3 | wxWindow is the base class for all windows. Any children of the window will be deleted | |
4 | automatically by the destructor before the window itself is deleted. | |
5 | ||
6 | %Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this | |
7 | %help text. These must not be called by a user program and are documented only for illustration. | |
8 | %On several platforms, only a few of these handlers are actually written (they are not always | |
9 | %needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept | |
10 | %the respective event as usual and call \helpref{wxEvent::Skip}{wxeventskip} so that the native | |
11 | %platform can implement its native behaviour or just ignore the event if nothing needs to be | |
12 | %done. | |

25 | The following styles can apply to all windows, although they will not always make sense for a particular | |
26 | window class or on all platforms. | |

31 | for this style. } | |
32 | \twocolitem{\windowstyle{wxDOUBLE\_BORDER}}{Displays a double border. Windows only.} | |
33 | \twocolitem{\windowstyle{wxSUNKEN\_BORDER}}{Displays a sunken border.} | |
34 | \twocolitem{\windowstyle{wxRAISED\_BORDER}}{Displays a raised border. GTK only. } | |
35 | \twocolitem{\windowstyle{wxSTATIC\_BORDER}}{Displays a border suitable for a static control. Windows only. } | |
36 | \twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint | |
37 | events. Windows only.} | |
38 | \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.} | |
39 | \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that the window | |
40 | wants to get all char events - even for keys like TAB or ENTER which are | |
41 | usually used for dialog navigation and which wouldn't be generated without | |
42 | this style} | |
43 | \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{Disables repainting | |
44 | the window completely when its size is changed - you will have to repaint the | |
45 | new window area manually if you use this style. Currently only has an effect for | |
46 | Windows.} | |
47 | \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.} | |
48 | \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.} | |
49 | \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars, | |
50 | disable them instead of hiding them when they are not needed (i.e. when the | |
51 | size of the window is big enough to not require the scrollbars to navigate it). | |
52 | This style is currently only implemented for wxMSW and wxUniversal and does | |
53 | nothing on the other platforms.} | |
54 | \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being | |

62 | The following are extra styles, set using \helpref{wxWindow::SetExtraStyle}{wxwindowsetextrastyle}. | |

64 | \twocolwidtha{5cm}% | |
65 | \begin{twocollist}\itemsep=0pt | |
66 | \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{By default, Validate/TransferDataTo/FromWindow() | |
67 | only work on direct children of the window (compatible behaviour). Set this flag to make them recursively | |
68 | descend into all subwindows.} | |
69 | \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the | |
70 | parent window and so on recursively by default. Using this flag for the | |
71 | given window allows to block this propagation at this window, i.e. prevent | |
72 | the events from being propagated further upwards. Dialogs have this | |
73 | flag on by default.} | |
74 | \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must | |
75 | be used with transient windows as otherwise there is the risk of creating a | |
76 | dialog/frame with this window as a parent which would lead to a crash if the | |
77 | parent is destroyed before the child.} | |
78 | \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even | |
79 | if the mode set by \helpref{wxIdleEvent::SetMode}{wxidleeventsetmode} is wxIDLE\_PROCESS\_SPECIFIED.} | |
80 | \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_UI\_UPDATES}}{This window should always process UI update events, | |

91 | ||
92 | \func{}{wxWindow}{\void} | |
93 | ||
94 | Default constructor. | |
95 | ||
96 | \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id}, | |
97 | \param{const wxPoint\& }{pos = wxDefaultPosition}, | |
98 | \param{const wxSize\& }{size = wxDefaultSize}, | |
99 | \param{long }{style = 0}, | |
100 | \param{const wxString\& }{name = wxPanelNameStr}} | |
101 | ||
102 | Constructs a window, which can be a child of a frame, dialog or any other non-control window. | |
103 | ||
104 | \wxheading{Parameters} | |
105 | ||
106 | \docparam{parent}{Pointer to a parent window.} | |
107 | ||
108 | \docparam{id}{Window identifier. If -1, will automatically create an identifier.} | |
109 | ||
110 | \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows | |
111 | should generate a default position for the window. If using the wxWindow class directly, supply | |
112 | an actual position.} | |
113 | ||
114 | \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWindows | |
115 | should generate a default size for the window. If no suitable size can be found, the | |
116 | window will be sized to 20x20 pixels so that the window is visible but obviously not | |
117 | correctly sized. } | |
118 | ||
119 | \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.} | |
120 | ||

122 | ||
123 | \membersection{wxWindow::\destruct{wxWindow}} | |
124 | ||
125 | \func{}{\destruct{wxWindow}}{\void} | |
126 | ||
127 | Destructor. Deletes all subwindows, then deletes itself. Instead of using | |
128 | the {\bf delete} operator explicitly, you should normally | |
129 | use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows | |
130 | can delete a window only when it is safe to do so, in idle time. | |

137 | ||
138 | \membersection{wxWindow::AddChild} | |
139 | ||
140 | \func{virtual void}{AddChild}{\param{wxWindow* }{child}} | |
141 | ||
142 | Adds a child window. This is called automatically by window creation | |
143 | functions so should not be required by the application programmer. | |
144 | ||
145 | \wxheading{Parameters} | |
146 | ||
147 | \docparam{child}{Child window to add.} | |
148 | ||
149 | \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse} | |
150 | ||
151 | \func{virtual void}{CaptureMouse}{\void} | |
152 | ||
153 | Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to | |
154 | release the capture. | |
155 | ||
156 | Note that wxWindows maintains the stack of windows having captured the mouse | |
157 | and when the mouse is released the capture returns to the window which had had | |
158 | captured it previously and it is only really released if there were no previous | |
159 | window. In particular, this means that you must release the mouse as many times | |
160 | as you capture it. | |

179 | ||
180 | \func{void}{CenterOnScreen}{\param{int}{ direction}} | |
181 | ||
182 | A synonym for \helpref{CentreOnScreen}{wxwindowcentreonscreen}. | |
183 | ||
184 | \membersection{wxWindow::Centre}\label{wxwindowcentre} | |
185 | ||
186 | \func{void}{Centre}{\param{int}{ direction = wxBOTH}} | |
187 | ||
188 | Centres the window. | |
189 | ||
190 | \wxheading{Parameters} | |
191 | ||
192 | \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp | |
193 | or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag | |
194 | if you want to center the window on the entire screen and not on its | |
195 | parent window.} | |
196 | ||
197 | The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer | |
198 | (it has no effect). | |
199 | ||
200 | \wxheading{Remarks} | |
201 | ||
202 | If the window is a top level one (i.e. doesn't have a parent), it will be | |
203 | centered relative to the screen anyhow. | |

209 | \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent} | |
210 | ||
211 | \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}} | |
212 | ||
213 | Centres the window on its parent. This is a more readable synonym for | |
214 | \helpref{Centre}{wxwindowcentre}. | |
215 | ||
216 | \wxheading{Parameters} | |
217 | ||
218 | \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp | |
219 | or {\tt wxBOTH}.} | |
220 | ||
221 | \wxheading{Remarks} | |
222 | ||
223 | This methods provides for a way to center top level windows over their | |
224 | parents instead of the entire screen. If there is no parent or if the | |
225 | window is not a top level window, then behaviour is the same as | |
226 | \helpref{wxWindow::Centre}{wxwindowcentre}. | |
227 | ||

230 | \helpref{wxWindow::CentreOnScreen}{wxwindowcenteronscreen} | |

232 | \membersection{wxWindow::CentreOnScreen}\label{wxwindowcentreonscreen} | |
233 | ||
234 | \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}} | |
235 | ||
236 | Centres the window on screen. This only works for top level windows - | |
237 | otherwise, the window will still be centered on its parent. | |
238 | ||
239 | \wxheading{Parameters} | |
240 | ||
241 | \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp | |

248 | \membersection{wxWindow::ClearBackground}\label{wxwindowclearbackground} | |
249 | ||
250 | \func{void}{ClearBackground}{\void} | |
251 | ||
252 | Clears the window by filling it with the current background colour. Does not | |
253 | cause an erase background event to be generated. | |
254 | ||
255 | \membersection{wxWindow::ClientToScreen} | |
256 | ||
257 | \constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}} | |
258 | ||
259 | \perlnote{In wxPerl this method returns a 2-element list instead of | |
260 | modifying its parameters.} | |
261 | ||
262 | \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}} | |
263 | ||
264 | Converts to screen coordinates from coordinates relative to this window. | |
265 | ||
266 | \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and | |
267 | a screen coordinate will be passed out.} | |
268 | ||

270 | a screen coordinate will be passed out.} | |
271 | ||
272 | \docparam{pt}{The client position for the second form of the function.} | |
273 | ||
274 | \pythonnote{In place of a single overloaded method name, wxPython | |

282 | \membersection{wxWindow::Close}\label{wxwindowclose} | |
283 | ||
284 | \func{bool}{Close}{\param{bool}{ force = {\tt false}}} | |
285 | ||
286 | This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose | |
287 | handler usually tries to close the window. It doesn't close the window itself, | |
288 | however. | |
289 | ||
290 | \wxheading{Parameters} | |
291 | ||
292 | \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction | |
293 | of this window, {\tt true} if it cannot.} | |
294 | ||
295 | \wxheading{Remarks} | |
296 | ||
297 | Close calls the \helpref{close handler}{wxcloseevent} for the window, providing | |
298 | an opportunity for the window to choose whether to destroy the window. | |
299 | Usually it is only used with the top level windows (wxFrame and wxDialog | |
300 | classes) as the others are not supposed to have any special OnClose() logic. | |
301 | ||
302 | The close handler should check whether the window is being deleted forcibly, | |
303 | using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it | |
304 | should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}. | |
305 | ||
306 | {\it Note} that calling Close does not guarantee that the window will be | |
307 | destroyed; but it provides a way to simulate a manual close of a window, which | |
308 | may or may not be implemented by destroying the window. The default | |
309 | implementation of wxDialog::OnCloseWindow does not necessarily delete the | |
310 | dialog, since it will simply simulate an wxID\_CANCEL event which is handled by | |
311 | the appropriate button event handler and may do anything at all. | |
312 | ||
313 | To guarantee that the window will be destroyed, call | |
314 | \helpref{wxWindow::Destroy}{wxwindowdestroy} instead | |

324 | \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}} | |
325 | ||
326 | \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}} | |
327 | ||
328 | Converts a point or size from dialog units to pixels. | |
329 | ||
330 | For the x dimension, the dialog units are multiplied by the average character width | |
331 | and then divided by 4. | |
332 | ||
333 | For the y dimension, the dialog units are multiplied by the average character height | |
334 | and then divided by 8. | |
335 | ||
336 | \wxheading{Remarks} | |
337 | ||
338 | Dialog units are used for maintaining a dialog's proportions even if the font changes. | |
339 | Dialogs created using Dialog Editor optionally use dialog units. | |
340 | ||
341 | You can also use these functions programmatically. A convenience macro is defined: | |
342 | ||
343 | {\small | |
344 | \begin{verbatim} | |
345 | #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt) | |

406 | Destroys the window safely. Use this function instead of the delete operator, since | |
407 | different window classes can be destroyed differently. Frames and dialogs | |
408 | are not destroyed immediately when this function is called -- they are added | |
409 | to a list of windows to be deleted on idle time, when all the window's events | |
410 | have been processed. This prevents problems with events being sent to non-existent | |
411 | windows. | |
412 | ||
413 | \wxheading{Return value} | |

439 | Does the window-specific updating after processing the update event. | |
440 | This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui} | |
441 | in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and | |
442 | act appropriately. For example, to allow frame and dialog title updating, wxWindows | |
443 | implements this function as follows: | |
444 | ||

593 | of a window. Mainly useful with scrolled windows to reset scrollbars after | |
594 | sizing changes that do not trigger a size event, and/or scrolled windows without | |
595 | an interior sizer. This function similarly won't do anything if there are no | |
596 | subwindows. | |
597 | ||
598 | \membersection{wxWindow::Freeze}\label{wxwindowfreeze} | |
599 | ||
600 | \func{virtual void}{Freeze}{\void} | |
601 | ||
602 | Freezes the window or, in other words, prevents any updates from taking place | |
603 | on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must | |
604 | be called to reenable window redrawing. | |
605 | ||
606 | This method is useful for visual appearance optimization (for example, it | |
607 | is a good idea to use it before inserting large amount of text into a | |
608 | wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all | |

623 | ||
624 | This method is similar to \helpref{GetBestSize}{wxwindowgetbestsize}, except | |
625 | in one thing. GetBestSize should return the minimum untruncated size of the | |
626 | window, while this method will return the largest of BestSize and any user | |

646 | This functions returns the best acceptable minimal size for the window. For | |
647 | example, for a static control, it will be the minimal size such that the | |
648 | control label is not truncated. For windows containing subwindows (typically | |
649 | \helpref{wxPanel}{wxpanel}), the size returned by this function will be the | |
650 | same as the size the window would have had after calling | |

1825 | \wxheading{Remarks} | |
1826 | ||
1827 | An event handler is an object that is capable of processing the events | |
1828 | sent to a window. By default, the window is its own event handler, but | |
1829 | an application may wish to substitute another, for example to allow | |
1830 | central implementation of event-handling for a variety of different | |
1831 | window classes. | |
1832 | ||
1833 | \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows | |
1834 | an application to set up a chain of event handlers, where an event not handled by one event handler is | |
1835 | handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to | |
1836 | remove the event handler. | |

2110 | The background colour is usually painted by the default\rtfsp | |
2111 | \helpref{wxEraseEvent}{wxeraseevent} event handler function | |
2112 | under Windows and automatically under GTK. | |
2113 | ||
2114 | Note that setting the background colour does not cause an immediate refresh, so you | |

2117 | ||
2118 | Use this function with care under GTK+ as the new appearance of the window might | |

2142 | ||
2143 | This sets the size of the window client area in pixels. Using this function to size a window | |
2144 | tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not | |

2269 | events are propagated upwards to the window parent recursively until a handler | |

2281 | This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so | |

2417 | \wxheading{Remarks} | |
2418 | ||
2419 | Let's say you wish to display 50 lines of text, using the same font. | |
2420 | The window is sized so that you can only see 16 lines at a time. | |
2421 | ||
2422 | You would use: | |
2423 | ||
2424 | {\small% | |
2425 | \begin{verbatim} | |
2426 | SetScrollbar(wxVERTICAL, 0, 16, 50); | |
2427 | \end{verbatim} | |
2428 | } | |
2429 | ||
2430 | Note that with the window at this size, the thumb position can never go | |
2431 | above 50 minus 16, or 34. | |
2432 | ||
2433 | You can determine how many lines are currently visible by dividing the current view | |
2434 | size by the character height in pixels. | |
2435 | ||
2436 | When defining your own scrollbar behaviour, you will always need to recalculate | |
2437 | the scrollbar settings when the window size changes. You could therefore put your | |
2438 | scrollbar calculations and SetScrollbar | |
2439 | call into a function named AdjustScrollbars, which can be called initially and also | |
2440 | from your \helpref{wxSizeEvent}{wxsizeevent} handler function. | |

2455 | ||
2456 | \docparam{orientation}{Determines the scrollbar whose page size is to be set. May be wxHORIZONTAL or wxVERTICAL.} | |

2459 | ||
2460 | \docparam{refresh}{{\tt true} to redraw the scrollbar, {\tt false} otherwise.} | |
2461 | ||
2462 | \wxheading{Remarks} | |
2463 | ||
2464 | The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you | |
2465 | click on the area above/left of or below/right of the thumb. Normally you will want a whole visible | |
2466 | page to be scrolled, i.e. the size of the current view (perhaps the window client size). This | |
2467 | value has to be adjusted when the window is resized, since the page size will have changed. | |
2468 | ||
2469 | In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows | |
2470 | the thumb changes size to reflect the page size relative to the length of the document. When the | |
2471 | document size is only slightly bigger than the current view (window) size, almost all of the scrollbar | |
2472 | will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems) | |
2473 | disappear. | |
2474 | ||
2475 | Currently, this function should be called before SetPageRange, because of a quirk in the Windows | |
2476 | handling of pages and ranges. | |

2528 | ||
2529 | The range of a scrollbar is the number of steps that the thumb may travel, rather than the total | |
2530 | object length of the scrollbar. If you are implementing a scrolling window, for example, you | |
2531 | would adjust the scroll range when the window is resized, by subtracting the window view size from the | |
2532 | total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero | |
2533 | and usually the scrollbar will be automatically hidden. | |

2696 | \func{virtual void}{SetThemeEnabled}{\param{bool }{enable}} | |
2697 | ||
2698 | This function tells a window if it should use the system's "theme" code | |
2699 | to draw the windows' background instead if its own background drawing | |
2700 | code. This does not always have any effect since the underlying platform | |
2701 | obviously needs to support the notion of themes in user defined windows. | |
2702 | One such platform is GTK+ where windows can have (very colourful) backgrounds | |
2703 | defined by a user's selected theme. | |
2704 | ||
2705 | Dialogs, notebook pages and the status bar have this flag set to true | |
2706 | by default so that the default look and feel is simulated best. | |

2780 | ||
2781 | Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise} | |
2782 | for a top level window if you want to bring it to top, although this is not | |
2783 | needed if Show() is called immediately after the frame creation. | |

2861 | ||
2862 | \func{virtual void}{Update}{\void} | |
2863 | ||
2864 | Calling this method immediately repaints the invalidated area of the window | |
2865 | while this would usually only happen when the flow of control returns to the | |
2866 | event loop. Notice that this function doesn't refresh the window and does | |
2867 | nothing if the window hadn't been already repainted. Use | |
2868 | \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the | |
2869 | window unconditionally. | |
2870 | ||
2871 | \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui} | |
2872 | ||
2873 | \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE_UI_NONE}} | |
2874 | ||
2875 | This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to | |
2876 | the window. The particular implementation depends on the window; for | |
2877 | example a wxToolBar will send an update UI event for each toolbar button, | |
2878 | and a wxFrame will send an update UI event for each menubar menu item. | |
2879 | You can call this function from your application to ensure that your | |
2880 | UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers | |
2881 | are concerned). This may be necessary if you have called | |
2882 | \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or | |
2883 | \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to | |
2884 | limit the overhead that wxWindows incurs by sending update UI events in idle time. | |
2885 | ||
2886 | {\it flags} should be a bitlist of one or more of the following values. | |
2887 | ||
2888 | \begin{verbatim} | |
2889 | enum wxUpdateUI | |
2890 | { | |
2891 | wxUPDATE_UI_NONE = 0x0000, // No particular value | |
2892 | wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants | |
2893 | wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle | |
2894 | }; | |
2895 | \end{verbatim} | |
2896 | ||
2897 | If you are calling this function from an OnInternalIdle or OnIdle | |
2898 | function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since | |
2899 | this tells the window to only update the UI elements that need | |
2900 | to be updated in idle time. Some windows update their elements | |
2901 | only when necessary, for example when a menu is about to be shown. | |
2902 | The following is an example of how to call UpdateWindowUI from | |
2903 | an idle function. | |
2904 | ||
2905 | \begin{verbatim} | |
2906 | void MyWindow::OnInternalIdle() | |
2907 | { | |
2908 | if (wxUpdateUIEvent::CanUpdate(this)) | |
2909 | UpdateWindowUI(wxUPDATE_UI_FROMIDLE); | |
2910 | } | |

2924 | ||
2925 | If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set, | |

2927 | ||
2928 | \wxheading{Return value} | |
