“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 CommentsYou don’t need to hook up your Pi to a physical display, keyboard and mouse. You can set up VNC on the Pi so you can remotely connect to it.
My Raspberry Pi 2 sits on my desk next to one of my speakers. It’s not hooked up to any display. I use a combination of SSH, SFTP and VNC when I need to work with it.
Comments closedOn Monday February 29th, the Raspberry Pi Foundation announced the new Raspberry Pi 3. This updated Pi has some significant improvements over the Pi 2, including:
- A 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU (~10x the performance of Raspberry Pi 1)
- Integrated 802.11n wireless LAN and Bluetooth 4.1
- Complete compatibility with Raspberry Pi 1 and 2
That last bullet point is notable because it means that Xojo is also fully compatible with the new Raspberry Pi 3!
Comments closedMost of us build apps without thinking too much about how much memory the app will need. Sure sometimes you end up creating an app that is a real memory buster but that’s unusual. With virtual memory, gone are the days when your app would just run out of memory and crash, or are they?
Comments closedWhile 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)
Windows specific ways:
3. SHFileOperation (an older API)
4. IFileOperation (the more modern API that Windows recommends over option #3)
I’ve decided to look at option #4, since this allows more customized options, like the ability to show a progress dialog. However, it is also the slightly more complicated option since it deals with COM & Delegates. The example illustrates this:
Comments closedA couple years ago I wrote a post about Going Rogue with Xojo. It proved to be rather popular and I got some great stories back from how people were able to use Xojo in their organizations.
