Flex :: Keep Focused After 'alt' Was Pressed?
Jan 18, 2011
I was making an application with AIR+Flex.
One Feature is like: when 'alt' key is down, the mouse cursor changes to B, when 'alt' key is up, the mouse cursor restores to A.
But the problem is that everytime a release 'alt' key, the mouse cursor will change back to system default (Arrow shape), and seems like the focus is on somewhere outside the stage.
That reminds me that, when 'alt' was pressed in a ordinary window, the menuBar will be focused.
How can I stop this default behavior？
p.s. I have tried the following ways and doesn't work:
1) listen to stage's KEY_DOWN/KEY_UP event, and add 'event.stopImmediatePropagation()' in the event handlers
2) listen to stage's KEY_DOWN/KEY_UP event, and add 'event.preventDefault()' in the event handlers
3) listen to stage's KEY_DOWN/KEY_UP event, and add 'this.setFocus()' in the event handlers. And 'callLater(this.setFocus)' doesn't work too.

Well, i know, it sounds easy, but the only thing I want to do is make a textfield that's always focused. When I click next to the textfield on a picture or on the root the focus changes and that's not what I need, the textfield has to stay focused.

It is a small widget. It lives in an iframe, and because of this, this method is not working. And since the iframe is loaded from a different domain there is no way to reach the top level window object.

"With the recent new 10.3 player this should be much easier, since there are new events for this specific situation."
So, using a simple flash object, and maybe js callbacks this might be the solution, but what are theese events?

I have 3 text field and i want to change its background when it is focused and change it back to white when the focus is lost.
I tried keeping background = true and border = true, but still i can't change the background.
Also when i keep tf.backgroundColor = 0x00FF00 outside the onSetFocus method then the textfield contains that background.

I have a function on root:
_root.fadeBox_mc.onEnterFrame = function (){
if (fade){
this.nextFrame();[code]....
This causes a mc to fade in and out on rollover/rollout. But what I wanna make is a box that fades in when pressed on the button and fade out when pressed for the second time. But if I say
on (press){
_root.fade = true;
}
the mc fades in, but I cant do another on (press) to fade out. Is this too confusing?

I could get some direction on something that I have been wondering about for a while. There have several flash video players that I have seen that only start to load/play the video when the object is visible on the screen.
For instance, if I click a link to an html page with an auto playing flv on it, and then minimize the window. The video will only start to play/load once I maximize the window again.
The other instance I have seen it is with the position of the page. So if an flv is placed onto a long html page, all the way at the bottom, it will only begin to load/play once I have scrolled to make it visible.
I have done some searching but have not been able to determine what this would even be refered to as. Is it controlled by Javascript or Actionscript, or is this just a the way flash player functions?

it's possible to change the default key (space bar key) to execute the action of the focused element in the stage?If you ever worked with the Focus Manager you've possibly seen that when you press the space bar the focused item is "executed".Can you disable that "executor" or can you change the space key with the enter key?

Buttons in flex can be pressed with the space key, but a client would like to press enter instead of space. This can be achieved by programming each button, but it would be very time consuming. How to do this in the less amount of time?

I am struggling a bit with keys on the keyboards controlling a movieclip to happen.Ive got a person moving when pressing right and left, and a movieclip with three frames: First frame is a movieclip with the person standing still, looking bored. The second frame is the person moving right, and the third frame is the person moving left.This is the code that Ive inserted into the persons actions on scene1:
if (Key.isDown(Key.RIGHT)) {_x += speed;this.gotoAndStop(2);_xscale = +scale;}
if (Key.isDown(Key.LEFT)) {_x -= speed;this.gotoAndStop(3);_xscale = -scale;}
this code works alright accept that when the keys are not pressed it doesnt stand still, the legs are still moving, so I tried to include this code aswell:
if (!Key.isDown(KEY.RIGHT)) [code]....this makes the person standing still when not pressed but not moving the legs when turning right and left.

In Actionscript 3 I see that if I press the "8" key (from the numpad) I got the result of keyCode of the numpad key "8", but when I disable the "Num Lock" and press the numpad key "8", the event I receive the keyCode of the Up Arrow key...
How to difference between the keys of the numpad (with Num Lock disabled) and the original keys, such as the Arrows, End, Insert, Delete and so on?
I've tried using the keyLocation property of the event, the value of that property is 0 for the arrows and 3 for the numpad, but when the Num Lock is disabled the value for the 4, 6, 2 and 8 in the numpad are 0, so I can't difference between the numbers with numpad disabled and the Arrow keys.
Also the numLock property of the Keyboard class didn't work, because I can't know if I press the Up Arrow or the 8 whit Num Lock disabled (because they trigger the same event, or I think that)

I can't use charCode, or keyCode in KeyboardEvent to find out the character pressed, because even if I change the keyboard layout, charCode and keyCode are not change (if press the same key).So, how to find the presssed character, following to the current keyboard layout?
The charCode property is the numeric value of that key in the current character set (the default character set is UTF-8, which supports ASCII).is not correct.

We have a Flex application which goes fullscreen on startup (which is possible when it's a projector .exe). When a user presses ESC, the application exits fullscreen mode. Is there any way to prevent this? This because we want to use the ESC-key for other functionality.Normally all keyboard input is disabled in fullscreen mode, but not when we run it as a projector. I already tried capturing the FullScreenEvent.FULL_SCREEN event without luck (this event is only fired when the user selects "Full Screen" in the Adobe Flash Player or hits "CTRL + F".

I don't really know what I'm doing I'm completely gone in my own code, I think I'm going around in circles!
[Code]...
Ok let me explain what I want to do: when my movie loads I want "textfield" to be focused, so I use Selection.setFocus(textfield); Fine! But on a frame before this I have a button to enter my site! Now as soon as you click this button it changes the focus so that when I enter the frame with the textfield it is no longer focused! Make sense? Well on this frame once the textfield is focused you can enter text right away! and then I have this listener which listens to an event within the textfield! Ok now I'm even more confused then when I started explaining this! Anyway I want the textfield to be focused when you enter this frame and if the user focuses something else, well then they will have to focus the textfield themselves. Basicly I just want the the textfield to be focused on load, but the problem is my button at the start! What?

Does AS3 have a way to output the physical name of a key that has been pressed? (ie. "You pressed: Left Arrow")
The obvious solution is to convert the character code to a string, but this only works for things like the alphanumeric keys. Ctrl, Alt, etc have special cases, but this still doesn't help for things like the arrow keys or the F-keys.
Another possibly naive option is to have a Key, Value pair for all the keycodes and their names. It should be almost trivial (if tedious) to code this myself, but since AIR already has things like
KEYNAME_LEFTARROW : String = "Left"
I was wondering if this ability is already built in somewhere without having to keep my own collection of strings.
