Mouse Event not working when clicking JTable

I created a simple mouse event. When the user clicks the JTable it will fetch the records in the JTable and display them in the JTextField. In this case I am trying to display the ID from the Table into the Text Field.
public void fetchRec() {
xtable.addMouseListener(new MouseAdapter() {
public void rowClicked(MouseEvent evt){
xtable =(JTable) evt.getSource();
int row = xtable.rowAtPoint( evt.getPoint() );
int column = xtable.columnAtPoint( evt.getPoint() );
String s=xtable.getModel().getValueAt(row, column)+"";
idLabelField.setText(s);
}
});
}
I am calling the method here but it keeps telling me that rowClicked method is unused. I don't understand how its unused? Everything else I am calling is working except this.
public void bookDimensions() throws Exception {
addTextLabels();
addTextFields();
addPanelButtons();
addRecord();
addTable();
fetchRec();
}

Turn on cell selection and listen to the selection model instead of mouse events. See java: how to select only one cell in a jtable and not the whole row

Selecting all text when clicking or pressing TAB on JTextField

How can I set up the JTextField so that, when the user clicks on it or presses the TAB key, the text of JTextField is selected?

Add a FocusListener to the JTextField, and in focusGained(), call selectAll().
In code, this looks like this:
yourTextField.addFocusListener(new FocusListener() {
#Override
public void focusGained(FocusEvent e) {
((JTextField)e.getSource()).selectAll();
}
#Override
public void focusLost(FocusEvent e) {}
});

You must set the selection start to the begining it is on end by default.
This is he shortest implementation possible.
jTextField1.setSelectionStart(0);

Select All text inside CellEditor

I have a tableViewer where I can edit 1 column. Everytime the cellEditor from this column gains focus I want all the text that is displayed to be selected. In a normal SWT text control, we would just do text.selectAll(); , so I've set this listener for the the cellEditor inside the column EditingSupport class:
editor.getControl().addFocusListener(new FocusListener() {
#Override
public void focusGained(FocusEvent e) {
Text text = (Text) editor.getControl();
text.selectAll();
}
});
I know I can cast the cellEditor control to a Text input because I've tested it with a normal setText(); and it Works! However, the selectAll(); is not working, how can I fix this?
SOLUTION
I found the error, the code in my question above works perfectly, the reason I wasn't able to see the selectAll(); doing something is in this method:
#Override
protected Object getValue(Object element) {
String valor = MathUTILS.getBigDecimalFormatted(((ColaboradoresDespesasDocumentosLinhas) element).getValor(), PatternVARS.PATTERN_BIGDECIMAL_MILLION);
Text text = InterfaceFormatUTILS.getControlNumberFormat(editor, PatternVARS.PATTERN_BIGDECIMAL_BILLION);
return valor;
}
This is also a method from the EditingSupport class, and for some reason formatting the text control (Text text = InterfaceFormatUTILS.getControlNumberFormat(editor, PatternVARS.PATTERN_BIGDECIMAL_BILLION);) deselects all the text. Also, doing the selectAll(); in this method doesn't work..

JTable does not accept text from Windows IME keyboard directly [duplicate]

I have a JTable with editable cells. When I click in a cell, it enters edit mode; the same happens when I'm moving through cell using the directional arrows.
Now I want to select the cell instead of start editing, and edit the cell only when the Enter key is pressed.
If any other information is needed, please just ask for it.
Edit: Action for Enter key
class EnterAction extends AbstractAction {
#Override
public void actionPerformed(ActionEvent e) {
JTable tbl = (JTable) e.getSource();
tbl.editCellAt(tbl.getSelectedRow(), tbl.getSelectedColumn());
if (tbl.getEditorComponent() != null) {
tbl.getEditorComponent().requestFocus();
}
}
}
Now this is for left arrow action the rest of 3 are not hard to deduce from this one:
class LeftAction extends AbstractAction {
#Override
public void actionPerformed(ActionEvent e) {
JTable tbl = (JTable)e.getSource();
tbl.requestFocus();
tbl.changeSelection(tbl.getSelectedRow(), tbl.getSelectedColumn() > 0 ? tbl.getSelectedColumn()-1:tbl.getSelectedColumn(), false, false);
if(tbl.getCellEditor()!=null)
tbl.getCellEditor().stopCellEditing();
}
}
And this is how you bind this actions:
final String solve = "Solve";
KeyStroke enter = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0);
table.getInputMap(JTable.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT).put(enter, solve);
table.getActionMap().put(solve, new EnterAction());
final String sel = "Sel";
KeyStroke arrow = KeyStroke.getKeyStroke(KeyEvent.VK_LEFT, 0);
table.getInputMap(JTable.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT).put(arrow, sel);
table.getActionMap().put(sel, new LeftAction());
Oh,i almost forgot,to select the cell instead of edit on Mouse Click:
public static MouseListener mAdapterTable = new MouseListener()
{
#Override
public void mousePressed(MouseEvent e)
{
JTable tbl=((JTable)e.getComponent());
if(tbl.isEditing())
{
tbl.getCellEditor().stopCellEditing();
}
}
#Override
public void mouseClicked(MouseEvent e) {
JTable tbl=((JTable)e.getComponent());
if(tbl.isEditing() )
tbl.getCellEditor().stopCellEditing();
}
#Override
public void mouseReleased(MouseEvent e) {
JTable tbl=((JTable)e.getComponent());
if(tbl.isEditing() )
tbl.getCellEditor().stopCellEditing();
}
};
The EventListner must be added to table like so:
table.addMouseListener(mAdapterTable);

Use Key Bindings for this. Most Look & Feel implementations already bind F2 to the table's startEditing action, but you add a different binding:
tree.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), "startEditing");
This will effectively replace the previous binding of Enter to the table's selectNextRowCell action.

Here is what i would do:
First enable the single cell selection for the JTable
Create a KeyAdapter or KeyListener for the JTable or for the JPanel,
what contains your table.
In the KeyAdapter's keyPressed() method enter the edit mode of the
selected cell, something like this:
http://www.exampledepot.com/egs/javax.swing.table/StopEdit.html
You can check in the keyPressed() method, if the user pressed the right button for editing. I'm not sure, if the normal (double click) editing is disabled in your table, then what happens, if you try to edit it programmatically, but if it doesn't work, then you can enable the editing on the selected cell, when the user presses the edit button, then when he/she finished, disable it again.

How do I get the input from a textfield in a netbeans RCP app?

I am making a text based game in Java. I have a text field, enter button, and a label.
What code do i use to scan the text field once the button is clicked and respond?
So that if I type in (launch missile) the label should say (missile launched).
I will be listening to a button actionperformed or maybe a mouseclick event . Something like this
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
if (Text field says: launch missile)
{print on label:Missile launched}
or
if (text field says: invade)
{Print on label: Invasion started}

you can read the text field using
textField1.getText()
to compare, use
if (textField1.getText().equals("launch missle"))
{
//do something
}
similarly, to set the label's text, use
label1.setText("Missle launched");
I suggest reading more about Java flow control.

try
JButton launch=new JButton(new AbstractAction("Launch")
{
#Override
public void actionPerformed(ActionEvent e)
{
yourLabel.setText("Missile Launched");
}
});
