swift - Textured NSWindow Background Gradient -


i trying generate own textured nswindow appears different gradient default metallic appearing one.

so far i've subclassed nswindow no success below.

import cocoa  class pswindow: nswindow {      override init(contentrect: nsrect, stylemask astyle: int, backing bufferingtype: nsbackingstoretype, defer flag: bool) {         super.init(contentrect: contentrect, stylemask: astyle, backing: bufferingtype, defer: flag)          let gradient: nsgradient = nsgradient(startingcolor: nscolor(red: 48 / 255, green: 35 / 255, blue: 174 / 255, alpha: 1), endingcolor: nscolor(red: 200 / 255, green: 109 / 255, blue: 215 / 255, alpha: 1))          gradient.drawinrect(contentrect, angle: 45)     } }

am going correct way?

nswindow subclass of nsresponder , shouldn't drawing within it.

solutions:

  1. you should override "contentview" variable (custom window subclass) , set layer cagradientlayer create in set method of "contentview"

  2. create custom subclass of nsview , set view of custom window in storyboard/xib. in view either override drawinrect or use layer approach.

additionally here how draw custom nswindow

quick dirty code follows

import cocoa  class customwindow : nswindow {   override init(contentrect: nsrect, stylemask astyle: int, backing bufferingtype: nsbackingstoretype, defer flag: bool) {     super.init(contentrect: contentrect, stylemask: astyle, backing: bufferingtype, defer: flag)   }    override var contentview: anyobject {     set {       var view = newvalue as! nsview       view.wantslayer = true       let colortop = nscolor(red: 48 / 255, green: 35 / 255, blue: 174 / 255, alpha: 1).cgcolor       let colorbottom = nscolor(red: 200 / 255, green: 109 / 255, blue: 215 / 255, alpha: 1).cgcolor       let gradient  = cagradientlayer()       gradient.colors = [ colortop, colorbottom]       gradient.locations = [ 0.0, 1.0]       view.layer = gradient       super.contentview = view      }     {       return super.contentview     }   }    required init?(coder: nscoder) {       fatalerror("init(coder:) has not been implemented")   }  }

window background

solution 2:

import cocoa  class customview : nsview {    override func drawrect(dirtyrect: nsrect) {     let colortop = nscolor(red: 48 / 255, green: 35 / 255, blue: 174 / 255, alpha: 1)     let colorbottom = nscolor(red: 200 / 255, green: 109 / 255, blue: 215 / 255, alpha: 1)     let gradient = nsgradient(colors: [colortop, colorbottom])     gradient.drawinrect(dirtyrect, angle: 45)   } }

solution2

if need custom titlebar here. it's lot of work.

ps: remember actual drawing done in nsview
