Is that possible to reach something like on screen, using tab container and tabs? Like I want to have icons and texture buttons as a tabs nor just labels :

Yeah, sure. You can just create TextureButtons and they do whatever you want where you click them.

But can I just use texturebuttons in tabcontainer like a normal tabs nodes and they will work same?

Because when I set texturebuttons as a child of tabcontainer and I set textures for those buttons, they don't change, it just doesn't work

I've never used a TabContainer, but you can set visibility on normal Containers off and on and it will work like a TabContainer.
