ExtJS 4网格面板-空格键行切换 [英] ExtJS 4 Grid Panel - Spacebar row toggle

问题描述

在ExtJS 4中，在网格面板"中选择一行(通过单击)，然后按空格键选择并取消选择该行.在ExtJS 3中不是这样，我想禁用此功能.

In ExtJS 4, selecting a row in a Grid Panel (by clicking it), and pressing the spacebar selects and de-selects the row. It was not like this in ExtJS 3, and I would like to disable this feature.

有什么想法吗?我已经开始研究Ext.util.KeyMap，看看是否可以以某种方式覆盖它.预先感谢.

Any ideas? I've begin looking into Ext.util.KeyMap to see if I could override it somehow. Thanks in advance.

推荐答案

您必须覆盖Ext.selection.RowModel的onKeyPress方法.出厂的实现是

You have to override the onKeyPress method of the Ext.selection.RowModel. The shipped implementation is

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);
            }
        }
    }
}

不幸的是，目前没有配置开关可以关闭该行为.

Unfortunately there currently is no configuration switch to turn off that behavior.
