Protos / protoTXView

IsModified

protoTXView:IsModified()

Determines if the view has changed since the last call to either the *Externalize or *Internalize methods.

return value

A non-nil value if the contents of the view have changed since the last call to *Externalize or *Internalize. Returns nil if the contents have not been changed.

Note

For improved performance, you should only call the *Externalize method when *IsModified returns true.

Scrolling Methods

This section describes the methods that you can use for scrolling your word-processing views.

Note

The *protoTXView has built-in scrolling that happens automatically when the user is entering text with the keyboard or pen. You usually only have to call the methods described in this section if you have attached scroller protos to the view that encloses your *protoTXView.
