Python Add-In Combobox will not populate

JohnKing

Hi all,

I'm trying to create a simple add-in combo box using the new python interface. I have read the ESRI help on creating an add in project (http://resources.arcgis.com/en/help/main/10.1/index.html#/project/014p00000022000000/) as well as creating an add in combo box (http://resources.arcgis.com/en/help/main/10.1/index.html#/combo_box/014p00000028000000/).

I am having trouble populating the combo box from a list of values that I pass to the __init__ class within the install file.

Here is my entire script:

import arcpy
import pythonaddins

class ComboBoxClass1(object):
    """Implementation for Project Map_addin.combobox (ComboBox)"""
    def __init__(self):
        self.items = ["Project 1", "Project 2", "Project 3", "Project 4"]
        self.editable = False
        self.enabled = True
        self.dropdownWidth = 'WWWWWWWWW'
        self.width = 'WWWWWWWWWWWW'
        self.refresh()

    def onSelChange(self, selection):
        pass
    def onEditChange(self, text):
        pass
    def onFocus(self, focused):
        pass
    def onEnter(self):
        pass
    def refresh(self):
        pass

I have tried a number of different things to get the drop-down to populate. None have worked.

Any suggestions would be great

Thanks for the quick responses.

AMJSkinn3: All Arc applications were closed when the add-in was installed. To make sure I uninstalled the add in, recreated the project folder, compiled, and re-installed the add-in. Also, neither the python window nor the results window have any errors to report. When I added the toolbar to ArcMap, the combo box says "[Missing]".

For a quick explanation to what I'm trying to accomplish.. I'd like to select a project name from the combo box. The project name selected will direct a python script to grab specific layers on file with which it will build a project map with correct Data Frame name and Spatial Reference.

I'm trying to solve this issue with the simplest example possible to make sure it is do-able.

What is the name of the folder directory your add-in is stored in?  It cannot contain spaces.  For example, if the folder directory is called 'Combo Box', you will receive the 'Missing' icon on your toolbar.  Recreate the add-in and make sure there are no spaces in the directory.
