How to set the highlighted

[johnken]

Can anyone advise how to set the highlighted of an icon in the Header bar widget please?

The blog post shows how to change the name or icon but I can't see from the API docs or the post how to get at the highlighted property of an icon in the header bar widget.

I am trying to use a header bar icon button to show/hide editing buttons on the card and I want the icon button to be a toggle switch. I could do it with a text button but that's not the style of the app.

Many thanks for any assistance provided.

Setting the hilitedItem is possible in the navbar widget, not in the headerbar widget.
In the navbar widget hiliting changes the color and the property hilitedItem.
In the headerbar widget hiliting changes the icon/iconText (use property hilitedItemIcons), the icons/iconTexts use always the hiliteColor.
