Hi.
Hopefully this will be useful to someone else.
Want to use a Panel.Grid with repeating BarV or BarH shapes but find that the bars appear too soon ? So you want gap | shape | gap but you get shape | gap | shape ?
Use gridOrigin to offset the count that trips the bars appearance. It takes a go.Point parameter so can offset for both horizontal and vertical axes. Use a -ve offset equal to the width of your bar if you want gap | shape | gap.
Might be worth Northwoods considering adding something to the intro grid patterns section
