Required Methods
sourcefn animation(&self) -> Option<PixbufAnimation>
fn 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 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
sourcefn gicon(&self) -> (Icon, IconSize)
fn 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 storage_type()
).
The caller of this function does not own a reference to the
returned gio::Icon
.
Returns
gicon
place to store a
gio::Icon
, or None
size
sourcefn pixbuf(&self) -> Option<Pixbuf>
fn 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 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
sourcefn pixel_size(&self) -> i32
fn pixel_size(&self) -> i32
sourcefn storage_type(&self) -> ImageType
fn 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
sourcefn set_from_animation(&self, animation: &impl IsA<PixbufAnimation>)
fn set_from_animation(&self, animation: &impl IsA<PixbufAnimation>)
sourcefn set_from_file(&self, filename: Option<impl AsRef<Path>>)
fn set_from_file(&self, filename: Option<impl AsRef<Path>>)
sourcefn set_from_gicon(&self, icon: &impl IsA<Icon>, size: IconSize)
fn set_from_gicon(&self, icon: &impl IsA<Icon>, size: IconSize)
sourcefn set_from_icon_name(&self, icon_name: Option<&str>, size: IconSize)
fn set_from_icon_name(&self, icon_name: Option<&str>, size: IconSize)
See Image::from_icon_name()
for details.
icon_name
an icon name or None
size
an icon size (IconSize
)
sourcefn set_from_pixbuf(&self, pixbuf: Option<&Pixbuf>)
fn set_from_pixbuf(&self, pixbuf: Option<&Pixbuf>)
sourcefn set_from_resource(&self, resource_path: Option<&str>)
fn set_from_resource(&self, resource_path: Option<&str>)
sourcefn set_from_surface(&self, surface: Option<&Surface>)
fn set_from_surface(&self, surface: Option<&Surface>)
sourcefn set_pixel_size(&self, pixel_size: i32)
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
set_from_icon_name()
.
pixel_size
the new pixel size
fn file(&self) -> Option<GString>
fn set_file(&self, file: Option<&str>)
sourcefn set_gicon<P: IsA<Icon>>(&self, gicon: Option<&P>)
fn set_gicon<P: IsA<Icon>>(&self, gicon: Option<&P>)
The GIcon displayed in the GtkImage. For themed icons, If the icon theme is changed, the image will be updated automatically.
sourcefn icon_name(&self) -> Option<GString>
fn 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.
sourcefn set_icon_name(&self, icon_name: Option<&str>)
fn set_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 set_pixbuf(&self, pixbuf: Option<&Pixbuf>)
fn pixbuf_animation(&self) -> Option<PixbufAnimation>
fn set_pixbuf_animation<P: IsA<PixbufAnimation>>(
&self,
pixbuf_animation: Option<&P>
)
sourcefn set_resource(&self, resource: Option<&str>)
fn set_resource(&self, resource: Option<&str>)
A path to a resource file to display.
fn surface(&self) -> Option<Surface>
fn set_surface(&self, surface: Option<&Surface>)
sourcefn uses_fallback(&self) -> bool
fn uses_fallback(&self) -> bool
Whether the icon displayed in the GtkImage will use
standard icon names fallback. The value of this property
is only relevant for images of type ImageType::IconName
and ImageType::Gicon
.
sourcefn set_use_fallback(&self, use_fallback: bool)
fn set_use_fallback(&self, use_fallback: bool)
Whether the icon displayed in the GtkImage will use
standard icon names fallback. The value of this property
is only relevant for images of type ImageType::IconName
and ImageType::Gicon
.
