How do you set the absolute position of figure windows with matplotlib?

Question

I'm writing a simple Python application that uses matplotlib to display a few figures on screen. The number of figures generated is based on user input and changes throughout the application's life. The user has the ability to issue a "plot" command to generate a new figure window with the selected data series. In order to improve the user experience, I would like to provide another command that would programmatically arrange all open figure windows in some convenient arrangement (e.g. tile them across the available screen space).

I believe to have found APIs that allow me to adjust the size of the figure window (in pixels), but haven't had any success in finding a way to set their absolute position on screen. Is there a way to do this without delving into the details of whatever backend is in use? I would like to do this in a backend-agnostic way so I can avoid relying upon implementation details that might change in the future.

FINALLY found the solution for QT backend:

import matplotlib.pyplot as plt  fig, ax = plt.subplots() mngr = plt.get_current_fig_manager() # to put it into the upper left corner for example: mngr.window.setGeometry(50,100,640, 545) 

If one doesn't know the x- and y-width one can read them out first, like so:

# get the QTCore PyRect object geom = mngr.window.geometry() x,y,dx,dy = geom.getRect() 

and then set the new position with the same size:

mngr.window.setGeometry(newX, newY, dx, dy) 

I was searching quite often for this and finally invested the 30 minutes to find this out. Hope that helps someone.
