FontTypeConverter.CanConvertFrom(ITypeDescriptorContext, Type) Method

Definition

Returns a value that indicates whether this converter can convert an instance of a specified type to a GlyphRun.

public:
 override bool CanConvertFrom(System::ComponentModel::ITypeDescriptorContext ^ context, Type ^ sourceType);
public override bool CanConvertFrom (System.ComponentModel.ITypeDescriptorContext context, Type sourceType);
override this.CanConvertFrom : System.ComponentModel.ITypeDescriptorContext * Type -> bool
Public Overrides Function CanConvertFrom (context As ITypeDescriptorContext, sourceType As Type) As Boolean

Parameters

context
ITypeDescriptorContext

An object that provides contextual information.

sourceType
Type

The type of object to convert.

Returns

true if objects of the specified type can be converted; otherwise, false.

Remarks

As implemented in this class, this method returns true only if sourceType is Uri.

The context parameter is not used. See Notes for Inheritors.

Notes to Inheritors

Override this method to provide your own conversion requirements. Use the context parameter to extract additional information about the environment from which this converter is invoked. This parameter can be null; therefore, always check it. Also, properties on the context object can return a null reference (Nothing).
