RTEdit 2.0 is out! The most powerful rich text control for Xojo

Sveinn_Runar_Sigurdsson · July 19, 2025, 5:24pm

RTEdit has been updated to version 2.0.

This major release represents several hundred hours of development to reach this milestone. RTEdit now includes every module maintained by the Quill 2.0 community and significantly modifies both Quill and its modules at the JavaScript layer to ensure an optimal user experience and a seamless workflow on macOS and Windows desktops.

To get started, simply add the RTEdit class (960kb) to your project (no plugins or dependencies required) and customize it to your needs within the IDE, in the control’s opening event, or both. For a GitHub download link, scroll to the bottom of the page. RTEdit 2.0 is compatible with Windows and Mac desktop projects written in XOJO versions 2024 or newer.

What’s New

Brand new demo project, including 5 new demos, tutorials, and comprehensive documentation.
Support for custom labels and tooltips in table modals and overlays.
Ability to define a specific color for italic text via the ColorTextItalic property.
Improved initialization performance, dynamically adjusting based on the modules and formats included in each build.
Arrow keys can now be used to navigate between columns and rows when a table is selected.
Modules can now be included or excluded via the IDE interface (e.g., Variables, Tables, DragAndDrop, KeyboardBinding).
AllowMentions renamed to AllowVariables for consistency.
Added VariablesAt() property to define variables using the @ character.
getDocumentMentions renamed to getDocumentVariables for consistency.
ColorMention group renamed to ColorVariables.
ColorVariablesPopup renamed to ColorVariablesText for naming consistency.
Added multiple ColorVariables... properties to provide full control over the appearance and layout of the variables popup window, including scrollbar styling.
New color properties added for customizing the appearance of code blocks (ColorCodeBlock, ColorCodeBlockBackground).
ColorQuote renamed to ColorBlockQuote for consistency.
All primary color settings can now be edited directly from the IDE.
All five color schemes have been refined, with layout adjustments for variable popups.
Updated the default PlaceholderText value.
New BlockQuoteIndentation property introduced to control default indentation for block quotes.
Redesigned sandbox demo interface for improved usability, including runtime color editing and tooltips for every UI element.
Fixed a non-fatal error that occurred when AutoFormatLinks was set to False.
Fixed layout rendering issues in code blocks.
Updated the default color scheme for code blocks.
Added AllowVideo property (default: False) to support embedded video insertion. This is also configurable via the IDE.
Improved performance and consistency of ImportDocumentToJSON / ExportDocumentToJSON. A dedicated demo project has been created for these features.
RTEdit now includes several additional fonts by default.
The currently selected font and heading styles are now correctly reflected in the toolbar when using the Snow theme.
Fixed a bug where Xojo incorrectly inserted a JavaScript newline character into code blocks during JSON conversion.
New InsertVariable(VariableType, Value As String) method added for programmatic variable insertion.
Introduced ColorToolbarDisabled property to visually indicate disabled toolbar icons (e.g., when editing table cells, where not all styles are allowed).
Quickly create and export your own ColorScheme in real-time, using the sandbox demo.
Numerous bug fixes and quality-of-life improvements throughout.

This major release represents several hundred hours of development to reach this milestone. RTEdit now includes every module actively maintained by the Quill 2.0 community and significantly modifies both Quill and its modules at the JavaScript layer to ensure an optimal user experience and a seamless workflow on macOS and Windows desktops.

A big thanks to all the users who provided feedback, feature-requests and bug reports.

WOW! Thank you for sharing this fantastic piece of work. As I look through the code I see many ways that I can improve on the personal programs I am making. Thanks again, I cannot wait to get back to it tomorrow.
