[ https://issues.jboss.org/browse/DROOLS-3406?page=com.atlassian.jira.plugi... ] Roger Martínez commented on DROOLS-3406: ---------------------------------------- Hey [~manstis] Well probably I'm still not familiar with this things you're doing and the issues behind, as we never did something like this before on to of Stunner shapes... So good to see you are feeling brave hehe :) I'll help as much as possible. Soo some comments: * TBH I don't understand how the actual resize stuff works for a Line, I mean by using _view.addHandler(ViewEventType.RESIZE, new ResizeHandler()...)_ . Are really the resize CPs appearing? on top of the line? and what's being resized? Can you please attach some screenshot or video?? it would help to have an idea... * About (a) - Add a CP to the line and fire some commands ** I see two parts here - the lienzo and stunner sides ** On lienzo size it's necessary to implement this new CP and its behavior in some way - maybe implementing the IControlHandle interface as others? not really sure if makes sense, but once given the ability, for your shape, to show/hide the CP, it should also provide some callback to let stunner know the CP has been "updated". As usually you can do this in different ways... options could be using an interface (like we do with the IContainmentAcceptor etc) or using the event bus by creating your own eventhandlers. ** On Stunner side I would implement a new "CavnasControl" and register it to your DMNSession. ** This way, once the control is enabled, it checks the elements being [registered|https://github.com/kiegroup/kie-wb-common/blob/master/kie-wb-c...] on the diagram/canvas. When the element being added is a DecisionService, you can obtain the Shape and ShapeView instances and register the new CP handler for the shape view instance. Once the lienzo handler do the callback call, on this new canvas control class you can then execute the commands in order to move the shape up / down ** once the control is disabled, you can remove any listener or whatever state added to the shape view instance. * About (b) - Resizing the DecisionService ** Well probably there is some (maksed) bug on the resize stuff on the core as well.. :/ sorry, let's to see if we can fix/improve this :) ** The idea is that the size value is always given by the "bean". So let's consider your DecisionService needs a width and height values - you should create both stunner properties for width and height as usually (annotations, forms, etc) and also specify the _PropertyMetaType.WIDTH/HEIGHT_ via annotations. ** The ShapeView implementation must implement or either _HasSize_/_HasRadiius_, or use a custom _ShapeViewHandler_ in order to update the right attributes given some size ** Once the bean has both properties and they're available from Stunner domain handlers (_PropertyMetaType.WIDTH/HEIGHT_): *** When updating the value from the properties panel (or any other component), it updates the values on the bean side, so it will update the width and height properties for the DecisionService bean. At thsi point, once a property has been updated, it should also refresh the shape on the canvas, so it uses the new size from the bean values. *** When resizing from the canvas, it actually uses a canvas control - the _ResizeControl_. The idea is the same as commented on above point (a) - register some handlers on the lienzo size when the element/shape is being added into the canvas, and listen for the callbacks in order to execute the right stunner commands *** This way the idea is that both properties panel or resizing from the canvas will update the bean values, and the (related) shape/s will be "refreshed" in order to use the new "size" given from the (updated) bean Well TBH not sure if I answered what you was expecting .... but at least could help a bit. Anyway please ping me or reach me out if you think we should do some call for this, np for me!! I'm now always starting so late hehe :).....seriously, np, just lemme know if you need me, I'll be on PTO for a couple of weeks this xmas so let's try to have this clear during this week, if you think so Thanks!! -- This message was sent by Atlassian Jira (v7.12.1#712002)
