Basic status bar component that can be used as the bottom toolbar of any {@link Ext.Panel}. In addition to * supporting the standard {@link Ext.Toolbar} interface for adding buttons, menus and other items, the StatusBar * provides a greedy status element that can be aligned to either side and has convenient methods for setting the * status text and icon. You can also indicate that something is processing using the {@link #showBusy} method.

new Ext.Panel({
title: 'StatusBar',
// etc.
bbar: new Ext.ux.StatusBar({
id: 'my-status',
// defaults to use when the status is cleared:
defaultText: 'Default status text',
defaultIconCls: 'default-icon',
// values to set initially:
text: 'Ready',
iconCls: 'ready-icon',
// any standard Toolbar items:
items: [{
text: 'A Button'
}, '-', 'Plain Text']
})
});
// Update the status bar later in code:
var sb = Ext.getCmp('my-status');
sb.setStatus({
text: 'OK',
iconCls: 'ok-icon',
clear: true // auto-clear after a set interval
});
// Set the status bar to show that something is processing:
sb.showBusy();
// processing....
sb.clearStatus(); // once completeed
// Create a left-aligned status bar containing a button,
// separator and text item that will be right-aligned (default):
new Ext.Panel({
title: 'StatusBar',
// etc.
bbar: new Ext.ux.StatusBar({
defaultText: 'Default status text',
id: 'status-id',
items: [{
text: 'A Button'
}, '-', 'Plain Text']
})

// By adding the statusAlign config, this will create the
// exact same toolbar, except the status and toolbar item
// layout will be reversed from the previous example:
new Ext.Panel({
title: 'StatusBar',
// etc.
bbar: new Ext.ux.StatusBar({
defaultText: 'Default status text',
id: 'status-id',
statusAlign: 'right',
items: [{

/**
* @cfg {String} iconCls
* A CSS class that will be initially set as the status bar icon and is
* expected to provide a background image (defaults to '').
* Example usage:
// Example CSS rule:
.x-statusbar .x-status-custom {
padding-left: 25px;
background: transparent url(images/custom-icon.gif) no-repeat 3px 2px;
}
// Setting a default icon:
var sb = new Ext.ux.StatusBar({
defaultIconCls: 'x-status-custom'
});
// Changing the icon:
sb.setStatus({
text: 'New status',
iconCls: 'x-status-custom'
});

* since that is the only way to defer clearing the status. This can

* height. Use '' if the toolbar should collapse in height
* vertically when no text is specified and there are no other items in
