Comments closedThe Bug Bash was good at bringing back to our attention some older bugs. One such issue was multi-monitor support with mixed scale factors on Windows. While supporting 2 monitors at different scale factors worked for the most part, anything beyond that was flawed.
Comments closedStarting with Xojo 2022r3 it is possible to create and add tables to PDF documents using Xojo’s PDFTable class and the PDFTableDataSource class interface. Among…
Comments closedIn September we hosted The Xojo Developer Retreat in Nashville and it was a huge success! From exciting educational sessions, to an exploration of the Xojo product roadmap, to informative presentations from Xojo Engineers about how Xojo is made and the Xojo framework, there was a lot to take in! If you missed any of the announcements that were shared, you can watch Founder and CEO Geoff Perlman’s Conference Keynote free on YouTube. The rest of the session videos are available for purchase here.
Comments closedXojo 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 closedXojo MVP Anthony Cyphers has been using Xojo for nearly 20 years and is currently building a User Interface framework for a project he is working on. This project needs to have the ability to tweak colors as needed and have those changes applied across every element of that framework. Read on Anthony’s blog about the way he solved this problem.
Comments closedI was recently asked if there was a way to use Xojo Canvas Graphics to draw using the math X-Y coordinate system. First a little background. In Xojo (along with Java, .NET and many other languages), graphics are drawn where (0,0) is at the top left, X increases to the right and Y increases down. Other languages or APIs (Cocoa, for example) use a system where (0,0) is at the bottom left, X increases to the right and Y increases up.
Comments closedSometimes we need to rotate a Picture from portrait to landscape and vice versa. Since the introduction of the Graphics methods Translate and Rotate this is pretty simple to do! Continue reading and I will show you how to create a Method Extension for the Picture class that will be able to do that. This will work on Desktop and iOS projects by only copying and pasting the code, but you will need to make some changes to the example project for the Web version because of the need to convert Picture to WebPicture and back.
