Create open multiselect dialog to only directories
-
I found this code:
@
QFileDialog* _f_dlg = new QFileDialog(this);
_f_dlg->setFileMode(QFileDialog::DirectoryOnly);
_f_dlg->setOption(QFileDialog::DontUseNativeDialog, true);QListView *l = _f_dlg->findChild<QListView*>("listView"); if (l) { l->setSelectionMode(QAbstractItemView::MultiSelection); } QTreeView *t = _f_dlg->findChild<QTreeView*>(); if (t) { t->setSelectionMode(QAbstractItemView::MultiSelection); } int nMode = _f_dlg->exec(); QStringList _fnames = _f_dlg->selectedFiles();
@
But, this code return the path of current directory. For example: in "C:", I go inside of "images" and inside I choose 3 directories (folder1, folder2, folder3). But the result is a vector of strings of 4 elements:
-
C:\images
-
C:\images\folder1
-
C:\images\folder2
-
C:\images\folder3
I don't understand because. I want to remove that element (the path)

Ouch, modifying the dialog like that. That's ugly and will break when they decide to change eg. "listview" to "someList".
I would strongly suggest to implement your own dialog for that using eg. "QFileSystemModel":http://qt-project.org/doc/qt-5/qfilesystemmodel.htmlIf not then as you're "doing it wrong" already you might just as well modify the returned list the way you wanted:
@
_fnames.removeFirst();
std::for_each(_fnames.begin(), _fnames.end(), [](QString& s){ s = QDir(s).dirName(); });
