Java Source File NameTypeComment
Color.javaClass Instances of this class manage the operating system resources that implement SWT's RGB color model.
Cursor.javaClass Instances of this class manage operating system resources that specify the appearance of the on-screen pointer.
Device.javaClass This class is the abstract superclass of all device objects, such as the Display device and the Printer device.
DeviceData.javaClass
Drawable.javaInterface Implementers of Drawable can have a graphics context (GC) created for them, and then they can be drawn on by sending messages to their associated GC.
Font.javaClass Instances of this class manage operating system resources that define how text looks when it is displayed.
FontData.javaClass Instances of this class describe operating system fonts.
FontMetrics.javaClass Instances of this class provide measurement information about fonts including ascent, descent, height, leading space between rows, and average character width.
GC.javaClass Class GC is where all of the drawing capabilities that are supported by SWT are located.
GCData.javaClass Instances of this class are descriptions of GCs in terms of unallocated platform-specific data fields.

IMPORTANT: This class is not part of the public API for SWT.

Image.javaClass Instances of this class are graphics which have been prepared for display on a specific device.
ImageData.javaClass Instances of this class are device-independent descriptions of images.
ImageDataLoader.javaClass
ImageLoader.javaClass Instances of this class are used to load images from, and save images to, a file or stream.
ImageLoaderEvent.javaClass Instances of this class are sent as a result of the incremental loading of image data.

Notes:

  • The number of events which will be sent when loading images is not constant.
ImageLoaderListener.javaInterface Classes which implement this interface provide methods that deal with the incremental loading of image data.
PaletteData.javaClass Instances of this class describe the color data used by an image.

Depending on the depth of the image, the PaletteData can take one of two forms, indicated by the isDirect field:

isDirect is false
If isDirect is false, this palette is an indexed palette which maps pixel values to RGBs.
Path.javaClass Instances of this class represent paths through the two-dimensional coordinate system.
PathData.javaClass Instances of this class describe device-independent paths.
Pattern.javaClass Instances of this class represent patterns to use while drawing.
Point.javaClass Instances of this class represent places on the (x, y) coordinate plane.

The coordinate space for rectangles and points is considered to have increasing values downward and to the right from its origin making this the normal, computer graphics oriented notion of (x, y) coordinates rather than the strict mathematical one.

The hashCode() method in this class uses the values of the public fields to compute the hash value.

Rectangle.javaClass Instances of this class represent rectangular areas in an (x, y) coordinate system.
Region.javaClass Instances of this class represent areas of an x-y coordinate system that are aggregates of the areas covered by a number of polygons.
Resource.javaClass This class is the abstract superclass of all graphics resource objects.
RGB.javaClass Instances of this class are descriptions of colors in terms of the primary additive color model (red, green and blue).
TextLayout.javaClass TextLayout is a graphic object that represents styled text.

Instances of this class provide support for drawing, cursor navigation, hit testing, text wrapping, alignment, tab expansion line breaking, etc.

TextStyle.javaClass TextStyle defines a set of styles that can be applied to a range of text.

The hashCode() method in this class uses the values of the public fields to compute the hash value.

Transform.javaClass Instances of this class represent transformation matrices for points expressed as (x, y) pairs of floating point numbers.
