TCustomImageList.Initialize procedure

Declaration

procedure Initialize; virtual

Description

Initialize is a procedure used to perform the in ital set up for the image list. Initialize creates the internal TCustomImageListResolutions class instance used to store image resolutions in the image list. The internal list used for TChangeLink notifications is also created. The internal allocation block count is set to 4.

Initialize sets the default values for the following properties:

clNone

BkColor

clNone

DrawingStyle

The ClearOverlays method is called to reset any images assigned as overlay images in the image list.

Initialize is used in the Create and CreateSize constructors. Create sets the default values for the Height and Width properties to 16. CreateSize uses the arguments passed to the constructor as the value for the properties.

Errors

Initialize raises an EInvalidOperation exception if the value in the Height or Width property is invalid. Height must be in the range 1..32768, and Width must be a positive non-zero Integer value. Raised with the message in SInvalidImageSize.
