Scala.swing How does one scala components to current window size -

-

i'm trying display image in simpleswingapplication. make image change size when window changes size (i.e. manually dragging cursor adjust size).

i think done listening something, reacting uielementresized.

but i'm not sure how it.

i've tried:

        listento(top) \\ or window/frame/uievent         reactions += {             // case uielementresized=>             case class uielementresized(source: uielement); => // or without semicolon, without "source: uielement", without "class", , few other permutations.                println(size)          }

i asked similar question yesterday, narrow. want make more broad question entire problem.

i'm not familiar swing, looks reactions use partial functions callbacks. issue in pattern matching syntax, try

reactions += {     case uielementresized(source) => println(source.size) }

you can find more detailed examples here: listeners , reactions in scala swing

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
