Hi,
I have a table on webvisu with array of 100 BOOL.
When I click on cell of table, I change value true to false or false to true.
I want solution to fill fastly cell by click on first line of table and press hold ctrl (or over key), and next click on second line : if value on first cline is TRUE, put automatically TRUE until second line.
How to detect Ctrl key hold ?
Thank you for your help.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Ok, it work. I forget function VisuInit on visualisation manager.
But I want only detect Ctrl or Alt, and this programm detect all other but not this one...
