Question

I m Building a >, 并允许用户从树中删除关键物。目前,当用户使用一个顿语时,我叫起一种功能,但希望让用户仅仅在钥匙板上发布删除钥匙。

Answer 1

实际上,我是这样说的。我在《国际空间法》中添加以下内容:

onkeypress="deleteSelection(event);"

这里是我的 Java。

function deleteSelection(event){
  if(event.keyCode == KeyEvent.DOM_VK_DELETE)
  {   
    var t = document.getElementById( gs-scrapeToolbar-middlePanel-dom-tree );
    if (t.currentIndex > -1) {
      treeView.model.splice(t.currentIndex, 1);
      treeView.treeBox.rowCountChanged(t.currentIndex, -1);
    }
  }
}

Answer 2

利用关键因素确定窗口的关键短处: See tutorial here.

Answer 3

I just noted this ITreeView:

performAction()

A command API that can be used to invoke commands on the selection. The tree will automatically invoke this method when certain keys are pressed. For example, when the DEL key is pressed, performAction will be called with the delete string.

<代码> 避免采取行动(在扼杀行动中);

因此,我猜想,你能以另一种方式做到这一点:

void performAction(action) {
  if (action ==  delete ) {
    // delete the thing
  }
}

尽管我已经进行过检测。
