The 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.

The WebImageViewer control allow us to load and display any image retrieved from a given URL. Wouldn’t be nice to have that same kind of functionality in the Desktop and iOS versions of the ImageViewer? Continue reading and I’ll show you how to achieve just that.
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.
Sometimes we need to deal with temporary FolderItem instances, and in those cases it would be great to not have to care about when they get out of scope in order to delete them. Wouldn’t it be great to automate that task? Continue reading and you’ll see how easy it is to implement this!
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.
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.
Starting with Xojo 2018r1, your Xojo apps require the libunwind8 library to be installed on your Raspberry Pi. Here’s how to update your Pi.
In honor of Pi Day 2018, Xojo Pi licenses will be free! Xojo Pi licenses allow you to build console apps for Linux ARM for use with Raspberry Pi 2 and Raspberry Pi 3.
With the release of Xojo 2017 Release 2 we have updated our Linux Desktop framework to use GTK+ 3 instead of GTK+ 2. For those not familiar with Linux, GTK+ is a User Interface (i.e. UI) toolkit, much like Cocoa is for macOS and Win32 controls (or WinForms.NET or WPF) is for Windows. GTK+ 2 has been supplying the user interface for Xojo Desktop apps for Linux since we first targeted Linux over a decade ago. It has since been deprecated in favor of GTK+ 3 for quite some time now and GTK+ 2 is typically not installed by default on most Linux distros these days, which makes deploying Xojo Desktop apps on Linux more painful. Unfortunately GTK+ 3 is not ABI compatible with GTK+ 2 so we could not migrate to using GTK+ 3 without completely ditching GTK+ 2.
Let’s take a closer look at what this means for your Linux apps:
