GEnum gtk-align

Details

Controls how a widget deals with extra space in a single x or y dimension.

Alignment only matters if the widget receives a "too large" allocation, for example if you packed the widget with the expand flag inside a gtk-box widget, then the widget might get extra space. If you have for example a 16 x 16 icon inside a 32 x 32 space, the icon could be scaled and stretched, it could be centered, or it could be positioned to one side of the space.

Note that in horizontal context the :start and :end values are interpreted relative to text direction.

The :baseline support is optional for containers and widgets, and it is only supported for vertical alignment. When it is not supported by a child widget or a container it is treated as the :fill value.
