Introduction of GLG

GLG developed by Generic Logic, Inc.

GLG Toolkit is used to create UI or simulator

Various development environments
Introduction of GLG

GLG consists of
 GLG Graphics Builder
 A set of GLG containers
 (GLG Bean, GLG Wrapper Widget, GLG ActiveX Control, etc)
 Many function(called API) can use
GLG Toolkit
GLG Programming for Java

GLG Toolkit provides a 100% Java class
library
 GlgBean : AWT-based Java bean and applet
(subclass from Applet)
 GlgJBean : Swing-based Java bean and applet
(subclass from JApplet)
 GlgJLWBean : Swing-based Java bean
(for use with JDesktopPane and JInternalFrame)

Toolkit provides GLG jar files containing the
com.genlogic package
GLG Programming for Java

Adding GlgBean to an Application Interface
 As a Java bean component in a stand-alone Java application
 As a top level applet
 - Using GlgBean as an Applet
 As a Java bean component inside another applet
 Using GlgBean as a Component of an Applet
GLG Programming for Java

Loading and Displaying a Drawing
 SetDrawingURL(drawing_url);
 SetDrawingFile(filename);
 SetDrawingName(drawing_name);

GlgBean provides the SetParentApplet method
GLG Programming for Java

Initializing the Drawing

Listener of the GlgBean, GlgJBean, GlgJLWBean
 GlgReadyListener interface : invoked after the drawing is ready
 GlgHListener interface :invoked upon hierarchy setup, after the
drawing is loaded
 GlgVListener interface : invoked after the drawing is loaded
and after the hierarchy setup has
occurred
 GlgReadyListener - public void ReadyCallback(GlgObject viewport);
 GlgHListener – public void HCallback(GlgObject viewport);
 GlgVListener – public void Vcallback(GlgObject viewport);


Handling user interaction
Listener of the GlgBean, GlgJBean, GlgJLWBean
 GlgInputListener : invoked upon any interaction with the
GLG objects
 GlgSelectListener : invoked when a named GLG object is
selected with the mouse
 GlgTraceListener : invoked mouse clicks and mouse motion
 GlgInputListener – public void InputCallback(GlgObject viewport,
GlgObject message_obj);
 GlgSelectListener – public void SelectCallback(GlgObject viewport,
Object[] name_array, int
button);
 GlgTraceListener – public void TraceCallback(GlgObject viewport,
GlgTraceData trace_info);
GLG Programming for Java

Resource of message_obj
 Format – Defines the format of the input handler which
triggered the event.
 (Button, Slider, Knob, CustomEvent, ObjectSelection, etc)
 Origin – Contains the name of the viewport the event occurred
in or the name of the selected object
 FullOrigin – Full pathname of the viewport
 Action – Describes the occurred action. Action values depend
on the Format
 (ValueChanged, Activate, MouseClick, MouseOver, etc)
 Subaction – additional information about the event.
GLG Programming for Java

Handling Dynamic Updates
 SetDResource() : to set a double type resource
 SetSResource() : to set a string type resource
 SetGResource() : to set a geometric type resource
(Such as FillColor, EdgeColor, etc)
 Update() : to reflect new resource values.
