It is optimized to handle - large documents and to respond quickly to user input. - - QTextEdit 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. 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. - - QTextEdit can display images, lists and tables. If the text is - too large to view within the text edit's viewport, scroll bars will - appear. The text edit can load both plain text and HTML files (a - subset of HTML 3.2 and 4). - - If you just need to display a small piece of rich text use QLabel. - - 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. If - you find the HTML support insufficient for your needs you may consider - the use of QtWebKit, which provides a full-featured web browser - widget. - - The shape of the mouse cursor on a QTextEdit is Qt::IBeamCursor by default. - It can be changed through the viewport()'s cursor property. - - \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 setHtml() which deletes any - existing text and replaces it with the text passed in the - setHtml() call. If you call setHtml() with legacy HTML, and then - call toHtml(), the text that is returned may have different markup, - but will render the same. The entire text can be deleted with clear(). - - Text itself can be inserted using the QTextCursor class or using the - convenience functions insertHtml(), insertPlainText(), append() or - paste(). QTextCursor is also able to insert complex objects like tables - or lists into the document, and it deals with creating selections - and applying changes to selected text. - - By default the text edit wraps words at whitespace to fit within - the text edit widget. The setLineWrapMode() function is used to - specify the kind of line wrap you want, or \l NoWrap if you don't - want any wrapping. Call setLineWrapMode() to set a fixed pixel width - \l FixedPixelWidth, or character column (e.g. 80 column) \l - FixedColumnWidth with the pixels or columns specified with - setLineWrapColumnOrWidth(). If you use word wrap to the widget's width - \l WidgetWidth, you can specify whether to break on whitespace or - anywhere with setWordWrapMode(). - - The find() function can be used to find and select a given string - within the text. - - If you want to limit the total number of paragraphs in a QTextEdit, - as it is for example open useful in a log viewer, then you can use - QTextDocument's maximumBlockCount property for that. - - \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 Up \i Moves one line up. - \row \i Down \i Moves one line down. - \row \i Left \i Moves one character to the left. - \row \i Right \i Moves one character to the right. - \row \i PageUp \i Moves one (viewport) page up. - \row \i PageDown \i Moves one (viewport) page down. - \row \i Home \i Moves to the beginning of the text. - \row \i End \i Moves to the end of the text. - \row \i Alt+Wheel - \i Scrolls the page horizontally (the Wheel is the mouse wheel). - \row \i Ctrl+Wheel \i Zooms the text. - \row \i Ctrl+A \i Selects all 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. - - \section1 Using QTextEdit as an Editor - - All the information about using QTextEdit as a display widget also - applies here. - - The current char format's attributes are set with setFontItalic(), - setFontWeight(), setFontUnderline(), setFontFamily(), - setFontPointSize(), setTextColor() and setCurrentFont(). The current - paragraph's alignment is set with setAlignment(). - - Selection of text is handled by the QTextCursor 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 textCursor() method. If you want to set - a selection in QTextEdit just create one on a QTextCursor object and - then make that cursor the visible cursor using setTextCursor(). The selection - can be copied to the clipboard with copy(), or cut to the clipboard with - cut(). The entire text can be selected using selectAll(). - - When the cursor is moved and the underlying formatting attributes change, - the currentCharFormatChanged() signal is emitted to reflect the new attributes - at the new cursor position. - - QTextEdit holds a QTextDocument object which can be retrieved using the - document() method. You can also set your own document object using setDocument(). - QTextDocument emits a textChanged() signal if the text changes and it also - provides a isModified() function which will return true if the text has been - modified since it was either loaded or since the last call to setModified - with false as argument. In addition it provides methods for undo and redo. - - \section2 Drag and Drop - - QTextEdit also supports custom drag and drop behavior. By default, - QTextEdit will insert plain text, HTML and rich text when the user drops - data of these MIME types onto a document. Reimplement - canInsertFromMimeData() and insertFromMimeData() to add support for - additional MIME types. - - For example, to allow the user to drag and drop an image onto a QTextEdit, - you could the implement these functions in the following way: - - \snippet doc/src/snippets/textdocument-imagedrop/textedit.cpp 0 - - We add support for image MIME types by returning true. For all other - MIME types, we use the default implementation. - - \snippet doc/src/snippets/textdocument-imagedrop/textedit.cpp 1 - - We unpack the image from the QVariant held by the MIME source and insert - it into the document as a resource. - - \section2 Editing Key Bindings - - The list of key bindings which are implemented for editing: - \table - \header \i Keypresses \i Action - \row \i Backspace \i Deletes the character to the left of the cursor. - \row \i Delete \i Deletes the character to the right of the cursor. - \row \i Ctrl+C \i Copy the selected text to the clipboard. - \row \i Ctrl+Insert \i Copy the selected text to the clipboard. - \row \i Ctrl+K \i Deletes to the end of the line. - \row \i Ctrl+V \i Pastes the clipboard text into text edit. - \row \i Shift+Insert \i Pastes the clipboard text into text edit. - \row \i Ctrl+X \i Deletes the selected text and copies it to the clipboard. - \row \i Shift+Delete \i Deletes the selected text and copies it to the clipboard. - \row \i Ctrl+Z \i Undoes the last operation. - \row \i Ctrl+Y \i Redoes the last operation. - \row \i Left \i Moves the cursor one character to the left. - \row \i Ctrl+Left \i Moves the cursor one word to the left. - \row \i Right \i Moves the cursor one character to the right. - \row \i Ctrl+Right \i Moves the cursor one word to the right. - \row \i Up \i Moves the cursor one line up. - \row \i Down \i Moves the cursor one line down. - \row \i PageUp \i Moves the cursor one page up. - \row \i PageDown \i Moves the cursor one page down. - \row \i Home \i Moves the cursor to the beginning of the line. - \row \i Ctrl+Home \i Moves the cursor to the beginning of the text. - \row \i End \i Moves the cursor to the end of the line. - \row \i Ctrl+End \i Moves the cursor to the end of the text. - \row \i Alt+Wheel \i Scrolls the page horizontally (the Wheel is the mouse wheel). - \endtable - - To select (mark) text hold down the Shift key whilst pressing one - of the movement keystrokes, for example, \e{Shift+Right} - will select the character to the right, and \e{Shift+Ctrl+Right} will select the word to the right, etc. - - \sa QTextDocument, QTextCursor, {Application Example}, - {Syntax Highlighter Example}, {Rich Text Processing} -*/ - -/*! - \property QTextEdit::plainText - \since 4.3 - - This property gets and sets the text editor's contents as plain - text.
