getSelectedItem

public Object getSelectedItem()
                       throws IOException,
                              AutomationException
The selected item (could be an enumerator).

Description

This property is not functional for TOCSelectionView. When working with a TOCDisplayView or TOCCatalogView this property has several usages:

1. The property can be a single object of any of the following types:

IMap
ILayer
ILegendGroup
IWorkspace (source view only)
IDataset (source view only)
IStandaloneTable (source view only)

2. The property can be a Set of items of the types listed in 1. Only multiple items of the same type can be selected simultaneously, so when setting this property using a Set, the Set should contain items of the same type.

3. The property can be an array where the contents of the array represent the hierarchical path to a single selected item. This is common when a single legend class is selected.

For example: If Array(0) = pMap, Array(1) = pLayer, Array(2) = pLegendGroup, and Array(3) = n, then the selected item is the nth legend class in pLegendGroup. When setting or adding to the selection, pass higher-level objects (in this case the IMap and ILayer objects) to improve peformance.

4. The property can be an array which contains an array of the structure explained in 3. This is common when multiple legend classes are selected.

                     throws IOException,
                            AutomationException

addToSelectedItems

public void addToSelectedItems(Object item)
                        throws IOException,
                               AutomationException
Adds to the selected items.

Description

This method is not functional for TOCSelectionView. When working with a TOCDisplayView or TOCCatalogView the item parameter has several usages:

1. The parameter can be a single object of any of the following types:

IMap
ILayer
ILegendGroup
IWorkspace (source view only)
IDataset (source view only)
IStandaloneTable (source view only)

2. The parameter can be a Set of items of the types listed in 1. Only multiple items of the same type can be selected simultaneously, so the Set should contain items of the same type.

3. The parameter can be an array where the contents of the array represent the hierarchical path to a single selected item. Use this to add a single legend class to the selection.

For example: If Array(0) = pMap, Array(1) = pLayer, Array(2) = pLegendGroup, and Array(3) = n, then the method will add the nth legend class in pLegendGroup. When building the array, include higher-level objects (in this case the IMap and ILayer objects) to improve peformance.

4. The parameter can be an array which contains an array of the structure explained in 3. Use this to add multiple legend classes to the selection.

removeFromSelectedItems

public void removeFromSelectedItems(Object item)
                             throws IOException,
                                    AutomationException
Removes an item from the selected items.

Description

This method is not functional for TOCSelectionView. When working with a TOCDisplayView or TOCCatalogView the item parameter has several usages:

1. The parameter can be a single object of any of the following types:

IMap
ILayer
ILegendGroup
IWorkspace (source view only)
IDataset (source view only)
IStandaloneTable (source view only)

2. The parameter can be a Set of items of the types listed in 1. Only multiple items of the same type can be selected simultaneously, so the Set should contain items of the same type.

3. The parameter can be an array where the contents of the array represent the hierarchical path to a single selected item. Use this to remove a single legend class from the selection.

Specified by:
removeFromSelectedItems in interface IContentsView
Parameters:
item - A Variant (in)
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

getContextItem

public Object getContextItem()
                      throws IOException,
                             AutomationException
The context item (could be an enumerator).

Remarks

You need at least to write a minimalistic implementation of this property as shown here:

Private m_ContextItem as Variant

Private Property Let IContentsView_ContextItem(ByVal RHS As Variant)
m_ContextItem = RHS
End Property

Private Property Get IContentsView_ContextItem() As Variant
IContentsView_ContextItem = m_ContextItem
End Property

The ContextItem property will contain the item on which the user makes a right-click in the TOC and at this point a context menu may be shown.

At 9.0 a default context menu is shown when the user right-clicks in your custom TOC. If you need to get rid of this menu in order to implement your own you will find the Selectable Layers Tab example valuable.
