Follow this tutorial to learn how to create active (clickable) words in a text of a TextArea control using the OOP Delegate design pattern, which allows you to dynamically change how your app will react when the user clicks on any of these active words. Best of all, this is cross-platform, so you can use it for macOS, Windows and Linux deployments!
It’s the first week of the Just Code challenge so I’m starting with something pretty simple. This app lets you choose a color using the system color picker and then shows you the color values in hexadecimal (useful for programming, HTML and CSS), RGB (red, green, blue), HSV (hue, saturation,value) and CMY (cyan, magenta, yellow).
These days everyone has a great idea for an app. Maybe you have an idea that would save you time at work, or maybe you’ve been thinking of an app that would automate something you do at home. Not sure where to start? One of your first steps is choosing a development tool that is right for you and for your project.
Here are five questions to guide your decision:
The Xojo community is vibrant and active, with all kinds of clever, open-source software being created for iOS, desktop, web and Raspberry Pi. By my latest count, there are at least 80 open-source projects for Xojo on GitHub and other places!
It talks about how you could make a maze-like structure on a Commodore 64 with just this one line of code:
10 PRINT CHR$(205.5+RND(1)); : GOTO 10
The author then goes on to show you how you might do something similar using Python and pygame.
I love all things retro and this seemed like fun, so I thought I would whip up the same thing in Xojo.
In today’s world, the only way to be sure you are reaching all your potential customers is to target multiple platforms. But cross-platform development is crazy-hard, right? Perhaps, if you are using tools like Java, Qt, Delphi or Xamarin it certainly can be. But with Xojo, cross-platform apps are simple to create.
In fact, Xojo lets you easily cross-compile desktop apps for Windows, macOS, Linux and Raspberry Pi. Plus, you can use the same Xojo language to create web and iOS apps too (Android coming soon!).
If the deprecations and changes to the FileMaker platform have you searching for alternatives, Xojo is a solid place to start. FileMaker developers use Xojo for a variety of reasons, including lower cost, more powerful apps and native iOS apps.
Xojo is a powerful, full-featured development tool and as far as professional development tools go, Xojo is amazingly easy to use. For people with programming experience or those that want to learn, Xojo is a great choice for creating powerful apps to meet any business need – from cross-platform desktop apps, web apps, mobile and iOT apps.
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:
