SUMMARY KParts can't be embedded in Kirigami applications. KParts are one of KDE’s biggest selling points for developers, in my eyes - being able to reutilize GUI implementations of functionality like any CLI application would, as if the developer were using <iframes> in HTML. Few, if any, other frameworks provide this capability. EXPECTED RESULT I should be able to use KParts with Kirigami.
