+  \brief A convenience dialog to get a simple input from the user
+  \ingroup dialogs
+
+  The QInputDialog is a simple dialog which can be used if you
+  need a simple input from the user. 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>
