Constructor Detail

JWFrame

public JWFrame()

Creates simple window with OK button. Uses the default colour schemes for the window. Includes icon if one exists (called Icon16.gif).

JWFrame

public JWFrame(String winTitle)

Creates simple window with title, and OK button. Uses the default colour schemes for the window. Includes icon if one exists (called Icon16.gif).

Parameters:

winTitle - Title placed on window bar.

JWFrame

public JWFrame(String winTitle,
               String mainTitle)

Creates simple window with titles, and OK button. Uses the default colour schemes for the window. Includes icon if one exists (called Icon16.gif).

Parameters:

winTitle - Title placed on window bar.

mainTitle - Main title displayed in dialogue window.

Method Detail

getGBConstraints

public GridBagConstraints getGBConstraints()

Retrieves the default GridBag layout constraints associated with this frame. Default assumes

• fill - fill horizontal space (HORIZONTAL)
• gridwidth - last on line (REMAINDER)
• anchor - top left of window (NORTHWEST)
• ipadx - 4 pixels
• ipady - 4 pixels
• weightx - 0.5
• weighty - 0.5

Returns:

Default GridBagConstraints.

getGBLayout

public GridBagLayout getGBLayout()

Retrieves current GridBagLayout (needed to add new componets to the frame.

Returns:

Current GridBagLayout.

add

public Component add(Component c)

Adds a component to the frame above the OK button if it is defined.

Overrides:

add in class Container

Returns:

Component added.

addReturnButtons

public void addReturnButtons()

Adds the return button to this frame.

actionPerformed

public void actionPerformed(ActionEvent event)

Closes the frame if the OK button is pressed.

Specified by:

actionPerformed in interface ActionListener

Parameters:

event - Event associated with OK button press.

closeFrame

public abstract void closeFrame()

Method that allows action to be performed when frame is closed. Must be implemented and should dispose of window when complete.
