pangoLayoutSetHeight {RGtk2} | R Documentation

## pangoLayoutSetHeight

### Description

Sets the height to which the `PangoLayout` should be ellipsized at. There are two different behaviors, based on whether `height` is positive or negative.

### Usage

    pangoLayoutSetHeight(object, height)

### Arguments

``object`` | [`PangoLayout`] a `PangoLayout`.
``height`` | [integer] the desired height of the layout in Pango units if positive, or desired number of lines if negative.

### Details

If `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.

If `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 `PANGO_ELLIPSIZE_NONE`. 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. Since 1.20
