ConstructTextSymbol(String) Method

In This Topic

Constructs a default text symbol given its font family name. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public CIMTextSymbol ConstructTextSymbol( 
   string fontFamilyName
)

Public Overloads Function ConstructTextSymbol( _
   ByVal fontFamilyName As String _
) As CIMTextSymbol

Parameters

fontFamilyName: The font family name of the text symbol to construct.

Return Value

ArcGIS.Core.CIM.CIMTextSymbol

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method must be called within the lambda passed to QueuedTask.Run

Remarks

If the font family is null or does not exist the current default font family will be assigned. The default color, size, and font style are assigned.
