问题描述
这是从序列化数据重建我的JTable的方式:
This is how my JTable is reconstructed from the serialized data:
table = new JTable(){
public boolean isCellEditable(int arg0, int arg1) {
return true;
}
};
table.addMouseListener(this);
table.addFocusListener(this);
int width = HCAConstants.hcaGuiFuzzyTableWidth;
int tableRowHeight = HCAConstants.hcaGuiFuzzyTableRowHeight;
table.putClientProperty("cancelEditOnFocusLost", Boolean.TRUE);
table.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
table.setModel(new MBFTableModel(data[currentH.Int][currentF.Int]));
TableColumn col = table.getColumnModel().getColumn(0);
col.setPreferredWidth(width);}
table.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT)
.put(KeyStroke.getKeyStroke(KeyEvent.VK_TAB, 0), "none");
table.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT)
.put(KeyStroke.getKeyStroke(KeyEvent.VK_TAB, InputEvent.SHIFT_DOWN_MASK), "none");
table.setCellSelectionEnabled(true);
KeyStroke tab = KeyStroke.getKeyStroke(KeyEvent.VK_TAB, 0);
InputMap map = table.getInputMap(JTable.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
map.put(tab, "selectNextRowCell");
table.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT)
.put(KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE, 0), "none");
table.setEnabled(true);
table.setDefaultRenderer(FuzzyDat.class,new FuzzyDatRender());
table.setDefaultEditor(FuzzyDat.class, new FuzzyDatEditor(currentF,(LoadToTable)this));
table.setDefaultRenderer(MinMax.class, new MinMaxRender());
table.setDefaultEditor(MinMax.class, new MinMaxEditor());
table.setRowSelectionAllowed(true);
table.setColumnSelectionAllowed(true);
table.setRowHeight(tableRowHeight);
我的情况是这样的:每当我第一次单击单元格的滑块时，它都不会响应；在第二次单击时，组件会做出响应，然后滑块会在第一次单击时做出响应.
My Scenario is this: Whenever I click on the cell's slider for the first time, it does not respond; on the second click, the component responds and thereafter the slider responds to the first click.
如何使滑块仅与第一次单击交互，而不是与最初单击两次交互.
How can make the slider interactive with the first click only rather than clicking twice initially.
DefaultCellEditor 具有三个默认构造函数:JCheckBox，JComboBox和JTextField；但是我需要为JSlider覆盖此构造函数.我怎样才能做到这一点?这有必要吗?建议使用setClickCountToStart(1).
The DefaultCellEditor has three default constructors: JCheckBox, JComboBox and JTextField; but I need to override this constructor for JSlider. How can I achieve this? Is this necessary? It was suggested that I use setClickCountToStart(1).
推荐答案
也许SliderColumn或SpinnerColumn之一可能会有所帮助:
Maybe one of SliderColumn or SpinnerColumn may help:
SliderColumn:
SliderColumn:
import java.awt.*;
import java.util.EventObject;
import javax.swing.*;
import javax.swing.border.*;
import javax.swing.table.*;
public class SliderColumn extends AbstractCellEditor
implements TableCellEditor, TableCellRenderer {
private JSlider editSlider, renderSlider;
private Border originalBorder;
public SliderColumn(JTable table, int column) {
editSlider = new JSlider();
renderSlider = new JSlider();
originalBorder = editSlider.getBorder();
editSlider.setBorder(new LineBorder(Color.BLUE));
table.getColumnModel().getColumn(column).setCellEditor(this);
Dimension d = renderSlider.getPreferredSize();
table.setRowHeight(d.height);
}
@Override
public Object getCellEditorValue() {
return editSlider.getValue();
}
@Override
public Component getTableCellEditorComponent(JTable table, Object value,
boolean isSelected, int row, int column) {
if (value != null) {
editSlider.setValue((Integer) value);
}
return editSlider;
}
@Override
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
if (hasFocus) {
renderSlider.setBorder(new LineBorder(Color.BLUE));
} else {
renderSlider.setBorder(originalBorder);
}
if (value == null) {
renderSlider.setValue(0);
} else {
int intValue = ((Integer) value).intValue();
renderSlider.setValue(intValue);
}
return renderSlider;
}
@Override
public boolean isCellEditable(EventObject evt) {
return true;
}
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
JFrame frame = new JFrame("SpinnerColumn");
JPanel panel = new JPanel(new GridLayout(1, 1));
JTable table = new JTable(5, 1);
SliderColumn spinnerColumn = new SliderColumn(table, 0);
table.setDefaultRenderer(Object.class, spinnerColumn);
panel.add(table);
frame.setContentPane(panel);
frame.pack();
frame.setVisible(true);

}
});
}
}
SpinnerColumn:
SpinnerColumn:
import java.awt.*;

import javax.swing.border.*;
import javax.swing.table.*;
public class SpinnerColumn extends AbstractCellEditor implements TableCellEditor, TableCellRenderer {

private String[] list;
private Border originalBorder;
public SpinnerColumn(JTable table, int column) {
editSpinner = new JSpinner();
renderSpinner = new JSpinner();
originalBorder = editSpinner.getBorder();
editSpinner.setBorder(new LineBorder(Color.BLUE));
this.table = table;
table.getColumnModel().getColumn(column).setCellEditor(this);
}
public SpinnerColumn(String[] list, JTable table, int column) {
editSpinner = new JSpinner();
editSpinner.setModel(new SpinnerListModel(list));
renderSpinner = new JSpinner();
originalBorder = editSpinner.getBorder();
editSpinner.setBorder(new LineBorder(Color.BLUE));
this.list = list;
this.table = table;
table.getColumnModel().getColumn(column).setCellEditor(this);
}
@Override
public Object getCellEditorValue() {
return editSpinner.getValue();
}
@Override
public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected,
int row, int column) {
if (list != null) {
editSpinner.setValue(list[0]);
} else {
editSpinner.setValue(0);
}
if (value != null) {
editSpinner.setValue(value);
}
return editSpinner;
}
@Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,
boolean hasFocus, int row, int column) {
if (hasFocus) {
renderSpinner.setBorder(new LineBorder(Color.BLUE));
} else {
renderSpinner.setBorder(originalBorder);
}
// *** here's where we set the spinner's value
if (value == null) {
renderSpinner.setValue(0);
} else {
int intValue = ((Integer) value).intValue();
renderSpinner.setValue(intValue);
}
return renderSpinner;
}
@Override
public boolean isCellEditable(EventObject evt) {
return true;
}
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
JFrame frame = new JFrame("SpinnerColumn");
JPanel panel = new JPanel(new GridLayout(1, 1));
JTable table = new JTable(5, 1);
SpinnerColumn spinnerColumn = new SpinnerColumn(table, 0);
table.setDefaultRenderer(Object.class, spinnerColumn);
panel.add(table);
frame.setContentPane(panel);
frame.pack();
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
});
}
}
