--- Comment #3 from Shawn Rutledge <s@ecloud.org> ---
Here is the problem:

bool KDEPlatformFileDialogHelper::show(Qt::WindowFlags windowFlags,
Qt::WindowModality windowModality, QWindow *parent)
{
    initializeDialog();
    m_dialog->setWindowFlags(windowFlags);
    m_dialog->setModal(windowModality != Qt::NonModal);
    if (windowModality == Qt::NonModal) {
        m_dialog->show();
...

The QtQuick FileDialog is window modal by default.  That is not a reason to
avoid showing it.  Unlike widget-based applications, QtQuick applications
cannot call QDialog::exec().  So the modality is just meant to request the
window manager to make the window behave as a modal one.

So I tried taking out the "if".  That makes it work OK with QtQuick.  Then I
tried qtbase/examples/widgets/dialogs/standarddialogs.  If I call any of the
static methods (e.g. getOpenFileName()), the dialog appears but is
non-interactive, so I can't actually choose a file.

We don't have this problem with plain QFileDialog or with any other native
dialogs on other platforms, so I'm confident that it can be fixed.
