Description
TCustomImageListResolutions is a class used to implement support
for multiple image sizes (or resolutions) in
TCustomImageList.
TCustomImageListResolutions maintains an internal list with
TCustomImageListResolution class instances representing each of
the image sizes (and the raw image data for the size) available in the
TCustomImageList instance. In essence, it allows TCustomImageList to treat
each image resolution as a distinct parallel image list.
The ImageLists property provides access to the image list for a
specific image width (or resolution), and performs image scaling when needed.
New image resolutions are dynamically created and added to the container when
a size is requested that is not already present.
Use the Items property to access the TCustomImageListResolution
class instances stored in the container. Use the Count property to
determine the number of image resolutions stored in the container. Use the
Clear and Delete methods to maintain image resolutions
in the container.
TCustomImageListResolutions is used in the implementation of TCustomImageList.
