Qt Designer enables us to display LCD-like digits of any size by making use of its LCD Number
widget. The LCD Number
widget is an instance of the QLCDNumber
class and it can be used to display decimal, hexadecimal, octal, and binary digits of any size. The methods provided by QLCDNumber
are as follows:
setMode()
: This method is used to change the base of the numbers. Available options are as follows:Hex
: This option is used to display hexadecimal digitsDec
: This option is used to display decimal digitsOct
: This option is used to display octal digitsBin
: This option is used to display binary digits
display()
: This method is used to display the supplied data in LCD digit format.value()
: This method returns the numerical value displayed by theLCD Number
widget.
We want the displayed system clock time to be updated automatically. For this, we need to implement timers.
