\section{\class{wxThreadHelperThread}}\label{wxThreadHelperThread}
|
|
|
|
The wxThreadHelperThread class is used internally by the
|
|
\helpref{wxThreadHelper}{wxthreadhelper} mix-in class. This class simply
|
|
calls \helpref{wxThreadHelper::Entry}{wxthreadhelperentry} in its owner class
|
|
when the thread runs.

\membersection{wxThreadHelperThread::wxThreadHelperThread}\label{wxthreadhelperthreadctor}
|
|
|
|
\func{}{wxThreadHelperThread}{\void}
|
|
|
|
This constructor simply initializes member variables.
|
|
|
|
\membersection{wxThreadHelperThread::m\_owner}
|
|
|
|
\member{wxThreadHelperThread\& }{m\_owner}
|
|
|
|
the \helpref{wxThreadHelper}{wxthreadhelper} object which holds the code to
|
|
run inside the thread.
|
|
|
|
\membersection{wxThreadHelperThread::Entry}\label{wxthreadhelperthreadentry}
|
|
|
|
\func{virtual ExitCode}{Entry}{\void}
|
|
|
|
This is the entry point of the thread. This function eventually calls
|
|
\helpref{wxThreadHelper::Entry}{wxthreadhelperentry}. The actual worker
|
|
thread code should be implemented in
|
|
\helpref{wxThreadHelper::Entry}{wxthreadhelperentry}, not here, so all
|
|
shared data and synchronization objects can be shared easily between the
|
|
main thread and the worker thread.
|
|
|
|
The returned value is the thread exit code which is the value returned by
|
|
\helpref{Wait()}{wxthreadwait}.
|
|
|
|
This function is called by wxWindows itself and should never be called
|
|
directly.
|
|
|
|
\membersection{wxThreadHelperThread::CallEntry}\label{wxthreadhelperthreadcallentry}
|
|
|
|
\func{virtual ExitCode}{CallEntry}{\void}
|
|
|
|
This is a convenience method that actually calls
|
|
\helpref{wxThreadHelper::Entry}{wxthreadhelperentry}. This function
|
|
eventually calls \helpref{wxThreadHelper::Entry}{wxthreadhelperentry}.
|
|
The actual worker thread code should be implemented in
|
|
\helpref{wxThreadHelper::Entry}{wxthreadhelperentry}, not here, so all
|
|
shared data and synchronization objects can be shared easily between the
|
|
main thread and the worker thread.
|
|
|
|
It must be declared after \helpref{wxThreadHelper}{wxthreadhelper} so it
|
|
can access \helpref{wxThreadHelper::Entry}{wxthreadhelperentry} and avoid
|
|
circular dependencies. Thus, it uses the inline keyword to allow its
|
|
definition outside of the class definition. To avoid any conflicts
|
|
between the virtual and inline keywords, it is a non-virtual method.
|
|
|
|
The returned value is the thread exit code which is the value returned by
|
|
\helpref{Wait()}{wxthreadwait}.
