Having wrestled with NSPopUpButton in a previous question here I am now trying to place a NSPopUpButton inside an NSToolbar. Essentially I want to create something similar to what XCode has by default on the left hand side of it's toolbar. E.g. a pop up button with an action button next to it.
I have seen a method that show's a programmatic way of creating an NSPopUpButton and then adding it to an NSToolbar, but then I can't work out how to do all the Binding stuff that was so handy last time.
Interface Builder hasn't been very helpful, so any help gratefully received.
P.S. Could I solve this by creating a custom view (containing an NSPopUpButton with the usual bindings) and then adding the custom view to the toolbar?
It's actually pretty easy to do what you want here. In Interface Builder, switch to the tree view (the second button on the View Mode segmented control). Expand the window and the toolbar. Then, from the library, drag a popup button onto the toolbar. Interface Builder will embed a new popup button in a custom view for you automatically.
To actually put the button on the toolbar, double click on the toolbar in the window. This will bring up the customization sheet. You can drag the popup button to the desired location on the toolbar.
If you wanted to do this programmatically, you would create a custom view containing your popup button. Then, you'd need to assign it to a new outlet so you can refer to it programmatically. In the toolbar:itemForItemIdentifier:willBeInsertedIntoToolbar method, you would create a new NSToolbarItem per usual, and call setView: to assign the custom view to the toolbar item.
Old post, but note you can also double-click the toolbar in the window and drag straight into the "Allowed Toolbar Items".
You will want to open up the toolbar view anyway so you can drag things in or out of the default toolbar items.

How can I detect when the menu in menu bar is clicked? I mean when whatever is clicked like for example "file" menu not a concrete position in the menu.
I tried to connect IBActions from menu items in interface builder from my code, but it does not work from the main menu item like "File" only from the submenus within this menu
First of all, what are you trying to achieve in the big picture? Perhaps knowing when the menu bar has been clicked is not the best approach.
You might be able to achieve what you're interested in by observing the NSMenuDidBeginTrackingNotification notification, but it's hard to tell. For example, this will fire for keyboard-initiated tracking, too.
Go to MainMenu.xib and look at the menu layout. It will be something like
Main Menu
Menu Item - File
Menu - File
Right click on The NSMenu you want to observe, not the NSMenuItem. attach the delegate to an object or controller of your choosing.
Then implement
- (void)menuWillOpen:(NSMenu *)menu
So when I add an NSPopUpButton in Xcode's Interface builder, it automatically has 3 options in the dropdown which can be worked with in the IB; however, I want to have 8 options in my popup. I know I can just add these in code, but it would be much more convenient if there was a way to add them right in the IB, without making the popup button a property. Is there any way to do this?
If you expand the NSPopupButton, there is a "Popup Button Cell". Expand that and you will find a "Menu". You can drag new NSMenuItems to that menu in Interface Builder.
Sorry for the complicated title, but it's hard to explain.
This is the hierarchy I have:
Custom View
Custom View
Push Button
Box
WebView
WebView
The way my code works, is that the 'Box' has a 'setContentView' to one of the 2 WebViews shown above. So basically the Box can have a different WebView at any time.
I have the Push Button, which I want to assign to 'Go Back' on the WebView. But I need this button to 'Go Back' on the WebView which is within the Box.
So whenever the WebViews are switched around, the Push Button should link itself to whichever WebView is in the Box, and visaversa.
Is this even possible?
Thanks in advance everyone!
If you had an IBOutlet for your box (called theBox) defined in whichever custom view your button's action method is in, you can just use this in that action method:
[(WebView *)self.theBox.contentView goBack];
So whenever the WebViews are switched around, the Push Button should
link itself to whichever WebView is in the Box, and visa versa.
Why not use a more conventional arrangement? Make the view controller the button's target, and have the action in the view controller take whatever action is appropriate. In this case, that would be adding the appropriate web view to the box.
Views normally don't know anything about how the application works. They just do what the controller tells them to do.
I'm using Objective-C and Cocoa, whilst developing for Mac OS X - so not the iPhone/Cocoa Touch. (That said, I'd be interested if it was the same procedure for the iPhone)
I'm working on a preferences window for a simple app. I have a NSWindow with a toolbar - there are 5 different items on the toolbar, all of which need to bring up a different set of options.
So I set the NSToolbar and its items in Interface Builder, and then placed a custom view underneath the menu - taking up the rest of the window. My plan is to work out the interface too each of the NSToolbarItems options, and then draw the corresponding view on to the custom view when the specified NSToolbarItem is clicked.
I'm guessing that I simply create a NSView sub-class for each view, an empty xib in Interface Builder - set the xib to my custom NSView, code it as usual... But here's a few problems;
1 - Just how can I get the xib file to appear on the custom-view then? I have looked around and most articles don't seem to have this situation, or a situation I can relate too.
2 - When the window comes up, I want the default view to appear on the custom view. Once again, I'm guessing I just write that in the initialisation code for the NSWindow - its no big deal. It just goes back to question 1 though - how do I draw my NSView to the custom-view specified in Interface Builder?
I'd be really grateful for any help!
Cheers in advance.

You can't have a menu inside of a window. You can have a pop-up button, which has a menu, but not a menu directly. Did you mean “toolbar” here?
You don't need to create a custom view for this. Make a tab view and set it to be tabless. Give it as many tab view items as you have toolbar items. In your controller, write an action method for each of the toolbar items, and in each action method, switch the active tab of the tab view.
You can activate different tabs in IB to populate them with views in IB. The active tab is saved in the nib, so make sure you set it back to the first tab before saving, so that the first tab is the one that's initially active when your app runs.
Just how can I get the xib file to appear on the custom-view then?
That question doesn't make sense.

You would only be able to do that if you have your own initialization code for the window, which you would only have if you have subclassed NSWindow. There are very few reasons to do that; unless you're making the window itself look different (not making an Aqua or HUD window), you should move that initialization code elsewhere, probably to the aforementioned controller (which should be the File's Owner of the nib).
It just goes back to question 1 though - how do I draw my NSView to the custom-view specified in Interface Builder?
A custom view in Interface Builder is a plain NSView (unless you explicitly change it to a subclass of NSView you create). However, you do not need one for anything you have described in your question.
I have the following code:
AXWindowController *controller = [[AXWindowController alloc]
initWithWindowNibName:#"ActivateWindow"];
[controller showWindow:nil];
How do I use controller to make changes to the window ActivateWindow (eg. changing text on the window, etc.)? Step by step instructions would be appreciated. Thanks!
Well, none of the actual window elements are handled in your piece of code, your code just initializes and shows the window. (I've just had a quick scan through, so I'm assuming that it works)
If you want to, for example, display text in a window, the simplest way is to use an NSTextField.
Very simple instructions:
Drag and drop a Label item from the Interface Builder library into your window.
Drag and drop a button item from the Interface Builder library into your window.
In XCode, in your window controller, create an IBOutlet for your label, e.g. messageLabel
In XCode, in your window controller, create an IBAction for your label, e.g. changeLabel
In Interface Builder, drag and drop an "object" into your document. (Shortcut = CMD + 0)
Under the Identity tab, change the class to AXWindowController. (Shortcut = CMD + 6)
Ctrl + drag from the object to the label, choose the outlet messageLabel.
Ctrl + drag from the button to the object, choose changeLabel.
Now, to display text when you press the button, you would add code to the changeLabel IBAction to do so.
e.g. [messageLabel setTitleWithMnemonic:#"blah"];
And Finally, if you want it to automatically display text, you might as well just change the label content in Interface Builder / place the code in the windowDidLoad method in your controller.
That to me is pretty much the simplest way for you to do it. However, I recommend you read some books / tutorials on Cocoa and Objective-C before delving into harder stuff.
You'd programmatically make changes to your window in the code for your window controller, of course. Open AXWindowController.m and do whatever it is you're wanting to do. It's hard to give a more definite answer without knowing exactly what you're trying to do (if you just want to create the interface, use Interface Builder) or what your experience level is.
