About Mouse Click Event

[Anonymous]

I am thinking about some Revit API such that I can select a lamp, and using "double click" or "right click" with mouse to do something.

Is there some function can be used for the application above?

Thanks !

Dear Wyfeng,

The Revit API does not provide any specific support for this whatsoever.

Also, I am not sure whether it will help you users if you modify the behaviour of the standard Revit user interface. I would suggest always working with the system, not against it.

There is nothing to stop you from using the Windows and .NET API to determine the single and double clicks and doing what you like with them.

However, always be aware that you need to be inside a valid Revit API context to make calls to the Revit API.

If you use the Windows API to determine a mouse click, you will not be in a valid Revit API context; you will basically be in a modeless context and driving Revit from outside if you wish to access the API:

It is possible to determine what element is under the mouse cursor, once you have access to Revit API functionality:

Good luck playing with this!

Cheers,

Jeremy

Is there an actual namespace or class in the Revit UI API that handles basic Revit events like mouse click, orbit, zoom, pan, etc...?

I suggest you read the getting started material, since it also describes the available documentation and resources:

https://thebuildingcoder.typepad.com/blog/about-the-author.html#2

The Revit API documentation provides a list of all namespaces, classes, methods and properties:

https://www.revitapidocs.com

The functionality you request is partially handled by the Autodesk.Revit.UI.Selection namespace:

https://www.revitapidocs.com/2020/11785869-cc9e-03fc-97db-767a59af10a1.htm

As hinted at above, it does not provide much in the way of what you are asking for.

Probably, most of what you mean is not supported at all by the Revit API.

Hi Jeremy,

Thank you very much for your response. I took a look at the links that you sent and it seems the Revit API provides limited access to those basic events. Is there any other way to be able to edit them than through the Revit API?

[jeremytammik]

Thank you for your appreciation.

Yes, absolutely.

Please read the previous answers above.

Maybe there is something I’m missing here but it seems that all the links that you provided above refer only to the Revit API

[jeremytammik]

Ha, ha, ha.

Are you aware that this discussion forum s dedicated exclusively to the Revit API?
