      Creates a new TreeGrid with an initial set of columns for each of the bean's properties. The property-values of the bean will be converted to Strings. Full names of the properties will be used as the column keys and the property captions will be used as the column headers.

      When autoCreateColumns is true, only the direct properties of the bean are included, and they will be in alphabetical order. Use Grid.setColumns(String...) to define which properties to include and in which order. You can also add a column for an individual property with Grid.addColumn(String). Both of these methods support also sub-properties with dot-notation, e.g. "property.nestedProperty".

      Parameters:

      beanType - the bean type to use, not null

      autoCreateColumns - when true, columns are created automatically for the properties of the beanType
