wxApp::Pending+wxApp::Dispatch seems to be exactly what I need.
I don't know what your definition of normal is, but my question seems
perfectly normal to me. What I want to achieve is to have several Lua
frameworks working together in a single thread (because Lua is not
thread safe). Each of my frameworks need to be updated several times a
second, but I can't give application main loop control to any of
these, so I need to make them cooperate.
Example :
void F1::MainLoop()
{
bool quit;
Message message;
while (message = F1::GetMessage_Blocking())
{
F1::ProcessMessage(message);
}
}
void F2::MainLoop()
{
bool quit;
do
{
F2::Render();
quit = F2::ProcessInput();
} while (!quit);
}
void F3::MainLoop()
{
bool quit;
do
{
F3::Update();
if (F3::LastError())
quit = true;
} while (!quit);
}
void InterleavedMainLoop()
{
bool quit = false;
Message message;
while (true)
{
// Update framework F1
while (F1::IsMessagePresent())
{
message = F1::GetMessage_NonBlocking();
if (message)
F1::ProcessMessage();
else
quit = true;
}
if (quit) break;
// Update framework F2
F2::Render();
quit = F2::ProcessInput();
if (quit) break;
// Update framework F3
F3::Update();
if (F3::LastError())
quit = true;
if (quit) break;
// Main application control refresh rate
usleep(10000);
}
}
Replace F1 with wxLua, F2 with my OpenGL renderer and F3 with john
doe's network framework if that makes things clearer. The basic idea
is that an extension module should not take control of the
application. There are a lot of multi-threaded solution to this kind
of problem, but in some context a full thread control is a big
requirement for an extension module.
