Estimating the term…
A system and method are disclosed whereby two components within the Swing application program interface (API), JTextField and JPasswordField, are used to emulate the behavior of the TextField component in the abstract windowing toolkit (AWT). This allows legacy Java applications, based on the AWT, to be migrated to the platform-independent Swing API, without modification. In the AWT, a single TextField component could be used for ordinary text entry, as well as for password protected text entry. In the latter case, a prescribed echo character would be displayed as text was entered, to avoid displaying privileged information. According to the system and method disclosed herein, a JPasswordField component may be substituted for a JTextField component, or vice-versa, depending on whether an echo character has been specified. This substitution is performed at runtime, using an enhanced version of the Swing API, as disclosed herein. The enhanced version of Swing is referred to herein as AWTSwing.
A system of software components stored on a computer-readable medium adapted to display an object created by an application program running under an operating system by reproducing the behavior of legacy AWT-based controls by switching between swing controls, wherein the system of software components comprises:
A method for displaying an object created by an application program running under an operating system, by reproducing the behavior of legacy AWT-based controls by switching between swing controls, using at least one of a system of software components stored on a computer-readable medium, which can be invoked during runtime to generate a graphical representation of the object that is substantially independent of the operating system, the method performed by the application program and comprising:
A computer-readable storage device, comprising:
