Class SecurityDialogMessageHandler

java.lang.Object

net.adoptopenjdk.icedteaweb.client.parts.dialogs.security.SecurityDialogMessageHandler

All Implemented Interfaces:

Runnable

public class SecurityDialogMessageHandler
extends Object
implements Runnable

Handles SecurityDialogMessages and shows appropriate security dialogs.

In the current architecture, SecurityDialogs are shown from a different AppContext than the AppContext that asks for a security prompt. This ensures that all security prompts are isolated and their Look and Feel is not affected by the Look and Feel of the applet/application.

This class contains allows a client application to post a SecurityDialogMessage. When this class finds a security message in the queue, it shows a security warning to the user, and sets SecurityDialogMessage.userResponse to the appropriate value.
