Enum gtk4::Align

source ·
#[non_exhaustive]
pub enum Align {
    Fill,
    Start,
    End,
    Center,
    Baseline,
    // some variants omitted
}
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 property::Widget::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 Start and End are interpreted relative to text direction.

Baseline support is optional for containers and widgets, and it is only supported for vertical alignment. When it’s not supported by a child or a container it is treated as Fill.

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. See Widget.
