Tableview custom cell problem

Hi everyone.
I created a iOS tabbed application using xcode 4.2 and storyboard. I added one tableviewcontroller with custom cell on it, when clicking the row, I want to open one tableviewcontroller, i used the following code below
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    categoryClass *cc = [datas objectAtIndex:indexPath.row];
    [tableView deselectRowAtIndexPath:indexPath animated:NO];
    iSubProducts *subProducts = [[iSubProducts alloc] init];
    subProducts.title = cc.categoryName;
    subProducts.catID = cc.categoryID;
    [[self navigationController] pushViewController:subProducts animated:YES];
    [subProducts release];
but when I click the row it gives me the following error:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath
on my iSubProducts tableviewcontroller, i have the following:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    static NSString *CellIdentifier = @"myCell2";
    iSubProductsCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    productSubClass *cc = [datas2 objectAtIndex:indexPath.row];
    NSLog(@"Product Name: %@", cc.productName);
    cell.txtProductName.text = cc.productName;
    cell.txtProductDesc.text = cc.productDesc;
    return cell;
I assume this is where the error occurs, the cell is returning a nil value. When I try to attach the iSubProducts tableviewcontroller using or from a button, it all works fine, but if its coming from row clicked, this error shows up.
Im quite new with iOS development, and maybe there is a error opening tableviewcontroller from a tableviewcontroller with a custom cell on it. I've been bangin my head for 2 days now and googled a lot, unfortunately I didn't find any solution. I'm pretty sure there's no error on the iSubProducts tableviewcontroller since its working if i tried pushing it from a button. Please I need advice on this one, Im so stucked right now with this issue. Thank you everyone.

Hi,
you need to create a tableViewCell in case the dequeueReusableCell-call doesn't return one.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    static NSString *CellIdentifier = @"myCell2";
    iSubProductsCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
        cell = (iSubProductCell *)[[UITableViewCell alloc] init....
    productSubClass *cc = [datas2 objectAtIndex:indexPath.row];
    NSLog(@"Product Name: %@", cc.productName);
    cell.txtProductName.text = cc.productName;
    cell.txtProductDesc.text = cc.productDesc;
    return cell;

How to handle too many custom UITableViewCells in UITableView?

In my iphone app, I need to display many custom rows (maybe thousands or even more) in the UITableView. I add one custom UIView onto each UITableViewCell in "- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath" function, so there will be allocate much memory for the all my custom UIViews. When I add 500 rows into the UITableView, the memory ran out, then the app crashed. I think maybe there is something wrong with my code or design, I don't know how to handle this (thousands custom rows in UITableView). Please help me.... Thanks very much..
Below is the my code:(if I have thousands of rows, the following code will allocate thousands of CustomViews), is there any way that not allocate so many CustomViews?
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
**cell = [[[UITableViewCell alloc] initWithFrame:CGRectMake(0, 0, 110, 25) reuseIdentifier:CellIdentifier] autorelease] ;
// Set up the cell...
CustomView *cellView = [[CustomView alloc]initWithFrame:CGRectMake(1, 1, 108, 24)];
[cell addSubview: cellView];
[cellView release];
return cell;
}

Hi,
well you should add the customView if you need to create a new cell only. Any reused cell will contain this customview allready since you've added it when the cell was created.
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithFrame:CGRectMake(0, 0, 110, 25) reuseIdentifier:CellIdentifier] autorelease];
// Add customView to new cell's only
CustomView *cellView = [CustomView alloc] initWithFrame:CGRectMake(1, 1, 108, 24)];
[cell addSubview: cellView];
[cellView release];
// Set up the cell...
return cell;

Problem with UITableViewCell, can´t add the same custom cell

Hi,
I have a table view which I populate the cells with a UITableView class that i wrote. This custom class has two labels and a image view. In the method cellForRowAtIndexPath, i use the following code:
[cell addSubview:myTableViewCellClass];
the first cell is ok, the cell displays my custom cell. But the second cell can´t display the same custom cell object. Is there something I can do to avoid this problem?
I have another problem. When i scroll my table view very fast, the program crashes with the following message:

This is not the correct method for using custom table cells with a table. You need to create a custom cell class that extends UITableViewCell. This class should handle the layout and display for the content of a single cell.
In your table view delegate's 'cellForRowAtIndexPath' method, you create or obtain an instance of your custom cell, configure the cell by setting the title or other properties appropriate for you custom cell, then return the cell. That's it.
It appears, from your code, that you are trying to add the table view cell class to the cell. Maybe you mistyped. But don't call 'addSubview' on anything within the table view delegate.
Have a look at the UICatalog example app. It has several custom table cells and shows both how to implement a custom cell, but also how to use it in a table.
Enjoy.

How to paint a Custom Cell while you are editing on adjacent Cell in JTabl

Hi All,
I have two Columns in my Custom Table . Both Two Columns are Custom Cell Editors/Renderers.
I have made UI such that Column1 is Label , Column 2 is TextBox / Combo/ UI Input any
My Custom Table View when i edit some value against Max Conn. it should display Blue
=================================
Column A | Column B
==================================
Timeout | some_unchanged_value
*{color:#0000ff}Session{color}* | some_unchanged_value
Log File | some_unchanged_value
===================================
My issue is when i start typing in my Custom Editor suppose i Type /invoke Edtir of Index 2, Column 2 font should become Blue.
It becomes blue only when i debug this issue it perfectly works, without Debugger it doesnt changes the Font
MyDefaultRenderer is my Custom renderer - I have set Foregroud Color as BLUE
NOTE:_
In run method if table.repaint() instead of single renderer:
It turns Blue when i make call on table.repaint() methosd but i feel that repainting full table on every key Stroke should not be very good programming. Whats is more appropriate way?
I want to repaint only that particular cell against which i change the Value
    private class MyDefaultEditor extends AbstractCellEditor implements TableCellEditor {
        private JTextField txtField = null;
        private int rowIndex;
        public MyDefaultEditor() {
            txtField = new JTextField();
            txtField.addKeyListener(new KeyAdapter() {
                @Override
                public void keyTyped(KeyEvent e) {
                    super.keyTyped(e);
                    System.out.println("########### Hello This is MyDefaultEditor");
              SwingUtilities.invokeLater(new Runnable() {
                        public void run() {
                              // Call Renderer adjacentt to input to turn Blue (Is this Valid Code ??)
                            MyDefaultRenderer defRen = (MyDefaultRenderer) thisTable.getCellRenderer(activeRowIndex, 0);
                            defRen.paintMe();
          // table.repaint() works for me but i dont want to call it on evey ket type, that will be Heave rite???
        public Component getTableCellEditorComponent(JTable table,
                Object value, boolean isSelected, int row, int column) {
            rowIndex = row;
            String valStr = "";
            if (value != null && value instanceof String) {
                valStr = value.toString();
            txtField.repaint();
            return txtField;
        public Object getCellEditorValue() {

Well, I think you need to add a custom renderer to the first column. The renderer would check if the table.isEditing(). If it is and the editing is done on the same row, then you set the font color blue, otherwise you use the default font color.
Then the next question is how do you repaint the cell. Well you can use the table.repaint(Rectangle) method. You can get the Rectangle to repaint by using the table.getCellRect(...) method.
Finally, you need to know when to repaint the cell. Well a PropertyChangeEvent is fired when a cell starts and stops editing. So you only need to handle these events. Don't use a KeyListener. The PropertyChangeListener you add to the table might be something like:
public void propertyChange(PropertyChangeEvent e)
     if ("tableCellEditor".equals(e.getPropertyName()))
          if (table.isEditing())
               processEditingStarted();
          else
               processEditingStopped();
}So when editing is started you need to determine the "adjacent" cell you want to repaint to the blue font is used. You would save the cell Rectangle so you can restore the font when editing is stopped.

Event Handling in JTable Custom Cell Renderer

I have a JLabel as a custom cell Renderer for a column. I want to handle mouse click event for the JLabel rendered in the cell.
I tried adding the listener for the label in the custom cell renderer but it is not working. Any ideas how to handle this problem??
Thanks

If you want to handle the selection of a tree node
1) write a class like:
public class TreePaneListener implements TreeSelectionListener {
// TREE SELECTION LISTENER
public void valueChanged(TreeSelectionEvent e) {
JTree tree = (JTree)e.getSource();
DefaultMutableTreeNode node = null;
int count = 0;
boolean doSomething = false;
if(tree.getSelectionCount() > 1) {
     TreePath[] selection = tree.getSelectionPaths();
     int[] temp = new int[selection.length];
     for(int i =0; i < selection.length; i++) {
// Check each node for selection
     node = (DefaultMutableTreeNode)selection.getLastPathComponent();
     if(node.getLevel()==2) {
// Change this code to take the action desired
     doSomething = true;
2) After creating the tree register the listener
TreePaneListener handler = new TreePaneListener();
tree.addTreeSelectionListener(handler);

Using JScrollpane via Custom Cell Renderer.Please Help

Chaps,
I have a question regarding scrolling of a JList.
I have written a class (FTRDList) that has an Custom Cell Renderer.
I want the list to be scrollable.
This class is being called by many other classes.
Now,as the FTRDList class is being called by many classes,i need
to have all these classes to have the flwg statement
add(new JScrollPane(FTRDList)),BorderLayout.CENTER);
This can be a lot of work to chaneg all classes
Rather,is it possible to have the JScrollPane built in the
FTRDList class once and for all and let all classes call
it by
add(FTRDList,BorderLayout.CENTER);
Please can anyone tell me how to make the FTRDList class Scrollable?
Or is this not possible at all?
Attached is the class:
public class FTRDList extends JList {
    /* Inner class for Custom Cell Renderer */
    class MyCellRenderer extends JLabel implements ListCellRenderer {
    public Component getListCellRendererComponent(JList list,

Performance decrease with custom cell renderer

Hi,
Finally, I have my cell renderer working fine (it was simpler than I thought). Anyway, I'm suspecting something is not working quite well yet. When I try to reorder my colums (by dragging them) they move like slow motion. If I don't register my custom cell renderer, I can move my columns fine. Next is the code of my custom renderer.
class PriorityRenderer extends DefaultTableCellRenderer {
public Component getTableCellRendererComponent(
JTable table, Object value,     boolean isSelected,
boolean hasFocus, int row, int column) {
    if(value instanceof coloredValue) {
    coloredValue cv = (coloredValue)value;
    if(isSelected) this.setBackground(table.getSelectionBackground());
    else this.setBackground(cv.getbkColor());
    this.setForeground(cv.gettxColor());
    this.setText(value.toString());
    this.setOpaque(true);
    return this;
}All the cells of my JTable are "coloredValue"s. This is a little class with a String, two colors and some getter methods.
Can anyone giveme a hint ?
Thanks!!

OK! Now the performance problem is gone!! (I don't know why, I didn't touch a thing)
Thanks anyway

Help with JTreeTable custom cell renderer!

Hi.
I've followed diligently the complete TreeTable2 example found on the Sun site. http://java.sun.com/products/jfc/tsc/articles/treetable2/
What I'm trying to do is to add alternate-row shading on the Column(0) of the JTreeTable where the Column class is "TreeTableModel".
so, from the example, I've added the following setCellRenderer declaration to TreeTableExample2.java:
     protected JTreeTable createTreeTable() {
          JTreeTable       treeTable = new JTreeTable(model);
          treeTable.getColumnModel().getColumn(1).setCellRenderer
          (new IndicatorRenderer());
          treeTable.getColumnModel().getColumn(0).setCellRenderer
          (new MyTableCellRenderer());Then, I subclass DefaultTableCellRenderer as shown below, in a new class called "MyTableCellRenderer"
import java.awt.Color;
import java.awt.Component;
import javax.swing.JTable;
import javax.swing.table.DefaultTableCellRenderer;
import javax.swing.table.TableCellRenderer;
public class MyTableCellRenderer extends DefaultTableCellRenderer implements TableCellRenderer
     private static final long serialVersionUID = 1L;
     public MyTableCellRenderer() {
     public Component getTableCellRendererComponent(JTable jtable, Object obj, boolean isSelected, boolean hasFocus, int i, int j)
          if (i % 2 == 0 && !isSelected) {
               this.setBackground(new Color(214,226,255));
               this.setForeground(Color.BLACK);
          } else if (isSelected)
               this.setBackground(new Color(204, 204, 255));
          else {
               this.setBackground(Color.white);
          //if (obj != null)
          this.setValue(obj.toString());
          System.out.println("obj: " + obj.toString());
          System.out.println("obj type: " + obj.getClass().getName());
          return ((Component) (this));
}I've been pulling out whatever few hairs I have left in my sparse scalp to get this working, but it's looking grim thus far.
Here are links to screenshots of my progress, or lack thereof:

My Not-working Tree Table II w/ Custom Cell Renderer

thanks again - !!

phew! finally got this sucker working. I had to retrieve the default rendererer of my TreeTable's TreeTableModel class column, which is the JTree and then, in its component-form, start mucking about with its stylings. The real black-hole of progress was caused by my brain imploding from not being able to understand that a "Component" was what represented the "thing" whose behaviour I wanted to alter, be it a Jtree node or Jtable cell.
          treeTable.getColumnModel().getColumn(0).setCellRenderer(new TableCellRenderer() {
               public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int col) {
                    Component comp = treeTable.getDefaultRenderer(TreeTableModel.class).getTableCellRendererComponent(table, value, isSelected, hasFocus, row, col);
                    if (row % 2 == 0 && !isSelected) {
                         comp.setBackground(new Color(214,226,255));
                         comp.setForeground(Color.BLACK);
                    } else
                         if (isSelected)
                              comp.setBackground(new Color(204, 204, 255));
                         else {
                              comp.setBackground(Color.white);

Inconsistent behavior with Custom Cell Renderer

I have two questions:
Questions # 1.
I have created a custom cell renderer for my JTable that changes color if the text property changes and the text contains the letter 'S'. Like
so:
class SchedRenderer extends DefaultTableCellRenderer{
public SchedRenderer(){
super();
final Color c = scSelfCont.panelbg;
this.setForeground(c);
this.addPropertyChangeListener("text",new PropertyChangeListener(){
public void propertyChange(PropertyChangeEvent e){
     boolean foundS=false;
     String text=e.getNewValue().toString();
     for(int i=0;i<text.length();i++)
     if(text.charAt(i)=='S'){
     foundS=true;
     break;
     if(foundS){
     SchedRenderer.this.setBackground(Color.red);
     SchedRenderer.this.setForeground(Color.red);
     else{
     SchedRenderer.this.setBackground(c);
     SchedRenderer.this.setForeground(c);
99% of the time it works just fine. But occasionally the cell will revert back to its original color, and then back to the correct color after clicking somewhere entirely different. I set some breakpoints in the property change handler and it gets called quite frquently even if no change has been made. At first I thought this was a JDK bug, but I am now convinced that there simply must be a better way to do this, any ideas?
Question # 2:
Is there a simple way to change the color of an entire row without selecting it? Currently I am using Custom Cell Renderers to change
colors of cells, but it seems like such an obtuse method. Is there a better way?
Thanks in advance.

JTree custom cell renderer question

When using a custom cell renderer is their anyway to tell the offset of the current node?
For example if you have a tree with the parent node "Parent" that has a few children nodes it will look something like this:
Parent
|----Child 1
|----Child 2
|----Child 3
So the parent would have an offset of zero. I want to know how to get the childrens offset? If this is possible?
What I am trying to accomplish:
I have a JTree as a scrollpane rowHeader. While the main body of the scrollpane is a JTable. I need the tree's nodes to fill the entire width so that it looks like part of the table. I figure the row header width - current node offset should be the width that I will need each node to be. Any help is welcome. Thanks.

the renderer tells you the row, the tree can get you a treepath for a row
TreePath getPathForRow(int row)
That can tell you the depth of the node.

TableSorter + custom cell renderer: how to get DISPLAYED value?

Hi!
I have a JTable with a custom cell renderer. This renderer translates numerical codes, which are stored in the table model, into textual names. E.g. the table model stores country codes, the renderer displays the name of the country.
Now, having a reference on the JTable, how can I get the DISPLAYED value, i.e. the country name? Is there some method like ....getRenderer().getText()?
Thanx,
Thilo

Well, a renderer can be anything. It may be rendering an image not text so you can't assume a method like getText(). However, since you know the component being used to render the cell you should be able to do something like:
TableCellRenderer renderer = table.getCellRenderer(row, column);
Component component = table.prepareRenderer(renderer, row, column);
Now you can cast the component and use get text.
Another option would be to store a custom class on the table cell. This class would contain both the code and value. The toString() method would return the value. Whenever you want the code you would use the table.getValueAt(...) method and then use the classes getCode() method. Using this approach you would not need a custom renderer. This thread shows how you can use this approach using a JComboBox, but the concept is the same for JTable as well:

Drop mouse cursor disappears after setting custom cell renderer in table.

Hi,
I've a JList and a JTable, drag&drop works ok between them. Now, if I change TableCellRenderer to custom cell renderer, say a descendent of JComponent that implements TableCellRenderer, it doesn't display drag cursor when it's on top of a cell, and on 1 pixel grid lines it displays right again. can someone help me to fix this issue.
Regards, thanks in advance,
Ozgur

it doesn't display drag cursor when it's on top of a cell, and on 1 pixel grid linesThe following renderer works ok for me, although I must admit there is a slight "flicker" when you move over the grid line. Not sure why that happens.
     class MultiLabelRenderer implements TableCellRenderer
          private JPanel panel;
          private JLabel red;
          private JLabel blue;
          public MultiLabelRenderer()
               panel = new JPanel(new BorderLayout());
               red = new JLabel();
               red.setForeground(Color.RED);
               blue = new JLabel();
               blue.setForeground(Color.BLUE);
          public Component getTableCellRendererComponent(
               JTable table, Object value, boolean isSelected,
               boolean hasFocus, final int row, final int column)
               String text = value.toString();
               red.setText( text.substring(0,1) );
               blue.setText( text.substring(1) );
               panel.removeAll();
               int columnWidth = table.getColumnModel().getColumn(column).getWidth();
               int redWidth = red.getPreferredSize().width;
               if (redWidth > columnWidth)
                    panel.add(red);
               else
                    panel.add(red, BorderLayout.WEST);
                    panel.add(blue);
               if (isSelected)
                    panel.setBackground( table.getSelectionBackground() );
               else
                    panel.setBackground( table.getBackground() );
               return panel;
     }
