Alternative for Combo-box

Hi,
Combo-BOx is not supported by Forms on web,so I would like to make combo-box my-
self .. I dont know how but I guess I can
do it with JAVA. Also I like to prepare it
exactly same like Oracle COMBO-BOX with
all functionality ..
Anybody have any IDEA pl.
give me respond or

Action event automatically triggered for combo box

Hi all,
I am facing a typical event handling problem for combo box in Swing(Using Net Beans 5.0, jdk 1.4.2)
While adding items to combo box it is firing action event twice instead of once irrespective of no. of items added to it.
For eg if there are 1 or more than 1 item added to combo box it is triggerring action event twice(one just after when first item is added and one again when rest all items are added)
and if there is no item then also it is triggering once.
Can you please help me out.
Thanks

post the SSCCE code, then only it is easy to find the problem

Enumeration binding for combo box - missing feature

Hi,
In our application, combo boxes are usually employed for similar purpose as radio button groups: provide the end-user with an exclusive, static list of choices.
Unfortunately, JUComboBoxBinding.createEnumerationBinding method does not seem to follow the same paradigm as JUButtonGroupBinding.createEnumerationBinding.
In fact, for JUButtonGroupBinding, one parameter is "AbstractButton[] buttons", which is used for display purposes (end-user descriptions of the choices), and another is "Object[] valueList", which is the list of values for the corresponding attribute (usually, the valid values in the database for the column).
Meanwhile, JUComboBoxBinding is only receiving one array parameter, "Object[] values", which is used both for display purposes and for database values... This approach is very restrictive, as long as we expect to display in the combo box a descriptive text for the coded value in the database (and localizable, as well!).
Is this a known bug, or am I the first one to have noticed it? Is there any schedule for making this feature available?
Thanks,
Adrian

I'm not sure where my last reply went, so another try.
Unfortunately, I have the same feeling as usual, that my posted messages are not carefully read...
The main issue was the comparison between JUComboBoxBinding and JUButtonGroupBinding, and my question was about the possible future availability of a feature. Nothing about this in the answer...
Could I have an aswer to my original message, please?JUButtonGroupBinding is a custom control provided by JClient and has an api to let a user 'provide' custom Button objects instead of the default 'RadioButton's that would get created if none is passed in. The fact that you could use that to perform LOV kind of indirection of displaying a value other than what's set is 'a side-effect' of the original intention.
FYI, we already implemented an extension to JUComboBoxBinding which is just doing what I was asking for. It is not complex at all:( I was only thinking that it might be useful also in standard...The 'standard' way of getting this behavior you're asking for is to create a programmatic VO as suggested above, with both display/update attribute values and bind it to the ComboBox as an LOV Binding. And yes you can certainly create custom controls extending Swing and use the existing bindings or 'extend' them as per an application need.

Adrian

Display Attribute for Combo Box List of Value

Hi all,
I am wondering that if even for JDeveloper 12c we need to keep doing this work around https://blogs.oracle.com/adf/entry/combo_lov_how_to_display in order to display a meaningful attribute?
Regards

You could, for example. store both of them (old value, along with new one) in the pageFlowScope. You can do that in the valueChangeListener (before calling popup), and use them in the dialog listener...

Why will this not work for combo box

I need to know why this will not work a combobox but it works for text fields. Isay ther is an error in the doc.createTextNode.
Please any help would be great.
Thanks
// Repeats for each Element in the User Configuration.
item = doc.createElement("COMPANY_NAME"); // Create element
item.appendChild( doc.createTextNode(SetupCompanyNameJText.getText()) );
UserConfig.appendChild( item ); // atach element to User Config element
item = doc.createElement("INTIALS"); // Create element
item.appendChild( doc.createTextNode(SetupIntialsjComboBox.getSelectedItem()) );
UserConfig.appendChild( item ); // atach element to User Config element
item = doc.createElement("FIRST_NAME"); // Create element
item.appendChild( doc.createTextNode(SetupFirstNamejText.getText()) );
UserConfig.appendChild( item );

when I do that I end up with the following
Error: #:300: class Configuration not found in class
any ideas
thanks

ArrayCollection for combo box - null vlaue

I have defined an ArrayCollection like this:
public var typename:ArrayCollection = new ArrayCollection(["Simple" , "Complex"]);
In mxml file,
the usage is,
<mx:ArrayCollection id = "sample">
<mx:Object dataField = "type" dataType = "Array" dataProvider = "{com.values.typename}" editable = true updatable = "true"/>
</mx:ArrayCollection>
In screen, i get the drop down with a null value. I want only two values dropped down , Simple and Complex.
Where does this null field come from??

1. your arrayCollection should be bindable:
[Bindable]
public var typename:ArrayCollection = new ArrayCollection(["Simple" , "Complex"]);
2. What is com.values? Is that a reference to a class? If you store typename in a class, you can do two things:
     a. Store it as a static var:
          public static var typename....
          and then reference it as MyClass.typename
     b. Store it in a singleton class and then reference it as MyClass.getInstance().typename
3. How do you populate your comboBox? Where is it in your code?

Plotting a combination chart with a combo box for selection

Hi:
I am a newbie using xcelcius and I need help on the following:-
I need to create a combination chart that plots 3 years data by month, and I need a combo box selection at the top that allows me to select user display for each difference region. I manage to create one that plots only 2008 data with a combo-box selection, but I have no idea how to do it for a combi chart in xcelcius. Any advise?

Hi Ning,
I assume your data are like this:
Region             Year     Jan     Feb     Mar
APJ             2006     $234.45     $310.34     $321.54
APJ             2007     $314.35     $319.12     $256.89
APJ             2008     $425.54     $354.34     $285.73
North Asia     2006     $534.64     $642.35     $484.64
North Asia     2007     $631.74     $654.13     $754.34
North Asia     2008     $754.31     $423.65     $634.32
South East Asia     2006     $536.42     $576.35     $525.42
South East Asia     2007     $426.78     $876.43     $643.75
South East Asia     2008     $634.87     $425.77     $732.43
If this, you can set the insertion type of combo box is "Filtered Rows", see steps:
1) For Combo Box, bind General > Labels to the Region column.
2) Set General > Data Insertion > Insertion Type is "Filtered Rows" (you can refer to following flash to see how "Filtered Rows" works).
3) Set its Source Data are Year, Jan, Feb, ... columns and Destination to blank cells.
4) Bind Chart to the destination data.
Now when you select APJ from Combo Box, it will insert all the rows of APJ data to the desitination cells which will be displayed in Chart.
Hope this can help!

Not a JSP issue. Look up styles, CSS, and dynamic HTML. They should help.

Determine the best width for ListCellRenderer - Multi-column combo box

Currently, I am having a multi column combo box. In order for the column to align properly during show popup, I use box layout to do so. However, the short coming for box layout is that, the size for each column is fixed. This makes me have a difficulty, when I have a long string to be displayed. The problem is shown through the following screen shoot.
http://i.imgur.com/4Nfc6.png
This is because in 2nd column,
1) All the 3 rows must be in same size so that they are aligned.
2) But 1st row and 2nd row cell renderer, do not know 3rd row is holding such a long string.
The code (2 files) to demo this problem is as follow. Is there any way the size of the cell will be adjusted automatically? Yet, all the row will be aligned properly.

Are these two lines intentionally or is it just a mismatch?
jLabel2.setMaximumSize(new java.awt.Dimension(100, 14));
jLabel2.setMinimumSize(new java.awt.Dimension(200, 14));
2) But 1st row and 2nd row cell renderer, do not know 3rd row is holding such a long string.There is only one cell renderer for all rows, so no need for the rows to know each other.
To calculate the exact maximum width of column two, you have to check each entry.
If you can do this BEFORE creating the combo, you could do this in a loop similar to this pseudo code
FontMetrics fm= jComboBox1.getFontMetrics(jComboBox1.getFont());
foreach (column2String) {
int length= fm.stringWidth(column2String);
if (length>max) max= length;
}Now you have a max value to dimension jLabel2 in your renderer.
If you don't fill your combo in one go, but rather at runtime, you have to check at each
jComboBox1.addItem(...)
whether the string for label2 is extending the current max, redefine max, and repaint the combo.
This second approach I haven't done so far, but that's how I would try.

CUIT is not giving name property value for VB combo boxes

Hi Everyone,
We are testing simple Vb6 controls using CUIT. Using CUIT we can get name property value of Vb6 button control. But for simple Vb6 combo box, CUIT is not showing name property value.
I want to add CUIT assertion for combo box name property value. how can I add ?
For more details please see the image
Regards,
Rajendar..

Hi Rajendar,
Do you record a coded UI test with the coded UI test builder? If so, which item did you record?
>>How can I get combobox.SelectedItem without identifying combo box?
It doesn't mean that we don't identify the control. Generally we use the unique property as the search property to find/capture the control.
Like this blog here:
http://blogs.msdn.com/b/visualstudioalm/archive/2012/02/01/guidelines-on-improving-performance-of-coded-ui-test-playback.aspx
SelectedItems versus
SelectedIndices property
For large number of items, it is preferable to use SelectedItems. SelectedIndices essentially does an Instance search internally, which is slower compared to unique automation property based search. Use SelectedIndices only when
the items don’t have unique Automation properties. And of course exercise caution over changes to the list content.
I think you could get a useful sample here:

How do I retrieve data from combo boxes?

The past weekend I spent my whole weekend trying to find this
out and gone through the top 10 pages on google trying all sorts of
things. I would be grateful for anyone who can help me.
I have 6 combo boxes in a booking form and I need to retrieve
the data when someone click submits which gets forwarded on to php
then my mailbox. They are called box1_cb, box2_cb.....box6_cb All
in the instance of: ComboBox - which I don't understand what that
does.
it does not seem to be retrieving any of the data. For each
combo box:
I have the the options people can choose form in "Labels" box
under "Paramaters", nothing for "Data", Row Count is 8 and nothing
for "Change Handler" which I don't know what it does.
Can anyone please provide some help with telling me what
"change handler" does, do I need the data for each combo box in the
"Labels" parameter as well as the "Data" box, what an instance does
(for combo boxes) and what I need to put in the actionscript for
the submit button as well as do i need to put code in the
actionscript for each combo box?
The options people can choose from in the combo boxes are
there when someone views the site.
Can anyone please help me..I would greatly appriciate it.
Thanks.

If your hard drive can be detected and shows up as a drive letter in my computer but you can't access your files,then you can recover your data off it with data recovery software easily.This way is the easiest and the most inexpensive way to recover your data.If you bring it to a computer repair shop that is available for data recovery servise,they will cost you $500-1000 or more.Hmm, a lot of money.
I managed to recover data from crashed hard drive with Tenorshare Data Recovery.If needed,you can download it and scan your hard drive for free to preview whether your data can be recovered.It will show you thumbnails for recoverable pictures.

Combo box popup width adjusting no longer work in 1.0.6_26-b03

Previously, I was able to adjusting combo box popup's width, by referring to the technique described in [http://tips4java.wordpress.com/2010/11/28/combo-box-popup/|http://tips4java.wordpress.com/2010/11/28/combo-box-popup/]. During that time, I was using 1.0.6_24-b07.
However, after I update my Java runtime to 1.0.6_26-b03, things broke.
Here is the screen shoot.

I had came across another workaround as stated here.
[http://www.jroller.com/santhosh/entry/make_jcombobox_popup_wide_enough|http://www.jroller.com/santhosh/entry/make_jcombobox_popup_wide_enough]
The popup's is having enough width to show all items. However, it is not perfect still, as the width is little too much. I still can see some extra space at the tailing of the list.
The workaround is as follow.
import javax.swing.*;
import java.awt.*;
import java.util.Vector;
// got this workaround from the following bug:

Combo Box in JTable

Is there a way to make one column in a JTable a ComboBox so that user can choose between 2-3 items?
Any code help would be appreciated.

Here are just some code snippets, sorry i didn't tidy them up.
//here is the initialization of the comboBox column and get data from db
public void initComboColumn(TableColumn col, String query) {
JComboBox comboBox = new JComboBox();
Vector columnResults = DatabaseUtilities.getComboResults(query, true);
try {
    if (! (columnResults.contains("R"))) {
      columnResults.addElement("R");
    if (! (columnResults.contains("N"))) {
      columnResults.addElement("N");
    if (! (columnResults.contains("B"))) {
      columnResults.addElement("B");
    comboBox.setModel(new ResultSetComboBoxModel(columnResults));
    col.setCellEditor(new DefaultCellEditor(comboBox));
    DefaultTableCellRenderer renderer =
        new DefaultTableCellRenderer();
    renderer.setToolTipText("Click for combo box & choose data type");
    col.setCellRenderer(renderer);
    //Set up tool tip for the sport column header.
    TableCellRenderer headerRenderer = col.getHeaderRenderer();
    if (headerRenderer instanceof DefaultTableCellRenderer) {
      ( (DefaultTableCellRenderer) headerRenderer).setToolTipText(
          "Click to see a list of choices");
catch (Exception e) {
    e.printStackTrace();
//ResultSetComboBoxModel
import javax.swing.*;
import java.sql.*;
import java.util.Vector;
public class ResultSetComboBoxModel extends ResultSetListModel
    implements ComboBoxModel
    protected Object selected = null;
    public ResultSetComboBoxModel(Vector columnResults) throws Exception {
        super(columnResults);
    public Object getSelectedItem() {
      return selected;
    public void setSelectedItem(Object o) {
        if(o==null)
          selected = o;
        else{
          String value = (String) o;
          selected = (Object)(value.substring(0,value.lastIndexOf(" // ")));
//ResultSetListModel
import javax.swing.*;
import java.util.*;
import java.sql.*;
public class ResultSetListModel extends AbstractListModel {
    List values = new ArrayList();
    public ResultSetListModel(Vector columnResults) throws Exception {
      for(Iterator item = columnResults.iterator();item.hasNext();){
        String[] value = (String[])item.next();
        values.add(value[0] + " // " + value[1]);
    public int getSize() {
        return values.size();
    public Object getElementAt(int index) {
      return values.get(index);
}Hope this helps.

Using Combo box at the backend

Hi,
I am using combo box at the backend to filter rows to a particular destination.
The problem is the labels are going to populate at the runtime and the selection of item in combo box is also going to populate at the run time. I have an icon which inserts eg: country in a cell, then this cells is used by combo box as a item selection(label) to filter rows from source. But unfortunately the comb box is not selecting any value i.e no item is selected dynamically. But if i manually drill down it is working but the label is not changing dynamically based on the changes in label by icon.
For eg my data:
Country and profit populate at run time
Country          Profit
India               5000
Germany        4000
Now i have icon which selects country (hard coded in excel) upon clicking the mouse on it and inserts in A1 suppose the value hardcoded is "India". Now this A1 is used as a "selected item" for combo box. the source to combo box is the above country and profit which populates at run time.
Now when i execute the dashboard. The value is inserted in A1 after clicking the icon but it is not picked up by combo box as "item selected" and hence combo box does not filter any data.
Can any pls help.
Thank you. I will award full points for correct solution.

Hi Monammed,
The said functionality should work. Please check your logic one more time. Also, try using some spreadsheet components mapped to the cells in question and understand how the data is flowing during run-time. This will help you test things. Delete spreadsheets when you are done with identifying the issue.
Lets check the combo box mapping one more time : Map the source of the combo to the entire range; labels in the combo box ONLY to the country column in the source range(typically this may be the left most column in the range); selected item should be mapped to the cell that has the destination for the icon and the type for default selection may be dynamic. Well, if there is any hard-coding of values involved anywhere, do check the spellings and other trivial things.
Do let me know if this was helpful and if you need any more help.
Thanks,
Prasanna
