protected java.awt.Font font

The font used for this dialog.

wasMoved

protected boolean wasMoved

Tells whether this dialog has moved or not from the center of the screen. Initially, any javabook dialog is displayed at the center of the screen. But once this dialog is moved and shown again, it will be shown at the position it was last moved to.

Constructor Detail

JavaBookDialog

public JavaBookDialog(java.awt.Frame owner)

Creates a modal dialog. This constructor is called from a constructor of one of the subclasses. You cannot call this constructor directly as this class is an abstract class.

Parameters:

JavaBookDialog

public JavaBookDialog(java.awt.Frame owner,
                      boolean modal)

Creates a modal or modeless dialog. The second parameter determines this dialog's modality: true for modal and false for modeless. This constructor is called from a constructor of one of the subclasses. You cannot call this constructor directly as this class is an abstract class.

modal - true for modal and false for modeless dialog

Method Detail

setVisible

public void setVisible(boolean view)

Changes the visibility of this dialog. When the boolean parameter view is true, then this dialog becomes visible. Otherwise, this dialog is hidden (not visible) from the screen.

setVisible in class java.awt.Component

Parameters:

view - true for visible and false for not visible

Parameters:

e - the WindowEvent object.

windowClosing

public void windowClosing(java.awt.event.WindowEvent e)

Implements the required method of the WindowListener. Disposes native window resources allocated to this dialog. Do not call this method. The Java virtual machine handles the window event processing.

Specified by:

windowClosing in interface java.awt.event.WindowListener

Parameters:

e - the WindowEvent object.

windowClosed

public void windowClosed(java.awt.event.WindowEvent e)

Implements the required method of the WindowListener. This method does nothing. Do not call this method. The Java virtual machine handles the window event processing.

Specified by:

windowClosed in interface java.awt.event.WindowListener

Parameters:

e - the WindowEvent object.

windowIconified

public void windowIconified(java.awt.event.WindowEvent e)

Implements the required method of the WindowListener. This method does nothing. Do not call this method. The Java virtual machine handles the window event processing.

Specified by:

windowIconified in interface java.awt.event.WindowListener

Parameters:

e - the WindowEvent object.

windowDeiconified

public void windowDeiconified(java.awt.event.WindowEvent e)

Specified by:

windowDeiconified in interface java.awt.event.WindowListener

Parameters:

e - the WindowEvent object.

windowActivated

public void windowActivated(java.awt.event.WindowEvent e)

Implements the required method of the WindowListener. This method does nothing. Do not call this method. The Java virtual machine handles the window event processing.

Specified by:

windowActivated in interface java.awt.event.WindowListener

Parameters:

e - the WindowEvent object.

windowDeactivated

public void windowDeactivated(java.awt.event.WindowEvent e)

Implements the required method of the WindowListener. This method does nothing. Do not call this method. The Java virtual machine handles the window event processing.

Specified by:

windowDeactivated in interface java.awt.event.WindowListener
