Hello,
I am attempting my very first python add in. what I would like it to do is look at a feature class, look through the town field. when the user selects a town I want the next combo box to populate with the LABELTEXT field with all of the values in that town and when a LABELTEXT is selected zoom to that bad boy.
I dont know how to get the town return into the ComboClass2 class or build the query to filter based on the town result
class ComboBoxClass1(object):
"""Implementation for addin2_addin.combobox (ComboBox)"""
def __init__(self):
self.editable = True
self.enabled = True
self.dropdownWidth = 'WWWWWWWWWWWWWWWW'
self.width = 'WWWWWWWWWWWWWWWW'
def onSelChange(self, selection):
layer = arcpy.mapping.ListLayers(mxd, "block_cards", df)[0]
a = arcpy.SelectLayerByAttribute_management(layer, "NEW_SELECTION", "town = '" + selection + "'")
return a
df.extent = layer.getSelectedExtent()
arcpy.RefreshActiveView()
def onFocus(self, focused):
global mxd
mxd = arcpy.mapping.MapDocument('current')
global df
df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]
layer = arcpy.mapping.ListLayers(mxd, "block_cards", df)[0]
arcpy.SelectLayerByAttribute_management(layer, "CLEAR_SELECTION")
self.items = []
values = [row[0] for row in arcpy.da.SearchCursor(layer, ["town"])]
for uniqueVal in sorted(set(values)):
self.items.append(uniqueVal)
class ComboBoxClass2(object):
"""Implementation for addin2_addin.combobox (ComboBox)"""
def __init__(self):
self.editable = True
self.enabled = True
self.dropdownWidth = 'WWWWWW'
self.width = 'WWWWWW'
def onSelChange(self, selection):
layer = arcpy.mapping.ListLayers(mxd, "block_cards", df)[0]
arcpy.SelectLayerByAttribute_management(layer, "NEW_SELECTION", "town = '" + ComboBoxClass1.onSelChange() + "' AND LABELTEXT = '" + selection + "'" )
df.extent = layer.getSelectedExtent()
arcpy.RefreshActiveView()
def onFocus(self, focused):
global mxd
mxd = arcpy.mapping.MapDocument('current')
global df
df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]
layer = arcpy.mapping.ListLayers(mxd, "block_cards", df)[0]
arcpy.SelectLayerByAttribute_management(layer, "CLEAR_SELECTION")
self.items = []
values = [row[0] for row in arcpy.da.SearchCursor(layer, ["LABELTEXT"])]
for uniqueVal in sorted(set(values)):
self.items.append(uniqueVal)
