Icon theme "elementary" not found.

[ruben2020]

Is this Ubuntu 19.10 or Lubuntu 19.10? Is it LXDE or LXQt?

[LSergM]

This is Lubuntu 19.10.
I am not sure about second question but It looks like

• Finding desktop environment...found as 'LXDE'

I played around with different settings of Icons Theme and got following result

[ruben2020]

Did you build for Qt5 or Qt4?

[LSergM]

I used Qt 5 to build it.

[ruben2020]

To get rid of the error "Icon theme elementary not found", use this:
sudo apt-get install elementary-icon-theme

However, the closing of CodeQuery after fixing that, only happens with Lubuntu 19.10. It does not happen with Ubuntu 19.10. It also does not happen with Lubuntu 18.04. I use Arch Linux and it also does not happen on the latest Arch Linux.

So, I think this is a problem of Lubuntu 19.10.

[ruben2020]

Using CodeQuery based on Qt4 does not have this problem on Lubuntu 19.10. Using CodeQuery based on Qt5 does not have this problem on Ubuntu 19.10. Would you consider switching to Ubuntu 19.10?

[LSergM]

After rebuilding CodeQuery by Qt4 I was able to open a db file. So this is great.
But than I have tried to use grep command and got segmentation fault

[ruben2020]

Thanks. I just fixed the segmentation fault and committed to the develop branch. But there is still some problem with the function list on the bottom left when using grep. Still need to check that.

[ruben2020]

Good news @LSergM - I have fixed the function list bug for grep. Now committed to the develop branch. I guess we can soon approach release of a new version. Please do try it out and let me know if you're satisfied with it. Thank you very much for your support.

[LSergM]

@ruben2020 I have tested the new update and it looks great. Thank you for your work and help.
