currentCharFormat(), QTextCursor::blockFormat()

Returns the value of the autoFormatting property.

This method 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.

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

Reimplemented from QFrame::changeEvent()

Deletes all the text in the text edit. Note that the undo/redo history is cleared by this method.

cut(), setPlainText(), setHtml()

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.

Reimplemented from QAbstractScrollArea::contextMenuEvent()

Copies any selected text to the clipboard.

See also

copyAvailable()

This signal is emitted when text is selected or deselected in the text edit. When text is selected this signal will be emitted with status 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.

See also

selectionChanged()

This method 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.

This method 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.

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 property holds whether the text edit accepts rich text insertions by the user.

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.

This property holds 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.

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

This property holds the underlying document of the text editor.

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.

This property holds the title of the document parsed from the text.

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

This property provides an HTML interface to the text of the text edit. By default for a new empty document this property contains text to describe an HTML 4.0 document with no body text.

See also

Supported HTML Subset, plainText

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.

See also

lineWrapMode

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.

See also

lineWrapColumnOrWidth

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 holds the editor placeholder text. 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.

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.

See also

html

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.

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.

This property holds the tab stop width in pixels. By default this property contains a value of 80 pixels.

Specifies how the widget should interact with user input. The default value depends on whether the QTextEdit is read-only or editable, and whether it is a QTextBrowser or not.

This property holds whether undo and redo are enabled. Users are only able to undo or redo actions if this property is true, and if there is an action that can be undone (or redone).

This property holds the mode QTextEdit will use when wrapping text by words. By default, this property is set to QTextOption::WrapAtWordBoundaryOrAnywhere.
