The minimal sample here has a runtime style selector, for any other users who might want to see a d demo. StyleText.zip (8.4 KB)
Issue 1:
The style resource file includes some extra properties which should not be in a style:
ex: from a listbox header: "Text":"Item List"
Can these be removed from the next release, I know the manual fix.
Issue 2:
The second issue is with showlines= true from the treeview used by the listbox.
When you apply a theme, the lines become visible.
Can inheritance be blocked or redefined?
After thinking / looking further on this, the question might be should the treeview style actually control the ShowLines property? The style should control the color and stroke, but not the visibility?
