    Default Customize QFileDialog

    I have my FileDialog here:
    Qt Code:
    1. QStringList fileNames;
    2.  
    3. box.setFileMode(QFileDialog::ExistingFile);
    4. if (box.exec())
    5. {
    6. fileNames = box.selectedFiles();
    7. }
    To copy to clipboard, switch view to plain text mode 

    It works on a button click just fine. Am I able to streamline what it looks like? I'm not interested in having the user open or choose files but rather just view that files are present. Really what would be perfect would be a windows explorer type window where I could view files / not only the directories. Is there anything out there for what I've described? thanks!

    Qt Code:
    1. QSplitter *splitter = new QSplitter;
    2. QDirModel *model = new QDirModel;
    3. model->setFilter( QDir::AllEntries | QDir::NoDotAndDotDot ) ;
    4. QTreeView *tree = new QTreeView(splitter);
    5. tree->setModel(model);
    6.  
    7. tree->setRootIndex(model->index( "\\" ));
    8.  
    9. splitter->setWindowTitle("Quick Look");
    10. splitter->show();
    To copy to clipboard, switch view to plain text mode

    Can anyone lend a hand?

    thanks!

    Because QDirModel is slow. Contrary to QFileSystemModel.

    Here's what I was able to come up with but it's not displaying on click. It compiles but it doesnt' work. Could you help me get it to display?

    Qt Code:
    1. QFileSystemModel *model = new QFileSystemModel(this);
    2. model->setResolveSymlinks(true);
    3. QModelIndex root = model->setRootPath(QDir::rootPath());
    4. this->setVisible(model);
    To copy to clipboard, switch view to plain text mode

    This doesn't make much sense. What do you expect it to do?

    I ended up getting it working. I thought that would set the model visible, no?

    Here it is:
    Qt Code:
    1. QFileSystemModel *model = new QFileSystemModel;
    2. model->setRootPath("");
    3. QTreeView *tree = new QTreeView();
    4. tree->setModel(model);
    5.  
    6. QString title("Quick Look");
    7. tree->setWindowTitle(title);
    8.  
    9. tree->show();
    To copy to clipboard, switch view to plain text mode

    Model is just a concept, it can't be made "visible".
