This is also relevant to batch scripting. We need to stay in UTF8 to be safe. Thanks to Robert Hänggi for reporting this issue.

\class Response
|
|
\brief Stores a command response string (and other response data if it becomes
|
|
necessary)
|
|
|
|
The string is internally stored as a std::string rather than wxString
|
|
because of thread-safety concerns.

\class ResponseQueue
|
|
\brief Allow messages to be sent from the main thread to the script thread
|
|
|
|
Based roughly on wxMessageQueue<T> (which hasn't reached the stable wxwidgets
|
|
yet). Wraps a std::queue<Response> inside a wxMutex with a wxCondition to
|
|
force the script thread to wait until a response is available.
