Hi all,

I am using below code to subclass NSTextField-

- (void)drawRect:(NSRect)dirtyRect
{
// black outline
NSRect blackOutlineFrame = NSMakeRect(0.0, 0.0, [self bounds].size.width, [self bounds].size.height-1.0);

NSGradient *gradient = nil;
if ([NSApp isActive]) {
gradient = [[NSGradient alloc] initWithStartingColor:[NSColor colorWithCalibratedWhite:0.24 alpha:1.0] endingColor:[NSColor colorWithCalibratedWhite:0.374 alpha:1.0]];
}
else {
gradient = [[NSGradient alloc] initWithStartingColor:[NSColor colorWithCalibratedWhite:0.55 alpha:1.0] endingColor:[NSColor colorWithCalibratedWhite:0.558 alpha:1.0]];
}
[gradient drawInBezierPath:[NSBezierPath bezierPathWithRoundedRect:blackOutlineFrame xRadius:7.6 yRadius:7.6] angle:90];



// top inner shadow
NSRect shadowFrame = NSMakeRect(1, 1, [self bounds].size.width-2.0, 10.0);
[[NSColor colorWithCalibratedWhite:0.88 alpha:1.0] set];
[[NSBezierPath bezierPathWithRoundedRect:shadowFrame xRadius:6.9 yRadius:6.9] fill];

// draw the keyboard focus ring if we're the first responder and the application is active
if (([[self window] firstResponder] == [self currentEditor]) && [NSApp isActive])
{
[NSGraphicsContext saveGraphicsState];
NSSetFocusRingStyle(NSFocusRingOnly);
[[NSBezierPath bezierPathWithRoundedRect:blackOutlineFrame xRadius:8.6 yRadius:8.6] fill];
[NSGraphicsContext restoreGraphicsState];
}

// main white area

NSRect whiteFrame = NSMakeRect(1, 2, [self bounds].size.width-3.0, [self bounds].size.height-7.0);
[[NSColor whiteColor] set];
[[NSBezierPath bezierPathWithRoundedRect:whiteFrame xRadius:8.6 yRadius:8.6] fill];

NSFont *stringFont = [NSFont fontWithName:@"Lucida Grande" size:18.0];

if ([[self stringValue] length] == 0) {
NSColor *txtColor = [NSColor grayColor];
NSDictionary *placeHolderDict = [NSDictionary
dictionaryWithObjectsAndKeys:txtColor, NSForegroundColorAttributeName,stringFont,NSFontAttributeName,
nil];

placeHolderString = [[NSAttributedString alloc]
initWithString:[[self cell] placeholderString] attributes:placeHolderDict];
[placeHolderString drawAtPoint:NSMakePoint(10.0,0.0)];
}
else {
NSColor *txtColor = [NSColor blackColor];
NSDictionary *txtDict = [NSDictionary
dictionaryWithObjectsAndKeys:txtColor, NSForegroundColorAttributeName,stringFont,NSFontAttributeName,
nil];

placeHolderString = [[NSAttributedString alloc]
initWithString:[self stringValue] attributes:txtDict];
[placeHolderString drawAtPoint:NSMakePoint(6.0,4.0)];
}

}

But I am facing two problems:

First Problem: When a text field is selected, it is showing overlapping white edges over round corners as shown in below image:

Second Problem: When cursor is in textField1 and I am pressing tab key, it is not moving to textField2 though in IB I have binded next key view of textField1 as textField2.

Can any one suggest me some solution for above problems?

Thanks
