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

35 The following styles can apply to all windows, although they will not always make sense for a particular
36 window class or on all platforms.
39 \begin{twocollist

40 \twocolitem{\windowstyle{wxSIMPLE
\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
42 \twocolitem{\windowstyle{wxDOUBLE

\_BORDER}}{Displays a sunken border.
}
44 \twocolitem{\windowstyle{wxRAISED

}
45 \twocolitem{\windowstyle{wxSTATIC
\_BORDER}}{Displays a border suitable for a static control. Windows only.
}
46 \twocolitem{\windowstyle{wxNO
\_BORDER}}{Displays no border, overriding the default border style for the window.
}
47 \twocolitem{\windowstyle{wxTRANSPARENT
\_WINDOW}}{The window is transparent, that is, it will not receive paint
48 events. Windows only.
}
49 \twocolitem{\windowstyle{wxTAB
\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.
}
50 \twocolitem{\windowstyle{wxWANTS
\_CHARS}}{Use this to indicate that
51 the window wants to get all char/key events for all keys - even for
52 keys like TAB or ENTER which are usually used for dialog navigation
53 and which wouldn't be generated without this style. If you need to
54 use this style in order to get the arrows or etc., but would still like to have
55 normal keyboard navigation take place, you should create and send a
56 wxNavigationKeyEvent in response to the key events for Tab and
58 \twocolitem{\windowstyle{wxNO
\_FULL\_REPAINT\_ON\_RESIZE}}{Disables repainting
59 the window completely when its size is changed - you will have to repaint the

}
63 \twocolitem{\windowstyle{wxHSCROLL

64 \twocolitem{\windowstyle{wxALWAYS
\_SHOW\_SB}}{If a window has scrollbars,
65 disable them instead of hiding them when they are not needed (i.e. when the
66 size of the window is big enough to not require the scrollbars to navigate it).
67 This style is currently only implemented for wxMSW and wxUniversal and does
68 nothing on the other platforms.
}
69 \twocolitem{\windowstyle{wxCLIP
\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
70 repainted, then children being painted over them. Windows only.
}
71 \twocolitem{\windowstyle{wxFULL
\_REPAINT\_ON\_RESIZE}}{Use this style to force
72 a complete redraw of the window whenever it is resized instead of redrawing
73 just the part of the window affected by resizing. Note that this was the
74 behaviour by default before
2.5.1 release and that if you experience redraw
75 problems with the code which previously used to work you may want to try this.

322 This function simply generates a

323 handler usually tries to close the window. It doesn't close the window itself,
326 \wxheading{Parameters
}
328 \docparam{force
}{{\tt false
} if the window's close handler should be able to veto the destruction
329 of this window,
{\tt true
} if it cannot.
}
333 Close calls the
\helpref{close handler
}{wxcloseevent
} for the window, providing
334 an opportunity for the window to choose whether to destroy the window.
335 Usually it is only used with the top level windows (wxFrame and wxDialog
336 classes) as the others are not supposed to have any special OnClose() logic.
338 The close handler should check whether the window is being deleted forcibly,
339 using
\helpref{wxCloseEvent::GetForce
}{wxcloseeventgetforce
}, in which case it
340 should destroy the window using
\helpref{wxWindow::Destroy
}{wxwindowdestroy
}.
342 {\it Note
} that calling Close does not guarantee that the window will be
343 destroyed; but it provides a way to simulate a manual close of a window, which
344 may or may not be implemented by destroying the window. The default
345 implementation of wxDialog::OnCloseWindow does not necessarily delete the
346 dialog, since it will simply simulate an wxID
\_CANCEL event which is handled by
347 the appropriate button event handler and may do anything at all.

363 \func{wxSize

365 Converts a point or size from dialog units to pixels.
367 For the x dimension, the dialog units are multiplied by the average character width
368 and then divided by
4.
370 For the y dimension, the dialog units are multiplied by the average character height
371 and then divided by
8.
375 Dialog units are used for maintaining a dialog's proportions even if the font changes.
377 You can also use these functions programmatically. A convenience macro is defined:

626 sizers are used for the subwindows layout. Also, if the window has exactly one
627 subwindow it is better (faster and the result is more precise as Fit adds some
628 margin to account for fuzziness of its calculations) to call
631 window->SetClientSize(child->GetSize());
634 instead of calling Fit.

684 This method is similar to

685 in one thing. GetBestSize should return the minimum untruncated size of the
686 window, while this method will return the largest of BestSize and any user
687 specified minimum size. ie. it is the minimum size the window should currently
688 be drawn at, not the minimal size it can possibly tolerate.

709 example, for a static control, it will be the minimal size such that the
710 control label is not truncated. For windows containing subwindows (typically
711 \helpref{wxPanel

}
760 \func{static wxVisualAttributes
}{GetClassDefaultAttributes
}{\param{wxWindowVariant
}{ variant =
\texttt{wxWINDOW
\_VARIANT\_NORMAL}}}
762 Returns the default font and colours which are used by the control. This is
763 useful if you want to use the same font or colour in your own control as in a
764 standard control -- which is a much better idea than hard coding specific
765 colours or fonts which might look completely out of place on the users
766 system, especially if it uses themes.
768 The
\arg{variant
} parameter is only relevant under Mac currently and is
769 ignore under other platforms. Under Mac, it will change the size of the
770 returned font. See
\helpref{wxWindow::SetWindowVariant
}{wxwindowsetwindowvariant
}
773 This static method is ``overridden'' in many derived classes and so calling,
774 for example,
\helpref{wxButton
}{wxbutton
}::GetClassDefaultAttributes() will typically
775 return the values appropriate for a button which will be normally different
776 from those returned by, say,
\helpref{wxListCtrl
}{wxlistctrl
}::GetClassDefaultAttributes().
778 The
\texttt{wxVisualAttributes
} structure has at least the fields
779 \texttt{font
},
\texttt{colFg
} and
\texttt{colBg
}. All of them may be invalid
780 if it was not possible to determine the default control appearance or,
781 especially for the background colour, if the field doesn't make sense as is
782 the case for
\texttt{colBg
} for the controls with themed background.

854 \helpref{GetClassDefaultAttributes
}{wxwindowgetclassdefaultattributes
}(
\helpref{GetWindowVariant
}{wxwindowgetwindowvariant

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

1294 are used and in this case, nothing should be inherited as in modern GUIs
1295 different controls use different fonts (and colours) than their siblings so
1296 they can't inherit the same value from the parent. However it was also deemed
1297 desirable to allow to simply change the attributes of all children at once by
1298 just changing the font or colour of their common parent, hence in this case we
1299 do inherit the parents attributes.

2752 Let's say you wish to display

2753 The window is sized so that you can only see
16 lines at a time.
2759 SetScrollbar(wxVERTICAL,
0,
16,
50);
2763 Note that with the window at this size, the thumb position can never go

50 minus
16, or

2766 You can determine how many lines are currently visible by dividing the current view
2767 size by the character height in pixels.
2769 When defining your own scrollbar behaviour, you will always need to recalculate
2770 the scrollbar settings when the window size changes. You could therefore put your

2799 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2800 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2801 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2802 value has to be adjusted when the window is resized, since the page size will have changed.
2804 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2805 the thumb changes size to reflect the page size relative to the length of the
document. When the
2806 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2807 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

2867 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2868 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2869 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2870 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2871 and usually the scrollbar will be automatically hidden.

3148 \func{void
}{SetWindowVariant
}{\param{wxWindowVariant
}{variant
}}
3150 This function can be called under all platforms but only does anything under
3151 Mac OS X
10.3+ currently. Under this system, each of the standard control can
3152 exist in several sizes which correpond to the elements of wxWindowVariant
3155 enum wxWindowVariant
3157 wxWINDOW_VARIANT_NORMAL, // Normal size
3158 wxWINDOW_VARIANT_SMALL, // Smaller size (about
25 % smaller than normal )
3159 wxWINDOW_VARIANT_MINI, // Mini size (about
33 % smaller than normal )
3160 wxWINDOW_VARIANT_LARGE, // Large size (about
25 % larger than normal )
3164 By default the controls use the normal size, of course, but this function can
3165 be used to change this.

3180 \membersection{wxWindow::Show
}\label{wxwindowshow
}
3182 \func{virtual bool
}{Show
}{\param{bool

3184 Shows or hides the window. You may need to call
\helpref{Raise
}{wxwindowraise
}
3185 for a top level window if you want to bring it to top, although this is not
3186 needed if Show() is called immediately after the frame creation.

}
3192 \wxheading{Return value

3270 \membersection{wxWindow::Update
}\label{wxwindowupdate
}
3272 \func{virtual void
}{Update
}{\void}
3274 Calling this method immediately repaints the invalidated area of the window
3275 while this would usually only happen when the flow of control returns to the
3276 event loop. Notice that this function doesn't refresh the window and does
3277 nothing if the window hadn't been already repainted. Use
3278 \helpref{Refresh
}{wxwindowrefresh
} first if you want to immediately redraw the
3279 window unconditionally.
3282 \membersection{wxWindow::UpdateWindowUI
}\label{wxwindowupdatewindowui
}
3284 \func{virtual void
}{UpdateWindowUI
}{\param{long
}{ flags = wxUPDATE
\_UI\_NONE}}
3286 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
3287 the window. The particular implementation depends on the window; for
3288 example a wxToolBar will send an update UI event for each toolbar button,
3289 and a wxFrame will send an update UI event for each menubar menu item.
3290 You can call this function from your application to ensure that your
3291 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3292 are concerned). This may be necessary if you have called
3293 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
3294 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval
} to
3295 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3297 {\it flags
} should be a bitlist of one or more of the following values.
3302 wxUPDATE_UI_NONE =
0x0000, // No particular value
3303 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
3304 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
3308 If you are calling this function from an OnInternalIdle or OnIdle
3309 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
3310 this tells the window to only update the UI elements that need
3311 to be updated in idle time. Some windows update their elements
3312 only when necessary, for example when a menu is about to be shown.
3313 The following is an example of how to call UpdateWindowUI from
3317 void MyWindow::OnInternalIdle()
3319 if (wxUpdateUIEvent::CanUpdate(this))
3320 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);

3335 Validates the current values of the child controls using their validators.
3337 If the window has
{\tt wxWS
\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3338 the method will also call Validate() of all child windows.
3340 \wxheading{Return value

3342 Returns
