Different -characters can be used to enumerate items, and we can use both Roman and Arabic -numerals in the same list structure: - -1. Introduction -2. Qt Tools - 1) Qt Assistant - 2) Qt Designer - 1. Form Editor - 2. Component Architecture - 3) Qt Linguist - -The list will automatically be renumbered if you add or remove items. *Try -adding new sections to the above list or removing existing item to see the -numbers change.* - -Task lists can be used to track progress on projects: - -- [ ] This is not yet done -- This is just a bullet point -- [x] This is done - -## Images - -Inline images are treated like ordinary ranges of characters in the text -editor, so they flow with the surrounding text. Images can also be selected in -the same way as text, making it easy to cut, copy, and paste them. - - *Try to select this image by clicking and -dragging over it with the mouse, or use the text cursor to select it by holding -down Shift and using the arrow keys. You can then cut or copy it, and paste it -into different parts of this document.* - -## Tables - -QTextEdit can arrange and format tables, supporting features such as row and -column spans, text formatting within cells, and size constraints for columns. - -| | Development Tools | Programming Techniques | Graphical User Interfaces | -| ------------: | ----------------- | ---------------------- | ------------------------- | -| 9:00 - 11:00 | Introduction to Qt ||| -| 11:00 - 13:00 | Using qmake | Object-oriented Programming | Layouts in Qt | -| 13:00 - 15:00 | Qt Designer Tutorial | Extreme Programming | Writing Custom Styles | -| 15:00 - 17:00 | Qt Linguist and Internationalization | | | - -*Try adding text to the cells in the table and experiment with the alignment of -the paragraphs.* - -## Hyperlinks - -QTextEdit is designed to support hyperlinks between documents, and this feature -is used extensively in -[Qt Assistant](http://doc.qt.io/qt-5/qtassistant-index.html). Hyperlinks are -automatically created when an HTML file is imported into an editor. Since the -rich text framework supports hyperlinks natively, they can also be created -programatically. - -## Undo and Redo - -Full support for undo and redo operations is built into QTextEdit and the -underlying rich text framework. Operations on a document can be packaged -together to make editing a more comfortable experience for the user. - -*Try making changes to this document and press `Ctrl+Z` to undo them. You can -always recover the original contents of the document.* - diff --git a/examples/widgets/richtext/textedit/images/logo32.png b/examples/widgets/richtext/textedit/images/logo32.png Binary files
