Summary0002717: Scroll position after the focus is lost and returned
Description

Scroll position broken after the focus is lost and returned.

Please see the attached video and steps to reproduce.

This is quite problem in our software. We'd appreciate if you can provide us with a patch to fix it. Thank you.

Steps To Reproduce
  1. Apply the attached patch to Noesis sample (Hello-world)
  2. Run HelloWorld sample
  3. Click and select the bottom-most box
  4. Scroll to the top
  5. Click any other window to make the Noesis window lost focus
  6. Click the top most box
    // The content scrolls uncontrolled and a wrong box is made selected

Are you still on 3.1.3 version?

The code that produces this situation is in FrameworkElement::OnGotFocus(), it is bringing into view the element when it gets focused.

In 3.2 we have implemented the FocusManager so we can now differentiate between logical and keyboard focus. I verified that in WPF when a window loses focus, the logical focus remains, so when returning the focus to the window, the logical focus does not change and that code in FrameworkElement is not exectuted. We will fix it for 3.2 version, but in 3.1 it will require a bit more of a hack, let me think about it to provide a patch.

Hi Sergio,

Thank you for looking into this issue immediately.

We plan to shift to 3.2.x in our next development branch. But the currently active branch is still using 3.1.3 (cannot upgrade because of risk management).

Just as an update. We are currently moving to version 3.2.3 thus we no longer need this fix for 3.1.x. Thanks.

Hello Niko,

I'm working on this issue, but in the meantime I think it is safe to just comment in FrameworkElement.cpp the LostKeyboardFocus event handler:

Index: FrameworkElement.cpp

--- FrameworkElement.cpp (revision 14313)
+++ FrameworkElement.cpp (working copy)
@@ -4396,7 +4396,7 @@
DependencyObject* focusScope = FocusManager::GetFocusScope(element);
if (focusScope != nullptr && focusScope != element && args.newFocus == nullptr)
{

  • FocusManager::SetFocusedElement(focusScope, nullptr);
  • //FocusManager::SetFocusedElement(focusScope, nullptr);
    }
    }
    });

Could you please try that?

Hi Sergio,

Thank you for the patch. We tried it that while it can fix some of the scenarios we have, there are other scenarios that still have the problems.
We then tried to find similar places and found that the remaining scenarios are fixed when we also comment out SetFocusedElement in GotKeyboardFocusEvent.
Does it make sense to you ?

If you comment the FocusManager::SetFocusedElement(focusScope, element) call in the GotKeyboardFocus event handler then IsFocused property won't be updated and GotFocus/LostFocus events will never be fired.

Can you explain what remaining scenarios don't work if you only comment the call to SetFocusedElement(nullptr) in LostKeyboardFocus()?

We fixed the issue where scroll was reset when window was deactivated and activated again, so I'm closing this ticket.
In case you find any other problem please reopen or create a new ticket.
Thanks for your feedback!
