extjs - 7.x MODERN treegrid - nodecollapse/nodeexpand 事件：空行参数

Question

Ext.grid.cell.Treecollapse和expand方法应该触发nodecollapse并nodeexpand与被折叠/展开的 Ext.grid.Row

https://docs.sencha.com/extjs/7.3.1/modern/Ext.grid.Tree.html#event-nodeexpand

取而代之的是，我们得到一个空参数

Answer 1

应该覆盖这两种方法并替换me.parent为me.row

Ext.define('Override.grid.cell.Tree', {
  override: 'Ext.grid.cell.Tree',
  collapse: function() {
      var me = this;
      me.getGrid()
          .fireEventedAction('nodecollapse', [/*me.parent*/ me.row, me.getRecord(), 'collapse'], 'doToggle', me);
  },
  expand: function() {
      ...
      tree.fireEventedAction('nodeexpand', [/*me.parent*/ me.row, record, 'expand'], 'doToggle', me);
      ...
  }
