346 \class QTextEdit-
347 \brief The QTextEdit class provides a widget that is used to edit and display-
348 both plain and rich text.-
349-
350 \ingroup richtext-processing-
351 \inmodule QtWidgets-
352-
353 \tableofcontents-
354-
355 \section1 Introduction and Concepts-
356-
357 QTextEdit is an advanced WYSIWYG viewer/editor supporting rich-
358 text formatting using HTML-style tags. It is optimized to handle-
359 large documents and to respond quickly to user input.-
360-
361 QTextEdit works on paragraphs and characters. A paragraph is a-
362 formatted string which is word-wrapped to fit into the width of-
363 the widget. By default when reading plain text, one newline-
364 signifies a paragraph. A document consists of zero or more-
365 paragraphs. The words in the paragraph are aligned in accordance-
366 with the paragraph's alignment. Paragraphs are separated by hard-
367 line breaks. Each character within a paragraph has its own-
368 attributes, for example, font and color.-
369-
370 QTextEdit can display images, lists and tables. If the text is-
371 too large to view within the text edit's viewport, scroll bars will-
372 appear. The text edit can load both plain text and rich text files.-
373 Rich text is described using a subset of HTML 4 markup, refer to the-
374 \l {Supported HTML Subset} page for more information.-
375-
376 If you just need to display a small piece of rich text use QLabel.-
377-
378 The rich text support in Qt is designed to provide a fast, portable and-
379 efficient way to add reasonable online help facilities to-
380 applications, and to provide a basis for rich text editors. If-
381 you find the HTML support insufficient for your needs you may consider-
382 the use of Qt WebKit, which provides a full-featured web browser-
383 widget.-
384-
385 The shape of the mouse cursor on a QTextEdit is Qt::IBeamCursor by default.-
386 It can be changed through the viewport()'s cursor property.-
387-
388 \section1 Using QTextEdit as a Display Widget-
389-
390 QTextEdit can display a large HTML subset, including tables and-
391 images.-
392-
393 The text is set or replaced using setHtml() which deletes any-
394 existing text and replaces it with the text passed in the-
395 setHtml() call. If you call setHtml() with legacy HTML, and then-
396 call toHtml(), the text that is returned may have different markup,-
397 but will render the same. The entire text can be deleted with clear().-
398-
399 Text itself can be inserted using the QTextCursor class or using the-
400 convenience functions insertHtml(), insertPlainText(), append() or-
401 paste(). QTextCursor is also able to insert complex objects like tables-
402 or lists into the document, and it deals with creating selections-
403 and applying changes to selected text.-
404-
405 By default the text edit wraps words at whitespace to fit within-
406 the text edit widget. The setLineWrapMode() function is used to-
407 specify the kind of line wrap you want, or \l NoWrap if you don't-
408 want any wrapping. Call setLineWrapMode() to set a fixed pixel width-
409 \l FixedPixelWidth, or character column (e.g. 80 column) \l-
410 FixedColumnWidth with the pixels or columns specified with-
411 setLineWrapColumnOrWidth(). If you use word wrap to the widget's width-
412 \l WidgetWidth, you can specify whether to break on whitespace or-
413 anywhere with setWordWrapMode().-
414-
415 The find() function can be used to find and select a given string-
416 within the text.-
417-
418 If you want to limit the total number of paragraphs in a QTextEdit,-
419 as for example it is often useful in a log viewer, then you can use-
420 QTextDocument's maximumBlockCount property for that.-
421-
422 \section2 Read-only Key Bindings-
423-
424 When QTextEdit is used read-only the key bindings are limited to-
425 navigation, and text may only be selected with the mouse:-
426 \table-
427 \header \li Keypresses \li Action-
428 \row \li Up \li Moves one line up.-
429 \row \li Down \li Moves one line down.-
430 \row \li Left \li Moves one character to the left.-
431 \row \li Right \li Moves one character to the right.-
432 \row \li PageUp \li Moves one (viewport) page up.-
433 \row \li PageDown \li Moves one (viewport) page down.-
434 \row \li Home \li Moves to the beginning of the text.-
435 \row \li End \li Moves to the end of the text.-
436 \row \li Alt+Wheel-
437 \li Scrolls the page horizontally (the Wheel is the mouse wheel).-
438 \row \li Ctrl+Wheel \li Zooms the text.-
439 \row \li Ctrl+A \li Selects all text.-
440 \endtable-
441-
442 The text edit may be able to provide some meta-information. For-
443 example, the documentTitle() function will return the text from-
444 within HTML \c{<title>} tags.-
445-
446 \note Zooming into HTML documents only works if the font-size is not set to a fixed size.-
447-
448 \section1 Using QTextEdit as an Editor-
449-
450 All the information about using QTextEdit as a display widget also-
451 applies here.-
452-
453 The current char format's attributes are set with setFontItalic(),-
454 setFontWeight(), setFontUnderline(), setFontFamily(),-
455 setFontPointSize(), setTextColor() and setCurrentFont(). The current-
456 paragraph's alignment is set with setAlignment().-
457-
458 Selection of text is handled by the QTextCursor class, which provides-
459 functionality for creating selections, retrieving the text contents or-
460 deleting selections. You can retrieve the object that corresponds with-
461 the user-visible cursor using the textCursor() method. If you want to set-
462 a selection in QTextEdit just create one on a QTextCursor object and-
463 then make that cursor the visible cursor using setTextCursor(). The selection-
464 can be copied to the clipboard with copy(), or cut to the clipboard with-
465 cut(). The entire text can be selected using selectAll().-
466-
467 When the cursor is moved and the underlying formatting attributes change,-
468 the currentCharFormatChanged() signal is emitted to reflect the new attributes-
469 at the new cursor position.-
470-
471 The textChanged() signal is emitted whenever the text changes (as a result-
472 of setText() or through the editor itself).-
473-
474 QTextEdit holds a QTextDocument object which can be retrieved using the-
475 document() method. You can also set your own document object using setDocument().-
476-
477 QTextDocument provides an \l {QTextDocument::isModified()}{isModified()}-
478 function which will return true if the text has been modified since it was-
479 either loaded or since the last call to setModified with false as argument.-
480 In addition it provides methods for undo and redo.-
481-
482 \section2 Drag and Drop-
483-
484 QTextEdit also supports custom drag and drop behavior. By default,-
485 QTextEdit will insert plain text, HTML and rich text when the user drops-
486 data of these MIME types onto a document. Reimplement-
487 canInsertFromMimeData() and insertFromMimeData() to add support for-
488 additional MIME types.-
489-
490 For example, to allow the user to drag and drop an image onto a QTextEdit,-
491 you could the implement these functions in the following way:-
492-
493 \snippet textdocument-imagedrop/textedit.cpp 0-
494-
495 We add support for image MIME types by returning true. For all other-
496 MIME types, we use the default implementation.-
497-
498 \snippet textdocument-imagedrop/textedit.cpp 1-
499-
500 We unpack the image from the QVariant held by the MIME source and insert-
501 it into the document as a resource.-

511 \row \li Ctrl+Insert \li Copy the selected text to the clipboard.-
512 \row \li Ctrl+K \li Deletes to the end of the line.-
513 \row \li Ctrl+V \li Pastes the clipboard text into text edit.-
514 \row \li Shift+Insert \li Pastes the clipboard text into text edit.-
515 \row \li Ctrl+X \li Deletes the selected text and copies it to the clipboard.-
516 \row \li Shift+Delete \li Deletes the selected text and copies it to the clipboard.-
517 \row \li Ctrl+Z \li Undoes the last operation.-
518 \row \li Ctrl+Y \li Redoes the last operation.-
519 \row \li Left \li Moves the cursor one character to the left.-
520 \row \li Ctrl+Left \li Moves the cursor one word to the left.-
521 \row \li Right \li Moves the cursor one character to the right.-
522 \row \li Ctrl+Right \li Moves the cursor one word to the right.-
523 \row \li Up \li Moves the cursor one line up.-
524 \row \li Down \li Moves the cursor one line down.-
525 \row \li PageUp \li Moves the cursor one page up.-
526 \row \li PageDown \li Moves the cursor one page down.-
527 \row \li Home \li Moves the cursor to the beginning of the line.-
528 \row \li Ctrl+Home \li Moves the cursor to the beginning of the text.-
529 \row \li End \li Moves the cursor to the end of the line.-
530 \row \li Ctrl+End \li Moves the cursor to the end of the text.-
531 \row \li Alt+Wheel \li Scrolls the page horizontally (the Wheel is the mouse wheel).-
532 \endtable-
533-
534 To select (mark) text hold down the Shift key whilst pressing one-
535 of the movement keystrokes, for example, \e{Shift+Right}-
536 will select the character to the right, and \e{Shift+Ctrl+Right} will select the word to the right, etc.-
