「強調表示 (拡張)」の下の SwingX ショーケースのように、内部の値に関連して org.jdesktop.swingx.JXTreeTable のセルを強調表示したい:
ショーケースにはいくつかのコードが提供されていますが、動作させることができず、何も強調表示されません。蛍光ペンが値にバインドされる場所がよくわかりません (提供されたコードが完全ではない可能性があります)。また、利用可能なドキュメントはありません。
ショーケースのコードは次のとおりです。
これは私のコードです:
TreeFrame.java
private void initialize( ProfileThread profileThread )
{
try
{
UIManager.setLookAndFeel( UIManager.getSystemLookAndFeelClassName() );
}
catch ( Exception e )
{
e.printStackTrace();
}
setBounds( 0, 0, 800, 600 );
setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
setTitle( "ProfileLog" );
NoRootTreeTableModel model = new NoRootTreeTableModel(
profileThread.getProfileThreadElements(), this );
JXTreeTable treeTable = new JXTreeTable( model );
MattePainter painter = new MattePainter( PaintUtils.setAlpha( Color.RED, 125 ) );
highlighter = new RelativePainterHighlighter( painter );
highlighter.setHighlightPredicate( HighlightPredicate.ALWAYS );
treeTable.addHighlighter( highlighter );
JScrollPane treeView = new JScrollPane( treeTable );
getContentPane().add( treeView );
setVisible( true );
}
public void setCurrentDuration( long duration )
{
DurationRelativizer relativizer = createDurationRelativizer( duration );
highlighter.setRelativizer( relativizer );
}
/**
* Creates and returns a relativizer with the given intermediate value.
*
*/
private DurationRelativizer createDurationRelativizer( long duration )
{
return new DurationRelativizer( 0, true, 15000, duration );
}
public static class DurationRelativizer extends NumberRelativizer
{
public DurationRelativizer( int column, boolean spreadColumns, Number max, Number current )
{
super( column, spreadColumns, max, current );
}
@Override
protected Number getNumber( ComponentAdapter adapter )
{
if ( !( adapter.getValue( getValueColumn() ) instanceof ProfileThreadElement ) )
{
return null;
}
return ( (ProfileThreadElement) adapter.getValue( getValueColumn() ) ).getDuration();
}
}
例から関連するコードを取り出し、要件に合わせて変更しました。私の RelativePainterHighlighter クラスは、ショーケースとまったく同じです。
これは私の ProfileThreadElement クラスです:
ProfileThreadElement.java
import java.util.ArrayList;
import java.util.Date;
import java.util.Enumeration;
import java.util.Iterator;
import java.util.List;
import javax.swing.tree.TreeNode;
public class ProfileThreadElement implements TreeNode
{
private Date start;
private Date end;
private long duration;
private String text;
private String result;
private ProfileThreadElement parent;
private List<ProfileThreadElement> children;
/**
* Instantiates a new profile thread element.
*
* @param timestamp the timestamp
* @param text the text
*/
public ProfileThreadElement( Date timestamp, String text )
{
super();
this.start = timestamp;
this.text = text;
this.children = new ArrayList<ProfileThreadElement>();
}
/**
* Close.
*
* @param timestamp the timestamp
* @param duration the duration
* @param result the result
*/
public void close( Date timestamp, long duration, String result )
{
this.end = timestamp;
this.duration = duration;
this.result = result;
}
/**
* Adds the children.
*
* @param child the child
*/
public void addChildren( ProfileThreadElement child )
{
// if ( children == null )
// {
// children = new ArrayList<ProfileThreadElement>();
// }
children.add( child );
child.setParent( this );
}
/**
* @param parent the parent to set
*/
void setParent( ProfileThreadElement parent )
{
this.parent = parent;
}
/**
* Checks if is open.
*
* @return true, if is open
*/
public boolean isOpen()
{
return end == null;
}
/**
* @return the start
*/
public Date getStart()
{
return start;
}
/**
* @return the end
*/
public Date getEnd()
{
return end;
}
/**
* @return the duration
*/
public long getDuration()
{
return duration;
}
/**
* @return the text
*/
public String getText()
{
return text;
}
/**
* @return the result
*/
public String getResult()
{
return result;
}
/**
* @return the parent
*/
public ProfileThreadElement getParent()
{
return parent;
}
/**
* @return the children
*/
public List<ProfileThreadElement> getChildren()
{
return children;
}
/*
* (non-Javadoc)
*
* @see javax.swing.tree.TreeNode#children()
*/
@Override
public Enumeration<ProfileThreadElement> children()
{
return new Enumeration<ProfileThreadElement>()
{
Iterator<ProfileThreadElement> iterator = children.iterator();
@Override
public boolean hasMoreElements()
{
return iterator.hasNext();
}
@Override
public ProfileThreadElement nextElement()
{
return iterator.next();
}
};
}
/*
* (non-Javadoc)
*
* @see javax.swing.tree.TreeNode#getAllowsChildren()
*/
@Override
public boolean getAllowsChildren()
{
return !children.isEmpty();
}
/*
* (non-Javadoc)
*
* @see javax.swing.tree.TreeNode#getChildAt(int)
*/
@Override
public TreeNode getChildAt( int childIndex )
{
return children.get( childIndex );
}
/*
* (non-Javadoc)
*
* @see javax.swing.tree.TreeNode#getChildCount()
*/
@Override
public int getChildCount()
{
return children.size();
}
/*
* (non-Javadoc)
*
* @see javax.swing.tree.TreeNode#getIndex(javax.swing.tree.TreeNode)
*/
@Override
public int getIndex( TreeNode node )
{
return children.indexOf( node );
}
/*
* (non-Javadoc)
*
* @see javax.swing.tree.TreeNode#isLeaf()
*/
@Override
public boolean isLeaf()
{
return children.isEmpty();
}
@Override
public String toString()
{
StringBuffer sb = new StringBuffer();
sb.append( duration );
sb.append( " ms " );
sb.append( text );
return sb.toString();
}
}
そして私のツリーテーブルモデル:
NoRootTreeTableModel.java
public class NoRootTreeTableModel extends AbstractTreeTableModel
{
private final static String[] COLUMN_NAMES = { "Duration (ms)", "Function Call", "Class" };
private List<ProfileThreadElement> profileThreadElements;
private TreeFrame frame;
public NoRootTreeTableModel( List<ProfileThreadElement> profileThreadElements, TreeFrame frame )
{
super( new Object() );
this.profileThreadElements = profileThreadElements;
this.frame = frame;
}
@Override
public int getColumnCount()
{
return COLUMN_NAMES.length;
}
@Override
public String getColumnName( int column )
{
return COLUMN_NAMES[column];
}
@Override
public boolean isCellEditable( Object node, int column )
{
return false;
}
@Override
public Object getValueAt( Object node, int column )
{
if ( node instanceof ProfileThreadElement )
{
Matcher matcher;
Pattern pattern;
ProfileThreadElement element = (ProfileThreadElement) node;
switch ( column )
{
case 0: // duration
frame.setCurrentDuration( element.getDuration() );
return element.getDuration();
case 1: // function
pattern = Pattern.compile( "\\.[a-z][a-zA-Z]+\\(.*\\)" );
matcher = pattern.matcher( element.getText() );
if ( matcher.find() )
return matcher.group().substring( 1 );
else
return "";
case 2: // class
pattern = Pattern.compile( ".+?(?=\\.[a-z][a-zA-Z]+\\(.*\\))" );
matcher = pattern.matcher( element.getText() );
if ( matcher.find() )
return matcher.group().replace( "class ", "" );
else
return "";
}
}
return null;
}
@Override
public int getChildCount( Object parent )
{
if ( parent instanceof ProfileThreadElement )
{
ProfileThreadElement element = (ProfileThreadElement) parent;
return element.getChildren().size();
}
return profileThreadElements.size();
}
@Override
public Object getChild( Object parent, int index )
{
if ( parent instanceof ProfileThreadElement )
{
ProfileThreadElement element = (ProfileThreadElement) parent;
return element.getChildren().get( index );
}
return profileThreadElements.get( index );
}
@Override
public int getIndexOfChild( Object parent, Object child )
{
ProfileThreadElement element = (ProfileThreadElement) parent;
return element.getChildren().indexOf( (ProfileThreadElement) child );
}
}
最大の問題は、 TreeFrame.setCurrentDuration(...) メソッドをどこで呼び出すかが分からないことだと思います。これは、ショーケースのデモにはありません。相対的な強調表示が機能する人はいますか?
どんな助けでも大歓迎です、事前に感謝します!
