I am developing an application using jTable
for inventory management.
The action is, by typing the item code in a jTextField
and by pressing Enter key, the details of that code should come to jTable
. And there I have to type the quantity and press Enter to calculate the amount. But now by giving item code the details come to the jTable
, and I can type the quantity, but there by pressing Enter key jTable
focus goes to the next row and no calculation is being done. But by again pressing Enter key on the jTextField
the last entered amount is getting calculated. I don't know how to solve this problem as I am a beginner in Java. I am using MySQL and Java in Netbeans.
I am giving that code below..
Thank You..
jTable1.editCellAt(serialNumber, 2);
jTable1.getCellSelectionEnabled();
value1 = new Double(jTable1.getValueAt(serialNumber, 2).toString());
value = new Double(jTable1.getValueAt(serialNumber, 3).toString());
double result = value1 * value;
jTable1.setValueAt(result, serialNumber, 4);
The JTable is used to display and edit regular two-dimensional tables of cells. See How to Use Tables in The Java Tutorial for task-oriented documentation and examples of using JTable .
A JTable automatically creates renderers for cells which can be called as default renderers. These renderers are based on the data type the cell displays. For example, for a numeric column, JTable creates renderers which display the value as right-aligned.
The JTable class is a part of Java Swing Package and is generally used to display or edit two-dimensional data that is having both rows and columns. It is similar to a spreadsheet. This arranges data in a tabular form.
You can use Java 8 lambda functions:
final String tustakmaad = "Solve";
KeyStroke enter = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0);
panel.getTblBelgetarihiliste().getInputMap(JTable.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT).put(
enter, tustakmaad);
panel.getTblBelgetarihiliste().getActionMap().put(tustakmaad, new DelegateAction(
ae -> eventMytable_enterkey()));
and DelegateAction
class should be like this:
package com.ozpas.entegre.controller;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.AbstractAction;
public class DelegateAction extends AbstractAction {
/**
*
*/
private static final long serialVersionUID = 1L;
ActionListener myaction = (ae) -> {
System.out.println("empty action");
};
public DelegateAction(ActionListener customaction) {
this.myaction = customaction;
}
@Override
public void actionPerformed(ActionEvent e) {
myaction.actionPerformed(e);
}
public ActionListener getMyaction() {
return myaction;
}
public void setMyaction(ActionListener myaction) {
this.myaction = myaction;
}
}
