Constructors and Destructors

◆ QScriptEngineDebuggerBackend()

QScriptEngineDebuggerBackend::QScriptEngineDebuggerBackend ( QScriptEngineDebuggerFrontendPrivate * frontend )

Creates a new QScriptEngineDebuggerBackend object for the given engine.

Warning: This function is not part of the public interface.

The back-end will forward events to the given frontend.
