Re: Can NSView and NSImageView respond to Mouse Clicks?

Jack Brindle
 

NSView inherits from NSResponder. That gives NSView access to mouseDown, mouseUp and a whole host of other important calls.
What this really means is that you can implement
- (void)mouseDown:(NSEvent *)event;
or
v- (void) mouseUp:(NSEvent *)event;
in your NSView subclass and handle mouse events the way you like, which includes generating IBAction calls to other objects that need to be notified of mouse events in your view.
The event object will contains information about where the cursor was when the mouse down or up even occurred, which you can use to determine exactly where in the view the hit occurred, and even when.
Note that any control embedded in the view will take precedence over the view itself, so that it gets a chance to handle the mouse down first.

After all these years, I still find it really cool the way events and the responder chain works, and gives us so much power to create great user interfaces.

Suggestion: open NSView.h and search for "menu", there are API like menuForEvent: and willOpenMenu: that look useful for your case.

Did you change your linked library to the new C++ one?

Using one of those (c++11), brings me back to the first warning. And then the compiler can't find the standard library headers (e.g. <algorithm>), anyway.

One of the suggested changes was "Update C++ Standard Library", so I reverted to pre-changes and didn't make that change, which got me to the second set of warnings.

Anyone have an idea how to break out of this cycle?

UILabel has `adjustsFontSizeToFitWidth` and `minimumScaleFactor` properties that aim to support that type of thing automatically. Could you employ it?

I build a lot of C++ and I don’t think I’ve ever seen that. Are you overriding the header search path or specifying any exotic compiler flags already? And double-check that you’ve got a valid SDK selected.

‘-std=libc++’ seems fishy to me, since the value of -std is supposed to be a language version like “c++11”.

Re: Segue

Rick Aurbach
 

I'm not sure I am understanding your problem correctly, but I am wondering about the exact layout of your storyboard. Specifically, are you using a UISplitViewController? The Push (Detail) segue is specific to it. 

On an iPhone (particularly in portrait mode), the push-detail segue looks like a simple push, but it is not. You can see this when running on an iPad in Simulator, where you will see both the TableViewController and the Detail controller (in whole or with part of it covered by the TableViewController) side by side. The push detail segue brings the detail controller to the front, covering (hiding) the TableViewController. On a phone, this just looks like a push.

If you don't have a split-view controller, then the segue can't do that (i.e., it can't call UISplitViewController.showDetailViewController) and is apparently doing a simple UIViewController.present instead.

If I'm off on a mistaken tangent here, please excuse the waste of bandwidth.

Adding Action Methods to Controls

Dave
 

Ignore this, was a silly bug in that the identifier wasn’t setup correctly!


Adding Action Methods to Controls

Dave
 

Hi,

I’ve created an NSButton Class and added an Action to it as so:

myButton = [[NSButton alloc] initWithFrame:myButtonFrameRect];
myButton.image = myImage;
myButton.imageScaling = NSImageScaleProportionallyUpOrDown;
self.pCellButton = myButton;

self.pCellButton.target = self;
[self.pCellButton sendActionOn:NSEventMaskLeftMouseDown];
[self.pCellButton setAction:@selector(performCellSelected:)];

[self addSubview:self.pCellButton];



-(void) performCellSelected:(id) theSender
{
NSLog(@"performCellSelected: theSender: %@", theSender.identifier);
}

This works ok, EXCEPT the parameter pass in “theSender” is nil???? I would have thought it should be the NSButton object that the Action was sent from is this not the case?

From the docs:

<https://developer.apple.com/documentation/appkit/nsimageview?language=objc>
Note
An image view calls its action method only when the user drags an image into the image view's bounds, and the image view must be editable to receive dragged images. If you want to display an image and respond to clicks in the image, use an NSButton object instead.
