2 * @class Ext.ux.StatusBar
3 * <p>Basic status bar component that can be used as the bottom toolbar of any {@link Ext.Panel}. In addition to
4 * supporting the standard {@link Ext.toolbar.Toolbar} interface for adding buttons, menus and other items, the StatusBar
5 * provides a greedy status element that can be aligned to either side and has convenient methods for setting the
6 * status text and icon. You can also indicate that something is processing using the {@link #showBusy} method.</p>
8 Ext.create('Ext.Panel', {
11 bbar: Ext.create('Ext.ux.StatusBar', {
14 // defaults to use when the status is cleared:
15 defaultText: 'Default status text',
16 defaultIconCls: 'default-icon',
18 // values to set initially:
20 iconCls: 'ready-icon',
22 // any standard Toolbar items:
29 // Update the status bar later in code:
30 var sb = Ext.getCmp('my-status');
34 clear: true // auto-clear after a set interval
37 // Set the status bar to show that something is processing:
42 sb.clearStatus(); // once completeed
44 * @extends Ext.toolbar.Toolbar
46 * Creates a new StatusBar
47 * @param {Object/Array} config A config object
49 Ext.define('Ext.ux.statusbar.StatusBar', {
50 extend: 'Ext.toolbar.Toolbar',
51 alternateClassName: 'Ext.ux.StatusBar',
52 alias: 'widget.statusbar',
53 requires: ['Ext.toolbar.TextItem'],
55 * @cfg {String} statusAlign
56 * The alignment of the status element within the overall StatusBar layout. When the StatusBar is rendered,
57 * it creates an internal div containing the status text and icon. Any additional Toolbar items added in the
58 * StatusBar's {@link #items} config, or added via {@link #add} or any of the supported add* methods, will be
59 * rendered, in added order, to the opposite side. The status element is greedy, so it will automatically
60 * expand to take up all sapce left over by any other items. Example usage:
62 // Create a left-aligned status bar containing a button,
63 // separator and text item that will be right-aligned (default):
64 Ext.create('Ext.Panel', {
67 bbar: Ext.create('Ext.ux.StatusBar', {
68 defaultText: 'Default status text',
76 // By adding the statusAlign config, this will create the
77 // exact same toolbar, except the status and toolbar item
78 // layout will be reversed from the previous example:
79 Ext.create('Ext.Panel', {
82 bbar: Ext.create('Ext.ux.StatusBar', {
83 defaultText: 'Default status text',
94 * @cfg {String} defaultText
95 * The default {@link #text} value. This will be used anytime the status bar is cleared with the
96 * <tt>useDefaults:true</tt> option (defaults to '').
99 * @cfg {String} defaultIconCls
100 * The default {@link #iconCls} value (see the iconCls docs for additional details about customizing the icon).
101 * This will be used anytime the status bar is cleared with the <tt>useDefaults:true</tt> option (defaults to '').
105 * A string that will be <b>initially</b> set as the status message. This string
106 * will be set as innerHTML (html tags are accepted) for the toolbar item.
107 * If not specified, the value set for <code>{@link #defaultText}</code>
111 * @cfg {String} iconCls
112 * A CSS class that will be <b>initially</b> set as the status bar icon and is
113 * expected to provide a background image (defaults to '').
114 * Example usage:<pre><code>
116 .x-statusbar .x-status-custom {
118 background: transparent url(images/custom-icon.gif) no-repeat 3px 2px;
121 // Setting a default icon:
122 var sb = Ext.create('Ext.ux.StatusBar', {
123 defaultIconCls: 'x-status-custom'
126 // Changing the icon:
129 iconCls: 'x-status-custom'
136 * The base class applied to the containing element for this component on render (defaults to 'x-statusbar')
140 * @cfg {String} busyIconCls
141 * The default <code>{@link #iconCls}</code> applied when calling
142 * <code>{@link #showBusy}</code> (defaults to <tt>'x-status-busy'</tt>).
143 * It can be overridden at any time by passing the <code>iconCls</code>
144 * argument into <code>{@link #showBusy}</code>.
146 busyIconCls : 'x-status-busy',
148 * @cfg {String} busyText
149 * The default <code>{@link #text}</code> applied when calling
150 * <code>{@link #showBusy}</code> (defaults to <tt>'Loading...'</tt>).
151 * It can be overridden at any time by passing the <code>text</code>
152 * argument into <code>{@link #showBusy}</code>.
154 busyText : 'Loading...',
156 * @cfg {Number} autoClear
157 * The number of milliseconds to wait after setting the status via
158 * <code>{@link #setStatus}</code> before automatically clearing the status
159 * text and icon (defaults to <tt>5000</tt>). Note that this only applies
160 * when passing the <tt>clear</tt> argument to <code>{@link #setStatus}</code>
161 * since that is the only way to defer clearing the status. This can
162 * be overridden by specifying a different <tt>wait</tt> value in
163 * <code>{@link #setStatus}</code>. Calls to <code>{@link #clearStatus}</code>
164 * always clear the status bar immediately and ignore this value.
169 * @cfg {String} emptyText
170 * The text string to use if no text has been set. Defaults to
171 * <tt>' '</tt>). If there are no other items in the toolbar using
172 * an empty string (<tt>''</tt>) for this value would end up in the toolbar
173 * height collapsing since the empty string will not maintain the toolbar
174 * height. Use <tt>''</tt> if the toolbar should collapse in height
175 * vertically when no text is specified and there are no other items in
178 emptyText : ' ',

214 * Sets the status {@link #text} and/or {@link #iconCls}. Also supports automatically clearing the
215 * status that was set after a specified interval.
216 * @param {Object/String} config A config object specifying what status to set, or a string assumed
217 * to be the status text (and all other options are defaulted as explained below). A config
218 * object containing any or all of the following properties can be passed:<ul>
219 * <li><tt>text</tt> {String} : (optional) The status text to display. If not specified, any current
220 * status text will remain unchanged.</li>
221 * <li><tt>iconCls</tt> {String} : (optional) The CSS class used to customize the status icon (see
222 * {@link #iconCls} for details). If not specified, any current iconCls will remain unchanged.</li>
223 * <li><tt>clear</tt> {Boolean/Number/Object} : (optional) Allows you to set an internal callback that will
224 * automatically clear the status text and iconCls after a specified amount of time has passed. If clear is not
225 * specified, the new status will not be auto-cleared and will stay until updated again or cleared using
226 * {@link #clearStatus}. If <tt>true</tt> is passed, the status will be cleared using {@link #autoClear},
227 * {@link #defaultText} and {@link #defaultIconCls} via a fade out animation. If a numeric value is passed,
228 * it will be used as the callback interval (in milliseconds), overriding the {@link #autoClear} value.
229 * All other options will be defaulted as with the boolean option. To customize any other options,
230 * you can pass an object in the format:<ul>
231 * <li><tt>wait</tt> {Number} : (optional) The number of milliseconds to wait before clearing
232 * (defaults to {@link #autoClear}).</li>
233 * <li><tt>anim</tt> {Number} : (optional) False to clear the status immediately once the callback
234 * executes (defaults to true which fades the status out).</li>
235 * <li><tt>useDefaults</tt> {Number} : (optional) False to completely clear the status text and iconCls
236 * (defaults to true which uses {@link #defaultText} and {@link #defaultIconCls}).</li>
238 * Example usage:<pre><code>
239 // Simple call to update the text
240 statusBar.setStatus('New status');

243 statusBar.setStatus({
245 iconCls: 'x-status-custom',

304 * to false which clears immediately).</li>
305 * <li><tt>useDefaults</tt> {Boolean} : (optional) True to reset the text and icon using {@link #defaultText} and
