NAME

       wxListBox - Functions for wxListBox class

DESCRIPTION

       A listbox is used to select one or more of a list of strings.

       The  strings  are  displayed  in  a  scrolling  box, with the selected string(s) marked in
       reverse video. A listbox can be single selection (if an item  is  selected,  the  previous
       selection  is  removed) or multiple selection (clicking an item toggles the item on or off
       independently of other selections).

       List box elements are numbered from zero and while  the  maximal  number  of  elements  is
       unlimited,  it  is  usually  better to use a virtual control, not requiring to add all the
       items to it at once, such as wxDataViewCtrl (not implemented in  wx)  or  wxListCtrl  with
       wxLC_VIRTUAL  style, once more than a few hundreds items need to be displayed because this
       control is not optimized, neither from performance nor from user interface point of  view,
       for large number of items.

       Notice that the list box doesn't support control characters other than TAB.

       Styles

       This class supports the following styles:

       See:   wxEditableListBox  (not  implemented  in  wx),  wxChoice,  wxComboBox,  wxListCtrl,
       wxCommandEvent

       This class is derived (and can use functions) from: wxControlWithItems wxControl  wxWindow
       wxEvtHandler

DATA TYPES

       wxListBox() = wx:wx_object()

EXPORTS

       new() -> wxListBox()

              Default constructor.

       new(Parent, Id) -> wxListBox()

              Types:

                 Parent = wxWindow:wxWindow()
                 Id = integer()

       new(Parent, Id, Options :: [Option]) -> wxListBox()

              Types:

                 Parent = wxWindow:wxWindow()
                 Id = integer()
                 Option =
                     {pos, {X :: integer(), Y :: integer()}} |
                     {size, {W :: integer(), H :: integer()}} |
                     {choices, [unicode:chardata()]} |
                     {style, integer()} |
                     {validator, wx:wx_object()}

              Constructor, creating and showing a list box.

              See the other new/3 constructor; the only difference is that this overload takes  a
              wxArrayString  (not implemented in wx) instead of a pointer to an array of wxString
              (not implemented in wx).

       destroy(This :: wxListBox()) -> ok

              Destructor, destroying the list box.

       create(This, Parent, Id, Pos, Size, Choices) -> boolean()

              Types:

                 This = wxListBox()
                 Parent = wxWindow:wxWindow()
                 Id = integer()
                 Pos = {X :: integer(), Y :: integer()}
                 Size = {W :: integer(), H :: integer()}
                 Choices = [unicode:chardata()]

       create(This, Parent, Id, Pos, Size, Choices, Options :: [Option]) ->
                 boolean()

              Types:

                 This = wxListBox()
                 Parent = wxWindow:wxWindow()
                 Id = integer()
                 Pos = {X :: integer(), Y :: integer()}
                 Size = {W :: integer(), H :: integer()}
                 Choices = [unicode:chardata()]
                 Option = {style, integer()} | {validator, wx:wx_object()}

       deselect(This, N) -> ok

              Types:

                 This = wxListBox()
                 N = integer()

              Deselects an item in the list box.

              Remark: This applies to multiple selection listboxes only.

       getSelections(This) -> Result

              Types:

                 Result = {Res :: integer(), Selections :: [integer()]}
                 This = wxListBox()

              Fill an array of ints with the positions of the currently selected items.

              Return: The number of selections.

              Remark: Use this with a multiple selection listbox.

              See:  wxControlWithItems:getSelection/1,   wxControlWithItems:getStringSelection/1,
              wxControlWithItems:setSelection/2

       insertItems(This, Items, Pos) -> ok

              Types:

                 This = wxListBox()
                 Items = [unicode:chardata()]
                 Pos = integer()

              Insert the given number of strings before the specified position.

       isSelected(This, N) -> boolean()

              Types:

                 This = wxListBox()
                 N = integer()

              Determines whether an item is selected.

              Return: true if the given item is selected, false otherwise.

       set(This, Items) -> ok

              Types:

                 This = wxListBox()
                 Items = [unicode:chardata()]

              Replaces the current control contents with the given items.

              Notice  that  calling this method is usually much faster than appending them one by
              one if you need to add a lot of items.

       hitTest(This, Point) -> integer()

              Types:

                 This = wxListBox()
                 Point = {X :: integer(), Y :: integer()}

              Returns the item located at point, or wxNOT_FOUND if there is no  item  located  at
              point.

              It is currently implemented for wxMSW, wxMac and wxGTK2 ports.

              Return: Item located at point, or wxNOT_FOUND if unimplemented or the item does not
              exist.

              Since: 2.7.0

       hitTest(This, X, Y) -> integer()

              Types:

                 This = wxListBox()
                 X = Y = integer()

              This is an overloaded member function, provided for convenience.  It  differs  from
              the above function only in what argument(s) it accepts.

       setFirstItem(This, N) -> ok

       setFirstItem(This, String) -> ok

              Types:

                 This = wxListBox()
                 String = unicode:chardata()

              Set the specified item to be the first visible item.
