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 Smile 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 Smile

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,
Honza

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.

Well I have to disagree with undogs,

TabCtrl can have buttons tied to them, all you have to do is the following:

Button closeButton;
...
tabs.Add( myTabInstance, img, "tabName").SetCtrl(closeButton);


All you have to do is set the correct style to the closeButton and you're done with it Wink

Sure, but it's not a "direct close button feature" Smile

Sure, but most users think that you can't add buttons to TabCtrl, so I thought a little reminder wouldn't do any harm Smile
