Table cells are not showing tooltips

[davu-all]

Describe the bug Hovering with mouse on a table's row cell a tooltip of the content is not displayed.

To Reproduce Hover with your mouse on a Table within a TableViewer. No tooltip is displayed.

Expected behavior The tooltip is displayed.

Environment:

1. Select the platform(s) on which the behavior is seen:

   • • [] All OS
   • • [x] Windows
   • • [ ] Linux
   • • [ ] macOS

2. Additional OS info (e.g. OS version, Linux Desktop, etc)

3. JRE/JDK version jdk 11.0.14.101

Version since Eclipse or SWT version since when the behavior is seen: bug showed up in 4.21. (It was working in 4.15 - no info for the version in between).

Workaround (or) Additional context I tried replacing in my system the org.eclipse.swt_3.119.0 and org.eclipse.swt.win32.win32.x86_64_3.119.0 from 4.21 with the 3.114.0 from 4.15 and the tooltip worked again.

1) Which exact Windows version is used? 2) Please provide a simple standalone SWT snippet demonstrating the problem.

Hi @iloveeclipse, Those are my OS information: Edition Windows 10 Enterprise Version 21H2 OS build 19044.2364 Windows Feature Experience Pack 120.2212.4190.0

For the snippet i will try to provide one as soon as i can (most likely after the holidays)

Don't forget to call ColumnViewerToolTipSupport.enableFor(viewer); if you are using a TableViewer.

Hi @Phillipus, it did not help.

@davu-all Are you still facing this issue? If yes can you please share a snippet to reproduce the issue.

[davu-all]

@deepika-u yes the problem is still there. I need to find the time to create a snippet from scratch.

[davu-all]

@deepika-u you can use https://raw.githubusercontent.com/eclipse-platform/eclipse.platform.ui/master/examples/org.eclipse.jface.snippets/Eclipse%20JFace%20Snippets/org/eclipse/jface/snippets/viewers/Snippet011CustomTooltips.java I tried and in no way the tooltip are showing up.

HTH!

HTH!

I tried that Snippet on Windows 10 and 11 with SWT 3.123.0.v20230220-1431 (Eclipse 4.27) and the tooltips are displayed OK.

Hi @davu-all,

As Phillipus already conveyed, I am also able to see the tooltips like below ::

As per the snippet there is an expected delay of 2secs to show the tooltip. So it is working as expected.

I have tried on below environment Eclipse SDK Version: 2023-09 (4.29) Build id: I20230705-1800 OS: Windows 11, v.10.0, x86_64 / win32 Java vendor: Eclipse Adoptium Java runtime version: 20+36 Java version: 20

Can you please confirm on the same.

It does work fine with swt tooltip (the yellow one) Yet windows native tooltip (useNativeTooltip in label provider returns true) doesn't work since this commit Downgrading org.eclipse.swt.win32.win32.x86_64 to 3.115.100 seems to "solve" the issue, and there's no native tooltip since 3.116.0

Java 17, Windows 10 Pro N 22H2 (OS build 19045.3208)

I just tested useNativeTooltip returning true on a sub-class of org.eclipse.jface.viewers.CellLabelProvider and it's working fine.

Windows 11 SWT 3.124.0

Edit - this is working in TreeViewer but not TableViewer

Actually, it is working with TreeViewer but not TableViewer. @JohnRandomdude might be worth opening a new issue for that.

Can we close this issue since #752 is anyways open?
