Custom Column Icon Help

alanHd · 02-03-2013, 05:02 PM

Hi,

I have a custom column which is configured for long text like comments. I use this column to keep track of what i have done with that book, mainly Read of Reading.

I am trying to put a custom icons in this column to replace the text. eg an open book for reading and a closed book for Read.

The problem i am having is that when i set the icon to match the word read it also picks up on the word Reading. Is there any way to restrict it to just Read and not the word Reading.

You should use the "pattern" match with a regular expression. Although it isn't possible to say what regexp to use without knowing all the possible text structures in the column, the general approach is to use a pattern that matches only "read". Perhaps you could match "read" at the end of the string (read$), or "read" not followed by an i (read[^i]), or use two contains conditions to check read and not reading.

Thanks (read[^i]) worked great.
