Body became transparent suddenly

[az.wincze13]

I was working on a model when all the bodies became transparent and only the edges were visible. Furthermore, in every other project I made before the bodies became transparent as well. What happened and how could I make the bodies appear solid again?

You accidentally turned on Wireframe display.  You can change it to another type display by selecting the Visual Style Controls.  Probably Ctrl+6 is what you want.
