在TestStack.White中为CustomUIItem的子级获取IUIItem [] [英] Getting IUIItem[] for children of CustomUIItem in TestStack.White

问题描述

WPF应用程序正在使用应用程序框架，而我都不能编辑它们.

A WPF Application is using an Application Framework and I can edit neither of them.

我可以按照以下步骤访问GUI中的每个元素:

I can visit every element in the GUI doing something along these lines:

IUIItem[] items = window.GetMultiple(SearchCriteria.All);
foreach (var item in items)
{
    visit((dynamic)item);
}

我对常规控件没有任何问题，但是我却用CustomUIItem碰壁了.

I have no Issue with normal controls but I hit a wall with CustomUIItem.

我想访问它的所有子级，但是我无法从它们中创建一个新的数组IUIItem[].

I would like to visit all the Children of it but I fail to make a new array IUIItem[] from them.

这是我现在拥有的:

    void visit(CustomUIItem item)
    {
        AutomationElementCollection children =
            item
            .AutomationElement
            .FindAll(TreeScope.Children, Condition.TrueCondition);
        UIItemCollection temp = new UIItemCollection(children.Cast<AutomationElement>());
        foreach(var t in temp)
        {
            visit((dynamic)t);
        }
    }

这种方法会抛出Somethimes，并且大多数时候收集都保持为空.

Somethimes this throws and most of the time collection remains empty.

CusomControl在其子级中具有正常"控件. 我希望这些作为常规的IUIItem.

The CusomControl has "normal" controls among its children. I want those as regular IUIItems.

在哪里可以找到此文档. 我发现的唯一内容是此，我不能这样做，因为我只是从外面访问，我不知道控件的内容.

Where can I find the documentation for this. The only thing I found was this, and I can not do that since I am only visiting from outside and I do not know the controls content.

推荐答案

如果我真的了解您的问题.

If i have really understood your problem.

    IUIItem[] items = window.GetMultiple(SearchCriteria.All);
    foreach (var item in items)
    {
        visit(item);
    }

我已经更新了您的visit()方法，现在它以IUItem作为参数来允许访问常规控件和自定义控件.

I have update your visit() method, it takes now a IUItem as argument to allow visiting of normal and custom controls.

    public void visit(IUIItem item)
    {
        if (item is CustomUIItem)
        {
            // Process custom controls
            CustomUIItem customControl = item as CustomUIItem;

            // Retrieve all the child controls
            IUIItem[] items = customControl.AsContainer().GetMultiple(SearchCriteria.All);

            // visit all the children
            foreach (var t in items)
            {
                visit(t);
            }
            ...
        }
        else
        {
            // Process normal controls
            ...
        }
    }
