| 346 | \class QTextEdit | - | ||||||
| 347 | \brief The QTextEdit class provides a widget that is used to edit and display | - | ||||||
| 348 | both plain and rich text. | - | ||||||

| 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. | - | ||||||
| 502 | - | |||||||
| 503 | \section2 Editing Key Bindings | - | ||||||
| 504 | - | |||||||
| 505 | The list of key bindings which are implemented for editing: | - | ||||||
| 506 | \table | - | ||||||
| 507 | \header \li Keypresses \li Action | - | ||||||
| 508 | \row \li Backspace \li Deletes the character to the left of the cursor. | - | ||||||
| 509 | \row \li Delete \li Deletes the character to the right of the cursor. | - | ||||||
| 510 | \row \li Ctrl+C \li Copy the selected text to the clipboard. | - | ||||||
| 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. | - | ||||||
