WinBoard PV display enhanced

[H.G.Muller]

The WinBoard alpha version now allows you to step through all PVs in the Engine-Output window, by right-clicking them. (Right-clicking the board still displays the latest PV received.)

This can be useful when running in multi-PV mode, or when you want to examine the PV of the pondering engine in a comp-comp game.

Hi Harm Geert,

This is really another great feature that you have added to winboard! I am sure winboard <your version> is going to take over the world soon!

I have one personal request about Winboard and I know that you have done that before already for personal use. Would it be possible to release a version that enables adjusting the clock (right-clicking on the clock) during a game? This would be very for operators during tournaments. This way, you can start with the real tournament timing and adjust a little bit if you lose time by moving pieces on the real board.

Keep up the good work, best wishes,
Stephan

The released version already does this, but only in Edit-Game mode. I have discovered that in practice this is not very convenient, although better than nothing. Problem is that you cannot simply restart the engine when you are done with the clock, because you of course do that when it is not your move and WinBoard does not allow you to set the engine to play a color that is not on move. So you have to wait for the opponent to move, and by that time of course you have forgotten you should still do it...

But in Machine White / Black mode, left-clicking the clock is for claiming the flag.

Perhaps I should use right-click and Shift + right-click for subtracting or adding a minute to the clock, respectively, in all modes. By convention Shift + right-click emulates a middle-click on a two-button mouse, but that would be OK, as on a real 3-button mouse the middle button is not used for anything. (Well, perhaps it also claims the flag, but it is not really neaded for that.) So left = flag, middle = add 1 min, right = subtract 1 min would be a quite workable assignment, and in the next release I might switch to that. (And also implement it in XBoard, which does not have it at all yet.)

Hi Harm Geert,

Thanx again for your great efforts! I am going to have a look at it.

Best wishes,
Stephan
