expanding TreeComboBox

[nicola.gioia]

when I exec a setSelectedItem(Object e) on a TreeComboBox
the combo box will always expand. It is possible to select a level in a tree in the TreeComboBox without expand the combobox?
Thanks

I wonder why I can't reproduce it in ComboBoxDemo. Are you on latest jide 1.8.5.02?

Thanks,

I have found the problem:
i need to override the method setSelectedItem(Object e) that in his body call the method this.getTree() which cause the showing of the popup
The code example needed to reproduce the problem is:

Code: Select all

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.tree.DefaultMutableTreeNode;

import com.jidesoft.combobox.TreeComboBox;

public class TreeComboExample extends JFrame{
   protected TreeComboBox tcb;
   JTree tree;
   public TreeComboExample() {
      init();
   }
   protected void init() {
      this.setContentPane(new JPanel(new BorderLayout()));
      this.setSize(new Dimension(150,60));
      this.setDefaultCloseOperation(JDialog.EXIT_ON_CLOSE);
      
      tree = new JTree();
      this.tcb = new TreeComboBox(tree.getModel());
      this.getContentPane().add(this.tcb,BorderLayout.CENTER);
      
      JButton b = new JButton("select");
      b.addActionListener(new ActionListener() {
         public void actionPerformed(ActionEvent e) {
            tcb.setSelectedItem(tree.getModel().getChild(((DefaultMutableTreeNode)tree.getModel().getRoot()).getChildAt(2),2));
            tcb.getTree();
         }});
      this.getContentPane().add(b,BorderLayout.WEST);
   }
}

In this code I have inserted the getTree() in action of button instead that in the overrided method, but the effect is the same.
my version of JIde is 1.8.5 but i don't know which build.

getTree() will show the popup. The reason is the tree is not created until popup is shown. Since you ask for the tree, we have to show popup first then return you the tree instance.
