This can be text, a number or an item from a list. Also a label has to be set to tell the user what he/she should input. In this Qt version only the 4 static convenience functions getText(), getInteger(), getDouble() and getItem() of QInputDialog are available. Use it like this: \code bool ok = FALSE; QString text = QInputDialog::getText( tr( "Make an input" ), tr( "Please enter your name" ), QString::null, &ok, this ); if ( ok && !text.isEmpty() ) ;// user entered something and pressed ok else ;// user entered nothing or pressed cancel \endcode There are more static convenience methods! \sa getText(), getInteger(), getDouble(), getItem() */ /*! \enum QInputDialog::Type This enum type specifies the type of the dialog (which kind of input can be done): <ul> <li>\c LineEdit - A QLineEdit is used for taking the input, so a textual or (e.g. using a QValidator) a numerical input can be done. Using lineEdit() the QLineEdit can be accessed. <li>\c SpinBox - A QSpinBox is used for taking the input, so a decimal input can be done. Using spinBox() the QSpinBox can be accessed. <li>\c ComboBox - A read-only QComboBox is used for taking the input, so one item of a list can be chosen. Using comboBox() the QComboBox can be accessed. <li>\c EditableComboBox - An editable QComboBox is used for taking the input, so either one item of a list can be chosen or a text can be entered. Using editableComboBox() the QComboBox can be accessed. </ul> */ /*!
