suspendApplication (X emulator applet)

Syntax

void suspendApplication()

Description

The suspendApplication method suspends or ends the current emulator session:

If the application is resumable, the session is suspended.
If the application isn't resumable, the session ends and the application exits.

Examples

<SCRIPT LANGUAGE="JavaScript">

window.onerror = trapError

function trapError(message, url, line) {
   alert("There's no X emulator session to stop");
   return true
}

function stopEmulator() {
   top.WebtopFrame.DisplayFrame.document.applets["Tarantella X Emulator"].suspendApplication();
   alert("X emulator session stopped");
}

</SCRIPT>

<FORM>
   <INPUT TYPE=button VALUE="Stop" onclick="stopEmulator()">
</FORM>

This example adds a button beneath the links on users' webtops. When a user clicks this button, Secure Global Desktop stops the current X emulator session, if one is running.

Add the code to the HTML document containing the webtop tray applet (left.html in the sco/tta/standard webtop theme), after the TTAAPPLET declaration.

Note This example assumes you are using the sco/tta/standard webtop theme. If you're using another theme, with different frame names and layouts, or different applet names, you'll need to modify the lines that invoke the suspendApplication method to access the X emulator applet used by your new theme.
