It’s early days but an Android milestone has been reached! We just recently crossed a milestone in our efforts – and now have code from the Xojo compiler running on both the simulator and real Android hardware.

Developing for iOS with Xojo can be quick and easy, but if you need more power for your app’s controls, your options are:
- study the Apple documentation, which can take time and building the right declares from scratch is not trivial; or
- use one of the many open source projects, though you may end up having to import things that you don’t want or need;
If you don’t have the time or inclination for these options, Falco Software’s extensions could be what you are looking for. The extensions work similarly to Xojo, just drag the control and start developing. No alien objects to create, no extra code to maintain. Here are some examples of where Falco Software’s extensions can simplify and speed up your iOS development.

In a previous entry we started to dig into web services with Xojo. The first post focused on the backend (server side), creating the Xojo app acting as middleware between the clients and the database that holds your data. We are using SQLite as the backend engine but it would not be difficult to change to other supported database engines like PostgreSQL, MySQL (MariaDB), Oracle or SQL Server, and even ODBC; all of these are supported by Xojo!
Comments closedI started learning how to code as a teenager. Back then there weren’t very many programming languages. I remember BASIC, Pascal, Fortran, COBOL, C and a handful of others that were highly specialized. Why so few? Because in the 1970’s, computers just couldn’t do very much compared to today. The available languages were sufficient for the limited tasks computers had been assigned to manage.
Over the last several decades, computer technology has exploded. The smartphone I carry around in my pocket is far more powerful than the fastest computers of my youth. As a teenager, I rarely encountered anything where a computer had played a part. Today the rare encounter would be with things where computers had played no part. Computers handle so many tasks now that, as a natural consequence, there are thousands of programming languages with more appearing every year.
With so many languages, it can be difficult to choose one. What is important in a programming language?
Comments closedThe Canvas control is a great way to draw pretty much anything to a window. With a Canvas, do all your drawing in its Paint event handler for the best quality and performance.
I’ve had many people ask for an example for how to create a Canvas that allows you to:
- Draw pictures within it (as objects)
- Move these objects
- Remove them
- Add labels to them
- Programmatically select one
This example demonstrates how to do all these things. It has a large Canvas on the window with several buttons that let you add and manage the objects on the Canvas.
Comments closedWith the availability of Xojo 2018 Release 3, Xojo now supports macOS Mojave’s new dark mode. This means you can update your own apps to support dark mode and it also means that the Xojo IDE works in dark mode.
Comments closedAbout three years ago, we added HiDPI/Retina support to our framework which was released to users as part of Xojo 2016r1 when we also shipped our first HiDPI IDE.
With Apple’s announcements at WWDC 2018 and the introduction of dark mode it was time to revisit our graphics and the overall appearance of the IDE again. Here are some things which contribute to the changes that have been made and ones that you will see in the coming months.
Comments closedThe WebCanvas control is used for drawing graphics in web apps. It takes advantage of the HTML5 Canvas making it fast and powerful. Sometimes is can be useful to be able to save the graphics drawn in the WebCanvas to an image file, but unfortunately there is no built-in Xojo method to do this.
However, by using a little JavaScript you can easily add this capability to Xojo.

Using Xojo Web to create complete web apps and solutions means not having to learn a bunch of interpreted languages and dozens of ever-changing frameworks. I’m looking at you: HTML, CSS (is that even a language?), JavaScript, PHP, et al. Of course, Xojo Web not only makes it possible to create your own web apps, but it also acts as the perfect middleware that your desktop and iOS apps can communicate with. Learn about APIs and web services with Xojo in the tutorial blog post.

For #JustCode week 11, I’ve finished a project I’ve been working on for several months. This project is a simple app that you can use to write and run your own scripts using Xojo code on the Raspberry Pi. I call it Xojo Dojo.
