Hi all,
\nI’ve seen some people request how to do a modal color panel. Well, carbon has GetColor(..) which ultimately uses the same NSColorPanel. So, you can set it to begin a modal session before you call GetColor(..). Here’s a code snippet:<\/p>\n

#import <Carbon\/Carbon.h><\/font><\/p>\n

\u00c2\u00a0 \u00c2\u00a0 <\/span><\/font>if<\/font> (GetColor(point, <\/font>\u00e2\u20ac\u0153\\p\u00e2\u20ac\u009d<\/font>, &inColor, &outColor)) {<\/font><\/p>\n
