render

Overview ¶

Package render provides the public API for creating a widget.Canvas backed by a gg.Context.

This package is a thin wrapper around the internal render implementation. Host applications use it to bridge the gogpu/gg 2D rasterizer with the ui widget drawing pipeline.

cc := ggcanvas.Context()                       // *gg.Context
canvas := render.NewCanvas(cc, width, height)  // widget.Canvas
window.DrawTo(canvas)                          // draw widget tree

Package render provides the public API for creating a widget.Canvas backed by a gg.Context.

This package is a thin wrapper around the internal render implementation. Host applications use it to bridge the gogpu/gg 2D rasterizer with the ui widget drawing pipeline:

cc := ggcanvas.Context()                       // *gg.Context
canvas := render.NewCanvas(cc, width, height)  // widget.Canvas
window.DrawTo(canvas)                          // draw widget tree

The returned widget.Canvas supports all drawing operations required by widgets: rectangles, rounded rectangles, text, lines, clipping, and push/pop state. GPU-accelerated operations (SDF shapes, clip regions) are handled transparently by the underlying gg.Context.
