File sorting and selection

[foolah44]

Hi everyone.

I have recently started using Qt. I want to create a window containing a list of files in a pre selected folder.
Also, in that window, i want to include three radio button: by name, by type and by folder. Each of the radio button will have to sort the file list accordingly.

I understand this has to do with Qt Model/View. But I have so much trouble finding the appropriate model for this.
I dont really see how to sort the file list when a radio button is checked.

Thank you.

This is my code to populate the list so far:

void batchWindow::populateTable()
{

QDir directory(folderName);
fileList = directory.entryList();
QStringListModel *model = new QStringListModel(fileList);
elements->setModel(model);

}

But it only gives a list of the main folder, not sub folders.

You should design a function that gets folderName. The code you gave is only populating the table once, you have to re-populate it to show files and folders in a different directory.
Something that does the following when a file is selected from the list:

(a bit of pseudocode)

@
if (selection is a folder) {
return name of folder

} else {
// deal with opening file or else

}
@

and call your populateTable() again with a different folderName.
Personally, considered the case, I would add an argument to populateTable()

@populateTable(QString folderName)@

(is it supposed to be a QString or QDir?)

I think that is how you could do it, but you surely have to change the folderName to update the list.

QTDavid,

folderName is a private member of the class batchwindow
I didn't find necessary to add it as an argument to populateTable()

I have changed my model to QFileSystemModel and it works better now:

@
void batchWindow::populateTable()
{
QDir directory(folderName);
fileList = directory.entryList();

QFileSystemModel *model = new QFileSystemModel;
model->removeColumn(3);
elements->setModel(model);
model->setRootPath(folderName);
elements->setRootIndex(model->index(folderName));
elements->hideColumn(3);

}
@

I have also created a slot sortTable() that runs when a radio button is checked.

@
void batchWindow::sortTable()
{
QDir directory(folderName);
fileList = directory.entryList();

if (byFolder->isChecked()){

    QFileSystemModel *model = new QFileSystemModel;
    elements->setModel(model);
    model->setRootPath(folderName);
    elements->setRootIndex(model->index(folderName));
    elements->hideColumn(3);
}
if (byName->isChecked()){

}

}

It is a bit repetive but it works for the moment. I am now trying to figure out how to sort by name and by type.
