<div class="descr">
<h2>Detailed Description</h2>
<p>The QPlainTextEdit class provides a widget that is used to edit and display plain text.</p>
<a name="introduction-and-concepts"></a>
<h3>Introduction and Concepts</h3>
<p>QPlainTextEdit is an advanced viewer/editor supporting plain text. It is optimized to handle large documents and to respond quickly to user input.</p>
<p>QPlainText uses very much the same technology and concepts as <a href="qtextedit.html">QTextEdit</a>, but is optimized for plain text handling.</p>
<p>QPlainTextEdit works on paragraphs and characters. A paragraph is a formatted string which is word-wrapped to fit into the width of the widget. By default when reading plain text, one newline signifies a paragraph. A document consists of zero or more paragraphs. Paragraphs are separated by hard line breaks. Each character within a paragraph has its own attributes, for example, font and color.</p>
<p>The shape of the mouse cursor on a QPlainTextEdit is <a href="qt.html#CursorShape-enum">Qt::IBeamCursor</a> by default. It can be changed through the <a href="qabstractscrollarea.html#viewport">viewport</a>()'s cursor property.</p>
<a name="using-qplaintextedit-as-a-display-widget"></a>
<h3>Using QPlainTextEdit as a Display Widget</h3>
<p>The text is set or replaced using <a href="qplaintextedit.html#plainText-prop">setPlainText</a>() which deletes the existing text and replaces it with the text passed to <a href="qplaintextedit.html#plainText-prop">setPlainText</a>().</p>
<p>Text can be inserted using the <a href="qtextcursor.html">QTextCursor</a> class or using the convenience functions <a href="qplaintextedit.html#insertPlainText">insertPlainText</a>(), <a href="qplaintextedit.html#appendPlainText">appendPlainText</a>() or <a href="qplaintextedit.html#paste">paste</a>().</p>
<p>By default, the text edit wraps words at whitespace to fit within the text edit widget. The <a href="qplaintextedit.html#lineWrapMode-prop">setLineWrapMode</a>() function is used to specify the kind of line wrap you want, <a href="qplaintextedit.html#LineWrapMode-enum">WidgetWidth</a> or <a href="qplaintextedit.html#LineWrapMode-enum">NoWrap</a> if you don't want any wrapping. If you use word wrap to the widget's width <a href="qplaintextedit.html#LineWrapMode-enum">WidgetWidth</a>, you can specify whether to break on whitespace or anywhere with <a href="qplaintextedit.html#wordWrapMode-prop">setWordWrapMode</a>().</p>
<p>The <a href="qplaintextedit.html#find">find</a>() function can be used to find and select a given string within the text.</p>
<p>If you want to limit the total number of paragraphs in a QPlainTextEdit, as it is for example useful in a log viewer, then you can use the <a href="qplaintextedit.html#maximumBlockCount-prop">maximumBlockCount</a> property. The combination of <a href="qplaintextedit.html#maximumBlockCount-prop">setMaximumBlockCount</a>() and <a href="qplaintextedit.html#appendPlainText">appendPlainText</a>() turns QPlainTextEdit into an efficient viewer for log text. The scrolling can be reduced with the <a href="qplaintextedit.html#centerOnScroll-prop">centerOnScroll</a>() property, making the log viewer even faster. Text can be formatted in a limited way, either using a syntax highlighter (see below), or by appending html-formatted text with <a href="qplaintextedit.html#appendHtml">appendHtml</a>(). While QPlainTextEdit does not support complex rich text rendering with tables and floats, it does support limited paragraph-based formatting that you may need in a log viewer.</p>
<a name="read-only-key-bindings"></a>
<h4>Read-only Key Bindings</h4>
<p>When QPlainTextEdit is used read-only the key bindings are limited to navigation, and text may only be selected with the mouse:</p>
<table class="generic">
<thead><tr class="qt-style"><th >Keypresses</th><th >Action</th></tr></thead>
<tr valign="top" class="odd"><td ><a href="qt.html#ArrowType-enum">Qt::UpArrow</a></td><td >Moves one line up.</td></tr>
<tr valign="top" class="even"><td ><a href="qt.html#ArrowType-enum">Qt::DownArrow</a></td><td >Moves one line down.</td></tr>
<tr valign="top" class="odd"><td ><a href="qt.html#ArrowType-enum">Qt::LeftArrow</a></td><td >Moves one character to the left.</td></tr>
<tr valign="top" class="even"><td ><a href="qt.html#ArrowType-enum">Qt::RightArrow</a></td><td >Moves one character to the right.</td></tr>
<tr valign="top" class="odd"><td >PageUp</td><td >Moves one (viewport) page up.</td></tr>
<tr valign="top" class="even"><td >PageDown</td><td >Moves one (viewport) page down.</td></tr>
<tr valign="top" class="odd"><td >Home</td><td >Moves to the beginning of the text.</td></tr>
<tr valign="top" class="even"><td >End</td><td >Moves to the end of the text.</td></tr>
<tr valign="top" class="odd"><td >Alt+Wheel</td><td >Scrolls the page horizontally (the Wheel is the mouse wheel).</td></tr>
<tr valign="top" class="even"><td >Ctrl+Wheel</td><td >Zooms the text.</td></tr>
<tr valign="top" class="odd"><td >Ctrl+A</td><td >Selects all text.</td></tr>
</table>
<a name="using-qplaintextedit-as-an-editor"></a>
<h3>Using QPlainTextEdit as an Editor</h3>
<p>All the information about using QPlainTextEdit as a display widget also applies here.</p>
<p>Selection of text is handled by the <a href="qtextcursor.html">QTextCursor</a> class, which provides functionality for creating selections, retrieving the text contents or deleting selections. You can retrieve the object that corresponds with the user-visible cursor using the <a href="qplaintextedit.html#textCursor">textCursor</a>() method. If you want to set a selection in QPlainTextEdit just create one on a <a href="qtextcursor.html">QTextCursor</a> object and then make that cursor the visible cursor using <a href="qwidget.html#cursor-prop">setCursor</a>(). The selection can be copied to the clipboard with <a href="qplaintextedit.html#copy">copy</a>(), or cut to the clipboard with <a href="qplaintextedit.html#cut">cut</a>(). The entire text can be selected using <a href="qplaintextedit.html#selectAll">selectAll</a>().</p>

<h3>Differences to QTextEdit</h3>
<p>QPlainTextEdit is a thin class, implemented by using most of the technology that is behind <a href="qtextedit.html">QTextEdit</a> and <a href="qtextdocument.html">QTextDocument</a>. Its performance benefits over <a href="qtextedit.html">QTextEdit</a> stem mostly from using a different and simplified text layout called <a href="qplaintextdocumentlayout.html">QPlainTextDocumentLayout</a> on the text document (see <a href="qtextdocument.html#setDocumentLayout">QTextDocument::setDocumentLayout</a>()). The plain text document layout does not support tables nor embedded frames, and <i>replaces a pixel-exact height calculation with a line-by-line respectively paragraph-by-paragraph scrolling approach</i>. This makes it possible to handle significantly larger documents, and still resize the editor with line wrap enabled in real time. It also makes for a fast log viewer (see <a href="qplaintextedit.html#maximumBlockCount-prop">setMaximumBlockCount</a>()).</p>

<h3 class="fn"><a name="backgroundVisible-prop"></a><span class="name">backgroundVisible</span> : <span class="type">bool</span></h3>
<p>This property holds whether the palette background is visible outside the document area.</p>
<p>If set to true, the plain text edit paints the palette background on the viewport area not covered by the text document. Otherwise, if set to false, it won't. The feature makes it possible for the user to visually distinguish between the area of the document, painted with the base color of the palette, and the empty area not covered by any document.</p>
<p>The default is false.</p>

<p>If set to true, the plain text edit scrolls the document vertically to make the cursor visible at the center of the viewport. This also allows the text edit to scroll below the end of the document. Otherwise, if set to false, the plain text edit scrolls the smallest amount possible to ensure the cursor is visible.
