SetText in LostFocus event

Hi,
I'm trying to set the text in a textbox used as a table cell editor when it loses focus. Unfortunately though the .setText() command gets ignored although it does get run. If the textBox is not used as a cellEditor it works fine.
Does anyone know what might be going on here?
Simon

Once the focus is lost, I am seeing what the renderer displays rather than the contents of the text box directly but I was thinking that the underlying data should have been updated, so the renderer would show the last value entered in the text box.
I thought the editing may have been cancelled, but our code that manually stopped the editing wasn't being called, but it seems that the table was doing this itself before the text box lost the focus.
I now call the lost_focus code from the CellEditor in the method 'getCellEditorValue' which returns the text from the text box to the table, and this works fine.

How can i catch the gotfocus and lostfocus events

Hi Dear;
i tried to catch the gotfocus and lostfocus events, but i can't.
in the same code i can catch the onclick events.
is there any special code for the gotfocus and lostfocus events?
regards;

Danny;
Whenever I have an issue such as this I fire up the event logger and it will show you exactly which events you can put your hooks into. If you are not using it you should really check it out. Will save you tons of time.

Table cell lostfocus event.

I have a table column where user inputs some amount for calculation.
I would like to call the calculation function everytime the value is entered.
What's the best way to do so?
I am thinking about ading lostfocus event to that column, but can anyone give me some direction about how to do add event to table column? (I defined my own TableModel)
thank you.

override the method setValueAt in your own-defined TableModel, like this
public void setValueAt(Object value, int row, int col){
          if (value != null) {
               fireTableCellUpdated(row, col);
               if (!((String)value).trim().equals("")) {
                    //save data
                    savePC((String)value, row);
     }

How to handle LostFocus event for TextField in J2ME?

Hi:
I want to handle LostFocus event for TextField in J2ME.
So can anybody help me.....
Thank You

MIDP API does not have LostFocus event.
You can try setting ItemStateListener for the TextField ([if needed, click here for details|http://java.sun.com/javame/reference/apis/jsr118/javax/microedition/lcdui/ItemStateListener.html]). API requires that +"...For implementations that have the concept of an input focus, the listener should be called no later than when the focus moves away from an item whose state has been changed. The listener should be called only if the item's value has actually been changed...."+

LostFocus Event

Hi all,
I am newbie to swings. I am having a problem when validating a JTextField for only characters, i am able to validate for characters and displaying a proper error message using JOptionPane.
After the error message is displayed i am again keeping the focus back on to the same JTextField, here the error message is displaying repeatively for 4 to 5 times. i am pasting the code below.
private void txtdaFocusLost(java.awt.event.FocusEvent evt) {
        if(validatenumeric(txtda.getText())) {
            txtda.setText("");
            txtda.requestFocus();
    }    and i am writing the code for validatenumeric below:
public boolean validatenumeric(String num) {
        if(num.length()!=0)
            try {
                Integer.parseInt(num);
            } catch(Exception e){
                JOptionPane.showMessageDialog(null, "Enter data in Numeric Format", "Input Error", JOptionPane.ERROR_MESSAGE);
                return true;
        return false;
    }

Quit cluttering the forum, you posted this same question 4 minutes ago.
What is SwingS? I thought this was the Swing forum.
Use a JFormattedTextField, or add an InputVerifier to the text field.

Change Event

Hi
First I wanna say that i'm getting great support from this forum here -> Thanks!
I've tried to catch change events of an editText-Control in the orderline - grid.
It works when enter values manually but doesn't work when a default value get set (eg. after selecting an item).
It's important that I get every changed/new value because I'll do some calculations with the current sum of those columns.
For now I rely on LostFocus events on different columns just to make sure that i catch changes in one column that maybe doesn't get/lost Focus.
And what about an rowChanged Event? Could be useful too.
Greetings
Phil

Hi all,
SBO fires VALIDATE event more than once and I use a trick:
Public Instances as Integer
 If pVal.FormType = 140 Then
 If pVal.ItemUID = "38" Then
 If pVal.ColUID = "1" And pVal.EventType = SAPbouiCOM.BoEventTypes.et_VALIDATE And pVal.Before_Action = False Then
 oForm = SBO_Application.Forms.GetFormByTypeAndCount(140, pVal.FormTypeCount)
 oMatrix = oForm.Items.Item("38").Specific
 GetIskaot(oForm, oMatrix, pVal.Row)
 End If
 End If
 End If
 Private Sub GetIskaot(ByRef oForm As SAPbouiCOM.Form, ByRef oMatrix As SAPbouiCOM.Matrix, ByVal NRow As Integer)
 If Instances <> 0 Then Exit Sub
 Instances = 1
 Instances = 0
 End Sub
It's a real example that works fine
Regards,
Mark

LostFocus problem

Hi all, i'm having a problem with the lostFocus Event.

JTextField does not visualize the text!

Hello everybody,
i have a problem with JtextFields.
I have a Jtable with a ColumnHeader that contains a Button, a combobox and a JTextField.
Normally i have 3 columns. When i try to move from a textfield to another textfield i can write in this one but the text is not visualized and i do not se the cursor in it.
If i click a second time in the textfield, then the text gets visible.
Here after the code of my UIText which extends JTextField.

I run the program using Eclipse; run as> Java applet
and in runs perfectly well. I then tried running it using internet explorer and firefox, but only a gray box appeared and the browser says "applet notinited" and "Loading Java Applet Failed.."
what did i do wrong? any help is really appreciated.. thanks

thank God i already found the cause of the problem..
it's because the application has an ImageIcon which links to a local jpeg file, so perhaps security restriction on the browser doesn't allow my applet to access local file, that's why it fails to load.
either using signed applet (not tested) or removing the picture solved my problem.
thanks anyway :)

Is this a Bug?: FocusListener called twice

Hey all,
Im having this problem since realease 1.4.2_04.
Folks, try this code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class FocusTest {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Focus test");
        final JTextField field1 = new JTextField("Test1");
        final JTextField field2 = new JTextField("Test2");
        field1.addFocusListener(new FocusAdapter(){
            public void focusGained(FocusEvent e){}
            public void focusLost(FocusEvent e){
                if( !e.isTemporary() ){
                    System.out.println("ID: " + e.getID());
                    JOptionPane.showMessageDialog(null, "Focus lost in 1");
                    field1.requestFocus();
        frame.getContentPane().add(field1, BorderLayout.WEST);
        frame.getContentPane().add(field2, BorderLayout.CENTER);
        frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        frame.setBounds(0,0,200,300);
        frame.show();
} The problem is: when TF1 looses its focus, and is validated, then i force the focus to keep on TF1 by calling TF1.requestFocus(), somehow the event focusLsot is called twice for my TF.
If i do not requestFocus() it work but I must force the focus on TF1.
Im going nuts. Does anyonw apear to have this problems?? In old realeses, the same code work perfect. until 1.4.2 beta.
Tks
Bruno

Hello all!
I found out that somehow JDialog with requestfocus after, fires twice the lostFocus event. I dont know why. I opened a bug report so they can figure it out why is happaning.
Tks folks!

How to do addition of two columns cells in Matrix.

Hi All,
I tried following code on LostFocus event of Mtrix. I want to do addition of two columns cells of matrix and addtion display in third column. I tried the following code but in this I am getting the column value and when i enterd any value in columns cells it disappear when i move to next column cells.
Can anybody suggest me how to do it ?
Dim i As Integer
            Dim v1, v2 As String
            matrix.Columns.Item("V_4").DataBind.SetBound(True, "", "matrixds")
            If pVal.ColUID = "V_4" Then
                For i = 0 To matrix.RowCount - 1
                    v1 = matrix.Columns.Item("V_5").Cells.Item(i + 1).Specific.Value
                    v2 = matrix.Columns.Item("V_4").Cells.Item(i + 1).Specific.Value
                    Dim v3 As Integer = CInt(v1) + CInt(v2)
                    matrix.Columns.Item("V_3").Cells.Item(i + 1).Specific.Value = v3.ToString()
                Next
            End If
Thanks and Regards,

Hi,
u bind all the columns to the datasource in the matrix.then the value does not disappear.
Change ur code as follows:
Use the databind in formload
matrix.Columns.Item("V_4").DataBind.SetBound(True, "", "matrixds1")
matrix.Columns.Item("V_5").DataBind.SetBound(True, "", "matrixds2")
matrix.Columns.Item("V_3").DataBind.SetBound(True, "", "matrixds3")
Dim v1, v2 As sapbouicom.edittext
If pVal.ColUID = "V_4" Then
v1 = matrix.Columns.Item("V_5").Cells.Item(pVal.row).Specific
v2 = matrix.Columns.Item("V_4").Cells.Item(pVal.row).Specific
v3= matrix.Columns.Item("V_3").Cells.Item(pVal.row).Specific
v3.Value = v1 .Value + v2.Value
End If
Kind Regards

Setting Focus In Textarea

Ok,
I have a java program I've bundled into a jar and then packaged into a Win32 executable. I have windows associate a particular filetype (.wri) to my program.
When I click a .wri file and open it, it loads data to a textarea. Now when I scroll down the textarea and finally click in the textarea, it resets me to the top of the textarea. Now, if I open the executable first, then go through the program to open a .wri file, I can scroll down to the bottom of the textarea, click in the textarea and I do not get reset to the beginning. I need a way to prevent the resetting of the textarea. I've tried using some of the Window methods for setting Focus, but none seem to work. Any ideas why this is happening via the one way and not the other. I'm open to any ideas. This known bug frustrates many because the .wri files being opened have over 1000 lines of text. Thanks in advance!

i think yu can use setFocus by using lostFocus event.
use Focuslost()

Campus store program,help!

Hi Folks,
I have a probem with the following code. I am new to Java Programmimg. Can anybody help me please!
This application launches a window where the sales person can enter the items purchased. At the click of Next Item( b1), the screen is cleared to enter the next item and the transaction is processed. when receipt i(b2)s clicked, the details of the transactions are displayed. When summary button is clicked(b3) the details of the day's total transactions are displays. I have the following problems.
The title of the receipt is not displayed once the receipt textarea is cleared, but the transaction is displayed. I also stored the cost in a variable called Tcost (Tcost = Tcost + cost). I initilized Tcost = 0.0 It either displays the cost or 0.0 value but not the total cost. I am able to display the summary but when i click the 2nd time, it displays twice.
How do I calculate the total tax for the summary report and Cost and tax in receipt?
Please help!
Thanks.

Using DragEvents between different JFXPanels

Hi. I'm trying to set up a drag-and-drop function in my application that should transfer some data on a successful drag-and-drop completion. I'm following the examples given here:
Drag-and-Drop Feature in JavaFX Applications | JavaFX 2 Tutorials and Documentation
The event handler code for my source and target objects are exact copies of the source.setOnDragDetected and target.setOnDragOver / target.setOnDragDropped provided in the above example. I am putting a simple String into the DragBoard with a call to putString on the source event handler.
The drag and drop is initiated successfully (source event handler fires and puts the text in the DragBoard as per the example), but upon receving the DragEvent in the target event handler, it is not the same DragBoard - this one is simply empty. A call to DragBoard.getString() on the target DragEvent returns null.
The example works fine, with exactly the same code - line for line. What is different in my application is that both the source and the target nodes exist within separate JFXPanels. I have confirmed that both event handlers fire on the same thread, so it is not a threading issue either.
I'm drawing a blank here and am starting to think that embedding the scene in a JFXPanel somehow screws up the drag and drop data transfer via DragBoard. Can anybody clarify a bit around this issue for me? Thanks.

Just running some simple tests, the different JFXPanels do indeed appear to have different dragboards. One workaround is to use a JavaFX Property (or some other mutable wrapper for your data) to store the value being dragged.
