+ \class TQtMultiLineEdit qtmultilineedit.h
+
+ \brief The TQtMultiLineEdit widget is a simple editor for inputting text.
+
+ \obsolete
+
+ The TQtMultiLineEdit widget provides multiple line text input and display.
+ It is intended for moderate amounts of text. There are no arbitrary
+ limitations, but if you try to handle megabytes of data, performance
+ will suffer.
+
+ Per default, the edit widget does not perform any word
+ wrapping. 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.

+/*
+ \property TQtMultiLineEdit::numLines
+ \brief the number of lines in the multi-line edit
+
+ numLines() returns the number of lines in the editor. The count
+ includes any empty lines at top and bottom, so for an empty editor
+ this method will return 1.
+*/
+/*
+ \property TQtMultiLineEdit::atBeginning
+ \brief whether the cursor is at the beginning
+
+ atBeginning() returns TRUE if the cursor is placed at the
+ beginning of the text.
+*/
+/*
+ \property TQtMultiLineEdit::atEnd
+ \brief whether the cursor is at the end
+
+ atEnd() returns TRUE if the cursor is placed at the end of the text.
+*/
+/*
+ \property TQtMultiLineEdit::maxLineWidth
+ \brief the maximum line width in pixels
+ Returns the width in pixels of the longest text line in this editor.

+/*

+ AlignRight.

+/*
+ \property TQtMultiLineEdit::edited
+ \brief whether the text had been edited
+
+edited() returns the edited flag of the line edit. If this returns FALSE,
+the contents has not been changed since the construction of the
+TQtMultiLineEdit (or the last call to setEdited( FALSE ), if any). If
+it returns TRUE, the contents have been edited, or setEdited( TRUE )
+has been called.
+
+setEdited() sets the edited flag of this line edit to \e e. The
+edited flag is never read by TQtMultiLineEdit, but is changed to TRUE
+whenever the user changes its contents.
+
+This is useful e.g. for things that need to provide a default value,
+but cannot find the default at once. Just open the widget without the
+best default and when the default is known, check the edited() return
+value and set the line edit's contents if the user has not started
+editing the line edit. Another example is to detect whether the
+contents need saving.

+
+ Note that excess lines are deleted from the \e bottom of the
+ lines. If you want teletype behaviour with lines disappearing
+ from the \e top as the limit is exceed, you probably just want
+ to use removeLine(0) prior to adding an excess line.

+/*
+ \property TQtMultiLineEdit::autoUpdate
+ \brief whether auto update is enabled
+
+ autoUpdate() returns TRUE if the view updates itself automatically
+ whenever it is changed in some way.
+
+ If autoUpdate() is TRUE (this is the default) then the editor updates
+ itself automatically whenever it has changed in some way (generally,
+ when text has been inserted or deleted).
+
+ If autoUpdate() is FALSE, the view does NOT repaint itself, or update
+ its internal state variables itself when it is changed. This can be
+ useful to avoid flicker during large changes, and is singularly
+ useless otherwise: Disable auto-update, do the changes, re-enable
+ auto-update, and call repaint().
+
+ \warning Do not leave the view in this state for a long time
+ (i.e. between events ). If, for example, the user interacts with the
+ view when auto-update is off, strange things can happen.
+
+ Setting auto-update to TRUE does not repaint the view, you must call
+ repaint() to do this (preferable repaint(FALSE) to avoid flicker).
