Here is the thing:
I have created a custom NSMenuItem with a custom NSView in it.
Everything works fine except that I can't get the NSMenuItem to get highlighted (= change the background color on mouseover).
I'm trying to do it inside the drawRect method, as shown in other answers posted here.
What am I doing wrong?
The NSView subclass:
@interface customView : NSView
@end
@implementation customView
- (id)initWithFrame:(NSRect)frame
{
NSRect theRect = NSMakeRect(0, 0, 200, 30);
self = [super initWithFrame:theRect];
if (self) {
NSTrackingArea * trackingArea = [[NSTrackingArea alloc] initWithRect:theRect
options: (NSTrackingMouseEnteredAndExited | NSTrackingActiveInKeyWindow |NSTrackingActiveAlways)
owner:self userInfo:nil];
[self addTrackingArea:trackingArea];
}
return self;
}
#define menuItem ([self enclosingMenuItem])
- (void) drawRect: (NSRect) rect {
BOOL isHighlighted = [menuItem isHighlighted];
if (isHighlighted) {
//this nslog never happens
NSLog(@"it's highlighted");
}
- (void)mouseUp:(NSEvent*) event {
NSMenuItem* mitem = [self enclosingMenuItem];
NSMenu* m = [mitem menu];
[m cancelTracking];
NSLog(@"you clicked the %ld item",[m indexOfItem: mitem]);
}
@end
The NSMenuItem subclass:
(I add subviews on the custom view here so i can have access to the controls through the NSMenuItem instance)
@interface customItem : NSMenuItem{
}
-(void)setTheText:(NSString*)theString;
@property NSTextField *theLabel;
@end
#import "customItem.h"
#import "customView.h"
@implementation customItem
@synthesize theLabel;
-(id)init{
if (self){
customView *cv = [[customView alloc] init];
theLabel = [[NSTextField alloc] initWithFrame:NSMakeRect(10, 8, 130, 17)];
[theLabel setEditable:NO];
[theLabel setBordered:NO];
NSButton *myButton = [[NSButton alloc] initWithFrame:NSMakeRect(170, 7, 20, 20)];
NSButton *myButton1 = [[NSButton alloc] initWithFrame:NSMakeRect(150, 7, 20, 20)];
[myButton setBezelStyle:NSCircularBezelStyle];
[myButton1 setBezelStyle:NSCircularBezelStyle];
[myButton setTitle:@""];
[myButton1 setTitle:@""];
[cv addSubview:myButton];
[cv addSubview:myButton1];
[cv addSubview:theLabel];
[self setView:cv];
[theLabel setStringValue:@"A Value "];
}
return self;
}
-(void)setTheText:(NSString *)theString{
[theLabel setStringValue:theString];
}
@end
And this is the App Delegate :
@interface AppDelegate : NSObject <NSApplicationDelegate>{
NSStatusItem *statusItem;
IBOutlet NSMenu *theMenu;
}
@property (assign) IBOutlet NSWindow *window;
@end
#import "customItem.h"
@implementation AppDelegate
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
}
- (void)awakeFromNib{
statusItem = [[NSStatusBar systemStatusBar]
statusItemWithLength:NSSquareStatusItemLength];
NSBundle *bundle = [NSBundle mainBundle];
NSImage *statusImage = [[NSImage alloc] initWithContentsOfFile:[bundle pathForResource:@"barIcon" ofType:@"png"]];
NSImage *highlightImage = [[NSImage alloc] initWithContentsOfFile:[bundle pathForResource:@"barIcon_H" ofType:@"png"]];
[statusItem setImage:statusImage];
[statusItem setAlternateImage:highlightImage];
[statusItem setMenu:theMenu];
[theMenu removeAllItems];
customItem *mi = [[customItem alloc] init];
[theMenu addItem:mi];
customItem *mi2 = [[customItem alloc] init];
[theMenu addItem:mi2];
}
@end
This is what i get:
