Re: [darktable-dev] possible data loss scenario

[Marcello Mamino]

I can reproduce the bug on Debian stable, under Xfce, master branch
just compiled, every setting default. The steps to follow are
*exactly* these

1. Open the "export selected" tab
2. Click in the "max size" filed.
3. Slowly move the pointer *downwards*
4. As soon as the pointer reaches the "allow upscaling" label just
below, the input field loses focus
5. Hover on a image, press a number, and the star rating changes

I have a second, loosely related problem with number keys and stars. I
take this opportunity to ask the devs if it's a bug or a feature.
Image X has one star. You click on the star, and the star is removed.
This makes sense because there is no other way to remove that star.
You hover on image X that has one star, you press 1, and the star is
removed. This makes no sense, because if you want to remove the star,
you can just press 0. It's also frustrating when you see image X
suddenly vanish. Is this by design?

Yours,
Marcello Mamino.

If I may offer a suggestion, I would say that grabbing the focus
should necessitate a click. Even ignoring Alexander's problem, the
current implementation is broken (at least under Linux+Xorg+Xfce). If
the "max size" field has focus and I press the arrows I can adjust the
number. Then I move the mouse down to "allow upscaling", and the
arrows adjust this setting. Fine, but now I do the opposite action and
move the pointer back to "max size": for no good reason the arrows
keep controlling the "allow upscaling" setting. It must be either
focus-follows-pointer or focus-follows-click, while now it seems to be
a random mix of these.
