I have an NSTableView (URLs of songs) and QTMovieView elements. I need to create an action that will execute when previous/next buttons on QTMovieView will be pressed. what I need to do?
If you want to do custom things, don't use the QTMovieView's control bar. You'll have to make your own controls with their own actions. Those actions will do what you need them to do as well as tell the movie view to play/pause, seek, etc.
You can turn the control bar off on a QTMovieView. Since you appear not to be using the video portion of the movie view, however, you could get rid of it entirely, using your own controls.

I am using a UIPageViewController to display certain content. I want to be able to display additional content when the user pulls down on the page using a UIPanGestureRecognizer. I can't seem to figure out what I should add my gesture recognizer to such that it does not cancel any of the pageviewcontroller's actions.
One of the apps I worked on has functionality similar to this. It shows a full-screen UIPageViewController, but if the user drags down on a ribbon on the top right corner, it will slide the whole thing down to reveal a view behind (for settings and other stuff).
I think your problem is that the built-in gesture recognizers are for the page turns. So what you'd want to do is either have something to drag on (such as the ribbon on the top left in my app) that will have its own gestures. OR you can iterate through the gesture recognizers that are assigned to UIPageViewController and get the one that matches the PanGesture, then override it with your own functionality to either delegate the event to the UIPageViewController or do the slide down, based on the type of pan.
Hope that helps.
My iPad (!!) app has a table view as the UISplitViewControllers details controller. To trigger various actions I use the following:
A swipe gesture on the cells to make a button visible that is called "Action".
Touching the action button shows a UIActionSheet with various options (Delete, Send, Download).
Touching one of the buttons in the action sheet triggers the action.
To achieve this behavior I customized the title of the "Delete" button which would normally be shown by the swipe gesture.
Please note that touching the cell itself will open/preview the touched item.
However, my test users complain that they cannot find the action menu because they would never try swiping the cells and if they would, they would do it to delete the entry. But they like that touching the cell previews the item.
Hence my question: what is the correct way of doing it? Show a disclosure button in every row (the little blue arrow to the right)? Show UIBarButtonItem in every row to bring up the action menu?
I'm so against it because it looks ridiculous to have a button in every row.
Sounds like a tricky situation; I'd either:
Add a detail disclosure button to each cell, and have that push a new view controller with the options (like the YouTube app).
Show the options in the "entry" view and have the "swipe" action an extra, discoverable feature (like the Twitter app).
I'm trying to implement some rudimentary tabs in a Cocoa editor I'm working on. I am using an NSSegmentedControl and adding segments to it as tabs. I'm using a custom NSSegmentedCell subclass for the tabs to draw a little 'x' icon next to the text for closing tabs and so far it's been going pretty smooth.
However, I cannot figure out how to actually process mouse events for the tabs to check if someone moused over (or clicked) the 'x' icon. I tried overriding "mouseMoved" in my NSSegmentedControl subclass, but for some odd reason it stops getting called when I add a new segment to it (I set "setAcceptsMouseMovedEvents" to yes in awakeFromNib, do I have to also set it somewhere else??). NSSegmentedCells, being NSCell subclasses seem to not have any mouse event processing, aside from mouse tracking, which gets triggered only when the control is clicked.
So the question is, how would I properly process mouse events, either in the NSSegmentedControl or in the NSSegmentedCell subclass?
Take a look at NSTrackingArea. You can add a tracking area to your NSSegmentedControl and get mouse-entered events on that to highlight the close button.
As for getting the click events, you're probably best off using a separate NSActionCell subclass for the close button and do some hit testing there.
How would make a Status Item when the actually button is clicked in the Menu Bar not in a drop down menu show or hide a window?
Sorry if this is a bit vague.
NSStatusItem supports the target/action mechanism like many other controls. I haven't used this myself -- I've only ever used an NSStatusItem with a menu attached -- so I don't know when the message is sent (i.e. when the mouse button is clicked or when it's released). If it doesn't do what you want by default, you would need a custom view like Daniel suggests.
To achieve this with NSStatusItem you need to create a custom view and replace the default NSStatusItem view by calling its "setView:" method.
You'll implement code in your custom view to react to mouse clicks by e.g. putting up a window. (You can use a button, or other standard views if it works best for you).
I'll warn you this is a bit tricky to get right. Lots of little nuances e.g. with getting the look of your custom view to look right in the menu bar. But this is the general approach you need to take if you want to override the default menu-prompting status item view.
I have an NSPopUpButton providing the NSMenu for a status item with a custom view. The popup button displays a list of links. When the user selects a link from the list, the link is displayed in the user's browser (in the background).
Naturally, the menu closes every time the user selects a link.
I would like to change this: I want the menu to stay open while the user clicks on various links, all of which can be opened in the background. The menu can then go away when the user clicks elsewhere.
How can this be accomplished? Should I subclass NSMenuItem and intercept the mouse clicks somehow? Overlay a transparent NSView on the popped-up menu and, again, intercept the clicks somehow? I make these suggestions blithely, but I would have trouble implementing either of these...pointers to the right methods for override would be appreciated.
Instead of using a menu, one might use a collapsible box.I have seen that in many apps ( also provided by Apple) , so I guess this is the recommended style guide for multiple selections.
The collapsible box expands when you click the disclosure button, and it gives free all items desired - like a tableview with checkboxes.
Views below this box must move down in this case, not to interfere with the box.
Clicking again on the disclosure button will shrink the box back to its origin. The effect is similar to closing a menu.
Usually you should not bend a control too far past it's original intent. Users expect pop up buttons to close after making a selection. I don't think you should, or can, force NSPopUpButtonCell to behave in this way. If you do, you'll be subclassing and modifying the control so heavily that it might change/break with a future version of Mac OS X. You'd also have to worry about the usability problem of users thinking the menu will close after making a selection.
You might consider writing you're own subclass of NSView to work like the menu button you're describing. After the user clicks on the button. You'll want to create a new NSWindow, with no border by using NSBorderlessWindowMask as the style mask. The content view of that window should be another custom view of yours that you implement the menu selection in.
