Because true is not a valid item, the tree grid will skip this invalid child item, which results in nothing happening.
树型网格将跳过这个无效的字条目,这就导致什么都没出现。
Expand selected item (tree views and search results). If the item is already expanded, this will select its first child item.
展开选择的项(树视图和搜索结果)。如果该项已经展开,这将选择它的第一个子项目。
Therefore, in the assembly, this element corresponds to two nodes: a list to hold the number of instances whose name is the same as the element name and a child item named text() inside the list.
因此在程序集中,这个元素对应于两个节点:一个用于存放实例(名称与元素名一样)数的列表和列表内一个名为 text() 的子项。
