#18911 new defect

Clicking on layer's opacity slider "toggles" instead of sliding

Reported by: blackboxlogic@… Owned by: team
Priority: normal Milestone:
Component: Core imagery Version:
Keywords: template_report layer slider opacity Cc: simon04


What steps will reproduce the problem?

  1. Have JOSM open with a layer.
  2. In the 'layers' pane, click the button labeled "change visibility of the selected layer"
  3. In the popup, notice that there is an opacity slider, currently at 100%
  4. Click in the middle of the slider to select a value near 50%

What is the expected result?

I expect the slider to slide to the position/value clicked by the user

What happens instead?

The slider acts more like a toggle, jumping in the direction of the click to the extreme value in that direction.

Please provide any additional information below. Attach a screenshot if possible.

This slider behaved as expected previously. I do not know when the behavior changed. Recently I have updated JOSM to latest and updated my JAVA version.

Behavior of the sliders changed with r15660 as of bug #15946 in January 2020.

I see the slider moving in 10% steps to the mouse pointer when the left mouse button is hold down. Holding down a mouse button while not dragging seems to be very seldom.

Click in the middle of the slider to select a value near 50%

I don't think this is related to r15660 since the change in r15660 only triggers after a double-click. Also, reverting r15660 doesn't change the described behaviour.

Replying to Hb---:

I see the slider moving in 10% steps to the mouse pointer ...

Occasionally the slider overshoots the mouse pointer and jumps to the extreme value as the bug reporter stated. 1.8.0_242-b08 AdoptOpenJDK x64 on Win 7 x64.
