Issue ID

UUM-137019

Regression

No

ListView horizontal scroll bar remains visible when horizontalScrollingEnabled is false by default in UIToolkit

UI Toolkit Controls

-

How to reproduce:
1. Open the attached “IN-135865” project
2. Open the scene “SampleScene”
3. Enter Play mode
4. In Game view, observe the ListView UI element

Actual result: ListView has a horizontal scroll bar
Expected result: ListView has no horizontal scroll bar

Reproducible in: 2023.1.0a1, 6000.0.70f1, 6000.3.10f1, 6000.4.0b11, 6000.5.0a8

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Workaround: Retrigger “listView.horizontalScrollingEnabled” by toggling it to “true” and then back to the intended value “false” with a script

Note: m_HorizontalScrollingEnabled is “false” by default in the BaseVerticalCollectionView, however, the ScrollView's horizontalScrollerVisibility is “Auto” by default. The first line of the property checks if m_HorizontalScrollingEnabled has changed, if it hasn't, nothing is applied.

    Also in my case the issue is only present in an application build (Web platform) and not in the editor. If any of this helps with ListView then that's great

    Update: For my own workaround of the menu issue, I was able to manually force scrollView.horizontalScrollerVisibility = ScrollerVisibility.Hidden, for the ScrollView in the popup element, using a custom manipulator attached on certain events.

    Something changed in the versions I listed in regards to ScrollView, however I still can't reproduce it in a test project.

    Note I haven't tried the suggested workaround, and in my case I was unsuccessful in reproducing it with a fresh test project

    I'm voting on this issue as I have a similar experience but in relation to GenericDropDownMenu, DropDownField and EnumField menus.

    My experience is that it appeared in v6000.0.54f1, v6000.1.11f1 and v6000.2.0f1
