Default implementation of an ISelectionModel<(Of <(<'T>)>)> that
is based on a second collection model to hold the selected elements.
|
| DictionaryMapper<(Of <(<'K, V>)>)> |
An IDictionary<(Of <(<'TKey, TValue>)>)> based implementation of an IMapper<(Of <(<'K, V>)>)>
that can handle nullNothingnullptra null reference (Nothing in Visual Basic) and other default-value keys gracefully.

A ModelManager<(Of <(<'T>)>)> implementation that manages the
visual decoration of the focused element in a canvas.
|
| HighlightPaintManager<(Of <(<'T>)>)> |
A ModelManager<(Of <(<'T>)>)> implementation that manages the
visual decorations of highlighted elements in a canvas.
|
| InputModeController<(Of <(<'T>)>)> |
A utility class that offers various implementations of interfaces
that can be used by different IInputMode implementations.
|
| InstallerBasedModelManager<(Of <(<'T>)>)> |
An implementation of the ModelManager<(Of <(<'T>)>)> class
that automatically installs, updates and removes visual representations
of items in a ICollectionModel<(Of <(<'T>)>)>.
|
| InstallerContext |
Simple basic implementation of the IInstallerContext interface.
|
| InstallerContextExtensions |
Extension method class for IInstallerContext |
| ItemEventArgs<(Of <(<'T>)>)> |
Event argument class used by ICollectionModel<(Of <(<'T>)>)> and
similar that holds a specific item that is related to the event.
|
| ListEnumerable<(Of <(<'T>)>)> |
Wraps a simple IEnumerable<(Of <(<'T>)>)>
into a IListEnumerable<(Of <(<'T>)>)>.
|
| MapperExtensions |
Extension method holder class that extends the
IMapper<(Of <(<'K, V>)>)> type with utility methods.
|
| Mappers |
Utility class that provides convenience methods related to IMapper<(Of <(<'K, V>)>)> |
| ModelManager<(Of <(<'T>)>)> |
An abstract implementation of a utility class that manages
the visual representations of items in a CanvasControl |
| SelectionPaintManager<(Of <(<'T>)>)> |
A ModelManager<(Of <(<'T>)>)> implementation that manages the
visual decorations of selected elements in a canvas.
|
| TypeBasedItemInstaller<(Of <(<'T>)>)> |
An implementation of the IModelItemInstaller<(Of <(<'T>)>)> interface
that will use a fixed ICanvasObjectDescriptor for
each item that is assignable a specific type.
|
| WeakDictionaryMapper<(Of <(<'K, V>)>)> |
An IDictionary<(Of <(<'TKey, TValue>)>)> based implementation of an IMapper<(Of <(<'K, V>)>)>
that can handle null keys gracefully and uses weak keys.
|
Interfaces
| Interface | Description | |
|---|---|---|
 | IAddBridgesCallback | |
| ICanvasGroupProvider<(Of <(<'T>)>)> |
Simple query interface that returns an ICanvasObjectGroup
for a given item.
|
| ICollectionModel<(Of <(<'T>)>)> |
The interface for a collection that will notify registered event handlers
of changes to its contents.
|
| IInstallerContext |
The context object that is passed to IModelItemInstaller<(Of <(<'T>)>)>,
ISelectionInstaller, IHighlightInstaller, etc.
|
| IListEnumerable<(Of <(<'T>)>)> |
An extension to the IEnumerable<(Of <(<'T>)>)> interface
that allows for indexed access and retrieval of the element count.
|
| IMapper<(Of <(<'K, V>)>)> |
A simple interface for a typed dictionary-like implementation.
|
| IModelItem |
The interface used by items that belong to a model, that most
of the utility classes for the CanvasControl
can deal with.
|
| IModelItemDescriptor<(Of <(<'T>)>)> |
Simple handle interface used by ModelManager<(Of <(<'T>)>)> |
| IModelItemInstaller<(Of <(<'T>)>)> |
An interface for a class that installs visual representations of items
in a canvas control.
|
| IObstacleProvider |
The interface that is used by BridgeManager
to add obstacles
to list of obstacles that need to be taken into account during rendering.
|
| ISelectionInstaller |
An interface for objects that can install a visual representation of
a selection decoration of an item in the model displayed in a canvas.
|
| ISelectionModel<(Of <(<'T>)>)> |
An interface that models the selection state of a set of items.
|
Delegates
| Delegate | Description | |
|---|---|---|
 | ItemEventHandler<(Of <(<'T>)>)> |

Enumeration for use in conjunction with BridgeManager
and GetCrossingStyle(IRenderContext).
|
| ShowFocusPolicy |
The enumeration that describes the possible different policies for displaying the
focus of items managed by the FocusPaintManager<(Of <(<'T>)>)> |
