Examples
The following code example demonstrates overriding the CreateAccessibilityInstance method to create 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. Because the chart legend is not an actual Control-based control, but instead is drawn by the chart control, it does not 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 example is part of a complete code example that can be found at the AccessibleObject class overview.
protected:
// Overridden to return the custom AccessibleObject
// for the entire chart.
virtual AccessibleObject^ CreateAccessibilityInstance() override
{
return gcnew ChartControlAccessibleObject( this );
}
// Overridden to return the custom AccessibleObject
// for the entire chart.
protected override AccessibleObject CreateAccessibilityInstance()
{
return new ChartControlAccessibleObject(this);
}
' Overridden to return the custom AccessibleObject
' for the entire chart.
Protected Overrides Function CreateAccessibilityInstance() As AccessibleObject
Return New ChartControlAccessibleObject(Me)
End Function
