pub enum ViewportClass {
Root,
Deferred,
Immediate,
Embedded,
}
Expand description
The different types of viewports supported by egui.
Variants§
Root
The root viewport; i.e. the original window.
Deferred
A viewport run independently from the parent viewport.
This is the preferred type of viewport from a performance perspective.
Create these with crate::Context::show_viewport_deferred
.
Immediate
A viewport run inside the parent viewport.
This is the easier type of viewport to use, but it is less performant at it requires both parent and child to repaint if any one of them needs repainting, which effectively produces double work for two viewports, and triple work for three viewports, etc.
Create these with crate::Context::show_viewport_immediate
.
Embedded
The fallback, when the egui integration doesn’t support viewports,
or crate::Context::embed_viewports
is set to true
.
