D19873: [image-wallpaper] Fix horizontal alignment of the "Positioning:" row

[Marco Martin]

mart added a comment.


  So,
  FormLayout has api to align two or more of them with each other, which is the list property FormLayout.twinFormLayouts
  
  I wonder if there is a way to make the parent and child formlayouts visible ot each other to use such property.
  
  the parent is in plasma-desktop/desktoppackage/contents/configuration/ConfigurationContainmentAppearance.qml, loading the individual wallpapers config in the stackview at line 162.
  
  so, we could try something like:
  the wallpaper configs will expose a formLayout property.
  the main formLayout has something like
  twinFormLayouts: stack.item && stack.item.formLayout ? [stack.item.formLayout] : []
  
  then the parent layout may be i guess injected at instantiation as a property of the wallpaper plugin, so the child formlayout can set twinformlayouts as well
  
  this is all untested, so is a bit of R&D project, but if you would like to give a try it may be finally the properfix(tm)
