NSImageView double click action

nsimageview, xcode

Solution

You need to subclass NSImageView and add the following method to your subclass's implementation:

- (void)mouseDown:(NSEvent *)theEvent
{
    NSInteger clickCount = [theEvent clickCount];

    if (clickCount > 1) {
        // User at least double clicked in image view
    }
}

Problem

I have some NSImageView in my Mac App where the user can drag'n drop objects like .png or .pdf, to store them into User Shared Defaults, that works fine. I would now like to set an action for when user double click on these NSImageView, but it seems to be a little bit difficult (I had no trouble for NSTableView, but 'setDoubleAction' is not available for NSImage, and tons of answers (here or with google) concerning NSImageView's actions point to making a NSButton instead of NSImageView, so that doesn't help) Here is part of my AppDelegate.h: ``` @interface AppDelegate : NSObject <NSApplicationDelegate>{ (...) @property (assign) IBOutlet NSImageView *iconeStatus; (...) @end ``` and here is part of my AppDelegate.m: ``` #import "AppDelegate.h" @implementation AppDelegate (...) @synthesize iconeStatus = _iconeStatus; (...) - (void)awakeFromNib { (...) [_iconeStatus setTarget:self]; [_iconeStatus setAction:@selector(doubleClick:)]; (...) } (...) - (void)doubleClick:(id)object { //make sound if that works ... [[NSSound soundNamed:@"Basso"] play]; } ``` But that doesn't work. Can anyone tell me what's the easiest way to do this ?
