Class Details

class Atk.Image
Bases:GObject.GInterface
Structure:Atk.ImageIface

Atk.Image should be implemented by Atk.Object subtypes on behalf of components which display image/pixmap information onscreen, and which provide information (other than just widget borders, etc.) via that image content. For instance, icons, buttons with icons, toolbar elements, and image viewing panes typically should implement Atk.Image.

Atk.Image primarily provides two types of information: coordinate information (useful for screen review mode of screenreaders, and for use by onscreen magnifiers), and descriptive information. The descriptive information is provided for alternative, text-only presentation of the most significant information present in the image.

get_image_description()[source]
Returns:a string representing the image description
Return type:str

Get a textual description of this image.

get_image_locale()[source]
Returns:a string corresponding to the POSIX LC_MESSAGES locale used by the image description, or None if the image does not specify a locale.
Return type:str or None

New in version 1.12.

get_image_position(coord_type)[source]
Parameters:coord_type (Atk.CoordType) – specifies whether the coordinates are relative to the screen or to the components top level window
Returns:
x:address of int to put x coordinate position; otherwise, -1 if value cannot be obtained.
y:address of int to put y coordinate position; otherwise, -1 if value cannot be obtained.
Return type:(x: int, y: int)

Gets the position of the image in the form of a point specifying the images top-left corner.

get_image_size()[source]
Returns:
width:filled with the image width, or -1 if the value cannot be obtained.
height:filled with the image height, or -1 if the value cannot be obtained.
Return type:(width: int, height: int)

Get the width and height in pixels for the specified image. The values of width and height are returned as -1 if the values cannot be obtained (for instance, if the object is not onscreen).

set_image_description(description)[source]
Parameters:description (str) – a string description to set for self
Returns:boolean True, or False if operation could not be completed.
Return type:bool

Sets the textual description for this image.

do_get_image_description() virtual
Returns:a string representing the image description
Return type:str

Get a textual description of this image.

do_get_image_locale() virtual
Returns:a string corresponding to the POSIX LC_MESSAGES locale used by the image description, or None if the image does not specify a locale.
Return type:str or None

New in version 1.12.

do_get_image_position(coord_type) virtual
Parameters:coord_type (Atk.CoordType) – specifies whether the coordinates are relative to the screen or to the components top level window
Returns:
x:address of int to put x coordinate position; otherwise, -1 if value cannot be obtained.
y:address of int to put y coordinate position; otherwise, -1 if value cannot be obtained.
Return type:(x: int, y: int)

Gets the position of the image in the form of a point specifying the images top-left corner.

do_get_image_size() virtual
Returns:
width:filled with the image width, or -1 if the value cannot be obtained.
height:filled with the image height, or -1 if the value cannot be obtained.
Return type:(width: int, height: int)

Get the width and height in pixels for the specified image. The values of width and height are returned as -1 if the values cannot be obtained (for instance, if the object is not onscreen).

do_set_image_description(description) virtual
Parameters:description (str) – a string description to set for image
Returns:boolean True, or False if operation could not be completed.
Return type:bool

Sets the textual description for this image.
