Swing/AWT/SWT :: Changing Color Of JList Item
Oct 23, 2014is there a good way to change the color of a JList item that isn't selected? I'm throwing my hand at building a client/server chat app and on the client side, I need to highlight the name of the person (which is in a JList) who has sent a message to the client GUI.
View Replies View RelatedSwing/AWT/SWT :: Alternative To Making Static JList?
Sep 16, 2014I am currently writing a chess application in Java swing. For the GUI part, I have one MainWindow class, and one ChessBoard class. The MainWindow has a main panel, in which is contained 1) a panel containing the chessboard from the chessboard class (a grid layout array of 64 JLabels), 2) a JLabel status bar, and 3) a JList to hold the moves of the game. I have a movePiece method in the chessboard class, which I would like to add the move and question to the moves list, which is contained in the main window class.
However, since JList is some special type, I can't make it static ( that gives me an error ). I also tried creating a method in the main window class to add a move to the list, which I would then access via the chessboard class. However, I can't make the method static, because it is referencing a non-static variable ( the JList ), and since the Main window class already has an object of the chessboard class, trying to create a main window object in the chessboard class creates a stack overflow error.
Swing/AWT/SWT :: How To Fill Text Fields With Selection From JList
May 2, 2015I have an addressBook GUI where I have a JList that populates with the contacts names, and once I double click a contacts name I'm wanting to fill the textfields with the contacts corresponding data.
ex) ContactType: Family (enum), Name: Zoidberg, Address: 111 Space Drive, City: New York City, etc...
I've got it to where I select open from the JMenu, it populates the JList, but once I select a contacts name, all the textfields are populated, but only with the contacts name
ex) Name: Zoidberg, Address: Zoidberg, City: Zoidberg, etc....
What am i doing wrong here, and how can i fix it to where it fills out the correct data?
Here's my code so far:
public class AddressBookGUI extends JFrame {
private final int WIDTH = 450;
private final int HEIGHT = 300;
private JLabel currentlySelected;
private JTextField contactTypeTextField;
[code]...
I'm certain the logic is messed up near the end where i set all text fields to the index, because no matter what field i want to fill it's at it's going to set it to whatever index I select, but I don't know how to fix it.
Swing/AWT/SWT :: Create A Sub Menu For Every List Item In A Jlist
Oct 8, 2014I would like to create a sub menu for every list item in a Jlist. I need the UI like avast interface. If we hover over an list item, its sub menu should be shown. I attempted to put an sub menu but didn't work. Is this possible in Swing?
View Replies View RelatedSwing/AWT/SWT :: MouseListener Doesn't Work If JList Has Custom CellRenderer
Nov 9, 2014I have a JList<Object> in my code (it actually takes JLabels) called imageList, and I've given it a custom CellRenderer using the following code:
cellRenderer = new DefaultListCellRenderer() {
private static final long serialVersionUID = 1L;
@Override
public Component getListCellRendererComponent(JList<?> list,
Object value, int index, boolean isSelected,
boolean cellHasFocus) {
[Code] .....
However, when I click anywhere on the JList, nothing gets printed to the console, which suggests that the mousePressed() method isn't being invoked. I think it's a problem with the CellRenderer, because I have similar code elsewhere that works, the only difference being I don't use a custom CellRenderer.
Swing/AWT/SWT :: Java GUI With Separate Class For JList - Adding Items To The List?
Sep 19, 2014I am trying to create a GUI interface in swing which consists of four classes: a GUI class, which creates a main JPanel, a label, and a JList, which it takes from the second class, a MovesList class that contains a JList and the stuff needed to interface with it. It also has a main class, which basically just creates an object of the GUI class for the main window, and an Other class from which I would like to be able to add an item to the JList. I created methods in the MovesList class to get each component (like getMoveslist, or getMovesListScrollPane), which I then used to create the JList in the GUI class. I also created an addMove method so that I can add an item to the JList from any class through a MovesList object. However, this addMove method only works when called from the GUI or MovesList classes -- it does nothing when I collect from the Other class.
Here is my code:
//Main class
public class TestProject {
public static void main(String[] args) {
GUI mainWindow = new GUI();
mainWindow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
[Code] ....
When I run this code, I get a window with a JLabel that says "Moves," and a JList that contains five elements -- test 1-test 5, but not a sixth "test from other class." ( using the add move method ) However, when I click on the window, the addMove method is also called, and successfully adds "test 6" to the list.
Swing/AWT/SWT :: JTable With Fixed Row
Nov 9, 2008My JTable has a row, row number 0, which I always want to be at the top.I tried the following two approaches, both without success:
1- Use a custom table cell renderer for the header, and create a header of two rows. the second row is my JTextField.
Problem: I cannot get the JTextField to function properly. (I've seen examples with a checkbox in the header, but that one just reacts to a click somewhere on the header, my textfield must be editable).
2- Use the first row of the table. This works quite nice. However, I must prevent row 0 to be re-ordered when sorting the table.
I was thinking to add a prefix (either something like "___" or "zzz" depending on current sorting mode), but I do not know which methods to adjust for this exaclty.
Another approach would be to have N textfields above the JTable in some layout (or two JTable's on top of each other).
However, Then I would need to react to the re-ordering and re-sizing of all columns as well, which does not seem easy to me.
Swing/AWT/SWT :: Can't Select The Very Last Row In A Jtable
Mar 26, 2015I have encountered a very tricky spot in a project that i am working on. I must have a JTable to programmatically select the very last row in an AbstractTableModel. I have tried every thing but nothing works so far.
The problem is is that the JTable only scrolls down to the second last table row in the model? What am i missing?
//Show the very last row in a tablemodel object using the method updateTableRows
//after an "insert action event" occurred
public void updateViewMode(String name,
java.util.List<NetworkSwitch> list,
boolean flag) {
CableTableModel model = cableTable.getCableModel();
[code]....
What happens is that the only row that gets selected is the second last row of the total rows iny AbstractTableModel object, "CableTableModel"
What am i missing?
Swing/AWT/SWT :: JTable Not Getting Updated
Nov 17, 2014I am preparing a small solution. Below is how the functionality works.
1. Login Screen
2. Successful Login will take to a MDI Form
3. Click the menu, a JInternalFrame will open in the JDestopPane.
4. JInternalFrame has a JTable.
5. JInternalFrame has a JButton available for adding new data.
6. When JButton is clicked, a new JInternalFrame is popped up with some JTextField and JButton to save the data.
7. After saving the data (after insert query), a JDialog is opened to upload Logo (update query for BLOB), There are two buttons in the JDialog, one is for uploading the image, another one is uploading it later.
8. The logo is displayed in the JDialog and if the JButton, for upload is pressed, update the database and reload the JTable in the JInternalFrame is called.
My challenge is in point 8. The function is called properly, but the table is not getting refreshed.
JButton in JDialog for uploading the Logo
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
JOptionPane.showMessageDialog(this, "Image Uploaded Successfully");
companyConfig cc = new companyConfig();
//cc.reloadTable();
cc.updateTable();
this.dispose();

Swing/AWT/SWT :: JTable Sum Of A Column
Feb 9, 2015I've been creating a jTable where I can add / edit /delete new entries. Now i have 2 Questions :
1) My column 0 is filled with the row-number. I created a variable and with each "add" it adds +1 to the variable. That works, but as soon as i delete 1 row there is a gap ( 1..2..4..5..).
My question: Is there another way then mine to handle this?
2) The table is/should be working as some kind of database. The user is able to add Information (height, width,...). Now I want to sum the entries of 1 column (length,...). But as they´re objects I didn´t find a way.
My question: How can I sum the entries of 1 column of a table?

Swing/AWT/SWT :: How To Get Data From JTextField Over To JTable
Jun 20, 2014I am trying to get the data entered in a JTextField into a JTable but not clear on how. The LeftPanel is where the button is located and the RightPanel is where the JTable is. I want the actionPerformed to update the row of the JTable but I can't figure out how. There is another class that controls the GUI but did not think it was necessary to include. Also, I am aware that I am getting an error at the addRow line, can't seem to alleviate it.
public class LeftPanel extends JPanel {
private static final long serialVersionUID = -2311952438693382407L;

Swing/AWT/SWT :: Getting A Row Of Names From The First Column Of JTable?
Feb 9, 2014I have a JTable with the model " Names " , " Quantity " and " Unit " .
I'm coding a program where you get the ingredients names.
So i need to get the whole row of one column and String it all up together,because i need to store it in mySql and i have already set it all as String.
how i can do this ?
My code are as follows :
JTable Code:
DefaultTableModel model = (DefaultTableModel)table.getModel();
if(!txtQty.getText().trim().equals("")){
model.addRow(new Object[]{ingCB.getSelectedItem().toString(),txtQty.getText(),unitCB.getSelectedItem().toString()});
}else{
JOptionPane.showMessageDialog(null,"*Quantity field left blank");
}
Getting the values and for storing :
for(int i = 1; i<= i ; i++){
ingredients = table.getName();
}
This is for loop is wrong and it does not work because i have a constructor to take in Ingredients but because it is inside the loop, it cannot take it in.
Swing/AWT/SWT :: Refreshing JTable From Database

Swing/AWT/SWT :: How To Make A Row Of JTable Not Editable
Feb 8, 2014When I click on a row in a JTable, I want to have a row appear above it. For now I'm just making that row be a duplicate of the row I clicked on, but eventually this will be some sort of previous history of that row, so as you are editing the row you actually clicked on you can look directly above it and see what the data used to look like.
I"m not having any problem creating the row, nor am I having an issue getting it positioned correctly. What I want to do with this added row is made it so you can't edit the entire row, and also really make this row stand out. I'd like to say make this row stand out or "POP" so to speak so there is no confusing what it is. I'd almost like to make it look like the row header or even better... Most of what I am seeing are ways to make particular cells uneditable, so I think my backup plan is that, but Is there a good way to do what I described?

Swing/AWT/SWT :: How To Get Double Value Into JTable Cell
May 29, 2014My latest issue was that I wanted to only get a double value into a JTable Cell.
So first I Overrode the getCellEditor(int row,int col) method of my JTable, so if I was in a cell i knew I needed a double value I returned my Editor.
My editor filters out anything but numbers. I also check to make sure we get one and only one decimal point.
Other solutions Ive seen use keyboard Listeners, but to me that doesn't work. What if the user cuts and pastes data? My solution handles that as well.
It doesn't handle if they try to cut and paste something like 1234abcd.bob.123.23 , this would result in 1234..123.23 pasted in. I'll handle faulty values on the getValue method of my AbstractTable, but as long as the user is using mostly valid data this works well.
public TableCellEditor getCellEditor(int row, int col) {
if (row==TheRowWant && col==TheColumnI want) {
return (new DefaultCellEditor(createDoubleTextField()));
}
}
private JTextField createDoubleTextField() {
final JTextField field = new JTextField();

Swing/AWT/SWT :: Finding Strings In A JTable
Jan 31, 2015I am having a problem finding string objects in a jTable. I use setValueAt() to write string variables into a jTable.
I can then use getValueAt() to search to find any of those strings. All works fine until I edit an entry in the table. Then I can never find that string again.
In fact, if I just click in the cell type a character, then delete that character, something changes. The contents of the cell look the same but the search for it doesn't find it.
For example if I have a string "xyz" that was written in a cell. If I set the search value, "a=xyz", and "b=getValueAt(some cell)".
Then at the compare:
if(a==b) I can hover over a and b and I see that;
a = (java.lang.String) xyz
and
b = (java.lang.String) xyz
[note I am using NetBeans to do this]
after the compare, the true path is taken .
If I then click in the cell then click out and try the same compare, everything is exactly the same including what gets reported when I hover. But the false path is taken at the "if".

Apr 17, 2014I'm having serious issues right now with a JTable inside a JScrollPane.i have some methods that returns different indexes (rows) that i select programatically in a JTable and the problem is that sometimes it goes beyond of what i can see, like, the row gets selected but the scrollbar won't follow up.
i've searched up in google and saw several different methods but those were extremely complex and for stuff i don't need.the simplest solution i found is this:
tInfo.setRowSelectionInterval(searchIndexes.get(currentIndex), searchIndexes.get(currentIndex));
tInfo.scrollRectToVisible(tInfo.getCellRect(currentIndex, 1, true));
but it just doesn't do anything.My table (tInfo) has only two columns so no horizontal bars, just vertical. What can i do to align the scrollbar with the currently selected row in my table? :C
Found a solution using scrollPane.getVerticalScrollBar().setValue();in another thread, i didn't even notice there were like 3 more threads about the same, just different kind of code used in each.

Swing/AWT/SWT :: Refreshing Data In A JTable?
Apr 24, 2014I have been trying to learn a bit about JTables for a project I want to undertake. I have created a new JFrame in netbeans and added a button. Onclicking the button I want add some data to a JTable model and then output the JTable with the data. When I click the button again I want the same process to happen again and overwrite the previous table being displayed.
I have written the following code below:
import java.awt.Color;
import java.awt.Dimension;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
[code].....
The problem I have is that when I click the button for a second time the table stays on the screen exactly as it did following the first click. I can see that the data in the model is changing so I am not sure why a new JTable is not drawn.
