Swashbucklers with the Gymnast style gain panache when they Trip, Shove, or Grapple.
Does it have to be an actual Trip action, or would Improved Knockdown work?

While @BenBarden's answer was correct at the time of writing, the 3rd errata of the CRB changed Knockdown:
If you do and your Strike hits, instead of rolling a check for your Trip attempt, you automatically apply the critical success effect of a Trip.
So it gives panache to the Gymnast.
Trip, Grapple, and Shove are specific actions. You gain panache by pulling them off with flair. Thus, a Gymnast would get Panache from a successful Trip as part of a standard Knockdown, but not for the improved Knockdown, which applies the critical success effect of a trip, but does not otherwise behave as a trip. Likewise, you can gain panache from a successful use of the grapple action, but not from those actions that just automatically enter a grapple like Combat Grab.
However, it's worth noting that as a Swashbucker, you can also gain panache from Tumble Through, and from actions in general that are appropriately cinematic and daring.
