Is there any event in checkBox?
Can you help me on how will I put an event in a checkBox without using JBUtton.
once I put a check in checkBox, it will automatically make an event. For instance changing the label text.
Can you give me a sample, what will I use. Thank you very much in advance.
Here's my code. What I want here is that, when i selected the checkbox, borderLayout.NORTH will be view the JTextField, when I deselected it borderLayout.NORTH will be view JCOmboBox...
There is an error occur, it doesn't change the boderLayout.North
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import javax.swing.event.*;
public class combo extends JFrame {
JCheckBox check;
JTextField buton;
JComboBox cmb;
public combo() {
getContentPane().setLayout(new BorderLayout());
buton = new JTextField();
buton.setBackground(Color.red);
cmb = new JComboBox();
cmb.addItem("dfds");
check = new JCheckBox();
check.addItemListener(new CheckboxColorChanger(check, buton, cmb));
getContentPane().add(cmb,BorderLayout.NORTH);
getContentPane().add(buton,BorderLayout.NORTH);
getContentPane().add(check,BorderLayout.CENTER);
setSize(300,200);
setVisible(true);
class CheckboxColorChanger implements ItemListener {
JCheckBox check;
JTextField buton;
JComboBox cmb;
public CheckboxColorChanger(JCheckBox check,JTextField buton,JComboBox cmb) {
this.check = check;
public void itemStateChanged(ItemEvent e) {
if (e.getStateChange() == ItemEvent.SELECTED) {
// To change the color of the checkbox . . .
buton.setVisible(true);
cmb.setVisible(false);
check.setBackground(Color.yellow);
check.setForeground(Color.black);
else if(e.getStateChange() == ItemEvent.DESELECTED) {
// To change the color of the checkbox . . .
buton.setVisible(false);
cmb.setVisible(true);
check.setBackground(null);
check.setForeground(Color.black);
public static void main(String args[]) {
new combo();
}

Is there any event that triggers when you switch between components?
is there any event that triggers when you switch between components?
like for example... when i switch between components, i need a function to fire everytime i switch...
ive tried show, hide, and initialize... and none of them work...
any ideas or help is greately appretiated!!Depends on what you are trying to do,
you have mouseover and mouseout and mouseclick events which you can use on the component and write code to deal with what you want to happen when you change focus. You have keypress event which would allow you to monitor tabbing between components, remember that in most events the currentTarget and target values will give you the information you need to handle component interaction.
so
[Bindable] private var CurrentObject: Object; <------- use this as a pointer to what ever object you are currently focused on or just to indicate things have changed
addeventListener(MouseEvent.CLICK,myCompponentSwap);
protected function myComponentSwap(e:event): void
if (CurrentObject !=e.currentTarget && CurrentObject != null)
do what you want becuase a component switch just happened
CurrentObject = e.currentTarget;
Hope this gets you started.

Is there any event in windows universal app (wp8.1&win8.1) that fires when screen locked and unlocked with in the app
Right now, I am using this below mentioned event

CurrentWindow_VisibilityChanged;, but it fires even when app relaunches.
Please anybody help me to solve this issue.Thanks for your early reply. but, those are system triggers used in background task. I want an event that fires when screen gets locked. like this...(a networkstatuschangedevent)
NetworkStatusChangedEventHandler
networkStatusCallback =
newNetworkStatusChangedEventHandler(OnNetworkStatusChange); -
Are there any events associated with a Blocks Scrollbar?
I'm using a multirecord block and its associated scrollbar. When the records are scrolled using the scrollbar, record focus doesn't necessarily change but the position of the record within the block does.
Are there any events available to monitor the activity of the blocks own scrollbar?
regards
MalcolmHello
Sorry , there are no events associated with the ScrollBar. -

are there any events to script a component when dragged and dropped into the parsys area?
The cq:listeners node of a component's cq:EditConfig has a number of events that fire with relation to the edit mode drag'n'drop stuff. You would probably want to hook one or more of the insert ones (beforeinsert, beforechildinsert, afterinsert, afterchildinsert).

Is there any event listener for changing the selection of layer?
Hi all,
I am looking into an event listener which fires on changing the selection of layer. I found 'Select' event listener which fires on selecting the different object.
Actually the problem with Select event listener is that when we select an object and move it and deselect it by clicking on the document, event fires on the selection of that object. But if we again select the same object and move it, no event is fired at that time.
Is there any workaround of this? So that the event is fired every time when we select the same object.
Please help me on this..
Regards,
VG.Thanks for the reply..
Actually I want the same behaviour as in illustrator i.e
- Select a layer. (Notifier calls the listener)
- Move it.
- Click on the document.
- Again select the same layer. (Notifier calls the listener again)
- Move it.
But in photoshop,
- Select a layer. (Notifier calls the listener)
- Move it.
- Click on the document.
- Again select the same layer. (Notifier doesnot calls the listener again as the layer is already selected in panel as you explained.)
- Move it.
Is there any way to get the same behaviour of illustrator in photoshop? -

Is there any event will fire on tabkey.
I wanto set focus when user navigates from one ui element to another ui element using 'tabkey' from the keyboard.
i get to know we can use
view->request_focus_on_view_elem( lv_v_elem ).
this can be code in modifyview.
but when i use 'tabkey' modifyview doesn't get trigger then how shall i handle.
one more thing is i am also using interactive forms, after user fills the last field in the interactive form(can be 2,3 pages) then he press tab the control should go to wd ui element( eg: save or some other ui element on the screen).
please let me know.
Thanks,
Mahesh.GattuYes,Thomas you are right i can understand this.
But my requirement is like i am having an interactive form element on my view with other UI elements of webdynpro like input fields and buttons.
i need to set focus of the cursor to one of the ui elements on view (Button etc ) when user enter the last field of the interactive pdf form.

Is there any event callback for "pre/post-register/unregister" object?
Dear all,
We noticed that there are rich set of event callback provided by TopLink, including "pre/post-Refresh/Build/Clone/Merge". However, we cannot found any callback method for "pre/post-register/unregister" events. They will be very useful, if we to manage the internal status of register/unregister to indicate whether it is still under the control of TopLink.
Thanks and regards,
WilliamWilliam,
Those specific events do not exist. The postClone event is called after an object is registered. This is frequently used to copy non-persistent values from the cached original into the working copy.
There is also the ability to customize the clone/copy policy used by TopLink in creating the working copies in the UnitOfWork.

Is there any Event Listener to identify change in a local File
Hi All,
I 'm fetching data from a local XML file and showing it in flex. But the xml file will be modified randomly by another java program. The change in local xml file has to be reflected in swf(already loaded) , with out reloading the page.
Please let me know, if there is any way in which I can dynamically show the change in a source file on to the screen with out reloading the page.
Thanks in advance ...
Regards,
Sandeep.I don't think there is an event in Flex as you generally do not have access to the local file system.

Is there any event of swip left and swipe right in ListView control ?
HI
As in Android phone in call list we can call to some one on right swipe and can message to same person on left swipe. Is it exactly possible in ListView Control for Windows Phone or not?
Actually I need to get the Swipe left and right Event on these bases I have to download and delete the selected listView item.
sandeep chauhanHi Sandeep,
That probably require you to do some extra coding on ManipulationDelta event.
We can get the initial touch point at from ManipulationStarted while we can get current point from ManipulationDelta, do some calculation we can know whether user swipe left or swipe right.
