如何在我使用JTabbedPane和面板布局的swing应用程序中对齐JLabel是FlowLayout
public class RoteLearnerTabbedPanePage extends JFrame{
private static final long serialVersionUID = 1L;
private JTabbedPane tabbedPane;
private JPanel panel1;
private JPanel transientPanel;
private JPanel nonTransientPanel;
ReadXml rx=new ReadXml();
Set<String> primaryKeys = rx.getPrimaryKeysOfGuiAttributes();
public RoteLearnerTabbedPanePage() throws IOException, SAXException, ErrorCondition
{
tabbedPane=new JTabbedPane();
FlowLayout fl=new FlowLayout();
Document doc=rx.readXmlFile();
Hashtable<String,String> mainclasnames=rx.getMainClassNames(doc, doc.getChildNodes());
Set<XmlClass> guiAttrVals=rx.getGuiAttributeValues(doc, doc.getChildNodes());
int j=-1;
Iterator<Entry<String, String>> mainclass_it = mainclasnames.entrySet().iterator();
while(mainclass_it.hasNext())
{
Entry<String, String> classDet = mainclass_it.next();
String classname = classDet.getValue();
final Hashtable<JLabel,JTextField> uiParams=new Hashtable<JLabel,JTextField>();
JPanel buttons=new JPanel();
JButton buttonLearn = new JButton("Learn");
panel1= new JPanel();
transientPanel=new JPanel(new GridBagLayout());
nonTransientPanel=new JPanel(new GridBagLayout());
GridBagConstraints constraints = new GridBagConstraints();
Iterator<XmlClass> guiItr=guiAttrVals.iterator();
while(guiItr.hasNext())
{
XmlClass xmlclasss=guiItr.next();
if(classname.equals(xmlclasss.getName()))
{
Set<XmlAttributes> xmlAttrs=xmlclasss.getAttributes();
Iterator<XmlAttributes> xmlattrItr=xmlAttrs.iterator();
while(xmlattrItr.hasNext())
{
XmlAttributes xa=xmlattrItr.next();
String attrname=xa.getName();
String isTransient=xa.isTransientAttr();
if(isTransient.equals("false"))
{
constraints.anchor = GridBagConstraints.NORTH;
constraints.insets = new Insets(10, 10, 10, 10);
JLabel name = new JLabel(attrname);
//name.setBounds( 10, 15, 150, 20 );
JTextField value = new JTextField(20);
//value.setBounds( 10, 15, 150, 20 );
constraints.gridx = 0;
constraints.gridy = ++j;
if(primaryKeys.contains(name.getText()))
{
name.setForeground(Color.RED);
}
else
{
name.setForeground(Color.BLUE);
}
nonTransientPanel.add(name,constraints);
nonTransientPanel.add(value);
uiParams.put(name, value);
nonTransientPanel.setBorder(BorderFactory.createTitledBorder(BorderFactory.createEtchedBorder(), "Non Transient Attributes"));
nonTransientPanel.setLayout(fl);
panel1.add(nonTransientPanel);
}
else
{
constraints.anchor = GridBagConstraints.NORTH;
constraints.insets = new Insets(10, 10, 10, 10);
JLabel name = new JLabel(attrname);
//name.setBounds( 10, 15, 150, 20 );
JTextField value = new JTextField(20);
//value.setBounds( 10, 35, 150, 20 );
constraints.gridx = 0;
constraints.gridy = ++j;
if(primaryKeys.contains(name.getText()))
{
name.setForeground(Color.RED);
}
else
{
name.setForeground(Color.BLUE);
}
transientPanel.add(name,constraints);
transientPanel.add(value);
uiParams.put(name, value);
transientPanel.setBorder(BorderFactory.createTitledBorder(BorderFactory.createEtchedBorder(), "Transient Attributes"));
transientPanel.setLayout(fl);
panel1.add(transientPanel);
}
}
constraints.gridx = 0;
constraints.gridy = ++j;
constraints.gridwidth = 2;
constraints.anchor = GridBagConstraints.SOUTH;
panel1.setSize(400, 400);
panel1.setLayout(fl);
tabbedPane.addTab(classname, panel1);
}
}
buttons.add(buttonLearn, constraints);
panel1.add(buttons);
}
setTitle( "Rote Learner Form" );
setSize(500, 500);
JPanel topPanel = new JPanel();
topPanel.setLayout(new BorderLayout());
getContentPane().add( topPanel );
// Create the tab pages
topPanel.add( tabbedPane, BorderLayout.CENTER );
}
这就是我使用JTabbedPane显示两种形式的方式。
- 如何缩进JLabel以使其看起来像标准表单？
有人能回答这个问题吗？迫切需要..提前谢谢.. 我使用了JTabbedPane和一个外部Jpanel，里面有两个JPanels TransietnPanel和nonGTransientPanel。此外部面板已添加到JTabedPane。
这是我得到的输出
这就是我想要的样子。
