Hello!
1) How do I use the same layout (created by Layout editor) to create multiple tabs?
* I tried tabctrl.Add(tab) but it only shows the contents 1 time, then I get empty tabs.
2) How do I add a close button to the tabs similar to what TheIde does?
Thanks

You don't  TabCtrl doesn't have such a feature. TheIde uses TabBar control. TabBar if far more advanced. You can add not only a close button but whatever you want. The goal was to integrate TabBar with TabCtrl but as usual there was something more important to do. But that would allow to have tabs on any side (not only on the top), one could also change tab position simply by dragging it.
Unfortunately this is still on to do list
PS: It's quite easy to emulate tabctrl behavior with TabBar. Simply switch views on tab change event.

Each widget can be added only once. Second call of Add() removes Ctrl from its previous parent before adding to a new one. This applies to all Ctrls, not only tabs. If you want to have the same thing in two locations, you have to create two instances of it. E.g.:WithMyLayout<ParentCtrl> tab1;
WithMyLayout<ParentCtrl> tab1;
tabctrl.Add(tab1);
tabctrl.Add(tab2);
Best regards,

Thanks!
I got the behaviour I wanted with:
// init code
int tabcount = 0;
WithMyTabLayout<ParentCtrl> tab[5]; // here I set how many I want
// code to add:
tabctrl.Add(tab[tabcount], "Tab " + AsString(tabcount));
++tabcount;
//code to remove:
tabctrl.Remove(tab[tabcount]);
--tabcount;
Besides that I just add ifs to check if 0 >= tabcount < 5, so I don't go out of the array boundaries.
