ZUIL

[!CAUTION] WIP

[!IMPORTANT] NOT TESTED ON WINDOWS
the build.zig links some libraries as system libraries
which i assume doesnt work on windows

ZUIL (Zig UI Library)

retained mode gui framework written in zig

using zglfw, zopengl, plutosvg, harfbuzz and freetype libs

current features/progress

• asset/file registry
• resource system
• input system (keyboard and mouse only)
• rendering abstraction (shaders are written in GLSL)
• text rendering (WIP)

examples

widgets

widgets are created using builder functions

// .c for common builder functions
widgets.container()
.c.size(.{.dp = 1200}, .{.percentage = 1})
.color(colors.WHITE)
.child(
	widgets.list()
	.c.size(.fill, .fill) // fill is same as .{.percentage = 1}
	.direction(.vertical)
	.spacing(1)
	.children(.{
		widgets.icon()
		.c.size(.{.dp = 200}, .{.dp = 200})
		.c.keepSizeRatio(true)
		.icon("icon.svg")
		.build(),
		widgets.container()
		.c.size(.{.dp = 50}, .{.dp = 30})
		.c.eventCallback(containerClick) // fn (*ZWidget, *const ZEvent) callconv(.c) c_int
		.color(colors.rgb(0, 1.0, 0.5))
		.build(),
		widgets.container()
		.c.size(.{.pixel = 50}, .{.dp = 30})
		.build(),
		widgets.container()
		.c.size(.{.mm = 50}, .{.dp = 30})
		.build(),
		widgets.container()
		.c.size(.{.percentage = 0.5}, .{.dp = 30})
		.build(),
	})
	.build()
)
.build();

test project

there is a test/example project in the test directory

keybinds:

• space: change the layout
• F1: spawn a new window (currently broken see comment in render function inside src/app/window.zig)

project structure

directories in src dir:

• core has the base widget system
• app has glfw specific things and can be used to create windows that use the core widget system
• widgets has the default widgets/shaders
