Rendering and vector graphics

The Fyne widgets (much like those in the Nuklear library in Chapter 9, nk – Nuklear for Go) are made up of simple graphical objects that the render drivers are responsible for drawing. The driver is included as part of the package, and so no additional setup is required to start an application. Similar to the Shiny toolkit (that we explored in Chapter 8, Shiny – Experimental Go GUI API), the iconography is all vector-based, which Fyne uses to create scalable user interfaces that adapt to the device screen density.
