Swing/AWT/SWT :: Code Prevent Cursor From Moving When Inside A Cell Of JTable

Jun 24, 2014

Tried creating a simple sample but all works as expected.

The following code prevents the cursor from moving when inside a cell of a JTable.

public void keyPressed(KeyEvent e) {
if ( (e.getKeyCode() == KeyEvent.VK_KP_LEFT) || (e.getKeyCode() == KeyEvent.VK_KP_RIGHT)
|| (e.getKeyCode() == KeyEvent.VK_RIGHT) || (e.getKeyCode() == KeyEvent.VK_LEFT) )
{
//Do nothing
e.consume();
}
}
});

When editing a cell, the existing code would use the right/left cursor keys to move from cell to cell as opposed to from character to character when editing a cell. I planned to override the functionality by tossing in the above code as a test to see if it stops the functionality before I override it.

After placing in the above code, the above functionality no longer occurs, but now the cursor moves within the cell as I wanted which is to move from character to character instead of cell to cell. Its great it works, but it really shouldn't. Essentially the default behavior has been restored when it should have really disabled the left/right keys.

I assume there is some underlying class someplace that is doing something to affect the behavior. Since a sample can't be provided I am wondering in what scenarios would the e.consume() restore default functionality?

Swing/AWT/SWT :: Update JTable Cell Values Inside A Loop

Jan 5, 2015

I have a program where i want to indicate the user when i have completed a task which i am running inside a for loop. Below is my code.

for(Map.Entry<Double,SimplestCopyInstance> entry : myList.entrySet()){
double key = entry.getKey();
SimplestCopyInstance scp = entry.getValue();
Copy cp = new Copy();
cp.putLocations(scp.getSrc(), scp.getDes());
scp.setStatus(cp.baseCopy()+"");

[Code] ....

I have used netbeans to build my app. So there creating jTable is out of my control as that part was inside auto-generated code. I have just used the jTable.setValue().

My problem is, above method is inside a button click event. Updated values not displaying until the loops ends.

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 :: Peculiar JTable - Cell Value Vanishes

Aug 20, 2014

I am facing some peculiar issue with JTable.

Change value of a cell, without clicking on anywhere else, directly click on column (or) try to expand column size, value you entered in that cell vanishes. But if you click on any other cell instead of expanding column size, value will remain in cell. Not really sure how to fix this issue.

Swing/AWT/SWT :: Custom JTable Renderer And Cell Editor

Jul 23, 2014

What I'm trying to do is make an inventory type program that includes a jtable. In the Jtable in the last column there will be 2 buttons and a textfield to register the value of additions or subtractions to the overal stock amount. (See screenshot in attachment).

As of now I am able to increment or decrement the numbers when the buttons are clicked on however the problem is that if I add 2 to the first row, and then go to add 2 to the next row or any other row for that matter, the value of the previous row is added to the next row, and the previous row reverts back to a value of 0. So basically its like there is only one editor that keeps track of one value no matter what row you are editing.

I need getting it so that I can add different values to each different row depending on the stock being used or received. The following is my code:

Main class

JScrollPane scrollPane = new JScrollPane();
scrollPane.setBounds(10, 155, 643, 233);
IMG.add(scrollPane);
center = new centerJustify();
ts = new tableCellRenderer();
tm = new DefaultTableModel(){

Swing/AWT/SWT :: Making A Custom Cell Renderer Work In A JTable?

Jan 24, 2014

Now my issue is I have a JTable. The first column will contain Date objects all the way to the bottom. I want the JTable to display only the month and year. I created a custom cell renderer, but it appears the cell renderer method "getTableCellRendererComponent" is never called. (I tested it using System.out.println();) Here is my code for setting the cell renderer and the contents of the first column:

MonthYearTableCellRenderer renderer = new MonthYearTableCellRenderer();
tblView.setDefaultRenderer(Date.class, renderer);
for(int i = 0; i < 60; i++){
Calendar cal = Calendar.getInstance();
cal.set(Calendar.DAY_OF_MONTH, 1);
cal.add(Calendar.MONTH, i);
tableModel.setValueAt(cal.getTime(), i, 0);
}

The Date objects are set into the cells of column 0 correctly. The table shows the result of the "toString()" method for each cell in that column.

Swing/AWT/SWT :: Color To Persist In Cell Of Jtable After ComboBox Selection

public TableCellEditor getCellEditor(int row, int col)

JComboBox<?> combo = new JComboBox<Object>(getPickListEntries());
combo.setRenderer(new PickListRenderer(combo));

Swing/AWT/SWT :: JTable Cell Renderer Causing Program To Go Black When Minimized

Aug 25, 2014

I'm making a program that selects classes from a database via a jcombo box and then populates a time table with the class times.

I've used a custom cellrenderer that extends DefaultTableCellRenderer to text wrap the information and change the background of the cells.

It works but when i minimize the program it goes all black and if I double click I get a new JTextArea opening up on the timetable and when I minimize the program and go to open it again i get an "Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException" and the cell render seems to be called again even though i haven't rerun the program.

This is the cell renderer that I built

public class TimesTableCellRenderer extends DefaultTableCellRenderer {
private int minHeight = -1;
private final JLabel label = new JLabel();
private final JTextArea textArea = new JTextArea();
public TimesTableCellRenderer(){
super();
textArea.setLineWrap(true);

Swing/AWT/SWT :: How To Change Color Of Column Header When Cell Is Clicked In JTable

(Just like in MS Excel - preview attached) Now I want to do the same to the column header(i.e. A,B,C,D....etc) . How can I do it?

private void formWindowOpened(java.awt.event.WindowEvent evt) {
setLocationRelativeTo(null);
int rowNum = sheet.getRowCount();
for(int i=0; i<rowNum; i++){
sheet.setValueAt(i+1, i, 0);

JavaFX 2.0 :: How To Prevent User From Leaving Tableview Editing Cell In Case Of Errors

May 14, 2014

I have a TableCell that will hold numbers in a tableview. All is working work nicely, but I want the following behavior:
 
- when the user begins to edit such a cell, if it doesn't enter a number, the cell will not call commitEdit, but rather display a red border and prevent the user from changing the focus to anything else until he either: enters a correct number or presses ESC.
 
I don't know how to keep the user in that editting cell if while he has an incorect number. Currently he can click other row/control and he will break the edditing state. I repeat, I don't want the user to be able to click on any row/control until he has a correct number.

Here is my cell implementation:
 
public class EditableIntegerCell extends TableCell<Person, Integer> {
    private TextField textField;
    @Override
    public void startEdit() {
        if (!isEmpty()) {
            super.startEdit();
            createTextField();
            setText(null);

Swing/AWT/SWT :: Fitting Dynamic JTable Inside A Dialog Or Frame?

Apr 22, 2014

I want to calculate the height of a dialog that contain only a table depending on how many rows that table it has so I'm using the cross multiplication rule.For example i check initially that my table is well fitting into the dialog(Without space at the bottom) for some value and after that i use the cross multiplication rule because data are dynamic.But unfortunately this rule does not solve the problem.What's the best rule for fitting a dynamic table inside a dialog or a frame? Here is my code.

public class FlowLayoutChangingGap {
public static void main(String[] args) {
// just for testing perpose but data are getting from database and it's dynamic
Object[][] data = {
{ "Kathy", "Smith", "Snowboarding", new Integer(5) },
{ "John", "Doe", "Rowing", new Integer(3) },

Key Binding JTable Cell Entries

Jul 8, 2014

I have an editable JTable that has a lot of JComboBox's as cell entries. I would like to be able to "arrow over" to said cell, and with a pressing of either a numerical button or by typing the first letter of the String selection (possibly followed by a second), be able to select the appropriate selection from the cell's JComboBox. I have tried to add a key listener to the JComboBox itself, which works given that I click on said cell and show its menu.

How would I go about ensuring that, when focus is on the cell itself, and I start typing, the appropriate selection is chosen?? (I think this might get into key binding, but I don't know if I have to try it from the scope of JTable, or from that JTable's TableModel (which I have made my custom version of).

Here is what I have so far (everything but SandwichNumber, SandwichName, and Oregano uses JComboBox): [URL] ...., how would I do such key binding?

Custom Jtable Cell Editor Throwing Illegal Component State Exception

Jul 10, 2014

I've come across an interesting problem when using a Jcombobox as a custom cell editor(and renderer) in a jtable. I was hoping to add a keybinding in order to display the dropdown of the combobox instead of having to click on it however, when I make a call to showPopup() I get:

Exception in thread "AWT-EventQueue-0" java.awt.IllegalComponentStateException: component must be showing on the screen to determine its location Which is strange as my jtable is visible and the editor/renderer seems to be working fine.

Here's the cell editor + renderer I'm using:

class MyComboBoxRenderer extends JComboBox implements TableCellRenderer {
public MyComboBoxRenderer(String[] items) {
super(items);
} public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,
boolean hasFocus, int row, int column) {
if (isSelected) {
setForeground(table.getSelectionForeground());

Swing/AWT/SWT :: Moving Image Left Or Right

Mar 11, 2014

I can't find any resource on the net about a simple Java code just to move a gif image left or right. I've already accomplished the up, down, and center and they're working fine, thus, I'm still struggling with moving the image left or right. Here's the code.

public class MoveIt extends Applet implements ActionListener
{
private Image cup;
private Panel keypad;
public int top = 10;
public int left = 10;

[Code] ....

I remember in Visual BASIC it's easily achieved by NameOfImage.left = NameOfImage.left - 10 to move left and NameOfImage.left = NameOfImage.left + 10.
