wxSplitterWindow Class Reference

#include <wx/splitter.h>

Inheritance diagram for wxSplitterWindow:

Detailed 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:

• wxSP_3D:
  Draws a 3D effect border and sash.
• wxSP_THIN_SASH:
  Draws a thin sash.
• wxSP_3DSASH:
  Draws a 3D effect sash (part of default style).
• wxSP_3DBORDER:
  Synonym for wxSP_BORDER.
• wxSP_BORDER:
  Draws a standard border.
• wxSP_NOBORDER:
  No border (default).
• wxSP_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.
• wxSP_PERMIT_UNSPLIT:
  Always allow to unsplit, even with the minimum pane size other than zero.
• wxSP_LIVE_UPDATE:
  Don't draw XOR line but resize the child windows immediately.

Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxSplitterEvent& event)

Event macros for events emitted by this class:

• EVT_SPLITTER_SASH_POS_CHANGING(id, func):
  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(id, func):
  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(id, func):
  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(id, func):
  The splitter has been just unsplit. Processes a wxEVT_SPLITTER_UNSPLIT event.
• EVT_SPLITTER_DCLICK(id, func):
  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.

Constructor & Destructor Documentation

wxSplitterWindow() [1/2]

wxSplitterWindow::wxSplitterWindow

(

)

Default constructor.

wxSplitterWindow() [2/2]

wxSplitterWindow::wxSplitterWindow	(	wxWindow *	parent,
		wxWindowID	id = wxID_ANY,
		const wxPoint &	pos = wxDefaultPosition,
		const wxSize &	size = wxDefaultSize,
		long	style = wxSP_3D,
		const wxString &	name = "splitterWindow"
	)

Constructor for creating the window.

Parameters

parent	The parent of the splitter window.
id	The window identifier.
pos	The window position.
size	The window size.
style	The window style. See wxSplitterWindow.
name	The window name.

Remarks

After using this constructor, you must create either one or two subwindows with the splitter window as parent, and then call one of 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.

See also

Initialize(), SplitVertically(), SplitHorizontally(), Create()

~wxSplitterWindow()

virtual wxSplitterWindow::~wxSplitterWindow ( )

virtual

Destroys the wxSplitterWindow and its children.

Member Function Documentation

Create()

bool wxSplitterWindow::Create	(	wxWindow *	parent,
		wxWindowID	id = wxID_ANY,
		const wxPoint &	point = wxDefaultPosition,
		const wxSize &	size = wxDefaultSize,
		long	style = wxSP_3D,
		const wxString &	name = "splitter"
	)

Creation function, for two-step construction.

See wxSplitterWindow() for details.

GetDefaultSashSize()

int wxSplitterWindow::GetDefaultSashSize

(

)

const

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.

Since

2.9.4

GetLastSplitPosition()

wxPoint wxSplitterWindow::GetLastSplitPosition

(

)

const

Get the last sash position before the splitter was unsplit.

The last sash position gets updated each time the window is unsplit. It is kept internally to allow restoring the sash in its previous position when if it is split again.

Returns

Point whose x/y component corresponds to the position of the vertical/horizontal sash before the last unsplit or 0 if the splitter was never split in the corresponding direction.

Since

3.3.0

GetMinimumPaneSize()

int wxSplitterWindow::GetMinimumPaneSize

(

)

const

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

See also

SetMinimumPaneSize()

GetSashGravity()

double wxSplitterWindow::GetSashGravity

(

)

const

Returns the current sash gravity.

See also

IsSashInvisible()

bool wxSplitterWindow::IsSashInvisible

(

)

const

Returns true if the sash is invisible even when the window is split, false otherwise.

Remarks

This is a shortcut for HasFlag(wxSP_NOSASH)

IsSplit()

bool wxSplitterWindow::IsSplit

(

)

const

Returns true if the window is split, false otherwise.

OnDoubleClickSash()

virtual void wxSplitterWindow::OnDoubleClickSash ( int  x, int  y  )

virtual

Application-overridable function called when the sash is double-clicked with the left mouse button.

Parameters

x	The x position of the mouse cursor.
y	The y position of the mouse cursor.

Remarks

The default implementation of this function calls Unsplit if the minimum pane size is zero.

See also

Unsplit()

OnSashPositionChange()

virtual bool wxSplitterWindow::OnSashPositionChange ( int  newSashPosition )

virtual

Application-overridable function called when the sash position is changed by user.

It may return false to prevent the change or true to allow it.

Parameters

newSashPosition

The new sash position (always positive or zero)

Remarks

The default implementation of this function verifies that the sizes of both panes of the splitter are greater than minimum pane size.

OnUnsplit()

virtual void wxSplitterWindow::OnUnsplit ( wxWindow *  removed )

virtual

Application-overridable function called when the window is unsplit, either programmatically or using the wxSplitterWindow user interface.

Parameters

removed

The window being removed.

Remarks

The default implementation of this function simply hides removed. You may wish to delete the window.

ReplaceWindow()

bool wxSplitterWindow::ReplaceWindow	(	wxWindow *	winOld,
		wxWindow *	winNew
	)

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() 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.

GetMinimumPaneSize()

SetLastSplitPosition()

void wxSplitterWindow::SetLastSplitPosition

(

const wxPoint &

pos

)

Sets the last sash position.

This does not affect the actual sash position while the window is split but determines the initial position of the sash when the window gets split in the future.

Parameters

pos	Point containing the default positions for wxSPLIT_VERTICAL and wxSPLIT_HORIZONTAL modes respectively in its x and y components.

Since

3.3.0

SetMinimumPaneSize()

void wxSplitterWindow::SetMinimumPaneSize

(

int

paneSize

)

Sets the minimum pane size.

Parameters

paneSize

Minimum pane size in pixels.

Remarks

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.

GetMinimumPaneSize()

SetSashGravity()

void wxSplitterWindow::SetSashGravity

(

double

gravity

)

Sets the sash gravity.

Parameters

gravity

The sash gravity. Value between 0.0 and 1.0.

Remarks

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:

• 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 wxSplitterWindow.

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 wxSplitterWindow in the splitter sample for more details.

GetSashGravity()

SetSashInvisible()

void wxSplitterWindow::SetSashInvisible

(

bool

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.

Remarks

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

Parameters

invisible

If true, the sash is always invisible, else it is shown when the window is split.

2.9.4

SetSashPosition()

void wxSplitterWindow::SetSashPosition	(	int	position,
		bool	redraw = true
	)

Sets the sash position.

Parameters

position	The sash position in pixels. Note that a position of 0 will set the sash to the middle of the window. A negative value will "wrap around" the sash's position. For example, -10 will place the sash at 10 units from right of the splitter window.
redraw	If true, resizes the panes and redraws the sash and border.

Remarks

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

GetSashPosition()

SetSplitMode()

void wxSplitterWindow::SetSplitMode

(

int

mode

)

Sets the split mode.

Parameters

mode	Can be wxSPLIT_VERTICAL or wxSPLIT_HORIZONTAL.

Remarks

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

See also

GetSplitMode(), SplitVertically(), SplitHorizontally().

SplitHorizontally()

virtual bool wxSplitterWindow::SplitHorizontally ( wxWindow *  window1, wxWindow *  window2, int  sashPosition = 0  )

virtual

Initializes the top and bottom panes of the splitter window.

The child windows are shown if they are currently hidden.

Parameters

window1	The top pane.
window2	The bottom pane.
sashPosition	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).

Returns

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

Remarks

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(), IsSplit(), Unsplit()

SplitVertically()

virtual bool wxSplitterWindow::SplitVertically ( wxWindow *  window1, wxWindow *  window2, int  sashPosition = 0  )

virtual

Initializes the left and right panes of the splitter window.

The child windows are shown if they are currently hidden.

Parameters

window1	The left pane.
window2	The right pane.
sashPosition	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).

Returns

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

Remarks

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()

bool wxSplitterWindow::Unsplit

(

wxWindow *

toRemove = nullptr

)

Unsplits the window.

Parameters

toRemove

The pane to remove, or nullptr to remove the right or bottom pane.

Returns

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

Remarks

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.

See also

SplitHorizontally(), SplitVertically(), IsSplit(), OnUnsplit()

UpdateSize()

void wxSplitterWindow::UpdateSize

(

)

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.
