The image cell class
Copyright: (C) 1999, 2005 Free Software Foundation, Inc.
- Declared in:
- AppKit/NSImageCell.h
Availability: OpenStep
An NSImageCell is a cell that can display a single
image. It is normally associated with an NSImageView
control; but you can use it as a building block in
your own controls.
The image to display is set using the
-setImage:
method which is inherited from the superclass.
The
-setImageAlignment:
and
-setImageScaling:
methods can be used to control how the image is
drawn inside a rectangle which is larger or smaller
than the image size; the image might need to be
scaled, cropped or aligned.
The
-setImageFrameStyle:
method can be used to control if the cell should
display a frame border, and which one.
