Disabling Toolbar in Layout View using Python AddIn of ArcPy?

Question

I'm trying to disable a toolbar with nested menus and buttons when an mxd is in layout view, but it's not working. I also get no output in the ArcGIS python window when I switch to layout view.

Anyone have any ideas?

Using: ArcGIS 10.2.2, Python 2.7

Code:

import arcpy 
import pythonaddins 
class FishButton(object): 
 """Implementation for WTF_addin.fish_button (Button)""" 
 def __init__(self): 
 self.enabled = True 
## self.checked = False 
 def onClick(self): 
 self.mxd = arcpy.mapping.MapDocument('current') 
## layer = r'\\msds.wv.de\dfsroot\HV\GROUP\Gis\DATEN\wvdat\Querbauwerke\Fischaufstieg.lyr' 
 layer = r'G:\Gis\DATEN\wvdat\Querbauwerke\Fischaufstieg.lyr' 
 activeDataFrame = self.mxd.activeView 
 df = arcpy.mapping.ListDataFrames(self.mxd, activeDataFrame)[0] 
 if arcpy.Exists(layer): 
 layerToAdd = arcpy.mapping.Layer(layer) 
 arcpy.mapping.AddLayer(df, layerToAdd, 'TOP') 
 else: 
 warningButton = pythonaddins.MessageBox("Die Datei ist nicht verfugbar.\nBitte kontaktieren Sie die GIS Abteilung.", "Datei nicht verfugbar", 0) 
 pass 
class changeToolState(object): 
 """Implementation for WTF_addin.disable (Extension)""" 
 def __init__(self): 
 # For performance considerations, please remove all unused methods in this class. 
 self.enabled = True 
 def activeViewChanged(self): 
 mxd = arcpy.mapping.MapDocument('current') 
 active_view = mxd.activeView 
 if active_view == 'PAGE_LAYOUT': 
 WTF_toolbar.enabled = False 
 print 'button has been disabled...' 
 else: 
 WTF_toolbar.enabled = True 
 print 'button re-enabled...' 
 arcpy.RefreshActiveView() 
 return 

And the corresponding config.xml:

 </Menus> 
 </ArcMap></AddIn></ESRI.Configuration>

Based off your code, it sounds like you're trying to disable a button rather than an entire toolbar.

Instead of WTF_toolbar.enabled = False do fish_button.enabled = False to disable the button. Same goes for WTF_toolbar.enabled = True.

There is more info in the help for Managing the state of Python add-in types

• user151631: Thanks -- trying to disable the entire toolbar. The print statements were copied in from somewhere else.
• José Gabriel: I am trying this. Did you got it working? from link that @freshmints provided: "...The enabled property is available for buttons, tools, and combo boxes." nothing about toolbars and it is not workin for my toolbar.
