Connecting slider to separate graphics view in OS X Cocoa using Swift -

-
i have custom class containing slider , plotting code , these connected view in os x storyboard. unfortunately, slider in plotting area , can not place in different part of window since slider not recognized outside of plotting class. (this seemed easy in objective c using nibs). can suggest way of doing this? slider code is: @ibaction func freqvalue(sender: nsslidercell) { freq = float(sender.doublevalue) display() } the custom plotting class sinecurveview. thanks! can make outlet in appropriate view , set programmatically there? might not have full understanding of setup however, im on ios side.

html - Auto adjusting image -

i'm trying make simple webpage when open it, photo called "wallpaper.jpg" adjust based on window size there's no scroll bars. photo 1920 x 1080 if matters. currently have: <html> <body bgcolor = "#000000"> <style> img { height:100%; width:100%; } </style> <img src = "wallpaper.jpg"> </body> </html> but it's still leaving vertical scrollbar first things first: don't use bgcolor deprecated, you should reset margin on body because has margin:8px default (the value may change depending on browser), remove white space around. then using img going have vertical scrollbar if img height higher viewport height (if img hasn't parent width ) so solution using image background , using cover make full page responsive body { margin: 0; background: url("//placehold.it/1920x1080") fixed no-repeat center center / cover } `
