void pango_layout_set_height ( PangoLayout* layout, int height )
Sets the height to which the
PangoLayout should be ellipsized at.
There are two different behaviors, based on whether
height is positive
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 the first line of each paragraph is ellipsized.
This behavior may be changed in the future to act per layout instead of per
paragraph. File a bug against pango at
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 future.
