    i wonder if i can maybe make hxcpp fail with a nice error message if some env var doesnt exist
  • b
    ¯\_(ツ)_/¯
  • b
    in fact, i can do that in the EntryMacro... ill make a note to do so
  • h
    there's another error
  • h
    aaaaaaaaaaaa whyyyyyyyyyyy
  • h
    it printed a bunch of stuff about unresolved external symbols for like a solid minute then did this
  • b
    they are linker errors, which means the the app has at least compiled
  • b
    its hard to be able to fix your problems without sitting at your machine, but your about 50% there
  • b
    my advice would be to download wxWidgets as source, and build it manually (via msvc), but on windows, that can be a real pain in itself
  • b
    maybe try and define (or undefine) 
    WXSTATIC
  • h
    that's what i was trying to do but i don't think i did it right
  • h
    OH
  • h
    it's pulling from a folder that doesn't exist
  • h
    i had it building in 64 bit mode but i didn't build wxwidgets for 64 bit
  • h
    oooops
  • h
    nope that wasn't the problem
  • h
    wait no that was the problem there’s just more problems
  • h
    at least i think i can fix it this time
  • r
    Ah that's the obvious answer I figured there must be, thanks!
  • r
    managed to do this to the Playground, trying to put hscript in a grid's onresize handler to set the columns based on its width
  • r
    Think it was likely due to a divide by zero
  • m
    I think this is an ultra dumb question, but how do I make a vertical slider start at the top?
  • m
    actually, wait, I might not need that
  • m
    Is there a way to change a component's value by code without triggering it's onChange event?
  • b
    not by default no, i mean, i guess you could remove the event listener, set the value and add the listener again - though i would guess if you are doing that there is something else wrong in your code?
  • b
    hmmm, any chance of a repro? Also, you can use % widths in headers etc, fyi
  • m
    If I remove the listener right after, it's too soon. The events trigger afterwards
  • b
    i mean, you could go:
  • b
    Copy code
    haxe
mySomething.removeListener(UIEvent.CHANGE, ...);
mySomething.value = 100;
mySomething.addListener(UIEvent.CHANGE, ...);
  • b
    but i would say, if you are doing that, something is "off"... i mean, why would you sometimes want the controls change event to do something and other times not
