The selection can be copied to the clipboard with copy(), or cut to the clipboard with cut(). 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().
You can retrieve the object that corresponds with the user-visible cursor using the textCursor() method. Selection of text is handled by the QTextCursor class, which provides functionality for creating selections, retrieving the text contents or deleting selections. The current paragraph’s alignment is set with setAlignment(). The current char format’s attributes are set with setFontItalic(), setFontWeight(), setFontUnderline(), setFontFamily(), setFontPointSize(), setTextColor() and setCurrentFont(). Using QTextEdit as an Editor ¶Īll the information about using QTextEdit as a display widget also applies here. Zooming into HTML documents only works if the font-size is not set to a fixed size. 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. The find() function can be used to find and select a given string within the text. If you use word wrap to the widget’s width WidgetWidth, you can specify whether to break on whitespace or anywhere with setWordWrapMode(). 80 column) FixedColumnWidth with the pixels or columns specified with setLineWrapColumnOrWidth().
Call setLineWrapMode() to set a fixed pixel width FixedPixelWidth, or character column (e.g. The setLineWrapMode() function is used to specify the kind of line wrap you want, or NoWrap if you don’t want any wrapping. 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.īy default the text edit wraps words at whitespace to fit within the text edit widget. Text itself can be inserted using the QTextCursor class or using the convenience functions insertHtml(), insertPlainText(), append() or paste(). Markdown with some embedded HTML can be parsed, with the same limitations that setHtml() has but toMarkdown() only writes “pure” Markdown, without any embedded HTML. Text can also be set or replaced using setMarkdown(), and the same caveats apply: if you then call toMarkdown(), the text that is returned may be different, but the meaning is preserved as much as possible. The entire text can be deleted with clear(). 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 text can be set or replaced using setHtml() which deletes any existing text and replaces it with the text passed in the setHtml() call.
QTextEdit can display a large HTML subset, including tables and images. It can be changed through the viewport() ‘s cursor property. The shape of the mouse cursor on a QTextEdit is IBeamCursor by default. If you find the HTML support insufficient for your needs you may consider the use of Qt WebKit, which provides a full-featured web browser widget.

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 just need to display a small piece of rich text use QLabel. Rich text can be described using a subset of HTML 4 markup refer to the Supported HTML Subset page for more information. The text edit can load both plain text and rich text files. If the text is too large to view within the text edit’s viewport, scroll bars will appear. QTextEdit can display images, lists and tables. Each character within a paragraph has its own attributes, for example, font and color. Paragraphs are separated by hard line breaks. The words in the paragraph are aligned in accordance with the paragraph’s alignment. A document consists of zero or more paragraphs. By default when reading plain text, one newline signifies a paragraph. A paragraph is a formatted string which is word-wrapped to fit into the width of the widget. QTextEdit works on paragraphs and characters. It is optimized to handle large documents and to respond quickly to user input. QTextEdit is an advanced WYSIWYG viewer/editor supporting rich text formatting using HTML-style tags, or Markdown format. Def find (exp)ĭef moveCursor (operation)ĭef toMarkdown ()
