Nested QDialog automatically presses a QPushButton inside of it - c++

Question

#include <QApplication>
#include <QDebug>
#include <QDialog>
#include <QPushButton>
#include <QTreeWidget>
#include <QVBoxLayout>
int main(int argc, char** argv)
{
QApplication app(argc, argv);
QDialog dialog;
QVBoxLayout layout(&dialog);
QTreeWidget treeWidget;
treeWidget.insertTopLevelItem(0, new QTreeWidgetItem(&treeWidget));
QObject::connect(&treeWidget, &QTreeWidget::activated, [&treeWidget]() {
auto secondDialog = new QDialog(&treeWidget);
auto layout = new QVBoxLayout(secondDialog);
auto button = new QPushButton();
QObject::connect(button, &QPushButton::clicked, []() {
qDebug() << "button clicked";
});
layout->addWidget(button);
secondDialog->show();
});
layout.addWidget(&treeWidget);
dialog.show();
return app.exec();
}
When I activate a QTreeWidget's item by pressing Enter, nested dialog is created and it immediately presses button inside of it. How do I get rid of it?

Answer 1

I solved this by overriding keyPressEvent of the QTreeView that was inside the dialog:
class EnterEatingTreeView : public BaseTreeView
{
public:
explicit EnterEatingTreeView(QWidget* parent = nullptr)
: BaseTreeView(parent)
{
}
protected:
void keyPressEvent(QKeyEvent* event) override
{
BaseTreeView::keyPressEvent(event);
switch (event->key()) {
case Qt::Key_Enter:
case Qt::Key_Return:
event->accept();
}
}
};
This way pressing Enter key inside QTreeView doesn't passes to its parent.
