Align

class Align

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

Alignment only matters if the widget receives a “too large” allocation, for example if you packed the widget with the hexpand property inside a Box, then the widget might get extra space. If you have for example a 16x16 icon inside a 32x32 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 GTK_ALIGN_START and GTK_ALIGN_END are interpreted relative to text direction.

Baseline support is optional for containers and widgets, and is only available for vertical alignment. GTK_ALIGN_BASELINE_CENTER and ``GTK_ALIGN_BASELINE_FILL` are treated similar to GTK_ALIGN_CENTER and GTK_ALIGN_FILL, except that it positions the widget to line up the baselines, where that is supported.
