# MouseInfo by Al Sweigart al@inventwithpython.com

"""
Features we should consider adding:
* Register a global hotkey for copying/logging info. (Should this hotkey be configurable?)

Features that have been considered and rejected:

* The Save Log/Save Screenshot buttons should open a file dialog box.
* The Save Log button should append text, instead of overwrite it.
* The log text area should prepopulate itself with the contents of the given filename.
* The button delay should be configurable instead of just set to 3 seconds.

# Originally, these functions were pulled in from PyAutoGUI. However, to
# make this module independent of PyAutoGUI, the code for these functions
# has been copy/pasted into the following section:
# NOTE: Any bug fixes for these functions in PyAutoGUI will have to be
# manually merged into MouseInfo.
#from pyautogui import position, screenshot, size
# =========================================================================
# Alternatively, this code makes this application not dependent on PyAutoGUI
# by copying the code for the position() and screenshot() functions into this
