I need to display floating point values from 0.0 to 100 like

0.0, 0.1,0.2 ....

I am trying to use display(double) in QLCDNumber class...

But it will not make any effect .

What does "has no effect" mean in this case?
Can't you see no lcd number widget at all? Doesn't the number widget show a correct number? Have you changed the numDigits property?

QLCDNumber uses ints. You have to set an integer and use setSmallDecimalPoint() to set the decimal point. You can't use doubles directly.

Sorry, I don't mean like that ..


As u said , I try to change the numDigit property.

I can't chane the value at runtime by using the function display() in QLCDNumber class .
