What's the benefit of FileSystemModel::getFileInfo()? I would guess your this pointer is a nullptr

@notsofast I'm facing the same problem, so can I ask if you solved it?

@mahesh_j said in File Browser with context menu to unzip files: But I don't know what actions to add to the QMenu The actions you need. You have to create such a pop-up menu. Take a look at http://quazip.sourceforge.net/

@jeremy_k Wow, Awesome ! Thanks for your answer and massive props to @VRonin !

Ok I found what was causing this awful bug. When I check if the map contains the index, I actually check the raw index not the QPersistantModelIndex so this is not the same object and I think qmap does not check equality using == operator . So I have to iterate over the map and check using QPersistantModelIndex "==" operators which can compare from a QModelIndex.

Hi, Apply the same filter you are using for your single folder version except that this time rather than using a QString you should keep a QStringList of the folders you want to show and use that.

That wasn't really clear from your original description. In that case, use a filter. QSortFilterProxyModel for example

I had issues making these solutions work for the QML TreeView. I ended up setting the root path of my QFileSystemModel to the directory I wanted to view. Then I set the rootIndex in the TreeView to the parent of the index for that directory. This is of course showed its siblings. Then I did the following to filter those siblings away. I also made this optional through a property as there are times when I want that behavior: bool filterAcceptsRow(int source_row, const QModelIndex &source_parent) const { FileSystemModel* tmodel = qobject_cast<FileSystemModel*>(parent()); if(tmodel){ QModelIndex index = tmodel->index(source_row, 0, source_parent); QModelIndex rootIndex = tmodel->index(tmodel->rootPath()); if(!rootIndex.isValid() || !index.isValid()) return false; return ((index == rootIndex) || !(tmodel->filtersiblings() && isSiblingOf(index, rootIndex))); } return false; } bool isSiblingOf(const QModelIndex& index, const QModelIndex& parent) const { if(!index.isValid() || !parent.isValid()) return false; QModelIndex sibling; int row=0; do{ sibling = parent.sibling(row,0); if(sibling == index) return true; ++row; }while(sibling.isValid()); return false; } I took more of a blacklist approach versus a whitelist approach.

@tokafr Super. so it can copy files on its own ? Doc hinted it, but I was not sure.

@tokafr Oh. That would have been too easy then :) http://stackoverflow.com/questions/11050977/removing-a-non-empty-folder-in-qt has a function that looks good. bool removeDir(const QString & dirName) make sure to give it full path. I dont think QFileSystemModel can do it directly . Not that i have seen.

That I understood. That's why I think that QDirIterator is a better tool to find what you want on your drive.

Thanks everybody

You're welcome ! By the way, now you can use the "Topic Tool" button to mark the thread as solved, it keeps the things cleaner :)

Brilliant thanks!

@Chris-Kawa I am building from within Qt Creator (Windows 7), my .pro file didn't contain that! it just had: QT += gui Thank you Chris.
