C＃TestStack.White-从最小化的窗口正确获取Window.Items

Question

I am currently using the TestStack.White framework to retrieve informations from an external Window .

When the Window.DisplayState is Restored or Maximized , I can perfectly get the items that I want...but when it is Minimized , I am not able to see every item from the Window... the following examples shows the Google Chrome Items using commands in the Visual Studio Immediate Window :

MAXIMIZED WINDOW:

Window.DisplayState (COMMAND)

As you guys can see, the above example shows 35 items when the Window is Maximized , meanwhile the Minimized Window is showing only 18 items.

If I want the Panel 183101736 (first position in Maximized Window ), it can be easily get using the following code:

TestStack.White.UIItems.Panel panel = Window.Get<TestStack.White.UIItems.Panel>(SearchCriteria.ByAutomationId("183101736"));

If the Window is Minimized , I have to change its state manually using Window.DisplayState = DisplayState.Maximized ... otherwise, it will raise the following Exception . Is there a way to get "every" item without forcing the Window to be opened?

Answer 1

I think UIItems are only around, if they are rendered. A minimized window does not get rendered, so there are no UIItems to be found. To get the Items the window needs to be active, not minimized and in the foreground.

Here is a question about the last part: Is there any way to activate a window with White?

It is essentially like WebScraping with these modern javascript-pages, you can't scrape something, that is not loaded in dom yet. As opposed to an rest-service (or for windows-automation a proper ipc) it handles with the rendered interface, 'emulating' a human user - and limited to the items he would be presented.
