on a virtual keyboard, except the backspace button. Does anybody know of a method that uses the .appendTest() to delete the last character typed by a user???
Inputtext field is named "dirsearch"'
_del is the instance name of the button that hopefully act as a back space button.
my code so far:
_del.addEventListener(MouseEvent.CLICK, deletelast);
function deletelast(e:MouseEvent):void{[code]..

I am implementing a flex auto-suggest combobox - as the user types in each character: Consider the string 'Stackoverflow' and user input = 'st'
1) the data provider is filtered to show all items starting with 'st'
2) text is set to auto-suggest string such that the un-typed part is highlighted.
So for instance, the combobox text may contain st'ackoverflow', where 'ackoverflow' is highlighted using setSelectedIndex()When I hit back-space or delete, and check the 'this.text' value, I expect that the last un-highlighted character ('t' in the above case) gets deleted and the data provider is filtered to show all items starting with 's'. However the text property contains 'st', as before
