com.esri.arcgis.controls
Class ITOCControlDefaultProxy

java.lang.Object
  extended by com.esri.arcgis.interop.Dispatch
      extended by com.esri.arcgis.controls.ITOCControlDefaultProxy
All Implemented Interfaces:
ITOCControlDefault, Externalizable, Serializable

public class ITOCControlDefaultProxy
extends com.esri.arcgis.interop.Dispatch
implements ITOCControlDefault, Serializable

Provides access to members that control the TOCControl.

Description

The ITOCControlDefault interface is the default dispatch interface that most development environments will automatically expose. For example, placing the TOCControl in a container will typically generate an object called TOCControl1. The properties and methods available directly on this object correspond to this interface, together with container specific properties and methods.

The ITOCControlDefault interface is a 'pure' dispatch interface, so can be extended with new properties and methods at future releases of ArcGIS. The methods and properties are identical to the highest numbered main interface on the TOCControl. For example, ITOCControlDefault is equivalent to ITOCControl2, but at future releases this could become ITOCControl3. By using the ITOCControlDefault interface you are guaranteed to always have access to the latest TOCControl.

There is a small performance overhead in making calls through to a pure dispatch interface, but to avoid this you can QI to a specific interface. In some development environments it is not possible to QI directly on the control to other COM interfaces, because the control is contained within a wrapper object. Use the Object property to get the real control before performing the QI.

In most development evironments the control's property pages can be used to load either a cursor (.cur) or icon (.ico) file. A cursor contains a custom 'hotspot' location and can be any size. The 'hotspot' location for an icon file defaults to the center of the icon. This property cannot be used to load animated cursor (.ani) files.

To programatically create an object implementing IPictureDisp there is the win32 function OleLoadPicture or helper methods depending on the development environment.

A property that specifies interception of key strokes that are normally handled by the container. When intercepted the OnKeyDown and OnKeyUp events will be called. This value can be a combined bit mask of esriKeyIntercept enum values.

Description

Returns or sets keys on the keyboard that will be intercepted by the TOCControl, triggering the OnKeyDown and OnKeyUp events when pressed. These keys are often hidden from the TOCControl by the development environment container. By default the KeyIntercept is set to esriKeyInterceptNone.

Many development environment containers use the up, down, left and right arrow keys to change control focus on a form. These keys can also be useful for navigating around the display. To intercept the arrow keys and the Tab key combine the enum values using a logical OR operation (esriKeyInterceptArrowKeys OR esriKeyInterceptTabKey, which is 1 OR 4 = 5).

By default when dragging and dropping a layer between maps, a copy of the layer will be added into the map the layer is dropped into. To move the dragged layer, rather than copy it press the CTRL key while dragging and dropping.
