Can you be more specific?

The FPCanvas.FloodFill(x,y) is not implemented in the LCL. It
"reintroduces" another FloodFill(X, Y: Integer; FillColor: TColor;
FillStyle: TFillStyle). This means the compiler message is correct.

The "find declaration" ignores the "reintroduce" and finds more than
the compiler.

Just add the two parameters.

Keep in mind that FloodFill can be very slow.
