CHAPTER 8

Text and Ink Input and Display

8-28 Using Text

If you want to open one of these keyboards programmatically, use code like the

following to send it the

Open message:

Getroot().alphaKeyboard:Open()

The keystrokes entered by the user are sent to the current key receiver view.

There can be only one key receiver at a time, and only views of the classes

clParagraphView and clEditView can be key receiver views. When a

keyboard is open, a caret is shown in the key receiver view at the location where

characters will be inserted.

The keyboard views are based on

clKeyboardView, which is described in

“Keyboard View (clKeyboardView)” (page 7-35) in Newton Programmer’s

Reference.

protoKeyboard 8

This proto creates a keyboard view that ﬂoats above all other views. It is centered

within its parent view and appears in a location that won’t obscure the

key-receiving view (normally, the view to which the keystrokes from the keyboard

are to be sent). The user can drag the keyboard view by its drag-dot to a different

location, if desired. Figure 8-10 shows an example of what a

protoKeyboard

looks like on the screen.
