Clojurians Log v2
cljfx
hi! I'm trying to render a tree-view with tree-items that change its value depending if they are expanded or not but couldn't figure out how. Is it possible with cljfx tree-view component?
I would say it's possible if you listen to :on-expanded-changed . Is it for some sort of a lazy-loading of data? I can try to make it an example...
Made an example: https://github.com/cljfx/cljfx/blob/master/examples/e38_lazy_loaded_tree_view.clj
oh, thanks for the example!
no it isn't for lazy loading
I'm using a tree-view to explore a clojure value (possibly nested collections)
and I'm trying to copy the UX of the javascript chrome console on JS objects
it changes the tree-item text depending on it being collapsed
it would be super handy if the tree-cell describe fn received a extra expanded? value in it's args
Not sure there are tree cells necessary? If you have expanded in the state, you can use it to control tree-item's text
Hi. I'm running into a strange bug where I am doing simple context changes, and the thread seems to hang without reaching the render stage. This happens only in some situations. Sorry that I do not have a clearer description, it is kind of a complex state machine 😕. Curious to hear if anybody knows about general bugs of this kind (i.e., changes that do not reach the render stage), and if there are typical gotchas related to that. 🙏
I'm not aware of such issues, could it be an infinite loop of subscriptions? Have you tried reproducing it with profiler running to see where the time is spent?
Haven't tried. Good idea, thanks! I'll also look into the subscriptions carefully.
(no JavaFX involved, just the context management system of cljfx)
