Module surface 

Surfaces — widgets that draw themselves.

A Surface paints its box with any yog-gfx call (shaders, buffers, Draw2D) and may take the pointer: a casting grid, a graph, a minimap. The tree refers to one by id (widget::surface, .yui <Surface source="mymod:grid"/>); the code registers the drawing object under that id with register. An id nothing is registered under draws nothing.

struct Graph;
impl yog_ui::Surface for Graph {
    fn paint(&self, gfx: &GfxContext, rect: Rect) {
        gfx.draw2d().rect(rect.x, rect.y, rect.x + rect.w, rect.y + 1.0, 0xFFFFFFFF);
    }
}
yog_ui::surface::register("mymod:graph", std::sync::Arc::new(Graph));

Enums

Pointer

A pointer event on a surface, in coordinates local to its box (0,0 = top-left corner).

Traits

Surface

What a surface widget draws and how it takes the pointer — see the module docs.

Functions

get

The surface registered under id.

register

Makes surface what <Surface source="id"/> widgets draw (replacing the one registered before).

unregister

Drops the surface registered under id.
