                                 int flags)

Delegates the check to the underlying control link. (true if data types match and one is an entry, the other one an exit parameter)

Specified by:

canConnectFigures in class PolySplineConnection

Parameters:

startFigure - Proposed start figure

endFigure - Proposed end figure

flags - App-specific flags that may define constraints for the connection check

Handles the connection of a connection. Does nothing by default.

Overrides:

Parameters:

startFigure - Figure to connnect to

endFigure - Figure to connnect to

handleDisconnect

protected void handleDisconnect(CH.ifa.draw.framework.Figure startFigure,
                                CH.ifa.draw.framework.Figure endFigure)

Description copied from class: PolySplineConnection
