\section{\class{wxAnimationCtrl}}\label{wxanimationctrl}

This is a static control which displays an animation.
wxAnimationCtrl API is simple as possible and won't give you full control on the
animation; if you need it then use \helpref{wxMediaCtrl}{wxmediactrl}.

This control is useful to display a (small) animation while doing a long task
(e.g. a "throbber").

It is only available if \texttt{wxUSE\_ANIMATIONCTRL} is set to $1$ (the default).

\membersection{wxAnimationCtrl::wxAnimationCtrl}\label{wxanimationctrl}

\func{}{wxAnimationCtrl}{\param{wxWindow *}{parent},\rtfsp
\param{wxWindowID}{ id},\rtfsp
\param{const wxAnimation\& }{anim},\rtfsp
\param{const wxPoint\& }{pos = wxDefaultPosition},\rtfsp
\param{const wxSize\& }{size = wxDefaultSize},\rtfsp
\param{long}{ style = wxAC\_DEFAULT\_STYLE},\rtfsp
\param{const wxString\& }{name = ``animationctrl"}}

Initializes the object and calls \helpref{Create}{wxanimationctrlcreate} with
all the parameters.


\membersection{wxAnimationCtrl::Create}\label{wxanimationctrlcreate}

\func{bool}{Create}{\param{wxWindow *}{parent},\rtfsp
\param{wxWindowID}{ id},\rtfsp
\param{const wxAnimation\& }{anim},\rtfsp
\param{const wxPoint\& }{pos = wxDefaultPosition},\rtfsp
\param{const wxSize\& }{size = wxDefaultSize},\rtfsp
\param{long}{ style = wxAC\_DEFAULT\_STYLE},\rtfsp
\param{const wxString\& }{name = ``animationctrl"}}

\wxheading{Parameters}

\docparam{parent}{Parent window, must be non-\NULL.}

\docparam{id}{The identifier for the control.}

\docparam{anim}{The initial animation shown in the control.}

\docparam{pos}{Initial position.}

\docparam{size}{Initial size.}

\docparam{style}{The window style, see {\tt wxAC\_*} flags.}

\docparam{name}{Control name.}

After control creation you must explicitely call \helpref{Play}{wxanimationctrlplay}
to start to play the animation. Until that function won't be called, the first frame
of the animation is displayed.

\wxheading{Return value}

\true if the control was successfully created or \false if creation failed.


\membersection{wxAnimationCtrl::GetAnimation}\label{wxanimationctrlgetanimation}

\constfunc{wxAnimation}{GetAnimation}{\void}

Returns the animation associated with this control.


\membersection{wxAnimationCtrl::GetInactiveBitmap}\label{wxanimationctrlgetinactivebitmap}

\constfunc{wxBitmap}{GetInactiveBitmap}{\void}

Returns the inactive bitmap shown in this control when the;
see \helpref{SetInactiveBitmap}{wxanimationctrlsetinactivebitmap} for more info.


\membersection{wxAnimationCtrl::IsPlaying}\label{wxanimationctrlisplaying}

\constfunc{bool}{IsPlaying}{\void}

Returns \true if the animation is being played.


\membersection{wxAnimationCtrl::LoadFile}\label{wxanimationctrlloadfile}

\func{bool}{LoadFile}{\param{const wxString \&}{ file}, \param{wxAnimationType }{ animType = wxANIMATION\_TYPE\_ANY}}

Loads the animation from the given file and calls \helpref{SetAnimation}{wxanimationctrlsetanimation}.
See \helpref{wxAnimation::LoadFile}{wxanimationloadfile} for more info.


\membersection{wxAnimationCtrl::Play}\label{wxanimationctrlplay}

\func{bool}{Play}{\void}

Starts playing the animation.
The animation is always played in loop mode (unless the last frame of the animation
has an infinite delay time) and always start from the first frame
(even if you \helpref{stopped}{wxanimationctrlstop} it while some other frame was
displayed).


\membersection{wxAnimationCtrl::SetAnimation}\label{wxanimationctrlsetanimation}

\func{void}{SetAnimation}{\param{const wxAnimation \&}{ anim}}

Sets the animation to play in this control.
If the previous animation is being played, it's \helpref{Stopped}{wxanimationctrlstop}.

Until \helpref{Play}{wxanimationctrlplay} isn't called, a static image, the first
frame of the given animation or the background colour will be shown
(see \helpref{SetInactiveBitmap}{wxanimationctrlsetinactivebitmap} for more info).


\membersection{wxAnimationCtrl::SetInactiveBitmap}\label{wxanimationctrlsetinactivebitmap}

\func{void}{SetInactiveBitmap}{\param{const wxBitmap\& }{bmp}}

Sets the bitmap to show on the control when it's not playing an animation.
If you set as inactive bitmap {\tt wxNullBitmap} (which is the default), then the
first frame of the animation is instead shown when the control is inactive; in this case,
if there's no valid animation associated with the control (see \helpref{SetAnimation}{wxanimationctrlsetanimation}),
then the background colour of the window is shown.

If the control is not playing the animation, the given bitmap will be immediately
shown, otherwise it will be shown as soon as \helpref{Stop}{wxanimationctrlstop}
is called.

Note that the inactive bitmap, if smaller than the control's size, will be centered in
the control; if bigger, it will be stretched to fit it.


\membersection{wxAnimationCtrl::Stop}\label{wxanimationctrlstop}

\func{void}{Stop}{\void}

Stops playing the animation.
The control will show the first frame of the animation, a custom static image or
the window's background colour as specified by the
last \helpref{SetInactiveBitmap}{wxanimationctrlsetinactivebitmap} call.
