Launch python toolbox from toolbar: can it be done?

deleted-user-zpcJw1u0IXiO

I need to put a button on a toolbar to launch my new python toolbox tool that maps condos. I have found this to be impossible, and am hoping for help...

I've tried building an add-in to launch the pyt, but in testing it I get a pop-up error "Failed to open toolbox Condos.pyt". Perhaps this means add-ins simply do not support python toolboxes, or maybe I've incorrectly specified the path in the add-in's onClick def:

toolboxPath = os.path.join(os.path.dirname(__file__), toolboxName + ".pyt")

The reason I'm uncertain about the path is that the pyt is in "My Toolboxes", and I don't know whether this code actually points there (I'm very new to python). Or maybe a pyt is merely incompatible here, because the example code has ".tbx" in the above line. Any ideas?

To re-write my pyt as a regular python script in a tbx and set up params that way has certainly occurred to me and would probably work, but would be a huge disappointment given the time invested in the pyt that works so nicely. How can I launch from a toolbar button the CondoBuilderTool of Condos.pyt? Is that even possible? Please help me with some suggestions here. How can I resolve this?

Thanks in advance,
Justin

The .pyt files need to be placed in the install folder of the python add-in, and the makeaddin.py file needs to be re-run.

After that, you can then re-install the add-in by double clicking on the file.

Also, ensure that you close and restart arcmap or catalog.

Works like a charm now. I've learned a lot today

. Thanks so much, Andrew!

Also, ensure that the .pyt is in the add-in file. You can check that by renaming the extension .zip and examining the contents.

Thank you Andrew. I have updated Tools_addin.py as you instructed, as follows:

    def onClick(self):

        # name of toolbox
        toolboxName = "Condos"

        # name of tool to be executed (the class in Condos.pyt) 
        toolName = "CondoTool"

        # create string with path to toolbox
        relPath = os.path.dirname(__file__)
        pyt = relPath + os.sep + toolboxName + ".pyt"

        # call geoprocessing tool
        pythonaddins.GPToolDialog(pyt, toolName)

        pass

Yes, I did check the add-in file and did NOT find the .pyt anywhere inside. The file contains two subfolders, so can I just insert the .pyt to the file as I would into a zip? If no, please explain the proper method. If yes, should the Install subfolder be the destination? Further, what more should I do to ensure the .pyt is included when I share the add-in (I feel I'm updating here the installed add-in, not the actual installer--please correct me if I'm wrong).

You need to call the class name for a .pyt. So I have a python tool called 'Tool', so I pass in Tool to the name parameter.

        relPath = os.path.dirname(__file__)
        pyt = relPath + os.sep + "customToolbox.pyt"
        pythonaddins.GPToolDialog(pyt, "Tool") # Tool is the class name

Also, ensure that the .pyt is in the add-in file. You can check that by renaming the extension .zip and examining the contents.
