    \title Dynamic Layouts Example
    \brief Shows how to re-orient widgets in running applications.

    \e{Dynamic Layouts} implements dynamically placed widgets within running
    applications. The widget placement depends on whether \c Horizontal or \c
    Vertical is chosen.

    \section1 Dialog Constructor

    To begin with, the application creates the UI components by calling the
    following methods:

    \list
    \li createRotatableGroupBox()
    \li createOptionsGroupBox()
    \li createButtonBox()
    \endlist

    It then adds the UI components to a GridLayout (\c mainLayout).

    Finally, \c Dialog::rotateWidgets() is called.

    \quotefromfile layouts/dynamiclayouts/dialog.cpp
    \skipuntil createRotatableGroupBox
    \printuntil setWindowTitle

    \section1 Creating the Main Widgets

    The \c createRotatableGroupBox() method creates a rotatable group box,
    then adds a series of widgets:

    \list
    \li QSpinBox
    \li QSlider
    \li QDial
    \li QProgressBar
    \endlist

    It goes on to add signals and slots to each widget, and assigns
    a QGridLayout called \a rotatableLayout.

    \skipto Dialog::createRotatableGroupBox
    \printuntil /^\}/

    \section1 Adding Options

    \c createOptionsGroupBox() creates the following widgets:
    \list
    \li \c optionsGroupBox
    \li \c buttonsOrientationLabel
    \li \c buttonsOrientationComboBox. The orientation of the ComboBox is either
           \c horizontal (default value) or \c vertical. These two values
           are added during the startup of the application. It is not possible
           to leave the option empty.
    \endlist

    \skipto Dialog::createOptionsGroupBox()
    \printuntil /^\}/

    \section1 Adding Buttons

    createButtonBox() constructs a QDialogButtonBox called \c buttonBox
    to which are added a \c closeButton, a \c helpButton and a
    \c rotateWidgetsButton.
    It then assigns a signal and a slot to each button in \c buttonBox.

    \skipto Dialog::createButtonBox()
    \printuntil /^\}/


    \section1 Rotating the Widgets

    Removes the current widgets and activates the next widget.

    \quotefromfile layouts/dynamiclayouts/dialog.cpp
    \skipto Dialog::rotateWidgets()
    \printuntil rotatableLayout->addWidget(rotatableWidgets[i]
    \printuntil }
    \printuntil }

    \include examples-run.qdocinc
