Examples

Shows how to use a building block’s contents as a custom placeholder text for a structured document tag.

doc = aw.Document()
# Insert a plain text structured document tag of the "PLAIN_TEXT" type, which will function as a text box.
# The contents that it will display by default are a "Click here to enter text." prompt.
tag = aw.markup.StructuredDocumentTag(doc, aw.markup.SdtType.PLAIN_TEXT, aw.markup.MarkupLevel.INLINE)
# We can get the tag to display the contents of a building block instead of the default text.
# First, add a building block with contents to the glossary document.
glossary_doc = doc.glossary_document
substitute_block = aw.buildingblocks.BuildingBlock(glossary_doc)
substitute_block.name = 'Custom Placeholder'
substitute_block.append_child(aw.Section(glossary_doc))
substitute_block.first_section.append_child(aw.Body(glossary_doc))
substitute_block.first_section.body.append_paragraph('Custom placeholder text.')
glossary_doc.append_child(substitute_block)
# Then, use the structured document tag's "placeholder_name" property to reference that building block by name.
tag.placeholder_name = 'Custom Placeholder'
# If "placeholder_name" refers to an existing block in the parent document's glossary document,
# we will be able to verify the building block via the "placeholder" property.
self.assertEqual(substitute_block, tag.placeholder)
# Set the "is_showing_placeholder_text" property to "True" to treat the
# structured document tag's current contents as placeholder text.
# This means that clicking on the text box in Microsoft Word will immediately highlight all the tag's contents.
# Set the "is_showing_placeholder_text" property to "False" to get the
# structured document tag to treat its contents as text that a user has already entered.
# Clicking on this text in Microsoft Word will place the blinking cursor at the clicked location.
tag.is_showing_placeholder_text = is_showing_placeholder_text
builder = aw.DocumentBuilder(doc)
builder.insert_node(tag)
doc.save(ARTIFACTS_DIR + 'StructuredDocumentTag.placeholder_building_block.docx')
