I’ll make a small demo tomorrow if the problem isn’t resolved by then. I don’t have a lot of time atm 
And I’d also like to add that this problem does not occur on the corona simulator. It does though, on my galaxy s7 edge and the bluestacks emulator.
Hi guys,
So I found the first error in my code. I didn’t reference to the correct path, it should have been “img/sheetPickerWheel4.png”… But that didn’t solve my headache. I’m now presented with a complete white pickerWheel. Here is the code:
---// CREATING PICKERWHEER \\--- -- Loop through amount of days in a month for d=1, 31 do pickerWheel.days[d] = d end -- Loop through set number of years for y=1, 100 do pickerWheel.years[y] = 2012 + y end -- Implement column data pickerWheel.columnData = { -- Days { align = "center", width = 60, startIndex = 2, labels = pickerWheel.days }, -- Months { align = "center", width = 150, startIndex = 2, labels = { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" } }, -- Years { align = "center", width = 80, startIndex = 4, labels = pickerWheel.years } } local options = { frames = { { x=0, y=0, width=320, height=222 }, { x=320, y=0, width=320, height=222 }, { x=640, y=0, width=8, height=222 } }, sheetContentWidth = 648, sheetContentHeight = 222 } local pickerWheelSheet = graphics.newImageSheet( "img/sheetPickerWheel4.png", options ) pickerWheel.dateWidget = widget.newPickerWheel { top = display.contentHeight - 222, columns = pickerWheel.columnData, --overlayFrameWidth = actualW, sheet = pickerWheelSheet, overlayFrame = 1, overlayFrameWidth = 320, overlayFrameHeight = 222, backgroundFrame = 2, backgroundFrameWidth = 320, backgroundFrameHeight = 222, separatorFrame = 3, separatorFrameWidth = 8, separatorFrameHeight = 222, columnColor = { 1,1,1 }, fontColor = { 0.4, 0.4, 0.4, 0.5 }, fontColorSelected = { 0.2, 0.6, 0.4 } } pickerWheel.input = pickerWheel.dateWidget:getValues() pickerWheel.input.day = pickerWheel.input[1].value pickerWheel.yValueWidget = pickerWheel.dateWidget.y pickerWheel.heightValueWidget = pickerWheel.dateWidget.height

Isn’t there a way to just make a transparent pickerwheel so I can place a white rect behind it? Or to just make a full width and white pickerwheel?
Okay, yet another update. I managed to get the look I wanted (completely white, except the text). I feel like I’m finally getting somewhere 
I did this by using a spreadsheet with the same width and height, but this time the three frames are completely transparent!
But now I got one last problem. The pickerwheel is not in the center of my x-axis and not full width. Any way to resolve this issue?
Hi @bramvbilsen,
To clarify what was going on previously: basically, internally for some visual pieces, the pickerwheel takes certain image sheet frames and “stretches” them to fit the defined width. In this case, OpenGL is liable to borrow pixels from frames outside of that frame (neighboring frames) and actually apply them in a fade-in manner to the edges of the frame you’re using.
There are some slightly more advanced ways to prevent this, but the most simple solution in your case – assuming you want a purely white picker – is to just take a smaller “sample” of the first frame that doesn’t use the edge-to-edge dimensions. So, you could keep your actual image sheet exactly as it was before, but in your image sheet setup, you could do this:
[lua]
frames =
{
{ x=50, y=50, width=220, height=122 },
[/lua]
You’ll see how that basically takes a “piece” of the entire first frame, inset by 50 pixels on all sides, so that OpenGL won’t borrow any pixels from any outlying frames when it applies the stretched pieces during the internal construction of the widget.
Hope this makes sense,
Brent
P.S. - As for making the picker the entire width of the screen, that’s currently not possible, but we’re hoping to implement it soon (it has been a request in the queue for awhile and we know that it would be useful to developers).
Thanks Brent,
That totally worked out! I’ve made the pickerwheel “full width” by adding a white background to the widget so it looks like the widget and background are one piece. So… It’s not really full width but it gets the job done.
Once again, thanks for all your replies. You’ve been an enormous help for my project!
