KB-35479: Closing two windowed screens at the same time.

Question:

How can I close two windowed screens at the same time?

Solution:

To do so, follow these steps:

Create an internal tag in the Viewer called ScreenControl;
Create three screens: InitialScreen, Screen1 (windowed), and Screen2 (windowed);
On InitialScreen, create a button to call Screen1. On this button, you must create an OpenScreen pick and set a nonexistent name to the frame where the Screen1 will open;
On Screen1, perform the same settings of the previous exercise to call Screen2;
On Screen2, create a button to close both Screen1 and Screen2. On the button, create a script that sets ScreenControl tag’s value as True, and use Screen2’s Close method;
On Screen1, you must create a user event that is activated when ScreenControl tag’s value is True. In this event, create a script that sets ScreenControl tag’s value as False and use Screen1’s Close method.

See the attached sample application for further details.
