Detailed Description#

Introduction and Concepts#

QPlainTextEdit is an advanced viewer/editor supporting plain text. It is optimized to handle large documents and to respond quickly to user input.

QPlainText uses very much the same technology and concepts as QTextEdit , but is optimized for plain text handling.

QPlainTextEdit 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. Paragraphs are separated by hard line breaks. Each character within a paragraph has its own attributes, for example, font and color.

The shape of the mouse cursor on a QPlainTextEdit is Qt::IBeamCursor by default. It can be changed through the viewport() ‘s cursor property.

Using QPlainTextEdit as a Display Widget#

The text is set or replaced using setPlainText() which deletes the existing text and replaces it with the text passed to setPlainText() .

Text can be inserted using the QTextCursor class or using the convenience functions insertPlainText() , appendPlainText() or paste() .

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, WidgetWidth or NoWrap if you don’t want any wrapping. 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 QPlainTextEdit , as it is for example useful in a log viewer, then you can use the maximumBlockCount property. The combination of setMaximumBlockCount() and appendPlainText() turns QPlainTextEdit into an efficient viewer for log text. The scrolling can be reduced with the centerOnScroll() property, making the log viewer even faster. Text can be formatted in a limited way, either using a syntax highlighter (see below), or by appending html-formatted text with appendHtml() . While QPlainTextEdit does not support complex rich text rendering with tables and floats, it does support limited paragraph-based formatting that you may need in a log viewer.

Read-only Key Bindings#

When QPlainTextEdit is used read-only the key bindings are limited to navigation, and text may only be selected with the mouse:

Keypresses

Action

Qt::UpArrow

Moves one line up.

Qt::DownArrow

Moves one line down.

Qt::LeftArrow

Moves one character to the left.

Qt::RightArrow

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.

Using QPlainTextEdit as an Editor#

All the information about using QPlainTextEdit as a display widget also applies here.

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 QPlainTextEdit just create one on a QTextCursor object and then make that cursor the visible cursor using setCursor() . 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() .

QPlainTextEdit 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.

Syntax Highlighting#

Just like QTextEdit , QPlainTextEdit works together with QSyntaxHighlighter.

Editing Key Bindings#

The list of key bindings which are implemented for editing:

Keypresses

Action

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.

LeftArrow

Moves the cursor one character to the left.

Ctrl+LeftArrow

Moves the cursor one word to the left.

RightArrow

Moves the cursor one character to the right.

Ctrl+RightArrow

Moves the cursor one word to the right.

UpArrow

Moves the cursor one line up.

Ctrl+UpArrow

Moves the cursor one word up.

DownArrow

Moves the cursor one line down.

Ctrl+Down Arrow

Moves the cursor one word 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).

Ctrl+Wheel

Zooms the text.

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

Differences to QTextEdit#

QPlainTextEdit is a thin class, implemented by using most of the technology that is behind QTextEdit and QTextDocument. Its performance benefits over QTextEdit stem mostly from using a different and simplified text layout called QPlainTextDocumentLayout on the text document (see QTextDocument::setDocumentLayout()). The plain text document layout does not support tables nor embedded frames, and replaces a pixel-exact height calculation with a line-by-line respectively paragraph-by-paragraph scrolling approach. This makes it possible to handle significantly larger documents, and still resize the editor with line wrap enabled in real time. It also makes for a fast log viewer (see setMaximumBlockCount() ).

Description

QPlainTextEdit.NoWrap

QPlainTextEdit.WidgetWidth

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property backgroundVisibleᅟ: bool#

This property holds whether the palette background is visible outside the document area.

If set to true, the plain text edit paints the palette background on the viewport area not covered by the text document. Otherwise, if set to false, it won’t. The feature makes it possible for the user to visually distinguish between the area of the document, painted with the base color of the palette, and the empty area not covered by any document.

The default is false.

Access functions:
property blockCountᅟ: int#

This property holds the number of text blocks in the document..

By default, in an empty document, this property contains a value of 1.

Access functions:
property centerOnScrollᅟ: bool#

This property holds whether the cursor should be centered on screen.

If set to true, the plain text edit scrolls the document vertically to make the cursor visible at the center of the viewport. This also allows the text edit to scroll below the end of the document. Otherwise, if set to false, the plain text edit scrolls the smallest amount possible to ensure the cursor is visible. The same algorithm is applied to any new line appended through appendPlainText() .

The default is false.

Access functions:
property cursorWidthᅟ: int#

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

Access functions:
property documentTitleᅟ: str#

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

By default, this property contains an empty string.

Access functions:
property lineWrapModeᅟ: QPlainTextEdit.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() .

Access functions:
property maximumBlockCountᅟ: int#

This property holds the limit for blocks in the document..

Specifies the maximum number of blocks the document may have. If there are more blocks in the document that specified with this property blocks are removed from the beginning of the document.

A negative or zero value specifies that the document may contain an unlimited amount of blocks.

The default value is 0.

Note that setting this property will apply the limit immediately to the document contents. Setting this property also disables the undo redo history.

Access functions:
property overwriteModeᅟ: bool#

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

As with many text editors, the plain 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).

Access functions:
property placeholderTextᅟ: str#

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.

See also

document()

Access functions:
property plainTextᅟ: str#

This property gets and sets the plain text editor’s contents. The previous contents are removed and undo/redo history is reset when this property is set. currentCharFormat() is also reset, unless textCursor() is already at the beginning of the document.

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

Access functions:
property readOnlyᅟ: bool#

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.

Access functions:
property tabChangesFocusᅟ: bool#

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.

Access functions:
property tabStopDistanceᅟ: float#

This property holds the tab stop distance in pixels.

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

Do not set a value less than the horizontalAdvance() of the QChar::VisualTabCharacter character, otherwise the tab-character will be drawn incompletely.

See also

defaultTextOption

Access functions:
property textInteractionFlagsᅟ: Combination of Qt.TextInteractionFlag#

Specifies how the label should interact with user input if it displays text.

If the flags contain either Qt::LinksAccessibleByKeyboard or Qt::TextSelectableByKeyboard then the focus policy is also automatically set to Qt::ClickFocus.

The default value depends on whether the QPlainTextEdit is read-only or editable.

Access functions:
property undoRedoEnabledᅟ: bool#

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).

By default, this property is true.

Access functions:
__init__(text[, parent=None])#
Parameters:

Constructs a QPlainTextEdit with parent parent. The text edit will display the plain text text.

canInsertFromMimeData(source)#
Parameters:

source – QMimeData

Return type:

bool

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.

canPaste()#
Return type:

bool

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

centerCursor()#

Scrolls the document in order to center the cursor vertically.

centerOnScroll()#
Return type:

Notes:

See also

cut() setPlainText()

contentOffset()#
Return type:

QPointF

Returns the content’s origin in viewport coordinates.

The origin of the content of a plain text edit is always the top left corner of the first visible text block. The content offset is different from (0,0) when the text has been scrolled horizontally, or when the first visible block has been scrolled partially off the screen, i.e. the visible text does not start with the first line of the first visible block, or when the first visible block is the very first block and the editor displays a margin.

copy()#

Copies any selected text to the clipboard.

See also

copyAvailable()

copyAvailable(b)#
Parameters:

b – bool

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()#
Return type:

QMimeData

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()#
Return type:

QMenu

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(position)
Parameters:

position – QPoint

Return type:

QMenu

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.

currentCharFormat()#
Return type:

QTextCharFormat

Returns the char format that is used when inserting new text.

cursorForPosition(pos)#

find(exp[, options=QTextDocument.FindFlags()])
Parameters:
Return type:

bool

This is an overloaded function.

Finds the next occurrence, matching the regular expression, exp, using the given options.

Returns true if a match was found and changes the cursor to select the match; otherwise returns false.

Warning

For historical reasons, the case sensitivity option set on exp is ignored. Instead, the options are used to determine if the search is case sensitive or not.

Parameters:

arg__1 – bool

This signal is emitted whenever the content of the document changes in a way that affects the modification state. If changed is true, the document has been modified; otherwise it is false.

For example, calling setModified(false) on a document and then inserting text causes the signal to get emitted. If you undo that operation, causing the document to return to its original unmodified state, the signal will get emitted again.

moveCursor(operation[, mode=QTextCursor.MoveAnchor])#
Parameters:

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.
