How create a TreeTable in DebugSession

I'm looking for a way to create a TreeTable in intellij Plugin.
The Tab in the DebugSession can I create in com.intellij.xdebugger.XDebugProcess#createTabLayouter, but I cant' create a TreeTable inside that JPanel.

My View looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<form xmlns="http://www.intellij.com/uidesigner/form/" version="1" bind-to-class="debugger.ui.RegisterViewSessionTab">
<grid id="27dc6" binding="content" layout-manager="GridLayoutManager" row-count="1" column-count="1" same-size-horizontally="false" same-size-vertically="false" hgap="-1" vgap="-1">
<margin top="0" left="0" bottom="0" right="0"/>
<constraints>
<xy x="20" y="20" width="500" height="400"/>
</constraints>
<properties/>
<border type="none"/>
<children>
<scrollpane id="86eac">
<constraints>
<grid row="0" column="0" row-span="1" col-span="1" vsize-policy="7" hsize-policy="7" anchor="0" fill="3" indent="0" use-parent-layout="false"/>
</constraints>
<properties/>
<border type="none"/>
<children>
<component id="8217" class="com.intellij.ui.treeStructure.treetable.TreeTable" binding="tree" custom-create="true">
<constraints/>
<properties/>
</component>
</children>
</scrollpane>
</children>
</grid>
</form>


And the code behinde (RegisterViewSessionTab):

pc = new DefaultRegisterNode();
sp = new DefaultRegisterNode();
DefaultRegisterNode group = new DefaultRegisterNode();

group.setName("Core Registers");
group.setDescription("Core Registers");
group.setValue("");
DefaultMutableTreeNode root = new DefaultMutableTreeNode(group);

pc.setName("PC");
pc.setDescription("Program Counter [Core]");
pc.setValue("---");
DefaultMutableTreeNode nodePc = new DefaultMutableTreeNode(pc);
root.add(nodePc);

sp.setName("SP");
sp.setDescription("Stack Pointer [Core]");
sp.setValue("---");

DefaultMutableTreeNode node = new DefaultMutableTreeNode(sp);
root.add(node);

ColumnInfo[] columnInfos = new ColumnInfo[3];
columnInfos[0] = new ColumnInfo<DefaultMutableTreeNode, String>("Name") {
@Nullable
@Override
public String valueOf(DefaultMutableTreeNode defaultRegisterNode) {
return ((DefaultRegisterNode)defaultRegisterNode.getUserObject()).getName();
}
};
columnInfos[1] = new TableModelEditor.EditableColumnInfo<DefaultMutableTreeNode, String>("Value") {
@Nullable
@Override
public String valueOf(DefaultMutableTreeNode defaultRegisterNode) {
return ((DefaultRegisterNode)defaultRegisterNode.getUserObject()).getValue();
}

@Nullable
@Override
public TableCellEditor getEditor(DefaultMutableTreeNode defaultRegisterNode) {
return new StringTableCellEditor(project);
}

@Override
public void setValue(DefaultMutableTreeNode defaultRegisterNode, String value) {
((DefaultRegisterNode)defaultRegisterNode.getUserObject()).setValue(value);
}
};
columnInfos[2] = new ColumnInfo<DefaultMutableTreeNode, String>("Description") {
@Nullable
@Override
public String valueOf(DefaultMutableTreeNode defaultRegisterNode) {
return ((DefaultRegisterNode)defaultRegisterNode.getUserObject()).getDescription();
}
};

ListTreeTableModelOnColumns registersModel = new ListTreeTableModelOnColumns(root, columnInfos);
tree = new TreeTable(registersModel);


Model class:

public class DefaultRegisterNode {
private String name;
private String description;
private String value;

public void setName(String name) {
this.name = name;
}

public String getName() {
return name;
}

public String getDescription() {
return null;
}

public void setDescription(String description) {
this.description = description;
}

public String getValue() {
return value;
}

public void setValue(String value) {
this.value = value;
}
}

But there isn't a collapsed/expanded button? How can I enable this feature in the TreeTable?

If you need something more, please contact me!
Thanks

Answer

With a TreeTableView the root node will show also. But the error isn't there. I found it.

ColumnInfo[] columnInfos = new ColumnInfo[] {
    new TreeColumnInfo("Name"),   // <-- This is important!
    new ColumnInfo<Node, String>("Name S1") {
       ...
    }
};

Add a TreeColumnInfo to the ColumnInfos above. This will add the Expand/Collapse Arrows. Now you must create a TreeCellRenderer and set to the Tree.

public static class Tree extends TreeTableView {

    public Tree(ListTreeTableModelOnColumns treeTableModel) {
        super(treeTableModel);

        setTreeCellRenderer(new Renderer());
    }

    class Renderer extends ColoredTreeCellRenderer  {
        @Override
        public void customizeCellRenderer(@NotNull JTree tree, Object value, boolean selected, boolean expanded, boolean leaf, int row, boolean hasFocus) {
            Node node = (Node)value;
            NodeModel model = node.getUserObject();

            append(model.Name);
        }

    }
}
