[Solved] Calendar Date Position Drift

[Kaelri]

I've got one for you guys.

This issue arose after I modified limpet's Calendar skin to use an adjustable variable for the width of the skin. The X position of each meter is based on two variables: #FirstX#, which is used by the first date in the row, and #SpacingX#, which is used by each subsequent date (as in X=#SpacingX#r).

Code: Select all

FirstX=38
SpacingX=((#SidebarWidth#-#FirstX#-19)/6)

I also have a pair of meters which indicate the current date. One is is a STRING meter with formatting identical to the regular dates, except that it's bold. The other is a small solid-color IMAGE meter. The X position of both of these meters is a dynamic measure, based on the day of the week (0 = Sunday, 1 = Monday, etc).

Code: Select all

[msWeekDay2]
Measure=CALC
Formula=#FirstX#+msWeekDay*#SpacingX#

The problem is this: as the week goes on, the value of [msWeekDay2] shows an increasing drift to the right (i.e. a higher X) relative to the regular date meters.






I believe this is some sort of rounding error. If I calculate SpacingX by hand - in this case, with a total #SidebarWidth# of 500, the value of SpacingX comes to 73.83333 - the same error occurs. If I manually round it off to 74, it displays correctly. However, if I change [msWeekDay2] to use ROUND(#SpacingX#), the drift is only exaggerated.

Any idea why this is happening? I know I can probably fix it by changing how the regular meters get their X, but I'd like to solve it on this end, if possible.

I don't know if this is related to your problem, but I suggest switching to:

Code: Select all

[msWeekDay2]
Measure=Calc
Formula=#FirstX#+msWeekDay*#SpacingX#

Doesn't change anything, but that does simplify things. Thanks. (Post updated.)

I made another small change, and fixed the problem.

Code: Select all

;-----------------------
; INDICATOR

;Made this smaller using a simple formula
[msWeek]
Measure=CALC
Formula=#FirstY#+(CEIL((mDay+cMonthStart-1)/7)-1)*#SpacingY#

[msWeekDay]
Measure=TIME
Format=%#w

[msWeekDay2]
Measure=CALC
Formula=#FirstX#+msWeekDay*FLOOR(#SpacingX#)

EDIT:
SpacingX=(FLOOR((#SidebarWidth#-#FirstX#-19)/6))
This is probably a better idea, and works for me. Round, Ceil are just fine too.

Aha, Floor did the trick. Rainmeter must simply drop the remainder whenever it's told to use a non-integer for a meter position.

Thanks again, smurfier. :)
