Unsolved access a file in the root path directory using QFileSystem hierarchy
-
Hi,
I'm currently using the QFileSystemModel class and i just can't get the point of the row and column hierarchy. I got that the rows number defines the number of children. But what about the columns? What does it represent? I'm currently trying to set a new root path to the n°x child of a directory using its index but i just can't find this file using the row and column hierarchy that i naturally think of in the index(int row, int column, QModelIndex *parent) method which for me should be index(x,0 or 1 depending on 0-based or not, current root path file's index).I already thank you for your help.

I haven't used
QFileSystemHierarchy
, and I don't fully understand what your issues are, so I could be out on this... :)I think it has columns as well as rows partly because it's derived from
QAbstractItemModel
. I imagine the columns are a file's attributes (name, size, date, ...)(?) I think you should ignore columns.QModelIndex
is the key thing.- Just use functions like
QString filePath(const QModelIndex &index) const
to get values from an item at an index - and functions like
QModelIndex index(const QString &path, int column = 0) const
andQModelIndex setRootPath(const QString &newPath)
to generate an index from a path. Note that these do not need a column, only a path.
P.S.

Use
children()
(from base class,QAbstractItemModel
) to access and iterate a directory's child files/directories. Nothing to do with row/column. - Just use functions like
