- I’ve read all GTK, LibAdwaita, tutorials that I could find.
- I’ve read Documentation on AdwApplication, GtkApplication, GApplication.
- I’ve tried to read Startup Notification standard of freedesktop.
I cannot seem to find my answer.
Can anyone here tell me exactly what I need to do in order to make my application to send ‘Startup Notification’ to the system when it launches
My app's desktop file
[Desktop Entry]
Type=Application

Note: I’ve set StartupNotify to false AFTER experiencing the problem
