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 \l 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.

signal

This signal is emitted when text is selected or de-selected in the text edit.

When text is selected this signal will be emitted with yes set to true. If no text has been selected or if the selected text is de-selected this signal is emitted with yes set to false.

If yes is true then copy() can be used to copy the selection to the clipboard. If yes is false then copy() does nothing.

◆ createMimeDataFromSelection()

QMimeData * QTextEdit::createMimeDataFromSelection ( ) const

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 copied 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.

◆ createStandardContextMenu() [1/2]

QMenu * QTextEdit::createStandardContextMenu ( )

\reimp

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.

◆ createStandardContextMenu() [2/2]

QMenu * QTextEdit::createStandardContextMenu ( const QPoint & position )

Since: 4.4 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 in document coordinates 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.

Property Documentation

◆ acceptRichText

QTextEdit::acceptRichText

readwrite

whether the text edit accepts rich text insertions by the user

Since: 4.1

When this property is set to false text edit will accept only plain text input from the user. For example through clipboard or drag and drop.

This property's default is true.

Definition at line 47 of file qtextedit.h.

◆ autoFormatting

QTextEdit::autoFormatting

readwrite

the enabled set of auto formatting features

The value can be any combination of the values in the AutoFormattingFlag enum. The default is AutoNone. Choose AutoAll to enable all automatic formatting.

Currently, the only automatic formatting feature provided is AutoBulletList; future versions of Qt may offer more.

Definition at line 30 of file qtextedit.h.

◆ cursorWidth

QTextEdit::cursorWidth

readwrite

Since: 4.2

This property specifies the width of the cursor in pixels. The default value is 1.

Definition at line 48 of file qtextedit.h.

◆ document

QTextEdit::document

readwrite

the underlying document of the text editor.

Note: The editor {does not take ownership of the document} unless it is the document's parent object. The parent object of the provided document remains the owner of the object. If the previously assigned document is a child of the editor then it will be deleted.

◆ documentTitle

QTextEdit::documentTitle

readwrite

the title of the document parsed from the text.

By default, for a newly-created, empty document, this property contains an empty string.

Definition at line 32 of file qtextedit.h.

Referenced by QTextBrowser::doSetSource().

◆ html

QTextEdit::html

readwrite

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. currentCharFormat() is also reset, unless textCursor() is already at the beginning of the document.

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.

See also: {Supported HTML Subset}, plainText

Definition at line 42 of file qtextedit.h.

◆ lineWrapColumnOrWidth

QTextEdit::lineWrapColumnOrWidth

readwrite

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.

See also: lineWrapMode

Definition at line 36 of file qtextedit.h.

◆ lineWrapMode

QTextEdit::lineWrapMode

readwrite

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.

See also: lineWrapColumnOrWidth

Definition at line 34 of file qtextedit.h.

◆ overwriteMode

QTextEdit::overwriteMode

readwrite

whether text entered by the user will overwrite existing text

Since: 4.1

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).

Definition at line 45 of file qtextedit.h.

◆ placeholderText

QTextEdit::placeholderText

readwrite

the editor placeholder text

Since: 5.2

Setting this property makes the editor display a grayed-out placeholder text as long as the document() is empty.

By default, this property contains an empty string.

See also: document()

Definition at line 52 of file qtextedit.h.

Referenced by setPlaceholderText().

◆ plainText

QTextEdit::plainText

readwrite

the text editor's contents as plain text.

Since: 4.3

Previous contents are removed and undo/redo history is reset when the property is set. currentCharFormat() is also reset, unless textCursor() is already at the beginning of the document.

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.

See also: html

Definition at line 44 of file qtextedit.h.

◆ readOnly

QTextEdit::readOnly

readwrite

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.

Definition at line 37 of file qtextedit.h.

◆ tabChangesFocus

QTextEdit::tabChangesFocus

readwrite

whether \uicontrol 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 \uicontrol Tab key, as this breaks the focus chain. The default is false.
