I want to make a type of popupbutton sort of like the action button on OSX. I need to make the button have two images makeup the representation of the button (the icon for the button and the downward facing disclosure triangle next to it). I was thinking maybe I could add the second image as a subview of the button but it seems that there should be a simpler way to do this. Any ideas?
Make an NSPopUpButton whose pullsDown is set to YES (Type of “Pull Down” in IB) and whose image is set to the image named NSImageNameActionTemplate (“NSActionTemplate” in IB).

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.
How can I do something like that?
I didn't find any appropriate object in the Interface Builder library.
Any thoughts?
The best way that i found is to use NSSegmentedControl.
after you dragged it on the canvas, you should configure its style:
Style: Small Square
Mode: Select Momentary
looks better. Now use "image" field to set NSAddTemplate and NSRemoveTemplate. Make sure that label field is empty.
Ok, we have "+", "-" and one empty segment. To prevent the latest one to be selected by the user, select it from Segment: pop up and turn off Enabled check box (located next to State: label).
And lastly, what we have to do is set width of first two segments to make them square.
Go to Size inspector
Select Segment 0
Turn off "Fixed" checkbox (segment should immediately autoresize to fit image)
Select Segment 1 and repeat number 3
Now as you resize control, only last segment will change width
Put it at the bottom of your table view and resize as well.
Enjoy ;)
Update for OSX Yosemite
I tried to achieve the same look as Mail.app has in the Accounts view (right window on my screenshot).
I did achieve the desired result by following the steps below:
Add a NSSegmentedControl
Add two segments and set the image to each:
NSAddTemplate for the + button
NSRemoveTemplate for the - button
Set the size of the segments to fixed and set the value to 32 pixels
The rectangle next to the buttons is a NSButton with the style Gradient.
The Button is enabled but Refuses First Responder is set to true so that it is not clickable.
Use a NSButton with a gradient style, and for the images use the system provided NSAddTemplate and NSRemoveTemplate.
One answer here suggests using gradient buttons, however these buttons cannot be disabled as this causes the background to change and thus breaks the look. Another one suggested using a segmented control, which is almost perfect but segmented controls don't support autoresizing, e.g. if the table width is dynamic. My suggestion is a combination of both. Use a segmented control for the actual buttons and a gradient button to fill the rest of the table width that now can also be dynamic if the button width is dynamic as well.

I have an NSOutlineView which I draw badge numbers to the right side of cells using drawAtPoint:, NSAttributedString, and of course NSBezierPath. My problem exists when resizing of the outline view occurs when within a subview of an NSSplitView. The badges move along with the resize to the left or right. When they get to the text of the cells themselves they do not stop or truncate the text under them. It just flies right over.
Is there a way to have the cell recognize the custom drawn view next to it and truncate text accordingly? I have tried the solution PXSourceList already, but that did not help either.
"PXSourceList solution" working good. You subclass NSOutlineView and overload frameOfCellAtColumn for this particular task. At this function you need to decrease width of cellFrame, returned from super call, by the width of your badge plus padding.
Yeah, I did my homework and I found the setFrame:frame display:YES animate:YES but I don't understand how am I find out the height necessary to make it bigger or smaller. Let me exemplify: I'm making kind of spotlight search tool but when the user start the app it will just have a textfield (to type in the search keywords) and a button (Filter Settings) and the window fits the size of these two objects (NOTE: The window start position is on the center and on the top of the screen). When the user hits the "Filter Settings" button I want the window to make an animation going down and then showing the "check box group" that filters the search results.
In your case you need to find out the height of the check box group that you are adding to the view. An easy way to do this is to make a seperate view in your nib that contains the check boxes. Hook up the view to the window using IB, and when it is time to display the check boxes add that view to the windows content view and animate the window resize.
I could not find a way in the documentation to tell an NSButton to resize its image to fill up the whole button. Is there a way to do this programatically?
The closest you'll get is -setImageScaling: ... look up the constants to see how the image will be scaled within the button cell, given its bordered state and bezel type.
If you're looking to replace the standard button entirely with your image (ie, the button cell doesn't draw itself at all - your image serves as the entire visual representation), turn off the border (-setBordered:).
All of these options can be configured in IB as well. A tip: in IB, hover the mouse over any setting in the inspector panel - most if not all give you a hint that shows what method controls the behavior affected by the setting's control.
