Error at setFile to a QFileInfoList with a QString

Lets assume I have:

QList<QString> filenameList;

filenameList has the paths to some files.

Then I create a QFileInfoList

QFileInfoList fileInfoList;

How can I use .setFile method for every object in the fileInfoList? I tried:

for(int i=0;i<filenameList.length();i++)
 {

    fileInfoList[i].setFile(filenameList[i]);
 }

But I get this error after trying the program(it compiles succesfully).

ASSERT failure in QList<T>::at: "index out of range"

Can someone help me?

Solution

  • fileInfoList is empty when you try to access the first element of the list. What you want to do is replace the call to setFile with

    fileInfoList.append(QFileInfo(filenameList[i]));
