Trait containing all Image methods.

Implementors

Image

Required methods

fn clear(&self)

Resets the image to be empty.

fn get_animation(&self) -> Option<PixbufAnimation>

Gets the gdk_pixbuf::PixbufAnimation being displayed by the Image. The storage type of the image must be ImageType::Empty or ImageType::Animation (see ImageExt::get_storage_type). The caller of this function does not own a reference to the returned animation.

Returns

the displayed animation, or None if the image is empty

fn get_gicon(&self) -> (Icon, IconSize)

Gets the gio::Icon and size being displayed by the Image. The storage type of the image must be ImageType::Empty or ImageType::Gicon (see ImageExt::get_storage_type). The caller of this function does not own a reference to the returned gio::Icon.

gicon

place to store a gio::Icon, or None

size

place to store an icon size (IconSize), or None

fn get_pixbuf(&self) -> Option<Pixbuf>

Gets the gdk_pixbuf::Pixbuf being displayed by the Image. The storage type of the image must be ImageType::Empty or ImageType::Pixbuf (see ImageExt::get_storage_type). The caller of this function does not own a reference to the returned pixbuf.

Returns

the displayed pixbuf, or None if the image is empty

fn get_pixel_size(&self) -> i32

Gets the pixel size used for named icons.

Returns

the pixel size used for named icons.

fn get_storage_type(&self) -> ImageType

Gets the type of representation being used by the Image to store image data. If the Image has no image data, the return value will be ImageType::Empty.

Returns

image representation being used

fn set_from_animation<P: IsA<PixbufAnimation>>(&self, animation: &P)

Causes the Image to display the given animation (or display nothing, if you set the animation to None).

animation

the gdk_pixbuf::PixbufAnimation

fn set_from_file<P: AsRef<Path>>(&self, filename: P)

See Image::new_from_file for details.

filename

a filename or None

fn set_from_gicon<P: IsA<Icon>>(&self, icon: &P, size: IconSize)

See Image::new_from_gicon for details.

icon

an icon

size

an icon size (IconSize)

fn set_from_icon_name(&self, icon_name: Option<&str>, size: IconSize)

See Image::new_from_icon_name for details.

icon_name

an icon name or None

size

an icon size (IconSize)

fn set_from_pixbuf(&self, pixbuf: Option<&Pixbuf>)

See Image::new_from_pixbuf for details.

pixbuf

a gdk_pixbuf::Pixbuf or None

fn set_from_resource(&self, resource_path: Option<&str>)

See Image::new_from_resource for details.

resource_path

a resource path or None

fn set_from_surface(&self, surface: Option<&Surface>)

See Image::new_from_surface for details.

surface

a cairo_surface_t or None

fn set_pixel_size(&self, pixel_size: i32)

Sets the pixel size to use for named icons. If the pixel size is set to a value != -1, it is used instead of the icon size set by ImageExt::set_from_icon_name.

pixel_size

the new pixel size

fn get_property_file(&self) -> Option<GString>

fn set_property_file(&self, file: Option<&str>)

fn set_property_gicon<P: IsA<Icon> + SetValueOptional>(&self, gicon: Option<&P>)

The GIcon displayed in the Image. For themed icons, If the icon theme is changed, the image will be updated automatically.

fn get_property_icon_name(&self) -> Option<GString>

The name of the icon in the icon theme. If the icon theme is changed, the image will be updated automatically.

fn set_property_icon_name(&self, icon_name: Option<&str>)

The name of the icon in the icon theme. If the icon theme is changed, the image will be updated automatically.

fn get_property_icon_size(&self) -> i32

fn set_property_icon_size(&self, icon_size: i32)

fn set_property_pixbuf(&self, pixbuf: Option<&Pixbuf>)

fn get_property_pixbuf_animation(&self) -> Option<PixbufAnimation>

fn set_property_pixbuf_animation<P: IsA<PixbufAnimation> + SetValueOptional>(
    &self,
    pixbuf_animation: Option<&P>
)

fn get_property_resource(&self) -> Option<GString>

A path to a resource file to display.

fn set_property_resource(&self, resource: Option<&str>)

A path to a resource file to display.

fn get_property_surface(&self) -> Option<Surface>

fn set_property_surface(&self, surface: Option<&Surface>)

fn get_property_use_fallback(&self) -> bool

Whether the icon displayed in the Image will use standard icon names fallback. The value of this property is only relevant for images of type ImageType::IconName and ImageType::Gicon.

fn set_property_use_fallback(&self, use_fallback: bool)

Whether the icon displayed in the Image will use standard icon names fallback. The value of this property is only relevant for images of type ImageType::IconName and ImageType::Gicon.
