multi-line-lisp-text

Class

Package: common-graphics

Class and Control

Like a multi-line-editable-text control, except that the value may be any lisp object rather than a string only. When the control's value is set programmatically to a new arbitrary lisp object, pprint is called internally on the object to return a string to be displayed in the control. When the end user types into the control, read-from-string is called internally on the new string to produce a new arbitrary lisp object that is then stored as the value of the control. Errors are trapped during the reading so that no break will occur; if an error is signaled during the reading then nil is stored as the value of the control.
