}}\label{wxwindow
}
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.
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.
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.

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

103 descend into all subwindows.
}
104 \twocolitem{\windowstyle{wxWS
\_EX\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the
105 parent window and so on recursively by default. Using this flag for the
106 given window allows to block this propagation at this window, i.e. prevent
107 the events from being propagated further upwards. Dialogs have this
109 \twocolitem{\windowstyle{wxWS
\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must
110 be used with transient windows as otherwise there is the risk of creating a
111 dialog/frame with this window as a parent which would lead to a crash if the
112 parent is destroyed before the child.
}
113 \twocolitem{\windowstyle{wxWS
\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even
114 if the mode set by

230 and when the mouse is released the capture returns to the window which had had
231 captured it previously and it is only really released if there were no previous
232 window. In particular, this means that you must release the mouse as many times
233 as you capture it, unless the window receives
234 the
\helpref{wxMouseCaptureLostEvent

236 Any application which captures the mouse in the beginning of some operation

}{\param{bool

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

418 Converts a point or size from dialog units to pixels.
420 For the x dimension, the dialog units are multiplied by the average character width
421 and then divided by
4.
423 For the y dimension, the dialog units are multiplied by the average character height
424 and then divided by
8.
428 Dialog units are used for maintaining a dialog's proportions even if the font changes.
430 You can also use these functions programmatically. A convenience macro is defined:

498 have been processed. This prevents problems with events being sent to non-existent

860 \func{static wxVisualAttributes

862 Returns the default font and colours which are used by the control. This is
863 useful if you want to use the same font or colour in your own control as in a
864 standard control -- which is a much better idea than hard coding specific
865 colours or fonts which might look completely out of place on the users
866 system, especially if it uses themes.
868 The
\arg{variant

869 ignore under other platforms. Under Mac, it will change the size of the
870 returned font. See
\helpref{wxWindow::SetWindowVariant
}{wxwindowsetwindowvariant

873 This static method is ``overridden'' in many derived classes and so calling,
874 for example,
\helpref{wxButton
}{wxbutton

875 return the values appropriate for a button which will be normally different
876 from those returned by, say,
\helpref{wxListCtrl

878 The
\texttt{wxVisualAttributes
} structure has at least the fields
879 \texttt{font
},
\texttt{colFg
} and
\texttt{colBg

880 if it was not possible to determine the default control appearance or,

}{wxwindowgetclassdefaultattributes
}(
\helpref{GetWindowVariant

959 One advantage of using this function compared to the static version is that
960 the call is automatically dispatched to the correct class (as usual with
961 virtual functions) and you don't have to specify the class name explicitly.
963 The other one is that in the future this function could return different
964 results, for example it might return a different font for an ``Ok'' button
965 than for a generic button if the users GUI is configured to show such buttons
966 in bold font. Of course, the down side is that it is impossible to call this
967 function without actually having an object to apply it to whereas the static
968 version can be used without having to create an object first.

}{\void}
1516 This function is (or should be, in case of custom controls) called during
1517 window creation to intelligently set up the window visual attributes, that is
1518 the font and the foreground and background colours.
1520 By ``intelligently'' the following is meant: by default, all windows use their
1521 own
\helpref{default
}{wxwindowgetclassdefaultattributes
} attributes. However
1522 if some of the parents attributes are explicitly (that is, using
1523 \helpref{SetFont
}{wxwindowsetfont
} and not
1524 \helpref{SetOwnFont
}{wxwindowsetownfont
}) changed
\emph{and
} if the
1525 corresponding attribute hadn't been explicitly set for this window itself,
1526 then this window takes the same value as used by the parent. In addition, if
1527 the window overrides
\helpref{ShouldInheritColours
}{wxwindowshouldinheritcolours
}
1528 to return
\false, the colours will not be changed no matter what and only the
1531 This rather complicated logic is necessary in order to accommodate the
1532 different usage scenarios. The most common one is when all default attributes
1533 are used and in this case, nothing should be inherited as in modern GUIs
1534 different controls use different fonts (and colours) than their siblings so
1535 they can't inherit the same value from the parent. However it was also deemed
1536 desirable to allow to simply change the attributes of all children at once by
1537 just changing the font or colour of their common parent, hence in this case we
1538 do inherit the parents attributes.

3209 Let's say you wish to display
50 lines of text, using the same font.
3210 The window is sized so that you can only see
16 lines at a time.
3216 SetScrollbar(wxVERTICAL,
0,
16,
50);
3220 Note that with the window at this size, the thumb position can never go
3221 above
50 minus
16, or
34.
3223 You can determine how many lines are currently visible by dividing the current view
3224 size by the character height in pixels.
3226 When defining your own scrollbar behaviour, you will always need to recalculate
3227 the scrollbar settings when the window size changes. You could therefore put your
3228 scrollbar calculations and SetScrollbar
3229 call into a function named AdjustScrollbars, which can be called initially and also
3230 from your

3257 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3258 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3259 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3260 value has to be adjusted when the window is resized, since the page size will have changed.
3262 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3263 the thumb changes size to reflect the page size relative to the length of the
document. When the
3264 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3265 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3268 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3269 handling of pages and ranges.

3325 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3326 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3327 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3328 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3329 and usually the scrollbar will be automatically hidden.

3719 \func{virtual void
}{Update
}{\void}
3721 Calling this method immediately repaints the invalidated area of the window and
3722 all of its children recursively while this would usually only happen when the
3723 flow of control returns to the event loop.
3724 Notice that this function doesn't invalidate any area of the window so
3725 nothing happens if nothing has been invalidated (i.e. marked as requiring
3726 a redraw). Use
\helpref{Refresh
}{wxwindowrefresh
} first if you want to
3727 immediately redraw the window unconditionally.

}\label{wxwindowupdatewindowui
}
3732 \func{virtual void
}{UpdateWindowUI
}{\param{long
}{ flags = wxUPDATE
\_UI\_NONE}}
3734 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
3735 the window. The particular implementation depends on the window; for
3736 example a wxToolBar will send an update UI event for each toolbar button,
3737 and a wxFrame will send an update UI event for each menubar menu item.
3738 You can call this function from your application to ensure that your
3739 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3740 are concerned). This may be necessary if you have called
3741 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
3742 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval
} to
3743 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3745 {\it flags
} should be a bitlist of one or more of the following values.
3750 wxUPDATE_UI_NONE =
0x0000, // No particular value
3751 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
3752 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
3756 If you are calling this function from an OnInternalIdle or OnIdle
3757 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
3758 this tells the window to only update the UI elements that need
3759 to be updated in idle time. Some windows update their elements
3760 only when necessary, for example when a menu is about to be shown.
3761 The following is an example of how to call UpdateWindowUI from
3765 void MyWindow::OnInternalIdle()
3767 if (wxUpdateUIEvent::CanUpdate(this))
3768 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);

3786 the method will also call Validate() of all child windows.
