It is sometimes useful to include a custom dialog in your snap:
- To display a notice that this snap is not an official application distribution from the upstream developers:
- To display a notice that some manual operations must be done for the snap to function properly due to snapd’s technical limitations:
- To display a dialog for user input:
- To display a snap obsoletion notice (when migrating snap to another namespace)
- To display snap-specific notices, including but not limited to security confinement interface warnings
The following are some ways to implement these, according to the type of application you’re snapping.
Gtk
Zenity
If you’re using gnome-platform content sharing snap, merge the following part definition to your snapcraft yaml:
parts:
# Integrate custom dialogs in your snap - doc - snapcraft.io
# https://forum.snapcraft.io/t/integrate-custom-dialogs-in-your-snap/10825
zenity:
plugin: nil
stage-packages:
- zenity
prime:
- usr/bin/zenity
- usr/share/zenity/*
otherwise:
parts:
# Integrate custom dialogs in your snap - doc - snapcraft.io
# https://forum.snapcraft.io/t/integrate-custom-dialogs-in-your-snap/10825
zenity:
plugin: nil
stage-packages:
- zenity
next adding the following layout definition:
layout:
# Fix resource relocation problem of zenity part
/usr/share/zenity:
symlink: $SNAP/usr/share/zenity
Now you should be able to call zenity after the effect of the desktop-launch launcher. Also check out The Zenity integration stage snap for an alternative.

Qarma
Qarma is a dialog implementation that is a Qt clone of Zenity. Unlike Kdialog, Qarma does not depend on KDE libraries.
To integrate Qarma merge the following part definition:
parts:
qarma-integration:
plugin: nil
stage-snaps:
- qarma/18
stage:
- usr/bin/qarma
Replace 18 to 16 for snaps targeting Ubuntu Core 16(coming soon), refer qarma --help for instructions on using Qarma.
