But it is showing an error.

@Shubham-Gupta
~~you'll have to read up on the Conditional Operator~~

~~It reqiuers 2 expression after the ? your examply only has 1~~

forget everything, it's to damn early in the morning.

What?
I din get your words.

dheerendra

Please paste your code here. You need to use ternary operator. You may be doing in some mistake. Hence requested paste the code.

@dheerendra

validator: val===0?DoubleValidator{
                top: top_value
                bottom:bottom_value}
             : RegExpValidator{regExp: ""}

I am trying to make regular exp for accepting time(mm:ss).
But its showing an error.

dheerendra

Hi dheerendra
In qml there are three validators

IntValidator
DoubleValidator
RegExpValidator

If i want to store text like 2:30 (mm:ss). So which validator will work.
If RegExpValidor is used, so what will be the regular expression for this syntax (mm:ss).

dheerendra

Use RegExpValidator. Did you check the google for regular expression for mm:ss ? It should help.

Good. Move the case to "Solved" state. It helps others as well.
