Hello GWTer:
I am new to GWT, so please help.
I can not get cascade menuBar and rootLayoutPanel/DockLayoutPanel to
work. The cascade (second level) menubars do not display. The codes
below compile with GWT 2.0.3 and GWT 2.1.M2. The same menus work and
display properly when I used RootPanel or DockPanel.
Please help,
Jim
======================================
public void onModuleLoad() {
// Make a command that we will execute from all leaves.
Command cmd = new Command() {
public void execute() {
Window.alert("You selected a menu item!");
}
};
// Make some sub-menus that we will cascade from the top menu.
MenuBar fooMenu = new MenuBar(true);
fooMenu.addItem("thefoo", cmd);
fooMenu.addItem("foo", cmd);
fooMenu.addItem("menu", cmd);
MenuBar barMenu = new MenuBar(true);
barMenu.addItem("thebar", cmd);
barMenu.addItem("bar", cmd);
barMenu.addItem("menu", cmd);
MenuBar bazMenu = new MenuBar(true);
bazMenu.addItem("thebaz", cmd);
bazMenu.addItem("baz", cmd);
bazMenu.addItem("menu", cmd);
// Make a new menu bar, adding a few cascading menus to it.
MenuBar menu = new MenuBar();
menu.addStyleName("demo-MenuBar");
menu.addItem("foo", fooMenu);
menu.addItem("bar", barMenu);
menu.addItem("baz", bazMenu);
// Add it to the root panel. *********** This works ************
//RootPanel.get().add(menu);
/* ==========
DockLayoutPanel p = new DockLayoutPanel(Unit.EM);
p.addNorth(new HTML("header"), 6);
p.addSouth(new HTML("footer"), 2);
p.addEast(new HTML("Ads"), 10);
//p.add(new HTML("content"));
p.add(menu);
============*/
RootLayoutPanel rp = RootLayoutPanel.get();
//rp.add(p);
rp.add(menu);
}
