If size of MaskedTextCtrl lower then mask's length, then it show tail of
value instead of head.
For example:
length = 256 # db column length
mask = 'C{' + int(length) + '}'
formatcodes = '_<'
size = (GetTextExtent('M' * 60)[0], -1) # max field width - 60 symbols
SetValue('qwert')
It is show control with empty value. Because it show the end of value
padded by spaces. If press Home key in it - head of value will showed.
ShowPosition(0)
Hasn't effect.
