Loading 3rd Party Frameworks in Xojo iOS

Published January 17, 2019 by Greg O'Lone

Did you know that it’s possible to load and use 3rd Party Frameworks in your Xojo iOS projects? There’s quite a number of good projects out there, many of which are on sites like GitHub and freely available for use in your projects. If you’re familiar with Declares in iOS, loading a 3rd Party framework requires just a couple of extra lines of code and a CopyFilesStep.

Last year at XDC 2018, Jérémie Leroy talked about making sure your screenshots mimicked the Apple method so that the date was always Jun 9th, the time was always 9:41 AM, the battery always shows as full and the WiFi strength always shows full. It got me thinking that it might be handy to be able to make the simulator always show those values when you do a debug run so that you don’t need to think about it when you are ready to start taking screenshots and movies of your app. One way to do that is to build & run project like SimulatorStatusMagic on the simulator before running your project, but it would be more useful if it was automatic.

Low-Code Doesn’t Mean No Control

Published December 20, 2018 by Geoff Perlman

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.

Animating the Web: Fading Images in-out

Published December 19, 2018 by Javier Menendez

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.

Updating Code That Used The Graphics Property

Published December 6, 2018 by Paul Lefebvre

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.

Hour of Code: Xojo Dojo

Published November 29, 2018 by Paul Lefebvre

December 3rd kicks off Computer Science Education Week 2018! Computer Science Education Week is held in early December every year in recognition of the birthday of computing pioneer Admiral Grace Hopper. Alongside this is the Hour of Code promotion where schools throughout the world get students to try at least 1 hour of programming at some point during the week.

Each year for Hour of Code, I volunteer at the local Middle School to talk to the students about what it is like to be a programmer and do a little bit of programming. This year I plan to demonstrate Xojo Dojo with a Raspberry Pi and show the kids how much fun coding and Xojo programming can be.
