Tweak events
Locked

Hi,
There is probably a very obvious answer to this question... How does my Tweak object tell Croquet which events it wants to handle? For Croquet Objects such as TFrame I can set the eventMask. I believe the same is true for Morphic objects. With Tweak I have played around with methods such as handlesEvent: on both the costume and the object and even though I set them to return false for things such as mousedown, the mouse down event never gets passed on. I would like to have a Tweak object which I can click through and do things in the Croquet Space. If my Tweak object contains anything that ever could handle mouse down (such as scroll pane in my case) even though I override the handlesEvent: I cannot pass that mouse click on to Croquet. What am I doing wrong? Thanks in advance for any help, Liz Wendland |

You probably want one of these three methods: onClick <on: mouseClick> "Your code here" onMouseDown <on: mouseDown> "Your code here" onFire <on: fire> "Your code here" See these two pages: http://tweakproject.org/TECHNOLOGY/Tutorials/BankAccountTutorial/ http://tweakproject.org/TECHNOLOGY/Documentation/PlayerEvents/ -- Matthew Fulmer -- http://mtfulmer.wordpress.com/ |

Hi Matthew,
Thank your for your reply. I have used the Tweak event handling quite a bit and it is very nice. My current problem is that I DO NOT want to handle these events and I want Tweak to pass them on to the Croquet environment. I believe there is a way to indicate that certain events should be ignored, but I'm not sure how to do that from Tweak. Thanks!

The only suggestion I have is to try tracing Tweak event handling, and to look at CroquetHarnessWithMenu and friends -- Matthew Fulmer -- http://mtfulmer.wordpress.com/ |

Liz,
I think you will still need to handle the event in tweak but you handle it by passing the event to the T object that needs to handle the event. You can try holding a reference to the T object that you want to use to handle the event and pass the event from the Tweak object to the T object. I do a lot of this in freeCAD/Croquet but I'm not sure if what you want to achieve is the same. You can try looking at some of the window GUI though.

Hi,
Thanks for the recommendations. John Dougan helped me find a way to do this... if you call: myPlayer locked: true for players you want to ignore events, the player will not be sent the events and they will pass on to the next layer. Exactly what I was looking for. I think what you are describing below, Fong, would work as long as I know which object I want to pass the event to. In my case I don't.

Hi Liz -
Locking the player is definitely one way to do it but it doesn't give you much flexibility and won't allow you to add any interactive object to that player. It works great if you (for example) want to use a translucent overlay (for annotations etc) that really is ignoring all the mouse events but it has limits. I would not recommend doing this for the "main view", i.e, the main display region of your application. In that case, I would strongly recommend to hold a reference to the T-object (some kind of harness I suppose?) and have the event handler forward the event explicitly.
