Solution

I am trying to increase the scrollbar width of the array with customization for a touchscreen application. The changes in scrollbar width are not retained when closing LabVIEW and opening it again. I tried making it strict typedef and still, the changes are not retained. I also tried with other types of controls like modern and classic. I have attached the previews for reference.

Anyone have any ideas how this can be done? 

Thanks!!

It appears to be a LabVIEW bug.  I can't think of an easy solution; a hard solution would be to create an XControl.

It doesn't work with making it a Custom Control? If so, I guess you'll have to drop a free scrollbar from the numeric panel and use that ones events to change your array.

Yes I too was frustrated by standard width scrollbars on touch screens and tried a few things.  Here is a XControl I made which has the ability set it to a larger width and can fit to a pane.  Open the Demo Large Scroll to see it in action.

Got a solution here

Adding following keys in LV ini file enables resizing scrollbars.

AutosizeScrollbar=False

autoResizeScrollbars=false

I never tested those INI keys but I thought that those didn't work consistently.  They would work on your system but when the EXE is built and put on a computer without those INI keys it would revert back, or other developers opening the VIs would see the normal scrollbars, save the VI and then when it was reopened it wouldn't retain the size.

I guess your installer needs to change the LV.ini then. 😉
