Hi Arthur!
below a simple example of how to create a menu bar and how
to handle it's events.
Hope this helps.
Ron
----------
Pre-beta-code
class MenuForm extends Frame {
// Attributes
// Constants
int formWidth = 240;
int formHeight = 300;
// Variables
MenuBar mbar; // menubar, just for testing
// Methods
public MenuForm() {
// set the title of the form by calling the parent's constructor
super("Menu Form");
initializeMenus();
setMenuBar(mbar);
resize(formWidth,formHeight);
show();
} //MenuForm
public boolean action(Event evt, Object arg) {
// Handling the menu-items
if ("Quit".equals(arg)) {
this.dispose();
}
else if ("Open".equals(arg)) {
System.out.println("Opening something...");
}
else if ("Save".equals(arg)) {
System.out.println("Saving something...");
}
else if ("Save As...".equals(arg)) {
System.out.println("Saving something as ...");
}
else if ("About".equals(arg)) {
System.out.println("Ok, ok, that's not "+
"present yet...");
}
else {
return false;
}
return true;
} // action
private void initializeMenus() {
mbar = new MenuBar();
Menu fileMn = new Menu("File");
fileMn.add(new MenuItem("New"));
fileMn.add(new MenuItem("Open..."));
fileMn.add(new MenuItem("Save"));
fileMn.add(new MenuItem("Save As..."));
fileMn.addSeparator();
fileMn.add(new MenuItem("Quit"));
mbar.add(fileMn);
Menu helpMn = new Menu("Help");
helpMn.add(new MenuItem("About"));
mbar.add(helpMn);
// Sets the help menu on the right side in the menu-bar
mbar.setHelpMenu(helpMn);
} // initializeMenus
} // MenuForm
