Earlier this year ago I wrote a post about using the SF Font symbols on macOS Picture.SystemImage
in iOS apps. However that technique has some downsides. For one, the symbol glyphs are hardcoded, which means that it’s not possible to access the new symbols added to the SF Font by Apple. In addition, it isn’t possible to set the font weight and scale for the glyph. In this new post, I’ll show a more flexible way to work with these symbols on macOS 11+.
Like many Xojo developers, I often use virtual machines for testing. Over time the virtual machine disk files can get pretty large, even if you…
Comments closedMany times, when we create a desktop application which is doing huge processes, it happens that the responsiveness of our app can be interrupted for few seconds. As developers we need to avoid such scenarios because we want to keep the interaction between the user and the app constant while it’s in use. You have to imagine that our customer doesn’t have a developer’s mindset and will not wait more than 5 seconds if the app freezes. Threading is a great solution to these situations.

Perhaps the code you’re working on just won’t do what you want or maybe you’re having trouble understanding code plucked from the internet. Talk to the duck. The rubber duck, that is. The term “rubber ducking” or “rubber duck debugging” is a software development technique where you explain the problem you are having to a rubber duck (or appropriate substitute). Often the act of explaining the problem to someone else, even if that someone is not real, can help you figure it out. It might be like inspiration struck.

You only get that if you use native user interface controls. That’s why Xojo has always provided native user interface controls, high-level access to native system functionality and compiled to native code.

Comments closedI recently watched this video from Computerphile on YouTube (one of my favorite channels). It demonstrates a simple bit-shift operation can generate amazing random strings of numbers. I thought I’d quickly convert it to Xojo.
Comments closedALE is a tool which Xojo developers can use to write assembly language in their applications. It can be used just for fun, distribution in compiled apps, or as a learning tool to discover what Xojo and other languages must be doing underneath.
Comments closedIn Xojo 2021R2 binary enumerations were introduced. These Enums must be declared in a module and are treated by the compiler as a class. Learn to create an Enum for Days of the Week and demonstrate the use of that by creating a custom segmented button control.
