Any possibility that Tabs will be added to Gui Edytor? If no, can I use button as Tabs? How then set it in code?

Check out the tutorial Advanced\1 - Geometry, Graphics, Gui, Misc, Net, Sound\Gui\03 - Tabs.cpp

But hi want to create tab in Gui Editor!
I' m too want to know how do that.
I think that I must create Region but next I don't know how it conwert to Tab.

i asked already better support for tabs. noone wanted to listen therefore i moved to another gui lib. i suggest you to do the same.

Tabs works just fine.. just look at the tutorial.. it shows how to make one very simple..

they work yes, but it is a simulation of tabs, not exactly real tabs. say we are making tabs in gui editor. each region of new tab would overlay previous tab. now imagine you have 10 tabs with 10th tab region on top, and you suddenly need to change contents of 1st tab. All 9 regions above 1st one will have to be moved. idk, to me it doesnt sound like "just fine", more like "it works, more or less"

If you don't like it.. don't use it. So like you said about moved to another gui lib, it's the only other option you have

Tabs is simple to do in code but anyway I think that in Gui Editor should be all types of gui.

it's on the roadmap

Ok, thanks for answer.
