/**
|
|
* \brief Send a status message to the main thread.
|
|
* The worker thread communicates status messages to the main thread by posting events to it, just as it should.
|
|
* There is just one problem: When the main thread gets a message it needs to update a listbox, which is
|
|
* rather expensive, The worker thread thus easily floods the main thread.
|
|
* The result of this flooding is that the GUI doesn't update very well, and as a consequence looks crappy.
|
|
*
|
|
* To overcome this problem, we will only send status messages at most every 50 msec.
