JSplitPaneがあり、
ただし、Netbeans が Java でコンパイルされているかどうかはわかりません (Eclipse と比較して)
編集I'd like to add a listener on it.
JSplitPane に PropertyChangeListener を追加し、
いくつかの便利な方法がありますif (propertyName.equals(JSplitPane.XxxXxx))
ネストされた JSplitPane の通知、各 JSplitPane のリスナーを個別に追加する必要があります
例えば
.
import java.awt.Dimension;
import java.awt.GridLayout;
import java.beans.PropertyChangeEvent;
import java.beans.PropertyChangeListener;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JSplitPane;
import javax.swing.JTable;
public class JSplitPaneToy {
public static void main(String[] args) {
JSplitPane sp = new JSplitPane(JSplitPane.VERTICAL_SPLIT, makePanel(), makePanel());
JPanel pnl = new JPanel();
pnl.setLayout(new GridLayout(4, 1, 10, 10));
pnl.add(makePanel());
pnl.add(makePanel());
pnl.add(makePanel());
pnl.add(makePanel());
PropertyChangeListener propertyChangeListener = new PropertyChangeListener() {
public void propertyChange(PropertyChangeEvent changeEvent) {
JSplitPane sourceSplitPane = (JSplitPane) changeEvent.getSource();
String propertyName = changeEvent.getPropertyName();
if (propertyName.equals(JSplitPane.LAST_DIVIDER_LOCATION_PROPERTY)) {
int current = sourceSplitPane.getDividerLocation();
System.out.println("Current: " + current);
Integer last = (Integer) changeEvent.getNewValue();
System.out.println("Last: " + last);
Integer priorLast = (Integer) changeEvent.getOldValue();
System.out.println("Prior last: " + priorLast);
}else if (propertyName.equals(JSplitPane.RESIZE_WEIGHT_PROPERTY)) {
int current = sourceSplitPane.getDividerLocation();
System.out.println("Current: " + current);
Integer last = (Integer) changeEvent.getNewValue();
System.out.println("Last: " + last);
Integer priorLast = (Integer) changeEvent.getOldValue();
System.out.println("Prior last: " + priorLast);
}
}
};
sp.addPropertyChangeListener(propertyChangeListener);
JFrame frame = new JFrame("JSplitPane Toy");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new GridLayout(0, 2, 10, 10));
frame.add(sp);
frame.add(pnl);
frame.pack();
frame.setVisible(true);
}
private static JScrollPane makePanel() {
JScrollPane pane = new JScrollPane(new JTable(
new Object[][]{{0, 1, 2}, {1, 2, 3}, {2, 3, 4}}, new Object[]{1, 2, 3}));
pane.setPreferredSize(new Dimension(200, 100));
return pane;
}
