screen update

Hello, my problem is: An application displays information about the contents of a table on the screen. How can the application get the information when the table is updated by another application? This is necessary to update the screen. Is it possible to avoid polling? -------------------------------------------------------------------------------- Hanno Ridder Universitaet Koblenz-Landau Institut fuer Softwaretechnik Tel: 0261/9119-422 Rheinau 1 Fax: 0261/9119-499 56075 Koblenz Mail: ridder@informatik.uni-koblenz.de
