Hello @sonichy, please take a look at AppImageServices and plasma-appimage-integration. The first one is a set of dbus services that provide all the methods you may require in your file manager and ensures interoperability with other applications (like software centers or AppImageLauncher). The second is a set of plasma extensions that already make use of AppImageServices and you can use as reference.

If you have any other questions or need an special feature please feel free to open an issue on the AppImageServices repo.

Hi @sonichy and welcome to AppImage. Great to hear that you want to build AppImage icons into your file manager.

If you are going the dbus route, the dbus server needs to be running, which cannot simply be assumed to be the case. So unless you are building your own distro where you can ensure that the dbus server is running, it's probably easier to just consume libappimage (and ideally link to it statically).

Documentation is (supposed to be) at AppImageCommunity/libappimage#128.

I heard that KDE can display icon of Appimage file.
DBus is too dependent, I want to use more indeppendent methord like read file.
I have already read out the ID3 cover image in mp3.
Caja, Thunar, DeepinFM can display mp4 file icon, I do not know how.

KDE is using libapimage. https://github.com/AppImage/libappimage
