wx.SplitterWindow¶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 wx.SplitterWindow user interface.
^^
Window Styles¶This class supports the following styles:
wx.SP_3D: Draws a 3D effect border and sash.
wx.SP_THIN_SASH: Draws a thin sash.
wx.SP_3DSASH: Draws a 3D effect sash (part of default style).
wx.SP_3DBORDER: Synonym for wx.SP_BORDER.
wx.SP_BORDER: Draws a standard border.
wx.SP_NOBORDER: No border (default).
wx.SP_NO_XP_THEME: Under Windows, switches off the attempt to draw the splitter using Windows theming, so the borders and sash will take on the pre-XP look.
wx.SP_PERMIT_UNSPLIT: Always allow to unsplit, even with the minimum pane size other than zero.
wx.SP_LIVE_UPDATE: Don’t draw wx.XOR line but resize the child windows immediately. ^^
^^
Events Emitted by this Class¶Handlers bound for the following event types will receive a wx.SplitterEvent parameter.
EVT_SPLITTER_SASH_POS_CHANGING: The sash position is in the process of being changed. May be used to modify the position of the tracking bar to properly reflect the position that would be set if the drag were to be completed at this point. Processes a wxEVT_SPLITTER_SASH_POS_CHANGING event.
EVT_SPLITTER_SASH_POS_RESIZE: The sash position is in the process of being updated. May be used to modify the position of the tracking bar to properly reflect the position that would be set if the update were to be completed. This can happen e.g. when the window is resized and the sash is moved according to the gravity setting. This event is sent when the window is resized and allows the application to select the desired new sash position. If it doesn’t process the event, the position is determined by the gravity setting. Processes a wxEVT_SPLITTER_SASH_POS_RESIZE event and is only available in wxWidgets 3.1.6 or newer.
EVT_SPLITTER_SASH_POS_CHANGED: The sash position was changed. May be used to modify the sash position before it is set, or to prevent the change from taking place. Processes a wxEVT_SPLITTER_SASH_POS_CHANGED event.
EVT_SPLITTER_UNSPLIT: The splitter has been just unsplit. Processes a wxEVT_SPLITTER_UNSPLIT event.
EVT_SPLITTER_DCLICK: The sash was double clicked. The default behaviour is to unsplit the window when this happens (unless the minimum pane size has been set to a value greater than zero). Processes a wxEVT_SPLITTER_DOUBLECLICKED event. ^^

Inheritance diagram for class SplitterWindow:
wx.SplitterWindow(Window)¶Possible constructors:
SplitterWindow()
SplitterWindow(parent, id=ID_ANY, pos=DefaultPosition, size=DefaultSize,
style=SP_3D, name="splitterWindow")
This class manages up to two subwindows.
__init__(self, *args, **kw)¶
Overloaded Implementations:
__init__ (self)
Default constructor.
__init__ (self, parent, id=ID_ANY, pos=DefaultPosition, size=DefaultSize, style=SP_3D, name=”splitterWindow”)
Constructor for creating the window.
parent (wx.Window) – The parent of the splitter window.
id (wx.WindowID) – The window identifier.
pos (wx.Point) – The window position.
size (wx.Size) – The window size.
style (long) – The window style. See wx.SplitterWindow.
name (string) – The window name.
Note
After using this constructor, you must create either one or two subwindows with the splitter window as parent, and then call one of wx.Initialize , SplitVertically and SplitHorizontally 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.

Create(self, parent, id=ID_ANY, point=DefaultPosition, size=DefaultSize, style=SP_3D, name="splitter")¶Creation function, for two-step construction.
See wx.SplitterWindow for details.
GetClassDefaultAttributes(variant=WINDOW_VARIANT_NORMAL)¶variant (WindowVariant) –
GetDefaultSashSize(self)¶Returns the default sash size in pixels.
The size of the sash is its width for a vertically split window and its height for a horizontally split one. Its other direction is the same as the client size of the window in the corresponding direction.
The default sash size is platform-dependent because it conforms to the current platform look-and-feel and cannot be changed.
int
New in version 2.9.4.
GetMinimumPaneSize(self)¶Returns the current minimum pane size (defaults to zero).
int
See also
GetSashGravity(self)¶Returns the current sash gravity.
float
See also
GetSashPosition(self)¶Returns the current sash position.
int
See also
GetSashSize(self)¶Returns the default sash size in pixels or 0 if it is invisible.
int
See also
GetSplitMode(self)¶Gets the split mode.
See also
Initialize(self, window)¶Initializes the splitter window to have one pane.
The child window is shown if it is currently hidden.
window (wx.Window) – The pane for the unsplit window.
Note
This should be called if you wish to initially view only a single pane in the splitter window.
See also
IsSashInvisible(self)¶Returns True if the sash is invisible even when the window is split, False otherwise.
bool
New in version 2.9.4.
Note
This is a shortcut for HasFlag(wxSP_NOSASH)
See also
IsSplit(self)¶Returns True if the window is split, False otherwise.
bool
ReplaceWindow(self, winOld, winNew)¶This function replaces one of the windows managed by the wx.SplitterWindow with another one.
It is in general better to use it instead of calling Unsplit 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 not None 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 also
SetMinimumPaneSize(self, paneSize)¶Sets the minimum pane size.
paneSize (int) – Minimum pane size in pixels.
Note
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 wx.SP_PERMIT_UNSPLIT style is used when a splitter window is created, the window may be unsplit even if minimum size is non-zero.
See also
SetSashGravity(self, gravity)¶Sets the sash gravity.
gravity (float) – The sash gravity. Value between 0.0 and 1.0.
Notice that when sash gravity for a newly created splitter window, it is often necessary to explicitly set the splitter size using SetSize 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 wx.SplitterWindow in the splitter sample for more details.
Note
Gravity is real factor which controls position of sash while resizing wx.SplitterWindow. Gravity tells wx.SplitterWindow how much will left/top window grow while resizing. Example values:
0.0: only the bottom/right window is automatically resized
0.5: both windows grow by equal size
1.0: only left/top window grows Gravity should be a real value between 0.0 and 1.0. Default value of sash gravity is 0.0. That value is compatible with previous (before gravity was introduced) behaviour of wx.SplitterWindow.
See also
SetSashInvisible(self, invisible=True)¶Sets whether the sash should be invisible, even when the window is split.
When the sash is invisible, it doesn’t appear on the screen at all and, in particular, doesn’t allow the user to resize the windows.
invisible (bool) – If True, the sash is always invisible, else it is shown when the window is split.
New in version 2.9.4.
Note
Only sets the internal variable; does not update the display.
See also
SetSashPosition(self, position, redraw=True)¶Sets the sash position.
position (int) – The sash position in pixels.
redraw (bool) – If True, resizes the panes and redraws the sash and border.
Note
Does not currently check for an out-of-range value.
See also
SetSplitMode(self, mode)¶Sets the split mode.
mode (int) – Can be wx.SPLIT_VERTICAL or wx.SPLIT_HORIZONTAL.
Note
Only sets the internal variable; does not update the display.
See also
SplitHorizontally(self, window1, window2, sashPosition=0)¶Initializes the top and bottom panes of the splitter window.
The child windows are shown if they are currently hidden.
window1 (wx.Window) – The top pane.
window2 (wx.Window) – The bottom pane.
sashPosition (int) – The initial position of the sash. If this value is positive, it specifies the size of the upper pane. If it is negative, its absolute value gives the size of the lower pane. Finally, specify 0 (default) to choose the default position (half of the total window height).
bool
True if successful, False otherwise (the window was already split).
Note
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 .
See also
SplitVertically(self, window1, window2, sashPosition=0)¶Initializes the left and right panes of the splitter window.
The child windows are shown if they are currently hidden.
window1 (wx.Window) – The left pane.
window2 (wx.Window) – The right pane.
sashPosition (int) – The initial position of the sash. If this value is positive, it specifies the size of the left pane. If it is negative, it is absolute value gives the size of the right pane. Finally, specify 0 (default) to choose the default position (half of the total window width).
bool
True if successful, False otherwise (the window was already split).
Note
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 .
See also
SplitHorizontally , IsSplit , Unsplit .
Unsplit(self, toRemove=None)¶Unsplits the window.
toRemove (wx.Window) – The pane to remove, or None to remove the right or bottom pane.
bool
True if successful, False otherwise (the window was not split).
Note
This call will not actually delete the pane being removed; it calls OnUnsplit which can be overridden for the desired behaviour. By default, the pane being removed is hidden.

SplitHorizontally , SplitVertically , IsSplit , OnUnsplit
UpdateSize(self)¶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.
