"""

|
A pure-Python Sizer that lays out items in a grid similar to
|
|
wx.FlexGridSizer but item position is not implicit but explicitly
|
|
specified by row and col, and row/col spanning is supported.
|
|
|
|
Adapted from code by Niki Spahiev.
|
|
|
|
NOTE: There is now a C++ version of this class that has been wrapped
|
|
as wx.GridBagSizer. It is quicker and more capable so you are
|
|
encouraged to switch.
