/*!
    \class QListBox qlistbox.h
    \brief The QListBox widget provides a list of selectable, read-only items.

    \ingroup advanced
    \mainclass

    This is typically a single-column list in which either no item or
    one item is selected, but it can also be used in many other ways.

    QListBox will add scroll bars as necessary, but it isn't intended
    for \e really big lists. If you want more than a few thousand
    items, it's probably better to use a different widget mainly
    because the scroll bars won't provide very good navigation, but
    also because QListBox may become slow with huge lists. (See
    QListView and QTable for possible alternatives.)

    There are a variety of selection modes described in the
    QListBox::SelectionMode documentation. The default is \c Single
    selection mode, but you can change it using setSelectionMode().
    (setMultiSelection() is still provided for compatibility with Qt
    1.x. We recommend using setSelectionMode() in all code.)

    Because QListBox offers multiple selection it must display
    keyboard focus and selection state separately. Therefore there are
    functions both to set the selection state of an item, i.e.
    setSelected(), and to set which item displays keyboard focus, i.e.
    setCurrentItem().

    The list box normally arranges its items in a single column and
    adds a vertical scroll bar if required. It is possible to have a
    different fixed number of columns (setColumnMode()), or as many
    columns as will fit in the list box's assigned screen space
    (setColumnMode(FitToWidth)), or to have a fixed number of rows
    (setRowMode()) or as many rows as will fit in the list box's
    assigned screen space (setRowMode(FitToHeight)). In all these
    cases QListBox will add scroll bars, as appropriate, in at least
    one direction.

    If multiple rows are used, each row can be as high as necessary
    (the normal setting), or you can request that all items will have
    the same height by calling setVariableHeight(FALSE). The same
    applies to a column's width, see setVariableWidth().

    The QListBox's items are QListBoxItem objects. QListBox provides
    methods to insert new items as strings, as pixmaps, and as
    QListBoxItem * (insertItem() with various arguments), and to
    replace an existing item with a new string, pixmap or QListBoxItem
    (changeItem() with various arguments). You can also remove items
    singly with removeItem() or clear() the entire list box. Note that
    if you create a QListBoxItem yourself and insert it, QListBox
    takes ownership of the item.

    You can also create a QListBoxItem, such as QListBoxText or
    QListBoxPixmap, with the list box as first parameter. The item
    will then append itself. When you delete an item it is
    automatically removed from the list box.

    The list of items can be arbitrarily large; QListBox will add
    scroll bars if necessary. QListBox can display a single-column
    (the common case) or multiple-columns, and offers both single and
    multiple selection. QListBox does not support multiple-column
    items (but QListView and QTable do), or tree hierarchies (but
    QListView does).

    The list box items can be accessed both as QListBoxItem objects
    (recommended) and using integer indexes (the original QListBox
    implementation used an array of strings internally, and the API
    still supports this mode of operation). Everything can be done
    using the new objects, and most things can be done using indexes.

    Each item in a QListBox contains a QListBoxItem. One of the items
    can be the current item. The currentChanged() signal and the
    highlighted() signal are emitted when a new item becomes current,
    e.g. because the user clicks on it or QListBox::setCurrentItem()
    is called. The selected() signal is emitted when the user
    double-clicks on an item or presses Enter on the current item.

    If the user does not select anything, no signals are emitted and
    currentItem() returns -1.

    A list box has \c WheelFocus as a default focusPolicy(), i.e. it
    can get keyboard focus by tabbing, clicking and through the use of
    the mouse wheel.

    New items can be inserted using insertItem(), insertStrList() or
    insertStringList(). inSort() is obsolete because this method is
    quite inefficient. It's preferable to insert the items normally
    and call sort() afterwards, or to insert a sorted QStringList().

    By default, vertical and horizontal scroll bars are added and
    removed as necessary. setHScrollBarMode() and setVScrollBarMode()
    can be used to change this policy.

    If you need to insert types other than strings and pixmaps, you
    must define new classes which inherit QListBoxItem.

    \warning The list box assumes ownership of all list box items and
    will delete them when it does not need them any more.

/*!
    \enum QListBox::SelectionMode

    This enumerated type is used by QListBox to indicate how it reacts
    to selection by the user.

    \value Single  When the user selects an item, any already-selected
    item becomes unselected and the user cannot unselect the selected
    item. This means that the user can never clear the selection, even
    though the selection may be cleared by the application programmer
    using QListBox::clearSelection().

    \value Multi  When the user selects an item the selection status
    of that item is toggled and the other items are left alone. Also,
    multiple items can be selected by dragging the mouse while the
    left mouse button is kept pressed.

    \value Extended When the user selects an item the selection is
    cleared and the new item selected. However, if the user presses
    the Ctrl key when clicking on an item, the clicked item gets
    toggled and all other items are left untouched. And if the user
    presses the Shift key while clicking on an item, all items between
    the current item and the clicked item get selected or unselected,
    depending on the state of the clicked item. Also, multiple items
    can be selected by dragging the mouse while the left mouse button
    is kept pressed.

    \value NoSelection  Items cannot be selected.

    In other words, \c Single is a real single-selection list box, \c
    Multi is a real multi-selection list box, \c Extended is a list
    box in which users can select multiple items but usually want to
    select either just one or a range of contiguous items, and \c
    NoSelection is for a list box where the user can look but not
    touch.

    on-screen.

    \value FitToHeight  There are as many rows as will fit on-screen.

    \value Variable  There are as many rows as are required by the
    column mode. (Or as many columns as required by the row mode.)

    Example: When you call setRowMode( FitToHeight ), columnMode()
    automatically becomes \c Variable to accommodate the row mode
    you've set.
