BOOL CBCGPToolbarButton::m_bWholeText

Indicates whether a button displays full text label (TRUE), or clips the text and replace the rest by "..." if the text doesn't fit to the bounding rectangle.

If the m_bWholeText member variable is TRUE, then a button tries to display the full text label and enlarge the button if necessary. Otherwise, it doesn't change the button's size, clips the text and replaces the rest by "...".
