| My tests show that Windows window management events behave like described |
| in this file, at least under Win98. |
| The (16/32) or (16) or (32) at the end shows whether the sequence has been |
| confirmed for win16, win32, or both. |
| |
| Window Edge Styles (Win31 look), in order of precedence: |
| WS_EX_DLGMODALFRAME: double border, WS_CAPTION allowed |
| WS_THICKFRAME: thick border |
| WS_DLGFRAME: double border, WS_CAPTION not allowed (but possibly shown anyway, untested) |
| WS_BORDER (default for overlapped windows): single black border |
| none (default for child and popup windows): no border |
| |
| Window Edge Styles (Win95/98 look), in order of precedence: |
| WS_EX_DLGMODALFRAME: double border, WS_CAPTION allowed |
| WS_THICKFRAME: thick border |
| WS_DLGFRAME: double border, WS_CAPTION not allowed (but possibly shown anyway) |
| WS_BORDER (default for overlapped windows): single black border |
| none (default for child (and popup?) windows): no border |
| |
| Win31 look, system metrics relations: |
| CYFRAME = 5, thick border, includes both edges (the colored inside is thus 3 pixels) |
| CYDLGFRAME = 4, double border |
| CYBORDER = 1, thin border |
| CYCAPTION = 20, includes both borders (the colored inside is thus 18 pixels) |
| CYMENU = 18, does not include any borders |
| CYHSCROLL = 17, includes both borders (the colored inside is thus 15 pixels) |
