mainthreadharness

Overview ¶

Package mainthreadharness drives an AppKit run loop so the main thread dispatch tests can schedule work at it and nest a loop inside a dispatched callback, as a modal dialog or an open menu does.

It is a package of its own, rather than a file in package application, because the go tool does not allow cgo in _test.go files and these helpers must not be linked into the shipped package. Only the tests import it.

Everything here is macOS only; on other platforms the package is empty.
