_tkinter.TclError: Layout PViewStyle not found

I am having trouble defining a Style for my Treeview widget.

newT=ttk.Style() 
newT.configure('PViewStyle', rowheight=100) 
PatrolView = ttk.Treeview(PatrolOverview,style='PViewStyle')

but this yields 

_tkinter.TclError: Layout PViewStyle not found
Solution

  • I get same error :). The problem is that name style must be end to correct name style in tkinter

    Widget class Style name
     Button TButton
    Checkbutton TCheckbutton
    Combobox TCombobox
    Entry TEntry
    ...
    Treeview Treeview (not TTreview!)

    In your case you need to name your style as PViewStyle.Treeview

    Change our code to:

    newT=ttk.Style() 
newT.configure('PViewStyle.Treeview', rowheight=100) 
PatrolView = ttk.Treeview(PatrolOverview,style='PViewStyle.Treeview')
