extjs tree panel context menu not working

var menu1 = new Ext.menu.Menu({
    items: [{
        text: 'Open in new tab'

    }]
});
var treePanel = Ext.create('Ext.tree.Panel', {
    id: 'tree-panel'开发者_如何学Python,
    region: 'center',
    useArrows: true,
    singleExpand: true,
    split: false,
    height: 360,
    minSize: 150,
    rootVisible: false,
    autoScroll: true,

    border: false,
    columns: [{
        xtype: 'treecolumn',

});
treePanel.on('contextmenu', function(event, node) {
    alert(node)
    //treePanelCurrentNode = node;
    x = event.browserEvent.clientX;
    y = event.browserEvent.clientY;
    menu1.showAt([x, y]);
}, this);

Working on 4.1 ext js and trying to add context menu to this tree panel but menu is not working. In the tree panel store is coming but my code

treePanel.on('contextmenu', function(event,node){};

is not working not event

treePanel.on('click', function(event,node){};

Any idea related to ext js context menu on tree panel ?

Tree doesn't have contextmenu event in ExtJS4.

You should use itemcontextmenu instead of contextmenu:

treePanel.on('itemcontextmenu', function(view, record, item, index, event) {
    alert(record)
    //treePanelCurrentNode = record;
    menu1.showAt(event.getXY());
    event.stopEvent();
}, this);

When the data view is rendered it disabling the default right click web browser menu, this is called in listeners “render” event and “itemcontexmenu” event is for detecting right click mouse event, capture the mouse cursor position and displaying the menu.

  listeners: {


        render: function() {
             Ext.getBody().on("contextmenu", Ext.emptyFn, null, {preventDefault: true});
        },
        itemcontextmenu : function( grid, record, item, index, event){
            x = event.browserEvent.clientX;
            y = event.browserEvent.clientY;

            menu1.showAt([x, y]);


        }
}
