Added external lib test
Added external_lib_test
New project thread_test
Updated MainWindow class
Added threading test code, but doesn't work well ...
Use QTimer to invoke loop(). But it's not still working... :-(
Fixed stupid C language mistake
Added reset function for TestObject.
But this code doesn't work as I expected because loop() doesn't
return execution for event loop of the thread.
So the object cannot handle signal connected to the object.
I need to solve this problem asap.
Added info about yieldCurrentThread
Fixed to use Qt::DirectConnection
Now the code works as I expect.
Use QConcurrent::run() for creating threads.
It worked fine! I like it so much!!
