newFromFile
Creates a new GtkImage
displaying the file @filename.
If the file isn’t found or can’t be loaded, the resulting GtkImage
will display a “broken image” icon. This function never returns null, it always returns a valid GtkImage
widget.
If you need to detect failures to load the file, use ctor@Gdk.Texture.new_from_file to load the file yourself, then create the GtkImage
from the texture.
The storage type (see method@Gtk.Image.get_storage_type) of the returned image is not defined, it will be whatever is appropriate for displaying the file.
Return
a new GtkImage
Parameters
filename
a filename
