This is a fairly rudimentary, but slightly fancier tha
wxPyOnDemandOutputWindow (on which it's based; thanks Robin), version
of the same sort of thing: a file-like class called
InformationalMessagesFrame.. This window also has a status bar with a
wxInformationalMessagesFrame. This window also has a status bar with a
couple of buttons for controlling the echoing of all output to a file
with a randomly-chosen filename... [[A LITTLE MORE COULD BE SAID

with a randomly-chosen filename...
The class behaves similarly to wxPyOnDemandOutputWindow in that (at
least by default) the frame does not appear until written to, but is
somewhat different in that, either under programmatic (the
DisableOutput method) or user (the frame's close button, it's status
bar's "Dismiss" button, or a "Disable output" item of some menu,
perhaps of some other frame), the frame will be destroyed, an
associated file closed, and writing to it will then do nothing. This
can be reversed: either under programmatic (the EnableOutput method)
or user (an "Enable output" item of some menu), a new frame will be
opened,And an associated file (with a "randomly"selected filename)
opened for writing [to which all subsequent displayed messages will be
echoed].
Please note that, like wxPyOnDemandOutputWindow, the instance is not
itself a subclass of wxWindow: when the window is open (and ONLY
then), it's "frame" attribute is the actual instance of wFrame...
Typical usage:

class myApp[wxApp):
outputWindowClass = wxInformationalMessagesFrame

written to, like wxPyOnDemandOutputWindow.
The former, EnableOutput, displays the frame with an introductory

goes (unless the nofile attribute is present), and sets the __debug__

debugging is not turned on. "Debug mode" can also be turned on by
selecting the item-"Enable debugging output" from the "Debug" menu of
a frame which has been either passed appropriately to the constructor
of the wxInformationalMessagesFrame (see the code), or set via the
SetOtherMenuBar method thereof. (I have found this to be an extremely
useful tool, in lieu of a full wxPython debugger...) This menu item
is also disabled, and an item "Disable debugging output" (which calls
the method described in the next paragraph) is enabled. Note that
these things need not be done: e.g., you don't need to have a "Debug"
menu with appropriate items; in this case simply do not call the
SetOtherMenuBar method or use the othermenubar keyword argument of the
class Instance constructor.
without worrying about the overhead of evaluating the arguments, and

"Debug mode" can also be turned on by selecting the item-"Enable

Finally, note that the file-like method close() destroys the window
