How to fire mouse wheel events to parent container?

Hi,
When I create a JPanel (let's say jParent) inside a JScrollPane and this JPanel is larger than the current viewport I can use my mouse wheel to scroll the JPanel's containt without coding anything about that.
But if I add another JPanel-derived component (let's say jChild) to the first JPanel, mouse wheel events are not received by the first JPanel when the mouse is over the new added child JPanel.
How can I forward child's mouse wheel events to the first JPanel?
If I use:
jChild.addMouseWheelListener(jParent)I must implement a mouseWheelMoved() method in jParent that requires some code to work while it was doing it byitself before...
Thanks in advance for any help :-)
Regards,
Lara.

you have a mouseWheelListener added to jChild?
if so, in the mouseWheelMoved code include this line
jParent.dispatchEvent(mouseWheelEvent);//or to the scrollpane

OT: Remind me, please, how to fire an onload event with javascript!

How do I do this without screwing with the body tag?

==================

I just want to add a post in clarification -
1. I was using EasyFaq (a very nice extension from
ValleyWebDesigns) in a
non-standard way. Had I used it out of the box, so to speak,
I would not
have had these problems.
2. To reiterate, the problems I were trying to solve were, in
no way,
related to standard use of EasyFAQ.
3. My problems were solved both by following the suggestions
of Al Sparber,
and with help from E. Michael Brandt.
4. Indeed, I had some invalid code on the page, and it was
the presence of
that code that made things get a little cockeyed.

How to fire an onblur event for htmlb:inputfield ?

Hi All,
I have a problem in creating in ONBLUR..for input field.
What i want is when i give input to the input it goes to DB and retriving some data and visible to next Dropdown.
For this if i give input to input field and press any key then it will goes to db and getting data.
I am stricking over here .
Please guide me for this.
Thanks
Nageswara.

so what you need is a javscript function to get triggered onblur event and it should generate server event.
check out the following code sample.
<htmlb:inputField id         = "test"
                        alignment = "LEFT"
                        size       = "10"
                        type       = "STRING" />
      <bsp:htmlbEvent id      = "myid"
                      onClick = "myonclick"
                      name    = "ValueChanged" />
        <script for="test" event=onblur type="text/javascript">
      ValueChanged();
      </SCRIPT>

JTree - How do I fire a valueChange Event from a keyPressed Event?

Hi,
I have been stumped trying to figure out how to fire a valueChange event in my JTree from a keyPressed event.
When a user changes tree node using the mouse a valueChange event fires. In my program the valueChange executes some code that must be done. I want to get my JTree to work, so that if a user is nagivating the tree using the keyboard, the code is only executed if they press the enter key.
Below is a little demo program of what I am attempting to accomplish. Any suggestions would be greating appriciated.
Thanks,
Corey

How to make jcombobox display all by itlself?

Hello all -
Is there a way to make a jcombobox object display its column of items implicitly?
For example, suppose a program has a combobox filled up with names. And, suppose the first item says "toggle sort", which affects how the items are sorted in the combobox (eg, pressing it should cause the list to sort the displayed names based on first name, another press bases the sort on the last name...). The behavior I am aiming for is that when the user presses the "toggle sort" item, the combobox displays its items again awaiting further selection from the user (but not the first item). Know how to fire such an event?
private void namesComboBoxActionPerformed(ActionEvent evt) {
   int selected = namesComboBox.getSelectedIndex();
   if (selected == 0) {
      // some code should result in the namesComboBox displaying its items again. What is it please?
}

Here is a simple code, I don't know if its the correct way to do this sort of thing but it works:
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.ArrayList;
import java.util.Collections;

How to fire event to generate insert message for the child objects?

We are in process to integrate CRM On Demand and existing Microsoft SQL DB.
We have the following problem:
For ex., we have CRM Object_1 that already synchronized with the SQL DB. CRM also has independent Object_2 and its child Object_2.1
We dicided that we want to connect the Object_2 as child to the Object_1.
The question is how to fire event to generate insert message for the Object_2 and Object_2.1?
What is the best technique? Is it possible to do it by workflow configuration or it needs to be done programmatically?
Thanks,
Dmitry
Edited by: 955827 on Aug 29, 2012 11:57 AM

Hi,
integration events can be generated only via worklow. You will need to create separate workflows for each record type (regardless if it is child or parent) because a workflow for the parent record type will not trigger when a child record is created/ associated. Also, the association workflows will trigger only when the specific event occurs.
There is not way to generate the integrtaion events programatically. They are generated by workflows and are read/ interpreted by a code extension.

How to fire an event dynamically in JSF Page

Hi All
How to fire an event dynamically in JSF Page?
Thanks
Sudhakar

Hi,
Thanks for the response. I mean to say, if I create the components dynamically then how can I fire events for those components.
In otherwords,
If I create the Button dynamically with particular ID being set to that component, then how can I call button action event when the button is clicked??
Hope you understand
What is the role of MethodBinding mechanism here??
Thanks

How to fire table column model event?

I found that the method to fire column changed event are:
protected void      fireColumnAdded(TableColumnModelEvent e)
          Notifies all listeners that have registered interest for notification on this event type.
protected void      fireColumnMarginChanged()
          Notifies all listeners that have registered interest for notification on this event type.
protected void      fireColumnMoved(TableColumnModelEvent e)
          Notifies all listeners that have registered interest for notification on this event type.
protected void      fireColumnRemoved(TableColumnModelEvent e)
          Notifies all listeners that have registered interest for notification on this event type.
protected void      fireColumnSelectionChanged(ListSelectionEvent e) They are declared as protected. How can I use them? I added a column to JTable and want to fire this event. I know I can use AbstractTableModel.fireTableStructureChanged() method, but it cost more time.
Does anyone of you use these methods? How do you use it?
thanks

It's a limitation of the TableModelEvent design: you can only signal the entire structure changed (with fireTableStructureChanged), but not individual columns added or removed.
A proper solution would extend TabelModelEvent with column added/removed events and extend JTable to handle those.
Another solution is to let the TableModel define all possible columns in advance and hide the ones not wanted in the JTable until they are needed.
A dirty solutions breaks the model/view separation where the model can access the TableColumnModel to add/remove columns when needed.

How to fire another event handler for postprocess stage

Hi All,
I have 3 custom event handlers for postprocess stage, for modify action on user object. The problem is tah only one event handler is executed - I use EntityManager API to modify user object. How to fire another event handlers? Do I have use UserManager API?
best
mp

As Bikash stated, used a single event handler. You can put if statements in there to identity the operation, as well as if statements if the parameter is found i the list of attributes being modified. This way you will only perform the action when necessary.

JDev 10.1.3 ADF: How to fire an event when clicking a Radio Button

I have a <af:table> component with the following code for my radio button
<af:tableSelectOne text="Select and"
binding="#{backing_viewFees.tableSelectOne1}"
id="tableSelectOne1"
attributeChangeListener="#{backing_viewFees.tableSelectOne1_attributeChangeListener}"
autoSubmit="false">
When I click the radio button it does not fire up my event in my backing bean?

Thank you for the suggestion...it does work and fires the event, but it is still not selecting the current record when I try to perform an Update or Delete.
I had to modify your code a bit in order for it work in JDev 10...used the JUCtrlValueBindingRef instead of the FacesCtrlHierNodeBinding.
Here is what my af:table tag looks like:
<af:table value="#{bindings.FeesView1.collectionModel}"
var="row" rows="#{bindings.Fees001View1.rangeSize}"
first="#{bindings.FeesView1.rangeStart}"
emptyText="#{bindings.FeesView1.viewable ? \'No rows yet.\' : \'Access Denied.\'}"
selectionListener="#{backing_viewFees.tableSelectOne1_attributeChangeListener}"
binding="#{backing_viewFees.table1}" id="table1">
If I put back my 2 original attributes, then my Delete and Updates work.
selectionState="#{bindings.FeesView1.collectionModel.selectedRow}"
selectionListener="#{bindings.FeesView1.collectionModel.makeCurrent}"
Here is my code in the backing bean:
public void tableSelectOne1_attributeChangeListener(SelectionEvent selectionEvent) {
JUCtrlValueBindingRef binding = (JUCtrlValueBindingRef)this.getTable1().getSelectedRowData();
if (binding != null) {
Row currentRow = binding.getRow();
if (currentRow != null) {
System.out.println(currentRow.getAttribute("CurrentRecordInd")); // this does print my selected value!!!!
}

How to fire a window closing event, not clicking the X button of the UI

I�ve an application that uses a WindowListener for the WindowClosing event of a JFrame. When the user presses CTRL-Q I needed to fire a windowClosing for that frame, in order to detect it and take some actions in the class referencig the JFrame (this class has the windowListener).
setDefaultCloseOperation was not good for me, so i fire the windowClosing event with the following code:
private void exitMenuItemActionPerformed(java.awt.event.ActionEvent evt) {
    WindowEvent we = new WindowEvent(this,WindowEvent.WINDOW_CLOSING, null, 0, 0);
    this.getWindowListeners()[0].windowClosing(we);
}Hope this is the right way to fire the event and this helps someone. If not please code a better way,
Alonso

Yes, that works and looks better:
private void exitMenuItemActionPerformed(java.awt.event.ActionEvent evt) {
   this.dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING));
} "this" refers to the JFrame.

JComboBox Action Event problems

I have a complex UI with which I am having action event issues. Basically, the panel displays info about an object, which can be selected from within the panel through a button/popup window mechanism. A JComboBox (#1) selection determines the contents of another JComboBox (#2) on the same panel. Currently an ActionEvent fires when the user makes a selection using #1 that updates #2. This fuctions correctly with repeated testing so long as a new object is not selected.
When a new object is selected from within this panel this ActionEvent no longer fires. JComboBox #1 will be updated correctly and #2 will reflect the initial selection in #1, but user selections in #1 will not fire the ActionEvent and thus #2 is never updated.
Any help is appreciated. I feel like I'm missing something basic here, but I've stared at it for long enough...

By the way, the workaround is to use the ItemListener as the ItemStateChanged Event is fired reliably.

How to perform an autocheck event when the field changes in ALV

Hi everybody,
how can I build an event or something which would make my 'wa_fieldcat-checkbox' set to 'X' (auto checked) everytime an editable field in the ALV is changed manually by the user?
I want to perform this task in order to avoid asking the user to manually check the "check box" field everytime wants to make a change, since after the user's changes in the ALV I want to sort the itab with the check box column of the edited items.
Thanks,
Denis M

Hi Denis,
For ALV a FM REUSE_ALV_GRID_DISPLAY is available.
The FM, has events as importing option.
SLIS_T_EVENT
EVENT - Basically this is the FM to handle Event's. When the user needs to do
some event operation like when double clicking the a particular field we need to
perform some operation. These events are captured by this FM.
slis_ev_data_changed -- To capture user command
slis_ev_user_command -- To capture data changed.
Also please refer the below link in scn. This shows sample code to capture ALV grid data changed.
http://scn.sap.com/thread/261210
Hope this will solve the problem.
Thanks,
Soundarya.
