* <p>A basic tab container. TabPanels can be used exactly like a standard {@link Ext.Panel}
10
* for layout purposes, but also have special support for containing child Components
11
* (<tt>{@link Ext.Container#items items}</tt>) that are managed using a
12
* {@link Ext.layout.CardLayout CardLayout layout manager}, and displayed as separate tabs.</p>
14
* <b>Note:</b> By default, a tab's close tool <i>destroys</i> the child tab Component
15
* and all its descendants. This makes the child tab Component, and all its descendants <b>unusable</b>. To enable
16
* re-use of a tab, configure the TabPanel with <b><code>{@link #autoDestroy autoDestroy: false}</code></b>.
18
* <p><b><u>TabPanel header/footer elements</u></b></p>
19
* <p>TabPanels use their {@link Ext.Panel#header header} or {@link Ext.Panel#footer footer} element
20
* (depending on the {@link #tabPosition} configuration) to accommodate the tab selector buttons.
21
* This means that a TabPanel will not display any configured title, and will not display any
22
* configured header {@link Ext.Panel#tools tools}.</p>
23
* <p>To display a header, embed the TabPanel in a {@link Ext.Panel Panel} which uses
24
* <b><tt>{@link Ext.Container#layout layout:'fit'}</tt></b>.</p>
26
* <p><b><u>Tab Events</u></b></p>
27
* <p>There is no actual tab class — each tab is simply a {@link Ext.BoxComponent Component}
28
* such as a {@link Ext.Panel Panel}. However, when rendered in a TabPanel, each child Component
29
* can fire additional events that only exist for tabs and are not available from other Components.
30
* These events are:</p>
31
* <div><ul class="mdetail-params">
32
* <li><tt><b>{@link Ext.Panel#activate activate}</b></tt> : Fires when this Component becomes
33
* the active tab.</li>
34
* <li><tt><b>{@link Ext.Panel#deactivate deactivate}</b></tt> : Fires when the Component that
35
* was the active tab becomes deactivated.</li>
37
* <p><b><u>Creating TabPanels from Code</u></b></p>
38
* <p>TabPanels can be created and rendered completely in code, as in this example:</p>
40
var tabs = new Ext.TabPanel({
41
renderTo: Ext.getBody(),
52
* <p><b><u>Creating TabPanels from Existing Markup</u></b></p>
53
* <p>TabPanels can also be rendered from pre-existing markup in a couple of ways.</p>
54
* <div><ul class="mdetail-params">
56
* <li>Pre-Structured Markup</li>
57
* <div class="sub-desc">
58
* <p>A container div with one or more nested tab divs with class <tt>'x-tab'</tt> can be rendered entirely
59
* from existing markup (See the {@link #autoTabs} example).</p>
62
* <li>Un-Structured Markup</li>
63
* <div class="sub-desc">
64
* <p>A TabPanel can also be rendered from markup that is not strictly structured by simply specifying by id
65
* which elements should be the container and the tabs. Using this method tab content can be pulled from different
66
* elements within the page by id regardless of page structure. For example:</p>
68
var tabs = new Ext.TabPanel({
72
{contentEl:'tab1', title:'Tab 1'},
73
{contentEl:'tab2', title:'Tab 2'}
77
// Note that the tabs do not have to be nested within the container (although they can be)
78
<div id="my-tabs"></div>
79
<div id="tab1" class="x-hide-display">A simple tab</div>
80
<div id="tab2" class="x-hide-display">Another one</div>
82
* Note that the tab divs in this example contain the class <tt>'x-hide-display'</tt> so that they can be rendered
83
* deferred without displaying outside the tabs. You could alternately set <tt>{@link #deferredRender} = false </tt>
84
* to render all content tabs on page load.
91
* @param {Object} config The configuration options
94
Ext.TabPanel = Ext.extend(Ext.Panel, {
96
* @cfg {Boolean} layoutOnTabChange
97
* Set to true to force a layout of the active tab when the tab is changed. Defaults to false.
98
* See {@link Ext.layout.CardLayout}.<code>{@link Ext.layout.CardLayout#layoutOnCardChange layoutOnCardChange}</code>.
101
* @cfg {String} tabCls <b>This config option is used on <u>child Components</u> of ths TabPanel.</b> A CSS
102
* class name applied to the tab strip item representing the child Component, allowing special
103
* styling to be applied.
106
* @cfg {Boolean} monitorResize True to automatically monitor window resize events and rerender the layout on
107
* browser resize (defaults to true).
109
monitorResize : true,
111
* @cfg {Boolean} deferredRender
112
* <p><tt>true</tt> by default to defer the rendering of child <tt>{@link Ext.Container#items items}</tt>
113
* to the browsers DOM until a tab is activated. <tt>false</tt> will render all contained
114
* <tt>{@link Ext.Container#items items}</tt> as soon as the {@link Ext.layout.CardLayout layout}
115
* is rendered. If there is a significant amount of content or a lot of heavy controls being
116
* rendered into panels that are not displayed by default, setting this to <tt>true</tt> might
117
* improve performance.</p>
118
* <br><p>The <tt>deferredRender</tt> property is internally passed to the layout manager for
119
* TabPanels ({@link Ext.layout.CardLayout}) as its {@link Ext.layout.CardLayout#deferredRender}
120
* configuration value.</p>
121
* <br><p><b>Note</b>: leaving <tt>deferredRender</tt> as <tt>true</tt> means that the content
122
* within an unactivated tab will not be available. For example, this means that if the TabPanel
123
* is within a {@link Ext.form.FormPanel form}, then until a tab is activated, any Fields within
124
* unactivated tabs will not be rendered, and will therefore not be submitted and will not be
125
* available to either {@link Ext.form.BasicForm#getValues getValues} or
126
* {@link Ext.form.BasicForm#setValues setValues}.</p>
128
deferredRender : true,
130
* @cfg {Number} tabWidth The initial width in pixels of each new tab (defaults to 120).
134
* @cfg {Number} minTabWidth The minimum width in pixels for each tab when {@link #resizeTabs} = true (defaults to 30).
138
* @cfg {Boolean} resizeTabs True to automatically resize each tab so that the tabs will completely fill the
139
* tab strip (defaults to false). Setting this to true may cause specific widths that might be set per tab to
140
* be overridden in order to fit them all into view (although {@link #minTabWidth} will always be honored).
144
* @cfg {Boolean} enableTabScroll True to enable scrolling to tabs that may be invisible due to overflowing the
145
* overall TabPanel width. Only available with tabPosition:'top' (defaults to false).
147
enableTabScroll : false,
149
* @cfg {Number} scrollIncrement The number of pixels to scroll each time a tab scroll button is pressed
150
* (defaults to <tt>100</tt>, or if <tt>{@link #resizeTabs} = true</tt>, the calculated tab width). Only
151
* applies when <tt>{@link #enableTabScroll} = true</tt>.
155
* @cfg {Number} scrollRepeatInterval Number of milliseconds between each scroll while a tab scroll button is
156
* continuously pressed (defaults to <tt>400</tt>).
158
scrollRepeatInterval : 400,
160
* @cfg {Float} scrollDuration The number of milliseconds that each scroll animation should last (defaults
161
* to <tt>.35</tt>). Only applies when <tt>{@link #animScroll} = true</tt>.
163
scrollDuration : 0.35,
165
* @cfg {Boolean} animScroll True to animate tab scrolling so that hidden tabs slide smoothly into view (defaults
166
* to <tt>true</tt>). Only applies when <tt>{@link #enableTabScroll} = true</tt>.
170
* @cfg {String} tabPosition The position where the tab strip should be rendered (defaults to <tt>'top'</tt>).
171
* The only other supported value is <tt>'bottom'</tt>. <b>Note</b>: tab scrolling is only supported for
172
* <tt>tabPosition: 'top'</tt>.
176
* @cfg {String} baseCls The base CSS class applied to the panel (defaults to <tt>'x-tab-panel'</tt>).
178
baseCls : 'x-tab-panel',
180
* @cfg {Boolean} autoTabs
181
* <p><tt>true</tt> to query the DOM for any divs with a class of 'x-tab' to be automatically converted
182
* to tabs and added to this panel (defaults to <tt>false</tt>). Note that the query will be executed within
183
* the scope of the container element only (so that multiple tab panels from markup can be supported via this
185
* <p>This method is only possible when the markup is structured correctly as a container with nested divs
186
* containing the class <tt>'x-tab'</tt>. To create TabPanels without these limitations, or to pull tab content
187
* from other elements on the page, see the example at the top of the class for generating tabs from markup.</p>
188
* <p>There are a couple of things to note when using this method:<ul>
189
* <li>When using the <tt>autoTabs</tt> config (as opposed to passing individual tab configs in the TabPanel's
190
* {@link #items} collection), you must use <tt>{@link #applyTo}</tt> to correctly use the specified <tt>id</tt>
191
* as the tab container. The <tt>autoTabs</tt> method <em>replaces</em> existing content with the TabPanel
193
* <li>Make sure that you set <tt>{@link #deferredRender}: false</tt> so that the content elements for each
194
* tab will be rendered into the TabPanel immediately upon page load, otherwise they will not be transformed
195
* until each tab is activated and will be visible outside the TabPanel.</li>
196
* </ul>Example usage:</p>
198
var tabs = new Ext.TabPanel({
201
deferredRender: false,
205
// This markup will be converted to a TabPanel from the code above
206
<div id="my-tabs">
207
<div class="x-tab" title="Tab 1">A simple tab</div>
208
<div class="x-tab" title="Tab 2">Another one</div>
214
* @cfg {String} autoTabSelector The CSS selector used to search for tabs in existing markup when
215
* <tt>{@link #autoTabs} = true</tt> (defaults to <tt>'div.x-tab'</tt>). This can be any valid selector
216
* supported by {@link Ext.DomQuery#select}. Note that the query will be executed within the scope of this
217
* tab panel only (so that multiple tab panels from markup can be supported on a page).
219
autoTabSelector : 'div.x-tab',
221
* @cfg {String/Number} activeTab A string id or the numeric index of the tab that should be initially
222
* activated on render (defaults to none).
226
* @cfg {Number} tabMargin The number of pixels of space to calculate into the sizing and scrolling of
227
* tabs. If you change the margin in CSS, you will need to update this value so calculations are correct
228
* with either <tt>{@link #resizeTabs}</tt> or scrolling tabs. (defaults to <tt>2</tt>)
232
* @cfg {Boolean} plain </tt>true</tt> to render the tab strip without a background container image
233
* (defaults to <tt>false</tt>).
237
* @cfg {Number} wheelIncrement For scrolling tabs, the number of pixels to increment on mouse wheel
238
* scrolling (defaults to <tt>20</tt>).
243
* This is a protected property used when concatenating tab ids to the TabPanel id for internal uniqueness.
244
* It does not generally need to be changed, but can be if external code also uses an id scheme that can
245
* potentially clash with this one.
