I'm subclassing NSTextFieldCell to display an icon (a favicon of a webpage,
to be specific) in the left end of the text field. The text field's cell is
set to my subclass in Interface Builder. When I start my application, the
icon is displayed, but the text that should be in the text field is not.
When the text field is in focus, it beeps every time you hit a key and
doesn't display the key you pressed. I've been trying to figure this out for
quite awhile to no avail. Here is the interface file:
@interface SBIconTextFieldCell : NSTextFieldCell {
NSImage *icon;
}
@property(nonatomic, retain) NSImage *icon;
@end
And this is the implementation file:
#import "SBIconTextFieldCell.h"
@implementation SBIconTextFieldCell
- (NSImage *)icon {
return icon;
}
- (void)setIcon:(NSImage *)newValue {
[icon release];
icon = [newValue retain];
[icon setFlipped:YES];
if (icon) [[self controlView] setNeedsDisplayInRect:NSMakeRect(2, 3, 16,
16)];
else [[self controlView] setNeedsDisplay:YES];
}
- (void)dealloc {
[icon release];
[super dealloc];
}
- (void)drawInteriorWithFrame:(NSRect)frame inView:(NSView *)controlView {
NSRect rect = NSMakeRect(2, 3, 16, 16);
if ([controlView needsToDrawRect:rect])
[icon drawInRect:rect fromRect:NSZeroRect operation:
NSCompositeSourceOver fraction:1];
if (icon) {
frame.origin.x += 16;
frame.size.width -= 16;
}
[super drawInteriorWithFrame:frame inView:controlView];
}
- (void)editWithFrame:(NSRect)rect inView:(NSView *)view
editor:(NSText*)text delegate:(
id)object
event:(NSEvent *)event {
if (icon) {
rect.origin.x += 16;
rect.size.width -= 16;
}
[super editWithFrame:rect inView:view editor:text delegate:object event
:event];
}
- (void)selectWithFrame:(NSRect)rect inView:(NSView *)view
editor:(NSText*)text delegate:(
id)object
start:(NSInteger)start length:(NSInteger)length {
if (icon) {
rect.origin.x += 16;
rect.size.width -= 16;
}
[super selectWithFrame:rect inView:view editor:text delegate:object
start:start length:length];
}
@end
Does anyone have insight as to what I'm doing wrong?
