I am having a qt question. I want the QLineEdit widget to have the focus at application startup. Take the following code for example: #include <QtGui/QApplication> #include <QtGui/QHBoxLayout> #include <QtGui/QPushButton> #include <QtGui/QLineEdit> #include <QtGui/QFont> int main(int argc, char *argv[]) { QApplication app(argc, argv); QWidget *window = new QWidget(); window->setWindowIcon(QIcon("qtest16.ico")); window->setWindowTitle("QtTest"); QHBoxLayout *layout = new QHBoxLayout(window); // Add some widgets. QLineEdit *line = new QLineEdit(); QPushButton *hello = new QPushButton(window); hello->setText("Select all"); hello->resize(150, 25); hello->setFont(QFont("Droid Sans Mono", 12, QFont::Normal)); // Add the widgets to the layout. layout->addWidget(line); layout->addWidget(hello); line->setFocus(); QObject::connect(hello, SIGNAL(clicked()), line, SLOT(selectAll())); QObject::connect(line, SIGNAL(returnPressed()), line, SLOT(selectAll())); window->show(); return app.exec(); } Why does line->setFocus() sets the focus on the line widget @app startup only if it is placed after laying out the widgets and if used before it's not working?
