I believe the "correct" solution is to use Fl::awake() to tell the main thread to perform some operation.
If you can use C++, then you could track thread ids yourself using #include <thread>
std::thread::id main_thread; main() { main_thread = std::this_thread;
}
func() { if (std::this_thread == main_thread) { win.show(); } } On Sunday, February 28, 2021 at 8:46:57 AM UTC-5 ggar...@gmail.com wrote:
Is there a function to determine whether a piece of code is running on
the main fltk's thread?
Something like:
if ( Fl::main_thread() )
{
win.show();
}
else
{
// do nothing...
}
