Detailed Description

The QTextEdit class provides a widget that is used to edit and display both plain and rich text.

Introduction and Concepts

QTextEdit is an advanced WYSIWYG viewer/editor supporting rich text formatting using HTML-style tags. 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.

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 NoWrap if you don't want any wrapping. Call setLineWrapMode() to set a fixed pixel width FixedPixelWidth, or character column (e.g. 80 column) FixedColumnWidth with the pixels or columns specified with setLineWrapColumnOrWidth(). If you use word wrap to the widget's width 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 for example it is often useful in a log viewer, then you can use QTextDocument's maximumBlockCount property for that.

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:

KeypressesAction

Up Moves one line up.

Down Moves one line down.

Left Moves one character to the left.

Right Moves one character to the right.

PageUp Moves one (viewport) page up.

PageDown Moves one (viewport) page down.

Home Moves to the beginning of the text.

End Moves to the end of the text.

Alt+Wheel Scrolls the page horizontally (the Wheel is the mouse wheel).

Ctrl+Wheel Zooms the text.

Ctrl+A Selects all text.

The text edit may be able to provide some meta-information. For example, the documentTitle() function will return the text from within HTML <title> tags.

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.

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:

bool TextEdit::canInsertFromMimeData( const QMimeData *source ) const

{

if (source->hasImage())

return true;

else

return QTextEdit::canInsertFromMimeData(source);

}

We add support for image MIME types by returning true. For all other MIME types, we use the default implementation.

void TextEdit::insertFromMimeData( const QMimeData *source )

{

if (source->hasImage())

{

QImage image = qvariant_cast<QImage>(source->imageData());

QTextCursor cursor = this->textCursor();

QTextDocument *document = this->document();

document->addResource(QTextDocument::ImageResource, QUrl("image"), image);

cursor.insertImage("image");

}

}

We unpack the image from the QVariant held by the MIME source and insert it into the document as a resource.

Editing Key Bindings

The list of key bindings which are implemented for editing:

KeypressesAction

Backspace Deletes the character to the left of the cursor.

Delete Deletes the character to the right of the cursor.

Ctrl+C Copy the selected text to the clipboard.

Ctrl+Insert Copy the selected text to the clipboard.

Ctrl+K Deletes to the end of the line.

Ctrl+V Pastes the clipboard text into text edit.

Shift+Insert Pastes the clipboard text into text edit.

Ctrl+X Deletes the selected text and copies it to the clipboard.

Shift+Delete Deletes the selected text and copies it to the clipboard.

Ctrl+Z Undoes the last operation.

Ctrl+Y Redoes the last operation.

Left Moves the cursor one character to the left.

Ctrl+Left Moves the cursor one word to the left.

Right Moves the cursor one character to the right.

Ctrl+Right Moves the cursor one word to the right.

Up Moves the cursor one line up.

Down Moves the cursor one line down.

PageUp Moves the cursor one page up.

PageDown Moves the cursor one page down.

Home Moves the cursor to the beginning of the line.

Ctrl+Home Moves the cursor to the beginning of the text.

End Moves the cursor to the end of the line.

Ctrl+End Moves the cursor to the end of the text.

Alt+Wheel Scrolls the page horizontally (the Wheel is the mouse wheel).

To select (mark) text hold down the Shift key whilst pressing one of the movement keystrokes, for example, Shift+Right will select the character to the right, and Shift+Ctrl+Right will select the word to the right, etc.

See also currentCharFormat() and QTextCursor::blockFormat().

new QTextEdit.AutoFormattingFlag QtGui.QTextEdit.autoFormatting

(

)

virtual bool QtGui.QTextEdit.CanInsertFromMimeData ( QMimeData  source )

protectedvirtual

This function returns true if the contents of the MIME data object, specified by source, can be decoded and inserted into the document. It is called for example when during a drag operation the mouse enters this widget and it is necessary to determine whether it is possible to accept the drag and drop operation.

Reimplement this function to enable drag and drop support for additional MIME types.

new bool QtGui.QTextEdit.CanPaste

(

)

Returns whether text can be pasted from the clipboard into the textedit.

This function was introduced in Qt 4.2.

new void QtGui.QTextEdit.Clear

(

)

Deletes all the text in the text edit.

Note that the undo/redo history is cleared by this function.

See also cut(), setPlainText(), and setHtml().

new void QtGui.QTextEdit.Copy

(

)

Copies any selected text to the clipboard.

See also copyAvailable().

virtual QMimeData QtGui.QTextEdit.CreateMimeDataFromSelection ( )

protectedvirtual

This function returns a new MIME data object to represent the contents of the text edit's current selection. It is called when the selection needs to be encapsulated into a new QMimeData object; for example, when a drag and drop operation is started, or when data is copyied to the clipboard.

If you reimplement this function, note that the ownership of the returned QMimeData object is passed to the caller. The selection can be retrieved by using the textCursor() function.

override void QtGui.QTextEdit.CreateProxy ( )

virtual

Reimplemented from QtGui.QAbstractScrollArea.

new QMenu QtGui.QTextEdit.CreateStandardContextMenu

(

)

This function creates the standard context menu which is shown when the user clicks on the text edit with the right mouse button. It is called from the default contextMenuEvent() handler. The popup menu's ownership is transferred to the caller.

We recommend that you use the createStandardContextMenu(QPoint) version instead which will enable the actions that are sensitive to where the user clicked.

new QMenu QtGui.QTextEdit.CreateStandardContextMenu

(

QPoint

position

)

This function creates the standard context menu which is shown when the user clicks on the text edit with the right mouse button. It is called from the default contextMenuEvent() handler and it takes the position of where the mouse click was. This can enable actions that are sensitive to the position where the user clicked. The popup menu's ownership is transferred to the caller.

This function was introduced in Qt 4.4.

new QTextCursor QtGui.QTextEdit.CursorForPosition

(

QPoint

pos

)

returns a QTextCursor at position pos (in viewport coordinates).

new QRect QtGui.QTextEdit.CursorRect

(

)

returns a rectangle (in viewport coordinates) that includes the cursor of the text edit.

new QRect QtGui.QTextEdit.CursorRect

(

QTextCursor

cursor

)

returns a rectangle (in viewport coordinates) that includes the cursor.

new void QtGui.QTextEdit.Cut

(

)

Copies the selected text to the clipboard and deletes it from the text edit.

If there is no selected text nothing happens.

See also copy() and paste().

new void QtGui.QTextEdit.Dispose

(

)

new void QtGui.QTextEdit.EnsureCursorVisible

(

)

Ensures that the cursor is visible by scrolling the text edit if necessary.

new bool QtGui.QTextEdit.Find	(	string	exp,
		QTextDocument.FindFlag	options = 0
	)

Finds the next occurrence of the string, exp, using the given options. Returns true if exp was found and changes the cursor to select the match; otherwise returns false.

override bool QtGui.QTextEdit.FocusNextPrevChild ( bool  next )

protectedvirtual

Reimplemented from QWidget::focusNextPrevChild().

Reimplemented from QtGui.QWidget.

override object QtGui.QTextEdit.InputMethodQuery ( Qt.InputMethodQuery  property )

virtual

Reimplemented from QWidget::inputMethodQuery().

Reimplemented from QtGui.QWidget.

virtual void QtGui.QTextEdit.InsertFromMimeData ( QMimeData  source )

protectedvirtual

This function inserts the contents of the MIME data object, specified by source, into the text edit at the current cursor position. It is called whenever text is inserted as the result of a clipboard paste operation, or when the text edit accepts data from a drag and drop operation.

Reimplement this function to enable drag and drop support for additional MIME types.

new void QtGui.QTextEdit.InsertHtml

(

string

text

)

Convenience slot that inserts text which is assumed to be of html formatting at the current cursor position.

It is equivalent to:

edit->textCursor().insertHtml(fragment);

Note: When using this function with a style sheet, the style sheet will only apply to the current block in the document. In order to apply a style sheet throughout a document, use QTextDocument::setDefaultStyleSheet() instead.

new void QtGui.QTextEdit.InsertPlainText

(

string

text

)

Convenience slot that inserts text at the current cursor position.

It is equivalent to

edit->textCursor().insertText(text);

virtual object QtGui.QTextEdit.LoadResource ( int  type, QUrl  name  )

virtual

Loads the resource specified by the given type and name.

This function is an extension of QTextDocument::loadResource().

See also QTextDocument::loadResource().

Reimplemented in QtGui.QTextBrowser.

new void QtGui.QTextEdit.MergeCurrentCharFormat

(

QTextCharFormat

modifier

)

Merges the properties specified in modifier into the current character format by calling QTextCursor::mergeCharFormat on the editor's cursor. If the editor has a selection then the properties of modifier are directly applied to the selection.

See also QTextCursor::mergeCharFormat().

new void QtGui.QTextEdit.MoveCursor	(	QTextCursor.MoveOperation	operation,
		QTextCursor.MoveMode	mode = QTextCursor.MoveMode.MoveAnchor
	)

Moves the cursor by performing the given operation.

If mode is QTextCursor::KeepAnchor, the cursor selects the text it moves over. This is the same effect that the user achieves when they hold down the Shift key and move the cursor with the cursor keys.

This function was introduced in Qt 4.2.

See also QTextCursor::movePosition().

override void QtGui.QTextEdit.OnChangeEvent ( QEvent  e )

protectedvirtual

Reimplemented from QWidget::changeEvent().

Reimplemented from QtGui.QFrame.

override void QtGui.QTextEdit.OnContextMenuEvent ( QContextMenuEvent  e )

protectedvirtual

Reimplemented from QWidget::contextMenuEvent().

Shows the standard context menu created with createStandardContextMenu().

If you do not want the text edit to have a context menu, you can set its contextMenuPolicy to Qt::NoContextMenu. If you want to customize the context menu, reimplement this function. If you want to extend the standard context menu, reimplement this function, call createStandardContextMenu() and extend the menu returned.

Information about the event is passed in the event object.

void MyTextEdit::contextMenuEvent(QContextMenuEvent *event)

{

QMenu *menu = createStandardContextMenu();

menu->addAction(tr("My Menu Item"));

//...

menu->exec(event->globalPos());

delete menu;

}

Reimplemented from QtGui.QAbstractScrollArea.

new void QtGui.QTextEdit.OnCopyAvailable ( bool  b )

new System.Collections.Generic.List<QTextEdit.ExtraSelection> QtGui.QTextEdit.ExtraSelections

getset

Returns previously set extra selections.

This function was introduced in Qt 4.2.

This function allows temporarily marking certain regions in the document with a given color, specified as selections. This can be useful for example in a programming editor to mark a whole line of text with a given background color to indicate the existence of a breakpoint.

This function was introduced in Qt 4.2.

new string QtGui.QTextEdit.FontFamily

getset

Returns the font family of the current format.

Sets the font family of the current format to fontFamily.

new bool QtGui.QTextEdit.FontItalic

getset

Returns true if the font of the current format is italic; otherwise returns false.

If italic is true, sets the current format to italic; otherwise sets the current format to non-italic.

new double QtGui.QTextEdit.FontPointSize

getset

Returns the point size of the font of the current format.

Sets the point size of the current format to s.

Note that if s is zero or negative, the behavior of this function is not defined.

new bool QtGui.QTextEdit.FontUnderline

getset

Returns true if the font of the current format is underlined; otherwise returns false.

If underline is true, sets the current format to underline; otherwise sets the current format to non-underline.

new int QtGui.QTextEdit.FontWeight

getset

Returns the font weight of the current format.

Sets the font weight of the current format to the given weight, where the value used is in the range defined by the QFont::Weight enum.

new string QtGui.QTextEdit.Html

getset

This property provides an HTML interface to the text of the text edit.

toHtml() returns the text of the text edit as html.

setHtml() changes the text of the text edit. Any previous text is removed and the undo/redo history is cleared. The input text is interpreted as rich text in html format.

Note: It is the responsibility of the caller to make sure that the text is correctly decoded when a QString containing HTML is created and passed to setHtml().

By default, for a newly-created, empty document, this property contains text to describe an HTML 4.0 document with no body text.

new int QtGui.QTextEdit.LineWrapColumnOrWidth

getset

This property holds the position (in pixels or columns depending on the wrap mode) where text will be wrapped.

If the wrap mode is FixedPixelWidth, the value is the number of pixels from the left edge of the text edit at which text should be wrapped. If the wrap mode is FixedColumnWidth, the value is the column number (in character columns) from the left edge of the text edit at which text should be wrapped.

By default, this property contains a value of 0.

new LineWrapMode QtGui.QTextEdit.lineWrapMode

getset

This property holds the line wrap mode.

The default mode is WidgetWidth which causes words to be wrapped at the right edge of the text edit. Wrapping occurs at whitespace, keeping whole words intact. If you want wrapping to occur within words use setWordWrapMode(). If you set a wrap mode of FixedPixelWidth or FixedColumnWidth you should also call setLineWrapColumnOrWidth() with the width you want.

new bool QtGui.QTextEdit.OverwriteMode

getset

This property holds whether text entered by the user will overwrite existing text.

As with many text editors, the text editor widget can be configured to insert or overwrite existing text with new text entered by the user.

If this property is true, existing text is overwritten, character-for-character by new text; otherwise, text is inserted at the cursor position, displacing existing text.

By default, this property is false (new text does not overwrite existing text).

This property was introduced in Qt 4.1.

new string QtGui.QTextEdit.PlainText

getset

This property gets and sets the text editor's contents as plain text. Previous contents are removed and undo/redo history is reset when the property is set.

If the text edit has another content type, it will not be replaced by plain text if you call toPlainText(). The only exception to this is the non-break space, nbsp;, that will be converted into standard space.

By default, for an editor with no contents, this property contains an empty string.

This property was introduced in Qt 4.3.

new bool QtGui.QTextEdit.ReadOnly

getset

This property holds whether the text edit is read-only.

In a read-only text edit the user can only navigate through the text and select text; modifying the text is not possible.

This property's default is false.

Slot<System.Boolean> QtGui.QTextEdit.RedoAvailable

addremove

This signal is emitted whenever redo operations become available (available is true) or unavailable (available is false).

Slot QtGui.QTextEdit.SelectionChanged

addremove

This signal is emitted whenever the selection changes.

See also copyAvailable().

new QMetaObject QtGui.QTextEdit.StaticMetaObject

staticget

new bool QtGui.QTextEdit.TabChangesFocus

getset

This property holds whether Tab changes focus or is accepted as input.

In some occasions text edits should not allow the user to input tabulators or change indentation using the Tab key, as this breaks the focus chain. The default is false.

new int QtGui.QTextEdit.TabStopWidth

getset

This property holds the tab stop width in pixels.

By default, this property contains a value of 80 pixels.

This property was introduced in Qt 4.1.

getset

Returns the text color of the current format.

Sets the text color of the current format to c.

new QTextCursor QtGui.QTextEdit.TextCursor

getset

Returns a copy of the QTextCursor that represents the currently visible cursor. Note that changes on the returned cursor do not affect QTextEdit's cursor; use setTextCursor() to update the visible cursor.
