The OpenD Programming Language

runInGuiThread

Runs the given code in the GUI thread when its event loop is available, blocking until it completes. This allows you to create and manipulate windows from another thread without invoking undefined behavior.

If this is the gui thread, it runs the code immediately.

If no gui thread exists yet, the current thread is assumed to be it. Attempting to create windows or run the event loop in any other thread will cause an assertion failure.

Return Value
