Qt: add a file selection field on the form (QLineEdit and "browse" button)
Should I implement it by hand? Or, what is the correct way to do this?
Yes, I agree with you that it is a common thing, but unfortunately you will need to implement this yourself. The good news is that you can do this easily by something like this:
MyMainWindow::createUI()
{
label = new QLabel("foo");
button = new QPushButton("Browse");
connect(button, SIGNAL(clicked()), SLOT(browse()));
layout = new QHorizontalLayout();
layout->addWidget(label);
layout->addWidget(button);
setLayout(layout);
}
void MyMainWindow::browse()
{
QString directory = QFileDialog::getExistingDirectory(this,
tr("Find Files"), QDir::currentPath());
if (!directory.isEmpty()) {
if (directoryComboBox->findText(directory) == -1)
directoryComboBox->addItem(directory);
directoryComboBox->setCurrentIndex(directoryComboBox->findText(directory));
}
}

I need to display
QLineEdit
with "Browse" button at my form. When user clicks button,QFileDialog
should be opened, and so on.This is pretty common thing, but I can't find ready-made solution for that. I expected in Qt Designer some widget like
QFileSelect
, or something like that, but found nothing similar.Should I implement it by hand? Or, what is the correct way to do this?
