Summary:

pageChangeWindowMessageFilter is a function in the Microsoft Windows operating system that filters window messages sent to a window. It is typically used to prevent certain types of window messages from being sent to a window, or to modify the behavior of the window in response to a message.

For example, a program may use pageChangeWindowMessageFilter to block mouse events from being sent to a window, or to modify the way that the window responds to keyboard input.

pageChangeWindowMessageFilter is typically called from within the window procedure for a window, and is passed a message identifier and a message parameter. The function returns a value indicating whether the message should be allowed to be sent to the window or not.
