|
875 |
|
|

|
876 |

|

|
878 |
|
|
* menuPtr's parent; since the menu uses override-redirect
|
879 |
|
|
* mode it will be in the *real* root window for the screen,
|
880 |
|
|
* so we have to map the coordinates from the virtual root
|
881 |
|
|
* (if any) to the real root. Can't get the virtual root
|
882 |
|
|
* from the menu itself (it will never be seen by the wm)
|
883 |
|
|
* so use its parent instead (it would be better to have an
|
884 |
|
|
* an option that names a window to use for this...).
|
885 |
|
|
* 2. The menu may not have been mapped yet, so its current size
|
886 |
|
|
* might be the default 1x1. To compute how much space it
|
887 |
|
|
* needs, use its requested size, not its actual size.
|
888 |
|
|
*
|
889 |
|
|
* Note that this code assumes square screen regions and all
|
890 |
|
|
* positive coordinates. This does not work on a Mac with
|
891 |
|
|
* multiple monitors. But then again, Tk has other problems
|
892 |
|
|
* with this.
