TextAttributeControl

class TextAttributeControl : public HPS::Control

The HPS::TextAttributeControl class is a smart pointer that is tied to a database object. This object gives you access to all the attributes associated with text, such as font, size, and rotation. Text characteristics such as bold, italic, and underline are also accessed through the HPS::TextAttributeControl.

Default values for the various fields of HPS::TextAttributeControl can be found here.
