Areo Szkło Effect i windowStyle ustawiona na none powoduje wdowa rozmiaru nie funkcjonować prawidłowo

Question

Areo Szkło Effect i windowStyle ustawiona na none i AllowTransparency powoduje wdowa rozmiaru aby nie działać poprawnie

Po dodaniu motywu Areo Szkło do mojego okna i ustawienie WindowState to None, okno nie zmienia się poprawnie. Mogę iść tak duży, jak chcę, ale gdy zmniejszam rozmiar, efekt szkła pozostaje na tej samej szerokości i wysokości.

Na przykład klikam Maksymalizuj. Okno Rozwija się na cały ekran. Ale po przywróceniu moje okno przywraca z powrotem, ale nie efekt szkła.

Wszystko, czego naprawdę chcę, to efekt rozmycia. Nie dbam o szkło, ale wydaje mi się, że to jedyny sposób, w jaki mogę uzyskać przezroczyste rozmycie.

Jak mogę to naprawić? To doprowadza mnie do szału! Proszę pomóż.

AnyOne ???

Answer 1

Wydaje się, że AllowsTransparency == True jest źródłem tego zachowania. Dlatego możesz go usunąć. Jednakże, należy ustawić przezroczystość tła Brush wynosi zero:

<Window.Background> 
    <SolidColorBrush Opacity="0" Color="Transparent"/> 
</Window.Background> 

to wraz z ustawieniem CompositionTarget.BackgroundColor być przejrzyste, a także za pomocą DwmEnableBlurBehindWindow funkcji sprawi, podobny wynik do ustawiania AllowsTransparency == True.

Jednak dzięki tym modyfikacjom wygląd okna nie jest zbyt przyjemny ze względu na jego obramowanie. Obramowanie zniknie, jeśli ustawisz ResizeMode=="NoResize". Jednak w takim przypadku powinieneś zaimplementować zmianę rozmiaru siebie. Na szczęście jest to łatwe dzięki dodaniu kciuka i obsłudze zdarzenia DragDelta. Oto pełny kod:
