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:

        </Toolbars>

        <Menu caption="Category" category="WTF" id="WTF_addin.cat_menu" isRootMenu="false" isShortcutMenu="false" separator="false"><Items><Button refID="WTF_addin.fish_button" /></Items></Menu>  
        </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.
