cocoa - How to change color of divider in NSSplitView? -


can change color of divider? apple documentations says, can override -dividercolor in subclass of nssplitview this, doesn't works me, or understanding isn't correct. i've try create color layer on divider, e.g.:

colorlayer = [calayer layer]; nsrect dividerframe = nsmakerect([[self.subviews objectatindex:0] frame].size.width, [[self.subviews objectatindex:0] frame].origin.y, [self dividerthickness], self.frame.size.height);  [colorlayer setbackgroundcolor:[color coregraphicscolorwithalfa:1]]; [colorlayer setframe:nsrecttocgrect(dividerframe)];  [self.layer addsublayer:colorlayer];

not works.

i've tried subclassing - (void)dividercolor , i'm not sure why doesn't work though know it's being called (and it's in documentation).

one way change color of divider subclass - (void)drawdividerinrect:(nsrect)arect. however, reason, method isn't called , i've checked on web answers, couldn't find anything, ended calling drawrect. here code subclassed nssplitview:

-(void) drawrect {     id topview = [[self subviews] objectatindex:0];     nsrect topviewframerect = [topview frame];     [self drawdividerinrect:nsmakerect(topviewframerect.origin.x, topviewframerect.size.height, topviewframerect.size.width, [self dividerthickness] )]; }  -(void) drawdividerinrect:(nsrect)arect {     [[nscolor redcolor] set];     nsrectfill(arect); }
