Hi
thanks for the answers, but I do not think it is applicable in this
situation.
In the application I have an event that triggered (e.g., a button is
pressed) the opening of the window by pylab.figure() and then the
application shows (via figure pylab.show()) it to the user. So, the user
defines when the figure will be closed. So, if I use pylab.close(1) in the
application, I cannot use pylab.show() afterwards in the code (because it
will be nothing to show...)
The only way I found to 'flush' the memory is via bind() based on the
'master' (e.g., master = Tkinter.Tk(), master.bind('<Destroy>',
self.close_showed_figures()) but it is already late for the application
because the memory leak is only of concern when 'master' does not destroyed.
Kind regards,
Tanja
