これはこの質問の続きですJava resizing individual components of JPanel今回はフレームにはテーブルとJTextAreaしかありません。テーブルとJTextAreaの間に大きな空の領域が表示されます。これはmyPanel.javaです。JTableポリシー。表の下のgridBagLayoutパネルの空白スペース。
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.JTextArea;
public class myPanel extends JPanel {
public myPanel() { // Creating a vertical Box layout with five sections, placing jpanels there
//First panel with a table
String[] columnNames = {"First", "Second", "Third", "Fourth"};
Object[][] data = {{"11", "12", "13", "Forteen"},{"21", "22", "23", "Twenty four"}};
JScrollPane scrollPane1 = new JScrollPane(new JTable(data, columnNames));
//Second panel with a text area
JTextArea ecnArea = new JTextArea(10, 20);
ecnArea.setText("");
ecnArea.setName("Note");
//ecnArea.setLineWrap(true);
//ecnArea.setWrapStyleWord(true);
JScrollPane myScrollBar = new JScrollPane(ecnArea);
//Placing everything in a container
this.setLayout(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
c.anchor =GridBagConstraints.CENTER;
c.fill = GridBagConstraints.BOTH;
c.weightx = 0.5;
c.weighty=0.5;
c.gridx = 0;
c.gridy = 0;
this.add(scrollPane1, c);
c.gridy++;
this.add(myScrollBar, c);
}
}
なぜそれが表示されますか?どのようにそれを削除するには?
