Hi all,
I'm writing a Kwin script to automatically set an unread count badge to an
app's launcher icon by parsing its title.
I'm stuck at the part where I need to call an DBus API, but always get
"Received D-Bus message is error". I appreciate any help to show me where I
got it wrong, or callDBus just doesn't support passing a{sv} argument yet.
This is the method that I need to call:
https://wiki.ubuntu.com/Unity/LauncherAPI#Low_level_DBus_API:_com.canonical.Unity.LauncherEntry
I can use gdbus and it successfully update the launcher's icon badge:
gdbus emit --session --object-path /com/canonical/unity/launcherentry/1
--signal com.canonical.Unity.LauncherEntry.Update
"application://chrome-ebcgcbpjedmohalnmiodnfidggpfcehe-Default.desktop"
"{'count-visible': <true>, 'count': <2>}"
But when I attempt to use callDBus in my script, it fails:
callDBus(
"com.canonical.Unity", // Service
"/com/canonical/unity/launcherentry/1", // Path
"com.canonical.Unity.LauncherEntry", // Interface
"Update", // Method
"application://chrome-ebcgcbpjedmohalnmiodnfidggpfcehe-Default.desktop",
{ "count-visible": true, count: 1 }
);
I tried to read the source code of callDBus and failed to understand
whether it supports a{sv} or not, since I'm not familiar with Qt and C++.

Thanks in advance for any help.
