Python toolbox: how to set default values

AlbertoLaurenti — Thu, 11 Sep 2014 15:01:55 GMT

I need to set a default value for a Boolean parameter in my Python toolbox, but I didn't found any documentation about that. I'm able to do it using the custom toolbox wizard, but I found nothing on how to do the same in a python toolbox.

Any idea?

Thanks

Here is a small sample of adding a boolean value and adding a default value to it.

        booleanTest = arcpy.Parameter(
            displayName="boolTest",
            name="booleanTest",
            datatype="GPBoolean",
            parameterType="Optional",
            direction="Input")


        booleanTest.value = "true"

Does this help?

Why not do it through the interface? For example, you can right click on a toolbox script and access its properties etc, then bring up the dialog which allows you to establish the relationship etc between your input parameters and the script. This image is a visual of establishing a Folder as an input parameter.

Hi Dan,

I don't think that functionality is available with python toolboxes but rather script tools only.
