New entry in editable JComboBox

I have been looking through the forum to try and find an answer to this, but I can only find queries about positioning in an editable combo box. what i want to do is for a person to be able to select an item from a combo box, or enter a new item. is this possible?

JComboBox myComboBox = new JComboBox();
myComboBox.setEditable(true);
myComboBox.addItem("Hello");
myComboBox.addItem("There");
myComboBox.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e) {
if (myComboBox.getSelectedIndex()==-1) {
myComboBox.addItem(myComboBox.getSelectedItem());
});

And make a provision to delete wrong entries, or you'll end up with all the typos stored separately.
I speak from experience. I actually have such a combo in several of my VFP applications (not in Java though)

Editable JCombobox cell editor length limit

Hi All,
I have an editable JCombobox as a celleditor to one of the column in JTable, How do I limit the characters in the cell editor?
Thanks

A JComboBox uses a JTextField as it's cell editor. You should read up on how you would do this for a normal JTextField by using a custom Document:
http://java.sun.com/docs/books/tutorial/uiswing/components/generaltext.html
Here's an example using JComboBox. I haven't tried it in a JTable but I assume it should work.

          String[] items = { "one", "two", "three", "four" };
          JComboBox list = new JComboBox( items );

JTable with editable JComboBoxes

For some reason once I added editable JComboBoxes to a JTable I can no longer tab among the fields in the table. If I just select a cell, I can tab to the other cells in that row, and then to proceeding rows as I reach the end of each. However if I double click the cell and enter data or select from the combobox. I no longer can tab to the next cell. At that point once I do hit tab, I am taken to the next table. Not the next cell in the row, or the next row in the current table.
I have tried messing with a bunch of listeners, but I am not using the right listener on the right object? What listerner and object should the listener belong to? Table, model, cell editor, combobox, jpanel, jframe ? I hope this is not to vague.

Well I am starting to think it's an implementation issue. Like I am not doing it how I should. I am basically doing
JComboBox jcb = new JComboBox();
jcb.setEditable(true);
column.setCellEditor(new DefaultCellEditor(jcb));
When I think I should be inheriting, and creating my own editor and/or renderer? Now my combobox vars are globally available in the class, so I can set and clear their contents. It does not matter that each row in the table has the same content in the combo boxes, that's basically what I want. User to be able to select an existing entry or make a new one.
What I am trying to do is on tables have a drop down box that shows up when a user types a matching entry. If no entry matches, no popup box. If entry matches, box pops up and shows possible entries starting with what they are typing. Like code completion in IDE's like Netbeans. However I am doing this in a table. I thought a JComboBox would be a good widget to start with?

How can I use a FocusEvent to distinguish among editable JComboBoxes?

Hi,
I have a Frame with multiple editable JComboBoxes, but I am at a loss as to how to sort them out in the focusGained() method.
It is easy when they are not editable, because the FocusEvent getSource() Method returns the box that fired the event. That lets me read an instance variable that is set differently for each box.
But with editable boxes, the FocusEvent is not fired by the box. It is fired by a Component object returned by getEditor().getEditorComponent(). So far I cannot find a way to query that object to find the box it it tied to. (I hope this isn't going to be painfully embarassing.).
Anyway, the code below produces a frame with four vertical components: a JTextField (textField), a NON-Editable JComboBox (comboBox1) and two Editable JComboBoxes (comboBox2 & comboBox3).
This is the command screen produced by :
- Running the class
- Then tabbing through all the components to return to the text field.
I am not sure why, but it gives the last component added the foucus on startup.Focus Gained - Begin: *****
   This is the comboBox that Is Not Editable
Focus Gained - End: *******
Focus Gained - Begin: *****
   This Is The TextField
Focus Gained - End: *******
Focus Gained - Begin: *****
   Class: class javax.swing.plaf.metal.MetalComboBoxEditor$1
   Name: javax.swing.plaf.metal.MetalComboBoxEditor$1
Focus Gained - End: *******
Focus Gained - Begin: *****
   Class: class javax.swing.plaf.metal.MetalComboBoxEditor$1
   Name: javax.swing.plaf.metal.MetalComboBoxEditor$1
Focus Gained - End: *******
Focus Gained - Begin: *****
   This is the comboBox that Is Not Editable
Focus Gained - End: *******
Focus Gained - Begin: *****
   This Is The TextField
Focus Gained - End: *******As you can see, the FocusEvent source for both editable boxes is a MetalComboBoxEditor. Both have identical names.
Can anyone help me get from there back to the actual combo box so I can read the instance variable to see which one fired the event?
The (painfully tedious and inelegant ) code that produced the above output is:import java.awt.*;
import java.awt.event.*;
import java.util.*;

the thing is that I can create and add a new entry in openLDAP from the console and it works.
and here is how I proceed
I create a text file: new.txt
dn:cn=Hamido Saddo,ou=People,o=JNDITutorial,dc=img,dc=org
cn:Hamido Saddo
mail:[email protected]
telephonenumber:3838393038703
sn:hamdio
objectclass:top
objectclass:person
objectclass:organizationalPerson
objectclass:inetOrgPersonand i use this command to add the entry:
ldapadd -D "cn=ldap_admin,O=JNDITutorial,dc=img,dc=org" -W -f new.txtand everything works, i get no errors.
does anyone has a clue maybe???

You must have an IMAP email account in order to add additional folders on the iPad mail app.
If you go to your email account in the Mail app and look at the window where your inbox, trash folder and sent folder are - if there is an Edit button at the top of the window - tap that and then tap Add Mailbox at the bottom.
If the Edit button is not there - you cannot create folders on the iPad. Your email account is not IMAP. Only IMAP email accounts can create folders on the iPad. Any folders that you would already have in an IMAP account would sync to the device as well.

Not able to create new entry in RSADMIN Table

Hi All,
        I am going thru the OSS note 1275837 (Note 1275837 - PrecServer: process based load distribution (ABAP part)), as it recommends
        add the entry "BWPREC_USE_NEW_LOAD" with value "X" in table "RSADMIN"
      When I check in SE11 and SE16 there is no option to create button for above entry in table RSADMIN.
      Please advise for any help to create above entry.
Thanks

Hi
Goto SM30 - Table Maintanance Generator and enter the table name and click on button maintain ,it will show the error message
"The maintenance dialog for RSADMIN is incomplete or not defined" because the table maintenance is not allowed manually.
First Option
When you double click the error message a performance assistant screen will open in that you can see Procedure
"Generate the required maintenance dialog" click on that and try to maintain the table using Access Key, as i dont have access key i have not tried this option.
Second Option
You can write an SE38 program with an insert statement.
TABLES rsadmin.
DATA: wa TYPE rsadmin.
wa-object = 'object name'.
wa-value = 'X'.
INSERT into rsadmin values wa.
Thanks

Unable to create new entry in table that has no primary key

Hi
I have a table which is required to have no primary key (except mandt). After i generate table maintanance, when I go to create new entries, the table control to enter the new values does not appear. When I click on edit->new entries, it goes back to the fields tab of the table. Same when i check through SM30.
If i maintain atleast one primary key, I am able to get the table control in new entries screen. However the requirement permits no primary keys except mandt. How can this be resolved?
Thanks
NM

Hi,
THE PROBLEM WITH UR TABLE IS
YOU HAD DECLARED MANDT AS THE PRIMARY KEY AND THERE IS NO OTHER KEY IN UR TABLE
iT'S NOT ALLOWING YOU TO ADD NEW ENTRIES BECAUSE MANDT IS THE ONLY PRIMARY KEY IN YOUR TABLE AND IT WILL HAVE A DEFAULT VALUE BASED ON THE CLIENT. SO IT'S NOT SHOWING YOU THE CREATE NEW ENTRIES OPTION.
SO TRY TO PUT ONE MORE FIELD AS THE PRIMARY KEY SO THAT YOUR PROBLEM WILL SOLVE VERY EASILY ALSO MAKE SURE THAT TABLE IS ACTIVATED.
REVERT IF U NEED SOME MORE HELP
Thanks &Regards.

Hi Alok,
Hope this steps - code will help you to resolve this issue.
1. Create A Group for your table control. In Screen Painter.
2. Write Screen modification routine for the same
it can be like this..
MODULE status_0100 OUTPUT.
SET PF-STATUS 'SCREEN_100'.
LOOP AT SCREEN.
    IF screen-group1 = 'MOD'.
      IF flag = ' '.
        screen-input = '0'.
      ELSEIF flag = 'X'.
        screen-input = '1'.
      ENDIF.
      MODIFY SCREEN.
    ENDIF.
ENDLOOP.
ENDMODULE.
3. This will disable the display of the Fields in TABLE Control.
4. in the PBO loop of the table control. Identify the lines which u want to keep active.
Hope this will help

Blank values for editable JComboBox

Hello,
I have a editable JComboBox that the user can erase its current value and if they simple change focus (like click on a text field on the same panel) the combo box is left blank. i would like to have it so that if the user leaves focus of the box and its blank that current value goes back to what it was before they erased it.
Many thanks,
Jonathan

Editable JComboBox in a JTable

I posted my problem into the "Java Essentials/Java programming" forum but it would be much better if I'd posted it here into the swing theme :).

editable JComboBox in a JTable
Oct 21, 2006 1:32 PM
Click to email this message
Hello!
Yesterday I posted a problem, solved it and there's another one, referring the same theme.
So it's about a editable JComboBox with autocomplete function. The combo is a JTables cellEditors component. So it's in a table. So when the user presses the enter key to select an item from the JComboBox drop down menu, I can't get which item is it, not even which index has the item in the list. If for exemple the JComboBox isn't in a table but is added on a JPanel, it works fine. So I want to get the selectedItem in the actionPerformed method implemented in the combo box. I always get null instead of the item.
Oh... if user picks up some item in the JComboBox-s list with the mouse, it's working fine but I want that it could be picked up with the enter key.
Any solutions appreciated!
Thanks, Tilen

Click to email this message
I suggest that you distill your current code into a simple class which has the following attributes:
1. It can be copied and pasted and will compile straight out.
2. It has a main method which brings up a simple example frame.
3. It's no more than 50 lines long.
4. It demonstrates accurately what you've currently got working.
Without that it's hard to know exactly what you're currently doing, and requires a significant investment of time for someone who hasn't already solved this problem before to attempt to help. I'm not saying that you won't get help if you don't post a simple demo class, but it will significantly improve your chances.

Okay ... I'll write the code in short format:
class acJComboBox extends JComboBox {
public acJComboBox() {
    this.setEditable(true);
    this.setSelectedItem("");
    this.getEditor().getEditorComponent().addKeyListener(new KeyAdapter() { public void keyReleased(KeyEvent e) {
     // ... code code code
     // that's tricky ... the method getSelectedItem() always returns null - remember; the acJComboBox is in a JTable!
     if (e.getKeyCode() == 10 && new String((String)getEditor().getItem()).length() != 0) { getEditor().setItem(getSelectedItem()); }
}And something more ... adding the acJComboBox into the JTable:
TableColumn column = someTable.getColumn(0);
column.setCellEditor(new DefaultCellEditor(new acJComboBox());
So if the user presses the enter key to pick up an item in the combo box drop down menu, it should set the editors item to the selected item from the drop down menu (
getEditor().setItem(getSelectedItem());
When the acJComboBox is on a usual JPanel, it does fine, but if it's in the JTable, it doesn't (getSelectedItem() always returns null).
Hope I described the problem well now ;).

Okay look ... I couldn't write a shorter code just for an example. I thought that my problem could be understoodable just in mind. However ... type in the first combo box the letter "i" and then select some item from the list with pressing the enter key. Do the same in the 2nd combo box who's in the JTable ... the user just can't select that way if the same combo is in the JTable. Why? Thanks alot for future help!

Table Maintenance Object - Hide New Entries button

Hello,
Does anyone know how to hide the "New Entries" button in a table maintenance object?
I want to allow editing of the table, but I don't want to allow new lines to be inserted.
The generated screens do not have a gui status. I guess the gui status is part of SM30 and not part of the maintnenance object itself.
Thanks
Doug

Distribute new entries against existing reference data, Integrated Planning

Dear Experts,
Within IP, I struggle with how to distribute new entries against existing reference data.
Example:
Reference data:
Product   /   Customer   /   amount
P1               C1                  100
P1               C2                  150
P2               C2                  120
P2               C3                  100
New data:(data entered on product level, therefore not assigd to customer yet)
P3          #                    150
How can I distribute product P3 to Customers with reference to the data on product P1 ?
Many thanks,
Erik Pos

Hi Hyma,
This documentation indeed indicates that you can use other characteristic values in the parameter group to be used for reference, good news !, but this is based on SAP-BPS ?
The SAP-BW IP documentationn does not include this information can you confirm this solution works for Integrated Planning using the conditions within the function distribute with reference data ?
Many thanks,

Can JOptionPane produce an editable JComboBox?

Can I use JOptionPane for an input dialog component with a data input area represented by an editable JComboBox ?
For example :
JOptionPane.showInputDialog( parent,
� How Much?�,
�This is the title�,
JOptionPane.QUESTION_MESSAGE,
null,
new Object[]
{ � �, �un peu�,�beaucoup�,�passionnement�},
�passionnement�);
This one statement produces the input dialog I want, except that it does not allow an input such as �pas du tout� which is not in the list of selections.
Does any one knows if somehow I could get to this JComboxBox and make it editable? (still using JOptionPane of course)?
Thank you to any one who can answer me.

Hi,
You could use the JOptionPane.showMessageDialog() in the following way:
JComboBox comboBox = //Make your own JComboBox here
Object[] message = new Object[] {
"Make your choice:",
comboBox
JOptionPane.showMessageDialog(parent, message);
In this way you are able to add every Component to your message dialog you want to.
Hope that helps, Mathias
