Description David 2020-11-20 21:53:59 UTC

SUMMARY
For some reason, I cannot copy large amounts of text from GTK appa into Kate/KWrite. Pastying works correctly if the text is copied from a QT text editor though.

STEPS TO REPRODUCE
1. Create a large text file with >10k lines (e.g. this: https://github.com/david-cortes/cmfrec/blob/master/src/collective.c).
2. Open said file in e.g. gedit or sublime.
3. Launch a kate/kwrite window.
4. Paste the text into kate/write. 

OBSERVED RESULT
Nothing happens

EXPECTED RESULT
Should paste the copied text

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 5.19.5
KDE Frameworks Version: 5.74.0
Qt Version: 5.15.1

Sory missing step:

STEPS TO REPRODUCE
1. Create a large text file with >10k lines (e.g. this: https://github.com/david-cortes/cmfrec/blob/master/src/collective.c).
2. Open said file in e.g. gedit or sublime (GTK text editors).
3. Select all text from that file in the text editor and copy it to the clipboard.
4. Launch a kate/kwrite window.
5. Paste the text into kate/write.

Thanks for the report David, I've just tested this with Kate 20.08.3 and gedit 3.36.2 on openSUSE and I am unable to replicate this issue, the text is pasted immediately.

Are you able to test with a fresh user and if that also fails with a live ISO of another distro like openSUSE Tumbleweed?

Comment 5 Christoph Cullmann 2021-03-31 20:49:10 UTC

True, doesn't work.

 QApplication::clipboard()->text(QClipboard::Clipboard)

just doesn't return the text :/

Comment 6 Christoph Cullmann 2021-03-31 21:05:11 UTC

Yeah, Qt issue, Qt Creator can't paste that either...

Comment 8 Szczepan Hołyszewski 2021-06-18 13:43:05 UTC

Is there a Qt issue on their tracker that I can follow?

Comment 9 Eric Armbruster 2022-11-02 11:58:07 UTC

I cannot reproduce with Kate 22.08 and Plasma 5.26. Is this still an issue?

Comment 10 Justin Zobel 2022-11-02 22:17:02 UTC

Same I can no longer reproduce this issue with the file, copying from gedit to write 22.08.1, Qt 5.15.6 on Fedora 37.

Can anyone else who was experiencing the issue still reproduce it?

Comment 11 Greg Lepore 2022-11-03 11:30:04 UTC

Issue appears fixed to me, I was able to copy several megabytes of data from Firefox to Kate with no problems. Previously this would fail.

Comment 12 David 2022-11-03 17:31:16 UTC

Not reproducible anymore.
