How to do bitmap icon in front of menu-items in Java? what is the class for menu-item in Java?

[gino]

Hi all,
I have some menu-items in Java, they are "checked" menu-items... I want to
change that "check tick" in front of the menu items to other bitmap icon to
display some fancy bitmaps in front of the menu items...

HOw can I do that in Java? Which class in AWT does this menu-item belong to?

So write your own MenuItem class or extension.

Read the documentation.

http://java.sun.com/j2se/1.3/docs/api/java/awt/MenuItem.html

java.lang.Object , java.awt.MenuComponent, java.awt.MenuItem

Don't cross-post without a reason.

I'm inclined to agree. In the past I've foundJMenus and menu items quite
limited (in terms of look and feel) and have been forced to implement my
own.

Just as it says in your Java textbook:

public class MyClass extends javax.swing.JPopupMenu
{
// your code here
}

It's not easy at all. I read the textbook. But where is the "bitmap icon"
property of this JPopupMenu that I can change?

Recall that I want to display my own bitmap icon on these menu-items...

JPopupMenu is not a menu item object. Don't you want icons next to the menu
items in the popup menu? Look under JMenuItem, the objects that populate
your popup menu.

Recall that I want to display my own bitmap icon on these menu-items...

1. JPopupMenu is not a menu item.
2. JMenuItem is.
3. JMenuItem has a setIcon method.

This result required me to read the documentation for 15 seconds. Imagine
what you can accomplish if you read the documentation for an hour.

Why, reading the documentation might be more efficient than posting here
until you have a code problem that we can help you with.

Yes, yes, JPopupMenu is not a menu item, so what shall I do to put an bitmap
icon before it or after it?

Sorry for the last post -- it was posted inadvertently.

I repeat:

Time to read the documentation. JMenuItem.setIcon().

I understood you perfectly. JMenuItem has a setIcon method that can allow me
to put a bitmap icon easily...

but JPopupMenu is not, so it does not have that setIcon() method, so I asked
what to do with this JPopupMenu...(I asked this part...)

JPopupMenu is not a visible element of your program. Only its JMenuItems
are.

JPopupMenu is not a visible element of your program. Only its JMenuItems
are.

In other words: put the icon on the JMenuItem that causes your
JPopupMenu to appear, not on the JPopupMenu. This will have the
effect of showing an icon next to the entry with the right-pointing
triangle (or whatever) in the parent menu of the popup, which is what
we assume you want.
