swift - Overriding a function outside its class -

-

i came across strange behaviour. following code produces compile error call bar() message: "missing argument parameter #1 call"

func bar() {     println("bar no argument") }  class classa {      func bar(varofanytype: string) {         println("bar argument")     }      func foo() {         bar()     } }

if change bar() function's name no errors:

func barnamechanged() {     println("bar no argument") }  class classa {      func bar(varofanytype: string) {         println("bar argument")     }      func foo() {         barnamechanged()     } }

what's reason compiler not allowing override function outside class?

cheers, daniel

at moment, swift compiler cannot distinguish between method , global function same name, regardless of overloading.

the solution prefix global function module name, e.g.,

func bar() { }  class classa {     func bar(anything: string) {}     func foo() { module.bar() } }

i have following code almost works properly; private void cbstatus_drawitem(object sender, listboxdrawitemeventargs e) { string item = e.item string; if (item != null) { switch (item) { case "1": e.appearance.forecolor = color.green; e.appearance.backcolor = color.green; break; case "2": e.appearance.forecolor = color.orange; e.appearance.backcolor = color.orange; break; case "3": e.appearance.forecolor = color.red; e.appearance.backcolor = color.red; break; } } } when dropdown shown, items forecolor correct, backcolor remains whatever backcolor of theme is; i.e. if i've got set dark theme, backcolor dark, cells in gridview, rather being green/orange/red. i've tried setting e.appearance.options.usebackcolor trying set e....
