Body

A body is a frame that contains the main app content (core.Body). It is contained within a scene, which is the root node of a window or dialog.

The b widget in these docs examples represents the body that you typically add widgets to:

core.NewButton(b).SetText("Click me")

This is docs shorthand for:

package main

import "cogentcore.org/core/core"

func main() {
	b := core.NewBody("App Name")
	core.NewButton(b).SetText("Click me")
	b.RunMainWindow()
}

Methods

Because the body is typically the easiest content container to access, there are various helper methods on it. For example, to create a stage, you can use methods like core.Body.RunMainWindow as above. See the stage docs for more info on these methods and how to customize the way a window or dialog is displayed.
