AccessibleObject.State Property

 

Gets the state of this accessible object.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

abstract State : AccessibleStates with get
override State : AccessibleStates with get

Property Value

Type: System.Windows.Forms.AccessibleStates

One of the AccessibleStates values, or AccessibleStates.None, if no state has been set.

Notes to Inheritors:

All objects should support this property.

The following example demonstrates the creation of an accessibility-aware chart control, using the AccessibleObject and Control.ControlAccessibleObject classes to expose accessible information. The control plots two curves along with a legend. The ChartControlAccessibleObject class, which derives from ControlAccessibleObject, is used in the CreateAccessibilityInstance method to provide custom accessible information for the chart control. Since the chart legend is not an actual Control -based control, but instead is drawn by the chart control, it does not have any built-in accessible information. Because of this, the ChartControlAccessibleObject class overrides the GetChild method to return the CurveLegendAccessibleObject that represents accessible information for each part of the legend. When an accessible-aware application uses this control, the control can provide the necessary accessible information.

This code excerpt demonstrates overriding the State property. See the AccessibleObject class overview for the complete code example.
