}}\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.

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

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

234 and when the mouse is released the capture returns to the window which had had

236 window. In particular, this means that you must release the mouse as many times
237 as you capture it, unless the window receives
238 the

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

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

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

864 \func{static wxVisualAttributes
}{GetClassDefaultAttributes
}{\param{wxWindowVariant

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

}{wxwindowgetclassdefaultattributes
}(
\helpref{GetWindowVariant

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

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

3213 Let's say you wish to display
50 lines of text, using the same font.
3214 The window is sized so that you can only see
16 lines at a time.
3220 SetScrollbar(wxVERTICAL,
0,
16,
50);
3224 Note that with the window at this size, the thumb position can never go
3225 above
50 minus
16, or
34.
3227 You can determine how many lines are currently visible by dividing the current view
3228 size by the character height in pixels.
3230 When defining your own scrollbar behaviour, you will always need to recalculate
3231 the scrollbar settings when the window size changes. You could therefore put your
3232 scrollbar calculations and SetScrollbar
3233 call into a function named AdjustScrollbars, which can be called initially and also

3261 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3262 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3263 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3264 value has to be adjusted when the window is resized, since the page size will have changed.
3266 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3267 the thumb changes size to reflect the page size relative to the length of the
document. When the
3268 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3269 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

3329 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3330 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3331 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3332 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3333 and usually the scrollbar will be automatically hidden.

3723 \func{virtual void
}{Update
}{\void}
3725 Calling this method immediately repaints the invalidated area of the window and
3726 all of its children recursively while this would usually only happen when the
3727 flow of control returns to the event loop.
3728 Notice that this function doesn't invalidate any area of the window so
3729 nothing happens if nothing has been invalidated (i.e. marked as requiring
3730 a redraw). Use
\helpref{Refresh
}{wxwindowrefresh
} first if you want to
3731 immediately redraw the window unconditionally.

}\label{wxwindowupdatewindowui
}
3736 \func{virtual void
}{UpdateWindowUI
}{\param{long
}{ flags = wxUPDATE
\_UI\_NONE}}
3738 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
3739 the window. The particular implementation depends on the window; for
3740 example a wxToolBar will send an update UI event for each toolbar button,
3741 and a wxFrame will send an update UI event for each menubar menu item.
3742 You can call this function from your application to ensure that your
3743 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3744 are concerned). This may be necessary if you have called
3745 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
3746 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval
} to
3747 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3749 {\it flags
} should be a bitlist of one or more of the following values.
3754 wxUPDATE_UI_NONE =
0x0000, // No particular value
3755 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
3756 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
3760 If you are calling this function from an OnInternalIdle or OnIdle
3761 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
3762 this tells the window to only update the UI elements that need
3763 to be updated in idle time. Some windows update their elements
3764 only when necessary, for example when a menu is about to be shown.
3765 The following is an example of how to call UpdateWindowUI from
3769 void MyWindow::OnInternalIdle()
3771 if (wxUpdateUIEvent::CanUpdate(this))
3772 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);

3790 the method will also call Validate() of all child windows.
