| Ove Kaaven | e9b568c | 1999-02-28 11:27:26 +0000 | [diff] [blame] | 1 | My tests show that Windows window management events behave like described |
| 2 | in this file, at least under Win98. |
| 3 | The (16/32) or (16) or (32) at the end shows whether the sequence has been |
| 4 | confirmed for win16, win32, or both. |

| 6 | Window Edge Styles (Win95/98 look): |
| 7 | WS_EX_DLGMODALFRAME: double border, WS_CAPTION allowed |
| 8 | WS_DLGFRAME: double border, WS_CAPTION not allowed (but possibly shown anyway) |
| 9 | WS_THICKFRAME: thick border |
| 10 | WS_BORDER (default for top-level windows): single black border |
| 11 | none (default for child windows): no border |
