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.
l - l. Mode Command Notes Plain Text Editor setTextFormat(PlainText) Set text with setText(); text() returns plain text. Text attributes (e.g. colors) can be set, but plain text is always returned. Rich Text Editor setTextFormat(RichText) 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. Text Viewer setReadOnly(TRUE) Set text with setText() or append() (which has no undo history so is faster and uses less memory); text() returns plain or rich text depending on the textFormat(). This mode can correctly display a large subset of HTML tags. Log Viewer setTextFormat(LogText)
We recommend that you always call setTextFormat() to set the mode you want to use. If you use AutoText then setText() and append() will try to determine whether the text they are given is plain text or rich text. If you use RichText then setText() and append() will assume that the text they are given is rich text. insert() simply inserts the text it is given.
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 alignment(). Paragraphs are separated by hard line breaks. Each character within a paragraph has its own attributes, for example, font and color.
TQTextEdit can display images (using TQMimeSourceFactory), 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 styleSheet(). Custom tags can be created and placed in a custom style sheet. Change the style sheet with setStyleSheet(); see TQStyleSheet for details. The images identified by image tags are displayed if they can be interpreted using the text edit's TQMimeSourceFactory; see setMimeSourceFactory().
If you want a text browser with more navigation use TQTextBrowser. If you just need to display a small piece of rich text use QLabel or QSimpleRichText.
If you create a new TQTextEdit, and want to allow the user to edit rich text, call setTextFormat(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.
Note that we do not intend to add a full-featured web browser widget to TQt (because that would easily double Qt'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.
The text is set or replaced using setText() which deletes any existing text and replaces it with the text passed in the setText() call. If you call setText() with legacy HTML (with setTextFormat(RichText) in force), and then call text(), the text that is returned may have different markup, but will render the same. Text can be inserted with insert(), paste(), pasteSubType() and append(). Text that is appended does not go into the undo history; this makes append() faster and consumes less memory. Text can also be cut(). The entire text is deleted with clear() and the selected text is deleted with removeSelectedText(). Selected (marked) text can also be deleted with del() (which will delete the character to the right of the cursor if no text is selected).
.PP
Loading and saving text is achieved using setText() and text(), for example:
By default the text edit wraps words at whitespace to fit within the text edit widget. The setWordWrap() function is used to specify the kind of word wrap you want, or NoWrap if you don't want any wrapping. Call setWordWrap() to set a fixed pixel width FixedPixelWidth, or character column (e.g. 80 column) FixedColumnWidth with the pixels or columns specified with setWrapColumnOrWidth(). If you use word wrap to the widget's width WidgetWidth, you can specify whether to break on whitespace or anywhere with setWrapPolicy().
.PP
The background color is set differently than other widgets, using setPaper(). You specify a brush style which could be a plain color or a complex pixmap.
.PP
Hypertext links are automatically underlined; this can be changed with setLinkUnderline(). The tab stop width is set with setTabStopWidth().
.PP
The zoomIn() and zoomOut() 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.
.PP
The lines() function returns the number of lines in the text and paragraphs() returns the number of paragraphs. The number of lines within a particular paragraph is returned by linesOfParagraph(). The length of the entire text in characters is returned by length().
.PP
You can scroll to an anchor in the text, e.g. \fC<a name="anchor">\fR with scrollToAnchor(). The find() function can be used to find and select a given string within the text.

.PP
The text edit may be able to provide some meta-information. For example, the documentTitle() function will return the text from within HTML \fC<title>\fR tags.
The text displayed in a text edit has a \fIcontext\fR. The context is a path which the text edit's TQMimeSourceFactory uses to resolve the locations of files and images. It is passed to the mimeSourceFactory() when quering data. (See TQTextEdit() and context().)
Setting the text format to LogText 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 \fC<\fR and \fC>\fR. The characters \fC<\fR, \fC>\fR and \fC&\fR are escaped by using \fC<\fR, \fC>\fR and \fC&\fR. 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 \fC/\fR before the tag keyword. For example \fC<b>\fR and \fC</b>\fR are a tag pair. Tags can be nested, but they have to be closed in the same order as they are opened. For example, \fC<b><u></u></b>\fR is valid, while \fC<b><u></b></u>\fR will output an error message.
.PP
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 \fC<font color=colorname>\fR. The color name can be one of the color names from the X11 color database, or a RGB hex value (e.g \fC#00ff00\fR). Example of valid color tags: \fC<font color=red>\fR, \fC<font color="light blue">\fR, \fC<font color="#223344">\fR. Bold, italic and underline settings can be specified by the tags \fC<b>\fR, \fC<i>\fR and \fC<u>\fR. Note that a tag does not necessarily have to be closed. A valid example:
.PP
.nf
.br
This is <font color=red>red</font> while <b>this</b> is <font color=blue>blue</font>.
.br
<font color=green><font color=yellow>Yellow,</font> and <u>green</u>.
.br
.fi
.PP
Stylesheets can also be used in LogText mode. To create and use a custom tag, you could do the following:
The current format's attributes are set with setItalic(), setBold(), setUnderline(), setFamily() (font family), setPointSize(), setColor() and setCurrentFont(). The current paragraph's alignment is set with setAlignment().
Use setSelection() to select text. The setSelectionAttributes() function is used to indicate how selected text should be displayed. Use hasSelectedText() to find out if any text is selected. The currently selected text's position is available using getSelection() and the selected text itself is returned by selectedText(). The selection can be copied to the clipboard with copy(), or cut to the clipboard with cut(). It can be deleted with removeSelectedText(). The entire text can be selected (or unselected) using selectAll(). 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.
Set and get the position of the cursor with setCursorPosition() and getCursorPosition() respectively. When the cursor is moved, the signals currentFontChanged(), currentColorChanged() and currentAlignmentChanged() are emitted to reflect the font, color and alignment at the new cursor position.
.PP
If the text changes, the textChanged() signal is emitted, and if the user inserts a new line by pressing Return or Enter, returnPressed() is emitted. The isModified() function will return TRUE if the text has been modified.
TQTextEdit provides command-based undo and redo. To set the depth of the command history use setUndoDepth() which defaults to 100 steps. To undo or redo the last operation call undo() or redo(). The signals undoAvailable() and redoAvailable() indicate whether the undo and redo operations can be executed.
The indent() function is used to reindent a paragraph. It is useful for code editors, for example in TQt Designer's code editor \fICtrl+I\fR invokes the indent() function.

To select (mark) text hold down the Shift key whilst pressing one of the movement keystrokes, for example, \fIShift+Right Arrow\fR will select the character to the right, and \fIShift+Ctrl+Right Arrow\fR will select the word to the right, etc.
.PP
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. The mode can be changed to overwrite, where new text overwrites any text to the right of the cursor, using setOverwriteMode().
\fCTQTextEdit::ActionKill\fR - If the cursor is not at the end of the paragraph, delete the text from the cursor position until the end of the paragraph. If the cursor is at the end of the paragraph, delete the hard line break at the end of the paragraph: this will cause this paragraph to be joined with the following paragraph.
\fCTQTextEdit::WidgetWidth\fR - Wrap the text at the current width of the widget (this is the default). Wrapping is at whitespace by default; this can be changed with setWrapPolicy().
\fCTQTextEdit::FixedPixelWidth\fR - Wrap the text at a fixed number of pixels from the widget's left side. The number of pixels is set with wrapColumnOrWidth().
\fCTQTextEdit::FixedColumnWidth\fR - Wrap the text at a fixed number of character columns from the widget's left side. The number of characters is set with wrapColumnOrWidth(). This is useful if you need formatted text that can also be displayed gracefully on devices with monospaced fonts, for example a standard VT100 terminal, where you might set wrapColumnOrWidth() to 80.
The \fIcontext\fR is a path which the text edit's TQMimeSourceFactory uses to resolve the locations of files and images. It is passed to the mimeSourceFactory() when quering data.
For example if the text contains an image tag, \fC<img src="image.png">\fR, and the context is "path/to/look/in", the TQMimeSourceFactory will try to load the image from" path/to/look/in/image.png". If the tag was \fC<img src="/image.png">\fR, the context will not be used (because TQMimeSourceFactory recognizes that we have used an absolute path) and will try to load "/image.png". The context is applied in exactly the same way to \fIhrefs\fR, for example, \fC<a href="target.html">Target</a>\fR, would resolve to" path/to/look/in/target.html".
If there is an anchor at position \fIpos\fR (in contents coordinates), the text for attribute \fIattr\fR is returned, otherwise TQString::null is returned.
Appends a new paragraph with \fItext\fR to the end of the text edit. Note that the undo/redo history is cleared by this function, and no undo history is kept for appends which makes them faster than insert()s. If you want to append text which is added to the undo/redo history as well, use insertParagraph().
.PP
Examples:
.)l network/clientserver/client/client.cpp, network/clientserver/server/server.cpp, network/httpd/httpd.cpp, and process/process.cpp.
Returns the index of the character (relative to its paragraph) at position \fIpos\fR (in contents coordinates). If \fIpara\fR is not 0, \fI*para\fR is set to the character's paragraph.
Returns the context of the text edit. The context is a path which the text edit's TQMimeSourceFactory uses to resolve the locations of files and images.
This signal is emitted when text is selected or de-selected in the text edit.
.PP
When text is selected this signal will be emitted with \fIyes\fR set to TRUE. If no text has been selected or if the selected text is de-selected this signal is emitted with \fIyes\fR set to FALSE.
.PP
If \fIyes\fR is TRUE then copy() can be used to copy the selection to the clipboard. If \fIyes\fR is FALSE then copy() does nothing.
This function is called to create a right mouse button popup menu at the document position \fIpos\fR. If you want to create a custom popup menu, reimplement this function and return the created popup menu. Ownership of the popup menu is transferred to the caller.
\fBWarning:\fR The TQPopupMenu ID values 0-7 are reserved, and they map to the standard operations. When inserting items into your custom popup menu, be sure to specify ID values larger than 7.
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.PP
This function is called to create a right mouse button popup menu. If you want to create a custom popup menu, reimplement this function and return the created popup menu. Ownership of the popup menu is transferred to the caller.
.PP
This function is only called if createPopupMenu( const QPoint & ) returns 0.
This signal is emitted if the position of the cursor has changed. \fIpara\fR contains the paragraph index and \fIpos\fR contains the character position within the paragraph.
If there is some selected text (in selection 0) it is deleted. If there is no selected text (in selection 0) the character to the right of the text cursor is deleted.
Finds the next occurrence of the string, \fIexpr\fR. Returns TRUE if \fIexpr\fR was found; otherwise returns FALSE.
.PP
If \fIpara\fR and \fIindex\fR are both 0 the search begins from the current cursor position. If \fIpara\fR and \fIindex\fR are both not 0, the search begins from the \fI*index\fR character position in the \fI*para\fR paragraph.
.PP
If \fIcs\fR is TRUE the search is case sensitive, otherwise it is case insensitive. If \fIwo\fR is TRUE the search looks for whole word matches only; otherwise it searches for any matching text. If \fIforward\fR is TRUE (the default) the search works forward from the starting position to the end of the text, otherwise it works backwards to the beginning of the text.
.PP
If \fIexpr\fR is found the function returns TRUE. If \fIindex\fR and \fIpara\fR are not 0, the number of the paragraph in which the first character of the match was found is put into \fI*para\fR, and the index position of that character within the paragraph is put into \fI*index\fR.
.PP
If \fIexpr\fR is not found the function returns FALSE. If \fIindex\fR and \fIpara\fR are not 0 and \fIexpr\fR is not found, \fI*index\fR and \fI*para\fR are undefined.
.PP
Please note that this function will make the next occurrence of the string (if found) the current selection, and will thus modify the cursor position.
.PP
Using the \fIpara\fR and \fIindex\fR parameters will not work correctly in case the document contains tables.
Reimplemented to allow tabbing through links. If \fIn\fR is TRUE the tab moves the focus to the next child; if \fIn\fR is FALSE the tab moves the focus to the previous child. Returns TRUE if the focus was moved; otherwise returns FALSE.
If there is a selection, \fI*paraFrom\fR is set to the number of the paragraph in which the selection begins and \fI*paraTo\fR is set to the number of the paragraph in which the selection ends. (They could be the same.) \fI*indexFrom\fR is set to the index at which the selection begins within \fI*paraFrom\fR, and \fI*indexTo\fR is set to the index at which the selection ends within \fI*paraTo\fR.
.PP
If there is no selection, \fI*paraFrom\fR, \fI*indexFrom\fR, \fI*paraTo\fR and \fI*indexTo\fR are all set to -1.
.PP
If \fIparaFrom\fR, \fIindexFrom\fR, \fIparaTo\fR or \fIindexTo\fR is 0 this function does nothing.
.PP
The \fIselNum\fR is the number of the selection (multiple selections are supported). It defaults to 0 (the default selection).
The \fIinsertionFlags\fR define how the text is inserted. If RedoIndentation is set, the paragraph is re-indented. If CheckNewLines is set, newline characters in \fItext\fR result in hard line breaks (i.e. new paragraphs). If \fCcheckNewLine\fR is not set, the behaviour of the editor is undefined if the \fItext\fR contains newlines. (It is not possible to change TQTextEdit's newline handling behavior, but you can use TQString::replace() to preprocess text before inserting it.) If RemoveSelected is set, any selected text (in selection 0) is removed before the text is inserted.
Inserts \fItext\fR as a new paragraph at position \fIpara\fR. If \fIpara\fR is -1, the text is appended. Use append() if the append operation is performance critical.
Returns the line number of the line in paragraph \fIpara\fR in which the character at position \fIindex\fR appears. The \fIindex\fR position is relative to the beginning of the paragraph. If there is no such paragraph or no such character at the \fIindex\fR position (e.g. the index is out of range) -1 is returned.
Returns the number of lines in the text edit; this could be 0.
.PP
\fBWarning:\fR This function may be slow. Lines change all the time during word wrapping, so this function has to iterate over all the paragraphs and get the number of lines from each one individually.
Returns the maximum number of lines TQTextEdit can hold in LogText mode. By default the number of lines is unlimited, which is signified by a value of -1.
This signal is emitted when the modification status of the document has changed. If \fIm\fR is TRUE, the document was modified, otherwise the modification state has been reset to unmodified.
Moves the text cursor according to \fIaction\fR. This is normally used by some key event handler. \fIselect\fR specifies whether the text between the current cursor position and the new position should be selected.
Pastes the text with format \fIsubtype\fR from the clipboard into the text edit at the current cursor position. The \fIsubtype\fR can be" plain" or "html".
.PP
If there is no text with format \fIsubtype\fR in the clipboard nothing happens.
Places the cursor \fIc\fR at the character which is closest to position \fIpos\fR (in contents coordinates). If \fIc\fR is 0, the default text cursor is used.
This signal is emitted when the availability of redo changes. If \fIyes\fR is TRUE, then redo() will work until redoAvailable( FALSE ) is next emitted.
Scrolls the text edit to make the text at the anchor called \fIname\fR visible, if it can be found in the document. If the anchor isn't found no scrolling will occur. An anchor is defined using the HTML anchor tag, e.g. \fC<a name="target">\fR.
If \fIselect\fR is TRUE (the default), all the text is selected as selection 0. If \fIselect\fR is FALSE any selected text is unselected, i.e. the default selection (selection 0) is cleared.
Returns the selected text (from selection 0) or an empty string if there is no currently selected text (in selection 0). See the "selectedText" property for details.
Sets the alignment of the current paragraph to \fIa\fR. Valid alignments are TQt::AlignLeft, TQt::AlignRight, TQt::AlignJustify and TQt::AlignCenter (which centers horizontally).
.SH "void TQTextEdit::setMaxLogLines ( int limit )\fC [slot]\fR"
Sets the maximum number of lines a TQTextEdit can hold in LogText mode to \fIlimit\fR. If \fIlimit\fR is -1 (the default), this signifies an unlimited number of lines.
\fBWarning:\fR Never use formatting tags that span more than one line when the maximum log lines is set. When lines are removed from the top of the buffer it could result in an unbalanced tag pair, i.e. the left formatting tag is removed before the right one.
Sets a selection which starts at position \fIindexFrom\fR in paragraph \fIparaFrom\fR and ends at position \fIindexTo\fR in paragraph \fIparaTo\fR.
.PP
Any existing selections which have a different id (\fIselNum\fR) are left alone, but if an existing selection has the same id as \fIselNum\fR it is removed and replaced by this selection.
.PP
Uses the selection settings of selection \fIselNum\fR. If \fIselNum\fR is 0, this is the default selection.
.PP
The cursor is moved to the end of the selection if \fIselNum\fR is 0, otherwise the cursor position remains unchanged.
Sets the background color of selection number \fIselNum\fR to \fIback\fR and specifies whether the text of this selection should be inverted with \fIinvertText\fR.
.PP
This only works for \fIselNum\fR > 0. The default selection (\fIselNum\fR == 0) gets its attributes from the text edit's colorGroup().
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Changes the text of the text edit to the string \fItext\fR and the context to \fIcontext\fR. Any previous text is removed.
.PP
\fItext\fR may be interpreted either as plain text or as rich text, depending on the textFormat(). The default setting is AutoText, i.e. the text edit auto-detects the format from \fItext\fR.
The optional \fIcontext\fR is a path which the text edit's TQMimeSourceFactory uses to resolve the locations of files and images. (See TQTextEdit::TQTextEdit().) It is passed to the text edit's TQMimeSourceFactory when quering data.
TQTextEdit is optimized for large amounts text. One of its optimizations is to format only the visible text, formatting the rest on demand, e.g. as the user scrolls, so you don't usually need to call this function.
In some situations you may want to force the whole text to be formatted. For example, if after calling setText(), you wanted to know the height of the document (using contentsHeight()), you would call this function first.
This signal is emitted when the availability of undo changes. If \fIyes\fR is TRUE, then undo() will work until undoAvailable( FALSE ) is next emitted.
Zooms in on the text by making the base font size \fIrange\fR points larger and recalculating all font sizes to be the new size. This does not change the size of any images.

This property holds the text format: rich text, plain text, log text or auto text.
.PP
The text format is one of the following:
.TP
PlainText - all characters, except newlines, are displayed verbatim, including spaces. Whenever a newline appears in the text the text edit inserts a hard line break and begins a new paragraph.
AutoText - this is the default. The text edit autodetects which rendering style is best, PlainText or RichText. This is done by using the TQStyleSheet::mightBeRichText() function.
