SUMMARY

Sometimes, when I hover over the text of a file with a really long name, the full name of the file appears in a new window which briefly opens, and then closes. 

Issue is not 100% reproducible

Video showing the issue: https://www.youtube.com/watch?v=vLU6SG-cZDQ

STEPS TO REPRODUCE
1. Have a file with a really long name
2. Hover over the file's name 
3. Full name might appear in a new window

OBSERVED RESULT

The file's full name sometimes briefly appears in a new window which closes after a split second

EXPECTED RESULT

The file's full name should always appears in a small popup beside the cursor.

Can confirm this happens sometimes. For me it happens pretty often.

I just had to set a filename to `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.txt`

Comment 2 Akseli Lahtinen 2025-02-27 09:53:57 UTC

Seems it happens only when the window with the filename has not been activated at all. But if it's somehow activated, like even clicked on once, things start working for me.

dolphinview: Add widget parameter to elided QToolTip::showText

Without this parameter the QToolTip can not always determine what
is the parent, so it will create a toplevel window in those cases.

Make sure we have dolphinview itself as a widget there, so QToolTip
and thus QtWayland can resolve what is the parent. This
avoids creating random windows when opening a tooltip.
