使用FlaUI Automation在WPF应用程序中获取进度条的可见性 [英] Getting the visibility of a progress bar in a WPF application using FlaUI Automation

问题描述

我正在使用 FlaUI 自动化 WPF 应用.我有一个进度栏，它是 Inderminate .进度栏获得合拢后，即会加载 UI .我想在ProgressBar Visibility上实现Retry机制，但无法通过FlaUI

I am automating a WPF app using FlaUI. I have a progressbar that is Inderminate. Once the progressbar gets Collapsed, The UI is loaded. I want to implement a Retry mechanism on the ProgressBar Visibility but I am not able to find the correct property through FlaUI

private ProgressBar LoadingStatus => _uiAutomation.FindElement("ShowProgress", Automation.FindBy.Id).AsProgressBar();

<ProgressBar AutomationProperties.AutomationId="ShowProgress"
                Grid.Row="1"
                Height="4"
                Margin="0"
                BorderThickness="0"
                IsIndeterminate="True"
                IsTabStop="False"
                ToolTip="Contacting Server, Please Wait..."
                Visibility="{Binding IsServerActive, Converter={StaticResource MwBoolToVisibilityConverterReverse}}" />

我想实现Retry.While((LoadingStaus_Is_Collapsed)=> )};，但似乎我无权访问visibility属性. 我该怎么办?

I want to implement a Retry.While((LoadingStaus_Is_Collapsed)=> )};but seems like I don't have access to the visibility property. How can I get it done?

推荐答案

在这里起作用的属性是IsOffScreen. UIA框架提供此属性，因为可见性是WPF属性而不是UIA. 如果元素当前不在屏幕上，则IsOffScreen返回True，否则返回False. 这就是我的用法

The property that works here is IsOffScreen. The UIA framework provides this property as Visibility is a WPF property and not UIA. IsOffScreen returns True if the element is not currently on the screen else returns False. This is how I used it

public bool LoadingStatusVisibiltity()
        {
            _logger.Info("Retrieving data from the server.Please wait!");
            if (LoadingStatus.IsOffscreen)
            {
                return true;
            }
            else
            {
                return false;
            }
        }
