you can take a look at the widget explorer in kde-
workspace/libs/plasmagenericshell/widgetsexplorer/package/contents/ui

it has a thing that behaves like a tooltip even if with custom content

i wonder if there should also be an option to put a generic Component in it 
besides the usual tooltipdata properties, but is probably overkill right now

import org.kde.qtextracomponents

QPixmapItem {
  pixmap: myc++class.pixmap
}

how are you positioning it? dialog.popupPosition? you should position it 
before actually showing it

shouldn't have any, it should use whatever width/height the main item has

yeah, i think bypasswindowmanagerhints is necessary right now :/
