问题 I'm working on a MacOS menu bar app which needs to track some global shortcuts in order to facilitate adjusting display brightness on external monitors. However, I cannot get it to fire a handler on any keyboard related events (mouse events work just fine). I'm checking Accessibility with the following code NSDictionary *options = @{CFBridgingRelease(kAXTrustedCheckOptionPrompt): @YES}; BOOL accessibilityEnabled = AXIsProcessTrustedWithOptions((CFDictionaryRef)options); Then, I'm adding a

问题 I have several NSViews that trigger re-draws during the mouseEntered and mouseExited methods. When showing an NSMenu in the same window, updating of those NSViews is suspended (they don't get the mouseEntered and Exited events). My problem is that once the NSMenu is closed (after moving the mouse all over the window outside of the NSMenu), every mouseEntered and Exited event that would have been triggered immediately trigger in a fast sequence. So basically they were queueing up and then

问题 When "tap to click" checked, how judge NSEvent is from trackpad click(pressed down) or tap to click. - (void)mouseEvent:(NSEvent*)theEvent { if ((type == NSLeftMouseUp || type == NSLeftMouseDown) && [theEvent subtype] == NSEventSubtypeTouch) { // How to detect touchpad is real pressed?? Not tap to cllick } } 回答1: To find out if someone only "tap to click" you could use func pressureChange(with event: NSEvent) in your NSViewController on NSView. If someone only "tap" the function will not be

问题 I have tried KeyDown and NSEvent , but they require a NSWindow object to be active. My hope is that I can put an app on the status bar and alert the user when it has pressed CapsLock , even if the user is in any other app. My app idea doesn't have a window for settings or anything else, is just an indicator. Can it even be done? I am guessing the AppDelegate but can't figure out how to make it receive modifier events. Any help really appreciated! I have looked on stack overflow for a

问题 I have a NSStatusItem and I want to popup a menu by rightclicking the item. I subclassed a NSView and overwrote the - (void)rightMouseDown:(NSEvent *)event method. I also implemented - (void)mouseDown:(NSEvent *)event for looking at the modifierflags. My problem is, that the view does not recieve the NSRightMouseDown -Event. And I don't know why? Any ideas how to get this event? Naturally I added the custom view to the statusitem. - UPDATE - Additional information: I have added a NSImageView

问题 I’m trying to replicate the behaviour of the search field in iTunes, for looking up stock symbols and names. Specifically, as you start typing in the search field a popover appears with the filtered items. For the most part I have this working however what I can’t replicate is the way it handles first responder I have my popover appear after three characters are entered. At this point the NSSearchField would lose first responder status and therefore I could no longer continue typing. The
