TPJCBView is a non-visual Delphi component that notifies the user whenever the content of the clipboard changes.
Notification is by means of an event. By handling the event your application can respond to changes on the clipboard. The component can be used as the heart of a program that displays "live" information about the clipboard. Alternatively it can be used to enable and disable other components whose state depends on the available clipboard formats.
TPJCBView provides an Enabled property that is used to enable and disable the component and hence it's events. It also has a TriggerOnCreation property that triggers an event when the control is created.
A demo program with an associated explanatory read-me file is included in the download. The demo enables and disables a button depending on whether the clipboard contains text. It can also display clipboard text in a memo.
