pub struct Image { /* private fields */ }
Expand description
The Image
widget displays an image.
Various kinds of object can be displayed as an image; most typically,
you would load a gdk::Texture
from a file, using the convenience function
from_file()
, for instance:
⚠️ The following code is in c ⚠️
GtkWidget *image = gtk_image_new_from_file ("myfile.png");
If the file isn’t loaded successfully, the image will contain a “broken image” icon similar to that used in many web browsers.
If you want to handle errors in loading the file yourself,
for example by displaying an error message, then load the image with
gdk::Texture::from_file()
, then create the Image
with
from_paintable()
.
Sometimes an application will want to avoid depending on external data
files, such as image files. See the documentation of GResource
inside
GIO, for details. In this case, resource
,
from_resource()
, and set_resource()
should be used.
Image
displays its image as an icon, with a size that is determined
by the application. See Picture
if you want to show an image
at is actual size.
§CSS nodes
Image
has a single CSS node with the name image
. The style classes
.normal-icons
or .large-icons
may appear, depending on the
icon-size
property.
§Accessibility
Image
uses the GTK_ACCESSIBLE_ROLE_IMG
role.

Implementations§
Source§impl Image
impl Image
Sourcepub fn from_file(filename: impl AsRef<Path>) -> Image
pub fn from_file(filename: impl AsRef<Path>) -> Image
Creates a new Image
displaying the file @filename.
If the file isn’t found or can’t be loaded, the resulting Image
will display a “broken image” icon. This function never returns None
,
it always returns a valid Image
widget.
If you need to detect failures to load the file, use
gdk::Texture::from_file()
to load the file yourself,
then create the Image
from the texture.
The storage type (see storage_type()
)
of the returned image is not defined, it will be whatever
is appropriate for displaying the file.
§filename
a filename
§Returns
a new Image
Sourcepub fn from_gicon(icon: &impl IsA<Icon>) -> Image
pub fn from_gicon(icon: &impl IsA<Icon>) -> Image
Sourcepub fn from_icon_name(icon_name: &str) -> Image
pub fn from_icon_name(icon_name: &str) -> Image
Sourcepub fn from_paintable(paintable: Option<&impl IsA<Paintable>>) -> Image
pub fn from_paintable(paintable: Option<&impl IsA<Paintable>>) -> Image
Creates a new Image
displaying @paintable.
The Image
does not assume a reference to the paintable; you still
need to unref it if you own references. Image
will add its own
reference rather than adopting yours.
The Image
will track changes to the @paintable and update
its size and contents in response to it.
§paintable
§Returns
a new Image
Sourcepub fn from_pixbuf(pixbuf: Option<&Pixbuf>) -> Image
👎Deprecated: Since 4.12
pub fn from_pixbuf(pixbuf: Option<&Pixbuf>) -> Image
Creates a new Image
displaying @pixbuf.
The Image
does not assume a reference to the pixbuf; you still
need to unref it if you own references. Image
will add its own
reference rather than adopting yours.
This is a helper for from_paintable()
, and you can’t
get back the exact pixbuf once this is called, only a texture.
Note that this function just creates an Image
from the pixbuf.
The Image
created will not react to state changes. Should you
want that, you should use from_icon_name()
.
§Deprecated since 4.12
Use from_paintable()
and
gdk::Texture::for_pixbuf()
instead
§pixbuf
§Returns
a new Image
Sourcepub fn from_resource(resource_path: &str) -> Image
pub fn from_resource(resource_path: &str) -> Image
Creates a new Image
displaying the resource file @resource_path.
If the file isn’t found or can’t be loaded, the resulting Image
will
display a “broken image” icon. This function never returns None
,
it always returns a valid Image
widget.
If you need to detect failures to load the file, use
gdk_pixbuf::Pixbuf::from_file()
to load the file yourself,
then create the Image
from the pixbuf.
The storage type (see storage_type()
) of
the returned image is not defined, it will be whatever is
appropriate for displaying the file.
§resource_path
a resource path
§Returns
a new Image
Sourcepub fn builder() -> ImageBuilder
pub fn builder() -> ImageBuilder
Creates a new builder-pattern struct instance to construct Image
objects.
This method returns an instance of ImageBuilder
which can be used to create Image
objects.
Sourcepub fn gicon(&self) -> Option<Icon>
pub fn gicon(&self) -> Option<Icon>
Gets the GIcon
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 GIcon
.
§Returns
a GIcon
Sourcepub fn icon_name(&self) -> Option<GString>
pub fn icon_name(&self) -> Option<GString>
Gets the icon name and size being displayed by the Image
.
The storage type of the image must be ImageType::Empty
or
ImageType::IconName
(see storage_type()
).
The returned string is owned by the Image
and should not
be freed.
§Returns
the icon name
Sourcepub fn paintable(&self) -> Option<Paintable>
pub fn paintable(&self) -> Option<Paintable>
Gets the image gdk::Paintable
being displayed by the Image
.
The storage type of the image must be ImageType::Empty
or
ImageType::Paintable
(see storage_type()
).
The caller of this function does not own a reference to the
returned paintable.
§Returns
the displayed paintable
Sourcepub fn pixel_size(&self) -> i32
pub fn pixel_size(&self) -> i32
Sourcepub fn storage_type(&self) -> ImageType
pub 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
Sourcepub fn set_from_file(&self, filename: Option<impl AsRef<Path>>)
pub fn set_from_file(&self, filename: Option<impl AsRef<Path>>)
Sourcepub fn set_from_gicon(&self, icon: &impl IsA<Icon>)

pub fn set_paintable(&self, paintable: Option<&impl IsA<Paintable>>)
Sourcepub fn set_from_pixbuf(&self, pixbuf: Option<&Pixbuf>)
👎Deprecated: Since 4.12
pub fn set_from_pixbuf(&self, pixbuf: Option<&Pixbuf>)
Sets a Image
to show a gdk_pixbuf::Pixbuf
.
See from_pixbuf()
for details.
Note: This is a helper for set_paintable()
,
and you can’t get back the exact pixbuf once this is called,
only a paintable.
§Deprecated since 4.12
Use set_paintable()
instead
§pixbuf
a gdk_pixbuf::Pixbuf
or NULL

of the icon size set by set_icon_name()
.
