Handling native events

Hi,
is there any way to handle the native events on the iPaq, like the activation of the virtual keyboard. Or if this is not possible, how can you manipulate the virtual keyboard: show/hide operations.
Thx a lot,
Dragos

I used JNI to manipulate the SIP in order to turn off the word-completion feature for a password field in a Java app running on Ipaq using Jeode. I did that by starting with the code found here:
http://www.pocketpcdn.com/qa/wordcompletion.html
I made it JNI friendly, and made the call when my password field received focus. The code from the above also shows how to hide/unhide the SIP
Hope that helped,
-Brad

ABAP native Events

HI,
In any of the typical ABAP programs, we have some events that are native to ABAP runtime (e.g., initialization, start-of-selection,etc),now, i need to know that on which order these events will get executed. also below I've given the events just order them on their execution basis.
initialization
start-of-selection
top-of-page
end-of-page
at selection-screen
end-of-selection
at user-command
at selection-screen output

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The deprecated event handler "handleEvent(Event event)" has been replaced by "processEvent(AWTEvent event)" as per the docs.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.

Using native events in specific application with J2ME

I can capture native events of a cellular phone using J2ME (button of beginning and end of calls, description of effected calls) to use them in a specific application?
I can use resumeRequest() method of the MDIlet class to capture the events of the start and the end of a phone calls or services used in an J2ME application? When, as and where I can use such class?How I can pass to my application effected phone calls , sent messages SMS and the accesses the InterNet? That methods and class I must use? How I must make to develop a class that executes this type of function with JAVA? Where I can find codes of aid or sample, tutorial, tips, etc to create such functions?

Fukiku,
 Did you get this working?
 You can also try setting the environment variable java.library.path.
 Please post your stack trace to the forum as well.

I'm doing a little edge project (now in beta version) for my girlfriend (she hates the code), with examples of the animate() method and other functions like setInteval(), but when I run I get the following error in Chrome console:
Javascript error in event handler! Event Type = element [edge.2.0.0.min.js:162]
But this library is global for all projects, how is possible that trigger an error?
Example here:

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

Handling button events in large app

I'm currently examining a large swing app, and have observed the following with regard to action events.
A number of listeners (for buttons, menu items, JLists etc.) are defined at the top of the app. These variously extend MouseAdapter or implement ActionListener, depending on the type of component whose actions they listen for.
The ButtonListener definition is as follows :
private class ButtonListener implements ActionListener
public void actionPerformed(ActionEvent event)
Object object = event.getSource();
if (object == button1)
// button1 actions
else
if (object == button2)
// button2 actions
.....etc
One instance of this listener is created in the app, and is used as the actionlistener for each button. This means that the buttonlistener is quite large (as it contains the code for each button in the app).
Is this the proper way to handle button events for an app with a large number of buttons?

Thanks for the responses.
In response to theDude : I agree that defining the action listener for each button can be useful when you can see the button definition and button action in one place; one could counter that by saying that grouping all the button actions makes it easier to examine all button actions in one place.
Setting the action command isn't really an option because the application creates panels of buttons on the fly, e.g. when notification of a new customer is received, a new panel is created with a JTextPane (customer description) and a row of buttons for "Modify", "Delete" and "Print".
Several customer panels could be in existence at the same time, so setting an action command of "Modify" would not enable one to uniquely identify which "Modify" button was pressed.
This problem is currently handled by associating the panel instance with a "Customer" class instance in a hashtable. The "Customer" class consists of a JTextPane field, and a JButton for each function. When a button is pressed, the button listener traverses up the component's parents until it reaches the panel (i.e. it loops until the parent is a key on the hashtable, at which point it can retrieve the Customer instance and check which button was pressed).
In response to KPSeal : If I understand you, I would define "ApplicationAction" separately from the main app and define extensions of it in the main app for each type of action. Would this add much value over merely defining a method for each type of action in the main app and just calling this method when the relevant button/menu item was pressed/selected?
There doesn't seem to be a universal approach to event handling, but I thought there might have been one accepted strategy when an app has large numbers of buttons (some created on the fly, ruling out action commands).

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.
