dijit/MenuBar¶
| Author: | Bill Keese |

The MenuBar widget models a typical menu bar like the quintessential “File” menu on (virtually?) all programs.
Introduction¶
PopupMenuBarItem widgets are the actual items in the menu, and like PopupMenuItem it displays a submenu or other widget below it. A PopupMenuBarItem always has two child nodes: a tag with the displayed label (usually in a SPAN tag), and a widget to be popped up, typically a dijit.Menu widget.
There’s also a dijit/MenuBarItem widget if you need an entry in your MenuBar that doesn’t have a drop down.
Examples¶
Programmatic example¶
require(["dojo/ready", "dijit/MenuBar", "dijit/PopupMenuBarItem", "dijit/Menu", "dijit/MenuItem", "dijit/DropDownMenu"], function(ready, MenuBar, PopupMenuBarItem, Menu, MenuItem, DropDownMenu){
ready(function(){
var pMenuBar = new MenuBar({});
var pSubMenu = new DropDownMenu({});
pSubMenu.addChild(new MenuItem({
label: "File item #1"
}));
pSubMenu.addChild(new MenuItem({
label: "File item #2"
}));
pMenuBar.addChild(new PopupMenuBarItem({
label: "File",
popup: pSubMenu
}));
var pSubMenu2 = new DropDownMenu({});
pSubMenu2.addChild(new MenuItem({
label: "Cut",
iconClass: "dijitEditorIcon dijitEditorIconCut"
}));
pSubMenu2.addChild(new MenuItem({
label: "Copy",
iconClass: "dijitEditorIcon dijitEditorIconCopy"
}));
pSubMenu2.addChild(new MenuItem({
label: "Paste",
iconClass: "dijitEditorIcon dijitEditorIconPaste"
}));
pMenuBar.addChild(new PopupMenuBarItem({
label: "Edit",
popup: pSubMenu2
}));
pMenuBar.placeAt("wrapper");
pMenuBar.startup();
});
});
<div id="wrapper"></div>
Declarative markup¶
Creation from markup is even easier.
require(["dojo/parser", "dijit/MenuBar", "dijit/MenuBarItem", "dijit/PopupMenuBarItem",
"dijit/DropDownMenu", "dijit/MenuItem"]);
<div data-dojo-type="dijit/MenuBar" id="navMenu">
<div data-dojo-type="dijit/PopupMenuBarItem">
<span>File</span>
<div data-dojo-type="dijit/DropDownMenu" id="fileMenu">
<div data-dojo-type="dijit/MenuItem" data-dojo-props="onClick:function(){alert('file 1');}">File #1</div>
<div data-dojo-type="dijit/MenuItem" data-dojo-props="onClick:function(){alert('file 2');}">File #2</div>
</div>
</div>
<div data-dojo-type="dijit/PopupMenuBarItem">
<span>Edit</span>
<div data-dojo-type="dijit/DropDownMenu" id="editMenu">
<div data-dojo-type="dijit/MenuItem" data-dojo-props="iconClass:'dijitEditorIcon dijitEditorIconCut',
onClick:function(){alert('cut!')}">Cut</div>
<div data-dojo-type="dijit/MenuItem" data-dojo-props="iconClass:'dijitEditorIcon dijitEditorIconCopy',
onClick:function(){alert('copy!')}">Copy</div>
<div data-dojo-type="dijit/MenuItem" data-dojo-props="iconClass:'dijitEditorIcon dijitEditorIconPaste',
onClick:function(){alert('paste!')}">Paste</div>
</div>
</div>
<div data-dojo-type="dijit/MenuBarItem">
Save
</div>
</div>
Icons¶
MenuBar does not support icons. If you want icons, you may be able to use dijit/Toolbar with dijit/form/DropDownButton instead of MenuBar with PopupMenuBarItems.
Accessibility¶
Keyboard¶
| Action | Key |
|---|---|
| Navigate into/out of a MenuBar | Tab or shift-tab |
| Navigate menubar items | Left and right arrow keys |
| Activate a menubar item | Spacebar or enter |
| Open a submenu | Down arrow |
| Close a submenu | Esc, or use right arrow to navigate to next menu |
Focus¶
For a static Menu/MenuBar, focus is deferred until user clicks it, or tabs into it. Once user clicks on a Menu/MenuBar, it focuses on it, and then (as with a context menu) any mouse movement or keyboard movement (via arrow keys) will change focus.
