I am trying to move an old application developed in D7. I had to upgrade from an old version of Eldos to the most recent one as a first step to prepare a move to Delphi X10, but suddenly, all the TButtons, TBitmap, TEdit etc now have the old 3D style. While I could use Eldos replacements for many of those, not all of them can be replaced with Eldos versions.
How can I get the same appearance as before (flat look)? Is it simply a parameter or a global property that I have to change somewhere?
