java - Can't add JTree to JPanel of a JInternalFrame -

-

There are two panels in my JInternalframe. I want to add TopPanel to Jtree to nominate another. But I can not add Jaitari to the top of the panel. Please help me in this piece of code: 

  DefaultMutableTreeNode root = new DefaultMutableTreeNode ("deck"); DefaultMutableTreeNode Item Clubs = New DefaultMutableTreeNode ("Club"); AddAllCard (itemClubs); Root.add (itemClubs); DefaultMutableTreeNode item = New DefaultMutableTreeNode ("Diamonds"); AddAllCard (itemDiamonds); Root.add (itemDiamonds); DefaultMutableTreeNode Itemspads = New DefaultMutableTreeNode ("Spades"); AddAllCard (itemSpades); Root.add (itemSpades); DefaultMutableTreeNode item increases = new DefaultMutableTreeNode ("heart"); AddAllCard (itemHearts); Root.add (itemHearts); Default Trimodel Tree Model = New DefaultTreeModel (Route); Tree = new jetty (tree modal); ScrollPane = new JScrollPane (tree); // scrollPane.setViewportView (tree); . ScrollPane.getViewport () add (tree); TopPanel.add (ScrollPan, Border Layout. CA); TopPanel.setVisible (true); Tree.setVisible (true); Actually, works for me, something that you are not showing us.  
 Consider providing that reflects your problem, resulting in fewer delusions and better responses  
  treeExample   
  Import java.awt.borderLayout; Import java.awt.EventQueue; Import javax.swing.JDesktopPane; Import javax.swing.JFrame; Import javax.swing.JInternalFrame; Import javax.swing.JPanel; Import javax.swing.JScrollPane; Import javax.swing.JTree; Import javax.swing.UIManager; Import javax.swing.UnsupportedLookAndFeelException; Import javax.swing.tree.DefaultMutableTreeNode; Import javax.swing.tree.DefaultTreeModel; Public square tree test {public static zero main (string [] args) {new tree test (); } Public Tree Test () {EventQueue.invokeLater {@Override Public Zero () {{UIManager.setLookAndFeel (UIManager.getSystemLookAndFeelClassName ())}} Hold (ClassNotFoundException | InstantiationException | Invalid AccessException | UnsupportedLookAndFeelException East) {ex .printStackTrace ();} JDesktopPane desktopPane = new JDesktopPane (); JInternalFrame inFrame = New JInternalFrame ("Tree", True Truth, True, True); InFrame.add (New TestPane ()); InFrame.pack (); InFrame .setVisible (true); DesktopPane.add (inFrame); JFrame frame = new JFrame ("test"); Frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); Frame.add (desktopPane); Frame.setSize (200, 200); Frame .setLocationRelat Iveto (zero); Frame.setVisible (true); }}); } Public Square TestPane sets JPanel {Public TestPane ()} {Set Layout (New border layout ()); DefaultMutableTreeNode root = new DefaultMutableTreeNode ("deck"); DefaultMutableTreeNode Item Clubs = New DefaultMutableTreeNode ("Club"); Root.add (itemClubs); DefaultMutableTreeNode item = New DefaultMutableTreeNode ("Diamonds"); Root.add (itemDiamonds); DefaultMutableTreeNode Itemspads = New DefaultMutableTreeNode ("Spades"); Root.add (itemSpades); DefaultMutableTreeNode item increases = new DefaultMutableTreeNode ("heart"); Root.add (itemHearts); Default Trimodel Tree Model = New DefaultTreeModel (Route); Jaiti tree = new jetty (tree modal); // tree.setRootVisible (true); // tree.setShowsRootHandles (true); JPanel topPanel = new JPanel (new BorderLayout ()); TopPanel.add (new jScrollPane (tree)); Add (topPanel); }}}

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
