Why??? Definition 1172: Definition fl events.ComponentEvent could not be found.

[alexr58234163]

I am trying to ask for input in an input textfield and the way Im doing it is using

import fl.events.ComponentEvent;
input_text.addEventListener(ComponentEvent.ENTER, readInput);
input_text.addEventListener(Event.CHANGE, changeHandler);

var clearing:Boolean=false;

function readInput(event:Event):void
{
    input = input_txt.text;
    trace(input);

    clearing=true;

}

function changeHandler(event:Event)
{
if(clearing)
{
  input_text.text="";
  clearing=false;
}
}

in my code, however am getting a Definition 1172:  Definition fl events.ComponentEvent could not be found.

I am only doing all of this junk instead of a simple input_text="" on a keycode=13 event listener; because when i do that it adds a blank return line "

 "to the input when they hit enter and I dont want that. They told me i could do this and it would solve the blank extra return line problem (when i ask a person hit enter to submit the text) but they didnt mention that there would be this error. What do i do

i don't see why you'd get that error though you have two other obvious errors:

input is undefined

input_txt is not input_text

[alexr58234163]

kglad, when I begin to type import, then type  fl.events. i can see a list of all the available packages, component event isn't there! Neither when using flash.events.

[kglad]

copy and paste here a screenshot of your stage with the textinput component selected also showing the properties panel.

[alexr58234163]

[kglad]

that's not an input text component.  it's just an input textfield.

either adjust your code and remove that textfield and replace with a textinput  component.

[alexr58234163]

wowwwwwwwwwww i have never heard of that.  i dont know how to add one

[kglad]

open your component panel (window > components) and drag a textinput component to the stage.

though it would be better (imo) to continue with an input textfield and fix your code.

[alexr58234163]

Help me please. This is confusing. I would like to just use input textfield that I originally planned. My problem is that when pressing enter,  the string returned adds the unncessary blank line " ". how do I prevent the addition of a break line when the user presses enter?

[kglad]

do you want to use a component (less flexibility but some additional styling) or an input textfield (which you're now using and has less styling but needs different code)?

[alexr58234163]

Hehe I would like to know how to do it with input textfield. Do you want a video of me show you what i mean or do you think you know what i mean? Ok obviously they type a little, press enter, the text box should empty and what they type should occupy in the first space directly above. However what ends up occupying is 

"

"

or 

"

the text"

[kglad]

if your textfield is ti, use:

//////////////////////////////////

ti.addEventListener(Event.CHANGE, readInput);

ti.text = "";

function readInput(e:Event):void {

trace(e.currentTarget.text);

/////////////////////////////////

then describe how you want the trace output to appear, if it's not what you want currently.

}

[alexr58234163]

OKAY. Alas, when I use the code 

usertext.addEventListener(Event.CHANGE, readInput);
usertext.text = "";

function readInput(e:Event):void
{
if (e.keyCode==13) //enter
{
trace ("keycode is 13");
usertext.text = "";
trace(input);
chathistoryline19.text=chathistoryline18.text;

chathistoryline18.text=chathistoryline17.text;
chathistoryline17.text=chathistoryline16.text;
chathistoryline16.text=chathistoryline15.text;
chathistoryline15.text=chathistoryline14.text;
chathistoryline14.text=chathistoryline13.text;
chathistoryline13.text=chathistoryline12.text;
chathistoryline12.text=chathistoryline11.text;
chathistoryline11.text=chathistoryline10.text;
chathistoryline10.text=chathistoryline9.text;
chathistoryline9.text=chathistoryline8.text;
chathistoryline8.text=chathistoryline7.text;
chathistoryline7.text=chathistoryline6.text;
chathistoryline6.text=chathistoryline5.text;
chathistoryline5.text=chathistoryline4.text;
chathistoryline4.text=chathistoryline3.text;
chathistoryline3.text=chathistoryline2.text;
chathistoryline2.text=chathistoryline1.text;
chathistoryline1.text=input;
}
}

it throws error Access of undefined property keyCode thru a reference with a static type  flash: events

and when i leave it as function readInput(event:Event):void and not function readInput(e:Event):void it says Access of undefined property e

[kglad]

use a keyboardevent if you want keycodes.

ti.addEventListener(KeyboardEvent.KEY_DOWN, f);

function f(e:KeyboardEvent):void{

trace(e.keyCode)

}

[alexr58234163]

Okay. Sgh. Now we are back to where we started. Where it enters a blank line and it copies the text to the text history with a blank line above it. I'm trying to avoid that. I want to let them write a line of text and when they hit enter is when i want the text in the text box to move to the text history fields. 

[alexr58234163]

this code is not effective

addEventListener(KeyboardEvent.KEY_DOWN, readInput);
usertext.text = "";

function readInput(e:KeyboardEvent):void
{
if (e.keyCode==13) //enter
{
trace ("keycode is 13");
usertext.text = "";
trace(input);
chathistoryline19.text=chathistoryline18.text;
chathistoryline18.text=chathistoryline17.text;
chathistoryline17.text=chathistoryline16.text;
chathistoryline16.text=chathistoryline15.text;
chathistoryline15.text=chathistoryline14.text;

[kglad]

if you want to remove line breaks from a string use string.split("\r").join("").split("\n").join("")

ti.addEventListener(KeyboardEvent.KEY_DOWN, f);

function f(e:KeyboardEvent):void{

if(e.keyCode==13){

saveTextF();

}

}

function saveTextF():void{

// do whatever you like with (ti.text.split("\r").join("").split("\n").join("");

}

[kglad]

what's that trying to show and how's that related to the code suggested?

[alexr58234163]

What this is showing is how it is adding a line and coming to be a blank line above every line the user enters. I dont know how to prevent the blank line. Its supposed to be just singlelines of entries

[kglad]

i infer that you want users to input text and then you want to do something with that text, but what exactly are you tryig to do?

[alexr58234163]

im going to tajke their answer and comapre it to some other variables to see whether it is 'correct' or not and push it up one line into histry

[kglad]

do you know how determine if their input text is "correct"?

do you know how to "push it up one line into histry"?

if either answer is no, th info you've given is insufficient to help you encode correctly.  ie, explain more carefully.

[alexr58234163]

Heh heh, yes. Later on I will have arrays wth correct responses and be implementing further code to determine whether the code matches is correct. The problem here and today is about getting that little blank line to stop injecting everywhere once they hit enter. Also, the code to push the line of text into history is already functional in the youtube video shown previosuly

[kglad]

i already showed you how to do that using split.join
