// Description : This is a particular kind of PGItem that handles
|
|
// simple one-line or short multi-line text entries, of
|
|
// the sort where the user can type any string.
|
|
//
|
|
// A PGEntry does all of its internal manipulation on a
|
|
// wide string, so it can store the full Unicode
|
|
// character set. The interface can support either the
|
|
// wide string getters and setters, or the normal 8-bit
|
|
// string getters and setters, which use whatever
|
|
// encoding method is specified by the associated
|
|
// TextNode.
