}}\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 to have
66 normal keyboard navigation take place, you should create and send a
67 wxNavigationKeyEvent in response to the key events for Tab and
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 scrollbar.
}
73 \twocolitem{\windowstyle{wxHSCROLL
}}{Use this style to enable a horizontal scrollbar.
}
74 \twocolitem{\windowstyle{wxALWAYS
\_SHOW\_SB}}{If a window has scrollbars,
75 disable them instead of hiding them when they are not needed (i.e. when the
76 size of the window is big enough to not require the scrollbars to navigate it).
77 This style is currently implemented for wxMSW, wxGTK and wxUniversal and does
78 nothing on the other platforms.
}
79 \twocolitem{\windowstyle{wxCLIP
\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
80 repainted, then children being painted over them. Windows only.
}
81 \twocolitem{\windowstyle{wxFULL
\_REPAINT\_ON\_RESIZE}}{Use this style to force
82 a complete redraw of the window whenever it is resized instead of redrawing
83 just the part of the window affected by resizing. Note that this was the
84 behaviour by default before
2.5.1 release and that if you experience redraw
85 problems with code which previously used to work you may want to try this.
86 Currently this style applies on GTK+
2 and Windows only, and full repainting is always
87 done on other platforms.

\_EX\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the
102 parent window and so on recursively by default. Using this flag for the
103 given window allows to block this propagation at this window, i.e. prevent
104 the events from being propagated further upwards. Dialogs have this

\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must
107 be used with transient windows as otherwise there is the risk of creating a

109 parent is destroyed before the child.

372 This function simply generates a
\helpref{wxCloseEvent
}{wxcloseevent

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

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

857 \func{static wxVisualAttributes
}{GetClassDefaultAttributes
}{\param{wxWindowVariant
}{ variant =

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

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

}{\void}
1501 This function is (or should be, in case of custom controls) called during
1502 window creation to intelligently set up the window visual attributes, that is
1503 the font and the foreground and background colours.
1505 By ``intelligently'' the following is meant: by default, all windows use their
1506 own
\helpref{default
}{wxwindowgetclassdefaultattributes
} attributes. However
1507 if some of the parents attributes are explicitly (that is, using
1508 \helpref{SetFont
}{wxwindowsetfont
} and not
1509 \helpref{SetOwnFont
}{wxwindowsetownfont
}) changed
\emph{and
} if the
1510 corresponding attribute hadn't been explicitly set for this window itself,
1511 then this window takes the same value as used by the parent. In addition, if
1512 the window overrides
\helpref{ShouldInheritColours
}{wxwindowshouldinheritcolours
}
1513 to return
\false, the colours will not be changed no matter what and only the
1516 This rather complicated logic is necessary in order to accommodate the
1517 different usage scenarios. The most common one is when all default attributes
1518 are used and in this case, nothing should be inherited as in modern GUIs
1519 different controls use different fonts (and colours) than their siblings so
1520 they can't inherit the same value from the parent. However it was also deemed
1521 desirable to allow to simply change the attributes of all children at once by
1522 just changing the font or colour of their common parent, hence in this case we
1523 do inherit the parents attributes.

3174 Let's say you wish to display
50 lines of text, using the same font.
3175 The window is sized so that you can only see
16 lines at a time.
3181 SetScrollbar(wxVERTICAL,
0,
16,
50);
3185 Note that with the window at this size, the thumb position can never go
3186 above
50 minus
16, or
34.
3188 You can determine how many lines are currently visible by dividing the current view
3189 size by the character height in pixels.
3191 When defining your own scrollbar behaviour, you will always need to recalculate
3192 the scrollbar settings when the window size changes. You could therefore put your
3193 scrollbar calculations and SetScrollbar
3194 call into a function named AdjustScrollbars, which can be called initially and also

3222 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3223 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3224 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3225 value has to be adjusted when the window is resized, since the page size will have changed.
3227 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3228 the thumb changes size to reflect the page size relative to the length of the
document. When the
3229 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3230 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3233 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3234 handling of pages and ranges.

3290 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3291 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3292 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3293 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3294 and usually the scrollbar will be automatically hidden.

3628 Transfers values from child controls to data areas specified by their validators. Returns
3629 {\tt false

3631 If the window has
{\tt wxWS
\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3632 the method will also call TransferDataFromWindow() of all child windows.

3663 Unregisters a system wide hotkey.
3665 \wxheading{Parameters
}
3667 \docparam{hotkeyId
}{Numeric identifier of the hotkey. Must be the same id that was passed to RegisterHotKey.

3682 \membersection{wxWindow::Update
}\label{wxwindowupdate
}
3684 \func{virtual void
}{Update
}{\void}
3686 Calling this method immediately repaints the invalidated area of the window and
3687 all of its children recursively while this would usually only happen when the
3688 flow of control returns to the event loop.
3689 Notice that this function doesn't invalidate any area of the window so
3690 nothing happens if nothing has been invalidated (i.e. marked as requiring
3691 a redraw). Use
\helpref{Refresh
}{wxwindowrefresh
} first if you want to
3692 immediately redraw the window unconditionally.
3695 \membersection{wxWindow::UpdateWindowUI
}\label{wxwindowupdatewindowui
}
3697 \func{virtual void
}{UpdateWindowUI
}{\param{long
}{ flags = wxUPDATE
\_UI\_NONE}}
3699 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
3700 the window. The particular implementation depends on the window; for
3701 example a wxToolBar will send an update UI event for each toolbar button,
3702 and a wxFrame will send an update UI event for each menubar menu item.
3703 You can call this function from your application to ensure that your
3704 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3705 are concerned). This may be necessary if you have called
3706 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
3707 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval
} to
3708 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3710 {\it flags
} should be a bitlist of one or more of the following values.
3715 wxUPDATE_UI_NONE =
0x0000, // No particular value
3716 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
3717 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
3721 If you are calling this function from an OnInternalIdle or OnIdle
3722 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
3723 this tells the window to only update the UI elements that need
3724 to be updated in idle time. Some windows update their elements
3725 only when necessary, for example when a menu is about to be shown.
3726 The following is an example of how to call UpdateWindowUI from
3730 void MyWindow::OnInternalIdle()
3732 if (wxUpdateUIEvent::CanUpdate(this))
3733 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);

}\label{wxwindowvalidate

3746 \func{virtual bool

3748 Validates the current values of the child controls using their validators.
3750 If the window has
{\tt wxWS
\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3751 the method will also call Validate() of all child windows.
3753 \wxheading{Return value

3755 Returns
{\tt false
} if any of the validations failed.
