13 | ||
14 | wxWindow is the base class for all windows and represents any visible object on | |
15 | screen. All controls, top level windows and so on are windows. Sizers and | |
16 | device contexts are not, however, as they don't appear on screen themselves. | |
17 | ||
18 | Please note that all children of the window will be deleted automatically by | |
19 | the destructor before the window itself is deleted which means that you don't | |
20 | have to worry about deleting them manually. Please see the \helpref{window | |
21 | deletion overview}{windowdeletionoverview} for more information. | |
22 | ||
23 | Also note that in this, and many others, wxWidgets classes some | |
24 | \texttt{GetXXX()} methods may be overloaded (as, for example, | |
25 | \helpref{GetSize}{wxwindowgetsize} or | |
26 | \helpref{GetClientSize}{wxwindowgetclientsize}). In this case, the overloads | |
27 | are non-virtual because having multiple virtual functions with the same name | |
28 | results in a virtual function name hiding at the derived class level (in | |
29 | English, this means that the derived class has to override all overloaded | |
30 | variants if it overrides any of them). To allow overriding them in the derived | |
31 | class, wxWidgets uses a unique protected virtual \texttt{DoGetXXX()} method | |
32 | and all \texttt{GetXXX()} ones are forwarded to it, so overriding the former | |
33 | changes the behaviour of the latter. | |

50 | The following styles can apply to all windows, although they will not always make sense for a particular | |
51 | window class or on all platforms. | |
52 | ||
53 | \twocolwidtha{5cm}% | |
54 | \begin{twocollist}\itemsep=0pt | |
55 | \twocolitem{\windowstyle{wxBORDER\_SIMPLE}}{Displays a thin border around the window. wxSIMPLE\_BORDER is the old name | |
56 | for this style. } | |
57 | \twocolitem{\windowstyle{wxBORDER\_DOUBLE}}{Displays a double border. wxDOUBLE\_BORDER is the old name for this style. Windows and Mac only.} | |
58 | \twocolitem{\windowstyle{wxBORDER\_SUNKEN}}{Displays a sunken border. wxSUNKEN\_BORDER is the old name for this style.} | |
59 | \twocolitem{\windowstyle{wxBORDER\_RAISED}}{Displays a raised border. wxRAISED\_BORDER is the old name for this style. } | |
60 | \twocolitem{\windowstyle{wxBORDER\_STATIC}}{Displays a border suitable for a static control. wxSTATIC\_BORDER is the old name for this style. Windows only. } | |
61 | \twocolitem{\windowstyle{wxBORDER\_THEME}}{Displays a themed border where possible. Currently this has an effect on Windows XP and above only. | |
62 | For more information on themed borders, please see \helpref{Themed borders on Windows}{wxmswthemedborders}.} | |
63 | \twocolitem{\windowstyle{wxBORDER\_NONE}}{Displays no border, overriding the default border style for the window. wxNO\_BORDER is the old name for this style.} | |
64 | \twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint | |
65 | events. Windows only.} | |
66 | \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.} | |
67 | \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that | |
68 | the window wants to get all char/key events for all keys - even for | |
69 | keys like TAB or ENTER which are usually used for dialog navigation | |
70 | and which wouldn't be generated without this style. If you need to | |
71 | use this style in order to get the arrows or etc., but would still like | |
72 | to have normal keyboard navigation take place, you should call | |
73 | \helpref{Navigate}{wxwindownavigate} in response to the key events for | |
74 | Tab and Shift-Tab.} | |
75 | \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{On Windows, this style used to disable repainting | |
76 | the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete | |
77 | and no longer has an effect.} | |
78 | \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical | |
79 | scrollbar. Notice that this style cannot be used with native controls | |
80 | which don't support scrollbars nor with top-level windows in most ports.} | |
81 | \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal | |
82 | scrollbar. The same limitations as for wxVSCROLL apply to this style.} | |
83 | \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars, | |
84 | disable them instead of hiding them when they are not needed (i.e. when the | |
85 | size of the window is big enough to not require the scrollbars to navigate it). | |
86 | This style is currently implemented for wxMSW, wxGTK and wxUniversal and does | |
87 | nothing on the other platforms.} | |
88 | \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being | |
89 | repainted, then children being painted over them. Windows only.} | |
90 | \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force | |
91 | a complete redraw of the window whenever it is resized instead of redrawing | |
92 | just the part of the window affected by resizing. Note that this was the | |
93 | behaviour by default before 2.5.1 release and that if you experience redraw | |
94 | problems with code which previously used to work you may want to try this. | |
95 | Currently this style applies on GTK+ 2 and Windows only, and full repainting is always | |
96 | done on other platforms.} | |

105 | \twocolwidtha{5cm}% | |
106 | \begin{twocollist}\itemsep=0pt | |
107 | \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{By default, Validate/TransferDataTo/FromWindow() | |
108 | only work on direct children of the window (compatible behaviour). Set this flag to make them recursively | |
109 | descend into all subwindows.} | |
110 | \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the | |
111 | parent window and so on recursively by default. Using this flag for the | |
112 | given window allows to block this propagation at this window, i.e. prevent | |
113 | the events from being propagated further upwards. Dialogs have this | |
114 | flag on by default.} | |
115 | \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must | |
116 | be used with transient windows as otherwise there is the risk of creating a | |
117 | dialog/frame with this window as a parent which would lead to a crash if the | |
118 | parent is destroyed before the child.} | |
119 | \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even | |
120 | if the mode set by \helpref{wxIdleEvent::SetMode}{wxidleeventsetmode} is wxIDLE\_PROCESS\_SPECIFIED.} | |
121 | \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_UI\_UPDATES}}{This window should always process UI update events, | |
122 | even if the mode set by \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} is wxUPDATE\_UI\_PROCESS\_SPECIFIED.} | |

133 | \membersection{wxWindow::wxWindow}\label{wxwindowctor} | |
134 | ||
135 | \func{}{wxWindow}{\void} | |
136 | ||
137 | Default constructor. | |

139 | \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id}, | |
140 | \param{const wxPoint\& }{pos = wxDefaultPosition}, | |

142 | \param{long }{style = 0}, | |
143 | \param{const wxString\& }{name = wxPanelNameStr}} | |
144 | ||
145 | Constructs a window, which can be a child of a frame, dialog or any other non-control window. | |
146 | ||
147 | \wxheading{Parameters} | |
148 | ||
149 | \docparam{parent}{Pointer to a parent window.} | |
150 | ||
151 | \docparam{id}{Window identifier. If wxID\_ANY, will automatically create an identifier.} | |
152 | ||
153 | \docparam{pos}{Window position. wxDefaultPosition indicates that wxWidgets | |
154 | should generate a default position for the window. If using the wxWindow class directly, supply | |
155 | an actual position.} | |
156 | ||
157 | \docparam{size}{Window size. wxDefaultSize indicates that wxWidgets | |
158 | should generate a default size for the window. If no suitable size can be found, the | |
159 | window will be sized to 20x20 pixels so that the window is visible but obviously not | |
160 | correctly sized. } | |

166 | ||
167 | \membersection{wxWindow::\destruct{wxWindow}}\label{wxwindowdtor} | |
168 | ||
169 | \func{}{\destruct{wxWindow}}{\void} | |
170 | ||
171 | Destructor. Deletes all subwindows, then deletes itself. Instead of using | |
172 | the {\bf delete} operator explicitly, you should normally | |
173 | use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWidgets | |
174 | can delete a window only when it is safe to do so, in idle time. | |

182 | ||
183 | \membersection{wxWindow::AcceptsFocus}\label{wxwindowacceptsfocus} | |
184 | ||
185 | \constfunc{bool}{AcceptsFocus}{\void} | |
186 | ||
187 | This method may be overridden in the derived classes to return \false to | |
188 | indicate that this control doesn't accept input at all (i.e. behaves like e.g. | |
189 | \helpref{wxStaticText}{wxstatictext}) and so doesn't need focus. | |
190 | ||
191 | \wxheading{See also} | |

196 | \membersection{wxWindow::AcceptsFocusFromKeyboard}\label{wxwindowacceptsfocusfromkeyboard} | |
197 | ||
198 | \constfunc{bool}{AcceptsFocusFromKeyboard}{\void} | |
199 | ||
200 | This method may be overridden in the derived classes to return \false to | |
201 | indicate that while this control can, in principle, have focus if the user | |
202 | clicks it with the mouse, it shouldn't be included in the TAB traversal chain | |
203 | when using the keyboard. | |
204 | ||
205 | ||
206 | \membersection{wxWindow::AddChild}\label{wxwindowaddchild} | |
207 | ||
208 | \func{virtual void}{AddChild}{\param{wxWindow* }{child}} | |
209 | ||
210 | Adds a child window. This is called automatically by window creation | |
211 | functions so should not be required by the application programmer. | |
212 | ||
213 | Notice that this function is mostly internal to wxWidgets and shouldn't be | |
214 | called by the user code. | |
215 | ||
216 | \wxheading{Parameters} | |
217 | ||
218 | \docparam{child}{Child window to add.} | |
219 | ||
220 | ||
221 | \membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize} | |
222 | ||
223 | \constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}} | |
224 | ||
225 | Sets the cached best size value. | |
226 | ||
227 | ||
228 | \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse} | |
229 | ||
230 | \func{virtual void}{CaptureMouse}{\void} | |
231 | ||
232 | Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to | |
233 | release the capture. | |
234 | ||
235 | Note that wxWidgets maintains the stack of windows having captured the mouse | |
236 | and when the mouse is released the capture returns to the window which had had | |
237 | captured it previously and it is only really released if there were no previous | |
238 | window. In particular, this means that you must release the mouse as many times | |
239 | as you capture it, unless the window receives | |
240 | the \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent} event. | |
241 | ||
242 | Any application which captures the mouse in the beginning of some operation | |
243 | {\em must} handle \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent} | |
244 | and cancel this operation when it receives the event. The event handler must | |
245 | not recapture mouse. | |

253 | \membersection{wxWindow::Center}\label{wxwindowcenter} | |
254 | ||
255 | \func{void}{Center}{\param{int}{ direction}} | |
256 | ||
257 | A synonym for \helpref{Centre}{wxwindowcentre}. | |
258 | ||
259 | ||
260 | \membersection{wxWindow::CenterOnParent}\label{wxwindowcenteronparent} | |
261 | ||
262 | \func{void}{CenterOnParent}{\param{int}{ direction}} | |
263 | ||
264 | A synonym for \helpref{CentreOnParent}{wxwindowcentreonparent}. | |
265 | ||
266 | ||
267 | \membersection{wxWindow::CenterOnScreen}\label{wxwindowcenteronscreen} | |
268 | ||
269 | \func{void}{CenterOnScreen}{\param{int}{ direction}} | |
270 | ||
271 | A synonym for \helpref{CentreOnScreen}{wxwindowcentreonscreen}. | |
272 | ||
273 | ||
274 | \membersection{wxWindow::Centre}\label{wxwindowcentre} | |
275 | ||
276 | \func{void}{Centre}{\param{int}{ direction = wxBOTH}} | |
277 | ||
278 | Centres the window. | |
279 | ||
280 | \wxheading{Parameters} | |
281 | ||
282 | \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp | |
283 | or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag | |
284 | if you want to center the window on the entire screen and not on its | |
285 | parent window.} | |
286 | ||
287 | The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer | |
288 | (it has no effect). | |
289 | ||
290 | \wxheading{Remarks} | |
291 | ||
292 | If the window is a top level one (i.e. doesn't have a parent), it will be | |
293 | centered relative to the screen anyhow. | |
294 | ||

300 | \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent} | |
301 | ||
302 | \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}} | |
303 | ||
304 | Centres the window on its parent. This is a more readable synonym for | |
305 | \helpref{Centre}{wxwindowcentre}. | |
306 | ||
307 | \wxheading{Parameters} | |
308 | ||
309 | \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp | |
310 | or {\tt wxBOTH}.} | |
311 | ||
312 | \wxheading{Remarks} | |
313 | ||
314 | This methods provides for a way to center top level windows over their | |
315 | parents instead of the entire screen. If there is no parent or if the | |
316 | window is not a top level window, then behaviour is the same as | |
317 | \helpref{wxWindow::Centre}{wxwindowcentre}. | |
318 | ||
319 | \wxheading{See also} | |

324 | \membersection{wxWindow::CentreOnScreen}\label{wxwindowcentreonscreen} | |
325 | ||
326 | \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}} | |
327 | ||
328 | Centres the window on screen. This only works for top level windows - | |
329 | otherwise, the window will still be centered on its parent. | |
330 | ||
331 | \wxheading{Parameters} | |
332 | ||

341 | \membersection{wxWindow::ClearBackground}\label{wxwindowclearbackground} | |
342 | ||
343 | \func{void}{ClearBackground}{\void} | |
344 | ||
345 | Clears the window by filling it with the current background colour. Does not | |
346 | cause an erase background event to be generated. | |
347 | ||
348 | ||
349 | \membersection{wxWindow::ClientToScreen}\label{wxwindowclienttoscreen} | |

352 | ||
353 | \perlnote{In wxPerl this method returns a 2-element list instead of | |
354 | modifying its parameters.} | |
355 | ||
356 | \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}} | |
357 | ||
358 | Converts to screen coordinates from coordinates relative to this window. | |
359 | ||
360 | \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and | |

377 | \membersection{wxWindow::Close}\label{wxwindowclose} | |
378 | ||
379 | \func{bool}{Close}{\param{bool}{ force = {\tt false}}} | |
380 | ||
381 | This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose | |
382 | handler usually tries to close the window. It doesn't close the window itself, | |
383 | however. | |
384 | ||
385 | \wxheading{Parameters} | |
386 | ||
387 | \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction | |
388 | of this window, {\tt true} if it cannot.} | |
389 | ||
390 | \wxheading{Remarks} | |
391 | ||
392 | Close calls the \helpref{close handler}{wxcloseevent} for the window, providing | |
393 | an opportunity for the window to choose whether to destroy the window. | |
394 | Usually it is only used with the top level windows (wxFrame and wxDialog | |
395 | classes) as the others are not supposed to have any special OnClose() logic. | |
396 | ||
397 | The close handler should check whether the window is being deleted forcibly, | |
398 | using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it | |
399 | should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}. | |
400 | ||
401 | {\it Note} that calling Close does not guarantee that the window will be | |
402 | destroyed; but it provides a way to simulate a manual close of a window, which | |
403 | may or may not be implemented by destroying the window. The default | |
404 | implementation of wxDialog::OnCloseWindow does not necessarily delete the | |
405 | dialog, since it will simply simulate an wxID\_CANCEL event which is handled by | |
406 | the appropriate button event handler and may do anything at all. | |
407 | ||
408 | To guarantee that the window will be destroyed, call | |
409 | \helpref{wxWindow::Destroy}{wxwindowdestroy} instead | |

420 | \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}} | |
421 | ||
422 | \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}} | |
423 | ||
424 | Converts a point or size from dialog units to pixels. | |
425 | ||
426 | For the x dimension, the dialog units are multiplied by the average character width | |
427 | and then divided by 4. | |
428 | ||
429 | For the y dimension, the dialog units are multiplied by the average character height | |
430 | and then divided by 8. | |
431 | ||
432 | \wxheading{Remarks} | |
433 | ||
434 | Dialog units are used for maintaining a dialog's proportions even if the font changes. | |
435 | ||
436 | You can also use these functions programmatically. A convenience macro is defined: | |
437 | ||
438 | {\small | |
439 | \begin{verbatim} | |
440 | #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt) | |

726 | This method is useful for visual appearance optimization (for example, it | |

867 | ||
868 | Returns the default font and colours which are used by the control. This is | |
869 | useful if you want to use the same font or colour in your own control as in a | |
870 | standard control -- which is a much better idea than hard coding specific | |
871 | colours or fonts which might look completely out of place on the users | |
872 | system, especially if it uses themes. | |
873 | ||
874 | The \arg{variant} parameter is only relevant under Mac currently and is | |
875 | ignore under other platforms. Under Mac, it will change the size of the | |
876 | returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant} | |
877 | for more about this. | |
878 | ||
879 | This static method is ``overridden'' in many derived classes and so calling, | |
880 | for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically | |
881 | return the values appropriate for a button which will be normally different | |
882 | from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes(). | |
883 | ||
884 | The \texttt{wxVisualAttributes} structure has at least the fields | |
885 | \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid | |
886 | if it was not possible to determine the default control appearance or, | |
887 | especially for the background colour, if the field doesn't make sense as is | |
888 | the case for \texttt{colBg} for the controls with themed background. | |

959 | ||
960 | \constfunc{virtual wxVisualAttributes}{GetDefaultAttributes}{\void} | |
961 | ||
962 | Currently this is the same as calling | |
963 | \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()). | |
964 | ||
965 | One advantage of using this function compared to the static version is that | |
966 | the call is automatically dispatched to the correct class (as usual with | |
967 | virtual functions) and you don't have to specify the class name explicitly. | |
968 | ||
969 | The other one is that in the future this function could return different | |
970 | results, for example it might return a different font for an ``Ok'' button | |
971 | than for a generic button if the users GUI is configured to show such buttons | |
972 | in bold font. Of course, the down side is that it is impossible to call this | |
973 | function without actually having an object to apply it to whereas the static | |
974 | version can be used without having to create an object first. | |

1503 | Returns \true if this window background is transparent (as, for example, for | |
1504 | wxStaticText) and should show the parent window background. | |
1505 | ||
1506 | This method is mostly used internally by the library itself and you normally | |
1507 | shouldn't have to call it. You may, however, have to override it in your | |
1508 | wxWindow-derived class to ensure that background is painted correctly. | |
1509 | ||
1510 | ||
1511 | \membersection{wxWindow::Hide}\label{wxwindowhide} | |

1518 | \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes} | |
1519 | ||
1520 | \func{void}{InheritAttributes}{\void} | |
1521 | ||
1522 | This function is (or should be, in case of custom controls) called during | |
1523 | window creation to intelligently set up the window visual attributes, that is | |
1524 | the font and the foreground and background colours. | |
1525 | ||
1526 | By ``intelligently'' the following is meant: by default, all windows use their | |
1527 | own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However | |
1528 | if some of the parents attributes are explicitly (that is, using | |
1529 | \helpref{SetFont}{wxwindowsetfont} and not | |
1530 | \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the | |
1531 | corresponding attribute hadn't been explicitly set for this window itself, | |
1532 | then this window takes the same value as used by the parent. In addition, if | |
1533 | the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours} | |
1534 | to return \false, the colours will not be changed no matter what and only the | |
1535 | font might. | |
1536 | ||
1537 | This rather complicated logic is necessary in order to accommodate the | |
1538 | different usage scenarios. The most common one is when all default attributes | |
1539 | are used and in this case, nothing should be inherited as in modern GUIs | |
1540 | different controls use different fonts (and colours) than their siblings so | |
1541 | they can't inherit the same value from the parent. However it was also deemed | |
1542 | desirable to allow to simply change the attributes of all children at once by | |
1543 | just changing the font or colour of their common parent, hence in this case we | |
1544 | do inherit the parents attributes. | |

1567 | any drawing done on the window is really done on a temporary backing surface | |
1568 | and transferred to the screen all at once later. | |

2315 | This virtual function is normally only used internally, but | |
2316 | sometimes an application may need it to implement functionality | |
2317 | that should not be disabled by an application defining an OnIdle | |
2318 | handler in a derived class. | |

2320 | This function may be used to do delayed painting, for example, | |

2359 | \func{bool}{PopupMenu}{\param{wxMenu* }{menu}, \param{int }{x}, \param{int }{y}} | |
2360 | ||
2361 | Pops up the given menu at the specified coordinates, relative to this | |
2362 | window, and returns control when the user has dismissed the menu. If a | |
2363 | menu item is selected, the corresponding menu event is generated and will be | |
2364 | processed as usually. If the coordinates are not specified, current mouse | |
2365 | cursor position is used. | |

2384 | is called to ensure that the menu items are in the correct state. The menu does | |
2385 | not get deleted by the window. | |
2386 | ||
2387 | It is recommended to not explicitly specify coordinates when calling PopupMenu | |
2388 | in response to mouse click, because some of the ports (namely, wxGTK) can do | |

2416 | \docparam{handler}{Specifies the handler to be pushed.} | |
2417 | ||
2418 | \wxheading{Remarks} | |
2419 | ||
2420 | An event handler is an object that is capable of processing the events | |
2421 | sent to a window. By default, the window is its own event handler, but | |
2422 | an application may wish to substitute another, for example to allow | |
2423 | central implementation of event-handling for a variety of different | |
2424 | window classes. | |
2425 | ||
2426 | \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows | |
2427 | an application to set up a chain of event handlers, where an event not handled by one event handler is | |
2428 | handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to | |
2429 | remove the event handler. | |

2455 | \func{virtual void}{Refresh}{\param{bool}{ eraseBackground = {\tt true}}, \param{const wxRect* }{rect = NULL}} | |
2456 | ||
2457 | Causes this window, and all of its children recursively (except under wxGTK1 | |
2458 | where this is not implemented), to be repainted. Note that repainting doesn't | |
2459 | happen immediately but only during the next event loop iteration, if you need | |
2460 | to update the window immediately you should use \helpref{Update}{wxwindowupdate} | |
2461 | instead. | |

2479 | ||
2480 | Redraws the contents of the given rectangle: only the area inside it will be | |
2481 | repainted. | |
2482 | ||
2483 | This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax | |
2484 | as it can be called with a temporary wxRect object as argument like this | |

2491 | ||
2492 | Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window | |
2493 | will receive a hotkey event. It will receive the event even if the application is in the background | |
2494 | and does not have the input focus because the user is working with some other application. | |

2511 | ||
2512 | \wxheading{Remarks} | |
2513 | ||

2741 | The background colour is usually painted by the default\rtfsp | |
2742 | \helpref{wxEraseEvent}{wxeraseevent} event handler function | |
2743 | under Windows and automatically under GTK. | |
2744 | ||
2745 | Note that setting the background colour does not cause an immediate refresh, so you | |
2746 | may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after | |
2747 | calling this function. | |
2748 | ||
2749 | Using this function will disable attempts to use themes for this | |
2750 | window, if the system supports them. Use with care since usually the | |
2751 | themes represent the appearance chosen by the user to be used for all | |
2752 | applications on the system. | |

2765 | ||
2766 | \func{virtual void}{SetBackgroundStyle}{\param{wxBackgroundStyle}{ style}} | |
2767 | ||
2768 | Sets the background style of the window. The background style indicates | |
2769 | whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM), | |
2770 | be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the | |
2771 | application to implement (wxBG\_STYLE\_CUSTOM). | |
2772 | ||
2773 | On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom | |
2774 | background, such as a tiled bitmap. Currently the style has no effect on other platforms. | |

2785 | \func{void}{SetInitialSize}{\param{const wxSize\& }{size = wxDefaultSize}} | |
2786 | ||
2787 | A {\it smart} SetSize that will fill in default size components with the | |
2788 | window's {\it best} size values. Also sets the window's minsize to | |
2789 | the value passed in for use with sizers. This means that if a full or | |
2790 | partial size is passed to this function then the sizers will use that | |
2791 | size instead of the results of GetBestSize to determine the minimum | |
2792 | needs of the window for layout. | |
2793 | ||
2794 | Most controls will use this to set their initial size, and their min | |
2795 | size to the passed in value (if any.) | |

2817 | ||
2818 | This sets the size of the window client area in pixels. Using this function to size a window | |
2819 | tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not | |
2820 | worry about what dimensions the border or title bar have when trying to fit the window | |

2843 | ||
2844 | Sets the window to have the given layout constraints. The window | |
2845 | will then own the object, and will take care of its deletion. | |
2846 | If an existing layout constraints object is already owned by the | |
2847 | window, it will be deleted. | |

2854 | \wxheading{Remarks} | |
2855 | ||
2856 | You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use | |
2857 | the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout() | |
2858 | explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the | |

2865 | This normally does not need to be called by user code. It is called | |

2921 | \docparam{handler}{Specifies the handler to be set.} | |
2922 | ||
2923 | \wxheading{Remarks} | |
2924 | ||
2925 | An event handler is an object that is capable of processing the events | |
2926 | sent to a window. By default, the window is its own event handler, but | |
2927 | an application may wish to substitute another, for example to allow | |
2928 | central implementation of event-handling for a variety of different | |
2929 | window classes. | |
2930 | ||
2931 | It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since | |
2932 | this sets up a chain of event handlers, where an event not handled by one event handler is | |
2933 | handed to the next one in the chain. | |

2955 | window if it has this style flag set.} | |
2956 | \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command | |
2957 | events are propagated upwards to the window parent recursively until a handler | |
2958 | for them is found. Using this style allows to prevent them from being | |
2959 | propagated beyond this window. Notice that wxDialog has this style on by | |
2960 | default for the reasons explained in the | |
2961 | \helpref{event processing overview}{eventprocessing}.} | |
2962 | \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a | |
2963 | window from being used as an implicit parent for the dialogs which were | |
2964 | created without a parent. It is useful for the windows which can disappear at | |
2965 | any moment as creating children of such windows results in fatal problems.} | |
2966 | \twocolitem{\windowstyle{wxWS\_EX\_CONTEXTHELP}}{Under Windows, puts a query | |

2969 | application window. | |
2970 | This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so | |

2996 | This function is called by wxWidgets keyboard navigation code when the user | |
2997 | gives the focus to this window from keyboard (e.g. using {\tt TAB} key). | |

3213 | \wxheading{Remarks} | |
3214 | ||
3215 | Let's say you wish to display 50 lines of text, using the same font. | |
3216 | The window is sized so that you can only see 16 lines at a time. | |
3217 | ||
3218 | You would use: | |
3219 | ||
3220 | {\small% | |
3221 | \begin{verbatim} | |
3222 | SetScrollbar(wxVERTICAL, 0, 16, 50); | |
3223 | \end{verbatim} | |
3224 | } | |
3225 | ||
3226 | Note that with the window at this size, the thumb position can never go | |
3227 | above 50 minus 16, or 34. | |
3228 | ||
3229 | You can determine how many lines are currently visible by dividing the current view | |
3230 | size by the character height in pixels. | |
3231 | ||
3232 | When defining your own scrollbar behaviour, you will always need to recalculate | |
3233 | the scrollbar settings when the window size changes. You could therefore put your | |
3234 | scrollbar calculations and SetScrollbar | |
3235 | call into a function named AdjustScrollbars, which can be called initially and also | |
3236 | from your \helpref{wxSizeEvent}{wxsizeevent} handler function. | |

3260 | ||
3261 | \wxheading{Remarks} | |
3262 | ||
3263 | The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you | |
3264 | click on the area above/left of or below/right of the thumb. Normally you will want a whole visible | |
3265 | page to be scrolled, i.e. the size of the current view (perhaps the window client size). This | |
3266 | value has to be adjusted when the window is resized, since the page size will have changed. | |
3267 | ||
3268 | In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows | |
3269 | the thumb changes size to reflect the page size relative to the length of the document. When the | |
3270 | document size is only slightly bigger than the current view (window) size, almost all of the scrollbar | |
3271 | will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems) | |
3272 | disappear. | |
3273 | ||
3274 | Currently, this function should be called before SetPageRange, because of a quirk in the Windows | |
3275 | handling of pages and ranges. | |

3330 | ||
3331 | The range of a scrollbar is the number of steps that the thumb may travel, rather than the total | |
3332 | object length of the scrollbar. If you are implementing a scrolling window, for example, you | |
3333 | would adjust the scroll range when the window is resized, by subtracting the window view size from the | |
3334 | total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero | |
3335 | and usually the scrollbar will be automatically hidden. | |

3647 | Turns the given \arg{flag} on if it's currently turned off and vice versa. | |

3724 | ||
3725 | \func{virtual void}{Update}{\void} | |
3726 | ||
3727 | Calling this method immediately repaints the invalidated area of the window and | |
3728 | all of its children recursively while this would usually only happen when the | |
3729 | flow of control returns to the event loop. | |
3730 | Notice that this function doesn't invalidate any area of the window so | |
3731 | nothing happens if nothing has been invalidated (i.e. marked as requiring | |
3732 | a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to | |
3733 | immediately redraw the window unconditionally. | |

3737 | ||
3738 | \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}} | |
3739 | ||
3740 | This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to | |
3741 | the window. The particular implementation depends on the window; for | |
3742 | example a wxToolBar will send an update UI event for each toolbar button, | |
3743 | and a wxFrame will send an update UI event for each menubar menu item. | |
3744 | You can call this function from your application to ensure that your | |
3745 | UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers | |
3746 | are concerned). This may be necessary if you have called | |
3747 | \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or | |
3748 | \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to | |
3749 | limit the overhead that wxWidgets incurs by sending update UI events in idle time. | |
3750 | ||
3751 | {\it flags} should be a bitlist of one or more of the following values. | |
3752 | ||
3753 | \begin{verbatim} | |
3754 | enum wxUpdateUI | |
3755 | { | |
3756 | wxUPDATE_UI_NONE = 0x0000, // No particular value | |
3757 | wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants | |
3758 | wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle | |
3759 | }; | |
3760 | \end{verbatim} | |
3761 | ||
3762 | If you are calling this function from an OnInternalIdle or OnIdle | |
3763 | function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since | |
3764 | this tells the window to only update the UI elements that need | |
3765 | to be updated in idle time. Some windows update their elements | |
3766 | only when necessary, for example when a menu is about to be shown. | |
3767 | The following is an example of how to call UpdateWindowUI from | |
3768 | an idle function. | |
3769 | ||
3770 | \begin{verbatim} | |
3771 | void MyWindow::OnInternalIdle() | |
3772 | { | |
3773 | if (wxUpdateUIEvent::CanUpdate(this)) | |
3774 | UpdateWindowUI(wxUPDATE_UI_FROMIDLE); | |
3775 | } | |

3787 | \func{virtual bool}{Validate}{\void} | |

3790 | ||
3791 | If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set, | |
3792 | the method will also call Validate() of all child windows. | |
3793 | ||
3794 | \wxheading{Return value} | |
