Hey guys,
I just tried to fix the multi-screen bug mentioned here:
http://www.amsn-project.net/forums/viewtopic.php?p=23738 ... but I think we
won't be able to fix this. The problem is, that always after creating a
window the proc moveinscreen is called that places the window on the primary
screen again. So we need to get the whole geometry of all screens. Therefor
[winfo screenwidth .] is useless, it always returns the width of the primary
screen, independant of where the window to check is positioned. A call of
[wm maxsize .] returns the geometry of all screen, but we only get the
complete geometry, not only of one screen, and we don't get where the other
screen(s) is/are positioned. It always returns the absolute size, but if the
second screen is positioned left beside the primary screen, we would need
negative coordinates to successfully move a window on that screen, but this
information doesn't tell us anything about that. The other problem would be
that we get "dead corners" in the case that the screens have different
resolutions: The [wm maxsize .] merges the screens into one big rectangle,
so there will be at least one corner that no screen can display. So we need
another solution or we are unable to fix that bug. Does anyone have an idea
how to be able to get the resolution and position of the other screens? I
only found one article about that problem telling that tcl doesn't seem to
support it and it uses some kind of dirty hack to detect how many screens
are used but it doesn't really help. One way would be to let the user
manually enter his screens and the fitting geometry or letting him turn off
the moveinscreen-proc. Both ways are very user-unfriendly and not really
safe but it would be a last resort ...
