Summary
Allows other threads to generate main thread notifications.
Description
Use this component to allow other threads to generate main thread notifications.
Accessing user interface items such as Labels, Check Boxes, Buttons, etc. from a thread different than the main thread in windows is not safe and can lead to application crash.
TTLMainThreadEvent allows any thread to call an event in the context of the main thread where the code can safely access any user interface item.
To assign the event to be called use the OnNotify event to a callback function.
To generate the event call the Fire method.
If you need to wait until the event is processed set the Blocking property to True.
