vue version How to expand the specified node of the treegrid component

[fengdie]

i want expand and append treegrid node.(我想要调用treegrid的事件，展开节点。或者往节点里面插入数据)
jquery version code:

Code:

        if (node.state == 'closed') {
            tree.treegrid('expand', node.id)
        } else {
            tree.treegrid('append', {
                parent: node.id,
                data  : data
            })
        }

Set the row's 'state' property with 'open' or 'closed' to expand or collapse it.

Code:

let row = ... // get your row
this.$set(row, 'state', 'closed');

Set the row's 'state' property with 'open' can't trigger 'rowExpand' event

Code:

            if (this.selectRow.state == 'closed') {
                this.$set(this.selectRow, 'state', 'open')
            }

Call this code to trigger the 'rowExpand' event.

Code:

this.$refs.tg.$emit('rowExpand', row)

trigger the 'rowExpand' event after, how to set icon 'loading'?
手动触发rowExpad事件，有点小问题。就是图标不是'loading'状态，怎么设置？


我参考了TreeGridRow.js里面，怎么在外部设置loading = true?

Code:

        toggle(event) {
            event.stopPropagation();
            if (this.isExpanded){
                this.$set(this.row, 'state', 'closed');
                this.grid.$emit('rowCollapse', this.row);
            } else {
                this.loading = true;
                this.$set(this.row, 'state', 'open');
                this.grid.$emit('rowExpand', this.row);
            }
        },

Set the row's iconCls with tree-loading to display loading icon.
