Creating a button through a class... H E L P

Can any on ehelp me...
I need to make a class, so that i in my JSP-file can create multiple buttons with different names..
Something like this:
package form;
import java.awt.*;
import java.applet.*;
public class knap1 extends Applet
     public knap1()
          Button Knap = new Button("Knap");
          add(Knap);
I'm pretty new at this, so can any one help me...
Martin

You'r right...
The only thing i want is to have a set of different classes, that makes different form tag's by sending information to them..
fx. TextField("the_name", "size","max_length")
NumField("the_name", "size","max_length")
and so on....
Can you help from here....

Create submit button through extension

hi guys i have a requirement to create a new button on oaf page.i am extending controller and writing below code.but there is no button displaying on page.plz help me.am using jdev 9i and oracle ebs 11i.
   OASubmitButtonBean oasb= (OASubmitButtonBean)pageContext.getWebBeanFactory().createWebBean(pageContext,"BUTTON_SUBMIT");
    oasb.setID("AssetDetails");
    oasb.setUINodeName("AssetDetails");
    oasb.setEvent("AssetDetails");
    oasb.setText("AssetDetails");
    webBean.addIndexedChild(oasb);
Note:region type is defaultDobuleColumn where i am trying to add button.
Please Please help me

1)
first of all you need to find the parent bean (defaultDobuleColumn)
something like this :
parentWebBean = webBean.findChildRecursive("Name of the Parent Object");
and then parentWebBean.addIndexedChild(oasb);
2) At the same time you can add the submit button using personalization.

Need to create a button through personalization

Hi
I have an oracle seeded page where in one region i need to add a button thru personalization.I followed this steps:
1. I went that region and personalized that region.
2. Clicked on the Crete Item and selected item type as button.
3. Here what all fields need to filled in order to properly work.
I have an extended controller for aoracller seeded controller.When i press on this button the logic written in the extended controller should work.Can you please provide any solution for the same?
Thanks
Preeti

Hi Preeti,
Instead of creating button using personalization, crearte the button programatically in extended controller, and attach an event to this if it is not submit button.
In PFR you can handle this button easily, using personalization if you will create button then you have to attach an event to this extended controller and then you need to handle the event for this So I think creating button programatically is simple than attaching an event to it.

Creat New Button through Web Pl/Sql

Hi,
I have 2 Queries:
First:How i can remove the default buttons which appear on the
Form after i complete the Successful Generation of Web Pl/Sql?
Second:How i can create my own Button object and place it on
screen,bcz by default this buttons dosn't appear at all on
screen.
Thanx.
Pritam

New to Oracle and your nick says OCP? High hopes perhaps? ;-)
The answer here is pretty complex (dealing with mod_plsql document table, processing CLOBs, using options such as external tables, writing your own tokeniser and CSV parser, etc).
I'll be happy to touch on these.. but maybe you will find a lot more joy, a lot less frustration, in using APEX instead. See http://apex.oracle.com for details.

Creating a Button Class from MC

I have a few simple questions for those who know about
classes. I have been reading the tutorials on creating classes and
specifically extending the MC class. I am pretty sure that an
extended MC_Class might help me get what I need from my project.
I essentially have a bunch of buttons, hundreds to be exact -
and the exact number needs to be dynamic. Each one is currently a
static MC with a bunch of variables assigned to each one via global
variables. Its iis pulling in data taht assign the button values
from XML files and - these XML files may change.
Q1. If I extend the MC class so I can add attributes to MC's
instance (Avoiding global variables) - will it mess with the rest
of the movie clips in my scene? I mean if all I want to do is ad a
a few dynamic string variables - it really shouldnt effect any of
the other clips would it? MC.JumpURL = "newurl.com", MC.Thumnail
="/here/image.jpg" (This would help alot)
Q2. What if I wanted to define actions of the new MC in the
class? If the MC is an extension of the MC class. Would all of my
MC's automatically take on the actions of the custom MC Class? For
instance - I want the movieclip to animate onscreen and have
rollover effects. I could do this easy if it were static - but I
need this to become dynamic. Also - there are now unknown
quantities to deal with
Q3. How exactly would I call and assign the MC its atributes
at the same time? And how do I specify this MC to use the functions
defined in the class and not the other MC's I created elsewhere in
the File.
Example. Currently I have a grid of MCs' created when the
User clicks a menu item (Another type of MC).
Each new MC animates onstage - it calls a
loadMovie(_root.thumb[0], this.Flipper) to assign and embedded MC
an image defined in the XML that was loaded and assigned because I
placed the instance on stage and wrote a MC script on each MC.
Confused - check out what I am creating at
www.vincesidwell.com/Fischer
Click Fabrication or TurboSystems menus. Both menues will
load a new set of Thumbnails at the bottom. They are loaded via an
XML loaded by the menu and a function assigns the jpgs for the main
gallery, Rollover image, and eventually a URL for a downloadable
High Res Image.
The client recently added more than 9 images per menu item. I
will need to create a scrollable thumbnail gallery with dynamic
quantities
I can manually create the MC Scroller item for static number
of buttons. But scripting an unknown for each ones links and images
is insane. So I am looking at Classes. Assign a custom class for
the flipping buttons and I should be able to assign tthem as the
XML loads, and have it automatic. (pray please please please)
Anyhelp?
Thanks

You do not have to create a new MC class to assign local
values or functions
to it. A pseudo code example:
Loop through total buttons you want to make (which can be
number of entries
in an XML file)
Create a new movieclip and load the button graphic into
this, give it a
name like
MyButtonX, where X is an increasing number based on which
button this
is. (Instead of creating
and empty movielcip, you could also attach a movie (or
button) from
library.
Assign the values and create the functions for this button
that you
would like (probably based
on information in the XML file):
MyButtonX.someVariable = node.attribues.someData;
createOnRelease(MyButtonX, someOtherParamters)
(where you have defined the function createOnRelease to do
something
like
function createOnRelease(MC, someOtherParameteres) {
MC.onRelease = function() {
do what you want to do based on someOtherParameteres
Position and resize MyButtonX
In your example you have a 3x3 grid, which might extend to
3xTOTAL,
so you'd have to use some
mathematical formula based on the value X, something like
MyButtonX._x =
(((X-1)%3)*(buttonWidths+hSpaceBetweenButtons)
MyButtonY._y = Math.floor((X-1)/3)*(buttonHeights
+vSpaceBetweenButtons
end of loop.

If you actually create a new class, than all instances of
that class will
have the methods you define for it (just like all instances
of a movieclip
has those methods. At least, have them available. That
doesn't mean they are
always in use ... like for example the onRollOver. But again,
you don't need
to create a class to give all your dynamically created
buttons a rollover
effect. (Check code above).
> Q3. How exactly would I call and assign the MC its

You use the instance name of the MC to access that MC and its
attributes/methods. For example button number 10 might look
like this:
trace(MyButton10._x);
trace(MyButton10.someVariableYouHaveDefined);
MyButton10.callSomeFunctionYouHaveDefined();
For a movieclip to access a variable that has been defined
for that instance
of the movieclip, use "this" to point to that particular
instance. So if we
defined the function "callSomeFunctionYouHaveDefined" for
button number 10
and want to access "someVariableYouHaveDefined" for this
particular
instance, then
MyButton10.callSomeFunctionYouHaveDefined = function() {
trace(this.someVariableYouHaveDefined);

Again, no need for a class for this. If you load the buttons
into seperate
MCs, and make sure to have all these MCs created inside a
common parent MC
for these buttons (which then _only_ contains these buttons).
You can move
this parent MC up and down on the stage based on the
scrollbar. And you can
read height off this MC to create your scrollbar.
You might want to check out the following tutorials at
http://www.gotoandlearn.com/:

Creating Animated Buttons
Introduction to OOP
Now, I've said many times you don't need to make your own
class to do what
you want. That does not mean you can't make your own class. I
just think
that the main problem you are facing is the dynamic part,
which you will be
facing if you make your own class or not.

Create Attachment in workflow through ABAP Class in ECC 5.0

Hi,
Wr are using SAP ECC 5.0 and i am trying to create attachment through ABAP class.
Here in ECC 5.0, macro INCLUDE cntn01_swc is not available.
I am getting an error in declaration of SOFM object, because again SWC0_OBJECT is not available.
I've tried creating the parameter as type SOFM and of type table of SOFM but it also not working.
Can anybody help me how i can create SOFM instance in ABAP class in ECC 5.0?
Regards,
Smit

Hi
I am not very much sure about ECC 5.0 environment. Firstly are you looking to create a SOFM object inside any class or program or Function module , If yes then you need to include a include INCLUDE CNTN01_SWC (No arrow brackets) if this include is not available then use INCLUDE<CNTN01> then declare a variable of type SWC0_OBJECT if you are using first include or declare of type SWC_OBJECT.
Once you include any of the includes then by making use of SWC macros you can create a object
SWC0_CREATE_OBJECT <VARAIBLE> <BOR NAME> <BORKEY> for first include.
SWC_CREATE_OBJECT <VARAIBLE> <BOR NAME> <BORKEY> for second include.

Creating a button that flips back and forth on iPad in InDesign through DPS

How do I create a button that flips back and forth on iPad in InDesign through DPS. I saw it on a food magzine on an ipad ... it's just a circle with text it in, when you click it the whole circle flips to the other side and there is a different color with different text. The circle does not change position, it just flips. Again, I want to do this so it shows up on the ipad through DPS.
Thanks,
Jay

You need to create a Web overlay. There's an HTML example you can download and repurpose in this article:

Button class not creating a button

Hi,
I have some AS3 code which I was hoping would create a
re-usable button class but it does not. I just get a blank canvas.
I am not getting any errors. Code is attached. Anyone see what is
wrong?

thanks for the response.
to instantiate this class with the var code that you posted
and I reposted. Would this code be added to the .as file or would I
put that on frame 1 of the .fla file?
Also I want to create multiple buttons and position them on a
page within a grid. With the class code I have posted, how would I
go about doing that? Lastly, I want one of two movie clips to
display once the button is clicked. Can someone explain how I would
go about that as well?
thanks

Creating a triangle using polygon class problem, URGENT??

Hi i am creating a triangle using polygon class which will eventually be used in a game where by a user clicks on the screen and triangles appear.
class MainWindow extends Frame
 private Polygon[] m_polyTriangleArr;
 MainWindow()
 m_nTrianglesToDraw = 0;
 m_nTrianglesDrawn = 0;
 m_polyTriangleArr = new Polygon[15];
 addMouseListener(new MouseCatcher() );
 setVisible(true);
 class MouseCatcher extends MouseAdapter
 public void mousePressed(MouseEvent evt)
 Point ptMouse = new Point();
 ptMouse = evt.getPoint();
 if(m_nTrianglesDrawn < m_nTrianglesToDraw)
 int npoints = 3;
 m_polyTriangleArr[m_nTrianglesDrawn]
 = new Polygon( ptMouse[].x, ptMouse[].y, npoints);
}When i compile my code i get the following error message:
Class Expected

line. Please help

Cannot find symbol constructor Polygon(int, int, int)
Can some one tell me where this needs to go and what i should generally
look like pleaseI don't think it is a good idea to try and add the constructor that the compiler
can't find. Instead you should use the constructor that already exists
in the Polygon class: ie the one that looks like Polygon(int[], int[], int).
But this requires you to pass two int arrays and not two ints as you
are doing at the moment. As you have seen, evt.getPoint() only supplies
you with a single pair of ints: the x- and y-coordinates of where the mouse
button was pressed.
And this is the root of the problem. To draw a triangle you need three
points. From these three points you can build up two arrays: one containing
the x-coordinates and one containing the y-coordinates. It is these two
arrays that will be used as the first two arguments to the Polygon constructor.
So your task is to figure out how you can respond to mouse presses
correctly, and only try and add a new triangle when you have all three of its
vertices.
[Edit] This assumes that you expect the user to specify all three vertices of the
triangle. If this isn't the case, say what you do expect.

How can i create a button with richText display instead of label

Hi All,
I'm trying to create a button that will look exactly as the regular spark button but will have more than one color in his label (Like attached 'buttonPic.jpg')
I have tried to create a new button skin and new button component that will replace the label text and will to the job, but still it looks like the button original class overides the richText definitions. (Code attached)
Maybe there is other solution?
This is my extra code in the MyButtonSkin
 
 
 <s:Label id="labelDisplay"
 visible="false">
 </s:Label>
 <s:RichText id="exLabelDisplay"
 color="0x900000"

Re: How do you create and use "common" type classes?

Hi,
You have 2 potential solutions in your case :
1- Sub-class TextNullable class of Framework and add your methods in the
sub-class.
This is the way Domain class work. Only Nullable classes are sub-classable.
This is usefull for Data Dictionary.
The code will be located in any partition that uses or references the supplier
plan.
2- Put your add on code on a specific class and instanciate it in your user
classes (client or server).
You could also use interface for a better conception if needed. The code will
also be in any partition that uses or references the supplier plan where your
add on class is located.
If you don't want that code to be on each partition, you could use libraries :
configure as library the utility plan where is your add-on class.
You can find an example of the second case (using a QuickSort class,
GenericArray add-on) with the "QuickSort & List" sample on my personal site

Robinson, Richard a écrit:
I'm relatively new to forte and I'd like to know how can you handle utility
type classes that you want to use through out your application? Ideally
what I want is a static class with static methods.
Let's say that I have a StringUtil class that has a bunch of methods for
manipulating strings.
My problem is that we have code that runs on the client and code that runs
on the server. Both areas could use the StringUtil class, but from what I
understand, I have to create StringUtil in a plan and then create a server
object of type StringUtil. The server object will eventually get assigned
to a partition. That's not good since I really want the server object to
physically reside at the server end and at the client end. (Actually, I
don't want a server object, I just want to invoke a static method of a
static class).
Any clues on how to solve this problem would be appreciated.

Your question about "utility classes" brings up a number of issues, all of
which are important to long-term success with Forte.
There is no such thing as a static method (method that is associated with a
class but without an implicit object reference - this/self/me "pointer") in
TOOL, nor is there such thing as a global method (method not associated
with a class at all). This is in contrast to C++, which has both, and
Java, which has static methods, but not global classes. Frequently, Forte
developers will write code like this:
result, num : double;
// get initial value for num....
tmpDoubleData : DoubleData = new;
tmpDoubleData.DoubleValue = num;
result = tmpDoubleData.Sqrt().DoubleValue;
tmpDoubleData = NIL; // send a hint to the garbage collector
in places where a C++ programmer would write:
double result, num;
// get initial value for num....
result = Math::Sqrt(num);
or a Java programmer would write:
double result, num;
// get initial value for num....
result = Math.sqrt(num);
The result of this is that you end up allocating an extra object now and
then. In practice, this is not a big deal memory-wise. If you have a
server that is getting a lot of hits, or if you are doing some intense
processing, then you could pre-allocate and reuse the data object. Note
that optimization has its own issues, so you should start by allocating
only when you need the object.
If you are looking for a StringUtil class, then you will want to use an
instance of TextData or TextNullable. If you are looking to add methods,
you could subclass from TextNullable, and add methods. Note that you will
still have to instantiate an object and call methods on that object.
The next issue you raise is where the object resides. As long as you do
not have an anchored object, you will always have a copy of an object on a
partition. If you do not pass the object in a call to another partition,
the object never leaves. If you pass the object to another partition, then
the other partition will have its own copy of the object. This means that
the client and the server will have their own copies, which is the effect
you are looking for.
Some developers new to Forte will try to get around the lack of global
methods in TOOL by creating a user-visible service object and then calling
methods on it. If you have a general utility, like string handling, this
is a bad idea, since a service object can reside only on a single
partition.
Summary:
* You may find everything you want in TextData.
* Unless you anchor the object, the instance will reside where you
intuitively expect it.
* To patch over the lack of static methods in TOOL, simply allocate an
instance when required.
Feel free to email me if you have more questions on this.

Subject: How do you create and use "common" type classes?
I'm relatively new to forte and I'd like to know how can you handle utility
type classes that you want to use through out your application? Ideally
what I want is a static class with static methods.
Let's say that I have a StringUtil class that has a bunch of methods for
manipulating strings.
My problem is that we have code that runs on the client and code that runs
on the server. Both areas could use the StringUtil class, but from what I
understand, I have to create StringUtil in a plan and then create a server
object of type StringUtil. The server object will eventually get assigned
to a partition. That's not good since I really want the server object to
physically reside at the server end and at the client end. (Actually, I
don't want a server object, I just want to invoke a static method of a
static class).
Any clues on how to solve this problem would be appreciated.
Also, what is the url at Sage-it that has a summary of all emails that have
been posted to [email protected]? Perhaps this question has been
answered previously.
Thanks in advance

Create an instance of my class variable

Hello all,
I'm a newbie to iPhone/iPad programming and am having some trouble, I believe the issue is that I'm not creating an instance of my class variable. I've got a class that has a setter and a getter, I know about properties but am using setters and getters for the time being. I've created this class in a View-based application, when I build the program in XCode 3.2.6 everything builds fine. When I step through the code with the debugger there are no errors but the setters are not storing any values and thus the getters are always returning 0 (it's returning an int value). I've produced some of the code involved and I was hoping someone could point out to me where my issue is, and if I'm correct about not instantiating my variable, where I should do that. Thanks so much in advance.

Selection.h
@interface Selection : NSObject {
int _choice;
//Getters
-(int) Choice;
//Setters
-(void) setChoice:(int) input;
Selection.m
#import "Selection.h"
@implementation Selection
//Getters
-(int)Choice {
return _choice;
//Setter
-(void)setChoice:(int)input{
 _choice = input;
RockPaperScissorsViewController.m
#import "RockPaperScissorsViewController.h"
@implementation RockPaperScissorsViewController
@synthesize rockButton, paperButton, scissorsButton, label;
//@synthesize humanChoice, computerChoice;
-(void)SetLabel:(NSString *)selection{
 label.text = selection;
-(IBAction)rockButtonSelected {
// [self SetLabel:@"Rock"];
 [humanChoice setChoice:1];

So in the above code it's the [humanChoice setChoice:1] that is not working. When I step through that portion with the debugger I get no errors but when I call humanChoice.Choice later on in the code I get a zero.

It worked, thank you so much. I put
humanChoice = [[Selection alloc]init];
In viewDidLoad and it worked like a charm. Thank you again.

Creating multiple instances of a class in LabVIEW object-oriented programming

How do you create multiple instances of a class in a loop? Or am I thinking about this all wrong?
For instance, I read in a file containing this information:
Person Name #1
Person Age #1
Hobby #1
Hobby #2
Hobby #3
Person Name #2
Person Age #2
Hobby #1
Hobby #2
Hobby #3
Person Name #3
Person Age #3
Hobby #1
Hobby #2
Hobby #3
If I define a Person class with name, age, and an array of strings (for the hobbies), how can I create several new Person instances in a loop while reading through the text file?
FYI, new to LabVIEW OOP but familiar with Java OOP. Thank you!

First of all, let's get your terminology correct. You are not creating multiple instances of a class. You are creating Objects of the class.
Use autoindexing to create an array of your class type.
