adding a tab view item

[regulus6633]

I can’t programatically add a new tab view item to my tab view. I tried…

Make new tab view item at end of tab view items of myTabView with properties…

Also I tried using call methods:

call method “addTabViewItem:” of myTabView with parameter “newTabLabel”

But that didn’t work, it seems I need to create a tab view item object before I can add it in this way, so I tried…

set newTabViewObject to call method “alloc” of class “NSTabViewItem”
set initTabViewItem to call method “init” of newTabViewObject
call method “addTabViewItem:” of myTabView with parameter initTabViewItem

But none of those worked… anybody know how to do this?

There is no scripting support in these custom classes, and they are not subclasses of NSTabView. Therefore, they do not understand your tab view command. See the documentation for this:

Inherits from
NSControl : NSView : NSResponder : NSObject

PSMTabBarControl is a subclass of NSControl, which doesn’t know anything about NSTabView.

If you want to use this, you will need to use Cocoa and Interface Builder. From the readme:

Simply drag a custom view object from the views palette in IB, read the PSMTabBarControl class into IB, and set the view’s custom class to PSMTabBarControl. Then connect the control’s tabview outlet to the tab view being controlled, and make the control the delegate of the tab view. You can also connect the control’s “partner view” outlet to another view that will resize in response to the hide/show behavior of the control.

To add this to an existing view programmatically, use -[PSMTabBarControl -initWithFrame:] as you would with any other NSView (and then set up your delegate and connections appropriately).

I saw this post from Mikey-San but it doesn’t seem right, or at least not current. He says it’s a custom class and not part of NSTabView, but I can use call methods from NSTabView to switch between tabs and delete a tab, so I don’t think this is correct any more.

I also tried to make the new tab view item using the initWithIdentifier: but again I couldn’t get it to work…

set newTabViewItem to call method “initWithIdentifier:” of class “NSTabViewItem” with parameter “anIdentifier”
call method “addTabViewItem:” of myTabView with parameter newTabViewItem

Maybe someone with obj-c experience can help me…

I have the idea to use an obj-c class to create the new tab view item since I can’t do it with call methods. So here’s what I’ve got but i get this error message: *** NSMapInsert(): attempt to insert notAKeyMarker

#1) what’s wrong with my code?
#2) what does that terror message mean anyway?

makeNewTabViewItem.h

#import <Cocoa/Cocoa.h>

@interface makeNewTabViewItem : NSTabViewItem
{

}

+(NSTabViewItem *)returnNewTabViewItem;

@end

makeNewTabViewItem.m

#import “makeNewTabViewItem.h”

@implementation makeNewTabViewItem

+(NSTabViewItem *)returnNewTabViewItem
{
NSTabViewItem *newTVI = [[NSTabViewItem alloc] initWithIdentifier:@“myIdent”];
return newTVI;
}

@end

================================================

Then back in applescript I want to say:
set newTVI to call method “returnNewTabViewItem” of class “makeNewTabViewItem”
call method “addTabViewItem:” of objMainTV with parameter newTVI

BUT IT DOESN’T WORK!!! It’s so frustrating. I get that unintelligible error that I have no idea what it means. So any help would be appreciated because it’s just as frustrating as that error to be talking to myself on here.
