Virtual listicon color [Resolved]
Posted: Tue Oct 10, 2017 8:15 pm
Hello at all 
Thanks to RASHAD and NETMAESTRO, i have now a fast virtual listicon, able to give the XY and text value of the cell clicked
http://www.purebasic.fr/english/viewtop ... 96#p494696
But i want have the text of first column in blue
I have use SetItemColor but obviously that not works because it's a virtual ListIcon and she is managed only by the CallBack with the #Notify message
Worst... when i use SetItemColor, i believe the Subclassing of NETMAESTRO is called, and it's a nice whorehouse
Have you a way for changing the background, or text color of the code above ?
Have a good day

Have a good day
), who mean "your code is perhaps called, and that make a very bad behavior, mega flickering" normal because your code (i suppose) do his job and see the change of color and do something, see by the callback, and that turn around 
Thank's a lot MASTER for your french sentence
