wxImageList

^{generated from ../src/mod_gui/misc/imagelst.cpp}

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.

Constants

Constructor

wxImageList

wxImageList()
 

wxImageList(Width, 
            Height, 
            Mask = true, 
            Count = 1)
 

Name	Type	Default	Description
Width	Integer		The width of the images in the list
Height	Integer		The height of the images in the list.
Mask	Boolean	true	When true (default) a mask is created for each image.
Count	Integer	1	The size of the list.

Constructs a new wxImageList object.

Properties

Name	Type	Description
imageCount	Integer	Returns the number of the images.

Methods

add

add(Bitmap, 
    Mask) : Integer
 

Name	Type	Default	Description
Bitmap	wxBitmap
Mask	Integer

add(Bitmap, 
    Colour) : Integer
 

Name	Type	Default	Description
Bitmap	wxBitmap
Colour	wxColour

add(Icon) : Integer
 

Name	Type	Default	Description
Icon	wxIcon

Adds a new image using a bitmap and an optional mask bitmap or adds a new image using a bitmap and a mask colour or adds a new image using an icon. Returns the new zero-based index of the image.

create

create(Width, 
       Height, 
       Mask = true, 
       Count = 1)
 

Name	Type	Default	Description
Width	Integer		The width of the images in the list
Height	Integer		The height of the images in the list.
Mask	Boolean	true	When true (default) a mask is created for each image.
Count	Integer	1	The size of the list.

Creates an image list. Width and Height specify the size of the images in the list (all the same). Mask specifies whether the images have masks or not. Count is the initial number of images to reserve.

getSize

getSize(Index, 
        Size) : Boolean
 

Name	Type	Default	Description
Index	Integer		The index parameter is ignored as all images in the list have the same size.
Size	wxSize		Receives the size of the image.

The size is put in the Size argument. This method differs from the wxWindow function GetSize which uses 3 arguments: index, width and height. wxJS uses wxSize because JavaScript can't pass primitive types by reference.

remove

remove(Index) : Boolean
 

Name	Type	Default	Description
Index	Integer		The index of the image.

Removes the image with the given index. Returns true on success.

removeAll

removeAll() : Boolean
 

Removes all images. Returns true on success.

replace

replace(Index, 
        Bitmap, 
        Mask) : Boolean
 

Name	Type	Default	Description
Index	Integer		The index of the image to replace.
Bitmap	wxBitmap		The new bitmap.
Mask	wxBitmap		Monochrome mask bitmap, representing the transparent areas of the image. Windows only.

replace(Index, 
        Icon) : Boolean
 

Name	Type	Default	Description
Index	Integer		The index of the image to replace.
Icon	wxIcon		Icon to use as image.

Replaces the image at the given index with a new image.
