Constants

• Word Wrapping - wrapping occurs at word boundaries, unless the word itself doesn’t fit on a single line
• Char Wrapping - wrapping occurs before the first character that doesn’t fit
• Clipping - lines are simply not drawn past the edge of the text container
• Truncating Head - the line is displayed so that the end fits in the container and the missing text at the beginning of the line is indicated by an ellipsis glyph
• Truncating Tail - the line is displayed so that the beginning fits in the container and the missing text at the end of the line is indicated by an ellipsis glyph
• Truncating Middle - the line is displayed so that the beginning and end fit in the container and the missing text in the middle is indicated by an ellipsis glyph
