Allplan Forum: Programatically creating/changing parameters

Hello!

What I want to do:

Let the user import an Excel file
Extract the available worksheets
List them in the Python part, where the user can select the worksheets that he wants to work with (each worksheet has a checkbox)

My problem: I am successfully allowing the user to import the file and retrieve the worksheets, but I am not able to list all the worksheets.
Right now I am trying to do it like this:
Creating the parameter:

    <Parameter>
        <Name>SelectedWorksheets</Name>
        <Text>Worksheet1,Worksheet2</Text>
        <Value>False|False</Value>
        <ValueType>namedtuple(CheckBox,CheckBox)</ValueType>
        <NamedTuple>
            <TypeName>WorksheetSelection</TypeName>
            <FieldNames>Worksheet1,Worksheet2</FieldNames>
        </NamedTuple>
    </Parameter>

Modifying the parameter:

        props = ctrl_prop_util.control_props
        # Assigning worksheet names to props[':SelectedWorksheets'][0].text
        props[':SelectedWorksheets'][0].text = '|'.join(worksheet_names)

But when I try to change the value string, I get the error that value_str does not have any setters. This is how I am trying to change it:

        props[':SelectedWorksheets'][0].value_str = '|'.join(['False'] * len(worksheet_names))

Is there another way to do this?

Another option would be to dynamically create the parameter (creating a checkbox parameter for each worksheet), but I did not manage to do this and I also could not find anything in the manual...

Hi,

Have you try with "_replace" ?

Example :

<Parameter>
	<Name>StirrupList</Name>
	<Text>,Espacement,Distance</Text>
	<Value>[images\ParamB.png|120|450;
			images\ParamC.png|120|450]
	</Value>
	<ValueType>namedtuple(Picture,Length,Length,Separator)</ValueType>
	<NamedTuple>
		<TypeName>Stirrup</TypeName>
		<FieldNames>Picture,Spacing,Length,Separator</FieldNames>
	</NamedTuple>
	<MinValue>,50,,</MinValue>
	<MaxValue>,360,,</MaxValue>
	<Enable>,,False</Enable>
</Parameter>

stirrup_list    = build_ele.StirrupList.value
stirrup_list[0] = stirrup_list[0]._replace(Spacing = B_stirrup_spacing)

Best
Christophe

I have now found a solution, but it still uses some 'private' methods, so I guess it is not the best way to do this:

from typing import List
from BuildingElement import BuildingElement
from ControlProperties import ControlProperties

def appendToNamedTuple(id_name: str,
            selectedWorksheetsProps: ControlProperties,
            worksheet_names:  List[str],
            type:   str,
            build_ele:        BuildingElement):
        # assign the names of the worksheet to the text and divide them with a |, so that each checkbox has a their 'title'
        selectedWorksheetsProps._ControlProperties__text = '|'.join(worksheet_names)
        # for each worksheet append the name with an id to the named tuple definition (in my case worksheet0, worksheet1, etc.)
        for idx in enumerate(worksheet_names):
            name = id_name
            name += str(idx)
            build_ele.SelectedWorksheets.named_tuple_def.field_names.append(name)
            # assign the init value. in my case  0 for false
            build_ele.SelectedWorksheets._ParameterProperty__value += (0,)
        # define what type the thing has, in my case it is CheckBox, but can be Integer, ComboBox, ...
        initial_value = 'namedtuple('
        checkboxes = (',' + type) * len(worksheet_names)
        checkboxes = checkboxes[1:]
        build_ele.SelectedWorksheets.value_type = initial_value + checkboxes + ')'
