}}\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, wxWindows 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, wxWindows 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.

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

}
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.

309 This function simply generates a

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

351 Converts a point or size from dialog units to pixels.
353 For the x dimension, the dialog units are multiplied by the average character width
354 and then divided by
4.
356 For the y dimension, the dialog units are multiplied by the average character height
357 and then divided by
8.
361 Dialog units are used for maintaining a dialog's proportions even if the font changes.
363 You can also use these functions programmatically. A convenience macro is defined:

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

2464 Let's say you wish to display
50 lines of text, using the same font.
2465 The window is sized so that you can only see
16 lines at a time.
2471 SetScrollbar(wxVERTICAL,
0,
16,
50);
2475 Note that with the window at this size, the thumb position can never go
2476 above
50 minus
16, or
34.
2478 You can determine how many lines are currently visible by dividing the current view
2479 size by the character height in pixels.
2481 When defining your own scrollbar behaviour, you will always need to recalculate
2482 the scrollbar settings when the window size changes. You could therefore put your
2483 scrollbar calculations and SetScrollbar
2484 call into a function named AdjustScrollbars, which can be called initially and also
2485 from your

2510 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2511 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2512 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2513 value has to be adjusted when the window is resized, since the page size will have changed.
2515 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2516 the thumb changes size to reflect the page size relative to the length of the
document. When the
2517 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2518 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

2576 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2577 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2578 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2579 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2580 and usually the scrollbar will be automatically hidden.

2924 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
2925 the window. The particular implementation depends on the window; for
2926 example a wxToolBar will send an update UI event for each toolbar button,
2927 and a wxFrame will send an update UI event for each menubar menu item.
2928 You can call this function from your application to ensure that your
2929 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
2930 are concerned). This may be necessary if you have called
2931 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
2932 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval
} to
2933 limit the overhead that wxWindows incurs by sending update UI events in idle time.
2935 {\it flags
} should be a bitlist of one or more of the following values.
2940 wxUPDATE_UI_NONE =
0x0000, // No particular value
2941 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
2942 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
2946 If you are calling this function from an OnInternalIdle or OnIdle
2947 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
2948 this tells the window to only update the UI elements that need
2949 to be updated in idle time. Some windows update their elements
2950 only when necessary, for example when a menu is about to be shown.
