"""
function wrappers for wxPython system dialogs
Author: Kevin Altis
Date:   2003-1-2
Rev:    3

This is the third refactor of the PythonCard dialog.py module
for inclusion in the main wxPython distribution. There are a number of
design decisions and subsequent code refactoring to be done, so I'm
releasing this just to get some feedback.

rev 3:
- result dictionary replaced by DialogResults class instance
- should message arg be replaced with msg? most wxWindows dialogs
  seem to use the abbreviation?

rev 2:
- All dialog classes have been replaced by function wrappers
- Changed arg lists to more closely match wxWindows docs and wxPython.lib.dialogs
- changed 'returned' value to the actual button id the user clicked on
- added a returnedString value for the string version of the return value
- reworked colorDialog and fontDialog so you can pass in just a color or font
    for the most common usage case
- probably need to use colour instead of color to match the English English
    spelling in wxWindows (sigh)
- I still think we could lose the parent arg and just always use None

class DialogResults:
    def __init__(self, returned):
        self.returned = returned
        self.accepted = returned in (wx.ID_OK, wx.ID_YES)
        self.returnedString = returnedString(returned)

    def __repr__(self):
        return str(self.__dict__)

def returnedString(ret):
    if ret == wx.ID_OK:
        return "Ok"
    elif ret == wx.ID_CANCEL:

    elif ret == wx.ID_YES:
        return "Yes"

## findDialog was created before wxPython got a Find/Replace dialog

## modeless and so doesn't lend itself to a function wrapper
