[SOLVED]Registering fields from a QTreeView embedded in a QWizardPage

cobaltsixty

Hi all,

I'm trying to build a wizard. As a very first step, I need a directory selection from user. I decided to use a QTreeView to make it happen. The problem for me is registering a field that contains user selection. I need help to understand how to this since I did not manage to use the registerField() function in such a context.

Here is the code I use:
@directoryPage::directoryPage(QWidget *parent) :
QWizardPage(parent)
{
setTitle(tr("Selecting a directory"));

QFileSystemModel *model = new QFileSystemModel();
model->setFilter(QDir::Dirs);
model->setRootPath(QDir::homePath());

treeView = new QTreeView();
treeView -> setModel(model);
treeView -> setRootIndex(model->index(QDir::homePath()));
treeView -> hideColumn(3);
treeView -> hideColumn(2);
treeView -> hideColumn(1);
treeView -> setSelectionMode(QAbstractItemView::SingleSelection);

QVBoxLayout *layout = new QVBoxLayout;
layout->addWidget(treeView);
setLayout(layout);

//registerField("inputDirectory", treeView, model->filePath(treeView->selectionModel()->selectedIndexes()));

}
@

Thanks a lot for your help :-)

Hi and welcome to devnet,

QTreeView doesn't have such a property to register with QWizardPage. However you could subclass QTreeView and add the property yourself.

Hope it helps

@SGaist, Thx. This could be a solution. I was just looking for something more straightforward. Will do if nothing else comes up. Cheers

If I need to implement you solution, my first guess would be:

creating a class inheriting from QTreeView --> myQtreeView
adding a QString *selectedDirectory as a property
creating a private hasChanged() slot that "stores" the data
connecting this slot to the currentChanged signal from QItemSelectionModel (the model being retrieved from QTreeView::selectionModel().

Sorry but I'm quite new to Qt. Do you think this is a correct strategy ?

Thanks again.

solved. Thanks.

Sorry I've lost track on this one. Nice you found out !

Just one thing, no need to allocate QString on the heap
