QRegExp?

[Marco812]

Hi,

how can i set a range (0.24 – 2.06) to a QLineEdit with a QRegExp?

I try this

QRegExp regExpRange("(?:[0-2]24)(?:[.,]\\d\\d?)?|2(?:[.,]06?)?"); //Range 0.25 – 2.05
	myQLineEdit->setValidator(new QRegExpValidator(regExpRange, this));

QRegExp regExpRange("(?:[0-2]24)(?:[.,]\\d\\d?)?|2(?:[.,]06?)?"); //Range 0.25 – 2.05
	myQLineEdit->setValidator(new QRegExpValidator(regExpRange, this));

To copy to clipboard, switch view to plain text mode 

Thanks in advance

Try:

"0[.,]2[4-9]|0[.,][3-9]\\d|1[.,]\\d\\d|2.0[0-6]"

"0[.,]2[4-9]|0[.,][3-9]\\d|1[.,]\\d\\d|2.0[0-6]"

To copy to clipboard, switch view to plain text mode 

but maybe QDoubleSpinBox will be more usefull? There is also QDoubleValidator.

Hi,

thank you for the tip, but i think in this case is better to use QRegExp as a QDoubleValidator. Your QRegExp is OK, thank you.

Hi,

sorry i have found an error. I can put values like "2100" or "23" or "24".... I think that's OK:

"0[.,]2[4-9]|0[.,][3-9]\\d|1[.,]\\d\\d|2[.,]0[0-6]"

"0[.,]2[4-9]|0[.,][3-9]\\d|1[.,]\\d\\d|2[.,]0[0-6]"

To copy to clipboard, switch view to plain text mode
