+ + + + + +Examples +of use +

Text objects can be used for a variety of purposes. Some examples throughout +the Symbian platform and its standard applications include:

+
    +
  • word processor documents

    A +word processor document is a single rich text object, containing fields, pictures +and styles. This is the "classic" use of text content and views.

  • +
  • spreadsheet cells

    A +spreadsheet contains a number of global text cells, each of which shares a +common paragraph and character format layer. This enables the text to be maintained +by text content and displayed using text views, but avoids duplicating format +layers.

  • +
  • editor controls

    Editors +for rich and global text provide the functionality needed for editing text +objects, descriptors, and even text representations of floating point numbers +etc.

  • +
  • agenda views

    The +complex requirements of the day view in the agenda application are met by +putting all text into a single rich text object, with appropriate formatting. +This allows the powerful facilities of text views to format the display neatly, +including such facilities as slot squashing, rounded highlights on bullets +etc.

    When an individual entry is edited, its own data is edited in +a separate rich text object. This is later pasted back into the view.

  • +
  • things which can contain +embedded objects

    Since rich text contains pictures, and rich text editors +allow these to be edited, any application can contain pictures in its data, +and can therefore embed objects, simply by using rich text to store its entry +data. Both the agenda and the database may contain rich text objects, which +allows their entries to contain pictures.
