What does the pull request do?
This PR adds a new
StyledProperty
to theWindow
class:WindowCornerHintsProperty
, which provides hints for window corner appearance. The hint is only used on Windows, as only this platform supports controlling corner appearance.This is required for Classic.Avalonia theme to look good.
What is the current behavior?
Currently, there is no way to control window corners; it is up to Avalonia to decide which corner style to use.
What is the updated/expected behavior with this PR?
When
WindowCornerHintsProperty
is set todefault platform
,round
, ordo not round
, the appropriate corner preference is used. However, by default,WindowCornerHintsProperty
has the valueNoHint
, which indicates that it is up to Avalonia to decide which corner style should be used. This way, the default behavior is the same as it is now.How was the solution implemented (if it's not obvious)?
This PR follows the implementation of
