Roassal observing click on any and all elements
 
|
Hi Alex,
I'm trying to find a way how to observe all mouse clicks regardless of elements. I can do this easily on my side, because I have control over everything I create, but doing that would prevent certain things like RTResizable from working in pure Roassal... Currently all Trachel mouse events are created in Morphic (TRMorph), however events themselves are fired from shapes' announcers so there is no convergence point. So, would it be possible to basically fire the event twice, once from the shape's announcer and once from probably view or canvas (or some TROverseer class or whatever). As far as performance goes this shouldn't be a problem if you consider that just mouse movement can trigger 10 events every second. What do you think? Is it worth for you to change/implement it? If not I will resolve it on my side. Thanks, Peter _______________________________________________ Moose-dev mailing list [hidden email] https://www.iam.unibe.ch/mailman/listinfo/moose-dev |

Hi!
Having this overseer will indeed address some problems. For example, clicking on a background to remove all the resize handle. I have just implemented something: c := TRCanvas new. s := TRBoxShape new size: 50. c addShape: s. click := 0. s when: TRMouseClick do: [ :evt | click := click + 1 ]. eo := TREventOverseer new. events := OrderedCollection new. eo block: [ :anEvent | events add: anEvent ]. c eventOverseer: eo. c I think you will need more. Probably that you do not want to capture all the event right? In particular, MouseMove is probably not interesting for you. Feel free to extend TREventOverseer as you wish.

Perfect! I've subclassed TREventOverseer to be able to use Announcer instead of block: []. But it works just as I wanted. :) Since I now use announcer I can easily do overseer when: TRMouseLeftClick do: [ :event | ] .... and thus I do not need to filter MouseMove at all. Thanks again!
