KGTK does not work with Inkscape and VSCode on Arch Linux

Hello!

And VSCode still opens the GTK2 Dialog.

I assume vscode just uses the same code as chromium? chromium has really ugly logic for determining the dialog it should use, so not surprised if it doesn't work.

as for inkscape, did you build it against gtk3 or gtk2? inkscape is still gtk2.

Yes, I suspect VSCode is based on Chromium 76 and uses still uses Electron 6, which may not work with KDE dialog. My Google Chrome, which is 81, here on Arch Linux, opens the KDE dialog normally.

I built the beta version of Inkscape from AUr (check the https://aur.archlinux.org/packages/inkscape-git). The PKGBUILD does not tell which GTK version it will be built against, but the error indicate sthat Inkscape is built against GTK2.

The Arch Linux package requires gtk2>=2.6. The tarballl also includes a gtk2 folder with ktgk.c file. Doesn't that imply KGtk should work with GKT2 applications like Inkscape? Is there a step we missed?
