No responding in QT widget Application

[lin-dongyizhi7]

When I tested with an application of the QT Widget Application type, I could see that it successfully connected to Spix, but I was unable to obtain any window control information.

I wonder if Spix has good support for QT widgets.

Spix only supports QtQuick applications for now.

Same here. s.quit() works, nothing more.
Shouldnt it be possible to trigger QAction::trigger() via signal/slot?
I tried s.invokeMethod("mainwindow/myaction", "trigger", []) but nothing happens.
I verified the objectNames using qtobjectinspector.
