Thanks, it's exactly that I wanted. Problem is solve.

@newbieQTDev said in Use a QDialog box in Win32 Application: This is the version of my QT. No this is the Qt version which was used to build QtCreator (which is a Qt app). You're using Qt 5.6.0

@SGaist Ahh thank you. Totally overlooked that while implementing.

I think that your question is not specifique enough What you can do is to derive from QWidget (creating a new class) In this class compose a QTimer object: http://doc.qt.io/qt-5/qtimer.html Then your widget is a empty box that have the functionality of a QTimer.... If you required that the QWidget has only one shot per click (guessing), you would like to use the static function SingleShot http://doc.qt.io/qt-5/qtimer.html#singleShot Kind Regards, Carlos

@Onikouzou What is this checkbox used for? If you only want to use a combobox then do: QInputDialog showSounds; QStringList soundList; soundList << "Sound 1" << "Sound 2"; showSounds.setOptions(QInputDialog::UseListViewForComboBoxItems); // Remove this if you want a combobox instead of a list showSounds.setComboBoxItems(soundList); showSounds.setWindowTitle("Select sounds"); showSounds.exec();

@Rohith no it's not. You would have to implement your custom QDialog subclass. Which shouldn't be much of an effort.
