WindowError

Why a window could not be created.

public class WindowError: Error

constructor

Creates an error with a stable machine code and a readable message.

public constructor(code: string, message: string)

code

The machine-readable reason. ENODISPLAY means no display is available, such as on a server, under Node, or when the platform window system failed to start. ETHREAD means the call came from a Task worker instead of the program's main thread, the only thread allowed to own windows. ENOTFOUND means Window.canvas found no <canvas> element with that id. EINVAL means the description has a non-positive size. EWINDOW means the platform refused to create the window.

public fun code(): string

message

A human-readable description that includes the platform's own message when it gave one.

public fun message(): string
