Enum gtk4::ImageType

#[non_exhaustive]
pub enum ImageType {
    Empty,
    IconName,
    Gicon,
    Paintable,
    // some variants omitted
}

Describes the image data representation used by a Image.

If you want to get the image from the widget, you can only get the currently-stored representation; for instance, if the Image::storage_type() returns Paintable, then you can call Image::paintable().

For empty images, you can request any storage type (call any of the “get” functions), but they will all return None values.

Variants (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.

Empty

there is no image displayed by the widget

IconName

the widget contains a named icon

Gicon

the widget contains a GIcon

Paintable

the widget contains a gdk::Paintable
