QTVCP/QTDragon HD: machinelog and integrator_log do not scroll down reliably

[Eckeneckepen]

Here are the steps I follow to reproduce the issue:

1. Start qtvcp -di qtdragon_hd
2. Do not open Status view
3. Home all axes
4. MDI: send 20 times: (debug, test)
5. MDI: send (debug, TEST)
6. Switch to Status view: TEST is not visible (slider not down)
7. Switch Status view to System Log: slider is not down

This is what I expected to happen:

To see always the newest data (slider on lowest position).

This is what happened instead:

Slider is not on lowest position.

It worked properly before this:

n/a

Information about my hardware and software:

LinuxCNC 2.9.3

Fix which works for me (see attached patch):

1. overload showEvent() function in linuxcnc/lib/python/qtvcp/widgets/machine_log.py
2. I don't understand the periodic check function, but without the slider down call, the System Log lags behind if you observe the Machine Log and go back to System Log.

In my testing, it seems only the showEvent needs the scroll code.
Do you see something different?
