[gtk3] Scrollback lines not configurable

[egmontkob]

"Scrolling" tab.

The input field for the "Scrollback lines" number is active, however, the - and + buttons are insensitive. No matter what I type for the number (which is 0 initially), the scrollback is only 1024 lines. As I close and reopen the prefs window, the number is 0 again.

Expected: -/+ buttons active. The displayed number reflects the current value. The entered number is saved respected. Ideally another option (checkbox) for infinite scrollback.

(Technical: VTE stores the scrollback in compressed and encrypted, unlinked temporary files under /tmp.)

On a side note, the checkboxes "On output" and "On key stroke" don't make too much sense to me without a header like "Scroll to bottom".

Let me mention here that the other GtkSpinButton, namely "Max tab name length" on the General tab also suffers from the same problem.

Thanks!

Some followup nitpicking:

The default value is 1024. The +/- buttons jump on multiples of 1000, and any manually entered value is also rounded.

• The default should be a value that is also configurable later.

• Spinbuttons can be set up in a way that the +/- buttons jump in bigger steps, yet any value entered in between is also accepted.

• There's no technical reason in VTE for preferring powers of two at all. IMHO the default should be a more user-friendly value (a round number in decimal rather than binary).

By the way, jumping by 1000 is a really nice thing that I'd like to have for gnome-terminal too :-)

I agree :) would be fun to have a exponential-like (rounded to 100s) increment

Update to HEAD?
