Question

在ExtJS 4中，他们在网格面板上引入了空格键切换选择。我希望能够覆盖onKeyPress并禁用它。（我不想禁用enableKeyNav）

我尝试了什么;

//This didn't work....
Ext.override('Ext.selection.RowModel', {
    onKeyPress: function(e, t) {
      console.log(e);
    }
});
//This also didn't work...
Ext.define('MyApp.selection.RowModel', {
  override: 'Ext.selection.RowModel',
  onKeyPress: function(e, t) {
    console.log(e);
  }
});

我要覆盖的源代码;

// Select/Deselect based on pressing Spacebar.
// Assumes a SIMPLE selectionmode style
onKeyPress: function(e, t) {
    if (e.getKey() === e.SPACE) {
        e.stopEvent();
        var me = this,
        record = me.lastFocused;

        if (record) {
            if (me.isSelected(record)) {
                me.doDeselect(record, false);
            } else {
                me.doSelect(record, true);
            }
        }
    }
},

所以似乎onKeyPress在4.2.2中不存在，这就是我所使用的。

结束了......

Ext.define('MyApp.selection.RowModel', {
  override: 'Ext.selection.RowModel',
  onKeySpace: function(e) {
    console.log(e);
  }
});
