Suggestions for my snap (PDF Mix Tool)

scarp · May 8, 2021, 11:42am

Hello all,
I’m the developer of PDF Mix Tool, and I maintain its snap package too. The new version 1.0 of PDF Mix Tool requires Qt >= 5.11, so I switched the snap to use kde-frameworks-5-core18-sdk, following the official guide. The repository containing the snapcraft.yaml I created is hosted on github. The package is working for me, but there are some problem:

the application doesn’t follow the system UI theme
a user is reporting he can’t open files. I can’t reproduce the bug and I don’t know is someone else is affected
calls to QDesktopServices::openUrl(QUrl url) aren’t working. I read is a common problem and I found a possible workaround here

So I’d like to ask you if my snap is OK or there is something I can do to improve it.

Best,
Marco

Qt doesn’t fallback to internal file dialog implementation when xdg-desktop-portal is not available, so if your user doesn’t have xdg-desktop-portal and one of its backends with implemented FileChooser interface, they won’t get any file dialog. The only way to fix that is to re-implement the XDP FileChooser spec on your own and fallback to QFileDialog with QFileDialog::DontUseNativeDialog flag set when XDP file dialog fails.

Thank you for your quick reply! My user solved the issue installing xdg-desktop-portal-gtk. I’ve added a note in the snap’s description
