Why your code sub { selectAccount(+$i) } works?
And why my code sub { &selectAccount(+$i) } did not?
I took that code from a working script. I have always been using with the ampersand with binds.

When to use with & and when not to use?


Secondly, Am I doing it correctly: Tagging and Binding each line in that ROText?

My goal is to bind Button-1 to a highlight a line. and to bind Double-1 to change color/font of the line.


I have tried using Pane + Labels, Canvas but want to see alternatives and compare which is faster/efficient. Pane+Labels has the best quality, but suck in performance with long lists. Canvas still in the works. But ROText was my first iteration and it was fastest but suck in quality.


My next goal is to have a multiple column ListView with same ability to highlight a single line and change font/color. Again, Pane+Label's performance was terrible though appearance great.
