Uniform Type Identifiers (UTIs) are one of the many often misunderstood parts of building native macOS apps. While they’re not just for specifying file types, that’s what I’m going to focus on today.
Comments closedEver wonder how to conditionally implement newer features in your code while keeping the ability to use older versions of Xojo at the same time?…
Comments closedWinRT is an application framework meant as a replacement for the decades old Win32 API (at least the non-GUI parts of it). Because WinRT is COM-based, and entirely unmanaged code, accessing it directly from Xojo is possible.

Xojo includes a good amount of UI controls available from the Library for Desktop, Web, iOS and Raspberry Pi targets. These are the pieces that allow you to layout the user interface of your apps: properties, methods and events that, when combined, define the specific behavior of the project at hand.
Sometimes, subclassing the available controls is the answer to add specific behaviors you need. But what happen when none of the controls offer what you need, whether visually or functionally? The answer is the Canvas class (for Desktop projects), WebCanvas class (for Web projects) and iOSCanvas class for iPhone and iPad devices. But how do you create your own UI controls from scratch? Read on to learn…
Comments closedFor more years than I’d like to admit, the Layout Editor has been slow in terms of dragging controls around. As you add more controls, it gets worse. For web layouts, it’s been even worse. That’s primarily because we have to draw everything for a web layout whereas for a desktop layout, the OS draws the controls for us.
In an engineering meeting, I mentioned a discussion I had with a user about the speed of the Layout Editor and Travis said he had recently been reminded of how slow it was too. While most of the time issues in Xojo are carefully calculated and prioritized for maximum bang for the buck (as we say around here), that’s not always how it happens. After the meeting, Travis decided to dive into the Layout Editor code and see what could be done to speed it up.
The results are pretty remarkable.
