NAME

       wxSplitterWindow - Functions for wxSplitterWindow class

DESCRIPTION

       This  class  manages  up  to  two  subwindows.  The  current  view  can  be split into two
       programmatically (perhaps from a menu command), and unsplit either programmatically or via
       the wxSplitterWindow user interface.

       Styles

       This class supports the following styles:

       See: wxSplitterEvent, Overview splitterwindow

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

       wxWidgets docs: wxSplitterWindow

EVENTS

       Event    types    emitted    from    this    class:    command_splitter_sash_pos_changing,
       command_splitter_sash_pos_changed, command_splitter_unsplit

DATA TYPES

       wxSplitterWindow() = wx:wx_object()

EXPORTS

       new() -> wxSplitterWindow()

              Default constructor.

       new(Parent) -> wxSplitterWindow()

              Types:

                 Parent = wxWindow:wxWindow()

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

              Types:

                 Parent = wxWindow:wxWindow()
                 Option =
                     {id, integer()} |
                     {pos, {X :: integer(), Y :: integer()}} |
                     {size, {W :: integer(), H :: integer()}} |
                     {style, integer()}

              Constructor for creating the window.

              Remark: After using this constructor, you must create either one or two  subwindows
              with   the   splitter  window  as  parent,  and  then  call  one  of  initialize/2,
              splitVertically/4 and splitHorizontally/4 in order to  set  the  pane(s).  You  can
              create  two  windows,  with  one hidden when not being shown; or you can create and
              delete the second pane on demand.

              See: initialize/2, splitVertically/4, splitHorizontally/4, create/3

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

              Destroys the wxSplitterWindow and its children.

       create(This, Parent) -> boolean()

              Types:

                 This = wxSplitterWindow()
                 Parent = wxWindow:wxWindow()

       create(This, Parent, Options :: [Option]) -> boolean()

              Types:

                 This = wxSplitterWindow()
                 Parent = wxWindow:wxWindow()
                 Option =
                     {id, integer()} |
                     {pos, {X :: integer(), Y :: integer()}} |
                     {size, {W :: integer(), H :: integer()}} |
                     {style, integer()}

              Creation function, for two-step construction.

              See new/2 for details.

       getMinimumPaneSize(This) -> integer()

              Types:

                 This = wxSplitterWindow()

              Returns the current minimum pane size (defaults to zero).

              See: setMinimumPaneSize/2

       getSashGravity(This) -> number()

              Types:

                 This = wxSplitterWindow()

              Returns the current sash gravity.

              See: setSashGravity/2

       getSashPosition(This) -> integer()

              Types:

                 This = wxSplitterWindow()

              Returns the current sash position.

              See: setSashPosition/3

       getSplitMode(This) -> wx:wx_enum()

              Types:

                 This = wxSplitterWindow()

              Gets the split mode.

              See: setSplitMode/2, splitVertically/4, splitHorizontally/4

       getWindow1(This) -> wxWindow:wxWindow()

              Types:

                 This = wxSplitterWindow()

              Returns the left/top or only pane.

       getWindow2(This) -> wxWindow:wxWindow()

              Types:

                 This = wxSplitterWindow()

              Returns the right/bottom pane.

       initialize(This, Window) -> ok

              Types:

                 This = wxSplitterWindow()
                 Window = wxWindow:wxWindow()

              Initializes the splitter window to have one pane.

              The child window is shown if it is currently hidden.

              Remark: This should be called if you wish to initially view only a single  pane  in
              the splitter window.

              See: splitVertically/4, splitHorizontally/4

       isSplit(This) -> boolean()

              Types:

                 This = wxSplitterWindow()

              Returns true if the window is split, false otherwise.

       replaceWindow(This, WinOld, WinNew) -> boolean()

              Types:

                 This = wxSplitterWindow()
                 WinOld = WinNew = wxWindow:wxWindow()

              This  function  replaces  one  of  the windows managed by the wxSplitterWindow with
              another one.

              It is in general better to use it instead of calling unsplit/2 and then resplitting
              the  window back because it will provoke much less flicker (if any). It is valid to
              call this function whether the splitter has two windows or only one.

              Both parameters should be non-NULL and winOld  must  specify  one  of  the  windows
              managed  by the splitter. If the parameters are incorrect or the window couldn't be
              replaced, false is returned. Otherwise the function will return  true,  but  please
              notice  that  it  will  not  delete  the  replaced window and you may wish to do it
              yourself.

              See: getMinimumPaneSize/1

       setSashGravity(This, Gravity) -> ok

              Types:

                 This = wxSplitterWindow()
                 Gravity = number()

              Sets the sash gravity.

              Remark: Gravity is real factor which  controls  position  of  sash  while  resizing
              wxSplitterWindow. Gravity tells wxSplitterWindow how much will left/top window grow
              while resizing. Example values:

              Notice that when sash gravity for a newly created  splitter  window,  it  is  often
              necessary  to  explicitly  set the splitter size using wxWindow:setSize/6 to ensure
              that is big enough for its initial sash position. Otherwise, i.e. if the window  is
              created  with the default tiny size and only resized to its correct size later, the
              initial sash position will be affected by the gravity and typically result in  sash
              being at the rightmost position for the gravity of 1. See the example code creating
              wxSplitterWindow in the splitter sample for more details.

              See: getSashGravity/1

       setSashPosition(This, Position) -> ok

              Types:

                 This = wxSplitterWindow()
                 Position = integer()

       setSashPosition(This, Position, Options :: [Option]) -> ok

              Types:

                 This = wxSplitterWindow()
                 Position = integer()
                 Option = {redraw, boolean()}

              Sets the sash position.

              Remark: Does not currently check for an out-of-range value.

              See: getSashPosition/1

       setMinimumPaneSize(This, PaneSize) -> ok

              Types:

                 This = wxSplitterWindow()
                 PaneSize = integer()

              Sets the minimum pane size.

              Remark: The default minimum pane size is zero, which means that either pane can  be
              reduced  to  zero  by dragging the sash, thus removing one of the panes. To prevent
              this behaviour (and veto out-of-range sash  dragging),  set  a  minimum  size,  for
              example  20 pixels. If the wxSP_PERMIT_UNSPLIT style is used when a splitter window
              is created, the window may be unsplit even if minimum size is non-zero.

              See: getMinimumPaneSize/1

       setSplitMode(This, Mode) -> ok

              Types:

                 This = wxSplitterWindow()
                 Mode = integer()

              Sets the split mode.

              Remark: Only sets the internal variable; does not update the display.

              See: getSplitMode/1, splitVertically/4, splitHorizontally/4

       splitHorizontally(This, Window1, Window2) -> boolean()

              Types:

                 This = wxSplitterWindow()
                 Window1 = Window2 = wxWindow:wxWindow()

       splitHorizontally(This, Window1, Window2, Options :: [Option]) ->
                            boolean()

              Types:

                 This = wxSplitterWindow()
                 Window1 = Window2 = wxWindow:wxWindow()
                 Option = {sashPosition, integer()}

              Initializes the top and bottom panes of the splitter window.

              The child windows are shown if they are currently hidden.

              Return: true if successful, false otherwise (the window was already split).

              Remark: This should be called if you wish to initially view two panes. It can  also
              be  called at any subsequent time, but the application should check that the window
              is not currently split using isSplit/1.

              See: splitVertically/4, isSplit/1, unsplit/2

       splitVertically(This, Window1, Window2) -> boolean()

              Types:

                 This = wxSplitterWindow()
                 Window1 = Window2 = wxWindow:wxWindow()

       splitVertically(This, Window1, Window2, Options :: [Option]) ->
                          boolean()

              Types:

                 This = wxSplitterWindow()
                 Window1 = Window2 = wxWindow:wxWindow()
                 Option = {sashPosition, integer()}

              Initializes the left and right panes of the splitter window.

              The child windows are shown if they are currently hidden.

              Return: true if successful, false otherwise (the window was already split).

              Remark: This should be called if you wish to initially view two panes. It can  also
              be  called at any subsequent time, but the application should check that the window
              is not currently split using isSplit/1.

              See: splitHorizontally/4, isSplit/1, unsplit/2

       unsplit(This) -> boolean()

              Types:

                 This = wxSplitterWindow()

       unsplit(This, Options :: [Option]) -> boolean()

              Types:

                 This = wxSplitterWindow()
                 Option = {toRemove, wxWindow:wxWindow()}

              Unsplits the window.

              Return: true if successful, false otherwise (the window was not split).

              Remark: This call will not  actually  delete  the  pane  being  removed;  it  calls
              OnUnsplit()  (not  implemented  in  wx)  which  can  be  overridden for the desired
              behaviour. By default, the pane being removed is hidden.

              See:   splitHorizontally/4,   splitVertically/4,   isSplit/1,   OnUnsplit()    (not
              implemented in wx)

       updateSize(This) -> ok

              Types:

                 This = wxSplitterWindow()

              Causes any pending sizing of the sash and child panes to take place immediately.

              Such  resizing normally takes place in idle time, in order to wait for layout to be
              completed. However, this can cause unacceptable flicker as the  panes  are  resized
              after the window has been shown. To work around this, you can perform window layout
              (for example by sending a size event to the parent  window),  and  then  call  this
              function, before showing the top-level window.
