Selecting item in QML TreeView does not change isSelected of item

[ocgltd]

I have created a simple TreeView in QML, with several levels of nesting. I have also created an "itemDelegate" and a "rowDelegate"; both of which switch background color between red/black bound to their respective isSelected.

When I click on an item the ROW color changes, but the item does not. I confirmed the itemFlag for each item includes ItemsIsSelectable and ItemIsEnabled (default).

My itemDelegate contains:

Rectangle {
                   color: styleData.isSelected ? "red" : "black"

I added a selection to the treeview:

ItemSelectionModel {
          id: treeViewSelectionModel
          objectName: "treeViewSelectionModel"
          model: treemodel
          onCurrentChanged:{console.log("Selection - current changed from ",previous, " to ", current)}
      }

Which correctly prints out the new/previous selection. So it appears the item is being selected, but not changing color (the isSelected never changes for the item). Can someone explain why?

Problem is inconsistency in how QML names its methods. Some are "isSelected" (eg ROW), or "isExpanded" (ITEM), but item uses "selected" instead of "isSelected"
