Enum gtk4::ContentFit

source ·
#[non_exhaustive]
pub enum ContentFit { Fill, Contain, Cover, ScaleDown, }
Available on crate feature v4_8 only.
Expand description

Controls how a content should be made to fit inside an allocation.

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

Make the content fill the entire allocation, without taking its aspect ratio in consideration. The resulting content will appear as stretched if its aspect ratio is different from the allocation aspect ratio.

§

Contain

Scale the content to fit the allocation, while taking its aspect ratio in consideration. The resulting content will appear as letterboxed if its aspect ratio is different from the allocation aspect ratio.

§

Cover

Cover the entire allocation, while taking the content aspect ratio in consideration. The resulting content will appear as clipped if its aspect ratio is different from the allocation aspect ratio.

§

ScaleDown

The content is scaled down to fit the allocation, if needed, otherwise its original size is used.
