Showing an Invisible Form

When running multiple desktops on a workstation, switching to another desktop hides all forms on the prior desktop, which then generates a warning message box advising you that the GUI application (that is, ApplicationType_GUI) has no visible forms.

As GUI applications can run without a visible form, the Show an invisible form command in the Jade User Interrupt submenu enables you to terminate the application by using the system tray icon.

By default, the Show an invisible form command is disabled in the Jade Interrupt menu.

To display the first invisible form for a GUI application when running multiple desktops

  1. Click on the system tray icon to display the application name followed by - no visible forms (for example, LockTest (4) – no visible forms).

    The Jade User Interrupt submenu is then displayed, with the Show an invisible form command enabled.

  2. You can then perform one of the following actions.

    • Select the Terminate Application command, to terminate the application. (For more details, see "Terminating an Application".)

    • Select the Show an invisible form command, which displays the first invisible form for the application.

If the ShowUserInterrupt parameter in the [Jade] section of the JADE initialization file is set to false, this command is ignored and an icon is displayed in the system tray if the application does not have a visible form.
