Handling keypress event in ChoiceGroup

hi all,
I want to show the Cities in India in a ChoiceGroup. It is a lengthy list, so I like to make some key event in that ChoiceGroup. I am displaying the ChoiceGroup in a form. If the user pressed 'd' the ChoiceGroup must display the choices starts with 'd', and also for all the alphabetics.
please give me some idea to do this..
If any one done success with this already.... please help me..

You get the path in the event only when the document is saved under a different name/path then the original one on close.
A possible solution for your problem is to maintain the path (along with any other info) for each document you are interested in throughout the document's lifetime (i.e. open-save as-close). Unfortunately, I'm unaware about any other way to retrieve document's details for an already closed document (and may Adobe folks correct me if I'm wrong).

How to handle keypressed event for form

i have to handle keypressed event of a textfield control.
I have tried by implementing itemstatechangelistner ........
but as api specifies its behavior varies from device to device....it is guaranteed that the control is notified when losing its focus. But my requirement is to get notified for every keypressed time.....
any idea.....pls help me

Can't be done for TextField. Many devices (example:SE k700i) launch a separate editing screen to change the text in a TextField.

List that responds to keypressed events?

Hi
I am designing a midlet that needs a list which scrolls down to names based on the input from the phones letter keys (ie if the user presses the 'GHI' key then the names starting with 'G' are shown. the same as in a phones contact-list) However the problem is that there is no keypressed event for j2me Lists or Forms.
I realy don't want to have to reinvent the List from a Canvas.
Could anyone tell me the best way to handle this?
Thanks greatly
Aharon

Hmm... the small screen is a big pain, isn't it!
Suppose you dynamically filter the list of potential entries based on what has been already entered in the TextField? Something like thisString[] allNames = new String[100];
choiceGroup.deleteAll();
String filter = textField.getString().trim().toUpperCase();
for ( int i = 0; i < allNames.length; i++ )
if ( allNames.toUpperCase().startsWith(filter))
choiceGroup.append ( allNames[i], null );
}db
-- TextField, [i]not TextBox. TextBox extends Screen, TextField extends Item. ;-)

Handling keyboard events in applets?! Possible?!

Hello,
I wrote a little game that uses keyboard handling events. It is an applet that can also standalone as an application. When i run the program as a standalone application, it handles keyboard inputs fine. ie...i can press the left and right arrow keys and something happens.
But when i run my program as an applet in a web browser, the applet starts up correctly but does not handle any keyboard events. It only handles mouse events. For instance, if i press the up and down arrow keys, the browser window scrolls up and down!!! And the up and down arrow keys have a specific purpose in my applet.
QUESTION: how do i get my applet to accept keyboard inputs such as UP,DOWN, LEFT, RIGHT?

Hmm something went wrong w/ my post so i hope this doesnt show up twice.
Hey thanks a lot for helping me out. The applet/application is large so here is the main() method and the keyboard event handling class code. My question is how come the keyboard events get properly handled when i run it as a standalone application, but keyboard events go to the browser when i run it as an applet? I would post my entire code but it's over 1000 lines and spread out over 8 files. hehehe.
Here is main():
public static void main(String[] args)
      MyProgram applet = new MyProgram();
      applet.isStandalone = true;
      JFrame frame = new JFrame();
      frame.setTitle("Physics: Kinematics");
      frame.getContentPane().add(applet, BorderLayout.CENTER);
      applet.init();                        // initialize the applet inside frame
      applet.addKeyListener(kbHandler);     // kbHandler is a keyboard handling object
      applet.start();
      frame.setSize(APPLETWIDTH,APPLETHEIGHT);
      Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
      frame.setLocation((d.width - frame.getSize().width) / 2, (d.height - frame.getSize().height) / 2);
      frame.setVisible(true);
      // private inner class to terminate the Application when frame closes
      frame.addWindowListener(
        new WindowAdapter()
            public void windowClosing(WindowEvent e)
                System.exit(0);
      frame.show();
   }"kbHandler" is the keyboard event handling object. It gets initialized in the applet.init() method.
kbHandler = new BMkeyboardHandler();And here is the keyboard event handling code:
// ===== keyboard event handler ===========
   private class BMkeyboardHandler implements KeyListener
        public void keyPressed(KeyEvent e)
            pushedKey = e.getKeyCode();
            // General administrative key actions
            if(pushedKey == KE.VK_H)
                actionArea.toggleHelpMenu();
                actionArea.repaint();
            else if(pushedKey == KE.VK_C)
                actionArea.toggleCtrlMenu();
                actionArea.repaint();
     }So there it is. Again, the program handles events fine as a standalone application. But running it as an applet in a browser (and even the appletviewer) doesnt let me handle keystrokes.

Help -- keypressed events

Hi, I have a texfield in which I want the users to enter time in the following format: hh:mm:ss
My problem is, I want the colons to appear automatically when the user is entering hh and mm fields. I tried using the keypressed event but I am not able to make it work very neatly, i mean there is some problem or the other when I try various inputs, try backspace, delete etc.
Anybody got any inputs?

Actually I am using jdk1.3 -- therefore I can't use JFormatted TExtfield.
I went thru the Doc listener api -- u r right, i don't need that.
All i need is a simple code check in my keypressed event handler -- but I am unable to write that.

Event handler : handleEvent(Event event)

Good day,
The deprecated event handler "handleEvent(Event event)" has been replaced by "processEvent(AWTEvent event)" as per the docs.
With some research, I came up with this little conversion chart :
item handleEvent processEvent
====== ============ ============
x event.x event.getX()
y event.y event.getY()
id event.id event.getID()
target event.target ???
====== ============ =============
I'm just trying to compile a list of conversion for deprecated APIs with some extra information to "ease" the transition process.
Is the above information right or am I still missing the boat ?
Please apply necessary corrections wherever applicable.
Best regards.

Is it possible to handle multiple events using Jscript for a button in Apex

Hi,
I've application wherein in one of the pages for a button, I need to trigger 2 events as: 1. redirect to a new page upon 'click' of the button
2. display a set of values on 'mouse over' that button.
I'm able to handle both separately, but not in one button. I would like to know if there is any limitation in Apex that we cant handle multiple events? Currently I've put a text item near the button, and called the Jscript for mouse over event in that as a temporary workaround. Can someone let me know if this is feasible? If not any other alternative to handle this?
Thanks in advance,
gsachidh

Hi Gsachidh,
well interesting problem you're facinng. Indeed, it can't be specified using the 'Button Attributes' So we have to come up with an workaround.
A quick en dirty solution would be to specify it with the 'Optional URL Redirect options'. In a normal button, with processing on same page, this would be 'no target'. but in case of additional things to be done this can be used, using an target URL. I used this many times, in example with popUp windows for refreshing the caller object when changes are made. In your case we have to add next to the href an onmouseover event. this can be done with;
Target set to => URL
URL - target => javascript:doSubmit('<button_name>');" onMouseOver="javascript:showTooltip('tooltip');"
Here the " is the key, letting ApEx know the target (href) is doSubmit('<button_name>'), just like when no target would be specified and adding a new javascript event; onMouseOver.
Although this is a dirty solution in my opinion, it is the best i could come up with. I have another idea in how to do this, that is by adding this event dynamically with javascript with an addEvent. But i don't have an example at the moment for this scenario.

Reg : Cross browser issue while handling LOV event on KeyFlexFeild

Hi OA Gurus,
We are encountering issues on R12.0.6, JDev 120Rup6.
We have the following test case and code changes.
Requirement:
We have OA page where we have one KeyFlexFeild item and a normal LOV. Page items are part of one AM and LOV is in another AM.
The requirement was to make LOV dependent on keyFlexfeild. Test case is mentioned as per following flow.
1.     User changes cost center segment of Accounting Flex(Key flex) using Cost center LOV.
2.     Another LOV in the same page should be dependent on new value of cost center as modified in step 1.
Solution Implemented:
Describing in the 3 steps
1) Here the KeyFlexFeild is expense account. Whenever User changes any segment, we handle
‘lovValidate’ and ‘lovUpdate’ events on KeyFlexFeild in processFormRequest of controller.
2) Retrieve the value of cost center segment using getSegmentsQualifiedBy(), Update corresponding VO attribute of the LOV query parameter.
3) Forward the request to current page so that LOV will have modified value with updated query.
4) Forwarding to current page is must because LOV is built with another AM and will loaded only when page is built.
Issue:
This works fine on internet explorer. When trying to run the same in Mozilla we have following issue
1) User modifies one of the segments of expense account and make a tab – out
2) Now the page refresh happens
3) Now in the same page no other LOV or no other button works. He can’t click on any button for submit or cancel.
LOVs will not open even after clicking on it.
Code changes:
//Step1 – Handle LOV events
String source = pageContext.getParameter(SOURCE_PARAM);
String eventType = pageContext.getParameter(EVENT_PARAM);
if(source !=null && eventType != null) {
if(source.startsWith("Acct") && eventType.equals("lovUpdate") || eventType.equals("lovValidate") ) {
KeyFlexfield flex = (KeyFlexfield)lkff.getAttributeValue(OAWebBeanConstants.FLEXFIELD_REFERENCE);
// Step -2 Updating the corresponding VO attribute for LOV to get the modified the value
Segment[ ] segmentL = flex.getSegmentsQualifiedBy(FA_COST_CTR");
CostCenterValue = segmentL[0].getValue().getValue();
if(CostCenterValue != null ){
sampleViewObject.getCurrentRow().setAttribute("ToCostCenter",CostCenterValue);
OAFormValueBean formValueBean = (OAFormValueBean)webBean.findIndexedChildRecursive("ToCostCenter");
if(formValueBean != null)
formValueBean.setValue(pageContext, CostCenterValue);
OAMessageLovInputBean formValueBean1 = (OAMessageLovInputBean)webBean.findIndexedChildRecursive("ReceivingApprover");
if(formValueBean1 != null)
formValueBean1.setValue(pageContext, null);
else
sampleViewObject.getCurrentRow().setAttribute("ToCostCenter",null);
//Step 3 – Forward the request Current Page again
pageContext.setForwardURLToCurrentPage(null, true, ADD_BREAD_CRUMB_YES, (byte)0);
We have following questions.
a)     Solution implemented by us is correct ? or we have to implement it in another way ?
b)     Is OA version mentioned above supported on Mozilla browser version 3.x ? This issue is not occurring on Mozilla 1.x while running from JDev.
Please let us know if any additional details required.
Thanks for help in advance.

Keypress Events

Hi, everybody, it is my first question to you all.
Does anybody have any function that would capture keypress events, or
any information that would be helpful in capturing them? For example,
when a user presses the <down arrow> or F1 key. I am currently using
the AfterValueChange event to capture keys that display.
Thanks,

Hi all,
Actually, I don't think you can trap keystrokes on a UserWindow but on =
some WidGets (like DataFields), you can set to TRUE the 'Validate on =
KeyStroke' option in the properties dialog .
Thus, when the WidGet has the focus and the user send a keystroke, you =
can trap this event with the 'AfterValueChange' event. If someone knows

how to trap keystrokes on a UserWindow, I am also interested !

Hi Manuel and Martin,
Unfortunately, for Forte V2.0, Manuel is correct. But Forte has added a

feature that allows you to trap any keystroke in Forte R3, which is =
currently in beta.
If you are a beta site, look in the Forte Release 3 Beta Features manual

page 169, the window class SetAsFunctionKey method.
If you are not a beta site and want this functionality in R2,=20
you would need to do some tricks with menus or data fields, as Manuel =
indicated.

I think all of us want to know if we can indeed trap ANY keys.
The answer is ALMOST, including escape, spacebar, enter, backspace, tab,
=
navigational (up,down,left,right,end,home), digits, alpha, numeric =
keypads, insert, delete.
But not keys such as left shift, right shift, left Alt, right Alt, left =
Ctrl, and right Ctrl (Helpful for games...).
Don't forget that we are talking about release 3.

Handling Button Event

Hi all,
i am using a 'When-Validate-item' trigger in this i am doing a validation,
when user try to enter amount greater than the given amount(This is needed validation)
and also i am regenerating new lines(Creating new records when button pressed)
when i am regenerating i should not validate.
How to handle button event
Thnx
Raj

Hi...
The WHEN-VALIDATE-ITEM Trigger fires once you updated a field. Be sure you raise
form_trigger_failure when amount is invalid. So, the cursor stays in field amount. You cant
leave this field until the amount is not valid.

How to handle Valuechange events, when page bean is in request scope

Hello balusc and forum mates,
I want to know is there any good way to handle ValueChangeEvents events, when the page's bean in request scope.
My problem is, I have a page having more than 1 value change event so How can I maintain page values at backing bean. My bean is request scope, I can't change to session scope.
Please I really need it.

Hi Frank...
In my code i used almost same logic as Andrejus Baranovskis has explained in his Editable Table example...
You can refer that example to see what problem I'm facing...
http://andrejusb.blogspot.com/2007/04/create-edit-and-delete-operations-in.html
The Bean Scope in this Example is Session scope...Save button is working fine...
But as i Change the bean scope to Request scope then Save button is not working for Edit but it is working for Delete Action very well..
I want that save button should work also for Edit action in Request Scope..
Please Make me understand that why it is happened like that..
and help me to find the solution..
and Also if you have a better document to Explain the life cycle of Application in Different Bean Scope...So please provide me that Doc to me...
It would be a great help for me to understand the concept of session...
Thanks Frank
