## Constructor & Destructor Documentation

## ◆ wxAnimation() [1/3]

wxAnimation::wxAnimation | ( |  | ) |

Constructs a new empty animation object.

Call Load() to initialize it.

See also
  wxAnimationCtrl::CreateAnimation()

## ◆ wxAnimation() [2/3]

wxAnimation::wxAnimation | ( | const wxString & | name,
|  | wxAnimationType | type = `wxANIMATION_TYPE_ANY`
| ) |  |

Constructs a new animation object and load the animation data from the given filename.

Parameters

  name | A filename.
  type | One of the wxAnimationType values; wxANIMATION_TYPE_ANY means that the function should try to autodetect the filetype.

See also
  wxAnimationCtrl::CreateAnimation()

## ◆ wxAnimation() [3/3]

wxAnimation::wxAnimation | ( | const wxAnimation & | other | ) |

Copy constructor.

## Member Function Documentation

## ◆ AddHandler()

static void wxAnimation::AddHandler | ( | wxAnimationDecoder * | handler | ) |

static

Add a new decoder to the list of animation decoders.

## ◆ CleanUpHandlers()

static void wxAnimation::CleanUpHandlers | ( |  | ) |

static

Clear out the animation decoder list.

This is called automatically at program shutdown.

## ◆ FindHandler()

static const wxAnimationDecoder* wxAnimation::FindHandler | ( | wxAnimationType | animType | ) |

static

Search for an animation decoder by type.

## ◆ GetDelay()

int wxAnimation::GetDelay | ( | unsigned int | frame | ) | const

Returns the delay for the i-th frame in milliseconds.

If `-1` is returned the frame is to be displayed forever.

## ◆ GetFrame()

wxImage wxAnimation::GetFrame | ( | unsigned int | frame | ) | const

Returns the i-th frame as a wxImage.

This method is not implemented in the native wxGTK implementation of this class and always returns an invalid image there.

## ◆ GetFrameCount()

unsigned int wxAnimation::GetFrameCount | ( |  | ) | const

Returns the number of frames for this animation.

This method is not implemented in the native wxGTK implementation of this class and always returns 0 there.

## ◆ GetHandlers()

static wxAnimationDecoderList& wxAnimation::GetHandlers | ( |  | ) |

inline static

Returns the list of animation decoders used by the generic animation and `wxGenericAnimationCtrl`.

## ◆ GetSize()

wxSize wxAnimation::GetSize | ( |  | ) | const

Returns the size of the animation.

## ◆ InitStandardHandlers()

static void wxAnimation::InitStandardHandlers | ( |  | ) |

static

Load the stock animation decoders (currently GIF and ANI) into the list of decoders.

This is called automatically at program startup.

## ◆ InsertHandler()

static void wxAnimation::InsertHandler | ( | wxAnimationDecoder * | handler | ) |

static

Insert a new decoder to the front of the list of animation decoders.

## ◆ IsCompatibleWith()

bool wxAnimation::IsCompatibleWith | ( | wxClassInfo * | ci | ) | const

Returns true if animation can be used with controls of the given type.

This function checks if this animation object can be used with wxAnimationCtrl of particular type. This will be always the case for the platforms where only a single wxAnimationCtrl implementation is available, but not necessarily under e.g. wxGTK where both native (but limited) GTK implementation and generic implementation can be used.

Since
  3.1.4

## ◆ IsOk()

bool wxAnimation::IsOk | ( |  | ) | const

Returns true if animation data is present.

## ◆ Load()

bool wxAnimation::Load | ( | wxInputStream & | stream,
|  | wxAnimationType | type = `wxANIMATION_TYPE_ANY`
| ) |  |

Loads an animation from the given stream.

Parameters

  stream | The stream to use to load the animation. Under wxGTK may be any kind of stream; under other platforms this must be a seekable stream.
  type | One of the wxAnimationType enumeration values.

Returns
  true if the operation succeeded, false otherwise.

## ◆ LoadFile()

bool wxAnimation::LoadFile | ( | const wxString & | name,
|  | wxAnimationType | type = `wxANIMATION_TYPE_ANY`
| ) |  |

Loads an animation from a file.

Parameters

  name | A filename.
  type | One of the wxAnimationType values; wxANIMATION_TYPE_ANY means that the function should try to autodetect the filetype.

Returns
  true if the operation succeeded, false otherwise.
