+</h3> +<a name="1"></a><p> TQTextEdit is an advanced WYSIWYG viewer/editor supporting rich +text formatting using HTML-style tags. It is optimized to handle +large documents and to respond quickly to user input. +<p> TQTextEdit has four modes of operation: +<center><table cellpadding="4" cellspacing="2" border="0"> +<tr bgcolor="#a2c511"> <th valign="top">Mode <th valign="top">Command <th valign="top">Notes +<tr bgcolor="#f0f0f0"> <td valign="top">Plain Text Editor <td valign="top">setTextFormat(PlainText) +<td valign="top">Set text with <a href="#setText">setText</a>(); <a href="#text">text</a>() returns plain text. Text +attributes (e.g. colors) can be set, but plain text is always +returned. +<tr bgcolor="#d0d0d0"> <td valign="top">Rich Text Editor <td valign="top">setTextFormat(RichText) +<td valign="top">Set text with setText(); text() returns rich text. Rich +text editing is fairly limited. You can't set margins or +insert images for example (although you can read and +correctly display files that have margins set and that +include images). This mode is mostly useful for editing small +amounts of rich text. <sup>1.</sup> +<tr bgcolor="#f0f0f0"> <td valign="top">Text Viewer <td valign="top">setReadOnly(TRUE) +<td valign="top">Set text with setText() or <a href="#append">append</a>() (which has no undo +history so is faster and uses less memory); text() returns +plain or rich text depending on the <a href="#textFormat">textFormat</a>(). This mode +can correctly display a large subset of HTML tags. +<tr bgcolor="#d0d0d0"> <td valign="top">Log Viewer <td valign="top">setTextFormat(LogText) +<td valign="top">Append text using append(). The widget is set to be read +only and rich text support is disabled although a few HTML +tags (for color, bold, italic and underline) may be used. +(See <a href="#logtextmode">LogText mode</a> for details.) +</table></center> +<p> <sup>1.</sup><small>A more complete API that supports setting +margins, images, etc., is planned for a later TQt release.</small> +<p> TQTextEdit can be used as a syntax highlighting editor when used in +conjunction with <a href="ntqsyntaxhighlighter.html">TQSyntaxHighlighter</a>. +<p> We recommend that you always call <a href="#setTextFormat">setTextFormat</a>() to set the mode +you want to use. If you use <a href="ntqt.html#TextFormat-enum">AutoText</a> then <a href="#setText">setText</a>() and +<a href="#append">append</a>() will try to determine whether the text they are given is +plain text or rich text. If you use <a href="ntqt.html#TextFormat-enum">RichText</a> then setText() and +append() will assume that the text they are given is rich text. +<a href="#insert">insert</a>() simply inserts the text it is given. +<p> TQTextEdit 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 +signify a paragraph. A document consists of zero or more +paragraphs, indexed from 0. Characters are indexed on a +per-paragraph basis, also indexed from 0. The words in the +paragraph are aligned in accordance with the paragraph's +<a href="#alignment">alignment</a>(). Paragraphs are separated by hard line breaks. Each +character within a paragraph has its own attributes, for example, +font and color. +<p> The text edit documentation uses the following concepts: +<ul> +<li> <em>current format</em> -- +this is the format at the current cursor position, <em>and</em> it +is the format of the selected text if any. +<li> <em>current paragraph</em> -- the paragraph which contains the +cursor. +</ul> +<p> TQTextEdit can display images (using <a href="qmimesourcefactory.html">TQMimeSourceFactory</a>), lists and +tables. If the text is too large to view within the text edit's +viewport, scrollbars will appear. The text edit can load both +plain text and HTML files (a subset of HTML 3.2 and 4). The +rendering style and the set of valid tags are defined by a +<a href="#styleSheet">styleSheet</a>(). Custom tags can be created and placed in a custom +style sheet. Change the style sheet with <a href="#setStyleSheet">setStyleSheet</a>(); see +<a href="ntqstylesheet.html">TQStyleSheet</a> for details. The images identified by image tags are +displayed if they can be interpreted using the text edit's +<a href="qmimesourcefactory.html">TQMimeSourceFactory</a>; see <a href="#setMimeSourceFactory">setMimeSourceFactory</a>(). +<p> If you want a text browser with more navigation use <a href="tqtextbrowser.html">TQTextBrowser</a>. +If you just need to display a small piece of rich text use <a href="ntqlabel.html">TQLabel</a> +or <a href="ntqsimplerichtext.html">TQSimpleRichText</a>. +<p> If you create a new TQTextEdit, and want to allow the user to edit +rich text, call <a href="#setTextFormat">setTextFormat</a>(TQt::RichText) to ensure that the +text is treated as rich text. (Rich text uses HTML tags to set +text formatting attributes. See TQStyleSheet for information on the +HTML tags that are supported.). If you don't call setTextFormat() +explicitly the text edit will guess from the text itself whether +it is rich text or plain text. This means that if the text looks +like HTML or XML it will probably be interpreted as rich text, so +you should call setTextFormat(TQt::PlainText) to preserve such +text. +<p> Note that we do not intend to add a full-featured web browser +widget to TQt (because that would easily double TQt's size and only +a few applications would benefit from it). The rich +text support in TQt is designed to provide a fast, portable and +efficient way to add reasonable online help facilities to +applications, and to provide a basis for rich text editors. +<p> <h3> Using TQTextEdit as a Display Widget +</h3> +<a name="1-1"></a><p> TQTextEdit can display a large HTML subset, including tables and +images. +<p> The text is set or replaced using <a href="#setText">setText</a>() which deletes any +existing text and replaces it with the text passed in the +setText() call. If you call setText() with legacy HTML (with +<a href="#setTextFormat">setTextFormat</a>(RichText) in force), and then call <a href="#text">text</a>(), the text +that is returned may have different markup, but will render the +same. Text can be inserted with <a href="#insert">insert</a>(), <a href="#paste">paste</a>(), <a href="#pasteSubType">pasteSubType</a>() +and <a href="#append">append</a>(). Text that is appended does not go into the undo +history; this makes append() faster and consumes less memory. Text +can also be <a href="#cut">cut</a>(). The entire text is deleted with <a href="#clear">clear</a>() and the +selected text is deleted with <a href="#removeSelectedText">removeSelectedText</a>(). Selected +(marked) text can also be deleted with <a href="#del">del</a>() (which will delete +the character to the right of the cursor if no text is selected). +<p> Loading and saving text is achieved using <a href="#setText">setText</a>() and text(), +for example: +<pre> + <a href="ntqfile.html">TQFile</a> file( fileName ); // Read the text from a file + if ( file.<a href="ntqfile.html#open">open</a>( <a href="ntqfile.html#open">IO_ReadOnly</a> ) ) { + <a href="tqtextstream.html">TQTextStream</a> stream( &file ); + textEdit->setText( stream.<a href="tqtextstream.html#read">read</a>() ); + } + + <a href="ntqfile.html">TQFile</a> file( fileName ); // Write the text to a file + if ( file.<a href="ntqfile.html#open">open</a>( <a href="ntqfile.html#open">IO_WriteOnly</a> ) ) { + <a href="tqtextstream.html">TQTextStream</a> stream( &file ); + stream << textEdit->text(); + textEdit->setModified( FALSE ); + } + </pre> + +<p> By default the text edit wraps words at whitespace to fit within +the text edit widget. The <a href="#setWordWrap">setWordWrap</a>() function is used to +specify the kind of word wrap you want, or <a href="#WordWrap-enum">NoWrap</a> if you don't +want any wrapping. Call setWordWrap() to set a fixed pixel width +<a href="#WordWrap-enum">FixedPixelWidth</a>, or character column (e.g. 80 column) <a href="#WordWrap-enum">FixedColumnWidth</a> with the pixels or columns specified with +<a href="#setWrapColumnOrWidth">setWrapColumnOrWidth</a>(). If you use word wrap to the widget's width +<a href="#WordWrap-enum">WidgetWidth</a>, you can specify whether to break on whitespace or +anywhere with <a href="#setWrapPolicy">setWrapPolicy</a>(). +<p> The background color is set differently than other widgets, using +<a href="#setPaper">setPaper</a>(). You specify a brush style which could be a plain color +or a complex pixmap. +<p> Hypertext links are automatically underlined; this can be changed +with <a href="#setLinkUnderline">setLinkUnderline</a>(). The tab stop width is set with +<a href="#setTabStopWidth">setTabStopWidth</a>(). +<p> The <a href="#zoomIn">zoomIn</a>() and <a href="#zoomOut">zoomOut</a>() functions can be used to resize the +text by increasing (decreasing for zoomOut()) the point size used. +Images are not affected by the zoom functions. +<p> The <a href="#lines">lines</a>() function returns the number of lines in the text and +<a href="#paragraphs">paragraphs</a>() returns the number of paragraphs. The number of lines +within a particular paragraph is returned by <a href="#linesOfParagraph">linesOfParagraph</a>(). +The length of the entire text in characters is returned by +<a href="#length">length</a>(). +<p> You can scroll to an anchor in the text, e.g. +<tt><a name="anchor"></tt> with <a href="#scrollToAnchor">scrollToAnchor</a>(). The <a href="#find">find</a>() function +can be used to find and select a given string within the text. +<p> A read-only TQTextEdit provides the same functionality as the +(obsolete) TQTextView. (TQTextView is still supplied for +compatibility with old code.) +<p> <h4> Read-only key bindings +</h4> +<a name="1-1-1"></a><p> When TQTextEdit is used read-only the key-bindings are limited to +navigation, and text may only be selected with the mouse: +<center><table cellpadding="4" cellspacing="2" border="0"> +<tr bgcolor="#a2c511"> <th valign="top">Keypresses <th valign="top">Action +<tr bgcolor="#f0f0f0"> <td valign="top">UpArrow <td valign="top">Move one line up +<tr bgcolor="#d0d0d0"> <td valign="top">DownArrow <td valign="top">Move one line down +<tr bgcolor="#f0f0f0"> <td valign="top">LeftArrow <td valign="top">Move one character left +<tr bgcolor="#d0d0d0"> <td valign="top">RightArrow <td valign="top">Move one character right +<tr bgcolor="#f0f0f0"> <td valign="top">PageUp <td valign="top">Move one (viewport) page up +<tr bgcolor="#d0d0d0"> <td valign="top">PageDown <td valign="top">Move one (viewport) page down +<tr bgcolor="#f0f0f0"> <td valign="top">Home <td valign="top">Move to the beginning of the text +<tr bgcolor="#d0d0d0"> <td valign="top">End <td valign="top">Move to the end of the text +<tr bgcolor="#f0f0f0"> <td valign="top">Shift+Wheel +<td valign="top">Scroll the page horizontally (the Wheel is the mouse wheel) +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+Wheel <td valign="top">Zoom the text +</table></center> +<p> The text edit may be able to provide some meta-information. For +example, the <a href="#documentTitle">documentTitle</a>() function will return the text from +within HTML <tt><title></tt> tags. +<p> The text displayed in a text edit has a <em>context</em>. The context is +a path which the text edit's <a href="qmimesourcefactory.html">TQMimeSourceFactory</a> uses to resolve +the locations of files and images. It is passed to the +<a href="#mimeSourceFactory">mimeSourceFactory</a>() when quering data. (See TQTextEdit() and +<a href="#context">context</a>().) +<p> <a name="logtextmode"></a> +<h4> Using TQTextEdit in LogText Mode +</h4> +<a name="1-1-2"></a><p> Setting the text format to <a href="ntqt.html#TextFormat-enum">LogText</a> puts the widget in a special +mode which is optimized for very large texts. Editing, word wrap, +and rich text support are disabled in this mode (the widget is +explicitly made read-only). This allows the text to be stored in a +different, more memory efficient manner. However, a certain degree +of text formatting is supported through the use of formatting tags. +A tag is delimited by <tt><</tt> and <tt>></tt>. The characters <tt><</tt>, <tt>></tt> +and <tt>&</tt> are escaped by using <tt>&lt;</tt>, <tt>&gt;</tt> and <tt>&amp;</tt>. +A tag pair consists of a left and a right tag (or open/close tags). +Left-tags mark the starting point for formatting, while right-tags +mark the ending point. A right-tag always start with a <tt>/</tt> before +the tag keyword. For example <tt><b></tt> and <tt></b></tt> are a tag pair. +Tags can be nested, but they have to be closed in the same order as +they are opened. For example, <tt><b><u></u></b></tt> is valid, while <tt><b><u></b></u></tt> will output an error message. +<p> By using tags it is possible to change the color, bold, italic and +underline settings for a piece of text. A color can be specified +by using the HTML font tag <tt><font color=colorname></tt>. The color +name can be one of the color names from the X11 color database, or +a RGB hex value (e.g <tt>#00ff00</tt>). Example of valid color tags: +<tt><font color=red></tt>, <tt><font color="light blue"></tt>, <tt><font color="#223344"></tt>. Bold, italic and underline settings can be +specified by the tags <tt><b></tt>, <tt><i></tt> and <tt><u></tt>. Note that a +tag does not necessarily have to be closed. A valid example: +<pre> + This is <font color=red>red</font> while <b>this</b> is <font color=blue>blue</font>. + <font color=green><font color=yellow>Yellow,</font> and <u>green</u>. + </pre> + +<p> Stylesheets can also be used in LogText mode. To create and use a +custom tag, you could do the following: +<pre> + TQTextEdit * log = new TQTextEdit( this ); + log-><a href="#setTextFormat">setTextFormat</a>( TQt::<a href="ntqt.html#TextFormat-enum">LogText</a> ); + <a href="qstylesheetitem.html">TQStyleSheetItem</a> * item = new <a href="qstylesheetitem.html">TQStyleSheetItem</a>( log-><a href="#styleSheet">styleSheet</a>(), "mytag" ); + item-><a href="qstylesheetitem.html#setColor">setColor</a>( "red" ); + item-><a href="qstylesheetitem.html#setFontWeight">setFontWeight</a>( TQFont::Bold ); + item-><a href="qstylesheetitem.html#setFontUnderline">setFontUnderline</a>( TRUE ); + log-><a href="#append">append</a>( "This is a <mytag>custom tag</mytag>!" ); + </pre> + +Note that only the color, bold, underline and italic attributes of +a <a href="qstylesheetitem.html">TQStyleSheetItem</a> is used in LogText mode. +<p> Note that you can use <a href="#setMaxLogLines">setMaxLogLines</a>() to limit the number of +lines the widget can hold in LogText mode. +<p> There are a few things that you need to be aware of when the +widget is in this mode: +<ul> +<li> Functions that deal with rich text formatting and cursor +movement will not work or return anything valid. +<li> Lines are equivalent to paragraphs. +</ul> +<p> <h3> Using TQTextEdit as an Editor +</h3> +<a name="1-2"></a><p> All the information about using TQTextEdit as a display widget also +applies here. +<p> The current format's attributes are set with <a href="#setItalic">setItalic</a>(), +<a href="#setBold">setBold</a>(), <a href="#setUnderline">setUnderline</a>(), <a href="#setFamily">setFamily</a>() (font family), +<a href="#setPointSize">setPointSize</a>(), <a href="#setColor">setColor</a>() and <a href="#setCurrentFont">setCurrentFont</a>(). The current +paragraph's alignment is set with <a href="#setAlignment">setAlignment</a>(). +<p> Use <a href="#setSelection">setSelection</a>() to select text. The <a href="#setSelectionAttributes">setSelectionAttributes</a>() +function is used to indicate how selected text should be +displayed. Use <a href="#hasSelectedText">hasSelectedText</a>() to find out if any text is +selected. The currently selected text's position is available +using <a href="#getSelection">getSelection</a>() and the selected text itself is returned by +<a href="#selectedText">selectedText</a>(). The selection can be copied to the clipboard with +<a href="#copy">copy</a>(), or cut to the clipboard with <a href="#cut">cut</a>(). It can be deleted with +<a href="#removeSelectedText">removeSelectedText</a>(). The entire text can be selected (or +unselected) using <a href="#selectAll">selectAll</a>(). TQTextEdit supports multiple +selections. Most of the selection functions operate on the default +selection, selection 0. If the user presses a non-selecting key, +e.g. a cursor key without also holding down Shift, all selections +are cleared. +<p> Set and get the position of the cursor with <a href="#setCursorPosition">setCursorPosition</a>() +and <a href="#getCursorPosition">getCursorPosition</a>() respectively. When the cursor is moved, +the signals <a href="#currentFontChanged">currentFontChanged</a>(), <a href="#currentColorChanged">currentColorChanged</a>() and +<a href="#currentAlignmentChanged">currentAlignmentChanged</a>() are emitted to reflect the font, color +and alignment at the new cursor position. +<p> If the text changes, the <a href="#textChanged">textChanged</a>() signal is emitted, and if +the user inserts a new line by pressing Return or Enter, +<a href="#returnPressed">returnPressed</a>() is emitted. The <a href="#isModified">isModified</a>() function will return +TRUE if the text has been modified. +<p> TQTextEdit provides command-based undo and redo. To set the depth +of the command history use <a href="#setUndoDepth">setUndoDepth</a>() which defaults to 100 +steps. To undo or redo the last operation call <a href="#undo">undo</a>() or <a href="#redo">redo</a>(). +The signals <a href="#undoAvailable">undoAvailable</a>() and <a href="#redoAvailable">redoAvailable</a>() indicate whether +the undo and redo operations can be executed. +<p> The indent() function is used to reindent a paragraph. It is +useful for code editors, for example in <a href="designer-manual.html">TQt Designer</a>'s code editor <em>Ctrl+I</em> invokes the indent() +function. +<p> <h4> Editing key bindings +</h4> +<a name="1-2-1"></a><p> The list of key-bindings which are implemented for editing: +<center><table cellpadding="4" cellspacing="2" border="0"> +<tr bgcolor="#a2c511"> <th valign="top">Keypresses <th valign="top">Action +<tr bgcolor="#f0f0f0"> <td valign="top">Backspace <td valign="top">Delete the character to the left of the cursor +<tr bgcolor="#d0d0d0"> <td valign="top">Delete <td valign="top">Delete the character to the right of the cursor +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+A <td valign="top">Move the cursor to the beginning of the line +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+B <td valign="top">Move the cursor one character left +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+C <td valign="top">Copy the marked text to the clipboard (also +Ctrl+Insert under Windows) +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+D <td valign="top">Delete the character to the right of the cursor +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+E <td valign="top">Move the cursor to the end of the line +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+F <td valign="top">Move the cursor one character right +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+H <td valign="top">Delete the character to the left of the cursor +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+K <td valign="top">Delete to end of line +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+N <td valign="top">Move the cursor one line down +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+P <td valign="top">Move the cursor one line up +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+V <td valign="top">Paste the clipboard text into line edit +(also Shift+Insert under Windows) +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+X <td valign="top">Cut the marked text, copy to clipboard +(also Shift+Delete under Windows) +<tr bgcolor="#f0f0f0"> <td valign="top">Ctrl+Z <td valign="top">Undo the last operation +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+Y <td valign="top">Redo the last operation +<tr bgcolor="#f0f0f0"> <td valign="top">LeftArrow <td valign="top">Move the cursor one character left +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+LeftArrow <td valign="top">Move the cursor one word left +<tr bgcolor="#f0f0f0"> <td valign="top">RightArrow <td valign="top">Move the cursor one character right +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+RightArrow <td valign="top">Move the cursor one word right +<tr bgcolor="#f0f0f0"> <td valign="top">UpArrow <td valign="top">Move the cursor one line up +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+UpArrow <td valign="top">Move the cursor one word up +<tr bgcolor="#f0f0f0"> <td valign="top">DownArrow <td valign="top">Move the cursor one line down +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+Down Arrow <td valign="top">Move the cursor one word down +<tr bgcolor="#f0f0f0"> <td valign="top">PageUp <td valign="top">Move the cursor one page up +<tr bgcolor="#d0d0d0"> <td valign="top">PageDown <td valign="top">Move the cursor one page down +<tr bgcolor="#f0f0f0"> <td valign="top">Home <td valign="top">Move the cursor to the beginning of the line +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+Home <td valign="top">Move the cursor to the beginning of the text +<tr bgcolor="#f0f0f0"> <td valign="top">End <td valign="top">Move the cursor to the end of the line +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+End <td valign="top">Move the cursor to the end of the text +<tr bgcolor="#f0f0f0"> <td valign="top">Shift+Wheel <td valign="top">Scroll the page horizontally +(the Wheel is the mouse wheel) +<tr bgcolor="#d0d0d0"> <td valign="top">Ctrl+Wheel <td valign="top">Zoom the text +</table></center> +<p> To select (mark) text hold down the Shift key whilst pressing one +of the movement keystrokes, for example, <em>Shift+Right Arrow</em> +will select the character to the right, and <em>Shift+Ctrl+Right Arrow</em> will select the word to the right, etc. +<p> By default the text edit widget operates in insert mode so all +text that the user enters is inserted into the text edit and any +text to the right of the cursor is moved out of the way.
