SetSelectedIndex() problem
I have a question on setSelectedIndex() for a combobox. First, can you use a attribute to set the index, like this:
cmbboxMapProjectionName.setSelectedIndex("infobus:/oracle/sessionInfo1/DISTINCT_MAP_PROJECTION_NAME/Id");
If you can...why am I getting the error...
D:\java_projects\MetadataBrowserTool\Main.java
Error: (1310) method setSelectedIndex(java.lang.String) not found in class oracle.dacf.control.swing.ComboBoxControl.
Thanks
The parameter for this method is an "int", not a "String". The error is correct - there is no method matching your signature.

PROBLEM : SetSelectedIndex with MultiColumn JComboBox
Hello,
I've got a problem with my MultiColumn (2 Column) JComboBox.
I had use in my ListCellRenderer a panel wich contains 2 labels (One for the code and another for the description of my item).
Everything work very well, except the "SetSelectedIndex" and "SetSelectedItem", when i do that the label2 appears over the label1...and i obtains some very strang things....
Is there anybody who got the solution or who got the same problem?
Thx for the futur response.
PS: I'm sorry for my bad english and my bad explanations, I'm french...Here is an example of a combo box with 2 columns using a JPanel implementing ListCellRenderer. Note that there are other ways to get appropriate background and foreground colors, but this is just a quick sample:
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.net.*;
import java.io.*;
import javax.swing.*;
import javax.swing.event.*;
public class Test extends JFrame
public static void main(String[] args)
new Test();
public Test()
Container c = getContentPane();
c.setLayout(new BorderLayout());
c.setBackground(Color.gray);
Item[] items = {
new Item("Item 1", "Value 1"),
new Item("Item 2", "Value 2"),
new Item("Item 3", "Value 3"),
new Item("Item 4", "Value 4")
JComboBox jcb = new JComboBox(items);
jcb.setPreferredSize(new Dimension(24, 24));
jcb.setRenderer(new ItemRenderer());
c.add(jcb, BorderLayout.NORTH);
setSize(200, 100);
setLocationRelativeTo(null);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setVisible(true);
// The items to display in the combobox...
class Item
String itemName = "";
String itemValue = "";
public Item(String name, String value)
itemName = name;
itemValue = value;
// The combobox's renderer...
class ItemRenderer extends JPanel implements ListCellRenderer
private JLabel nameLabel = new JLabel(" ");
private JLabel valueLabel = new JLabel(" ");
public ItemRenderer()
setOpaque(true);
setLayout(new GridLayout(1, 2));
add(nameLabel);
add(valueLabel);
public Component getListCellRendererComponent(
JList list,
Object value,
int index,
boolean isSelected,
boolean cellHasFocus )
nameLabel.setText( ((Item)value).itemName );
valueLabel.setText( ((Item)value).itemValue );
if (isSelected)
setBackground(Color.black);
nameLabel.setForeground(Color.white);
valueLabel.setForeground(Color.white);
else
setBackground(Color.white);
nameLabel.setForeground(Color.black);
valueLabel.setForeground(Color.black);
return this;
}I'm not sure, but the key to your problem may be with the opacity of your renderer. Let us know what you come up with. Cheers,

Problems with linked ComboBoxes
Hi everyone, and thanks to those who will reply
It's been 3 days since i'm having the same problem :
I have 2 comboboxes in a JPanel, and the things to be displayed in the second one depends on the first (for example selecting 'Hewlett-Packard' in the first combo box display all HP model in the second one)
When i select a item in the first combobox, an actionPerformed is fired, and i can populate the second combobox. Unfortunately, the combobox disappear in my panel, but if i click on the place where it used to be, the popup list display correctly... !
I just want to know hox can i make it visible anyway. I've tried combobox2.repaint() method within the actionperformed method (combobox2 is the name of my second combo box as you've guessed), but it doesnt work...
Something else too : in my first list, if i select another vendor, the list in the second is not removed, but the list of workstation of the second-select manufacturer is appended... I've tried here the combobox2.removeall() method, but here again, no results....
this is my code :

I've removed all the things I found useless, but maybe i've removed too much ;-) I hope that this code is enough.
Thanks for your help (can you send a copy of your answers at : [email protected] - if you're too lazy to do this that's not a matter, but i don't know how i can find my post in all these posts... so that'd be cool ;-)Thanks Martin
that makes sense now was driving me mad as I couldnt find anything saying it wasnt supported, makes sense seeing as its a flash server. Annoyning thing was it was playing in the content viewer locally when I previewd the folio you would think that would not be the case if it was not supported. Im going to try the rtmp links in a player in a web page and view it on the ipad out of curiosity and ill let you know. Out of interest have you done anyting with imported html into indesign as part of your folios ? I havent as yet but am curious to know how it holds up ?
Thanks again

Problem with Listeners/ requestFocus()
Hello,
I am new to Java (started learning two months back), There is a problem with the requestFocus() in the focusListener. The program does not return the focus to the object indicated in the requestFocus but it shows multiple cusors!!
The faculity at the institute where I am learning could not rectify the error.
Is the error because of the myMethod() which I am using. I had made this method to prove to my professor that we can reduce the code drastically while using the gridbaglayout.

// end of code.Would it not be acceptable to check that each field has a value when Submit is pressed. If a field is found with no data then display the error message and return the focus to the empty field. This would solve the multiple cursors problem as you would not need any focusLost handler code.
If this is entirely out of the question then you will have to override some of the FocusManager methods to prevent the JVM from handling focus for you :
FocusManager.setCurrentManager(new DefaultFocusManager() {
// Override FocusManager methods here.

Problem with focus border and ListCellRenderer in custom listbox
I have a bug in some code that I adapted from another posting on this board -- basically what I've done is I have a class that implements a custom "key/value" mapping listbox in which each list item/cell is actually a JPanel consisting of 3 JLabels: the first label is the "key", the second is a fixed "==>" mapping string, and the 3rd is the value to which "key" is mapped.
The code works fine as long as the list cell doesn't have the focus. When it does, it draws a border rectangle to indicate focus, but if the listbox needs to scroll horizontally to display all the text, part of the text gets cut off (i.e. "sometex..." where "sometext" should be displayed).
The ListCellRenderer creates a Gridlayout to lay out the 3 labels in the cell's JPanel.
What can I do to remedy this situation? I'm not sure what I'd need to do in terms of setting the size of the panel so that all the text gets displayed OK within the listbox. Or if there's something else I can do to fix this. The code and a main() to run the code are provided below. To reproduce the problem, click the Add Left and Add Right buttons to add a "mapping" -- when it doesn't have focus, everything displays fine, but when you give it focus, note the text on the right label gets cut off.

Problem in refreshing the combo box on selection of an item in another comb
I have a situation where values to be displayed in 2nd combo box depends on the selection of an item from the 1st combo box.
Problem observed:
The 2nd combo box is not getting refreshed if the selected item from the 1st combo box has mapping to more than 10 items.
for ex:
A - AA, AB, AC, AD, AE, AF
B - BA, BB, BC, BD, BE, BF, BG, BH, BI, BJ, BK, BL, BM, BN, BO, BP
C - CA, CB, CC
D - DA, DB, DC, DD
1st combo box list:
A
B
C
D
2nd combo box list:
If the value selected from the first combo box is A, C, or D then 2nd combo box refreshes with repective values. But when the value selected is B, then 2nd combo box is not getting refreshed with respective values.
Combo Model for 1st combo box:
public class proCLMLossTypeComboModel implements javax.swing.ComboBoxModel

jBtnSave.setNextFocusabl &nbsthe very simple strategy to do is to call removeAllItems() method for the 2nd combox box and then insert the contents. this is because the validate() method is not repeatedly called and so the contents are not updated immediately.

Who can help me :)--a problem with java program(reset problem in java )
I do not know how to make the button reset,my program only could reset diagram but button.If any one who could help me to solve this problem.The problem is When the reset button is pressed, the image should immediately revert to the black square, and the 4 widgets listed above should show values that
correspond to the black square.The code like this,first one is shapes:

// repaint DrawPanel
public void draw (){
if(showStatus == true)
repaint();
}If any kind people who can help me.
many thanks to you!4 widgets???
maybe this is what you mean.
add this inside your actionPerformed method for the reset action
squareButton.setSelected(true);
colorComboBox.setSelectedIndex(0);
if not be more clear in your post. -
I have a swing application with 2 JComboBox 's, 1 JPanel (for pictures), 1 JButton and a scroll pane. Basicall the JComboBoxes have an action listener that changes the pictures when I cahnge the names. However, I would like the Jbutton when pressed to display the name chosen (from the JComboBox) and display it in the textArea. See code below.

We are using Windows XP , Nvidia graphics card, with Multiview. I hope the problem is not specific to the platform.
It is reproducible with 1.4.2 and absent in 1.4.1

Problem with Combo Box in a Dialog Box
I have a dialog box that includes a combo box.
For some reason the combo box shows up under the first text box. In other words, the combo box is not separate from the first field. It has the following:
ComboBox with Sequence showing, then Enter Identifyer
Textbox URL
Textbox Enter Resource 1
Textbox Enter Resource 2
Textbox Enter Resource 3
Textbox Enter Resource 4
Textbox Enter Resource 5
It's putting the combo box in the first text field...it should be
ComboBox with Sequence showing
URL Textbox
Enter Identifyer Textbox
Enter Resource 1 Textbox
Enter Resource 2 Textbox...
Here is my code:

Problem with JTableHeader Render
Hello,
I am using JTableHeader renderer as below:
TableHeaderRender headerRender;
fixedModel.addColumn("");
TableColumnModel colModel = Table.getColumnModel();
for(int i=0; i<colModel.getColumnCount(); i++ )
colModel.getColumn(i).setHeaderRenderer(headerRender);
And the renderer is as below:
class FixedTableHeaderRender extends DefaultTableCellRenderer
JLabel label = null;
String[] selectList= {"Item1","item 2", Item 3", "Item 4"};
JComboBox ColStatBox= new JComboBox(selectList);
public FixedTableHeaderRender()
super();
label = new JLabel();
label.setOpaque(true);
label.setBorder(new LineBorder(Color.black));
label.setHorizontalAlignment(SwingConstants.CENTER);
label.setVerticalAlignment(SwingConstants.CENTER);
ColStatBox.setSelectedIndex(0);
ColStatBox.setEnabled(true);
ColStatBox.setAutoscrolls(true);
ColStatBox.addActionListener(new ActionHandler(){
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected,boolean hasFocus, int row,int column)
Component comp= null;
if(column==0)
comp=ColStatBox;
else
label.setText("100");
comp=label;
return comp;
Now in this for First column header the JComboBox is displayed and for rest of the column the label is displayed.
But in this, the JComboBox is not working i.e. I am not able the browse through the list. If I want to select any item (Item 4), its not allowing me to select.
How to make it enable and function normally?
Do reply.
Thanks and regards,
SheetalI've amended your code as shown. Some points:
1) Not sure what all the scroll bar stuff is for, I've removed it.
2) The method DefaultTableModel.addColumn is too crude. If you look at the JDK source it calls fireTableStructureChanged(). This has the effect of recreating the column model, which in turn resets all the widths. It will also clear out any renderers/editors you had set up within the TableColumn instances inside the TableColumnModel (if any). Those setup by column class would be OK (I think).
I didn't look into the remainder of your problem, hopefully you are OK now...

Swing JComboBox causes scrolling problems in applet
I have an applet with a JPanel that contains a JComboBox that lists font selections for a JTextPane in a JPanel below it. It contains about 12 items, of which only five are visible at a time. If I choose any of the first five and scroll the page on which the applet is running, there are no issues. However, if I scroll the page after scrolling down the list to the sixth item, regardless of whether or not I actually select it, it causes the graphics in the applet to corrupt. The JComboBox code is:
private JComboBox getFontFaceCB() {
String[] fontNames = new String[fontlist.length];
for (int i = 0; i < fontlist.length; i++){
fontNames[i] = fontlist.getFamily();
if (fontFaceCB == null) {
fontFaceCB = new JComboBox(fontNames);
fontFaceCB.setBackground(Color.white);
fontFaceCB.setPreferredSize(new Dimension(150, 30));
fontFaceCB.setMaximumRowCount(5);
fontFaceCB.setSelectedIndex(0);
fontFaceCB.addItemListener(new java.awt.event.ItemListener() {
public void itemStateChanged(java.awt.event.ItemEvent e) {
currentFont = fontlist[fontFaceCB.getSelectedIndex()];
StyleConstants.setFontFamily(textStyles, currentFont.getFamily());
jTextPane.setCharacterAttributes(textStyles, true);
viewWidget.repaint();
return fontFaceCB;
}This also happens if I set the default index to something that one must scroll down to reach (e.g. the sixth index) I was wondering if anyone else has come across this issue and has any idea as to how this may be resolved.
Also, if the window is minimized, resized, etc. the graphics also corrupt, but only after the aforementioned condition.
Edited by: BANZ111 on Dec 12, 2007 3:59 PMI have found the solution:
I had lightweight components intertwined with heavyweight ones, which, until now, I never regarded as being a possible source of problems. Apparently, when you scroll down a JComboBox, it changes from light to heavy weight? At any rate, I found this with a lot of other useful tips here:

Perhaps this can be of use to anyone else who gets a similar problem. -
Hi everybody,
i have a JTable and what I want to is that when the user type something in the TextField the table will show the names of the company that start with the letter that the user typed. But the problem is that each time the user type the event executes 2 times, this is the code:
private void txt_searchCompanyKeyReleased(java.awt.event.KeyEvent evt) {
TableModel model = jt_Company.getModel();
ArrayList<String[]> dataArray = new ArrayList<String[]>();
String[] data = new String[ jt_Company.getRowCount() ];
String s = txt_searchCompany.getText();
System.out.println("Cantidad de filas: " + jt_Company.getRowCount()+ "\nCantidad de col: " + jt_Company.getColumnCount());
for(int i = 0; i < jt_Company.getRowCount(); i++)
for(int j = 0; j < model.getColumnCount(); j++)
if(model.getValueAt(i, 1).toString().startsWith(s) == true)
data = model.getValueAt(i, j).toString();
dataArray.add(data);
System.out.println(" " + data[0] + "Tamano de ArrayList: " + data. length);
jt_Company.setModel(new Business.CompanyTable(dataArray));
}//End of the method
the method compares very well the string and the name of the companies in each row, but as mention before the method do it 2 times that means that the string array will the double of rows.
How can I do to make the event execute only one time
Thanks a lot.......Hi,
KeyListener is not probably a good idea for you. You should use DocumentListener. for Example:
jTextFieldIP.getDocument().addDocumentListener(new DocumentListener()
public void changeUpdate(DocumentEvent e){}
public void insertUpdate(DocumentEvent e)
try
jListCode.setSelectedIndex(Integer.parseInt(jTextFieldIP.getText()));
catch(NumberFormatException ne)
JOptionPane.showMessageDialog(null, "Only numbers in this field please.");
public void removeUpdate(DocumentEvent e)
insertUpdate(e);
} ); -
Problem, change the language with dynamic text
I am looking for a way to change simply the language of my flash animation
I work with flash cs4
of course I got Mylocale.as:
import mx.lang.Locale;
class MyLocale extends mx.lang.Locale {
static function start():Void {
var langCode:String = xmlLang;
currentXMLMapIndex = 0;
xmlDoc.load(xmlMap[langCode][0]);
static function setXMLLang(langCode:String):Void {
xmlLang = langCode;
and different xml files in the same folder than my swf file
in string , I ticked : "replace strings automatically during the execution"
with a default language (I am wondering if the problem is not from there)
if I tick: "replace strings manually using the scene language " or "replace strings via actionscript"
my code does not work.
then I kept: "replace strings automatically during the execution"
in my flash animation I have several scenes (pages)
p1, p2, p3, p4
in p1
I created a language bar
then 2 layers inside
Layer--action:
langListener = new Object();
langListener.change = function(eventObj) {
var target = eventObj.target;
var newLang = target.selectedItem.data;
MyLocale.setXMLLang(newLang);
MyLocale.start();
lang_cb.addEventListener("change", langListener);
// Force Japanese
lang_cb.selectedIndex = 1;
lang_cb.dispatchEvent({type:"change"});
Layer--language ex Fr:
// Forces combobox to have the correct value
on (release) {
var component = _parent.lang_cb;
for (var i=0; i< component.length; i++) {
var item = component.getItemAt(i);
if (item.data == "fr") {
component.setSelectedIndex(i);
component.dispatchEvent({type:"change"});
break;
ex Ja :
// Forces combobox to have the correct value
on (release) {
var component = _parent.lang_cb;
for (var i=0; i< component.length; i++) {
var item = component.getItemAt(i);
if (item.data == "ja") {
component.setSelectedIndex(i);
component.dispatchEvent({type:"change"});
break;
When I change the language in p1 , the language is also modified in p2, p3 and p4
however , after a navigation in p2, p3 and p4 , once I come back in p1 , the default language is back automatically although I did not touch the language bar!!
I don't know how to solve the problem
to my mind , the script reset itself each time I come back on p1
is there a way to keep the saved settings even when I am back on p1 until I modify manually again the language bar
