Sub Window

It is possible to handle multiple windows since Ver.2.6.
When SmartSignage is started, the first thing that is displayed is the “Main Window”.
In the main window, you can create a new window. This newly created window is a “Sub Window”. This section describes how to create and manage the Sub Window.

If you open multiple windows, the message “Two or more SmartSignage windows are open” will be displayed in the center of the window. Click the “OK” button to turn off the display.
To hide this, you need to register the SmartSigange + Plus license key.
Note: The SmartSignage license key and the SmartSignage + Plus license key are different.
Note: The license key should be purchased. Please visit the SmartSignage website.

Attention about the operation of the Sub Window and the Main Window

The Sub Window is started from the Main Window, but the Sub Window does not close when the Main Window closes. This can be a problem if you launch the Main Window while the Sub Window is running.
When using on Windows, it is possible to relaunch the main window. Since the same application cannot be started normally on macOS, the Main Window cannot be started later if the Sub Window is running. If you want to launch the Main Window later on macOS, open a terminal and use the following command:

open -n /Applications/SmartSignage.app

You can launch a running app separately by adding the -n option to theopen command as described above.
