qml-module-qt-labs-platform 5.15.4+dfsg-1 (ppc64el binary) in ubuntu kinetic

 Qt is a cross-platform C++ application framework. Qt's primary feature
 is its rich set of widgets that provide standard GUI functionality.
 .
 This package contains the experimental Qt Labs Platform module that provides
 platform integration: native dialogs, menus and menu bars, and tray icons.
 It falls back to Qt Widgets when a native implementation is not available.
