06/03/2020, 9:39 PMand what this reall does is: - b

06/03/2020, 9:39 PMprivate function set_text(value) behaviours.set("text", value) - b
bright-gpu-74537
06/03/2020, 9:40 PMand then finally in the native backends (or any backend really) you can replace that behaviour (which defaults to TextBehaviour) with anything you want - b

06/03/2020, 9:40 PMso in the case of button: - b

06/03/2020, 9:41 PMonly behaviour and size are understood by haxeui-core, the handler is just for haxeui-hxwidgets - b

06/03/2020, 9:41 PMyeah, bit of a long explanation! 😄 - u
user
06/03/2020, 9:42 PMit gave me the time to write my first try - u
user
06/03/2020, 9:42 PMfailure - u
user
06/03/2020, 9:42 PMbut I wonder if it's because the @:build doesn"t work for a component... - b
bright-gpu-74537
06/03/2020, 9:43 PMcan you paste the code if its just test / small code - u
user
06/03/2020, 9:44 PMthe components aren't even visible on screen - u
user
06/03/2020, 9:44 PMso I assume I'm fighting with width/height again - b
bright-gpu-74537
06/03/2020, 9:44 PMcan you paste the custom component? - u
user
06/03/2020, 9:45 PM(i removed every width/height value to debug) - c

bright-gpu-74537
06/03/2020, 9:45 PMlooks fine to me, let me try it - u
user
06/03/2020, 9:46 PM@User you missed the guide about behaviors 😉 - c
clever-oil-61353
06/03/2020, 9:46 PMlol - u
user
06/03/2020, 9:46 PMit should be copy/pasted on https://github.com/haxeui/haxeui-guides - b
bright-gpu-74537
06/03/2020, 9:46 PMa rather long winded, fragmented guide 😄 - c
clever-oil-61353
06/03/2020, 9:46 PMi'll be scrolling for it later lol - u
user
06/03/2020, 9:46 PMok it works with no width/height - b
bright-gpu-74537
06/03/2020, 9:47 PMyeah, i should probably write a little guide about it, to be honest, for the most part you dont really need to touch behaviours unless you are introducing a new native component type - u
user
06/03/2020, 9:48 PMan all in one component with button is common - u
user
06/03/2020, 9:48 PM"composite component" sorry
