POanimation in JTable
text
Body
copied!<p>I am trying to put gif image(animated) to a JTable cell, but it's not being displayed. As I have read, JTable component is static and it's required to rewrite rendering.</p> <p>The point is that I have a thread which calculates some data and pastes it to a table cell, while calculating I want to display some rotating wheel. Moreover, I add rows to the table from another separate thread. So, one thread adds a row with some data and another thread calculates data for a cell in the row.</p> <p>Is it possible to add an animation icon into the same cell in each added row? Has anyone ideas how to do it?</p> <p>Upd: Now I can create a row with animated gif, but can't add such rows to a table from a thread</p> <pre><code>public class AnimatedIconTableExample extends JFrame { private static final long serialVersionUID = -1038271613549995183L; public AnimatedIconTableExample() { super("AnimatedIconTable Example"); final Object[][] data = new Object[][] { { "", "", new ImageIcon("src/loading.gif"), "text" } }; final Object[] column = new Object[] { "First", "Second", "Third", "Fourth" }; DefaultTableModel model = new DefaultTableModel() { private static final long serialVersionUID = 31150076182704312L; public int getColumnCount() { return column.length; } public int getRowCount() { return data.length; } public String getColumnName(int col) { return (String) column[col]; } public Object getValueAt(int row, int col) { return data[row][col]; } public Class<?> getColumnClass(int col) { return ImageIcon.class; } }; JTable table = new JTable(model); setImageObserver(table); JScrollPane pane = new JScrollPane(table); getContentPane().add(pane); for (int i = 0; i < 5; i++) { new TableUpdater(model, data).start(); } } private void setImageObserver(JTable table) { TableModel model = table.getModel(); int colCount = model.getColumnCount(); int rowCount = model.getRowCount(); for (int col = 0; col < colCount; col++) { if (ImageIcon.class == model.getColumnClass(col)) { for (int row = 0; row < rowCount; row++) { Object obj = model.getValueAt(row, col); ImageIcon icon = null; if (obj instanceof ImageIcon) icon = (ImageIcon) model.getValueAt(row, col); if (icon != null) { icon.setImageObserver(new CellImageObserver(table, row, col)); } } } } } class CellImageObserver implements ImageObserver { JTable table; int row; int col; CellImageObserver(JTable table, int row, int col) { this.table = table; this.row = row; this.col = col; } public boolean imageUpdate(Image img, int flags, int x, int y, int w, int h) { if ((flags & (FRAMEBITS | ALLBITS)) != 0) { Rectangle rect = table.getCellRect(row, col, false); table.repaint(rect); } return (flags & (ALLBITS | ABORT)) == 0; } } public static void main(String[] args) { AnimatedIconTableExample frame = new AnimatedIconTableExample(); frame.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent e) { System.exit(0); } }); frame.setSize(300, 150); frame.setVisible(true); } } public class TableUpdater extends Thread { private DefaultTableModel model; private Object[][] data; public TableUpdater(DefaultTableModel model, Object[][] data) { this.model = model; this.data = data; } public void run() { try { Thread.sleep(3000); } catch (InterruptedException e) { e.printStackTrace(); } model.addRow(data); } } </code></pre>
