Hi all,
I really Love the new ListView comeing with Extjs 3.0 but I had to use the normal GridPanel I i would like to have Grouping.
Since the ListView is much much faster than the GridPanel, I decided to Extend it and add the grouping ability to it.
See what I came up with.
Ext.ux.GroupedListView = Ext.extend(Ext.ListView, {
/**
* @cfg {Boolean} startCollapsed true to start all groups collapsed (defaults to false)
*/
startCollapsed : false,
/**
* @cfg {Array} startExpanded An Array of GroupeId's that should start Collapsed
*/
startExpanded : [],
groupState : {},
initComponent : function(){
var collapsedClass = '';
if(this.startCollapsed) {
collapsedClass = ' x-grid-group-collapsed';
}
this.tpl = new Ext.XTemplate(
'<tpl for="rows">',
// grouping header
'<tpl if="xindex == 1 || parent.rows[xindex-1].group_index != parent.rows[xindex-2].group_index">',
'<div class="x-grid-group {[this.getCollapseClass(values)]}" groupeindex="{group_index}">',
'<div class="x-grid-group-hd"><div class="x-grid-group-title">{group_index} ', '</div></div>',
'<div class="x-grid-group-body">',
'</tpl>', // endof grouping header
// row template
'<dl>',
'<tpl for="parent.columns">',
'<dt style="width:{[values.width*100]}%;text-align:{align};">',
'<em unselectable="on"<tpl if="cls"> class="{cls}</tpl>">',
'{[values.tpl.apply(parent)]}',
'</em></dt>',
'</tpl>',
'<div class="x-clear"></div>',
'</dl>',
// endof row template
// grouping footer
'<tpl if="xindex == (xcount) || this.isBigger(xindex, (xcount-1)) || parent.rows[xindex-1].group_index != parent.rows[xindex].group_index"> ',
'</div>',
'</div>',
'</tpl>',
// endof grouping footer
'</tpl>',
'<div class="dataview-border"></div>',{
isBigger : function(isbigger, than) {
return isbigger > than;
},
getCollapseClass : function(values){
return values.group_collapsed ? ' x-grid-group-collapsed' : '';
}
}
);
Ext.ux.GroupedListView.superclass.initComponent.apply(this, arguments);
},
prepareData : function(recData, index, record){
var data = {},
groupId = record.data[record.store.groupField];
Ext.apply(data, recData);
data.group_index = groupId;
if(!this.groupState[groupId]) {
this.groupState[groupId] = this.startCollapsed && (this.startExpanded.indexOf(groupId) ==-1) ? false : true;
}
console.log(groupId, this.groupState[groupId]);
data.group_collapsed = !this.groupState[groupId];
return data;
},
onRender : function(){
Ext.ux.GroupedListView.superclass.onRender.apply(this, arguments);
this.innerBody.on('mousedown', this.interceptMouse, this);
},
interceptMouse : function(e){
var hd = e.getTarget('.x-grid-group-hd', this.innerBody);
if(hd){
e.stopEvent();
this.toggleGroup(hd.parentNode);
}
},
/**
* Toggles the specified group if no value is passed, otherwise sets the expanded state of the group to the value passed.
* @param {String} groupId The groupId assigned to the group (see getGroupId)
* @param {Boolean} expanded (optional)
*/
toggleGroup : function(group, expanded){
var gel = Ext.get(group);
var groupIndex = gel.getAttribute('groupeindex');
expanded = Ext.isDefined(expanded) ? expanded : gel.hasClass('x-grid-group-collapsed');
this.groupState[groupIndex] = expanded;
gel[expanded ? 'removeClass' : 'addClass']('x-grid-group-collapsed');
}
});
Ext.reg('grouinglistview', Ext.ux.GroupedListView);
