Swing/AWT/SWT :: JTable Not Able To Render Rows In Different Colors

Aug 24, 2014

I have a jtable , a customtablemodel and a customcellrenderer with the NetBeans IDE. I want to have different colors for different rows. But anytime I run the application , the rows are not painted as expected. The code snippets are provided below.

This code is from the jtable :

duesTable = new javax.swing.JTable();
duesTable.setModel(duestableModel);
TableColumn tcol = duesTable.getColumnModel().getColumn(2);
tcol.setCellRenderer(new CustomTableCellRenderer2());
duesTable.setAutoResizeMode(javax.swing.JTable.AUTO_RESIZE_OFF);

this code is from the TableCellRenderer

public class CustomTableCellRenderer2 extends DefaultTableCellRenderer{
@Override
public Component getTableCellRendererComponent (JTable table,
Object obj, boolean isSelected, boolean hasFocus, int row, int column) {
Component cell = super.getTableCellRendererComponent(
table, obj, isSelected, hasFocus, row, column);

[Code]...

This is from the Table Model.

public class DuesTableModel extends AbstractTableModel implements TableModelListener {
private List<List<Object>> dataList = new ArrayList<>();
private String[] header = { "ID"," PAYMENT YEAR" , "AMOUNT"}; // Payment year is a date
datatype
private int minRowCount = 5;

[Code]....

Swing/AWT/SWT :: Matching Strings To Selected Rows In JTable

Nov 10, 2014

I have a JTable which shows pdf files. In Addition I can check if they have errors, if it so I can generate a "report" by clicking the pdf. But the report gives me errors from all of the pdfs in the table. How can I match the error messages to the pdf which I select?

Here is one of the checking methods:

public static void testAllPagesHaveSameRotation(PDFDocument pdf) throws PDFDocumentException {
if (SettingsGui.testAllPagesHaveSameRotation.isSelected()) {
if (pdf.getPages() == 0) {
rotationError = "";
} else {
rotationError = "";

Swing/AWT/SWT :: Button Colors Different In XP And Win 8

Jan 26, 2015

I have a program I wrote long ago. I change colors of buttons at times. Here is the code:

for(int Player=0; Player < 8; Player++){
//make them all background
dealerLabels[Player].setBackground(new java.awt.Color(212,208,200));
}
//Now make the new dealer green
dealerLabels[dl].setBackground(new java.awt.Color(51, 255, 0));

The color of the buttons has always changed under XP but when I run the program on Windows 8 only the edges of the buttons change.

Swing/AWT/SWT :: Rows In JTextArea - Entering More Lines Than Limit

Jan 9, 2014

Here's a snippet of code from a program I'm making:

private void init() {
...
testInfo = new JTextArea("Progress log:
");
testInfo.setEditable(false);
testInfo.setLineWrap(true);
testInfo.setPreferredSize(new Dimension(testInfo.getPreferredSize().width, 200));
scrollPane = new JScrollPane(testInfo);
scrollPane.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
scrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
...
add(scrollPane);
}

The problem is, the JTextArea that's created has a "limited" number of rows - it seems you can still enter more lines than the "limit", but they don't show. I thought it was a problem with the JScrollPane but I'm not so sure...

JSF :: How To Render More Than One JSP Pages Into 1 Single View

May 15, 2014

I have an application where the WebContent folder has a number of .jsp pages like navigation.jsp, primarytabs.jsp etc.

The navigation.jsp contains a vertical menu and the primarytabs.jsp contains a tab on top, and some other jsps contain individual components.

When I run the application of the application server, it opens up a welcome page, and all these navigation items, and tabs and others merge into a single view and show us a well formed combination of all these components.

I did some studying and read about "composite views". But I wasn't sure if I can call this composite view or not.

How JSF combines all these jsps into one view and where to find that "binding" within the code so I can make the relevant changes?

Swing/AWT/SWT :: JTable With Fixed Row

Nov 9, 2008

My 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, 2015

I 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, 2014

I 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, 2015

I'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, 2014

I 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;
private RightPanel rPanel;
public LeftPanel(){
Dimension size = getPreferredSize();
size.width = 250;
setPreferredSize(size);

Swing/AWT/SWT :: Getting A Row Of Names From The First Column Of JTable?

Feb 9, 2014

I 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 :: How To Make A Row Of JTable Not Editable

Feb 8, 2014

When 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, 2014

My 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, 2015

I 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".
