}}\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. wxSIMPLE
\_BORDER is the old name
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
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.

113 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
116 be used with transient windows as otherwise there is the risk of creating a

118 parent is destroyed before the child.

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

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

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

382 handler usually tries to close the window. It doesn't close the window itself,
385 \wxheading{Parameters
}
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.
}
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.
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
}.
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.
408 To guarantee that the window will be destroyed, call

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

866 \func{static wxVisualAttributes

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

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

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

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

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.
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

}{\void}
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.
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
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.

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.
3222 SetScrollbar(wxVERTICAL,
0,
16,
50);
3226 Note that with the window at this size, the thumb position can never go
3227 above
50 minus
16, or
34.
3229 You can determine how many lines are currently visible by dividing the current view
3230 size by the character height in pixels.
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

3235 call into a function named AdjustScrollbars, which can be called initially and also

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.
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)

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.

3725 \func{virtual void
}{Update
}{\void}
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.

}\label{wxwindowupdatewindowui
}
3738 \func{virtual void
}{UpdateWindowUI
}{\param{long
}{ flags = wxUPDATE
\_UI\_NONE}}
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.
3751 {\it flags
} should be a bitlist of one or more of the following values.
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
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
3771 void MyWindow::OnInternalIdle()
3773 if (wxUpdateUIEvent::CanUpdate(this))
3774 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
