NAME

       wxImageList - Functions for wxImageList class

DESCRIPTION

       A  wxImageList  contains a list of images, which are stored in an unspecified form. Images
       can have masks for transparent drawing,  and  can  be  made  from  a  variety  of  sources
       including bitmaps and icons.

       wxImageList is used principally in conjunction with wxTreeCtrl and wxListCtrl classes.

       See: wxTreeCtrl, wxListCtrl

       wxWidgets docs: wxImageList

DATA TYPES

       wxImageList() = wx:wx_object()

EXPORTS

       new() -> wxImageList()

              Default ctor.

       new(Width, Height) -> wxImageList()

              Types:

                 Width = Height = integer()

       new(Width, Height, Options :: [Option]) -> wxImageList()

              Types:

                 Width = Height = integer()
                 Option = {mask, boolean()} | {initialCount, integer()}

              Constructor  specifying  the image size, whether image masks should be created, and
              the initial size of the list.

              See: create/4

       add(This, Icon) -> integer()

              Types:

                 This = wxImageList()
                 Icon = wxIcon:wxIcon() | wxBitmap:wxBitmap()

              Adds a new image using an icon.

              Return: The new zero-based image index.

              Remark: The original bitmap or icon is not affected by the add/3 operation, and can
              be deleted afterwards. If the bitmap is wider than the images in the list, then the
              bitmap  will  automatically  be  split  into  smaller  images,  each  matching  the
              dimensions of the image list. This does not apply when adding icons.

              Only for:wxmsw,wxosx

       add(This, Bitmap, Mask) -> integer()

       add(This, Bitmap, MaskColour) -> integer()

              Types:

                 This = wxImageList()
                 Bitmap = wxBitmap:wxBitmap()
                 MaskColour = wx:wx_colour()

              Adds a new image or images using a bitmap and mask colour.

              Return: The new zero-based image index.

              Remark: The original bitmap or icon is not affected by the add/3 operation, and can
              be deleted afterwards. If the bitmap is wider than the images in the list, then the
              bitmap  will  automatically  be  split  into  smaller  images,  each  matching  the
              dimensions of the image list. This does not apply when adding icons.

       create(This, Width, Height) -> boolean()

              Types:

                 This = wxImageList()
                 Width = Height = integer()

       create(This, Width, Height, Options :: [Option]) -> boolean()

              Types:

                 This = wxImageList()
                 Width = Height = integer()
                 Option = {mask, boolean()} | {initialCount, integer()}

              Initializes the list.

              See new/3 for details.

       draw(This, Index, Dc, X, Y) -> boolean()

              Types:

                 This = wxImageList()
                 Index = integer()
                 Dc = wxDC:wxDC()
                 X = Y = integer()

       draw(This, Index, Dc, X, Y, Options :: [Option]) -> boolean()

              Types:

                 This = wxImageList()
                 Index = integer()
                 Dc = wxDC:wxDC()
                 X = Y = integer()
                 Option = {flags, integer()} | {solidBackground, boolean()}

              Draws a specified image onto a device context.

       getBitmap(This, Index) -> wxBitmap:wxBitmap()

              Types:

                 This = wxImageList()
                 Index = integer()

              Returns the bitmap corresponding to the given index.

       getIcon(This, Index) -> wxIcon:wxIcon()

              Types:

                 This = wxImageList()
                 Index = integer()

              Returns the icon corresponding to the given index.

       getImageCount(This) -> integer()

              Types:

                 This = wxImageList()

              Returns the number of images in the list.

       getSize(This, Index) -> Result

              Types:

                 This = wxImageList()
                 Index = integer()

              Retrieves the size of the images in the list.

              Currently, the index parameter is ignored as all images in the list have  the  same
              size.

              Return:  true  if  the  function succeeded, false if it failed (for example, if the
              image list was not yet initialized).

       remove(This, Index) -> boolean()

              Replaces the existing image with the new image.

              Return: true if the replacement was successful, false otherwise.

              Remark: The original bitmap or icon is not affected by the replace/4 operation, and
              can be deleted afterwards.

              Only for:wxmsw,wxosx

       replace(This, Index, Bitmap, Mask) -> boolean()
