Shows how to set outline levels for bookmarks.
doc = aw.Document()
builder = aw.DocumentBuilder(doc)
# Insert a bookmark with another bookmark nested inside it.
builder.start_bookmark('Bookmark 1')
builder.writeln('Text inside Bookmark 1.')
builder.start_bookmark('Bookmark 2')
builder.writeln('Text inside Bookmark 1 and 2.')
builder.end_bookmark('Bookmark 2')
builder.writeln('Text inside Bookmark 1.')
builder.end_bookmark('Bookmark 1')
# Insert another bookmark.
builder.start_bookmark('Bookmark 3')
builder.writeln('Text inside Bookmark 3.')

# When saving to .pdf, bookmarks can be accessed via a drop-down menu and used as anchors by most readers.
# Bookmarks can also have numeric values for outline levels,
# enabling lower level outline entries to hide higher-level child entries when collapsed in the reader.
pdf_save_options = aw.saving.PdfSaveOptions()
outline_levels = pdf_save_options.outline_options.bookmarks_outline_levels
outline_levels.add('Bookmark 1', 1)
outline_levels.add('Bookmark 2', 2)
outline_levels.add('Bookmark 3', 3)
self.assertEqual(3, outline_levels.count)
self.assertTrue(outline_levels.contains('Bookmark 1'))
self.assertEqual(1, outline_levels[0])
self.assertEqual(2, outline_levels.get_by_name('Bookmark 2'))
self.assertEqual(2, outline_levels.index_of_key('Bookmark 3'))
# We can remove two elements so that only the outline level designation for "Bookmark 1" is left.
outline_levels.remove_at(2)
outline_levels.remove('Bookmark 2')
# There are nine outline levels. Their numbering will be optimized during the save operation.
# In this case, levels "5" and "9" will become "2" and "3".
outline_levels.add('Bookmark 2', 5)
outline_levels.add('Bookmark 3', 9)
doc.save(file_name=ARTIFACTS_DIR + 'BookmarksOutlineLevelCollection.BookmarkLevels.pdf', save_options=pdf_save_options)
# Emptying this collection will preserve the bookmarks and put them all on the same outline level.
outline_levels.clear()
