Popup menu implementation from NSButton

Question

How should I go about it?

I was thinking about...

[NSMenu popUpContextMenu:menu withEvent:event forView:(NSButton *)sender];

Answer 1

Yup.

On button action call

[NSMenu popUpContextMenu:menu withEvent:event forView:(NSButton *)sender];

where

• menu : menu you want to show
• sender : button you clicked
• event : a new NSEvent you create

When you create the new NSEvent, specify the location as to where you want the popup menu to be shown.

Swift version of accepted answer

@IBAction func actionOccurred(sender: NSButton) {
    if let event = NSApplication.sharedApplication().currentEvent {
        NSMenu.popUpContextMenu(sender.menu!, withEvent: event, forView: sender)
    }
}

Updated answer

Add NSMenu to the NSViewController in the storyboard as seen in the image

Connect the Outlet

Right-click on the button in the storyboard and connect the menu outlet to the menu that we have just added to the storyboard(Where arrow points in the image)

Add IBAction

@IBAction func menuClicked(_ sender: NSButton) {
    var location = NSEvent.mouseLocation
    location.x -= 10; location.y -= 10 // Menu appears below the button
    let menu = sender.menu!
    menu.popUp(positioning: menu.item(at: 0), at: location, in: nil)
}
