I originally wrote this as a python add-in but I could really use some type of GUI or user interface. Since Tkinter and wx are not supported nor stable when used inside ArcMap I am trying to either build the entire functionality in a python toolbox or python add-in although it looks like I will have to use a combination of both.
All I want is to be able to do is loop through a directory and return a list of folders within that directory. These folders all contain different layer files(*.lyr)
When the user would choose a folder, a list of values would be presented to the user in something like a listbox or pick list. After user selects layer it adds the layer to the TOC.
How can I get the code below to return a list in a python toolbox and present it to the end user as a drop down or combobox.
I would have thought there would have been some type of parameter to have a list presented to the end user but I cannot seem to find one that will work for this scenario.
wrkspc = '//someserver/GIS/Layers/'
folders = 
for dirpath, dirnames, filenames in arcpy.da.Walk(wrkspc,topdown=True):
if '.' not in str(dirpath):
folder = str(os.path.basename(dirpath))
