Multiple Parameters for Python Addin?

MikeMacRae — Mon, 28 Apr 2014 20:50:16 GMT

I'm running ArcGIS 10.1 and I'm creating a Python Addin. I'm am wondering if we can have multiple parameters for a python addin tool/button/combobox?

This is what I want to do. I want to create a button that takes 2 parameters the user will choose and zoom to an area of interest.

After the user chooses an item, they will manually enter a number (this is a site number. Both of the SDE feature classes have a field called SITE_NUMBER).

So, now they have chosen a record in one of the 2 SDE feature classes.

When they have entered these 2 parameters, I would have them click on a button and the map will zomm to the area.

I can get the coding down, but I'm not sure if I can set 2 parameters like this?

This sounds like the job for a geoprocessing tool.

You could just associate the button's onClick with a GPToolDialog call.

I'm giving that a try. I wanted to see how this works, so I just tried to use the example on the page you provided and tried to create a button that opens the 'Intersect' tool:

import arcpy
import pythonaddins

class OpenGPTool(object):
    """Implementation for Test_Addin_Button_addin.button (Button)"""
    def __init__(self):
        self.enabled = True
        self.checked = False
    def onClick(self):
        pythonaddins.GPToolDialog(r'path to ArcGIS Install\ArcGIS\Desktop10.1\ArcToolbox\Toolboxes\Analysis Tools.tbx', 'Intersect')

This isn't working. I'm getting the red circle "Missing" icon when I try to open my addin. I thought it might be the path to the tool because it sits in a toolset, so I tried:

pythonaddins.GPToolDialog(r'path to ArcGIS Install\ArcGIS\Desktop10.1\ArcToolbox\Toolboxes\Analysis Tools.tbx\Overlay', 'Intersect'

pythonaddins.GPToolDialog(r'path to ArcGIS Install\ArcGIS\Desktop10.1\ArcToolbox\Toolboxes\Analysis Tools.tbx', 'Overlay\Intersect'

And nothing seems to work.

You can set any number of variables / parameters.

First, set a variable to hold each parameter at the head of the ~_addin.py
just after your imports

dataType = listOfTypes
dataField = listOfFields
dataDate = listOfDates
dataList = listOfChoices

theType = 'none'
theField = 'none'
theDate = 'none'
theChoice = 'none'

now declare each of the variables global inside each class where you want to set or use them.
for example:

class ComboBoxClass_DataType(object):
    """Select the data TYPE            """
    def __init__(self):
        global dataType
        self.items = dataType
        self.editable = True
        self.enabled = True
        self.dropdownWidth = '%s' % ('W' * 12)
        self.width = '%s' % ('W' * 12)
        
    def onSelChange(self, selection):
        global theType
        theType = selection

Then, in the class behind the 'go' button, access that variable and
any others the user sets in other wigits

class ButtonClass_LoadData(object):
    """Implementation for DataBrowser_LoadData.button (Button)
        LOADS the data into the current mxd     """
    def __init__(self):
        self.enabled = True
        self.checked = False
    def onClick(self):
        global theType
        global theField
        global theDate
        global theChoice
        result = LayerFinder.loadLayerToMxd(theType, 
                                                           theField, 
                                                           theDate, 
                                                           theChoice)

Dynamically preloading the input lists is an enhancement......
