Enables shared control of the message pump between Win32 and WPF in interoperation scenarios.
Assembly: WindowsBase (in WindowsBase.dll)
Although the class itself is static, all members of are specific to a particular thread. For example, if you examine the value of IsThreadModal on two different threads, you might get different values.
The methods are static but they are backed by per-thread data structures. The static methods allow singleton access but the is sorting out the appropriate per-thread operations.
The owner of the message pump is defined by the code that calls the Win32 function GetMessage. The owner calls RaiseThreadMessage for every keyboard message. This method raises the ThreadFilterMessage event with the messages contained in the event data. If that event is not handled, the owner raises the ThreadPreprocessMessage event with the messages contained in the event argument.
Only keyboard messages are supported.
