There's currently no set function for .label, only a get function. I added this to my extensions and it seems to work ok:

• TabbedViewTab{
  label_{ arg name;
  label= name;
  tabbedView.refresh();
  }
  }

I don't know how to make pull requests (yet) so hope it's ok that I just put it here.

Hi,

when specifying an index to add a new tab it adds itself at the right place but clicking around on the tabs in the GUI afterwards gives some strange behavior. Clicking tabs before and including the inserted index selects it as normal but clicking a tab at an index after the inserted tab selects the tab at an index-1. Dragging any tab and releasing it or adding a new tab without specifying an index seems to set it back to normal behavior.

This is only an issue with TabbedView2, not TabbedView. Tested on MacOS and Windows with QT.

To reproduce:

(
w= Window("tabs", Rect(0, 0, 600, 300)).front;
t= TabbedView2(w, Rect(20, 50, 550, 300));
t.add("tab1");
t.add("tab2");
t.add("tab3");
t.add("tab4");
t.add("tab5");
t.add("tab6");
t.add("tab7");
t.add("tab8");
t.add("tab9");
t.add("tabInsert", 4); // add "tabInsert" at index 4
)

Also, thanks a lot for this quark, I use it a lot :)
