Xojo has very good graphics support. You can drop images into your project and use them with several controls. You can use the various Paint events to draw your own graphics. And there’s another source of graphics you may not have considered: emojis. Emojis can be used anywhere that text can be used because they are simply Unicode characters. That means they can be used in textfields, buttons, labels, popup menus, listboxes and more.

Comments closedI know, I know, it’s not the usual thing to do when making presentations, but did you know that it is possible to create presentations using Xojo’s and PDF? If you’re interested in this little experiment, read on and I’ll show you how to do it using Xojo’s PDFDocument.
Comments closedThe DrawText method from the Graphics class offers a simple way to left-align text at the given X and Y coordinates, even applying a wrap value to wrap every line of the text block at the provided width value. Wouldn’t it be great to be able to do the same thing while aligning blocks of text to the right and center? Continue reading and I will show you a technique you can use as the starting point which you can fine-tune to your specific needs.

Did you love Visual Basic? A lot of us did, but it’s 2021 and technology is ever-changing. As you look at the modern alternatives, consider Xojo. For over 20 years, Xojo has been the spiritual successor to VB, a rapid, cross-platform programming language and integrated development environment (IDE). Often called “VB for the Mac”, Xojo is more powerful than VB6 and more approachable than VB.NET. Two factors that are increasingly important because modern coders are everywhere, not just in the technology department.

Wouldn’t it be great to automate that task? Continue reading and you’ll see how easy it is to implement this!
Comments closedDecember 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.

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.
