I have a toolbar which enables a second and third combobox when a selection is made on the previous. I would like to add a button to 'reset' the toolbar. Basically reload the toolbar to it's original load state. Any thoughts?
Code follows:
import arcpy
import pythonaddins
layer = arcpy.mapping.ListLayers(arcpy.mapping.MapDocument("CURRENT"))[0]
arcpy.SelectLayerByAttribute_management(layer,"CLEAR_SELECTION")
arcpy.RefreshActiveView()
class Survey(object):
"""Implementation for DatabaseSearch_addin.combobox1 (ComboBox)"""
def __init__(self):
#in the initialisation of the addin
self.items = []
self.editable = True
self.enabled = True
self.dropdownWidth = 'WWWWWW'
self.width = 'WWWWWW'
#set the map document reference
mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd)[0]
layer = arcpy.mapping.ListLayers(mxd)[0]
# check if the layer exists
if layer:
#create a column name variable for the search cursor parameters
column_BlockNo = "L1SURNAM"
sc = arcpy.SearchCursor(layer,""""L1SURNAM" <> ' '""","",column_BlockNo,column_BlockNo)
#Due to the multiple values stored in the attribute table a dictionary had to be used
#Create a dictionary
dictionary = {}
#for loop to iterate through the attribute tables getting the values for the column
for row in sc:
#set the value as the row value in the column block number
val = row.getValue(column_BlockNo)
#the nature of dictionaries does not allow for duplicates thus handling the redundant block numbers in the data table for use in the combobox
dictionary[val] = val
#create a list of items for the dictionary's unique keys to be written to
Items = []
#for loop to iterate through the keys in the dictionary
for key in dictionary.iterkeys():
#append the key values to the list Items
Items.append(key)
#append the list of keys to the Blocknumber(self) item list

#sort keys in ascending numeric order
self.items.sort()
