Suddenly a blue line in array-border

[OnlyOne]

Hello,

i suddenly have a blue line on the left border of my first-array-cell.

Does this mean something? I have four identical array and see the line at two arrays, the third is without the blue-line.

Thanks

did you tried closing your VI and open again? to see if that blue line will disappear?

Yes, close/open does not help.

When copying the array it also copies the blue line.

Only if i create a new array it is without blue line. (But then i would have to replace all properties,references...)

That looks like the selection. I never used this option in arrays, so I don't really know how it functions. I believe you can hide it if you right click and go to the advanced menu (it might be somewhere else).

Hi,

tst is right. You have to right click on your array, go to "Advanced" and uncheck "Show Selection".

[shamelessly hijacking the thread, as I can't find any other relevant resource] But is it possible to control "Show selection" and the blue color programmatically, e.g. with property nodes? I found none relevant.

Neither have I, which probably means it was never added to the VI server API. It does appear as if it is part of the basic object flags property, but that property is private (for good reason) and you can only write to it when the VI is idle. I wouldn't be surprised that even if you would use it to change this, there would be some unexpected behaviors.

I later found this, which essentially says: "only with the paintbrush in the classic widget, not in the modern". As a workaround for toggling the display programmatically, I found that I can set e.g Selection Start=[-1] and Selection Size=[1]. For anything more complex, I indeed use tricks of clusters and transparent backgrounds like those reported, but they can become cumbersome to maintain.
