This can be adjusted by calling setWordWrap(). Both - dynamic wrapping according to the visible width or a fixed number of - character or pixels is supported. - - The widget can be used to display text by calling setReadOnly(TRUE). - - The default key bindings are described in keyPressEvent(); they cannot - be customized except by inheriting the class. - - <img src=qmlined-m.png> <img src=qmlined-w.png> -*/ - -/* - \property TQtMultiLineEdit::numLines - \brief the number of lines in the multi-line edit - - numLines() returns the number of lines in the editor.
