Enum Align

source
#[non_exhaustive]
pub enum Align { Fill, Start, End, Center, Baseline, BaselineFill, BaselineCenter, }
Expand description

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_FILLare treated similar toGTK_ALIGN_CENTERandGTK_ALIGN_FILL`, except that it positions the widget to line up the baselines, where that is supported.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Fill

stretch to fill all space if possible, center if no meaningful way to stretch

§

Start

snap to left or top side, leaving space on right or bottom

§

End

snap to right or bottom side, leaving space on left or top

§

Center

center natural width of widget inside the allocation

§

Baseline

align the widget according to the baseline. Use GTK_ALIGN_BASELINE_FILL instead

§

BaselineFill

Available on crate feature v4_12 only.

a different name for GTK_ALIGN_BASELINE.

§

BaselineCenter

Available on crate feature v4_12 only.

stretch to fill all space, but align the baseline.
