  The Smart GWT system supports hierarchical data (also referred to as tree data due to its "branching" organization) with:
  - the `Tree` class, which manipulates hierarchical data sets
  - the TreeGrid widget class, which extends the ListGrid class to visually present tree data in an expandable/collapsible format.
  - the ColumnTree widget class, which visually presents tree data in a so-called "Miller Column" format.
  For information on DataBinding Trees, see `TreeDataBinding`.

  A ColumnTree shows a single branch of the underlying `Tree` horizontally, from left to right. Thus, the leftmost column shows all the top-level nodes. When the user clicks one of those nodes, a new column is shown immediately to the right of the top-level column, showing the selected node's children. Additional columns are shown as required to present lower-level children. The behavior of ColumnTree is similar to that of the Browser interface in the Apple™ iTunes™ application.

      By default, returns `firstColumnTitle` for the first column, and for subsequent columns, the result of `this.data.getTitle()` called on the `node` passed to this function.

      Parameters:
        `node` - parent node for the nodes to be shown in the column

      If you want to suppress icons altogether, provide an override of this method that simply returns null.

      Note that the full icon URL will be derived by applying `Canvas.getImgURL()` to the value returned from this method.

      If `colNum` is passed, returns the record found in that column at that index, or null if the column doesn't exist or the index is too high.

      With no `colNum` parameter, a record's index is it's position counting from the first record of the first column and including all records in each column. Note that both index and colNum are zero-based - so the first column is column 0, not column 1.

      Parameters:
        `index` - index of record to return.
      Returns:
        node at the specified index

    - #### getRecord

                           java.lang.Integer colNum)

      Retrieve a record by index.

      If `colNum` is passed, returns the record found in that column at that index, or null if the column doesn't exist or the index is too high.

      With no `colNum` parameter, a record's index is it's position counting from the first record of the first column and including all records in each column. Note that both index and colNum are zero-based - so the first column is column 0, not column 1.

      Parameters:
        `index` - index of record to return.
        `colNum` - optional index of the column
      Returns:
        node at the specified index

    - #### getSelectedRecord

          public Record getSelectedRecord()

      Get the selected record, that is, the parent of the nodes in the rightmost visible column.

      If only the first column is showing, the root node is returned (which can be detected via `Tree.isRoot()`).

      Returns:
        the selected record

    - #### navigateBack

          public void navigateBack()

      Parameters:
        `node` - parent node for the nodes to be shown in the column
        `colNum` - index of the column

    - #### setDefaultProperties

          public static void setDefaultProperties(ColumnTree columnTreeProperties)

      Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

      Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

      Parameters:
        `columnTreeProperties` - properties that should be used as new defaults when instances of this class are created

      Note that regardless of the `dataPageSize` setting, a component will always fetch all of data that it needs to draw. Settings such as `showAllRecords`, `drawAllMaxCells` and `drawAheadRatio` can cause more rows than the configured `dataPageSize` to be fetched.

      Specified by:
        `setDataPageSize` in interface `DataBoundComponent`
      Parameters:
        `dataPageSize` - dataPageSize Default value is 75

      If true, the set of fields given by the "default binding" (see `fields`) is used, with any fields specified in `component.fields` acting as overrides that can suppress or modify the display of individual fields, without having to list the entire set of fields that should be shown.

      If `component.fields` contains fields that are not found in the DataSource, they will be shown after the most recently referred to DataSource field. If the new fields appear first, they will be shown first.

      Specified by:
        `setUseAllDataSourceFields` in interface `DataBoundComponent`
      Parameters:
        `useAllDataSourceFields` - useAllDataSourceFields Default value is false

      If true, the set of fields given by the "default binding" (see `fields`) is used, with any fields specified in `component.fields` acting as overrides that can suppress or modify the display of individual fields, without having to list the entire set of fields that should be shown.

      If `component.fields` contains fields that are not found in the DataSource, they will be shown after the most recently referred to DataSource field. If the new fields appear first, they will be shown first.

      Specified by:
        `getUseAllDataSourceFields` in interface `DataBoundComponent`
      Returns:
        Boolean

    - #### setShowHiddenFields

      Description copied from interface: `DataBoundComponent`
      Whether to show fields marked `hidden:true` when a DataBoundComponent is given a DataSource but no `component.fields`.

      The `hidden` property is used on DataSource fields to mark fields that are never of meaning to an end user.

      Specified by:
        `setShowHiddenFields` in interface `DataBoundComponent`
      Parameters:
        `showHiddenFields` - showHiddenFields Default value is false

      The `hidden` property is used on DataSource fields to mark fields that are never of meaning to an end user.

      Specified by:
        `getShowHiddenFields` in interface `DataBoundComponent`
      Returns:
        Boolean

    - #### setShowComplexFields

          public void setShowComplexFields(java.lang.Boolean showComplexFields)

      Description copied from interface: `DataBoundComponent`
      Whether to show fields of non-atomic types when a DataBoundComponent is given a DataSource but no `component.fields`.

      If true, the component will show fields that declare a complex type, for example, a field 'shippingAddress' that declares type 'Address', where 'Address' is the ID of a DataSource that declares the fields of a shipping address (city, street name, etc).

      Such fields may need custom formatters or editors in order to create a usable interface, for example, an Address field in a ListGrid might use a custom formatter to combine the relevant fields of an address into one column, and might use a pop-up dialog for editing.

      Note : This is an advanced setting

      Specified by:
        `setShowComplexFields` in interface `DataBoundComponent`
      Parameters:
        `showComplexFields` - showComplexFields Default value is true

      Parameters:
        `exportAll` - exportAll Default value is false

    - #### getExportAll

          public java.lang.Boolean getExportAll()

      Description copied from interface: `DataBoundComponent`
      Setting exportAll to true prevents the component from passing its list of fields to the export call. The result is the export of all visible fields from `fields`.

      If exportAll is false, an export operation will first consider `exportFields`, if it's set, and fall back on all visible fields from `fields` otherwise.

    - #### setPreventDuplicates

          public void setPreventDuplicates(java.lang.Boolean preventDuplicates)
                                    throws java.lang.IllegalStateException

      Description copied from interface: `DataBoundComponent`
      If set, detect and prevent duplicate records from being transferred to this component, either via drag and drop or via `DataBoundComponent.transferSelectedData(com.smartgwt.client.widgets.DataBoundComponent)`. When a duplicate transfer is detected, a dialog will appear showing the `duplicateDragMessage`.

      If the component either does not have a `DataSource` or has a DataSource with no `primaryKey` declared, duplicate checking is off by default. If duplicate checking is enabled, it looks for an existing record in the dataset that has all of the properties of the dragged record, and considers that a duplicate.

      For `DragDataAction`:"copy" where the target DataSource is related to the source DataSource by foreignKey, a duplicate means that the target list, as filtered by the current criteria, already has a record whose value for the foreignKey field matches the primaryKey of the record being transferred.

      For example, consider dragging "employees" to "teams", where "teams" has a field "teams.employeeId" which is a foreignKey pointing to "employees.id", and the target grid has search criteria causing it to show all the members of one team. A duplicate - adding an employee to the same team twice - is when the target grid's dataset contains an record with "employeeId" matching the "id" field of the dropped employee.

      Specified by:
        `setPreventDuplicates` in interface `DataBoundComponent`
      Parameters:
        `preventDuplicates` - preventDuplicates Default value is null
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created

      Description copied from interface: `DataBoundComponent`
      Message to show when a user attempts to transfer duplicate records into this component, and `preventDuplicates` is enabled. If set to null, duplicates will not be reported and the dragged duplicates will not be saved.
      Specified by:
        `setDuplicateDragMessage` in interface `DataBoundComponent`
      Parameters:
        `duplicateDragMessage` - duplicateDragMessage Default value is "Duplicates not allowed"
      Throws:

    - #### setAddDropValues

          public void setAddDropValues(java.lang.Boolean addDropValues)

      Description copied from interface: `DataBoundComponent`
      Indicates whether to add "drop values" to items dropped on this component, if both the source and target widgets are databound, either to the same DataSource or to different DataSources that are related via a foreign key. "Drop values" are properties of the dropped item that you wish to change (and persist) as a result of the item being dropped on this grid.

      If this value is true and this component is databound, `DataBoundComponent.getDropValues()` will be called for every databound item dropped on this grid, and an update performed on the item

      Specified by:
        `setAddDropValues` in interface `DataBoundComponent`
      Parameters:
        `addDropValues` - addDropValues Default value is true

    - #### getAddDropValues

          public java.lang.Boolean getAddDropValues()

      Description copied from interface: `DataBoundComponent`
      Indicates whether to add "drop values" to items dropped on this component, if both the source and target widgets are databound, either to the same DataSource or to different DataSources that are related via a foreign key. "Drop values" are properties of the dropped item that you wish to change (and persist) as a result of the item being dropped on this grid.

      If this value is true and this component is databound, `DataBoundComponent.getDropValues()` will be called for every databound item dropped on this grid, and an update performed on the item

      Specified by:
        `getAddDropValues` in interface `DataBoundComponent`
      Returns:
        Boolean

    - #### setDropValues

          public void setDropValues(java.util.Map dropValues)

      Description copied from interface: `DataBoundComponent`
      When an item is dropped on this component, and `addDropValues` is true and both the source and target widgets are databound, either to the same DataSource or to different DataSources that are related via a foreign key, this object provides the "drop values" that Smart GWT will apply to the dropped object before updating it.

      If this property is not defined, Smart GWT defaults to returning the selection criteria currently in place for this component. Thus, any databound items (for example, rows from other grids bound to the same DataSource) dropped on the grid will, by default, be subjected to an update that makes them conform to the grid's current filter criteria.

      Note : This is an advanced setting

      Specified by:
        `setDropValues` in interface `DataBoundComponent`
      Parameters:
        `dropValues` - dropValues Default value is null

    - #### getDropValues

          public java.util.Map getDropValues()

      Description copied from interface: `DataBoundComponent`
      When an item is dropped on this component, and `addDropValues` is true and both the source and target widgets are databound, either to the same DataSource or to different DataSources that are related via a foreign key, this object provides the "drop values" that Smart GWT will apply to the dropped object before updating it.

      If this property is not defined, Smart GWT defaults to returning the selection criteria currently in place for this component. Thus, any databound items (for example, rows from other grids bound to the same DataSource) dropped on the grid will, by default, be subjected to an update that makes them conform to the grid's current filter criteria.

      Note : This is an advanced setting

      Specified by:
        `getDropValues` in interface `DataBoundComponent`
      Returns:
        Returns the "drop values" to apply to a record dropped on this component prior to update. Only applicable to databound components - see `dropValues` for more details. If multiple records are being dropped, this method is called for each of them in turn.

        This method returns the following:

        - Nothing, if `addDropValues` is false
        - dropValues, if that property is set. If the component's criteria object is applicable (as explained in the next item), it is merged into dropValues, with properties in dropValues taking precedence.
        - The component's criteria object, if the most recent textMatchStyle for the component was "exact" and it is simple criteria (ie, not an AdvancedCriteria object)
        - Otherwise nothing

        You can override this method if you need more complex setting of drop values than can be provided by simply supplying a dropValues object.

    - #### setProgressiveLoading

          public void setProgressiveLoading(java.lang.Boolean progressiveLoading)

      Indicates whether or not this component will load its data `progressively`

    - #### getProgressiveLoading

          public java.lang.Boolean getProgressiveLoading()

      Indicates whether or not this component will load its data `progressively`
      Returns:
      See Also:
        `ProgressiveLoading`, `DataSource.getProgressiveLoading()`

    - #### setUseFlatFields

          public void setUseFlatFields(java.lang.Boolean useFlatFields)
                                throws java.lang.IllegalStateException

      Description copied from interface: `DataBoundComponent`
      The `useFlatFields` flag causes all simple type fields anywhere in a nested set of DataSources to be exposed as a flat list for form binding.

      `useFlatFields` is typically used with imported metadata, such as `XMLTools.loadXMLSchema(java.lang.String, com.smartgwt.client.data.XSDLoadCallback)` from a `XMLTools.loadWSDL(java.lang.String, com.smartgwt.client.data.WSDLLoadCallback)`, as a means of eliminating levels of XML nesting that aren't meaningful in a user interface, without the cumbersome and fragile process of mapping form fields to XML structures.

      For example, having called `WebService.getInputDS(java.lang.String)` to retrieve the input message schema for a web service operation whose input message looks like this:

           <FindServices>
               <searchFor>search text</searchFor>
               <Options>
                   <caseSensitive>false</caseSensitive>
               </Options>
               <IncludeInSearch>
                   <serviceName>true</serviceName>
                   <documentation>true</documentation>
                   <keywords>true</keywords>
               </IncludeInSearch>
           </FindServices>

      Setting `useFlatFields` on a `DynamicForm` that is bound to this input message schema would result in 5 `FormItem` reflecting the 5 simple type fields in the message.

      For this form, the result of `DynamicForm.getValues()` might look like:

          {
              searchFor: "search text",
              caseSensitive: false,
              serviceName: true,
              documentation : true,
              keywords : true
           }

      When contacting a `WebService`, these values can be automatically mapped to the structure of the input message for a web service operation by setting `useFlatFields` (for use with `WebService.callOperation(java.lang.String, java.util.Map, java.lang.String, com.smartgwt.client.data.WebServiceCallback)`) or by setting `useFlatFields` (for use with a `DataSource` that is `'bound to a WSDL web service'` via `wsOperation`).

      Using these two facilities in conjunction (component.useFlatFields and request.useFlatFields) allows gratuitous nesting to be consistently bypassed in both the user presentation and when providing the data for XML messages.

      You can also set `useFlatFields` to automatically enable "flattened" XML serialization (request.useFlatFields) for all DataSource requests of a particular operationType.

      Note that `useFlatFields` is not generally recommended for use with structures where multiple simple type fields exist with the same name, however if used with such a structure, the first field to use a given name wins. "first" means the first field encountered in a depth first search. "wins" means only the first field will be present as a field when data binding.

      Specified by:
        `setUseFlatFields` in interface `DataBoundComponent`
      Parameters:
        `useFlatFields` - useFlatFields Default value is null
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created

    - #### getUseFlatFields

          public java.lang.Boolean getUseFlatFields()

      Description copied from interface: `DataBoundComponent`

                   <serviceName>true</serviceName>
                   <documentation>true</documentation>
                   <keywords>true</keywords>
               </IncludeInSearch>
           </FindServices>

      This method is consulted by `ListGrid.willAcceptDrop()`.

      Returns:
        Array of `Record`s that are currently selected.

    - #### transferSelectedData

          public void transferSelectedData(DataBoundComponent source)

      Description copied from interface: `DataBoundComponent`
      Simulates a drag / drop type transfer of the selected records in some other component to this component, without requiring any user interaction. This method acts on the dropped records exactly as if they had been dropped in an actual drag / drop interaction, including any special databound behavior invoked by calling `DataBoundComponent.getDropValues()` for each dropped record.

      To transfer all data in, for example, a `ListGrid`, call grid.selection.selectAll() first.

      Note that drag/drop type transfers of records between components are asynchronous operations: Smart GWT may need to perform server turnarounds to establish whether dropped records already exist in the target component. Therefore, it is possible to issue a call to `transferSelectedData()` and/or the `drop()` method of a databound component whilst a transfer is still active. When this happens, Smart GWT adds the second and subsequent transfer requests to a queue and runs them one after the other. If you want to be notified when a transfer process has actually completed, use `addDropCompleteHandler`. See the `Dragging` documentation for an overview of list grid drag/drop data transfer.

      Specified by:
        `transferSelectedData` in interface `DataBoundComponent`
      Parameters:
        `source` - source component from which the records will be tranferred

          public java.lang.String getTitleField()

      Description copied from interface: `DataBoundComponent`
      Method to return the fieldName which represents the "title" for records in this Component.
      If this.titleField is explicitly specified it will always be used. Otherwise, default implementation will check `titleField` for databound components.
      For non databound components returns the first defined field name of `"title"`, `"name"`, or `"id"`. If we dont find any field-names that match these titles, the first field in the component will be used instead.

        fieldName the title field for this component.

    - #### setDataSource

          public void setDataSource(DataSource dataSource)

      Description copied from interface: `DataBoundComponent`
      Bind to a DataSource. Binding to a DataSource means that the component will use the DataSource to provide default data for its fields.

      When binding a previously-bound componenet to a new DataSource, if the component has any existing "fields" or has a dataset, these will be discarded by default, since it is assumed the new DataSource may represent a completely unrelated set of objects. If the old "fields" are still relevant, you may be able to refer to setDataSource(dataSource, fields) as an alternative method if the widget has an implementation of it.

      Specified by:
        `setDataSource` in interface `DataBoundComponent`
      Parameters:
        `dataSource` - DataSource to bind to. Default value is null

    - #### getDataSource

      Description copied from interface: `DataBoundComponent`
      If true, when this component is first drawn, automatically call `DataBoundComponent.fetchData()` or `DataBoundComponent.filterData()` depending on `DataBoundComponent.getAutoFetchAsFilter()` . Criteria for this fetch may be picked up from `initialCriteria` and textMatchStyle may be specified via `DataBoundComponent.getAutoFetchTextMatchStyle()`.

      NOTE: If autoFetchData is set, calling ListGrid.fetchData() before draw will cause two requests to be issued, one from the manual call to fetchData() and one from the autoFetchData setting.

    - #### fetchData

          public void fetchData()

      Description copied from interface: `DataBoundComponent`
      Retrieves data from the DataSource that matches the specified criteria.

      When `fetchData()` is first called, if data has not already been provided via `setData()`, this method will create a `ResultSet`, which will be configured based on component settings such as `fetchOperation` and `dataPageSize`, as well as the general purpose `dataProperties`. The created ResultSet will automatically send a DSRequest to retrieve data from the dataSource, and from then on will automatically manage paging through large datasets, as well as performing filtering and sorting operations inside the browser when possible - see the ResultSet docs for details.

      NOTE: do not use both `autoFetchData` and a call to `fetchData()` - this may result in two DSRequests to fetch data. Use either `autoFetchData` and `setAutoFetchCriteria()` or a manual call to fetchData() passing criteria.

      Whether a ResultSet was automatically created or provided via `setData()`, subsequent calls to fetchData() will simply call `resultSet.setCriteria()`.

      Changes to criteria may or may not result in a DSRequest to the server due to client-side filtering. You can call `willFetchData(criteria)` to determine if new criteria will result in a server fetch.

      If you need to force data to be re-fetched, you can call `invalidateCache()` and new data will automatically be fetched from the server using the current criteria and sort direction. NOTE: when using `invalidateCache()` there is no need to also call `fetchData()` and in fact this could produce unexpected results.

      This method takes an optional callback parameter (set to a `DSCallback`) to fire when the fetch completes. Note that this callback will not fire if no server fetch is performed. In this case the data is updated synchronously, so as soon as this method completes you can interact with the new data. If necessary, you can use `resultSet.willFetchData()` to determine whether or not a server fetch will occur when `fetchData()` is called with new criteria.

      In addition to the callback parameter for this method, developers can use `resultSet.addDataArrivedHandler` to be notified every time data is loaded.

      Description copied from interface: `DataBoundComponent`
      Return the underlying data of this DataBoundComponent as a `RecordList`.

      Depending on the component configuration, the actual JavaScript instance of the returned RecordList may be one of several types:

      - If the component is not bound to a `DataSource`, the instance is generally an Array of `Record`.
      - If the component is bound to a DataSource, the instance is a `ResultSet`.
      - If the component is a grouped ListGrid, the instance is a `Tree`. To access the ungrouped record list regardless of grouping status, use

            isGrouped() ? getOriginalRecordList() : getRecordList()

      - If the component is a `TreeGrid`, the instance is a ResultTree.
      The underlying type determines the structure of the returned data. An Array or ResultSet represents a list of records, but a Tree or ResultTree represents a list of open rows in the tree, including groups or other nodes which contain no records.
      Specified by:
        `getRecordList` in interface `DataBoundComponent`
