Detailed Description

template<typename TBaseClass, typename TDerivedClass>
class kanzi::TextBlockConceptImpl< TBaseClass, TDerivedClass >

Implementation class for TextBlockConcept.

Use the Text Block nodes to show a small amount of text in your application.

TextBlockConceptImpl derives from TextBlockConcept class, which defines the property types used by the implementation. Do not use these classes directly. To show a block of text in your application use TextBlock2D or TextBlock3D.
