Detailed Description

The PySide2.QtWidgets.QPlainTextEdit class provides a widget that is used to edit and display plain text.

Introduction and Concepts

PySide2.QtWidgets.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 PySide2.QtWidgets.QTextEdit , but is optimized for plain text handling.

PySide2.QtWidgets.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 PySide2.QtWidgets.QPlainTextEdit is Qt.IBeamCursor by default. It can be changed through the PySide2.QtWidgets.QAbstractScrollArea.viewport() ‘s cursor property.

Using QPlainTextEdit as a Display Widget

The text is set or replaced using PySide2.QtWidgets.QPlainTextEdit.setPlainText() which deletes the existing text and replaces it with the text passed to PySide2.QtWidgets.QPlainTextEdit.setPlainText() .

Text can be inserted using the PySide2.QtGui.QTextCursor class or using the convenience functions PySide2.QtWidgets.QPlainTextEdit.insertPlainText() , PySide2.QtWidgets.QPlainTextEdit.appendPlainText() or PySide2.QtWidgets.QPlainTextEdit.paste() .

By default, the text edit wraps words at whitespace to fit within the text edit widget. The PySide2.QtWidgets.QPlainTextEdit.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 PySide2.QtWidgets.QPlainTextEdit.setWordWrapMode() .

The PySide2.QtWidgets.QPlainTextEdit.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 PySide2.QtWidgets.QPlainTextEdit , as it is for example useful in a log viewer, then you can use the PySide2.QtWidgets.QPlainTextEdit.maximumBlockCount() property. The combination of PySide2.QtWidgets.QPlainTextEdit.setMaximumBlockCount() and PySide2.QtWidgets.QPlainTextEdit.appendPlainText() turns PySide2.QtWidgets.QPlainTextEdit into an efficient viewer for log text. The scrolling can be reduced with the PySide2.QtWidgets.QPlainTextEdit.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 PySide2.QtWidgets.QPlainTextEdit.appendHtml() . While PySide2.QtWidgets.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 PySide2.QtWidgets.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 PySide2.QtWidgets.QPlainTextEdit as a display widget also applies here.

Selection of text is handled by the PySide2.QtGui.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 PySide2.QtWidgets.QPlainTextEdit.textCursor() method. If you want to set a selection in PySide2.QtWidgets.QPlainTextEdit just create one on a PySide2.QtGui.QTextCursor object and then make that cursor the visible cursor using PySide2.QtWidgets.QWidget.setCursor() . The selection can be copied to the clipboard with PySide2.QtWidgets.QPlainTextEdit.copy() , or cut to the clipboard with PySide2.QtWidgets.QPlainTextEdit.cut() . The entire text can be selected using PySide2.QtWidgets.QPlainTextEdit.selectAll() .

PySide2.QtWidgets.QPlainTextEdit holds a PySide2.QtGui.QTextDocument object which can be retrieved using the PySide2.QtWidgets.QPlainTextEdit.document() method. You can also set your own document object using PySide2.QtWidgets.QPlainTextEdit.setDocument() . PySide2.QtGui.QTextDocument emits a PySide2.QtWidgets.QPlainTextEdit.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.

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

PySide2.QtWidgets.QPlainTextEdit is a thin class, implemented by using most of the technology that is behind PySide2.QtWidgets.QTextEdit and PySide2.QtGui.QTextDocument . Its performance benefits over PySide2.QtWidgets.QTextEdit stem mostly from using a different and simplified text layout called PySide2.QtWidgets.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 PySide2.QtWidgets.QPlainTextEdit.setMaximumBlockCount() ).

Parameters:newBlockCountPySide2.QtCore.int
PySide2.QtWidgets.QPlainTextEdit.canInsertFromMimeData(source)
Parameters:sourcePySide2.QtCore.QMimeData
Return type:PySide2.QtCore.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.

PySide2.QtWidgets.QPlainTextEdit.canPaste()
Return type:PySide2.QtCore.bool

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

PySide2.QtWidgets.QPlainTextEdit.centerCursor()

Scrolls the document in order to center the cursor vertically.

PySide2.QtWidgets.QPlainTextEdit.centerOnScroll()
Return type:PySide2.QtCore.bool
PySide2.QtWidgets.QPlainTextEdit.clear()

Deletes all the text in the text edit.

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

PySide2.QtWidgets.QPlainTextEdit.contentOffset()
Return type:PySide2.QtCore.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.

PySide2.QtWidgets.QPlainTextEdit.copy()

Copies any selected text to the clipboard.

PySide2.QtWidgets.QPlainTextEdit.copyAvailable(b)
Parameters:bPySide2.QtCore.bool
PySide2.QtWidgets.QPlainTextEdit.createMimeDataFromSelection()
Return type:PySide2.QtCore.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 PySide2.QtCore.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 PySide2.QtCore.QMimeData object is passed to the caller. The selection can be retrieved by using the PySide2.QtWidgets.QPlainTextEdit.textCursor() function.

PySide2.QtWidgets.QPlainTextEdit.createStandardContextMenu(position)
Parameters:positionPySide2.QtCore.QPoint
Return type:PySide2.QtWidgets.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 PySide2.QtWidgets.QPlainTextEdit.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.

PySide2.QtWidgets.QPlainTextEdit.createStandardContextMenu()
Return type:PySide2.QtWidgets.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 PySide2.QtWidgets.QPlainTextEdit.contextMenuEvent() handler. The popup menu’s ownership is transferred to the caller.

We recommend that you use the ( PySide2.QtCore.QPoint ) version instead which will enable the actions that are sensitive to where the user clicked.

PySide2.QtWidgets.QPlainTextEdit.currentCharFormat()
Return type:PySide2.QtGui.QTextCharFormat

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

PySide2.QtWidgets.QPlainTextEdit.cursorForPosition(pos)
