340 \class QTextEdit-
341 \brief The QTextEdit class provides a widget that is used to edit and display-
342 both plain and rich text.-
343-
344 \ingroup richtext-processing-
345 \inmodule QtWidgets-
346-
347 \tableofcontents-
348-
349 \section1 Introduction and Concepts-
350-
351 QTextEdit is an advanced WYSIWYG viewer/editor supporting rich-
352 text formatting using HTML-style tags. It is optimized to handle-
353 large documents and to respond quickly to user input.-
354-
355 QTextEdit works on paragraphs and characters. A paragraph is a-
356 formatted string which is word-wrapped to fit into the width of-
357 the widget. By default when reading plain text, one newline-
358 signifies a paragraph. A document consists of zero or more-
359 paragraphs. The words in the paragraph are aligned in accordance-
360 with the paragraph's alignment. Paragraphs are separated by hard-
361 line breaks. Each character within a paragraph has its own-
362 attributes, for example, font and color.-
363-
364 QTextEdit can display images, lists and tables. If the text is-
365 too large to view within the text edit's viewport, scroll bars will-
366 appear. The text edit can load both plain text and rich text files.-
367 Rich text is described using a subset of HTML 4 markup, refer to the-
368 \l {Supported HTML Subset} page for more information.-
369-
370 If you just need to display a small piece of rich text use QLabel.-
371-
372 The rich text support in Qt is designed to provide a fast, portable and-
373 efficient way to add reasonable online help facilities to-
374 applications, and to provide a basis for rich text editors. If-
375 you find the HTML support insufficient for your needs you may consider-
376 the use of Qt WebKit, which provides a full-featured web browser-
377 widget.-
378-
379 The shape of the mouse cursor on a QTextEdit is Qt::IBeamCursor by default.-
380 It can be changed through the viewport()'s cursor property.-
381-
382 \section1 Using QTextEdit as a Display Widget-
383-
384 QTextEdit can display a large HTML subset, including tables and-
385 images.-
386-
387 The text is set or replaced using setHtml() which deletes any-
388 existing text and replaces it with the text passed in the-
389 setHtml() call. If you call setHtml() with legacy HTML, and then-
390 call toHtml(), the text that is returned may have different markup,-
391 but will render the same. The entire text can be deleted with clear().-
392-
393 Text itself can be inserted using the QTextCursor class or using the-
394 convenience functions insertHtml(), insertPlainText(), append() or-
395 paste(). QTextCursor is also able to insert complex objects like tables-
396 or lists into the document, and it deals with creating selections-
397 and applying changes to selected text.-
398-
399 By default the text edit wraps words at whitespace to fit within-
400 the text edit widget. The setLineWrapMode() function is used to-
401 specify the kind of line wrap you want, or \l NoWrap if you don't-
402 want any wrapping. Call setLineWrapMode() to set a fixed pixel width-
403 \l FixedPixelWidth, or character column (e.g. 80 column) \l-
404 FixedColumnWidth with the pixels or columns specified with-
405 setLineWrapColumnOrWidth(). If you use word wrap to the widget's width-
406 \l WidgetWidth, you can specify whether to break on whitespace or-
407 anywhere with setWordWrapMode().-
408-
409 The find() function can be used to find and select a given string-
410 within the text.-
411-
412 If you want to limit the total number of paragraphs in a QTextEdit,-
413 as for example it is often useful in a log viewer, then you can use-
414 QTextDocument's maximumBlockCount property for that.-
415-
416 \section2 Read-only Key Bindings-
417-
418 When QTextEdit is used read-only the key bindings are limited to-
419 navigation, and text may only be selected with the mouse:-
420 \table-
421 \header \li Keypresses \li Action-
422 \row \li Up \li Moves one line up.-
423 \row \li Down \li Moves one line down.-
424 \row \li Left \li Moves one character to the left.-
425 \row \li Right \li Moves one character to the right.-
426 \row \li PageUp \li Moves one (viewport) page up.-
427 \row \li PageDown \li Moves one (viewport) page down.-
428 \row \li Home \li Moves to the beginning of the text.-
429 \row \li End \li Moves to the end of the text.-
430 \row \li Alt+Wheel-
431 \li Scrolls the page horizontally (the Wheel is the mouse wheel).-
432 \row \li Ctrl+Wheel \li Zooms the text.-
433 \row \li Ctrl+A \li Selects all text.-
434 \endtable-
435-
436 The text edit may be able to provide some meta-information. For-
437 example, the documentTitle() function will return the text from-
438 within HTML \c{<title>} tags.-
439-
440 \note Zooming into HTML documents only works if the font-size is not set to a fixed size.-
441-
442 \section1 Using QTextEdit as an Editor-
443-
444 All the information about using QTextEdit as a display widget also-
445 applies here.-
446-
447 The current char format's attributes are set with setFontItalic(),-
448 setFontWeight(), setFontUnderline(), setFontFamily(),-
449 setFontPointSize(), setTextColor() and setCurrentFont(). The current-
450 paragraph's alignment is set with setAlignment().-
451-
452 Selection of text is handled by the QTextCursor class, which provides-
453 functionality for creating selections, retrieving the text contents or-
454 deleting selections. You can retrieve the object that corresponds with-
455 the user-visible cursor using the textCursor() method. If you want to set-
456 a selection in QTextEdit just create one on a QTextCursor object and-
457 then make that cursor the visible cursor using setTextCursor(). The selection-
458 can be copied to the clipboard with copy(), or cut to the clipboard with-
459 cut(). The entire text can be selected using selectAll().-
460-
461 When the cursor is moved and the underlying formatting attributes change,-
462 the currentCharFormatChanged() signal is emitted to reflect the new attributes-
463 at the new cursor position.-
464-
465 The textChanged() signal is emitted whenever the text changes (as a result-
466 of setText() or through the editor itself).-
467-
468 QTextEdit holds a QTextDocument object which can be retrieved using the-
469 document() method. You can also set your own document object using setDocument().-
470-
471 QTextDocument provides an \l {QTextDocument::isModified()}{isModified()}-
472 function which will return true if the text has been modified since it was-
473 either loaded or since the last call to setModified with false as argument.-
474 In addition it provides methods for undo and redo.-
475-
476 \section2 Drag and Drop-
477-
478 QTextEdit also supports custom drag and drop behavior. By default,-
479 QTextEdit will insert plain text, HTML and rich text when the user drops-
480 data of these MIME types onto a document. Reimplement-
481 canInsertFromMimeData() and insertFromMimeData() to add support for-
482 additional MIME types.-
483-
484 For example, to allow the user to drag and drop an image onto a QTextEdit,-
485 you could the implement these functions in the following way:-
486-
487 \snippet textdocument-imagedrop/textedit.cpp 0-
488-
489 We add support for image MIME types by returning true. For all other-
490 MIME types, we use the default implementation.-
491-
492 \snippet textdocument-imagedrop/textedit.cpp 1-
493-
494 We unpack the image from the QVariant held by the MIME source and insert-
495 it into the document as a resource.-
496-

505 \row \li Ctrl+Insert \li Copy the selected text to the clipboard.-
506 \row \li Ctrl+K \li Deletes to the end of the line.-
507 \row \li Ctrl+V \li Pastes the clipboard text into text edit.-
508 \row \li Shift+Insert \li Pastes the clipboard text into text edit.-
509 \row \li Ctrl+X \li Deletes the selected text and copies it to the clipboard.-
510 \row \li Shift+Delete \li Deletes the selected text and copies it to the clipboard.-
511 \row \li Ctrl+Z \li Undoes the last operation.-
512 \row \li Ctrl+Y \li Redoes the last operation.-
513 \row \li Left \li Moves the cursor one character to the left.-
514 \row \li Ctrl+Left \li Moves the cursor one word to the left.-
515 \row \li Right \li Moves the cursor one character to the right.-
516 \row \li Ctrl+Right \li Moves the cursor one word to the right.-
517 \row \li Up \li Moves the cursor one line up.-
518 \row \li Down \li Moves the cursor one line down.-
519 \row \li PageUp \li Moves the cursor one page up.-
520 \row \li PageDown \li Moves the cursor one page down.-
521 \row \li Home \li Moves the cursor to the beginning of the line.-
522 \row \li Ctrl+Home \li Moves the cursor to the beginning of the text.-
523 \row \li End \li Moves the cursor to the end of the line.-
524 \row \li Ctrl+End \li Moves the cursor to the end of the text.-
525 \row \li Alt+Wheel \li Scrolls the page horizontally (the Wheel is the mouse wheel).-
526 \endtable-
527-
528 To select (mark) text hold down the Shift key whilst pressing one-
529 of the movement keystrokes, for example, \e{Shift+Right}-
530 will select the character to the right, and \e{Shift+Ctrl+Right} will select the word to the right, etc.-
