Python Add-In Button Issues

CoyPotts1

Rebecca Strauch

I'm tagging Rebecca because of the conversation here: Custom toolbar that contains Python Scripts

I have been playing with the Python Add-In Wizard, and I have created a toolbar with some menus and buttons. I am having trouble getting the buttons to work, though. I've followed Rebecca's instructions (here: Python add-ins vs. .NET add-ins?), as well as the attached PDF to try and use an existing python script within my toolbox, but the button just shows up as missing when I install the add-in and run ArcMap. I've even tried pasting the entire code from the script directly into the onClick function, and that just does the same thing.

Is this a common problem? Is this indicative of a common issue, or could it be a vague error that would be harder to diagnose...? I read somewhere that the missing designation could mean that there is some sort of syntax error in the code, but the scripts work on their own...just not whenever I try to associate them with a button on the custom add-in toolbar.

Thanks you!

Ha, ya some things are head scratchers. Make sure to come back and summary if you find an answer. MArk any of the above if they were helpful, and then mark the questions a assumed answered if none was a complete answer.

Good luck. I'll still try to get you a sample later today if you haven't resolved it yet....but I'm knee deep into getting my last script to do all I want (close, but not quite).

The mismatching is due to me creating a whole new project thinking that there may have been an error somewhere down the line that I didn't notice. I created a whole new project so that the *_addin.py file would be default (thinking that the default file would eliminate any syntax errors). I've been using the MessageBox example as shown above just to test, but the button still shows as missing even if I don't add the MessageBox function. I can generate a completely default *_addin.py file, create/install the add-in, and ArcMap still shows a missing button. There can't be any syntax errors if I haven't even typed anything into the file...something has to give here lol.

Thank you for your recommendations and assistance as well. I appreciate the efforts.

CoyPotts1

Yeah, I actually just contacted support via email about 10 minutes ago lol. In this instance, if it's one of the two that you have experienced the problem in, my bet is an environment variable issue.

After my scripts weren't working yesterday, all I have been testing with now is the very basic MessageBox that I pasted in a response above. Everything else in the *_addin.py file is the default script that is generated once you create the add-in project.

Thanks for your recommendations, though! I appreciate it.

I have addins with both version 10.1 and 10.3 in the config.xml, so I don't think that is an issue.

I did notice though that your id= values don't match the "class" names in the original <project>_addin.py file

I think ButtonClass1 is the default, and in your _addin.py file you show map_to_kml You may have more than that that isn't showing. I have those two items batch in my addins.

Also, just fyi, most have mine have been for Catalog, not ArcMap, so there may be things I haven't run into.

Try to see if making thing match up helps.

Well, that's good. Now you can write arcpy scripts that run outside of ArcMap.

I'd suggest calling ESRI tech support. Without being able to remote into your computer, it's hard to troubleshoot.

However, I've personally only seen the Missing icons in two instances:

There was a syntax error in the script
The Environment Variables weren't setup correctly

Good luck!

CoyPotts1

I'm replying to the original post as I am referencing multiple suggestions here.

Ian Broad

Doing what you suggested above did indeed allow me to pull "python" and "import" through the command window, but it didn't fix the issue I am having with the add-in.

I restarted my machine, re-created/re-installed an add-in with one toolbar that had one button, added a MessageBox command to the onClick function...and I still get a button that says missing whenever I open up ArcMap.

Rebecca Strauch

I was looking at my XML config file, and I noticed that my target version was set to 10.1. Whenever I was working in the 10.2.2 yesterday, my target version was 10.2, but now that I'm in 10.3.1, my target version says 10.1. Very confusing. I changed the 10.1 to 10.3.1, and in doing so, the add-in will not show up in ArcMap when I open the document. It says it installed correctly, but it just doesn't show up. I changed it back to 10.1 and it shows up again with a missing button.

Is there some sort of issue with that version number that could be causing problems?

Thanks for the suggestions, Rebecca.

Modifying the toolbox to have no spaces, as well as moving it to the top of the script, didn't work. On that note, however, shouldn't the tool still run when I use the actual code instead of referencing a script file?

I have tried with double and single quotes. Neither has made a difference, so I'm thinking it's the error is related to something else.

Just as a test I re-saved the project so that the python script was back to the default that is auto-created. I re-created the add-in and installed it again. The buttons still show up as missing. Why would they show up as missing if I haven't modified the original python add-in script...? I would have thought that they would simply show up and do nothing as apposed to showing as missing.

*EDIT*

I went back and instead of leaving "pass" after each onClick, I added a simple MessageBox. The below code still gives buttons that show as missing.

import arcpy
import pythonaddins

class map_to_kml(object):
    """Implementation for map_to_kml.button (Button)"""
    def __init__(self):
        self.enabled = True
        self.checked = False
    def onClick(self):
        pythonaddins.MessageBox("This is a message box.", "Message Box", 0)

class osp_export(object):
    """Implementation for osp_export.button (Button)"""
    def __init__(self):
        self.enabled = True
        self.checked = False
    def onClick(self):
        pythonaddins.MessageBox("This is a message box.", "Message Box", 1)

The tool name in the pythonaddins.GPToolDialog line definitely shouldn't have spaces. Make sure you are taking the Name and not the Label

Also, for what it's work, I've pulled the ToolPath line to the top of the _addin.py file so I don't have to repeat it, for example.

import arcpy
import pythonaddins
import os
relPath = os.path.dirname(__file__)
toolPath = relPath + r"\CheckAndFixLinks.tbx"


class btnGDBInventory(object):
    """Implementation for GDBInventory_addin.button (Button)"""
    def __init__(self):
        self.enabled = True
        self.checked = False
    def onClick(self):
        pythonaddins.GPToolDialog(toolPath, "ListFGDBsize")

class btnFCInventory(object):
    """Implementation for FCInventory_addin.button (Button)"""
    def __init__(self):
        self.enabled = True
        self.checked = False
    def onClick(self):
        pythonaddins.GPToolDialog(toolPath, "FCInventoryReport")

Does your script run ok outside the addin? That should be checked first of course. you answered that in the OP.

also, try double quotes instead of single toolpath and tools. Shouldn't matter, but worth a try.

This is the python file with the code within it. Again, it is a direct copy from the working script that we use daily, so I don't think it is a syntax error, unless there is some functionality that needs to change between stand-alone scripts and add-ins.

import arcpy
import pythonaddins
import os
import arcpy.mapping as map
from arcpy import env
mxd = map.MapDocument("CURRENT")

class map_to_kml(object):
    """Implementation for map_to_kml.button (Button)"""
    def __init__(self):
        self.enabled = True
        self.checked = False
    def onClick(self):

        # Apply Symbology Layer file  

        # Set local variables
        inputLayer = r'Entire Coverage Area\Fiber Segments'   
        symbologyLayer = r'\\extenet.local\dfs\Network-Planning-GIS\1)Documentation\ArcGIS_Files\4)Symbology_Layer_Files\Fiber Segments (KMZ).lyr'  

        # Execute the ApplySymbologyFromLayer tool
        arcpy.ApplySymbologyFromLayer_management (inputLayer, symbologyLayer)

        # Save the map  
        mxd.save()

        # Map to KML tool  

        # Set local variables  
        df = arcpy.mapping.ListDataFrames(mxd)[0].name
        mapName = str(mxd.filePath).split('\\')[-1:][0][:-4]
        filepath1 = str(mxd.filePath)[:79] + mapName + "/6)Deliverables/"
        version = arcpy.GetParameterAsText(0)
        outputKML = filepath1 + mapName + " " + version + '.kmz'
        extent = 'Same as layer Fiber Segments'  

        # Execute MapToKML tool 
        arcpy.MapToKML_conversion(mxd.filePath, df, outputKML, '', '', '', extent,'', '', '')


        # Apply Symbology Layer file

        # Set local variables  
        inputLayer = r'Entire Coverage Area\Fiber Segments'    
        symbologyLayer = r'\\extenet.local\dfs\Network-Planning-GIS\1)Documentation\ArcGIS_Files\4)Symbology_Layer_Files\Fiber Segments.lyr'  

        # Execute ApplySymbologyFromLayer tool
        arcpy.ApplySymbologyFromLayer_management (inputLayer, symbologyLayer)

Here is the python file just referencing the existing script:

import arcpy
import pythonaddins
import os
relPath = os.path.dirname(__file__)

class map_to_kml(object):
    """Implementation for map_to_kml.button (Button)"""
    def __init__(self):
        self.enabled = True
        self.checked = False
    def onClick(self):
        toolPath = relPath + r'\ExteNet Systems Toolset.tbx'
        pythonaddins.GPToolDialog(toolPath, 'Map to KML1')

I made sure that the referenced tool is using relative path names, and the toolbox is in the install folder for the add-in. I tried this with just about every variation of the tool name I could think of. I used the no space version, I used the ".py" afterwards. I also tried the os.startfile() method with a direct link to the tool instead of concatenated as shown above.

Hi Coy,

If you are getting the "null-missing" for you button, in your <project>_addin.py file, check to make sure your quotes are balanced, and the same type. I had a set of striat quotes on one side some text, and the curly type on the other side, and that gave me an issue on the toolbar I'm currently work on. Drove me nuts for a while.

If you can post that file (see Posting Code blocks in the new GeoNet ) , it may help to see if there is anything obvious. The missing button, per esri support, means syntax error....pretty generic. But more sets of eyes might help.
