1) line frame.setVisible(true); must be last line for JFrame constuctor 2) never use Graphics g = frame.getGraphics(); 3) use [URL="http://stackoverflow.com/a/7940227/714968"]KeyBindings[/URL] rather than KeyListener

I think that nothing complicated in this case [URL="http://docs.oracle.com/javase/6/docs/api/javax/swing/table/DefaultTableModel.html"]public class DefaultTableModel extends AbstractTableModel implements Serializable[/URL] you have to add and override this method for removeRow in your AbstractTableModel [CODE]public void removeRowAt(int row) { data.removeElementAt(row); //fireTableDataChanged(); fireTableRowsDeleted(row - 1, data.size() - 1); }[/CODE]

1) place this code line [B]panel.setLayout(null); [/B] before placing JComponent 2) variables [B]JScrollPane scrollpane;[/B] and [B] JScrollPane scrollpane1;[/B] aren't initialized and rest of JComponents

you can't put Image as background to [URL="http://docs.oracle.com/javase/tutorial/uiswing/components/frame.html"]JFrame[/URL], but 1) ContentPane 2) paintComponent for JPanel / JComponent 3) [URL="http://docs.oracle.com/javase/tutorial/uiswing/components/label.html"]JLabel[/URL] & [URL="http://docs.oracle.com/javase/tutorial/uiswing/components/icon.html"]Icon[/URL] (notice JLabel haven't implemented any LayoutManager, you have to defin for that)

1) wrong that you used code generated by NetBeans 2) fireTableRowsInserted is job for AbstractTableModel, don't call tshi method directly 3) eeerrrgggggggggggt, use DefaultTableModel [CODE]import java.awt.*; import java.awt.event.*; import java.util.Random; import javax.swing.*; import javax.swing.border.LineBorder; import javax.swing.table.DefaultTableModel; import javax.swing.table.TableCellRenderer; public class DefaultTableModelDemo { public static final String[] COLUMN_NAMES = { "Monday", …

@cOrRuPtG3n3t!x what's an aswers is [CODE]maybe you coud try setting the bounds of components by setBounds() and setMaximumSize(Dimension) and even setPreferredSize(Dimension) methods? [/CODE] no never setBounds, this is job for LayoutManager, occasionally you can place that by take Insets, but why not use MigLayout most of LayoutManagers pretty ignored setXxxSize

if you set [B]JTextArea(m, 10, 15);[/B] , then [B]scroll.setSize(500, 500);[/B] is too contraproductive, call for [B]scroll.pack();[/B] before [B]scroll.setVisible(true);[/B] rather than manually set for size on the screen

it too hard to implementing JList & Render with some of dirty hack, use JTable with one Column, 1) JTable with JCheckBox is represented with Boolean value only 2) no required any code for Renderer/Editor, because JTable knows Boolean value 3) JTable must be editable for Editor 4) everything [URL="http://docs.oracle.com/javase/tutorial/uiswing/components/table.html"]here[/URL]
