Run class
Run class
Represents a run of characters with the same font formatting. To learn more, visit the Programming with Documents documentation article.
Remarks
All text of the document is stored in runs of text.
Run can only be a child of Paragraph or inline StructuredDocumentTag.
Inheritance: Run → Inline → Node

Examples
Shows how to format a run of text using its font property.
doc = aw.Document()
run = aw.Run(doc=doc, text='Hello world!')
font = run.font
font.name = 'Courier New'
font.size = 36
font.highlight_color = aspose.pydrawing.Color.yellow
doc.first_section.body.first_paragraph.append_child(run)
doc.save(file_name=ARTIFACTS_DIR + 'Font.CreateFormattedRun.docx')
Shows how to add, update and delete child nodes in a CompositeNode’s collection of children.
doc = aw.Document()
# An empty document, by default, has one paragraph.
self.assertEqual(1, doc.first_section.body.paragraphs.count)
# Composite nodes such as our paragraph can contain other composite and inline nodes as children.
paragraph = doc.first_section.body.first_paragraph
paragraph_text = aw.Run(doc=doc, text='Initial text. ')
paragraph.append_child(paragraph_text)
# Create three more run nodes.
run1 = aw.Run(doc=doc, text='Run 1. ')
run2 = aw.Run(doc=doc, text='Run 2. ')
run3 = aw.Run(doc=doc, text='Run 3. ')
# The document body will not display these runs until we insert them into a composite node
# that itself is a part of the document's node tree, as we did with the first run.
# We can determine where the text contents of nodes that we insert
# appears in the document by specifying an insertion location relative to another node in the paragraph.
self.assertEqual('Initial text.', paragraph.get_text().strip())
# Insert the second run into the paragraph in front of the initial run.
paragraph.insert_before(run2, paragraph_text)
self.assertEqual('Run 2. Initial text.', paragraph.get_text().strip())
# Insert the third run after the initial run.
paragraph.insert_after(run3, paragraph_text)
self.assertEqual('Run 2. Initial text. Run 3.', paragraph.get_text().strip())
# Insert the first run to the start of the paragraph's child nodes collection.
paragraph.prepend_child(run1)
self.assertEqual('Run 1. Run 2. Initial text. Run 3.', paragraph.get_text().strip())
self.assertEqual(4, paragraph.get_child_nodes(aw.NodeType.ANY, True).count)
# We can modify the contents of the run by editing and deleting existing child nodes.
paragraph.get_child_nodes(aw.NodeType.RUN, True)[1].as_run().text = 'Updated run 2. '
paragraph.get_child_nodes(aw.NodeType.RUN, True).remove(paragraph_text)
self.assertEqual('Run 1. Updated run 2. Run 3.', paragraph.get_text().strip())
self.assertEqual(3, paragraph.get_child_nodes(aw.NodeType.ANY, True).count)
Shows how to construct an Aspose.Words document by hand.
doc = aw.Document()
# A blank document contains one section, one body and one paragraph.
# Call the "RemoveAllChildren" method to remove all those nodes,
# and end up with a document node with no children.
doc.remove_all_children()
# This document now has no composite child nodes that we can add content to.
# If we wish to edit it, we will need to repopulate its node collection.
# First, create a new section, and then append it as a child to the root document node.
section = aw.Section(doc)
doc.append_child(section)
# Set some page setup properties for the section.
section.page_setup.section_start = aw.SectionStart.NEW_PAGE
section.page_setup.paper_size = aw.PaperSize.LETTER
# A section needs a body, which will contain and display all its contents
# on the page between the section's header and footer.
body = aw.Body(doc)
section.append_child(body)
# Create a paragraph, set some formatting properties, and then append it as a child to the body.
para = aw.Paragraph(doc)
para.paragraph_format.style_name = 'Heading 1'
para.paragraph_format.alignment = aw.ParagraphAlignment.CENTER
body.append_child(para)
# Finally, add some content to do the document. Create a run,
# set its appearance and contents, and then append it as a child to the paragraph.
run = aw.Run(doc=doc)
run.text = 'Hello World!'
run.font.color = aspose.pydrawing.Color.red
para.append_child(run)
self.assertEqual('Hello World!', doc.get_text().strip())
doc.save(file_name=ARTIFACTS_DIR + 'Section.CreateManually.docx')
