There are low-code platforms that don’t provide ability to call directly into the operating system. Fortunately, Xojo does. Our vision for Xojo has always been to make the tool easy to learn and highly productive to develop applications, without sacrificing power when you need it.

This tutorial will show you how easy it is to create animations on components of Xojo web apps, thanks to the use of the Style Editor and the WebAnimator class. Learn how to do a fade effect between two images that you can expand and adapt to your web apps.
In order to recreate this fade effect we’ll mainly use a couple of styles (WebStyle class) to set the initial status for each one of our images (instances from the WebImageView class). These will be overlaped in the web page, sharing the same position. Then we’ll add a button to the web page so it will fire the animation every time it is clicked.
Xojo 2018 Release 4 updated SQLite to 3.25. The SQLite 3.25 release had two significant changes: Window Functions and an improved ALTER TABLE command.
When I ask “What kind of variable are you?” I don’t mean “Are you an Integer, a String, a Variant, an Object?”. I am asking “are you a value type or a reference type?”. What’s the difference between the two?
Prior to Xojo 2018r3 Window and Canvas both had a Graphics property that you could access and draw to. This was deprecated in 2011 because it had significant performance issues on all platforms. The preferred way to draw your graphics since 2011 has been to use the Window.Paint or Canvas.Paint event handlers and the supplied parameter g As Graphics.
Starting with Xojo 2018r3, this Graphics property was removed from Window and Canvas so if you had code that was still relying on it, that code will no longer compile. Here are some tips on how you can migrate your code to use the Paint event handlers and tell the Canvas to update with a call to Invalidate.
To help developers check if their software is ready for 64-bit, Apple added a new tool for developers in Xcode 9. With this tool, you can force macOS to run as “64-bit only” to see if your software is ready for a 64-bit only environment.
