Tabbing from an exposure value field doesn't set value

[Don Johnston]

I'm running Hugin 2014.0.0 built by Matthieu DESILE on OS x Yosemite 10.10.5 (14F27).

In the Preview panel of the “Fast Panorama preview” if I set the EV using the keyboard it doesn’t take effect if I tab out of the entry box. After running the Create Panorama the EV value gets set back to what it originally was. When entering a value from the keyboard I have to use the enter/return key for the value to be set.

If I use the up/down arrows to change the EV the intensity of the image does change as expected.

Also … while clicking on the up/down arrows, or entering a value, the Preview image doesn’t change intensity. I have to uncheck the Photometrics box and then recheck it to see any change. This seems to only happen after I've stitched the images. If I load two images, then go to the Preview panel, the intensity of both images changes as I change the EV values. Then after running Align the problem shows up.

I find that the best way to use the EV value is to uncheck the Photometrics, click to change the EV value to adjust the problems in one part of the image, and then recheck Photometrics.

Also I received the following from another user that tested this out.

I just tried on Win 7 SP1 64bit bit hugin 2015.0.0 and could partially reproduce the problem:

- Opened an existing project and changed EV in preview window by keyboard: preview did not change
- clicked an arrow and the value in the text box did not change by 1/3EV from the previously entered
  value but by 1/3EV from the original value (the value before I entered one by hand), this time preview did change.
- Ctrl-Z to revert and saved project in a new file (for not to mess it up)
- again changed EV by keyboard: preview did change now
- stitched and result was like preview

So it seems to depend on the circumstances.

This affects only the exposure value field in the fast preview window. In all other field tabbing works already.
Fixed for exposure value field in changeset ce64477643a0.
