I am trying to get the PID of a window "A : Fluid Flow (Fluent) - Meshing" on the right side of this image. The commands that I have found are below. They don't work after I have clicked on the window. I want to kill the right side window which comes from the left side window "Test02 - workbench" without killing both windows. The right side window is obtained by double clicking on Mesh which is located between Geometry and Setup of the right side window. However, I am able to get the PID of the left side window.

With the last command wmctrl -mlpx, it seems that the PID is 5159 for the left side window and 0 for the right side window. How could it be 0?
