Methods

static void explore(
    const std::string& path,
    const unsigned long mask,
    TFileInfoList& outList
    )

The path of the directory to examine must be passed to this constructor, among the According to the following parameters, the object will collect the list of files, which can be modified later through other methods in this class.

Parameters:

path

The path to examine (IT MUST BE A DIRECTORY), e.g “d:temp", or “/usr/include/”

One or the OR’ed combination of the values “FILE_ATTRIB_ARCHIVE” and “FILE_ATTRIB_DIRECTORY”, depending on what file types do you want in the list (These values are platform-independent).

outList

The list of found files/directories is stored here.

See also:

sortByName

static void sortByName(TFileInfoList& lstFiles, bool ascendingOrder = true)

Sort the file entries by name, in ascending or descending order.

static void filterByExtension(TFileInfoList& lstFiles, const std::string& extension)

Remove from the list of files those whose extension does not coincide (without case) with the given one.

Example: filterByExtension(lst,”txt”);
