Cocoa: Right Click NSStatusItem

Question

I am a .Net developer who need to port a small project into Mac, so I know next to nothing about Objective C. In fact the code below was just a bunch of grasping at straws a

Answer 1

A more simplified response (Note, only works with control + click)

Properties:

@property (strong, nonatomic) NSStatusItem *statusItem;
@property (weak) IBOutlet NSMenu *statusMenu;

In Your Application Did Load:

[self.statusItem setAction:@selector(itemClicked:)];

Clicked Function:

- (void)itemClicked:(id)sender
{
    NSEvent *event = [NSApp currentEvent];

    if([event modifierFlags] & NSControlKeyMask) {
        NSLog(@"Right Click Pressed");
        [self.statusItem popUpStatusItemMenu:self.statusMenu];

    } else {
        // Do Nothing
        NSLog(@"Left Click Pressed");
    }
}

Answer 2

I would create a view and use the status items method.

-setView:

Then in the subclassed view you can detect ctrl+LMB using the following

- (void)mouseDown:(NSEvent *)theEvent
{
    [super mouseDown:theEvent];

    //Respond to the mouse click
    if ([theEvent modifierFlags] & NSCommandKeyMask) //Command + LMB
    {       
      //Do something
    }
}

I think you can figure out the rest.

Answer 3

If you will be satisfied with detecting control-click and not right click, then the first block of code will do what you want. If you really need the right click detection, you will have to use a custom view instead of an image in your NSStatusItem, and the second block of code will work.

Simple Method:

- (void)openWin:(id)sender {
    NSEvent *event = [NSApp currentEvent];
    if([event modifierFlags] & NSControlKeyMask) {
        [self openRightWindow:nil];
    } else {
        [self openLeftWindow:nil];
    }
}

Custom view method:

- (void)awakeFromNib {
    ...
    statusImage = ...
    MyView *view = [MyView new];
    view.image = statusImage;
    [statusItem setView:view];
    [statusItem setToolTip:@"Program Name"];
    view target = self;
    view action = @selector(openLeftWindow:);
    view rightAction = @selector(openRightWindow:);
    [view release];
    //[statusImage release]; //If you are not using it anymore, you should release it.
}

MyView.h

#import <Cocoa/Cocoa.h>
@interface MyView : NSControl {
    NSImage *image;
    id target;
    SEL action, rightAction;
}
@property (retain) NSImage *image;
@property (assign) id target;
@property (assign) SEL action, rightAction;
@end

MyView.m

#import "MyView.h"
@implementation MyView
@synthesize image, target, action, rightAction;
- (void)mouseUp:(NSEvent *)event {
    if([event modifierFlags] & NSControlKeyMask) {
        [NSApp sendAction:self.rightAction to:self.target from:self];
    } else {
        [NSApp sendAction:self.action to:self.target from:self];
    }
}
- (void)rightMouseUp:(NSEvent *)event {
    [NSApp sendAction:self.rightAction to:self.target from:self];
}
- (void)dealloc {
    self.image = nil;
    [super dealloc];
}
- (void)drawRect:(NSRect)rect {
    [self.image drawInRect:self.bounds fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1];
}
@end
