system.nav.openWindow

This function is used in Python Scripting.

Description

Opens the window with the given path. If the window is already open, brings it to the front. The optional params dictionary contains key:value pairs which will be used to set the target window's root container's dynamic variables.

For instance, if the window that you are opening is named "TankDisplay" and has a dynamic variable in its root container named "TankNumber", then callingsystem.nav.openWindow("TankDisplay", {"TankNumber" : 4}) will open the "TankDisplay" window and set Root Container.TankNumber to four. This is useful for making parameterized windows, that is, windows that are re-used to display information about like pieces of equipment. See also: Parameterized Popup Windows.
