infoframe.py
Released under wxWindows license etc.
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
couple of buttons for controlling the echoing of all output to a file
with a randomly-chosen filename... [[A LITTLE MORE COULD BE SAID
HERE]]
Typical usage:
from wxPython.lib.infoframe import *
... # ... modify your wxApp as follows:
class myApp[wxApp):
outputWindowClass = wxInformationalMessagesFrame
...
If you're running on Linux, you'll also have to supply an argument 1 to your
constructor of myApp to redirect stdout/stderr to this window (it's done
automatically for you on Windows).
If you don't want to redirect stdout/stderr, but use the class directly: do
it this way:
InformationalMessagesFrame = wxInformationalMessagesFrame\
([options from progname (default ""),
txt (default "informational
messages"])
#^^^^ early in the program
...
InformationalMessagesFrame([comma-separated list of items to
display. Note that these will never
be separated by spaces as they may
be when used in the Python 'print'
command])
The latter statement, of course, may be repeated arbitrarily often.
The window will not appear until it is written to, and it may be
manually closed by the user, after which it will not appear again
until written to... Also note that all output is echoed to a file with
a randomly-generated name [see the mktemp module in the standard
library], in the directory given as the 'dir' keyword argument to the
InformationalMessagesFrame constructor [which has a default value of
'.'), or set via the method SetOutputDirectory...
Please also note the methods EnableOutput and DisableOutput, and the
possible arguments for the constructor in the code below... (* TO DO:
explain this here...*) The former, EnableOutput, displays the frame
with an introductory message, opens a random file to which future
displayed output also goes, and sets the __debug__ variable of each
module whose name begins with a capital letter {this happens to be the
author's personal practice; all my python module start with capital
letters} to 1. This is so that you can say
if __debug__:
InformationalMessagesFrame("... with lots of %<Character> constructs"
% TUPLE)
without worrying about a huge about of overhead in the case where
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.
The DisableOutput method does the reverse of this; it closes the
window (and associated file), and sets the __debug__ variable of each
module whose name begins with a capital letter {this happens to be the
author's personal practice; all my python module start with capital
letters} to 0. It also enables/disabled the appropriate menu items,
if this was done previously (or SetOtherMenuBar has been called...).
Finally, note that the file-like method close() destroys the window
(and any associated file) and there is a file-like method write()
which displays it's argument [actually, it's very similar to
DisableOutput). Also, class instances are callable as noted above,
displaying successive arguments if this is done.
