Open DProperty Sheets with buttons or labels?

There is no real documentation on this, but would could someone give me an example of how i would make a button or just a text box and then when it is clicked it changes tabs of the property sheet


local PropertySheet = vgui.Create("DPrope...")
blabla

local mytab = PropertySheet:AddSheet(blabllbalba)

PropertySheet:SetActiveTab( mytab )
