GUI

What is it called when a program is written to respond to the button clicks, menu selections, and other actions of the user in whatever order the user does them?

• Event-driven programming.

• Action-driven programming.

• User-driven programming.

• Mouse-driven programming

Usually GUI programs are written by using existing software components provided in a toolkit. The Java toolkit used in this chapter is the:

• GUI toolkit

• Abstract Windowing Toolkit

• Graphics Event Toolkit

• Java Enhancement Toolkit

The three software parts of a GUI program are:

• Windows, Buttons, Mice

• GUI Components, Graphics, Code

• GUI Components, Event Listeners, Application Code

• Frames, Code, Events

What is the one component that nearly all GUI programs will have?

• Frame

• Mouse

• Monitor

• Button

What is a container object in GUI programming?

• container is another name for an array or vector.

• container is any class that is made up of other classes.

• container is a primitive variable that contains the actual data.

• container is an object like a Frame that has other GUI components placed inside of it.

Which of the following sets the frame to 300 pixels wide by 200 high?

• frm.setSize( 300, 200 );

• frm.setSize( 200, 300 );

• frm.paint( 300, 200 );

• frm.setVisible( 300, 200 );

When is the paint() method of a frame object called?

• The user calls it to display the frame.

• The main() method calls it once when the program starts.

• The Java system calls it every time it decides to display the frame.

• The Java system calls it once when the program starts.

What is a Graphics object?

• The Graphics object represents the part of the Frame that you can draw on

• The Graphics object represents the whole Frame.

• The Graphics object represents the entire monitor.

• The Graphics object represents the graphics board.

Fill in the blanks so that this program displays a Frame:

import java.awt.*;

public class microGUI

{

public static void main ( String[] args )

{

Frame frm = new ___________();

frm.___________( 150, 100 );

frm.___________( true );

}

}

• Form, setVisible, setOn

• Frame, setSize, setVisible

• Frame, setVisible, setSize

• Window, setSize, paint
