O Retina, Retina, wherefore art thou Retina?

Published December 8, 2015 by Geoff Perlman

eyeball.pngDuring my keynote address last April at XDC, the Xojo Developer Conference, I said that we would be adding Retina support (the OS X feature that provides for ultra-high resolution displays) to the OS X framework in the 4th quarter of this year. We have been working very hard on Retina support both for the OS X framework and for the IDE itself. We didn’t want to stop there though. Windows also supports ultra-high resolution displays. For Windows, this technology is called HiDPI. Xojo is a cross-platform tool so we decided we should support both Retina and HiDPI, and do it in such a way that you don’t have to do much of anything and they just work.

UPDATE: Xojo Retina is here, April 2016

Guest Post Tip: Formatted Text/Strings in Xojo

Writing long concatenated text in Xojo (or any programming language) tends to make the code difficult to read. Typically there is a block of code that has line extenders (_), a single line that goes on forever or a block of code that appends text to an existing variable. All are hard to read. And when you add SQL statements to the mix it can become difficult to easily see what you are trying to achieve.

I’€™ve started using Constants for this reason.

After months of work, your project is so fabulous that you need more developers. You’ve been using Git as your version control system and creating/merging branches to keep it all straight, but so far it’s just been for personal use. How do you coordinate with others to maintain some semblance of order?

Try the Gitflow Workflow.
