[Impact]

Mousewheel scrolling over the pathbar buttons in
Caja does nothing. It should switch between the
buttons in case when not all of them are visible
in the window, for example, when window isn't wide
enough. It worked that way in GTK+2 builds of Caja,
but stopped with migration to GTK+3 (in 1.18).

The patch attached to this report fixes the issue.

The fix is already present in Artful and tested by
developers and users. Would be nice to backport it
to Zesty as well, as it's a regression compared to
previous Caja versions.

[Test Case]

Steps to reproduce:
- launch Caja
- move to some directory 4-5 levels deep (so that
  the pathbar has enough buttons to test)
- reduce width of Caja window to make some pathbar
  buttons disappear
- use mousewheel scroll over any pathbar button

The scroll will do nothing.
To see what it should actually do, use left/right
arrow buttons on the sides of the pathbar.

[Regression Potential]

Between low and none. The patch only affects the
processing of scroll events in the pathbar.

[Other Info]

The patch is included into the debdiff attached to
bug 1680604.

The debdiff contains patches to fix bug 1680604,
bug 1683653, bug 1688687. See other reports for the
corresponding SRU templates.

Hello Matthew, or anyone else affected,

Accepted caja into zesty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/caja/1.18.1-0ubuntu2.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-zesty to verification-done-zesty. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-zesty. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

While I've accepted this the "Regression Potential" section is rather weak. What kinds of testing should be done to ensure the fix didn't break anything else?

There's not much to say, really. Adding scroll event to the set of events that a widget will receive doesn't affect other types of events on it (mouse button press, key press and others).

Testing in Zesty. It's done after testing the fix for bug 1680604, so the packages are already updated to version 1.18.1-0ubuntu2.1 from zesty-proposed.

- launched Caja
- changed to /usr/lib/x86_64-linux-gnu/mate-notification-daemon/engines/
- reduced the window's width so that some pathbar buttons would be hidden
- used mousewheel scroll over all pathbar buttons
- used mousewheel scroll over left/right arrow buttons on the sides of the pathbar
- clicked on arrow buttons as well - they do the same as mousewheel scrolling
- also checked that all pathbar buttons work properly (they do)

The scrolling works. It does the same as the arrow buttons on the sides of the pathbar.
Scrolling down or clicking on right arrow reveals hidden buttons at the end of the pathbar.
Scrolling up or clicking on left arrow does the same at the start of the pathbar.
