get-descent

Returns the font descent for the buffer. This method is primarily used when a buffer is an item within another buffer.

The result is only valid when the buffer is viewed (see Basic Organization). For wx:media-edit% objects, calling this method may force the recalculation of location information if a maximum width is set for the buffer, even if the buffer currently has delayed refreshing (see refresh-delayed?).
