/** * This component provides a grid holding selected items from a second store of potential * members. The `store` of this component represents the selected items. The `searchStore` * represents the potentially selected items. * * The default view defined by this class is intended to be easily replaced by deriving a * new class and overriding the appropriate methods. For example, the following is a very * different view that uses a date range and a data view: * * Ext.define('App.view.DateBoundSearch', { * extend: 'Ext.view.MultiSelectorSearch', * * makeDockedItems: function () { * return { * xtype: 'toolbar', * items: [{ * xtype: 'datefield', * emptyText: 'Start date...', * flex: 1 * },{ * xtype: 'datefield', * emptyText: 'End date...', * flex: 1 * }] * }; * }, * * makeItems: function () { * return [{ * xtype: 'dataview', * itemSelector: '.search-item', * selModel: 'rowselection', * store: this.store, * scrollable: true, * tpl: * '<tpl for=".">' + * '<div class="search-item">' + * '<img src="{icon}">' + * '<div>{name}</div>' + * '</div>' + * '</tpl>' * }]; * }, * * getSearchStore: function () { * return this.items.getAt(0).getStore(); * }, * * selectRecords: function (records) { * var view = this.items.getAt(0); * return view.getSelectionModel().select(records); * } * }); * * **Important**: This class assumes there are two components with specific `reference` * names assigned to them. These are `"searchField"` and `"searchGrid"`. These components * are produced by the `makeDockedItems` and `makeItems` method, respectively. When * overriding these it is important to remember to place these `reference` values on the * appropriate components. */Ext.define('Ext.view.MultiSelectorSearch', { extend: 'Ext.panel.Panel', xtype: 'multiselector-search', layout: 'fit', floating: true, alignOnScroll: false, minWidth: 200, minHeight: 200, border: true, keyMap: { scope: 'this', ESC: 'hide' }, platformConfig: { desktop: { resizable: true }, 'tablet && rtl': { resizable: { handles: 'sw' } }, 'tablet && !rtl': { resizable: { handles: 'se' } } }, defaultListenerScope: true, referenceHolder: true, /** * @cfg {String} field * A field from your grid's store that will be used for filtering your search results. */ /** * @cfg store * @inheritdoc Ext.panel.Table#store */ /** * @cfg {String} searchText * This text is displayed as the "emptyText" of the search `textfield`. */ searchText: 'Search...', initComponent: function () { var me = this, owner = me.owner, items = me.makeItems(), i, item, records, store; me.dockedItems = me.makeDockedItems(); me.items = items; store = Ext.data.StoreManager.lookup(me.store); for (i = items.length; i--; ) { if ((item = items[i]).xtype === 'grid') { item.store = store; item.isSearchGrid = true; item.selModel = item.selModel || { type: 'checkboxmodel', pruneRemoved: false, listeners: { selectionchange: 'onSelectionChange' } }; Ext.merge(item, me.grid); if (!item.columns) { item.hideHeaders = true; item.columns = [{ flex: 1, dataIndex: me.field }]; } break; } } me.callParent(); records = me.getOwnerStore().getRange(); if (!owner.convertSelectionRecord.$nullFn) { for (i = records.length; i--; ) { records[i] = owner.convertSelectionRecord(records[i]); } } if (store.isLoading() || (store.loadCount === 0 && !store.getCount())) { // If it is NOT a preloaded store, then unless a Session is being used, // The newly loaded records will NOT match any in the ownerStore. // So we must match them by ID in order to select the same dataset. store.on('load', function() { if (!me.destroyed) { me.selectRecords(records); } }, null, {single: true}); } else { me.selectRecords(records); } }, getOwnerStore: function() { return this.owner.getStore(); }, afterShow: function () { this.callParent(arguments); // Do not focus if this was invoked by a touch gesture if (!this.invocationEvent || this.invocationEvent.pointerType !== 'touch') { var searchField = this.lookupReference('searchField'); if (searchField) { searchField.focus(); } } this.invocationEvent = null; }, /** * Returns the store that holds search results.
