Two finger scrolling in Netbeans triggers right click

[Claes]

Whenever I use the two fingers to scoll up or down in netbeans, it always triggers a right click, opening the context sensitive menu, and interrupting the actual scrolling.
Does not happen if I click and drag the relevant scroll handle instead of using two finger scroll.

Does not happen in any other application, such as firefox, chromium or libreoffice.

It could possible be java related, I may just not have any other java based apps, but searching for java and various variations of right click and scrolling didn't find me any bugs.

Status changed to 'Confirmed' because the bug affects multiple users.

Same here on 12.10 and netbeans 7.2

It looks like it affects other java apps:

Also affects Arduino. It would be good to find a way to either fix or disable 2-finger horizontal scrolling in java apps rather than having to disable the feature across the whole desktop.

Waiting for a fix :( Its really annoying

I had this bug too, but it started when I enabled two fingers horizontal scrolling.

I executed this:

    synclient HorizTwoFingerScroll=0

And now it's gone.

Thanks, jpadif! Command you mentioned solved my problem.

[Josef Kufner (jk-4)]

This bug occurs if you have horizontal wheel on your mouse. Scrolling to sides is interpreted incorrectly. Very, very annoying...

(Netbeans 7.4)

eclise is made in java too, but horizontal scroll there works, does anybody understand why it doesnt work in netbeans?

[jenskapitza (j-kapitza)]

using java8 and netbeans 8 bug is in 14.04.

disabling the two finger scroll is not a solution ;(

are any other hints?

[Ogilvierothchild (ogilvierothchild)]

I'm using java8 and netbeans 8 in ubuntu 14.04.

It also is triggered by using middle-button scrolling to the side, making the application near-unusable for browsing code on a thinkpad without an external mouse (since 2 finger scroll and trackpoint scroll both trigger a popup menu constantly).

This appears to be relevant

I had the same problem and I know how annoying it is when using Netbeans. I found a work around for this.

On Ubuntu 14.04.1 LTS, under Settings -> Mouse and TouchPad.

I have:
Disable while typing (checked)
Tap to click (un-checked)
Two finger scroll (checked)
Natural scrolling (unchecked)

The tap to click feature was causing the problem, it seemed on some applications scrolling with two fingers was considered as both click (since it's a tap) and scroll (since it's two fingers). Removing the check for 'tap to click' solved it for me.

Hope this helps.

I had the same problem and it was because of horizontal scroll. Ubuntu 14.04.01 LTS
I deactivate / activate the horizontal scroll for use with netbeans using a simple command line:

$ gsettings set org.gnome.settings-daemon.peripherals.touchpad horiz-scroll-enabled false

$ gsettings set org.gnome.settings-daemon.peripherals.touchpad horiz-scroll-enabled true

Hello

i'm currently testing 15.04 and i have this issue on a Asus Zenbook ux303 having a focal tech trackpad. As described here http://askubuntu.com/questions/50749/horizontal-scrolling-treated-as-right-click-in-java-applications , using the command 'synclient HorizTwoFingerScroll=0' disable this unwanted right click for me on Netbeans without disabling the two finger scrolling
