Refreshing combo box in Python add-in of ArcPy?

Question

I've got an add-in with a combo box and want to refresh the list in the combo box after an event in one of the other tools in the same add-in toolbar.

Can I call the combo box somehow to refresh it outside of the object's onSelChange event?

• user17971: Can I see your code solution please, I have the same problem. I need to link a couple of combos. thank you and best regards!

Answer 1

Finally managed to sort this one out. I managed to do that by adding a method in the combo box class, initiated them in the button class (where I wanted to refresh the combo box from) and then called the methods from within the button class.

import arcpy
import pythonaddins
cboSetup1 = None
cboSetup2 = None
class btn1(object):
 """Implementation for Class_addin.button (Button)"""
 def __init__(self):
 self.enabled = True
 self.checked = False
 def onClick(self):
 combo1 = cbobox1()
 combo1.btnPopulate()
 combo2 = cbobox2()
 combo2.btnPopulate()
class cbobox1(object): 
 """Implementation for Class_addin.combobox (ComboBox)"""
 def __init__(self):
 self.editable = True
 self.enabled = True
 self.dropdownWidth = 'WWWWWW'
 self.width = 'WWWWWW'
 def onFocus(self, focused):
 self.items = cboSetup1
 def btnPopulate(self):
 mxd = arcpy.mapping.MapDocument("CURRENT")
 self.items = []
 for layer in arcpy.mapping.ListLayers(mxd):
 self.items.append(layer.name)
 global cboSetup1
 cboSetup1 = self.items
class cbobox2(object):
 """Implementation for Class_addin.combobox_1 (ComboBox)"""
 def __init__(self):
 self.editable = True
 self.enabled = True
 self.dropdownWidth = 'WWWWWW'
 self.width = 'WWWWWW'
 def onFocus(self, focused):
 self.items = cboSetup2
 def btnPopulate(self):
 mxd = arcpy.mapping.MapDocument("CURRENT")
 self.items = []
 for layer in arcpy.mapping.ListLayers(mxd):
 self.items.append(layer.name)
 global cboSetup2
 cboSetup2 = self.items
