[Pythoncard-users] changing wx.mixins

[tjerk h. <tj...@br...>]

An irritating behaviour of MultiColumnList are that they seem to sort=20
columns always like strings.  And if you put integers  in the =
MultiColumnList.items you get
errors so you have to change every thing to strings.(?)
So when you have a column with 'numbers' like  88,125,9,2
and click on the ColumnHeader it sorts thus  9,88,2,125
wich is mostly useless.
So now I changed some lines in the mixins from wx.
If anybody also wants a different sort behaviour do this.
In wx.lib.mixins.lstctrl change this lines in=20
__ColumnSorter(self,key1,key2):
    col =3D self._col
        ascending =3D self._colSortFlag[col]
        item1 =3D self.itemDataMap[key1][col]
        item2 =3D self.itemDataMap[key2][col]

        #--- Internationalization of string sorting with locale module
        if type(item1) =3D=3D type('') or type(item2) =3D=3D type(''):
            cmpVal =3D locale.strcoll(str(item1), str(item2))
        else:
            cmpVal =3D cmp(item1, item2)

lines added underlined

    col =3D self._col
        ascending =3D self._colSortFlag[col]
        item1 =3D self.itemDataMap[key1][col]
        item2 =3D self.itemDataMap[key2][col]

        #--- Internationalization of string sorting with locale module
        if type(item1) =3D=3D type('') or type(item2) =3D=3D type(''):
            if item1.isdigit() and item2.isdigit():
                cmpVal=3Dcmp(float(item1),float(item2))
            else:
                cmpVal =3D locale.strcoll(str(item1), str(item2))
        else:
            cmpVal =3D cmp(item1, item2)
      =20

So now the MultiColumnList recognizes numbers in the column, and sort =
according=20
to value...so  88,125,9,2  turns into 125,88,9,2


Any comments?
