07/22/2021, 8:41 PMinteresting... maybe add a trace there for the event type (and maybe id) to see what it spits out - u
user
07/22/2021, 8:41 PMYeah I'm already trace-debugging :P - u
user
07/22/2021, 8:44 PMwindow is null - b
bright-gpu-74537
07/22/2021, 8:44 PMinteresting, so
is happening faster than expectedchild.window.scheduleForDestruction(); - b
bright-gpu-74537
07/22/2021, 8:45 PMactually, no, i dont think its that - b
bright-gpu-74537
07/22/2021, 8:47 PMdoes just a "if window != null" fix it? - b
bright-gpu-74537
07/22/2021, 8:47 PM(in unmap event) - b
bright-gpu-74537
07/22/2021, 8:47 PM... ... i wonder if that is leaving refs though - u
user
07/22/2021, 8:48 PMYeah I'm not sure skipping events unmaping will be good :x - b
bright-gpu-74537
07/22/2021, 8:48 PMno, but it could also be part of the destruction in remove - b
bright-gpu-74537
07/22/2021, 8:48 PMbut does it actually stop the segfualt? - b
bright-gpu-74537
07/22/2021, 8:49 PMif it does, cool, its a band aid for now - u
user
07/22/2021, 8:49 PMhandleRemoveComponentAt is called before child.unregisterEvents in removeComponentAt, setting window to null - b
bright-gpu-74537
07/22/2021, 8:49 PMyeah - u
user
07/22/2021, 8:49 PMin handleRemoveComponent, it's called later - u
user
07/22/2021, 8:50 PMin removeComponent * - b
bright-gpu-74537
07/22/2021, 8:52 PMwell, i think its an easy fix - i just need to test it out a bit as ive certainly removed components (and destroyed them) without any issues... so there is something "special" going on here - b

07/22/2021, 8:54 PMill sort it out tomorrow though... something is off... native UI's are such fun 😄 - u
user
07/22/2021, 8:55 PMTrying to fix it and getting segfaults at startup 😆 - u
user
07/22/2021, 8:56 PMOh, I did fix it °° - u
user
07/22/2021, 8:58 PM - u
user
07/22/2021, 8:59 PMI copied behavior from removeComponent() - u
user
07/22/2021, 8:59 PMMight make handleRemoveComponentAt() useless - b
bright-gpu-74537
07/22/2021, 9:01 PMnice one, ill check out the PR... but i also need to understand why for me its totally fine: - u
user
07/22/2021, 9:01 PMusing removeComponentAt? with wxwidgets? - b
bright-gpu-74537
07/22/2021, 9:01 PMCopy codexml <hbox id="container"> </hbox> <hbox> <button text="Add" onclick="container.addComponent(new haxe.ui.components.Button()).text='Button'" /> <button text="Remove" onclick="container.removeComponentAt(0)" /> </hbox> - u
user
07/22/2021, 9:01 PMHmm - u
user
07/22/2021, 9:01 PMMaybe because in my case the label is removing itself? - b
bright-gpu-74537
07/22/2021, 9:02 PMright, maybe
