Is it possible for a menubar application icon to receive text by hovering it over the icon? I need to know how many characters are in the content before it is dropped on the icon. and if there is too many characters in the content i want the green circle on the cursor to turn red. Is this possible? What methods would i use to accomplish this? I could not find anything helpful on the documentation page.
The NSDraggingInfo is provided for -draggingEntered:, so you would have access to the draggingPasteboard containing the object even before the drop occurs.
As to changing the cursor, you would need to provide your own. Have a look at the NSCursor documentation.

I am a rookie Cocoa guy. I need to design and implement a view which will show collection of labels on Mac OS using Xamarin. These labels will have a text and color associated with them. When shown inside the view, label should expand till it covers whole text and it will be shown with background and foreground colors.
I have attached the picture of this user control on Windows, you can see that labels inside the StackPanel are expanding till they cover the whole text. Hope this gives better idea about my ask.
The $64,000 question is "are these labels controls?" In other words, do you expect the user to click on these to do something, or are they just for display?
If your answer is "just for display", the solution is super simple: Use an NSTextField and programmatically add attributed text (NSAttributedString) to it. Attributed text attaches display properties to runs of text within the field; properties like "background color".
If you want these to be buttons that you can click on, then things get a lot more complicated.
Since you apparently want the button layout to "flow", you might look into imbedding buttons (well, button cells) into an NSTextField using attachments. This is normally how non-text content (say, an image) can be inserted, but with some fiddling it can actually be anything a control cell can draw. See How to insert a NSButton into a NSTextView? (inline).
Warning: this is not a "rookie" topic and will involve control cells and custom event handling.
If I were doing this, I'd probably just create NSButton objects for each label (choosing an appropriate style/look like NSRecessedBezelStyle), create a custom subclass of NSView to contain them, and then override the layout method to position all of the buttons the way I want.
To be thorough, I'd also override the intrinsic size methods so the whole thing could participate in auto-layout, based on the number and size of buttons it contained.
So I am trying to emulate the new cleanlymac app. It looks like it has two windows on top of each other, one without the traffic lights and the other with it, but they were treated as one. That had the ability for the back one to slip out at the beginning. Would anyone have a good idea of how this was constructed?
Here is a photo of the cleanmymac app:
They are actually ONE WINDOW.
You can easily acheive this by using vertical NSSplitView with 2 panes.
Here you can opt for divider in between or fix the splitter.
And in each of the splitViews a new NSView is placed. Here in this view you can put your views from a single or multiple xibs.
Check here for ViewOnWindow how you can show a view from another xib to your main window.
Check here for tutorial.
That looks like a custom window with the black background for the top right part of the window. Search for custom window cocoa to find examples of how to do this. I don't see the point of the custom window in this situation, you could just split the content of the window, it probable branding.
I was wondering if any one knew how to save an load fonts on a textview. The app lets the user select the font for the text view but when they switch views and come back it is gone. Does any one know how to save that and then load it. Thanks so much.
Also if any one know how to save text color that would due great also.
Thanks so much!!
What you have to do is to give all the textViews a specific tag values and on navigation before view willDisappear you have to store all the values to array and on navigating back to the view on viewWillAppear fill all the textViews using the tag values.
When editing code, Xcode is capabale of displaying in-text controls, like drop down buttons which can show context menu's. I've seen other OS X apps that handle text capable of similar features. See the attached sample.
I presume this effect is obtained using NSTextAttachmentCell - although I'm not sure whether this is the proper way to implement this.
For my own app I would like to use this technique as well.
I have the following questions:
Is NSTextAttachmentCell the correct way to implement such a feature? If not, what would be?
How do I attach a control -comparable to the one in the above sample- to a specific range of text so that its location within NSTextView is dynamic and follows layout actions?
I found this which gives some hints but does not cover the attachment to specific text ranges.
Although NSTextAttachmentCell will work, it has a disadvantage: the cell will become just a glyph in the text which was not what I wanted. It distorts the layout of the text, is selectable etc. I wanted the cell to be drawn over the text, just like the behaviour in Xcode.
The challenge was to find a way of translating a point from a Mouse Moved event to the position of a particular string of characters inside the NSTextView.
After some more digging I found a little gem in Apple's demo apps called LayoutManagerDemo. This demo shows a custom subclass of NSTextView capable of highlighting individual characters, words and lines while the mouse is hoovering its view. From there on it was pretty easy to fade in a button at the required NSPoint and then show a popup menu with some options.
I am in the process of creating a small image editor.
What I aim, is to create a window with transparent titlebar, but not what contains inside the window.
I have check HUD Window, but it's really is a panel, not a window. And I am missing the regular close,maximize and minimize button.
Is there anyway to create such window?
Or can we modify HUD to hold regular close,max and min button?
Thanks so much in advance!

Use a standard borderless window approach and provide a content view that draws something. Even if the content view's bounds rect is just filled with [NSColor whiteColor].
Update: Re-reading, I see you seem to be asking for just a transparent title bare but still with the window controls. See this StackOverflow question for an approach at customizing a window's title bar. Careful, though - I'm not sure this would be accepted into the App Store. Best to have a backup plan in case it's not.
Here is what I found that match to what I want : window trasparency
The trick is making the main window transparent, but not the content by creating a special view for this.
