A Grid extension that allows to visualize a hierarchical container. This is an experimental add-on, because I do not know what will be its value for the end-user. Right now it has minimal set of features - basically just showing the tree structure in a grid. I would like to figure out do people need it and if yes continue developing and fixing bugs. Please try it out and comment.

Known issues that are not supported:

• Sorting does not take into account the hierarchical structure. Just plain sorting.
• Hiding the column with expand button, does not create the expand button for the next first visible column.

Sample code

HierarchicalContainer hc= createContainer();

//Create grid tree container
GridTreeContainer treeContainer=new GridTreeContainer(hc);

//Second parameter in the constructor is an propertyId of the container 
// of the first visible column
GridTree gridTree= new GridTree(treeContainer,"id");

//add grid tree to layout

layout.addComponent(gridTree);
