    Default Euro sign

    Hello anyone,

    Iám using qt-4.4.0 on windows Xp

    I have a model with several columns.
    In the second column i have value's like this € 20.000
    € 70.000
    € 500.000
    € 750.000 etc ...

    I want to sum the euro numbers and put the sum into LineEdit.

    I have read some documentation but i can't find something about this.
    The value € 20.000 have 3 different things.
    The first one is € i think this is a string.
    The second is whitespace between the euro sign en the number.
    The third is the dot in the number.
    Normally i can make sum with integers.(not with strings);
    I have tried severall ListIterators but nothing works.
    Must i first remove the € and the whitespace and the dot and then sum the numbers?

    Have somebody experencie with this.

    Thanks in advance.

    May you can try regular expression to get the 75.00 part, and convert it to int or double using QString::toInt() or QString::toDouble() methods.

    If you have control over the model, I suggest to define another role and adjust the data() function to return the pure double number (as a QVariant) for that role. Saves you the bother of parsing formatted output.
