I’m working on a set of If statements to relocate some buttons according to my screen resolution. This would not be as much of a big deal if I didn’t have dual monitors…but I do and I’m not giving them up for this! So I’m going to have to reconcile the differences between the theme (Saphardana) and my monitors. :)

My monitors are currently set to 1280x1024 and the line of code I changed to relocate this button works correctly…

*Shortcut "Internet Browser" 1253 -22 spacer3.png spacer4.png .none #2TO !execute ["$Browser$"]

…(just to clear this up before one asks, I using 1253 instead of -27 because my screen width is not 1280, but its 2560 b/c of the dual monitors) Well that works if I don’t change my screen resolution, but I like to change my resolution to accommodate what I’m working on like CAD or PhotoShop. So I wanted to create some If statements to make my life easier. Here is what I wrote…

*Shortcut "File Manager" 12 -22 spacer3.png spacer4.png .none #2TO !execute ["$FileManager$"]
If ResolutionX = 800
*Shortcut "Internet Browser" 773 -22 spacer3.png spacer4.png .none #2TO !execute ["$Browser$"]
If ResolutionX = 1023
*Shortcut "Internet Browser" 996 -22 spacer3.png spacer4.png .none #2TO !execute ["$Browser$"]
If ResolutionX = 1152
*Shortcut "Internet Browser" 1125 -22 spacer3.png spacer4.png .none #2TO !execute ["$Browser$"]
If ResolutionX = 1280
*Shortcut "Internet Browser" 1253 -22 spacer3.png spacer4.png .none #2TO !execute ["$Browser$"]
If ResolutionX = 1600
*Shortcut "Internet Browser" 1573 -22 spacer3.png spacer4.png .none #2TO !execute ["$Browser$"]
EndIf

…The result of this code ends up making the spacer3.png button disappear. I modlded my code after the authors code that changed the BottombarXXX.png file according to the resolution. His looked like this…

If ResolutionX = 800
*Shortcut "" 56 2 Topbar800.png .none .none #1 !None
*Shortcut "" 2 -22 Bottombar800.png .none .none #2 !None
ElseIf ResolutionX = 1024
*Shortcut "" 56 2 Topbar1024.png .none .none #1 !None
*Shortcut "" 2 -22 Bottombar1024.png .none .none #2 !None
ElseIf ResolutionX = 1152
*Shortcut "" 56 2 Topbar1152.png .none .none #1 !None
*Shortcut "" 2 -22 Bottombar1152.png .none .none #2 !None
ElseIf ResolutionX = 1280
*Shortcut "" 56 2 Topbar1280.png .none .none #1 !None
*Shortcut "" 2 -22 Bottombar1280.png .none .none #2 !None
ElseIf ResolutionX = 1600
*Shortcut "" 56 2 Topbar1600.png .none .none #1 !None
*Shortcut "" 2 -22 Bottombar1600.png .none .none #2 !None
EndIf

…So my first question is, can anyone tell me what I’m doing wrong? And/Or is there some way I can have Litestep do some math like taking the screen resolution and dividing it by 2, and then subtract 27 ([R/2]-27)? That would be the best way because I could not have to do as much to make it work. ;-)

Thanks for your help,

Something like this might work:
(there's only one action so !execute [] is not needed but can still be there)

Test things like
!alert "$(10-2)/4+1$"
!alert "$ResolutionX/2$"
, etc.

$resolutionX/2-27$ should get you your desired result. another option would be to use the C flag for X/Y coordinates. This will automagically start you in the middle...but you would need to double 27 to make it work.

ie. $ResolutionX-54$C

$ResolutionX$ = width of primary monitor alone

Negative coordinates and C depend on how the module deals with multiple monitors. I'm pretty sure shortcut2 does use desktop coordinates (ie, -0 = far right of all monitors), which would make -27C = $ResolutionX-27$ if your second monitor has the same x resolution and is to the right of your primary.

But I think the problem with your code is that you must have a matching EndIf for each If. Otherwise try changing all but the first If to ElseIf, as in the example. (but tnl's code should work)

when $Resolution $ was originally put in it was the total of all resolutions. From what I can tell though that is still true.

Is there some way for LS to tell if there are 2 mons? I was thinking of writing some IF commands that would compare the total X and the total Y to help determin if there were 2 mons, but if there was some way to...

If dualmon
do ABC
If singmon
do XYZ
Endif

ElseIf! Don't do If ... If ... EndIf. And that's not enough, there could be 3 monitors, and you need to know how they are arranged if you're going to make any use of them anyway.

dev:
SM_CXSCREEN is primary monitor, SM_CXVIRTUALSCREEN is whole desktop. I do remember it being the total size, but if they're still that way it's only because that specific video driver is lying to Windows.
