Because it is old Lessie stable release and will not install on later systems without tricking it out. Only stable is 37 and it is instaled by default if I am right. So with the latest webkit it is not working correctly. I guess could be a bug. I reported this before longer time but there is no fixing at all. Only 2020R1 works without complaining in install but makes later problems with the package management. This needs wo uninstall xojo package later. Given at 3 Ubuntu 20 Systems in my House.
I am working with the TGZ Archive, unpacked and started xojo directly from the directory with double click after making it executable. It works without problems and needs no installation and rund for 2020 and 2019r3.2 and 3.1 as far as I was testing. It is only than not installed but working on your computer and also licensing is working correctly.

Maybe but it is not working with Ubuntu V20 and it is known by xojo. They had no solution and I had to find a way to be able to work under linux. When the deb is working under debian linux it is okay but all of my users have ubuntu linux and I have wo work with it in this case cause we decided this detail long time before the decision for xojo.
The IDE will function normally as it was compiled previous to this change. Compiling from 2019R1.1 on Big Sur, however, results in this error due to changes in the OS in Big Sur. Specifically, the compiler is unable to locate the specified file during the linking step of the build process.
Note: There are different books for the older versions -- pre-Xojo 2019 r1.1, Jessie OS, and pre-Pi 3 B hardware. This book is for programing with the latest Raspberry Pi 4 B hardware, with the Buster OS, and API2 2019 r3.1 Xojo IDE with pigpio!
This ebook is a PDF document and all examples include Xojo code. This is one of many books which can be purchased at Xojo Library. More information is available at the author's website at: -program-raspberry-pi-4b-electronics-with-xojo-buster-edition
Prima release per il 2019 di questo ambiente di sviluppo. Moltissimi miglioramenti e nuove funzionalità in attesa delle novità che verranno presentate nella prossima XDC a Miami e alla conferenza di Colonia.
URLConnection - The new URLConnection class (which is part of API 2.0 but was added in Xojo 2019r1), replaces the HTTPSocket class and provides support for HTTP 1.1 and above. It also now relies on the underlying OS's implementation so as operating systems are updating, your apps that use URLConnection will automatically improve. Should the user have a proxy configured, your app will automatically take advantage of it.
Existing Projects - Transitioning to API 2.0 can be done at your leisure. Even though many of the functions your projects are using today are now deprecated, they won't be going away any time soon. The first step is to make sure your project runs as-is in 2019r2 prior to making any changes. If it does, then you are ready to transition to API 2.0.
Auto-Complete - The first place you will likely notice API 2.0 is when using Auto-Complete. Projects created in versions of Xojo prior to 2019r2 will still show methods, properties and other items that have been deprecated along with their API 2.0 replacements. Projects created in 2019r2 or later will not.
Paul Abell2019-05-30 (publication date) Visual Studio Basic and Xojo are remarkably similar... but just enough different that those subtle changes can throw you off your programming game. What you need is a guide, someone to show you the Xojo ropes.
Tom Baumgartner2019-06-09 (publication date) Writing your first REALbasic program that prints only from the Mac is both a blessing and a curse. It is a blessing because printing from the Mac works basically as you expect. It is a curse because, when you port the program to Windows, you find that printing is not...[Show More]
Jens Bendig2019-06-09 (publication date) Instead of making your simple app support complicated printing, why not use a pre-formatted template instead?At the REALbasic Developer Conference in Frankfurt at the end of 2008 at least two developers talked to me about how to generate print files. They seemed to think this was something like brewing magic...[Show More]

Craig Boyd2019-06-09 (publication date) In this article I intend to explain to you what a data model is and how to read one.Within the field of data modeling there are several kinds of models and in order to make sure we are all talking about the same thing I need to briefly lay out,...[Show More]
JC Cruz2019-06-09 (publication date) Image processing is a large group of algorithms that operate on data in a digitized image. Some enhance certain traits of the image; others measure parts of that image. Some transform the image into a different form; others filter out data from the image.Many of these algorithms have been used...[Show More]
JC Cruz2019-06-09 (publication date) Today we will learn the basics behind an image histogram.First, we study the concept of a histogram and how it relates to image data. We then explore two ways of modifying the histogram data.
JC Cruz2019-06-09 (publication date) Today we will study the concept of digital watermarks.First, we will learn how a watermark protects an image from unfair use. Then, we will look at three forms of watermark algorithms.
JC Cruz2019-06-09 (publication date) In this article you will learn the parts of an XML document. Then you will learn what makes up a valid document. Next, you will look at a handful of XML classes in REALbasic. You will then use these classes to create, query, and save a simple XML document.
JC Cruz2019-06-09 (publication date) Error handling is a must for any software product slated for public use. So in this article, we will explore how to detect and deal with code errors in a REALbasic project.We will learn how to package an error as an exception, and how to trap it at run time....[Show More]
Eugene Dakin2019-07-28 (updated) Originally Added: 2018-12-20 Xojo Windows Declare Version 3.2 has just been finished with more examples, more constants, more data, more explanations, updates from ANSI to Unicode, all Windows 10 compatible, both 32-bit and 64-bit compatible, and updated to Xojo 2018 r3.Xojo provides a RAD (Rapid Application Development) environment because it protects the user...[Show More]
Eugene Dakin2019-05-20 (publication date) There are many books that create console examples for Python, which is great to determine that the logic of a program works well. However, there is very little information on creating and controls and interact with forms and windows with Python 3. This is where this book is helpful.

Eugene Dakin2022-01-29 (updated) Originally Added: 2020-05-14 Xojo Windows Declare Version 4.2 has just been finished with updates to Xojo 2019 r3.1 that has implemented Xojo-API2.Xojo provides a RAD (Rapid Application Development) environment because it protects the user from the Operating System. Xojo has many helpful functions, and declares add to this existing toolbox.
Note: Microsoft Word has a 2016 version, and a 2019 version. Some of the functionality has changed with Microsoft when moving from 2016 to 2019, and this new book has the updated API2 code along with being compatible with the newer Microsoft Word 2019 version. Some of the code for this book will not work with Microsoft 2016 because of some of the changes that Microsoft did to the program.

Tam Hanna2019-06-09 (publication date) The idea of Extreme Programming (from now on we will use the common abbreviation XP) was created by an individual named Kent Beck. His core idea was later refined in the group of so-called agile processes.They can be summed up as following:*Individuals and interactions over processes and tools
Mike Titlebaum2019-06-09 (publication date) Databases (and programming in general) are used to solve business problems. In order to learn about how to use a relational database, let's try to solve a sample business problem we've been presented with. We will soon see why we need to use a relational database rather than a simple...[Show More]
Marc Zeedar2019-06-09 (publication date) Picture Packer is designed to solve four key problems with managing graphics with REALbasic:It supports transparency so you no longer need a separate mask file for each graphic.
Marc Zeedar2019-06-09 (publication date) Lately I've created several projects where the main application is little more than a run-time engine and the core work is done via RBScripts. Why use such an architecture? The main benefit is flexibility. By not building the core into the app itself, I am free to modify the core at any time. 2ff7e9595c
