Hi Thomas,
Thanks for your reply :)
1. it is NOT a bug about Apper or QJade.
Because Apper and QJade uses PackageKit-Qt, a Qt bindings for
PackageKit. When it calls installPackage function of PackageKit-Qt,
there is pk_transaction_obtain_authorization function in PackageKit to
call PolicyKit relative dbus async APIs such as
polkit_authority_check_authorization.
the process shown as below:
Apper install package -> PackageKit-Qt call installPackage -> PackageKit
do PolicyKit authorization -> polkitd -> Polkit-Qt -> Polkit-KDE
so there is NO Apper assoicate WID for AuthDialog constructor.
2. KWindowSystem::forceActiveWindow sometimes worked BUT ...
Sometimes it FAILED to force active window to act like modal one, for
example, Apper or QJade covered the Polkit-KDE AuthDialog window, but I
simply setWindowFlags for AuthDialog to force it as _NET_WM_STATE_ABOVE,
I experienced it :)

Hi KDE developers,
My colleage reported a bug to me, it is about PolicyKit1-KDE AuthDialog
UI behavior issue, the AuthDialog could not show as TOP_LEVEL
That's called "_NET_WM_STATE_ABOVE" - "toplevel" usually refers to a
window with the root window as parent drawable.
installing some App via Qt frontend of PackageKit, for example, Apper or
QJade https://github.com/AOSC-Dev/QJade
Seems an apper bug.
You want to pass the Apper window WId as last parameter to the
AuthDialog() constructor.
This will make the AuthDialog modal (and transient) for that window.
The only problem occurs if you have no window to assiciate the
AuthDialog with. In this case you may wish to enforce activation (see
KWindowSystem::forceActiveWindow()) which is legit, if the dialog
appears as result of a direct user interaction (eg. with some systray
icon etc.)
Cheers,
Thomas
