How to add a button in geoprocessing tool?

BittersDaniel — Mon, 14 Oct 2024 20:36:42 GMT

I was wondering if there is a way to add a button to a geoprocessing tool to validate and have a pop-up message before the user runs the tool.

For example, the Add Join tool has a button like this. I couldn't find a way to add a button though and am wondering if I am missing something. Thanks!

you can validate a tool

Here's a simple example tool that should work using @DanPatterson 's checkbox button idea. I use checkbox buttons this way all the time:

import arcpy class ValidateButtonExample: """Generates frames for a given layout""" def __init__(self) -> None: self.category = "Example" self.label = "Button Parameter" self.description = "A Button Parameter Example" return def getParameterInfo(self): validate_button = arcpy.Parameter( name="validate_button", displayName="Validate", direction="Input", datatype="GPBoolean", parameterType="Required", ) validate_button.value = False return [validate_button] def updateParameters(self, parameters:list[arcpy.Parameter], messages:list) -> None: """Modify the values and properties of parameters before internal validation is performed.""" params = named_params(parameters) if params.validate_button.value: self.validate(parameters, messages) params.validate_button.value = False return def validate(self, parameters:list[arcpy.Parameter], messages:list) -> None: """This is run when someone clicks the validate checkbox""" parameters = named_params(parameters) # Implement your validation logic here return def execute(self, parameters:list[arcpy.Parameter], messages:list) -> None: """This is run when someone clicks the Run button""" # Implement your tool logic here return def named_params(parameters:list[arcpy.Parameter]) -> object: """ Return an object with named parameters """ params = object() for param in parameters: setattr(params, param.name, param) return params

Thanks for that example, I might try to implement something like that.

One scenario I am concerned about is if a user starts checking and unchecking the box within seconds, which would probably interrupt any geoprocessing functions that need to happen in the validation and could confuse the tool.
