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>2.</sup> + \row \i Text Viewer<sup>3.</sup> \i setReadOnly(TRUE) + \i 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().

If you use \c AutoText then setText() and + append() will try to determine whether the text they are given is + plain text or rich text. If you use \c RichText then setText() and + append() will assume that the text they are given is rich text. + insert() simply inserts the text it is given. QTextEdit works on paragraphs and characters. A paragraph is a formatted string which is word-wrapped to fit into the width of - the widget. 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. + the widget. By default when reading plain text, two newlines + 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. + + The text edit documentation uses the following concepts: + \list + \i \e{current format} -- + this is the format at the current cursor position, \e and it + is the format of the selected text if any. + \i \e{current paragraph} -- the paragraph which contains the + cursor. + \endlist QTextEdit can display images (using QMimeSourceFactory), 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(). Change the style sheet with \l{setStyleSheet()}; see + styleSheet(). Custom tags can be created and placed in a custom + style sheet. Change the style sheet with \l{setStyleSheet()}; see QStyleSheet for details. The images identified by image tags are displayed if they can be interpreted using the text edit's \l{QMimeSourceFactory}; see setMimeSourceFactory(). If you want a text browser with more navigation use QTextBrowser. If you just need to display a small piece of rich text use QLabel or QSimpleRichText. If you create a new QTextEdit, and want to allow the user to edit rich text, call setTextFormat(Qt::RichText) to ensure that the text is treated as rich text. (Rich text uses HTML tags to set text formatting attributes. See QStyleSheet 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(Qt::PlainText) to preserve such text. - The text edit documentation uses the following concepts: - \list - \i <i>current format</i> -- - this is the format at the current cursor position, \e and it - is the format of the selected text if any. - \i <i>current paragraph</i> -- the paragraph which contains the - cursor. - \endlist + Note that we do not intend to add a full-featured web browser + widget to Qt (because that would easily double Qt's size and only + a few applications would benefit from it). The rich + text support in Qt 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. + \section1 Using QTextEdit as a Display Widget + + QTextEdit can display a large HTML subset, including tables and + images. The text is set or replaced using setText() which deletes any existing text and replaces it with the text passed in the - setText() call. Text can be inserted with insert(), paste() and - pasteSubType(). 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). - - The current format's attributes are set with setItalic(), - setBold(), setUnderline(), setFamily() (font family), - setPointSize(), setColor() and setCurrentFont(). The current - paragraph's style is set with setParagType() and its 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(). QTextEdit 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. - - 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. - - QTextEdit 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 <em>Qt Designer</em>'s - code editor \e{Ctrl+I} invokes the indent() function. + 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). Loading and saving text is achieved using setText() and text(), for example: \code QFile file( fileName ); // Read the text from a file if ( file.open( IO_ReadOnly ) ) { QTextStream ts( &file ); textEdit->setText( ts.read() ); } \endcode \code QFile file( fileName ); // Write the text to a file if ( file.open( IO_WriteOnly ) ) { QTextStream ts( &file ); ts << textEdit->text(); textEdit->setModified( FALSE ); } \endcode 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 \c NoWrap if you don't want any wrapping. Call setWordWrap() to set a fixed pixel width \c FixedPixelWidth, or character column (e.g. 80 column) \c FixedColumnWidth with the pixels or columns specified with setWrapColumnOrWidth(). If you use word wrap to the widget's width \c WidgetWidth, you can specify whether to break on whitespace or anywhere with setWrapPolicy(). 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. Hypertext links are automatically underlined; this can be changed with setLinkUnderline(). The tab stop width is set with setTabStopWidth(). 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. 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(). You can scroll to an anchor in the text, e.g. \c{<a name="anchor">} with scrollToAnchor(). The find() function can be used to find and select a given string within the text. + A read-only QTextEdit provides the same functionality as the + (obsolete) QTextView. (QTextView is still supplied for + compatibility with old code.) + + \section2 Read-only key bindings + + When QTextEdit is used read-only the key-bindings are limited to + navigation, and text may only be selected with the mouse: + \table + \header \i Keypresses \i Action + \row \i \e{UpArrow} \i Move one line up + \row \i \e{DownArrow} \i Move one line down + \row \i \e{LeftArrow} \i Move one character left + \row \i \e{RightArrow} \i Move one character right + \row \i \e{PageUp} \i Move one (viewport) page up + \row \i \e{PageDown} \i Move one (viewport) page down + \row \i \e{Home} \i Move to the beginning of the text + \row \i \e{End} \i Move to the end of the text + \row \i \e{Shift+Wheel} \i Scroll the page horizontally (the Wheel is the mouse wheel) + \row \i \e{Ctrl+Wheel} \i Zoom the text + \endtable + + The text edit may be able to provide some meta-information. For + example, the documentTitle() function will return the text from + within HTML \c{<title>} tags. + + The text displayed in a text edit has a \e context. The context is + a path which the text edit's QMimeSourceFactory uses to resolve + the locations of files and images. It is passed to the + mimeSourceFactory() when quering data. (See QTextEdit() and + \l{context()}.) + + \section1 Using QTextEdit as an Editor + + All the information about using QTextEdit as a display widget also + applies here. + + The current format's attributes are set with setItalic(), + setBold(), setUnderline(), setFamily() (font family), + setPointSize(), setColor() and setCurrentFont().

It is + useful for code editors, for example in <em>Qt Designer</em>'s + code editor \e{Ctrl+I} invokes the indent() function. + + \section2 Editing key bindings + The list of key-bindings which are implemented for editing: \table \header \i Keypresses \i Action \row \i \e{Backspace} \i Delete the character to the left of the cursor \row \i \e{Delete} \i Delete the character to the right of the cursor \row \i \e{Ctrl+A} \i Move the cursor to the beginning of the line \row \i \e{Ctrl+B} \i Move the cursor one character left \row \i \e{Ctrl+C} \i Copy the marked text to the clipboard (also \e{Ctrl+Insert} under Windows) \row \i \e{Ctrl+D} \i Delete the character to the right of the cursor \row \i \e{Ctrl+E} \i Move the cursor to the end of the line \row \i \e{Ctrl+F} \i Move the cursor one character right \row \i \e{Ctrl+H} \i Delete the character to the left of the cursor \row \i \e{Ctrl+K} \i Delete to end of line \row \i \e{Ctrl+N} \i Move the cursor one line down \row \i \e{Ctrl+P} \i Move the cursor one line up \row \i \e{Ctrl+V} \i Paste the clipboard text into line edit (also \e{Shift+Insert} under Windows) \row \i \e{Ctrl+X} \i Cut the marked text, copy to clipboard (also \e{Shift+Delete} under Windows) \row \i \e{Ctrl+Z} \i Undo the last operation \row \i \e{Ctrl+Y} \i Redo the last operation \row \i \e{LeftArrow} \i Move the cursor one character left \row \i \e{Ctrl+LeftArrow} \i Move the cursor one word left \row \i \e{RightArrow} \i Move the cursor one character right \row \i \e{Ctrl+RightArrow} \i Move the cursor one word right \row \i \e{UpArrow} \i Move the cursor one line up \row \i \e{Ctrl+UpArrow} \i Move the cursor one word up \row \i \e{DownArrow} \i Move the cursor one line down \row \i \e{Ctrl+Down Arrow} \i Move the cursor one word down \row \i \e{PageUp} \i Move the cursor one page up \row \i \e{PageDown} \i Move the cursor one page down \row \i \e{Home} \i Move the cursor to the beginning of the line \row \i \e{Ctrl+Home} \i Move the cursor to the beginning of the text \row \i \e{End} \i Move the cursor to the end of the line \row \i \e{Ctrl+End} \i Move the cursor to the end of the text \row \i \e{Shift+Wheel} \i Scroll the page horizontally (the Wheel is the mouse wheel) \row \i \e{Ctrl+Wheel} \i Zoom the text \endtable To select (mark) text hold down the Shift key whilst pressing one of the movement keystrokes, for example, <i>Shift+Right Arrow</i> will select the character to the right, and <i>Shift+Ctrl+Right Arrow</i> will select the word to the right, etc. 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(). - QTextEdit can also be used as read-only text viewer. Call - setReadOnly( TRUE ) to disable editing. A read-only QTextEdit - provides the same functionality as the (obsolete) QTextView. - (QTextView is still supplied for compatibility with old code.) - - When QTextEdit is used read-only the key-bindings are limited to - navigation, and text may only be selected with the mouse: - \table - \header \i Keypresses \i Action - \row \i \e{UpArrow} \i Move one line up - \row \i \e{DownArrow} \i Move one line down - \row \i \e{LeftArrow} \i Move one character left - \row \i \e{RightArrow} \i Move one character right - \row \i \e{PageUp} \i Move one (viewport) page up - \row \i \e{PageDown} \i Move one (viewport) page down - \row \i \e{Home} \i Move to the beginning of the text - \row \i \e{End} \i Move to the end of the text - \row \i \e{Shift+Wheel} \i Scroll the page horizontally (the Wheel is the mouse wheel) - \row \i \e{Ctrl+Wheel} \i Zoom the text - \endtable - - The text edit may be able to provide some meta-information. For - example, the documentTitle() function will return the text from - within HTML \c{<title>} tags. - - The text displayed in a text edit has a \e context. The context is - a path which the text edit's QMimeSourceFactory uses to resolve - the locations of files and images. It is passed to the - mimeSourceFactory() when quering data. (See QTextEdit() and - \l{context()}.) - - Note that we do not intend to add a full-featured web browser - widget to Qt (because that would easily double Qt's size and only - a few applications would benefit from it). The rich - text support in Qt 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. */ /*! \enum QTextEdit::KeyboardAction This enum is used by doKeyboardAction() to specify which action should be executed: \value ActionBackspace Delete the character to the left of the cursor. \value ActionDelete Delete the character to the right of the cursor. \value ActionReturn Split the paragraph at the cursor position. \value ActionKill If the cursor is not at the end of the paragraph, delete the text from the cursor position until the end of the paragraph.
