The meaning is the following:
Creates a transparent window at the edge of the screen, 1 pixel wide at full length. The window can be created from any of the 4 sides. When I hover over this transparent window, the WM_NCHITTEST event comes. It creates a popup window and checks every 400 milliseconds that the cursor is within the popup window. As soon as the cursor leaves the window, then after 400 milliseconds, the code for smoothly increasing transparency is executed until it becomes invisible and then the window is hidden.
At the moment WM_NCHITTEST is called all the time and I don't understand why. If I take another example with WM_NCHITTEST, then it can be seen that events only come when the cursor is over the window.
