| 27 | This sizer provides an empty buffer on one or more sides of it's | |
| 28 | contents. It can only hold a single widget, but that can be a | |
| 29 | sizer containing other items if you wish. | |
| 30 | ||
| 31 | The sizer is constructed with a parameter specifying which sides | |
| 32 | should have the border. You can use a logical OR of the following | |
| 33 | values to specify the sides: | |
| 34 | ||
| 35 | wxNORTH -- the top side | |
| 36 | wxSOUTH -- the bottom side | |
| 37 | wxEAST -- the right side | |
| 38 | wxWEST -- the left side | |
| 39 | wxALL -- all sides | |
| 40 | ||
| 41 | The width in pixels of the border is specified when the child | |
| 42 | widget is Added to the sizer. | |

| 102 | # TODO... Make an abstract class wxBorder whose decendants can be added to | |
| 103 | # a wxBorderSizer to provide drawing for the buffer area. Ideas are | |
| 104 | # to provide a color border, beveled borders, rounded borders, etc. | |
