listItems refusing to reset selectedItem when cleared

perryK67ZX — Tue, 31 Oct 2023 10:37:29 GMT

I have several inputs that use listItems (namely a Dropdown and a ButtonRow) in my plugin that need to update values depending on other inputs. Unfortunately, when I try to reset them, I can never get it to deselect the currently selected item. I've tried calling deleteMe(), setting isSelected=False, calling clear() on the parent listItems, and so forth, but the listItem.selectedItem is still there, and still valid too. Am I doing something wrong? Is this a known bug? What am I missing here?

Hi @perryK67ZX -San.

This has been my experience as well.

It's not a pretty solution, but when I set up ListItems, I first assigned an item that means unselected and made it selected.

# Fusion360API Python script import traceback import adsk import adsk.core as core import random _app: core.Application = None _ui: core.UserInterface = None _handlers = [] CMD_INFO = { 'id': 'kantoku_test', 'name': 'test', 'tooltip': 'test' } _dropIpt: core.DropDownCommandInput = None _buttonIpt: core.BoolValueCommandInput = None class MyCommandCreatedHandler(core.CommandCreatedEventHandler): def __init__(self): super().__init__() def notify(self, args: core.CommandCreatedEventArgs): core.Application.get().log(args.firingEvent.name) try: global _handlers cmd: core.Command = core.Command.cast(args.command) inputs: core.CommandInputs = cmd.commandInputs onDestroy = MyCommandDestroyHandler() cmd.destroy.add(onDestroy) _handlers.append(onDestroy) onInputChanged = MyInputChangedHandler() cmd.inputChanged.add(onInputChanged) _handlers.append(onInputChanged) global _buttonIpt _buttonIpt = inputs.addBoolValueInput( "_buttonIptId", "Change Items", False, ) global _dropIpt _dropIpt = inputs.addDropDownCommandInput( "_dropIptId", "Select Item", core.DropDownStyles.TextListDropDownStyle, ) reset_items(_dropIpt) except: _ui.messageBox('Failed:\n{}'.format(traceback.format_exc())) class MyInputChangedHandler(core.InputChangedEventHandler): def __init__(self): super().__init__() def notify(self, args: core.InputChangedEventArgs): global _buttonIpt if args.input != _buttonIpt: return global _dropIpt reset_items(_dropIpt) class MyCommandDestroyHandler(core.CommandEventHandler): def __init__(self): super().__init__() def notify(self, args: core.CommandEventArgs): core.Application.get().log(args.firingEvent.name) adsk.terminate() def reset_items( dropIpt: core.DropDownCommandInput ) -> None: listItems: core.ListItems = dropIpt.listItems listItems.clear() listItems.add("Plase Select Item", True) numbers = [random.randint(1, 100) for _ in range(5)] for num in numbers: listItems.add(str(num), False) def run(context): try: global _app, _ui _app = core.Application.get() _ui = _app.userInterface cmdDef: core.CommandDefinition = _ui.commandDefinitions.itemById( CMD_INFO['id'] ) if not cmdDef: cmdDef = _ui.commandDefinitions.addButtonDefinition( CMD_INFO['id'], CMD_INFO['name'], CMD_INFO['tooltip'] ) global _handlers onCommandCreated = MyCommandCreatedHandler() cmdDef.commandCreated.add(onCommandCreated) _handlers.append(onCommandCreated) cmdDef.execute() adsk.autoTerminate(False) except: if _ui: _ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

When I click on the "Change Items" button, the drop-down list changes and the "Plase Select Item" becomes selected.
