JTree � doesn�t show text in combination with icon correctly.

Question

I am trying to display in each node different (custom) icon (or none � according to the info read from file) + text. The icons are of different sizes (no t greater than 16 x 16 pixels). In each node from left first the icon is displayed than the text. My problem is that in some nodes not the whole text is drawn, only three dots indicate that there should be some more text. I suppose that the 'paint � or �getTreeCellRendererComponent � method does not add the icon�s width to the total node width represented by Jlabel. Maybe calling method �nodeChanged� could solve the problem, but I cannot call it from �getTreeCellRendererComponent � as it creates endless recurrency. Here is the code for the changed method:
�
public Component getTreeCellRendererComponent(JTree tree, Object value,
� ��������� boolean sel,
����������������� boolean expanded,
����������������� boolean leaf, int row,
����������������� boolean hasFocus) {
� ���
� ��� //String stringValue = tree.convertValueToText(value, sel, expanded, leaf, row, hasFocus);
� ��� String stringValue = value.toString();�
� ��� this.tree = tree;
� ��� this.hasFocus = hasFocus;
� ��� setText(stringValue);
� ��� if(sel) {
� ��������� setForeground(getTextSelectionColor());
� ��� }
� ��� else {
� ��������� setForeground(getTextNonSelectionColor());
� ��� }
�
� ��� // SET APPROPRIATE ICON FOR EACH NODE
� ��� TreePath actualNodePath = tree.getPathForRow(row);
� ��� Object actNode = null;
��� if (actualNodePath != null)
��� � actNode = actualNodePath.getLastPathComponent();
��� if (actNode != null && actNode instanceof TreeNodeGIS) {
��� � TreeNodeGIS actualnode = (TreeNodeGIS)actNode;
��� � if (actualnode.xmlNode != null) {
��� ������� setIcon(getNodeIcon(actualnode.xmlNode, defaultIconPath));
��� ������� DefaultTreeModel dtm = (DefaultTreeModel) tree.getModel();
� ��������� //((DefaultTreeModel)tree.getModel()).nodeChanged(actualnode);
��� � }
��� }
� ��� // end SET APPROPRIATE ICON FOR EACH NODE
��� setComponentOrientation(tree.getComponentOrientation());
� ��� selected = sel;
� ��� return this;
� }
�
Thank You in advance for every advice.

The problem about calling nodechanged() in the getTreeCellRendererComponent() is that if U call from within that method U get indirect recursion - it seems that calling nodechanged() fires an event that calls getTreeCellRendererComponent() and so on.. Because I tried that and the whole application seized to respond for a while and the threw some exception - i do not remember which one - but the list of problems was too long - as by endless recursion stopped just by the Virtual machine (stack overflow or smth. like that). And I do not know from where should I call that method nodechanged(), as getTreeCellRendererComponent() is called within swing somewhere.
Could someone help me?
