Examples

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

auto doc = MakeObject<Document>();

// Insert a plain text structured document tag of the "PlainText" type, which will function as a text box.
// The contents that it will display by default are a "Click here to enter text." prompt.
auto tag = MakeObject<StructuredDocumentTag>(doc, SdtType::PlainText, 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.
SharedPtr<GlossaryDocument> glossaryDoc = doc->get_GlossaryDocument();

auto substituteBlock = MakeObject<BuildingBlock>(glossaryDoc);
substituteBlock->set_Name(u"Custom Placeholder");
substituteBlock->AppendChild(MakeObject<Section>(glossaryDoc));
substituteBlock->get_FirstSection()->AppendChild(MakeObject<Body>(glossaryDoc));
substituteBlock->get_FirstSection()->get_Body()->AppendParagraph(u"Custom placeholder text.");

glossaryDoc->AppendChild(substituteBlock);

// Then, use the structured document tag's "PlaceholderName" property to reference that building block by name.
tag->set_PlaceholderName(u"Custom Placeholder");

// If "PlaceholderName" 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.
ASPOSE_ASSERT_EQ(substituteBlock, tag->get_Placeholder());

// Set the "IsShowingPlaceholderText" 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 "IsShowingPlaceholderText" 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->set_IsShowingPlaceholderText(isShowingPlaceholderText);

auto builder = MakeObject<DocumentBuilder>(doc);
builder->InsertNode(tag);

doc->Save(ArtifactsDir + u"StructuredDocumentTag.PlaceholderBuildingBlock.docx");
