I've tried two different approaches. The first thing I tried was to make may app-delegate the delegate for my window and then implement -windowWillReturnFieldEditor:toObject:.
- (void)awakeFromNib
{
_fieldEditor = [NSTextView new];
[_fieldEditor setFieldEditor:YES];
NSDictionary* attributes = [NSDictionary dictionaryWithObjectsAndKeys:
[NSColor redColor], NSBackgroundColorAttributeName, /* something obvious so I can see it */
[NSColor yellowColor], NSForegroundColorAttributeName,
nil];
[_fieldEditor setSelectedTextAttributes:attributes];
}
- (id)windowWillReturnFieldEditor:(NSWindow *)sender toObject:(id)client
{
if ( [client isKindOfClass:[NSTextField class]] )
{
return _fieldEditor;
}
return nil;
}
Next, I tried something I found in a blog via Google at http://www.ff00aa.com/fr/archives/2009/02/28/9969-changing-the-selected-text-s-color-for-an-nstextfield/.
- (void)viewDidMoveToWindow:(NSWindow *)window
{
if ( window != nil )
{
NSDictionary* attributes = [NSDictionary dictionaryWithObjectsAndKeys:
[NSColor redColor], NSBackgroundColorAttributeName,
[NSColor yellowColor], NSForegroundColorAttributeName,
nil];
// object-shadow text-field
NSTextView *fieldEditor = (NSTextView *)[window fieldEditor:YES forObject:_shadowTextField];
[fieldEditor setSelectedTextAttributes:attributes];
// vignette text-field
fieldEditor = (NSTextView *)[window fieldEditor:YES forObject:_vignetteTextField];
[fieldEditor setSelectedTextAttributes:attributes];
// opacity text-field
fieldEditor = (NSTextView *)[window fieldEditor:YES forObject:_opacityTextField];
[fieldEditor setSelectedTextAttributes:attributes];
}
}
End result: In both cases I get the default white on cyan or whatever color you call it. Anyone have a technique that works or some experience with this type of modification?
