Sets the height to which the
PangoLayout should be ellipsized at. There
are two different behaviors, based on whether
height is positive or
[integer] the desired height of the layout in Pango units if positive, or desired number of lines if negative.
height is positive, it will be the maximum height of the layout. Only
lines would be shown that would fit, and if there is any text omitted,
an ellipsis added. At least one line is included in each paragraph regardless
of how small the height value is. A value of zero will render exactly one
line for the entire layout.
height is negative, it will be the (negative of) maximum number of lines per
paragraph. That is, the total number of lines shown may well be more than
this value if the layout contains multiple paragraphs of text.
The default value of -1 means that first line of each paragraph is ellipsized.
This behvaior may be changed in the future to act per layout instead of per
paragraph. File a bug against pango at http://bugzilla.gnome.org/ (http://bugzilla.gnome.org/) if your
code relies on this behavior.
Height setting only has effect if a positive width is set on
layout and ellipsization mode of
layout is not
The behavior is undefined if a height other than -1 is set and
ellipsization mode is set to
PANGO_ELLIPSIZE_NONE, and may change in the
