The following styles can apply to all windows, although they will not always make sense for a particular
the window wants to get all char/key events for all keys - even for
keys like TAB or ENTER which are usually used for dialog navigation
and which wouldn't be generated without this style. If you need to
-use this style in order to get the arrows or etc., but would still like to have
-normal keyboard navigation take place, you should create and send a
-wxNavigationKeyEvent in response to the key events for Tab and
-Shift-Tab.}

+Tab and Shift-Tab.}
\twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{On Windows, this style used to disable repainting
the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete
and no longer has an effect.}
-\twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
-\twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
+\twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical
+scrollbar. Notice that this style cannot be used with native controls
+which don't support scrollbars nor with top-level windows in most ports.}
+\twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal
+scrollbar. The same limitations as for wxVSCROLL apply to this style.}
\twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
disable them instead of hiding them when they are not needed (i.e. when the
size of the window is big enough to not require the scrollbars to navigate it).

+\membersection{wxWindow::AcceptsFocus}\label{wxwindowacceptsfocus}
+
+\constfunc{bool}{AcceptsFocus}{\void}
+
+This method may be overridden in the derived classes to return \false to
+indicate that this control doesn't accept input at all (i.e. behaves like e.g.
+\helpref{wxStaticText}{wxstatictext}) and so doesn't need focus.

+
+\membersection{wxWindow::AcceptsFocusFromKeyboard}\label{wxwindowacceptsfocusfromkeyboard}
+
+\constfunc{bool}{AcceptsFocusFromKeyboard}{\void}
+
+This method may be overridden in the derived classes to return \false to
+indicate that while this control can, in principle, have focus if the user
+clicks it with the mouse, it shouldn't be included in the TAB traversal chain
+when using the keyboard.

\membersection{wxWindow::AddChild}\label{wxwindowaddchild}
\func{virtual void}{AddChild}{\param{wxWindow* }{child}}
\func{virtual void}{Fit}{\void}
Sizes the window so that it fits around its subwindows. This function won't do
-anything if there are no subwindows and will only really work correctly if the
+anything if there are no subwindows and will only really work correctly if
sizers are used for the subwindows layout. Also, if the window has exactly one
subwindow it is better (faster and the result is more precise as Fit adds some
margin to account for fuzziness of its calculations) to call
\constfunc{wxSize}{GetClientSize}{\void}
-This gets the size of the window `client area' in pixels.
-The client area is the area which may be drawn on by the programmer,
-excluding title bar, border, scrollbars, etc.
+Returns the size of the window `client area' in pixels. The client area is the
+area which may be drawn on by the programmer, excluding title bar, border,
+scrollbars, etc.
+
+Note that if this window is a top-level one and it is currently minimized, the
+return size is empty (both width and height are $0$).
\wxheading{Parameters}
\constfunc{virtual wxRect}{GetRect}{\void}
-Returns the size and position of the window as a \helpref{wxRect}{wxrect} object.
+Returns the position and size of the window as a \helpref{wxRect}{wxrect} object.

\constfunc{wxSize}{GetSize}{\void}
-This gets the size of the entire window in pixels,
-including title bar, border, scrollbars, etc.
+Returns the size of the entire window in pixels, including title bar, border,
+scrollbars, etc.
+
+Note that if this window is a top-level one and it is currently minimized, the
+returned size is the restored window size, not the size of the window icon.
\wxheading{Parameters}
\membersection{wxWindow::GetTextExtent}\label{wxwindowgettextextent}
-\constfunc{virtual void}{GetTextExtent}{\param{const wxString\& }{string}, \param{int* }{x}, \param{int* }{y},

\param{const wxFont* }{font = NULL}, \param{bool}{ use16 = {\tt false}}}
+\constfunc{wxSize}{GetTextExtent}{\param{const wxString\& }{string}}
+
Gets the dimensions of the string as it would be drawn on the
window with the currently selected font.
+The text extent is returned in \arg{w} and \arg{h} pointers (first form) or as a
+\helpref{wxSize}{wxsize} object (second form).
+
\wxheading{Parameters}
\docparam{string}{String whose extent is to be measured.}
-\docparam{x}{Return value for width.}
+\docparam{w}{Return value for width.}
-\docparam{y}{Return value for height.}
+\docparam{h}{Return value for height.}
\docparam{descent}{Return value for descent (optional).}
\helpref{wxMouseCaptureChangedEvent}{wxmousecapturechangedevent}
+\membersection{wxWindow::HasExtraStyle}\label{wxwindowhasextrastyle}
+
+\constfunc{bool}{HasExtraStyle}{\param{int }{exFlag}}
+
+Returns \texttt{true} if the window has the given \arg{exFlag} bit set in its
+extra styles.

\membersection{wxWindow::HasFlag}\label{wxwindowhasflag}
\constfunc{bool}{HasFlag}{\param{int }{flag}}
\constfunc{virtual bool}{IsEnabled}{\void}
-Returns {\tt true} if the window is enabled for input, {\tt false} otherwise.
+Returns \true if the window is enabled, i.e. if it accepts user input, \false
+otherwise.
+
+Notice that this method can return \false even if this window itself hadn't
+been explicitly disabled when one of its parent windows is disabled. To get the
+intrinsic status of this window, use
+\helpref{IsThisEnabled}{wxwindowisthisenabled}
\wxheading{See also}
\helpref{wxWindow::IsShown}{wxwindowisshown}
+\membersection{wxWindow::IsThisEnabled}\label{wxwindowisthisenabled}
+
+\constfunc{bool}{IsThisEnabled}{\void}
+
+Returns \true if this window is intrinsically enabled, \false otherwise, i.e.
+if \helpref{Enable(false)}{wxwindowenable} had been called. This method is
+mostly used for wxWidgets itself, user code should normally use
+\helpref{IsEnabled}{wxwindowisenabled} instead.
+
+
\membersection{wxWindow::IsTopLevel}\label{wxwindowistoplevel}
\constfunc{bool}{IsTopLevel}{\void}
\func{bool}{Navigate}{\param{int}{ flags = wxNavigationKeyEvent::IsForward}}
-Does keyboard navigation from this window to another, by sending
-a wxNavigationKeyEvent.
+Performs a keyboard navigation action starting from this window. This method is
+equivalent to calling \helpref{NavigateIn()}{wxwindownavigatein} method on the
+parent window.
\wxheading{Parameters}
\docparam{flags}{A combination of wxNavigationKeyEvent::IsForward and wxNavigationKeyEvent::WinChange.}
+\wxheading{Return value}
+
+Returns \true if the focus was moved to another window or \false if nothing
+changed.
+
\wxheading{Remarks}
You may wish to call this from a text control custom keypress handler to do the default
a multiline text control with the wxTE\_PROCESS\_TAB style is to insert a tab
and not navigate to the next control.
+
+\membersection{wxWindow::NavigateIn}\label{wxwindownavigatein}
+
+\func{bool}{NavigateIn}{\param{int}{ flags = wxNavigationKeyEvent::IsForward}}
+
+Performs a keyboard navigation action inside this window.
+
+See \helpref{Navigate}{wxwindownavigate} for more information.
+
+
+\membersection{wxWindow::NextControlId}\label{wxwindownextcontrolid}
+
+\func{static int}{NextControlId}{\param{int }{winid}}
+
+If two controls are created consecutively using \texttt{wxID\_ANY} id, this
+function allows to retrieve the effective id of the latter control from the id
+of the former. This is useful for example to find the control following its
+\helpref{wxStaticText}{wxstatictext} label if only the id of or pointer to the
+label is available to the caller but it is known that the two controls were
+created together.

%% VZ: wxWindow::OnXXX() functions should not be documented but I'm leaving

+\membersection{wxWindow::PrevControlId}\label{wxwindowprevcontrolid}
+
+\func{static int}{PrevControlId}{\param{int }{winid}}
+
+This is similar to \helpref{NextControlId}{wxwindownextcontrolid} but returns
+the id of the control created just before the one with the given \arg{winid}.
+
+

\membersection{wxWindow::SetFont}\label{wxwindowsetfont}
-\func{void}{SetFont}{\param{const wxFont\& }{font}}
+\func{bool}{SetFont}{\param{const wxFont\& }{font}}
Sets the font for this window. This function should not be called for the
parent window if you don't want its font to be inherited by its children,
\docparam{font}{Font to associate with this window, pass
{\tt wxNullFont} to reset to the default font.}

+\true if the want was really changed, \false if it was already set to this
+\arg{font} and so nothing was done.

the window's sizer. See below.}
-\docparam{deleteOld}{If true (the default), this will delete any prexisting sizer.
