Examples

Shows how to limit the editing rights of editable ranges to a specific group/user.

void Visitor()
{
    auto doc = MakeObject<Document>();
    doc->Protect(ProtectionType::ReadOnly, u"MyPassword");

    auto builder = MakeObject<DocumentBuilder>(doc);
    builder->Writeln(String(u"Hello world! Since we have set the document's protection level to read-only,") +
                     u" we cannot edit this paragraph without the password.");

    // When we write-protect documents, editable ranges allow us to pick specific areas that users may edit.
    // There are two mutually exclusive ways to narrow down the list of allowed editors.
    // 1 -  Specify a user:
    SharedPtr<EditableRange> editableRange = builder->StartEditableRange()->get_EditableRange();
    editableRange->set_SingleUser(u"john.doe@myoffice.com");
    builder->Writeln(String::Format(u"This paragraph is inside the first editable range, can only be edited by {0}.", editableRange->get_SingleUser()));
    builder->EndEditableRange();

    ASSERT_EQ(EditorType::Unspecified, editableRange->get_EditorGroup());

    // 2 -  Specify a group that allowed users are associated with:
    editableRange = builder->StartEditableRange()->get_EditableRange();
    editableRange->set_EditorGroup(EditorType::Administrators);
    builder->Writeln(String::Format(u"This paragraph is inside the first editable range, can only be edited by {0}.", editableRange->get_EditorGroup()));
    builder->EndEditableRange();

    ASSERT_EQ(String::Empty, editableRange->get_SingleUser());

    builder->Writeln(u"This paragraph is outside the editable range, and cannot be edited by anybody.");

    // Print details and contents of every editable range in the document.
    auto editableRangePrinter = MakeObject<ExEditableRange::EditableRangePrinter>();

    doc->Accept(editableRangePrinter);

    std::cout << editableRangePrinter->ToText() << std::endl;
