Paragraph views are normally lined to convey to the user that the view accepts text

input. To add the lined paper effect to paragraph views, see “Creating the Lined

Paper Effect in a Text View” (page 8-8).

Lightweight Paragraph Views 8

When you create a template using the clParagraphView class, and that

template is instantiated into a view at run time, the system may create a specialized

kind of paragraph view object, called a lightweight paragraph view. Lightweight

paragraph views have the advantage of requiring much less memory than do

standard paragraph views.

The system automatically creates a lightweight paragraph view instead of a

standard paragraph view if your template meets the following conditions:

■ The view must be read-only, which means that its viewFlags slot contains the

vReadOnly flag.

■ The view must not include any tabs, which means that the template does not

contain the

tabs slot.

■ The view must not include multiple font styles, which means that the template

does not contain the

styles slot; however, the view can contain a rich string in

its

text slot. For information about rich strings, see “Rich Strings” (page 8-22).

■ The viewFlags slot of the view must not contain the following ﬂags:

vGesturesAllowed, vCalculateBounds.

Note

Lightweight paragraph views can contain ink. ◆

Most paragraph views look the same after they are instantiated; that is, there is

not normally a way to tell whether a particular paragraph view is a standard or a

lightweight view. However, ink displayed in a lightweight paragraph view is

displayed in a ﬁxed font size.

Note

When laying out text in a lightweight paragraph view, the

viewLineSpacing value is ignored. This is not generally a

problem, since the line spacing dotted lines are normally used to

indicate that the text can be edited, and text in a lightweight

paragraph cannot be edited.
