Customize QFileDialog

[Swankee]

I have my FileDialog here:

QFileDialog box;
    QStringList fileNames;
 
    box.setFileMode(QFileDialog::ExistingFile);
    if (box.exec())
        {
           fileNames = box.selectedFiles();
        }

QFileDialog box;
    QStringList fileNames;
    
    box.setFileMode(QFileDialog::ExistingFile);
    if (box.exec())
        {
           fileNames = box.selectedFiles();
        }

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!

QFileSystemModel and QTableView or QTreeView.

QFileSystemModel and QTableView or QTreeView.

Cool, thank you!

Here's what I came up with, but why does it launch so slow (~10 seconds) when I try to display all drives ("\\"). It's as fast as you would expect when you only choose "C:\\"

QSplitter *splitter = new QSplitter;
    QDirModel *model = new QDirModel;
    model->setFilter( QDir::AllEntries | QDir::NoDotAndDotDot ) ;
    QTreeView *tree = new QTreeView(splitter);
    tree->setModel(model);
 
    tree->setRootIndex(model->index( "\\" ));
 
    splitter->setWindowTitle("Quick Look");
    splitter->show();

QSplitter *splitter = new QSplitter;
    QDirModel *model = new QDirModel;
    model->setFilter( QDir::AllEntries | QDir::NoDotAndDotDot ) ;
    QTreeView *tree = new QTreeView(splitter);
    tree->setModel(model);

    tree->setRootIndex(model->index( "\\" ));

    splitter->setWindowTitle("Quick Look");
    splitter->show();

Can anyone lend a hand?

thanks!

Because QDirModel is slow. Contrary to QFileSystemModel.

[Swankee]

Good to know.

Would you mind assisting with a piece of code?

[wysota]

Try and see.

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?

QFileSystemModel *model = new QFileSystemModel(this);
    model->setResolveSymlinks(true);
    QModelIndex root = model->setRootPath(QDir::rootPath());
    this->setVisible(model);

QFileSystemModel *model = new QFileSystemModel(this);
    model->setResolveSymlinks(true);
    QModelIndex root = model->setRootPath(QDir::rootPath());
    this->setVisible(model);

this->setVisible(model);

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?

[Swankee]

this->setVisible(model);

this->setVisible(model);

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

Here it is:

QFileSystemModel *model = new QFileSystemModel;
model->setRootPath("");
QTreeView *tree = new QTreeView();
tree->setModel(model);
 
QString title("Quick Look");
tree->setWindowTitle(title);
 
tree->show();

QFileSystemModel *model = new QFileSystemModel;
model->setRootPath("");
QTreeView *tree = new QTreeView();
tree->setModel(model);

QString title("Quick Look");
tree->setWindowTitle(title);

tree->show();

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