NAME
wxImageList - Functions for wxImageList class
DESCRIPTION
A wxImageList contains a list of images, which are stored in an unspec-
ified 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:
Result =
{Res :: boolean(), Width :: integer(), Height :: inte-
ger()}
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()
Types:
This = wxImageList()
Index = integer()
Removes the image at the given position.
removeAll(This) -> boolean()
Types:
This = wxImageList()
Removes all the images in the list.
replace(This, Index, Icon) -> boolean()
Types:
This = wxImageList()
Index = integer()
Icon = wxIcon:wxIcon() | wxBitmap:wxBitmap()
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()
Types:
This = wxImageList()
Index = integer()
Bitmap = Mask = wxBitmap:wxBitmap()
Replaces the existing image with the new image.
Windows only.
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.
destroy(This :: wxImageList()) -> ok
Destroys the object.
