is_link property

Returns True if the OLE object is linked (when OleFormat.source_full_name is specified).

@property
def is_link(self) -> bool:
    ...

Examples

Shows how to insert linked and unlinked OLE objects.

doc = aw.Document()
builder = aw.DocumentBuilder(doc)
# Embed a Microsoft Visio drawing into the document as an OLE object.
builder.insert_ole_object(IMAGE_DIR + 'Microsoft Visio drawing.vsd', 'Package', False, False, None)
# Insert a link to the file in the local file system and display it as an icon.
builder.insert_ole_object(IMAGE_DIR + 'Microsoft Visio drawing.vsd', 'Package', True, True, None)
# Inserting OLE objects creates shapes that store these objects.
shapes = [node.as_shape() for node in doc.get_child_nodes(aw.NodeType.SHAPE, True)]
self.assertEqual(2, len(shapes))
self.assertEqual(2, len([shape for shape in shapes if shape.shape_type == aw.drawing.ShapeType.OLE_OBJECT]))
# If a shape contains an OLE object, it will have a valid "ole_format" property,
# which we can use to verify some aspects of the shape.
ole_format = shapes[0].ole_format
self.assertEqual(False, ole_format.is_link)
self.assertEqual(False, ole_format.ole_icon)
ole_format = shapes[1].ole_format
self.assertEqual(True, ole_format.is_link)
self.assertEqual(True, ole_format.ole_icon)
self.assertTrue(ole_format.source_full_name.endswith('Images/Microsoft Visio drawing.vsd'))
self.assertEqual('', ole_format.source_item)
self.assertEqual('Microsoft Visio drawing.vsd', ole_format.icon_caption)
doc.save(ARTIFACTS_DIR + 'Shape.ole_links.docx')
# If the object contains OLE data, we can access it using a stream.
stream = ole_format.get_ole_entry('\x01CompObj')
stream.seek(0)
ole_entry_bytes = stream.read()
self.assertEqual(76, len(ole_entry_bytes))
