Synchronize JList with JScrollPane
hi all,
I want to automatically move the scroll in the JScrollPane when I change the selected position in the JList with setSelectedIndex, right now the list is correctly selected, but the scroll remains on the top, how could I move it to position the list to see the selected item?
thanks!
mykro
JComponent has a scrollRectToVisible method you could use along with JList's getCellBounds method. Maybe register a ListSelectionListener with the list, then in valueChanged get the newly selected cell's bounds from getCellBounds and call scrollRectToVisible on the JList with the cell bounds.

Populating JList with a single database column
Hi all,
I have the following code and i'm trying to popluate the JList with a particular colum from my MySQL Database..
how do i go about doing it??

Resizing a JList with variable row heights, not updating the "picture"
Firstly I would like to apologize for posting this Swing question here, but I was unable to find the Swing category, if someone could direct me to that I would be most grateful.
Ok, so in abstract what I am trying to do is have a JList with resizable rows to act as a row header for a JTable (exactly like the row headers in OO Calc or MS Excel).
What I have is a RowHeaderRenderer:
public class RowHeaderRenderer extends JLabel implements ListCellRendererand it has a private member:
private Vector<Integer> _rowHeights = new Vector<Integer>();which contains a list of all the variable row heights.
Then there is my getListCellRendererComponent method:
public Component getListCellRendererComponent( JList list,
Object value,
int index,
boolean isSelected,
boolean cellHasFocus)
// Make sure the value is not null
if(value == null)
this.setText("");
else
this.setText(value.toString());
// This is where height of the row is actually changed
// This method is fed values from the _rowHeights vector
this.setPreferredSize(new Dimension(this.getPreferredSize().width, _rowHeights.elementAt(index)));
return this;
}And then I have a row header:
public class RowHeader extends JList implements TableModelListener, MouseListener, MouseMotionListenerand you may be interested in its constructor:
public RowHeader(JTable table)
_table = table;
_rowHeaderRenderer = new RowHeaderRenderer(_table);
this.setFixedCellWidth (50);
this.setCellRenderer (_rowHeaderRenderer);
// TODO: grab this value from the parent view table
JScrollPane panel = new JScrollPane();
this.setBackground(panel.getBackground());
this.addMouseMotionListener (this);
this.addMouseListener (this);
this.setModel (new DefaultListModel());
table.getModel().addTableModelListener (this);
this.tableChanged (new TableModelEvent(_table.getModel()));
}and as you can see from my mouse dragged event:
public void mouseDragged(MouseEvent e)
if(_resizing == true)
int resizingRowHeight = _rowHeaderRenderer.getRowHeight(_resizingRow);
_rowHeaderRenderer.setRowHeight(_resizingRow, resizingRowHeight + (e.getPoint().y - _cursorPreviousY));
_cursorPreviousY = e.getPoint().y;
}all I am doing is passing the rowHeaderRenderer the values the currently resizing row should be, which works fine. The values are being changed and are accurate.
The issue I am having is that while this dragging is going on the row does not appear to be resizing. In other words the "picture" of the row remains unchanged even though I change the values in the renderer. I tried calling:
this.validate();and
this.repaint();at the end of that mousedDragged method, but to no avail, neither of them worked.
Again, I verified that I am passing the correct data in the RowHeaderRenderer.
So, anyone have any ideas how I should get the image of the RowHeader (JList) to update after calling my MouseDragged event?
Thank you for your time,
BrandonI was able to fix this some time ago. Here is the solution:
public void mouseDragged(MouseEvent e)
if(_resizing == true)
int newHeight = _previousHeight + (e.getPoint().y - _cursorPreviousY);
if(newHeight < _minRowHeight)
newHeight = _minRowHeight;
_rowHeaderRenderer.setRowHeight(_resizingRow, newHeight);
_table.setRowHeight(_resizingRow, newHeight);
this.updateUI();

hello all
i am writing a look and feel .
and when i have a JList with LineBorder with thinness = 2 and a item is selected ,
i cant see the complete text of the selected item
my question is there a simple way to make this work
without changing the list preferred size inside my application ?
thank you
here is an example
(please select the third item 'ccccccccccccccc')

Hello,
Can I have JList with an ImageIcon beside it?e.g
"imageicon" "sometext"
code snippet would be helpful.
ThanksHello,
little improvement-update, custom ListCellRenderer now checks whether object is a String only or a JLabel with an ImageImage. You can use it for both versions of JLists.

public class ImageTextList extends JFrame
private static String[]text = new String[10];

private static ImageIcon[] icons = new ImageIcon[labels.length];

for(int i=0; i<text.length; i++)
text[i] = "Images " + (i+1);
icons[i] = new ImageIcon( "../testproject/img/" + (i+1) + ".jpg");
labels[i] = new JLabel(text, icons[i], JLabel.CENTER);
public static void main(String[] args)
new ImageTextList();
public ImageTextList()
super("Image+Text in a JList");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//test with labels and text
JList list = new JList(labels);
list.setCellRenderer(new MyCellRenderer());
getContentPane().add(new JScrollPane(list));
pack();
setLocationRelativeTo(null);
setVisible(true);
class MyCellRenderer extends JLabel implements ListCellRenderer
private JLabel label = null;
// This is the only method defined by ListCellRenderer.
// We just reconfigure the JLabel each time we're called.
public Component getListCellRendererComponent(
JList list,
Object value,
// value to display
int index, // cell index
boolean isSelected, // is the cell selected
boolean cellHasFocus) // the list and the cell have the focus
String s = value.toString();
ImageIcon icon = null;
//checks whether the source is a label or another object(String only)
if(value instanceof JLabel)
{System.out.println("label");
label = (JLabel)value;
icon = (ImageIcon)label.getIcon();

JTable/jlist with word wrapping cells?
Hello all,
I got a simple looking problem but i can't seem to find any working solution for it:
A jtable or jlist with cells that wordwrap text (cells differ in height).
I found many examples on groups.google and this forum but they all seem to suffer a 100% processor load when 2 or more cells differ in height.
Can anyone point me to a working example?
Kind regards,
TwanThanks! That's a real live saver.
I had been looking for a solution for several days, strange google did not yet found the mentioned page, cause it contains usefull information.
I've just implemented the multiline table and it works without any problems and most important without 100% cpu usage.
The bucks are comming your way ;-) -

Controlling amount of rows in a jtextfield with jscrollpane
As part of a school assignment, I we have output going to a textfield that is scrolled with JScrollPane. Part of it is for when it comes to 400 lines, and another line is added, that the first line of the output is erased, and the new one is added. Are there simple methods of the API to do this, or should I perhaps store all the output in a string, use an int to count, and then substring it to the first \n ?
Thanks for the replies. Please dont give me direct answers, but help to find the answer, as I do not want to cheat.While I did not do a SSCCE, mine is not overly complicated on output. The first part of this was building a console client to connect to a server. This part is adding a GUI to it, with a bit of extra functionality. My writeMessage method of the console did a System.out.println. It now does a output.setText(output.getText() + "\n"+ date + msg); msg being the String parameter in the method. output is the JTextArea I have, and is passed to my Client object.
The output works fine, its just trying to cut the first line out when max is reached. Just doing 20 lines for now. I tried adding this, but it started cutting more and more off the start of the text.
if(output.getLineCount() > 20) {
try {
int firstRow = output.getLineEndOffset(0);
output.setText(output.getText().substring(0, firstRow));
catch(BadLocationException e) {
e.printStackTrace();

Mouse motion listener for JTable with JScrollpane
Hi All,
I have added mouse motion listener for JTable which is added in JScrollPane. But if i move the mouse, over the vertical/horizontal scroll bars, mouse motion listener doesn't works.
So it it required to add mousemotionlistener for JTable, JScrollPane, JScrollBar and etc.
Thanks in advance.
Regards,
TamizhanI am having one popup window which shows address information. This window contains JTable with JScrollPane and JButton components to show the details. While showing this information window, if the mouse cursor is over popupwindow, it should show the window otherwise it should hide the window after 30 seconds.
To achieve this, i have added mouse listener to JPanel, JTable, JButton and JScrollPane. so if the cursor is in any one of the component, it will not hide the window.
but for this i need to add listener to all the components in the JPanel. For JScrollPane i have to add horizontal, vertical and all the top corner buttons of Scroll bar.
Is this the only way to do this? -

JList in JScrollPane never shows horizontal scroll bar
I have a JList inside a JScrollPane. When I add a lot of cells to the list, the vertical scroll bar appears as expected. However, if I add a cell that would require lots of horizontal space in which to render, the horizontal scroll bar never appears.
Is there a way to make the JList take on the width of the widest rendered cell?
JoshHere's some code that will demonstrate the problem. Run the code, then resize the window so that the horizontal scroll bar should appear.

Go to the App Store and check out the Purchases List. If iPhoto is there then it will be v9.6.1
If it is there, then drag your existing iPhoto app (not the library, just the app) to the trash
Install the App from the App Store.
Sometimes iPhoto is not visible on the Purchases List. it may be hidden. See this article for details on how to unhide it.
http://support.apple.com/kb/HT4928
One question often asked: Will I lose my Photos if I reinstall?
iPhoto the application and the iPhoto Library are two different parts of the iPhoto programme. So, reinstalling the app should not affect the Library. BUT you should always have a back up before doing this kind of work. Always. -
Traversing JList with arrow keys
I've got a small problem when i try to traverse a JList with the arrow keys. When I'm at the first index of the list and press the UP arrow, I want to select the last index of the list.
switch (keyCode){
case VK_UP:
if(list.isSelectedIndex(list.getFirstVisibleIndex()))
list.setSelectedIndex(list.getLastVisibleIndex());
break;
}When I use this code, the program selects the second last index (not the last). How can I fix this problem?
Any suggestions will be appreciated.I found this thread useful but ultimately solved this another way using key binds. Maybe someone will find this useful.
public MyDialogConstructor() {
bindKeys();
private void bindKeys() {
InputMap inputMap = getJList().getInputMap(JComponent.WHEN_FOCUSED);

Synchronize form with self-referencing VO in tree table. POJO Based Model
Hello. I need your help
ADF Code Corner sample #32 show how to build a tree table from a self referencing VO:
[http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html#CodeCornerSamples]
ADF Code Corner document Oracle JDeveloper OTN Harvest 09/2011 by Frank Nimphius show how to build an edit form for the table data and how to synchronize it with the selected row in the tree table:
[http://www.oracle.com/technetwork/developer-tools/adf/learnmore/sept2011-otn-harvest-508189.pdf]
This examples are helpful, but i have a problem, i have not a model based on a database, my application datamodel is based in POJO objects, there are no appModules or ViewObjects so I do not know how to reference the tree table target attribute with the edit form iterator.
Can anyone help me?
Maybe (i dont know how) i need make a VO and a AppModule that wraps the POJO model ?
thank you very muchHi,
this should work the same. You create a tree from a POJO Data Control based on your POJO Model. Expose another collection pointing to the same data set and drag it as the form. Use the setting on the tree configuration dialog to set the current row in the tree as the current in the form iterator.
