When i am entering a value in Line Edit the decimal values should not exceed more than 3 decimals. How can i set the precision for this decimals values?
Example:

Try this way...
@QString::number( double n, char format = 'g', int precision = 3)@
-
Or, if you care about other nations, you can use this:
@
QLocale().toString( n, 'g', 3 )
