java ui components using buttons

Posted by jerry on December 09, 2000 at 6:00 AM

greetings

i am trying to add a button to a choice menu so that when i click on it will open the window so a user will be able to choose a selection.

i can create the button and the chocie menu , but when it comes to the action() event i am not sure what to due. the program fails to complie the way it is. i have tried several public class ChoiceMenu types but still no luck.
****************************************************************

import java.awt.*;

public class Menus extends java.applet.Applet {

public void init() {
setBackground(Color.yellow);

add(new Button("Motorcycles"));

Choice c = new Choice();

c.addItem("1967 Honda NightRider");
c.addItem("1994 Suzuki Ninja");
c.addItem("1972 Yamaha Striker");
c.addItem("None");

add(c);

}

public boolean action(Event evt, Object arg) {
if(evt.target instanceof Button)
Bikes((String)arg);

return true;

}

void Bikes(String bname) {

if (bname.equals("Motorcycles")) handleChoice(new Choice());

}

}
*****************************************************************************

after i name the arg. for the button , and create the new method . i cant find a way to call the arg. i have tried replacing new choice with just arg. that didnt work , then i added (String)arg , again that didnt work.

so i would greatly need any help you can give.

thank you jerry
