8 * @class Ext.grid.Column
9 * <p>This class encapsulates column configuration data to be used in the initialization of a
10 * {@link Ext.grid.ColumnModel ColumnModel}.</p>
11 * <p>While subclasses are provided to render data in different ways, this class renders a passed
12 * data field unchanged and is usually used for textual columns.</p>
14 Ext.grid.Column = Ext.extend(Object, {
16 * @cfg {Boolean} editable Optional. Defaults to <tt>true</tt>, enabling the configured
17 * <tt>{@link #editor}</tt>. Set to <tt>false</tt> to initially disable editing on this column.
18 * The initial configuration may be dynamically altered using
19 * {@link Ext.grid.ColumnModel}.{@link Ext.grid.ColumnModel#setEditable setEditable()}.
22 * @cfg {String} id Optional. A name which identifies this column (defaults to the column's initial
23 * ordinal position.) The <tt>id</tt> is used to create a CSS <b>class</b> name which is applied to all
24 * table cells (including headers) in that column (in this context the <tt>id</tt> does not need to be
25 * unique). The class name takes the form of <pre>x-grid3-td-<b>id</b></pre>
26 * Header cells will also receive this class name, but will also have the class <pre>x-grid3-hd</pre>
27 * So, to target header cells, use CSS selectors such as:<pre>.x-grid3-hd-row .x-grid3-td-<b>id</b></pre>
28 * The {@link Ext.grid.GridPanel#autoExpandColumn} grid config option references the column via this
32 * @cfg {String} header Optional. The header text to be used as innerHTML
33 * (html tags are accepted) to display in the Grid view. <b>Note</b>: to
34 * have a clickable header with no text displayed use <tt>' '</tt>.
37 * @cfg {Boolean} groupable Optional. If the grid is being rendered by an {@link Ext.grid.GroupingView}, this option
38 * may be used to disable the header menu item to group by the column selected. Defaults to <tt>true</tt>,
39 * which enables the header menu group option. Set to <tt>false</tt> to disable (but still show) the
40 * group option in the header menu for the column. See also <code>{@link #groupName}</code>.
43 * @cfg {String} groupName Optional. If the grid is being rendered by an {@link Ext.grid.GroupingView}, this option
44 * may be used to specify the text with which to prefix the group field value in the group header line.
45 * See also {@link #groupRenderer} and
46 * {@link Ext.grid.GroupingView}.{@link Ext.grid.GroupingView#showGroupName showGroupName}.
49 * @cfg {Function} groupRenderer <p>Optional. If the grid is being rendered by an {@link Ext.grid.GroupingView}, this option
50 * may be used to specify the function used to format the grouping field value for display in the group
51 * {@link #groupName header}. If a <tt><b>groupRenderer</b></tt> is not specified, the configured
52 * <tt><b>{@link #renderer}</b></tt> will be called; if a <tt><b>{@link #renderer}</b></tt> is also not specified
53 * the new value of the group field will be used.</p>
54 * <p>The called function (either the <tt><b>groupRenderer</b></tt> or <tt><b>{@link #renderer}</b></tt>) will be
55 * passed the following parameters:
56 * <div class="mdetail-params"><ul>
57 * <li><b>v</b> : Object<p class="sub-desc">The new value of the group field.</p></li>
58 * <li><b>unused</b> : undefined<p class="sub-desc">Unused parameter.</p></li>
59 * <li><b>r</b> : Ext.data.Record<p class="sub-desc">The Record providing the data
60 * for the row which caused group change.</p></li>
61 * <li><b>rowIndex</b> : Number<p class="sub-desc">The row index of the Record which caused group change.</p></li>
62 * <li><b>colIndex</b> : Number<p class="sub-desc">The column index of the group field.</p></li>
63 * <li><b>ds</b> : Ext.data.Store<p class="sub-desc">The Store which is providing the data Model.</p></li>
65 * <p>The function should return a string value.</p>
68 * @cfg {String} emptyGroupText Optional. If the grid is being rendered by an {@link Ext.grid.GroupingView}, this option
69 * may be used to specify the text to display when there is an empty group value. Defaults to the
70 * {@link Ext.grid.GroupingView}.{@link Ext.grid.GroupingView#emptyGroupText emptyGroupText}.
73 * @cfg {String} dataIndex <p><b>Required</b>. The name of the field in the
74 * grid's {@link Ext.data.Store}'s {@link Ext.data.Record} definition from
75 * which to draw the column's value.</p>
79 * Optional. The initial width in pixels of the column.
80 * The width of each column can also be affected if any of the following are configured:
81 * <div class="mdetail-params"><ul>
82 * <li>{@link Ext.grid.GridPanel}.<tt>{@link Ext.grid.GridPanel#autoExpandColumn autoExpandColumn}</tt></li>
83 * <li>{@link Ext.grid.GridView}.<tt>{@link Ext.grid.GridView#forceFit forceFit}</tt>
84 * <div class="sub-desc">
85 * <p>By specifying <tt>forceFit:true</tt>, {@link #fixed non-fixed width} columns will be
86 * re-proportioned (based on the relative initial widths) to fill the width of the grid so
87 * that no horizontal scrollbar is shown.</p>
89 * <li>{@link Ext.grid.GridView}.<tt>{@link Ext.grid.GridView#autoFill autoFill}</tt></li>
90 * <li>{@link Ext.grid.GridPanel}.<tt>{@link Ext.grid.GridPanel#minColumnWidth minColumnWidth}</tt></li>
91 * <br><p><b>Note</b>: when the width of each column is determined, a space on the right side
92 * is reserved for the vertical scrollbar. The
93 * {@link Ext.grid.GridView}.<tt>{@link Ext.grid.GridView#scrollOffset scrollOffset}</tt>
94 * can be modified to reduce or eliminate the reserved offset.</p>
97 * @cfg {Boolean} sortable Optional. <tt>true</tt> if sorting is to be allowed on this column.
98 * Defaults to the value of the <code>{@link Ext.grid.ColumnModel#defaultSortable}</code> property.
99 * Whether local/remote sorting is used is specified in <code>{@link Ext.data.Store#remoteSort}</code>.
102 * @cfg {Boolean} fixed Optional. <tt>true</tt> if the column width cannot be changed. Defaults to <tt>false</tt>.
105 * @cfg {Boolean} resizable Optional. <tt>false</tt> to disable column resizing. Defaults to <tt>true</tt>.
108 * @cfg {Boolean} menuDisabled Optional. <tt>true</tt> to disable the column menu. Defaults to <tt>false</tt>.
111 * @cfg {Boolean} hidden
112 * Optional. <tt>true</tt> to initially hide this column. Defaults to <tt>false</tt>.
113 * A hidden column {@link Ext.grid.GridPanel#enableColumnHide may be shown via the header row menu}.
114 * If a column is never to be shown, simply do not include this column in the Column Model at all.
117 * @cfg {String} tooltip Optional. A text string to use as the column header's tooltip. If Quicktips
118 * are enabled, this value will be used as the text of the quick tip, otherwise it will be set as the
119 * header's HTML title attribute. Defaults to ''.
122 * @cfg {Mixed} renderer
123 * <p>For an alternative to specifying a renderer see <code>{@link #xtype}</code></p>
124 * <p>Optional. A renderer is an 'interceptor' method which can be used transform data (value,
125 * appearance, etc.) before it is rendered). This may be specified in either of three ways:
126 * <div class="mdetail-params"><ul>
127 * <li>A renderer function used to return HTML markup for a cell given the cell's data value.</li>
128 * <li>A string which references a property name of the {@link Ext.util.Format} class which
129 * provides a renderer function.</li>
130 * <li>An object specifying both the renderer function, and its execution scope (<tt><b>this</b></tt>
131 * reference) e.g.:<pre style="margin-left:1.2em"><code>
133 fn: this.gridRenderer,
136 </code></pre></li></ul></div>
137 * If not specified, the default renderer uses the raw data value.</p>
138 * <p>For information about the renderer function (passed parameters, etc.), see
139 * {@link Ext.grid.ColumnModel#setRenderer}. An example of specifying renderer function inline:</p><pre><code>
140 var companyColumn = {
141 header: 'Company Name',
142 dataIndex: 'company',
143 renderer: function(value, metaData, record, rowIndex, colIndex, store) {
144 // provide the logic depending on business rules
145 // name of your own choosing to manipulate the cell depending upon
146 // the data in the underlying Record object.
147 if (value == 'whatever') {
148 //metaData.css : String : A CSS class name to add to the TD element of the cell.
149 //metaData.attr : String : An html attribute definition string to apply to
150 // the data container element within the table
151 // cell (e.g. 'style="color:red;"').
152 metaData.css = 'name-of-css-class-you-will-define';
158 * See also {@link #scope}.
161 * @cfg {String} xtype Optional. A String which references a predefined {@link Ext.grid.Column} subclass
162 * type which is preconfigured with an appropriate <code>{@link #renderer}</code> to be easily
163 * configured into a ColumnModel. The predefined {@link Ext.grid.Column} subclass types are:
164 * <div class="mdetail-params"><ul>
165 * <li><b><tt>gridcolumn</tt></b> : {@link Ext.grid.Column} (<b>Default</b>)<p class="sub-desc"></p></li>
166 * <li><b><tt>booleancolumn</tt></b> : {@link Ext.grid.BooleanColumn}<p class="sub-desc"></p></li>
167 * <li><b><tt>numbercolumn</tt></b> : {@link Ext.grid.NumberColumn}<p class="sub-desc"></p></li>
168 * <li><b><tt>datecolumn</tt></b> : {@link Ext.grid.DateColumn}<p class="sub-desc"></p></li>
169 * <li><b><tt>templatecolumn</tt></b> : {@link Ext.grid.TemplateColumn}<p class="sub-desc"></p></li>
171 * <p>Configuration properties for the specified <code>xtype</code> may be specified with
172 * the Column configuration properties, for example:</p>
174 var grid = new Ext.grid.GridPanel({
177 header: 'Last Updated',
178 dataIndex: 'lastChange',
181 //renderer: Ext.util.Format.dateRenderer('m/d/Y'),
182 xtype: 'datecolumn', // use xtype instead of renderer
183 format: 'M/d/Y' // configuration property for {@link Ext.grid.DateColumn}
191 * @cfg {Object} scope Optional. The scope (<tt><b>this</b></tt> reference) in which to execute the
192 * renderer. Defaults to the Column configuration object.
195 * @cfg {String} align Optional. Set the CSS text-align property of the column. Defaults to undefined.
198 * @cfg {String} css Optional. An inline style definition string which is applied to all table cells in the column
199 * (excluding headers). Defaults to undefined.
202 * @cfg {Boolean} hideable Optional. Specify as <tt>false</tt> to prevent the user from hiding this column
203 * (defaults to true). To disallow column hiding globally for all columns in the grid, use
204 * {@link Ext.grid.GridPanel#enableColumnHide} instead.
207 * @cfg {Ext.form.Field} editor Optional. The {@link Ext.form.Field} to use when editing values in this column
208 * if editing is supported by the grid. See <tt>{@link #editable}</tt> also.
213 * @cfg {Boolean} isColumn
214 * Used by ColumnModel setConfig method to avoid reprocessing a Column
215 * if <code>isColumn</code> is not set ColumnModel will recreate a new Ext.grid.Column
