Help with Button actionlistener

Hi friends , I have simple question but i am not getting any idea how to solve this..
I want to call a method in one class from other class...ie
I have a class called checklistmod which contains method called onClickDeleteButton(CheckInfoItem checkInfoItem) where Checkinfoitem is another help class in the same checklistmod class.
I have another class called showlist which contains a button called "Delete".
my question is i want to add a actionlistenet for "Delete" button such that when i click the "Delete" button it should call the method onclickDeleteButton(CheckInfoItem checkinfoitem) method in checklistmod class..
Does anyone has an idea
sorry if my question in not clear..
Thanks in advance

So call it. These are just classes and methods. They should be treated like any other classes and methods. Of course since (I assume) onClikcDeleteButton is an instance method (not static) the class showlist will have to have access to (a reference to) an instance of the class checklistmod.
Also, the class CheckInfoItem has to be public so that showlist can create an instance of it to pass to the method.
One general technique would be for checklistmod to register itself to be called when the delete is pressed.

Help with buttons :S

hi all,
i'm new to flash but i have an idea whats going on with webpages. I need some help with buttons! i have a website and its has a stage and 9 different flv's (screens). I've been trying to read online and i can't find out how to navigate to different screens, example below
home          |            |
about us     | stage   |
contact       |            |
you click one one button it updates the stage. also i'm using actionscript 2.0.
thanks for any help ahead of time
Thank you,

Is it a wi-fi or cellular connection that isn't working? If its wi-fi and other people/computers/phones can connect check your settings. If its cellular, are other people's phones (on the same carrier) working in the same location? If other people can't connect then it is likely a network problem. If others can you may need to reset/restore you iPhone.

Help with button code please?

I am a novice and have just completed my first animated movie. I need help with action script.
The movie is currently looped and I have created and invisible button the size of the frame with the intention that a user can click on the movie image to stop it and on second click continue the movie from where it stopped.
I have used the AS event handler method to stop the movie. I have tested it and it works. But I cannot figure suitable code to restart the movie.
Two questions;
1. am I going about the task the right way? (should I use two buttons, one stop, one start)?
2. if my approach is feasible, can anyone give me the correct AS to re-start the movie and put me out of my misery please?

you can use the following after changing "yourbutton" and "yourmovieclip" to use suitable instance names:
yourbutton.onRelease=function(){
if(!this.toggle){
yourmovieclip.stop();
} else {
yourmovieclip.play();
this.toggle=!this.toggle;

Here is what I am doing. I am creating an "operations"
calendar for my workplace. So far I have been successful with

- People about these parts comment on Java problems, not Netbeans problems. Netbeans has its own [forums for Netbeans problems|http://forums.netbeans.org/] (<- link), try them.
- As far as the Java code goes, you will get a much better chance of help if you..
a) Post an SSCCE (<- link), rather than random code snippets that you think encapsulate the problem. Let's face it, you don't know the answer, and until you do, you cannot be sure the fix is to be found in the code snippets you post. Can you?
b) Post code in between code tags to retain the formatting and indentation. To do that, select the code and click the CODE button on the Plain Text tab of the message posting form.Easy there tiger, this is not a netbeans problem, so he is in the right place.
The code does look to be SSCCE or close anyways (remove the ... lines and if it still compiles and run I would say this is SSCCE).
The code tags is a huge problem here though. I am trying to read it without getting a headache, best as I can tell the OP seems to be doing some really funny stuff with paint. Like is he overriding paint to paint a square? That can't be good!

Help with buttons in photo gallery

Hello all
I am trying to find a more effeicent way to place buttons on each of my pages (Photo Gallery SIte). I have 150 pages and constantly have to link each button to the "next" or "last" button. Is there a more efficent way to for me to ad butons to each page.My site is Blazinginterest.com
Please give me some feedback on my site, possibly add a picture viewer?
Thank you, HD

what code do you already have? Maybe we can help you modify
it where it's not working.
Also, how do you have it currently laid out? eg. do you have
several images on the screen, but some method to scroll through
other images? Have you done a search here or on director-online.com
(in the forum or articles section) on similar questions? Do you
have something written up to describe what features you need such
as a design document?
Just trying to get a sense of your level of programming in
general, experience with Director and what planning/details you
have worked out so far because there are so many different ways to
program a gallery.

When I try to make a simple applet with just one button showing, then it works perfect...but when I make the applet a little bigger with some graphcis and text, the setLocation() and setSize() methods don't work. the wierd part is that I don't get an error message, the compiler just ignores those lines...so it seems anyway.
If anyone can help me I'd be very greatful
thanx a lot

Do you know there are 5 layout managers in java. It is probably worth looking through each one and the commands they use.
The layout is determined by two things:
1.position Components are added
2.Layout manager used
Ive never had to use setLocation() and setSize() as the layouts do it for you:
1.Flowlayout: which is the default pane. e.g.
setLayout(new Flowlayout()).
2.GridLayout: postions panels into rows and columns
b.GridBagLayout
3.Borderlayout(NORTH,SOUTH,EAST,WEST and CENTER) postions in applet.
4.CardLayout(a bit like a slideshow)
5.Insets() which is used to determine top,bottom,left and right.
Don't bother about 4 or 5 yet. But definitly have a look at the other 3.
e.g. setLayout(new BorderLayout());
add("North", new Button("ok"));
add("CENTER", new Button("Exit");
etc..

Need help with buttons in a phone simulation

Hello
I have built a telephone interface to be used for training in a Call Center.
I am attempting to allow the user to press on the numberpad to enter passwords and such.
It is only a simulation and will only work if the user presses the correct buttons.
I am able to create the simulation when the user presses different buttons such as 1234
but I need them to press 0000 (zero 4 times)
I am not sure how to do this...
I have been playing around with the advanced actions, which has allowed me to accomplish the hide and show actions when the user clicks a button, but wondering if there is a way I can
have them click the 0 on the dialpad so each time it brings up the next zero
once its gets to the 4th one, it will advance to the next slide...
Hope that makes sense
I appreciate any help or advice
thanks
Melissa

Hi there,
What I did, I took a variable 'counter123' and assign '0' value to this variable.
I then added a button with Advanced action, I am sharing the Screenshot of the advanced action panel.
Screen shot 1 :
Incrementing the Value on click :
The value of the variable should increase on every click, so lets add a true statement as a condition.
Screenshot no 2 :
As normally on buttons/click boxes, the project will continue as soon we click them.
lets compare the value of our variable and then pause the project.
Screen shot 3 :
last if our purpose is solved, here we have clicked the button 4 times, so that has updated the value of our counter to 4, so as soon as the counter exceeds the value, we want the project to continue.
please let me know if this helps you.
This will help you in pressing a button 4 times, and i think you can also add actions to show and hide 'zeros' in your project.
I find such scenarios very interesting and I always find help on Lilybiri's Blog : http://lilybiri.posterous.com/
Thanks

NEED HELP WITH BUTTONS IN AS3!!

Hello, I am stumped with an action scripting problem. I'm
trying to create a really basic website in flash using buttons to
jump from scene to scene. Let's say I want to do something as
simple as make scene 1 jump to scene two right? I'll place in my
scene 2 button on my first page:
But instead of the scene changing to the next scene after I
press the button, these errors come up!!
1180: Call to a possibly undefined method on.
1120: Access of undefined property release.
1120: Access of undefined property _root.
I've tried asking in so many different forums, I usually do
pretty good with action scripting for buttons. But this is my first
time doing it with cs3. I'm utterly confused, someone please help!!
Thank you.
The code on this page is the code I was using to try to
change scenes...Oh! and whenever I try to put a code in the actual
button, it won't let me. I just get a message that says something
like "Can't have any actions applied to it".

You're using three terms that aren't supported in
ActionScript 3.0: the
on() function, the release parameter to that function, and
_root. In
ActionScript 3.0, you'll have to give your button an instance
name and wire
it up like this:
http://www.quip.net/blog/2007/flash/making-buttons-work-in-flash-cs3
In that blog entry, you'll see (with explanation) something
that looks
like this:
myButton.addEventListener(
MouseEvent.CLICK,
function(evt:MouseEvent):void {
trace("I've been clicked!");
Just bear in mind that you can also make that a named
function, like
this:
myButton.addEventListener(MouseEvent.CLICK, clickHandler);
function clickHandler(evt:MouseEvent):void {
trace("I've been clicked!");

Your issue isn't Flash CS3, it's that your FLA file is
configured for
ActionScript 3.0. If you change that to AS2, you can go right
on using the
same approach you used to -- and you'll be able to attach
code directly to
objects. ;)

Help with buttons in AS3

Hi Folks,
I'm stuck with a simple flash movie I need to create in which two images fade in and fade out, and each of them must be clickable and hyperlink to a separate URL.
I've got the fading going okay, but I cannot for the life of me get even a single button to work on it.
If it's helpful I can send along what I've got so far. Any assistance would be greatly appreciated.
Regards,
Andrew.

Hi Ned,
Thank you for the followup email.
I think I was close - I was aware of the changes between AS2 and AS3, but I
think I was putting the Action in the wrong place.
Next question - if I have 2 buttons (say btn1 and btn2), how do I make btn1
available for say frames 1-60, and btn2 available from frames 61-120?
I am primarily a ColdFusion developer, and a complete newbie to flash, so
sorry if this is a dumb question.
Regards,
Andrew.

In AS3, to make a button work with code, you need to add an event listener
for it. In the timeline that holds that button, in a separate actions layer
that you create, in a frame numbered the same as where that button exists,
you would add the event listener:
>
btn1.addEventListener(MouseEvent.CLICK, btn1Click);
>
Descriptively, that line of code contains the following:
>
buttonInstanceName . displayObjectMethod (eventClass . eventType,
eventHandlerFunction);
>
The name of the function for processing the clicking of that button was
already defined at the end of the event listener assignment, so now you just
have to write that function out:
>
function btn1Click(evt:MouseEvent):void {
   var /String = "http://www.awebsite.com/awebpage.html";
   var req:URLRequest = new URLRequest(url);
   navigateToURL(req);

Help with Buttons in Actionscript 2

Help!! I am creating a Flash movie with 5 scenes. I have
buttons for each that I have added actionscript to, but they still
do not work. I am not getting any error messages. I am using
actionscript 2 and have gone step by step. here is what i have :
on (release) {
gotoAndStop("main", 1);
on (release) {
gotoAndStop("blackboard", 1);
etc for the rest of the buttons. Any help would save me much
stress as I am trying to finish a project for school!!! thanks
ah

Try adding _root. before the gotoAndStop command. If you have
the code on the buttons that is.

Help with buttons in gui

I need to create first, last, next, and previous buttons in my gui. I have them in there (in the code), but only one button shows up (instead of four), and it has "first" overlapped with the "previous" button. The "next" and "last" don't even show up at all.
Can some one guide me please? Can someone tell me what I am doing wrong?? Thank you in advance

Help with Buttons on MIDlet application

Hi,
I'm writing a game on MIDP using Netbeans' cellular simulator.
How can I make buttons on the screen? those buttons should have the ability for the user click on them & then
the screen would be change (using by ActionListener).I know that on GUI I should write it as many JButtons in the place
where the game board should be at, but what should be written when using MIDP and how to connect to it a "Listener"?

Hi,
the philosophy used for application design and development on mobile devices differes from desktop design and development. And using the Java ME has some specifics and limitations. You have basicly 3 options to develop your applications:
1) use high level API screens - List/Form - in this case the application will look differently on every device and usually not too good and you can't control formatting of the output, but the development is very fast and easy
2) use existing graphical libraries - like LWUIT - good choice for many applications (but games), gives you rich API (in relation to the native List/Form) with good results - it's only slightly more complicated and the result is significantly better
3) build your own UI on Canvas - you can display whatever you want... but you must fully implement it
Every next option needs more effort but gives you more freedom in application design and development.
I know that I didin't answer exactly what you asked for, but I'm sure that this answer makes more sense...

Help with buttons/actionscript

I've got a movieclip acting as a button. Code on the button itself handles roll-over/-out states, and I define an onRelease function in the main timeline as follows:
backBut.onRelease=function(){
gotoAndPlay(1);
This code takes the movie back to the first frame and works on the third frame. For some reason, though, the same code on the fifth frame has no effect. The button doesn't do anything. I have tried using the same button, I tried inserting a new keyframe with a new button, renaming the button, etc. and for some reason I just can't get it to work on the fifth frame.
If it helps to visualize, I am essentially making a menu. The first frame contains buttons to take you to submenus, located on following slides. This button to go back to the original menu is on each frame with a submenu, but for some reason only works on one of them. Thanks in advance for your help.

Try moving that button in frame 5 to it's own layer. If it's the same llibrary symbol, what happens is the name from the preceding instance gets inherited, along with other characteristics. If frame 4 doesn't do anything, instead of a new layer, just try putting a blank keyframe between the buttons in frames 3 and 5. This may not be the problem at all, but it's my first guess at the possible problem.
