Closing a QDialog

[eu.x]

Hi,

I create a widget based on a QDialog and I need to close it when a button inside this widget is pressed. I tried to connect signal/slot on the class constructor, but it doesn't works:



LoginUI::LoginUI(QWidget *parent) : QDialog(parent)
{
...

btnOK = new QPushButton("OK");
layDialog->addWidget(btnOK);

setLayout(layDialog);
setWindowTitle("Login");
setFixedHeight(180);
setFixedWidth(200);

QObject::connect(btnOK, SIGNAL(clicked()), this, SLOT(quit()));
}


In my main.cpp I call this widget using obj->exec();

Someone know how to close this dialog and continue the application?

Change the slot from quit() to close(). QDialog doesn't have "quit()".

You can use close, but the standard way of closing a dialog called with exec() is to use the slots accept() or reject(). This means that exec() returns a bool (true if accept, false if reject); you can use if( dialog->exec() ) to decide whether to apply whatever changes the user made in the dialog.
