We strongly advise against using it in new code.<p> The QtMultiLineEdit widget provides multiple line text input and display.It is intended for moderate amounts of text. There are no arbitrarylimitations, but if you try to handle megabytes of data, performancewill suffer.<p> Per default, the edit widget does not perform any wordwrapping. This can be adjusted by calling <a href="#setWordWrap">setWordWrap</a>(). Bothdynamic wrapping according to the visible width or a fixed number ofcharacter or pixels is supported.<p> The widget can be used to display text by calling <a href="#setReadOnly">setReadOnly</a>(TRUE).<p> The default key bindings are described in <a href="#keyPressEvent">keyPressEvent</a>(); they cannotbe customized except by inheriting the class.<p> <img src=qmlined-m.png> <img src=qmlined-w.png><hr><h2>Member Type Documentation</h2><h3 class=fn><a name="EchoMode-enum"></a>QtMultiLineEdit::EchoMode</h3> <p> This enum type describes the ways in which <a href="qlineedit.html">QLineEdit</a> can display itscontents. The currently defined values are: <ul><p> <li> Normal - display characters as they are entered. This isthe default.<p> <li> NoEcho - do not display anything.<p> <li> Password - display asterisks instead of the charactersactually entered.<p> </ul><p> <p>See also <a href="#echoMode-prop">echoMode</a>, <a href="#echoMode-prop">echoMode</a> and <a href="qlineedit.html#EchoMode-enum">QLineEdit::EchoMode</a>.<h3 class=fn><a name="WordWrap-enum"></a>QtMultiLineEdit::WordWrap</h3> <p> This enum describes the multiline edit's word wrap mode.<p> The following values are valid:<ul><li> NoWrap - no word wrap at all.<li> WidgetWidth - word wrap depending on the currentwidth of the editor widget<li> FixedPixelWidth - wrap according to a fix amountof pixels ( see <a href="#wrapColumnOrWidth">wrapColumnOrWidth</a>() )<li> FixedColumnWidth - wrap according to a fix charactercolumn. This is useful whenever you need formatted text thatcan also be displayed gracefully on devices with monospacedfonts, for example a standard VT100 terminal. In that casewrapColumnOrWidth() should typically be set to 80.</ul>⌨️ 快捷键说明
