Several of the classes in package icsbep.graph.sgt.swing.prop are subclasses of JDialog. These classes group various Java components and manage their associated events and interactions. Several methods commonly appear in these subclasses. These methods are:

• applyButton_actionPerformed is invoked when the user clicks on the "Apply" button. This method invokes method updateXXXX where XXXX is the associated attribute, such as ContourLineAttribute.
• addNotify records the size of the window and adjusts the components according to the insets.
• cancelButton_actionPerformed is invoked when the user clicks on the "Cancel" button. This method cancels the operation and exits the dialog box.
• colorEditor_actionPerformed is invoked when the user clicks on the "Color Editor" button. This method updates the color with the entered red, green, and blue values.
• fontEditor_actionPerformed is invoked when the user clicks on the "Font editor" button. This method instantiates a FontDialog object and handles the actions in the "Font Editor" dialog.
• fontString converts and returns the given font as a String.
• getXXXX returns field XXXX where XXXX denotes a field in the dialog class.
• jbInit initializes all the components in the dialog box.
• labelColorEditor_actionPerformed is invoked when the user clicks on the "Label Color" button. This method updates the label color with the red, green, and blue values.
• okButton_actionPerformed is invoked when the user clicks on the "OK" button. This method invokes method update or updateXXXX where XXXX is the attribute object. The method then closes the dialog box.
• setXXXX where XXXX denotes a field in the dialog class. This method sets field XXXX to the given value.
• setVisible makes the dialog visible.
• showDialog shows the dialog for editing the specified object and waits for a response.
