-.SH DESCRIPTION
-The QListBox widget provides a list of selectable, read-only items.
-.PP
-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.
-.PP
-QListBox will add scroll bars as necessary, but it isn't intended for \fIreally\fR 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.)
-.PP
-There are a variety of selection modes described in the QListBox::SelectionMode documentation. The default is 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.)
-.PP
-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().
-.PP
-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.
-.PP
-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().
-.PP
-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.
-.PP
-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.
-.PP
-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).
-.PP
-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.
-.PP
-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.
-.PP
-If the user does not select anything, no signals are emitted and currentItem() returns -1.
-.PP
-A list box has WheelFocus as a default focusPolicy(), i.e. it can get keyboard focus by tabbing, clicking and through the use of the mouse wheel.
-.PP
-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().
-.PP
-By default, vertical and horizontal scroll bars are added and removed as necessary. setHScrollBarMode() and setVScrollBarMode() can be used to change this policy.
-.PP
-If you need to insert types other than strings and pixmaps, you must define new classes which inherit QListBoxItem.
-.PP
-\fBWarning:\fR The list box assumes ownership of all list box items and will delete them when it does not need them any more.

-.SS "Member Type Documentation"
-.SH "QListBox::LayoutMode"
-This enum type is used to specify how QListBox lays out its rows and columns.
-.TP
-\fCQListBox::FixedNumber\fR - There is a fixed number of rows (or columns).
-.TP
-\fCQListBox::FitToWidth\fR - There are as many columns as will fit on-screen.
-.TP
-\fCQListBox::FitToHeight\fR - There are as many rows as will fit on-screen.
-.TP
-\fCQListBox::Variable\fR - There are as many rows as are required by the column mode. (Or as many columns as required by the row mode.)
-.PP
-Example: When you call setRowMode( FitToHeight ), columnMode() automatically becomes Variable to accommodate the row mode you've set.
-.SH "QListBox::SelectionMode"
-This enumerated type is used by QListBox to indicate how it reacts to selection by the user.
-.TP
-\fCQListBox::Single\fR - 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().
-.TP
-\fCQListBox::Multi\fR - 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.
-.TP
-\fCQListBox::Extended\fR - 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.
-.TP
-\fCQListBox::NoSelection\fR - Items cannot be selected.
-.PP
-In other words, Single is a real single-selection list box, Multi is a real multi-selection list box, 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 NoSelection is for a list box where the user can look but not touch.
-.SH MEMBER FUNCTION DOCUMENTATION
-.SH "QListBox::QListBox ( QWidget * parent = 0, const char * name = 0, WFlags f = 0 )"
-Constructs a new empty list box called \fIname\fR and with parent \fIparent\fR.
-.PP
-Performance is boosted by modifying the widget flags \fIf\fR so that only part of the QListBoxItem children is redrawn. This may be unsuitable for custom QListBoxItem classes, in which case WStaticContents and WNoAutoErase should be cleared immediately after construction.
-.PP
-See also QWidget::clearWFlags() and Qt::WidgetFlags.
