Custom Button Event Handler

I'm working on a form that inserts data into my database. The normal Insert PL/SQL just does "doInsert". I want to add in the PL/SQL Button Event Handler a condition statement as follows:
IF :new.name_id != null THEN
doInsert;
ELSE
"do something else"
END IF;
"name_id" is one of the form items. I want to check the value in name_id before I insert it into the database. What is the correct verbage in order for this condition to work -- :new.name_id does not work.
Thanks
Susan

Htp.p doesn't work from the custom button event handler ...

Hi,
I am trying to pop up an alert from the custom button event handler. I created a button and put the following code.
htp.p('<script language='JavaScript1.3">
alert ("Test Message");
</script>;
But alter doesn't show up after clicking the button.
Thanks

OK i've attached them and copy/pasted the relevent parts. The parent window is the SFLB file.

Is there a C# example of using the ExpressionEdit Control Custom Button Event Handler

TestStand 4.1
C# 2008
I have added the event handler to the ExpressionEdit events as I would any event handler:
exprEdit.ButtonClick += new NationalInstruments.TestStand.Interop.UI.Ax._ExpressionEditEvents_ButtonClickEventHandler(_ExpressionEditEvents_ButtonClickEvent);
Next, I create the Event Handler using the syntax
public void _ExpressionEditEvents_ButtonClickEvent(NationalInstruments.TestStand.Interop.UI.ExpressionEditButton btn)
I get the following error when I try to build:
Error 1 No overload for '_ExpressionEditEvents_ButtonClickEvent' matches delegate 'NationalInstruments.TestStand.Interop.UI.Ax._ExpressionEditEvents_ButtonClickEventHandler'
I assume this means that I don't have the correct parameters or types in my Event Handler declaration but it matches the Object Browser. Any ideas on what I am missing?
Solved!
Go to Solution.

Try removing the "Ax." from your namespace qualifier as I marked below. I think you want the one in just the UI namespace.
Edit: well not necessarily. Is your exprEdit variable declared as "NationalInstruments.TestStand.Interop.UI.Ax.AxExpressionEdit" or as "NationalInstruments.TestStand.Interop.UI.ExpressionEdit"?
If it is an AxExpressionEdit then I think you will want your event handler to look like this:
void exprEdit_ButtonClick(object sender, NationalInstruments.TestStand.Interop.UI.Ax._ExpressionEditEvents_ButtonClickEvent e)

How to add a custom PL/SQL code for a button event handler

Hi All,
I am a toddler in using Oracle Portal. So please forgive me for my ignorance.
Q : How do I add a custom PL/SQL code for a button event handler?
Basically, I would like to write MY PL/SQL function and call it. I could see that we can write "CUSTOM" code as "PL/SQL button event handler" in the form design window. But the question is that it expects only a "call" to procedure. But where do I define the procedure then? If I insert the procedure from the backend, it gets flushed the next time I compile my form.
Hope I am able to explain my point.
Thanks in advance,
Abbas.

'Call' in PL/SQL button event handler

I have created a form with only one 'Custom' button on it.
In the PL/SQL button event handler, in 'Custom' event item, I
inserted some PL/SQL code and, at the end, a call like the
following:
my_url:= 'PORTAL30.wwv_component_control.run_as_portlet?'
|| 'p_module_id=' || '2836550185';
call(my_url,return_url);
I have a compilation error:
"PLS-00201: identifier 'CALL' must be declared"
I also tried to put this code in 'On successful submission of a
form'. I have no compilation error but it doesn't work.
Anybody knows hw to solve this problem?
Thanks.

Hello Antonnella,
I have a good tip for you:
write the next scirp in the 'On successful submission of a
form'field in the form where you want to call the component:
declare
l_url varchar2(2000);
begin
l_url := 'the url of the component you want to call' ;
PORTAL30.wwa_app_module.set_target(l_url,'CALL');
end;
you can get the url from:
develop -> call interface:show -> Example of Call from URL .
Success,
Haseeb

We need validate the sal of an employee, and if it is bigger the value musts
not be inserted.
We trying a code like the one shown in the note 134312.1 'HOW TO PASS A
PARAMETER FROM A PORTAL FORM TO A STORED PROCEDURE' and it works in the insert event of the insert button (using 'PL/SQL Button Event Handler') and it works, but we need to show a message that says the data wasn't inserted. How can we do this?
The code we used is:
declare
v_deptno scott.emp.deptno%type;
v_empno scott.emp.empno%type;
v_sal scott.emp.sal%type;
mySal scott.emp.sal%type;
v_string varchar2(256);

if mySal < v_sal then
doInsert;
else
-- We want to display a message here, when mySal > v_sal
end if;
end;

I did something similar but wasn't using a stored procedure. Couldn't you set a flag variable once you know you're not doing the insert and in the "before displaying the form" section put an IF to check if your flag was set, and if so do an HTP.Print('You are overpaid buddy!');
Then just reset your flag.

my proc is working fine in sql*plus but its showing errors in pl/sql button event handler.

DBMS_OUTPUT.PUT_LINE (LOC1);
Exception When No_Data_Found then
dbms_output.put_line('Entred name is not found');
When Others then
Null;
End;

Hi,
you have to use
htp.p('<SCRIPT LANGUAGE="Javascript1.1">
document.all("FORMNAME.DEFAULT.ATTRIBUTENAME.01").value="'||DNAME1||'";
document.all("FORMNAME.DEFAULT.ATTRIBUTENAME.01").value="'||LOC1||'";
</SCRIPT>
instead of
DBMS_OUTPUT.PUT_LINE (DNAME1);
DBMS_OUTPUT.PUT_LINE (LOC1);
where formname is your form name and attribute name is the field name on the page.

Button Event Handler in a JList, Please help.

Hi everyone,
I have created a small Java application which has a JList. The JList uses a custom cell renderer I named SmartCellRenderer. The SmartCellRenderer extends JPanel and implements the ListCellRenderer. I have added two buttons on the right side inside the JPanel of the SmartCellRenderer, since I want to buttons for each list item, and I have added mouse/action listeners for both buttons. However, they don't respond. It seems that the JList property overcomes the buttons underneath it. So the buttons never really get clicked because before that happens the JList item is being selected beforehand. I've tried everything. I've put listeners in the Main class, called Editor, which has the JList and also have listeners in the SmartCellRenderer itself and none of them get invoked.
I also tried a manual solution. Every time the event handler for the JList was invoked (this is the handler for the JList itself and not the buttons), I sent the mouse event object to the SmartCellRenderer to manually check if the point the click happened was on one of the buttons in order to handle it.
I used:
// Inside SmartCellRenderer.java
// e is the mouse event object being passed from the Editor whenever
// a JList item is selected or clicked on
Component comp = this.getComponent (e.getX(), e.getY())
if(!(comp instanceof JButton)) {
          System.out.println("Recoqnized Event, but not a button click...");
          //return;
} else {
          System.out.println("Recognized Event, IT IS A MOUSE CLICK, PROCESSING...");
          System.out.println("VALUE: "+comp.toString());
What I realized is that not only this still doesn't work (it never realizes the component as a JButton) it also throws an exception for the last line saying comp is null. Meaning with the passed x,y position the getComponent() returns a null which happens when the coordinates passed to it are outside the range of the Panel. Which is a whole other problem?
I have yet to find an example on the web, using Google, that demonstrated using buttons inside a JList.
Can anyone help me with this. Thanks.

A renderer is not a component, so you can't click on it. A renderer is just used to paint a representation of a component at a certain position in your JList.
I have yet to find an example on the web, using Google, that demonstrated using buttons inside a JList.Thats probably because this is not a common design. The following two designs are more common:
a) Create a separate panel for your JButtons. Then when you click on the button it would act on each selected row in the JList
b) Or maybe like windows explorer. Select the items in the list and then use a JPopupMenu to perform the desired functionality.
I've never tried to add a clickable button to a panel, but this [url http://forum.java.sun.com/thread.jspa?threadID=573721]posting shows one way to add a clickable JButton as a column in a JTable. You might be able to use some of the concepts to add 2 button to the JPanel or maybe you could use a JTable with 3 columns, one for your data and the last two for your buttons.

Button event handler problem

Hello,
I need to add an Event handler to a button on my JSP page. The page refreshes very three seconds for other use.
First, I added the following segment to the page.
<head>
<title>Event handler test</title>
<script type="text/javascript">

</script>
<meta http-equiv="refresh" content="3">
</head>
<input type = "button" name = "add" value = "Add" onclick="funAdd()" />
Every time I clicked the Add button, the alert message appeared. It showed the expected result.
Then, I replaced alert("Your name is already in the list."); with
<%
JOptionPane.showMessageDialog(null, "Your name is already in the list.", "Error message", JOptionPane.ERROR_MESSAGE);
%>
in funAdd().
But, the error message showed automatically every three seconds when the page refreshed without clicking the Add button.
Does any one know the reason, and how to solve the problem?
Thanks in advance.
Dan

You said it yourself, you refresh your page each 3 seconds so each 3 seconds you do a request to your server where you show a messagedialog.

Button event handler

I have a Jbutton ...
When i click on it.. i want it to open up the chess game in a new window and start playing..
This is my codes..
//Event handler for the Jbutton
if(event.getSource() == Start)
chess frame=new chess();
frame.setSize(500,500);
frame.setVisible(true);
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
However.. when i click on it.. it gives me a java.lang.nullpointerException error...
the main application codes is actually an applet embedded into a frame...
Below is the class file which i wanted to link it..If it extends JFrame i can easily link it but it extends java.applet.Applet...
(public class chess extends java.applet.Applet implements MouseListener, MouseMotionListener,Runnable)
Is there a way to link it.?

You may not call JFrame methods on an Applet.
Also, Applet extends from Panel which is an AWT class, therefore, heavyweight vis–a–vis Swing which is lightweight. So you must load it into a Frame. If Chess were extending JApplet you could load it into a JFrame.
    //Event handler for the JButton
    if(event.getSource() == startButton)
        Chess applet = new Chess();
        final Frame f = new Frame();
        f.addWindowListener(new WindowAdapter()
            public void windowClosing(WindowEvent e)
                f.dispose();
        f.add(applet);
        f.setSize(500,500);
        f.setLocation(200,200);
        applet.init();
        applet.start();
        f.setVisible(true);
    }

JTable Custom Cell Event handling

Hi,
I have a column in JTable as image which is rendered by using custom cell renderer. I want to handle action event for the cell...
I tried adding actionPerformed event for the button using which the image is rendered but the event is not triggered....
Can you please tell me how to proceed with this
Thanks,
S.Anand

I'm assuming you want to know when the user has clicked on a particular cell in the table. If so, add a MouseListener to the table then implement a MouseListener or one of the Mouse...Adapter classes with the method:
public void mouseClicked(MouseEvent e)
    Point p = e.getPoint();
    int row = table.rowAtPoint(p);
    int col = table.columnAtPoint(p);
    // now do something according to the cell that was clicked
