Error when scrolling with mouse

scottkosty commented 5 years ago

I can scroll with + but when I try to scroll with my mouse, I get an error. Here's a minimal example:

library(zoom)
plot(1:10)
zm()

After running that, if I scroll with my mouse, I get the following error:

Error in if (mevent == "scrollDown") { : argument is of length zero

Here is some information on my system:

Can you reproduce?

By the way, thank you for your work on this nice package. It made it easy to debug a specific problem I was having.

I have the same issue. With a feshly installed version of zoom from CRan. After the bug occurs the window does not respond any more to new inputs.

Hi, I can definitely reproduce. Unfortunately, R seems to have dropped the support of scroll events: an event is returned but without distinguishing scroll up and scroll down. I asked a stackoverflow question, but for now, the last version on github is not offering to scroll and should not fail when doing so.

@cbarbu thanks for your response and for maintaining this package. Just for archival purposes, I think the commit fe10d9cb16224e3f30f53af097190704c7a36bb0 is related to this issue.

I'm looking into the regression (in R) and along the way came across #8.

Here is the upstream bug report: https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17684 Since I don't think this GH issue is due to a bug in the zoom package, feel free to close it.
