JavaFX Text Icons as Images & Files

There are plenty of high-quality icon fonts for scalable user interfaces, and drawing them directly as Text into JavaFX UIs is simple. But what if you need the icon as an Image or a disk file? That’s not hard to achieve, either, but there are some non-obvious steps and many Java APIs to navigate. So … Continue reading “JavaFX Text Icons as Images & Files”

JavaFX ListView Sizing

JavaFX supports automatic self-adjusting layout that resizes controls along with the containing window, but this may require some non-obvious changes to the controls’ default properties. The problem I recently ran into was automatically resizing a ListView within a VBox.

WinRT vs C# Overload Resolution

Browsing the Application Compatibility notes for the new .NET Framework 4.5, I noticed a very odd entry concerning Math.Ceiling and Math.Floor: Change: When you use .NET for Windows Store apps, C# may have difficulty with overload resolution when the Math.Ceiling or Math.Floor method is passed an integer. Impact: Source code may not compile successfully, or … Continue reading “WinRT vs C# Overload Resolution”
