The text +can be arbitrarily constrained using a <a href="#validator">validator</a>() or an +<a href="#inputMask">inputMask</a>(), or both. +<p> A related class is <a href="qtextedit.html">QTextEdit</a> which allows multi-line, rich-text +editing. +<p> You can change the text with <a href="#setText">setText</a>() or <a href="#insert">insert</a>(). The text is +retrieved with <a href="#text">text</a>(); the displayed text (which may be different, +see <a href="#EchoMode-enum">EchoMode</a>) is retrieved with <a href="#displayText">displayText</a>(). Text can be +selected with <a href="#setSelection">setSelection</a>() or <a href="#selectAll">selectAll</a>(), and the selection can +be <a href="#cut">cut</a>(), <a href="#copy">copy</a>()ied and <a href="#paste">paste</a>()d. The text can be aligned with +<a href="#setAlignment">setAlignment</a>(). +<p> When the text changes the <a href="#textChanged">textChanged</a>() signal is emitted; when +the Return or Enter key is pressed the <a href="#returnPressed">returnPressed</a>() signal is +emitted. Note that if there is a validator set on the line edit, +the returnPressed() signal will only be emitted if the validator +returns <tt>Acceptable</tt>. +<p> By default, QLineEdits have a frame as specified by the Windows +and <a href="motif-extension.html#Motif">Motif</a> style guides; you can turn it off by calling +<a href="#setFrame">setFrame</a>(FALSE). +<p> The default key bindings are described below. The line edit also +provides a context menu (usually invoked by a right mouse click) +that presents some of these editing options. +<a name="desc"></a> +<center><table cellpadding="4" cellspacing="2" border="0"> +<tr bgcolor="#a2c511"> <th valign="top">Keypress <th valign="top">Action +<tr bgcolor="#f0f0f0"> <td valign="top">Left Arrow <td valign="top">Moves the cursor one character to the left. +<tr bgcolor="#d0d0d0"> <td valign="top">Shift+Left Arrow <td valign="top">Moves and selects text one character to the left. +<tr bgcolor="#f0f0f0"> <td valign="top">Right Arrow <td valign="top">Moves the cursor one character to the right. +<tr bgcolor="#d0d0d0"> <td valign="top">Shift+Right Arrow <td valign="top">Moves and selects text one character to the right. +<tr bgcolor="#f0f0f0"> <td valign="top">Home <td valign="top">Moves the cursor to the beginning of the line. +<tr bgcolor="#d0d0d0"> <td valign="top">End <td valign="top">Moves the cursor to the end of the line. +<tr bgcolor="#f0f0f0"> <td valign="top">Backspace <td valign="top">Deletes the character to the left of the cursor. +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+Backspace <td valign="top">Deletes the word to the left of the cursor. +<tr bgcolor="#f0f0f0"> <td valign="top">Delete <td valign="top">Deletes the character to the right of the cursor. +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+Delete <td valign="top">Deletes the word to the right of the cursor. +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+A <td valign="top">Moves the cursor to the beginning of the line. +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+B <td valign="top">Moves the cursor one character to the left. +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+C <td valign="top">Copies the selected text to the clipboard. +(Windows also supports Ctrl+Insert for this operation.) +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+D <td valign="top">Deletes the character to the right of the cursor. +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+E <td valign="top">Moves the cursor to the end of the line. +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+F <td valign="top">Moves the cursor one character to the right. +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+H <td valign="top">Deletes the character to the left of the cursor. +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+K <td valign="top">Deletes to the end of the line. +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+V <td valign="top">Pastes the clipboard text into line edit. +(Windows also supports Shift+Insert for this operation.) +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+X <td valign="top">Deletes the selected text and copies it to the clipboard. +(Windows also supports Shift+Delete for this operation.) +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+Z <td valign="top">Undoes the last operation. +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+Y <td valign="top">Redoes the last undone operation. +</table></center> +<p> Any other key sequence that represents a valid character, will +cause the character to be inserted into the line edit. +<p> <img src=qlined-m.png> <img src=qlined-w.png> +<p> <p>See also <a href="qtextedit.html">QTextEdit</a>, <a href="qlabel.html">QLabel</a>, <a href="qcombobox.html">QComboBox</a>, <a href="guibooks.html#fowler">GUI Design Handbook: Field, Entry</a>, and <a href="basic.html">Basic Widgets</a>. + +<hr><h2>Member Type Documentation</h2> +<h3 class=fn><a name="EchoMode-enum"></a>QLineEdit::EchoMode</h3> + +<p> This enum type describes how a line edit should display its +contents. +<ul> +<li><tt>QLineEdit::Normal</tt> - Display characters as they are entered.

Start the line edit without +the best default, and when the default is known, if modified() +returns FALSE (the user hasn't entered any text), insert the +default value. +<p> Calling <a href="#clearModified">clearModified</a>() or <a href="#setText">setText</a>() resets the modified flag to +FALSE. + +<p>Get this property's value with <a href="#isModified">isModified</a>(). +<h3 class=fn>bool <a name="readOnly-prop"></a>readOnly</h3> +<p>This property holds whether the line edit is read only. +<p>In read-only mode, the user can still copy the text to the +clipboard or drag-and-drop the text (if <a href="#echoMode">echoMode</a>() is <a href="#EchoMode-enum">Normal</a>), +but cannot edit it. +<p> QLineEdit does not show a cursor in read-only mode. +<p> <p>See also <a href="qwidget.html#enabled-prop">enabled</a>. + +<p>Set this property's value with <a href="#setReadOnly">setReadOnly</a>() and get this property's value with <a href="#isReadOnly">isReadOnly</a>(). +<h3 class=fn>bool <a name="redoAvailable-prop"></a>redoAvailable</h3> +<p>This property holds whether redo is available. +<p> +<p>Get this property's value with <a href="#isRedoAvailable">isRedoAvailable</a>(). +<h3 class=fn><a href="qstring.html">QString</a> <a name="selectedText-prop"></a>selectedText</h3> +<p>This property holds the selected text. +<p>If there is no selected text this property's value is +<a href="qstring.html#QString-null">QString::null</a>. +<p> <p>See also <a href="#hasSelectedText-prop">hasSelectedText</a>. + +<p>Get this property's value with <a href="#selectedText">selectedText</a>(). +<h3 class=fn><a href="qstring.html">QString</a> <a name="text-prop"></a>text</h3> +<p>This property holds the line edit's text. +<p>Note that setting this property clears the selection, clears the +undo/redo history, moves the cursor to the end of the line and +resets the <a href="#modified-prop">modified</a> property to FALSE.
