onSlection event

[JanNavratil]

Hello,

I'm trying to create small addin to get the velues on select of random things in the graphic windows.
I was thinking that this should be ok but, I'm not getting anything when I select entity.

# Event handler for the select event.
class MySelectHandler(adsk.core.SelectionEventHandler):
    def __init__(self):
        super().__init__()
    def notify(self, args):
        eventArgs = adsk.core.SelectionEventArgs.cast(args)

        # Code to react to the event.
        ui.messageBox('In MySelectHandler event handler.')

 Is there any sample of event on select? with message box or something?

Can any1 help me please?

Thanks,
Jan

Hi @JanNavratil .

It is necessary to implement what is described in Help.

I made a simple Select Event sample.
I think you will need a code that is at least this long.

#Fusion360API Python script
#Author-kantoku
#Description-Select Event Sample

import adsk.core, adsk.fusion, traceback

_commandId = 'SelectionEvent'
_SelIpt1ID = 'Selectioninput1'

_handlers = []
_app = None
_ui = None

class CommandDestroyHandler(adsk.core.CommandEventHandler):
    def __init__(self):
        super().__init__()
    def notify(self, args):
        try:
            adsk.terminate()
        except:
            if _ui:
                _ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

class MySelectHandler(adsk.core.SelectionEventHandler):
    def __init__(self):
        super().__init__()
    def notify(self, args):
        eventArgs = adsk.core.SelectionEventArgs.cast(args)

        # Code to react to the event.
        _ui.messageBox('In MySelectHandler event handler.')

class CommandCreatedHandler(adsk.core.CommandCreatedEventHandler):
    def __init__(self):
        super().__init__()
    def notify(self, args):
        try:
            cmd :adsk.core.Command = args.command

            onDestroy = CommandDestroyHandler()
            cmd.destroy.add(onDestroy)
            _handlers.append(onDestroy)

            onSelect = MySelectHandler()
            cmd.select.add(onSelect)
            _handlers.append(onSelect)

            inputs = cmd.commandInputs
            i1 = inputs.addSelectionInput(_SelIpt1ID, _SelIpt1ID,  _SelIpt1ID)
            i1.setSelectionLimits(0)

        except:
            if _ui:
                _ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

def run(context):
    try:
        global _app, _ui
        _app = adsk.core.Application.get()
        _ui = _app.userInterface

        cmdDefs = _ui.commandDefinitions

        cmdDef = cmdDefs.itemById(_commandId)
        if cmdDef:
            cmdDef.deleteMe()

        cmdDef = cmdDefs.addButtonDefinition(_commandId, _commandId, _commandId)

        onCmdCreated = CommandCreatedHandler()
        cmdDef.commandCreated.add(onCmdCreated)
        _handlers.append(onCmdCreated)
        cmdDef.execute()

        adsk.autoTerminate(False)
    except:
        if _ui:
            _ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

Thank you for the sample. cool!

[JanNavratil]

Again, thank you !
Can I ask you, is there event for CAM strategy creation or toolpath in manufacturing part?

I was not able to find it in the documentation.

If you look at this Derived Classes, there seems to be no event related to CAM.

https://help.autodesk.com/view/fusion360/ENU/?guid=GUID-8fe1eb12-c1dd-4bb5-b8f5-18ec63a5f464 

If you use the Application.registerCustomEvent method, you may be able to do something, but it seems difficult.
