hi, ich hab probleme mit den layoutmanagern. ich kann einstellen, was ich will, nichts funktioniert. die elemente werde alle in einer reihe angezeigt.
Code:
public class OptionGUI implements ActionListener
{
//Tab Panel
private JTabbedPane tabbedPane = new JTabbedPane();
//Inhalter der Tabs
private JPanel internetPanel = new JPanel();
private JPanel fieldPanel = new JPanel();
private JPanel tablePanel = new JPanel();
//Inhalt für Internet Panel
private JCheckBox checkProxy = new JCheckBox("Proxy verwenden");
private JTextField txtProxy = new JTextField(30);
private JTextField txtPort = new JTextField(5);
private JLabel lblProxy = new JLabel("Proxy");
private JLabel lblPort = new JLabel("Port");
private JFrame optionWindow = new JFrame("Optionen");
private JPanel createInternetPanel()
{
internetPanel.setLayout(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
c.fill = GridBagConstraints.HORIZONTAL;
c.gridx = 1;
c.gridy = 1;
c.gridwidth = 5;
checkProxy.setVisible(true);
checkProxy.addActionListener(this);
internetPanel.add(checkProxy);
c.gridx = 1;
c.gridy = 2;
c.gridwidth = 3;
txtPort.setEnabled(false);
txtPort.setVisible(true);
internetPanel.add(txtProxy);
c.gridx = 5;
c.gridy = 3;
c.gridwidth = 2;
txtProxy.setEnabled(false);
txtProxy.setVisible(true);
internetPanel.add(txtPort);
return internetPanel;
}
public void createOptionWindow()
{
tabbedPane.addTab("Internet", createInternetPanel());
tabbedPane.addTab("Felder", fieldPanel);
tabbedPane.addTab("Tabelle", tablePanel);
tabbedPane.setVisible(true);
optionWindow.add(tabbedPane);
optionWindow.setSize(600, 400);
optionWindow.pack();
optionWindow.setVisible(true);
}
public void actionPerformed(ActionEvent e)
{
if(e.getActionCommand().equals("Proxy verwenden")){
if(checkProxy.isSelected())
{
txtPort.setEnabled(true);
txtProxy.setEnabled(true);
}
else
{
txtPort.setEnabled(false);
txtProxy.setEnabled(false);
}
}
}
}
