Blog about the Xojo programming language and IDE
Geoff just wrapped up the keynote here in sunny, windy Miami, Florida.
After a brief introduction welcoming attendees from 11 different countries, Geoff began the keynote by sharing some graphs showing how the Xojo community has been changing.
Comments closedXojo includes a good amount of UI controls available from the Library for Desktop, Web, iOS and Raspberry Pi targets. These are the pieces that allow you to layout the user interface of your apps: properties, methods and events that, when combined, define the specific behavior of the project at hand.
Sometimes, subclassing the available controls is the answer to add specific behaviors you need. But what happen when none of the controls offer what you need, whether visually or functionally? The answer is the Canvas class (for Desktop projects), WebCanvas class (for Web projects) and iOSCanvas class for iPhone and iPad devices. But how do you create your own UI controls from scratch? Read on to learn…
Comments closedMost Xojo Cloud users have already switched to the newer Xojo Cloud servers. These new servers have more RAM and SSDs and are the priced lower or the same as our previous servers. But moving your projects from one server to another is easier said than done. You’ll need to plan carefully to avoid downtime. Here is a simple change you can make to your DNS settings in order to limit downtime, making the move to a better server smoother.
Comments closedCode doesn’t care whether you are new to programming or an old pro, a citizen developer or the head of engineering, some missteps can catch any of us. Read on to learn some of the most common programming pitfalls and how to avoid them.
Comments closedGitHub just announced that private repositories are now free. GitHub has been a great source for Xojo open-source projects, so being able to also use it for private repositories is a nice bonus.
Comments closedThere 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.
Comments closedXojo 2018 Release 4 updated SQLite to 3.25. The SQLite 3.25 release had two significant changes: Window Functions and an improved ALTER TABLE command.
Comments closedPrior 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.
Comments closedDeveloping for iOS with Xojo can be quick and easy, but if you need more power for your app’s controls, your options are:
If you don’t have the time or inclination for these options, Falco Software’s extensions could be what you are looking for. The extensions work similarly to Xojo, just drag the control and start developing. No alien objects to create, no extra code to maintain. Here are some examples of where Falco Software’s extensions can simplify and speed up your iOS development.
Comments closedIn a previous entry we started to dig into web services with Xojo. The first post focused on the backend (server side), creating the Xojo app acting as middleware between the clients and the database that holds your data. We are using SQLite as the backend engine but it would not be difficult to change to other supported database engines like PostgreSQL, MySQL (MariaDB), Oracle or SQL Server, and even ODBC; all of these are supported by Xojo!
