Re: Pls Help: JMenu with 2 columns

Thanks, but that would not work for me for a number of reasons:

a) I need to have 2 different buttons:
- one that is clickable and performs an action
- another that opens a submenu that has some items that can be
clicked and perform actions

b) some LookNFeels open a menu not when you hover but only when the
user clicks on the menu itself (e.g. Motif) so this possibilty would be
problematic

Is there no way to reduce the size of those menus when they are
displayed in the popupMenu of the main Menu?

Thanks,

Ok, the problem is in LayoutManager.
Using GridLayout will not let you have columns with different width.

I made an expiriment with SpringLayout and it works fine.

public void createAndShowMenuBar() {
load = new JMenu("Load");
load.setName("Load");

int rows = 10;
LayoutManager lm = new SpringLayout();
Container cont = load.getPopupMenu();
cont.setLayout(lm);

Dimension menuSize = new Dimension(20, 5);

for (int i = 0; i < rows; i++) {
JMenu menu = new JMenu();
menu.setPreferredSize(menuSize);

for (int j = 0; j < i; j++) {
JMenuItem menuItem = new JMenuItem("InnerItem: " + i + "." + j);
menu.add(menuItem);
}

JMenuItem menuItem = new JMenuItem("MenuItem " + i);
load.add(menuItem);
load.add(menu);
}

SpringUtilities.makeCompactGrid(cont, rows, 2, 5, 5, 5, 5);

add(load);
}
