| # For Windows systems with more than one monitor the available screen area may |
| # have negative positions. Geometry settings with negative numbers are used |
| # under X to place wrt the right or bottom of the screen. On windows, Tk |
| # continues to do this. However, a geometry such as 100x100+-200-100 can be |
| # used to place a window onto a secondary monitor. Passing the + gets Tk |
| # to pass the remainder unchanged so the Windows manager then handles -200 |
| # which is a position on the left hand monitor. |
| # I've tested this for left, right, above and below the primary monitor. |
| # Currently there is no way to ask Tk the extent of the Windows desktop in |
| # a multi monitor system. Nor what the legal co-ordinate range might be. |
