“Retina” is the name for high resolution screens on Mac and iOS devices while “HiDPI” is the Windows equivalent. For simplicity, I’ll use HiDPI (which really is the universal technical term) for the rest of this blog post. Now that we have HiDPI support in Xojo, if you app doesn’t use any pictures, you can simply open your project, click on Shared under Build Settings and turn on the “Supports Retina/HiDPI” option. That’s all you need to do to have a HiDPI version of your app!
Having said that, if you are creating or using pictures in your project, there may be a few adjustments you’ll need to make to your code. A little over a year ago the process of making sure we had all of the necessary graphics together to build a Retina/HiDPI IDE was added to my to-do list. While 95% of the icons created for the Xojo IDE in 2013 already existed, most of the graphics that made up the IDE itself did not, and the IDE itself needed a bit of an overhaul to get it ready for the big change, both in graphics and in code…
2 CommentsWhile Xojo doesn’t currently provide a direct way of recursively deleting a folder, there are various options that will allow you to do this:
1. Recursively iterate through all the folders, deleting each one. You can read about that at our Developer Site, this is the best cross-platform way.
2. Use the Shell to recursively delete a folder (i.e. “del /s” on Windows, or “rm -rf” on OS X and Linux)

Comments closedBy default the built-in Web Browser that is used on Windows to show web pages uses the Internet Explorer 7 rendering engine. Which means the Xojo HTMLViewer and the ActiveX WebBrowser controls also use this older rendering engine.
Comments closedUpdate Aug 2017: Starting with Xojo 2017 Release 2 your app icons are automatically included in 64-bit Windows apps without having to do the workarounds described in this post. Upgrade today! If you are still using older versions of Xojo, then these workarounds are still necessary.
