I have a Cocoa app in which one of my NSOpenGLViews can go into full screen mode (I do this with the method enterFullScreenMode:withOptions:). I would like to create a little widget that when you mouse over it, a toolbar pops up with some different controls. I am wondering what would be the best way to implement this widget? At first I thought about using a panel but I don't think you can bring up any windows when in full screen mode. Also, it seems that you can't add a subview to an NSOpenGLView? Are these two assumptions correct? What else could I use to accomplish this?
I would add a subview to the openglview's superview.
You can't add any subview to NSOpenGLView.
You can use glViewport to simulate subviews.

Simple question, starting out with macOS stuff – I’d like to create a small radial menu around my cursor, top-most, above whatever application is currently active, whenever a specific mouse button is pressed.
I have the specific mouse button over all application down, but I’m wondering where I need to draw that NSView, i.e. “topmost”. I guess on iOS this would be at the UIWindow level, but would NSWindow be the wrong approach here?
this is purely an opinion-based question, but basically if you want to present any custom content on the desktop, that should use NSWindow, and you can customise the window's content for your wish.
NOTE: you can find more information about the NSWindow class in Apple's Class Reference Docs.
I'm trying to add a "second row" after my NSToolbar in my app, that remains part of the title bar. As an example, Mail has a thin gray divider line below the NSToolbar with some extras items below that. Very specifically, when the window is put into fullscreen mode, that second "row" stays attached to the title bar as it slides down under the system menu bar. Xcode has a similar story.
I tried setting my NSWindow to textured and placing my second row controls directly in the content view of the window. While this mostly looks correct in windowed mode, those controls of course won't appear attached to the toolbar when it slides down in fullscreen mode. So how can I achieve the same behavior that Mail and Xcode do? I've looked at a lot of toolbar customization code but none of them really cover this specific case.
fullScreenAccessoryView is deprecated in macOS 10.10
In order to do this in recent versions of macOS, use the addTitlebarAccessoryViewController method on your NSWindow and pass in a subclass of NSTitlebarAccessoryViewController.
For example:
NSTitlebarAccessoryViewController *accessoryViewController = [[NSStoryboard storyboardWithName:#"Main" bundle:nil] instantiateControllerWithIdentifier:#"AccessoryViewController"];
[self.mainWindowController.window addTitlebarAccessoryViewController:accessoryViewController];
What I needed to do was call [NSToolbar setFullScreenAccessoryView:] on the view below my toolbar. This results in the behavior I was aiming for. See the NSToolbar documentation for this method.
First one is normal toolbar. For second toolbar you can create a separate view of your desired height and add it in the main landing-window.
Is there a bevel style that can replicate NSToolbar style of buttons that are used, for instance, in the Safari's preferences window to switch between different panes?
I need to replicate NSToolbar in an NSView using NSButtons. I understand that I should probably be using NSTabView, but I'd like to implement the look of xcode's left pane. Any tips here would be appreciated greatly.
There's nothing built-in, you'd have to create the images yourself. However, replicating the behaviour is straightforward.
You could simply use a single-row NSMatrix of NSButton objects. Just give the buttons an image and an alternate image (for the highlighted state) and set the matrix mode to NSRadioModeMatrix.
XCode 4 (but also iTunes and other Mac apps) provide side or bottom bars that can be shown or hidden with a smooth animation as the user presses a button.
How can I obtain a similar effect in my applications?
You can use NSSplitView to do that. You can have more than 2 subviews in a split view (left|center|right) and you can build a kind of hierarchy for the different bars (center consists of top and lower split views).
The show/hide effect is not built in, though. But you should be able to use the animator to do that. Most certainly you can also define animations for hiding a view.
You could also use the BWSplitView of http://brandonwalkin.com/bwtoolkit/ where the show/hide animation is already included.
You could also consider subclassing NSViewAnimation, which I believe Xcode uses in a number of places to achieve its fancy animation effects.
I want to open an overlay window (pop up window) when a user selects a cell in my NSTableView similar to selecting an event in iCal. Selecting the event in iCal shows a Window to edit the event, but does so by smoothly animating the window open and adding an arrow pointing to the even in the underlying calendar. Does anyone know what is being used here? Is this a bunch of hidden/custom APIs or is this available for public use?
The editor pane appears to be a custom borderless, transparent window with a custom view (the view defines the shape and therefore the shadow it casts). Learn more here. You might even use MAAttachedWindow.
Regarding animation, it's as simple as asking the window's animator to animate the frame and the alpha value (grouping them together). You'll probably want to set everything up directly in its "start position" first (ie, while the window is off-screen, set its alpha to zero, and its frame to some smaller version so it "zooms in" a la iCal), then put it on screen and start the grouped animation:
[NSAnimationContext beginGrouping];
[[window animator] setFrame:someNewSlightlyLargerFrame];
[[window animator] setAlphaValue:1.0];
[NSAnimationContext endGrouping];
Once the grouping is ended, the animation will begin (asynchronously) and your code execution will continue. Something to think about is getting everything "staged" first (including making sure the subviews of your window are already updated beforehand, so they don't change in the middle of your animation ... unless you want them to).
So the two separate techniques you need to understand are a custom window and basic Cocoa animation.
If you're using OSX 10.7 and above, NSPopover will do the job you're looking for.
Are you talking about selecting even from a list at the bottom of iCal app?
Not sure what exactly you are referring to but there is an api for animating transformations within a timespan.
Looking at other Apple's applications, Apple's developers utilize the same api available to anyone else (mostly I guess). There is lots of stuff that can be customized and Apple customizes whatever is required until it looks right from design point of view ...
