v0.21.0

Migration

Current update is hudge, so Migration Guide is provided

Fixed

• When cursor entered the new surface, if iced does not update the cursor, it will kept the original cursor shape, reported by @ple1n

Changed (breaking)

• Callback, which is the callback of setting region, is renamed to RegionCB
• When setting the InputRegin, instead accessing the WlRegion, now you can only access the InputRegin, which provided many extra information
• Induce RefreshState in Refresh callback, users will know it scale_factor or resize happened
• Induce the Cursor::Hidden, allow user to hide the cursor
• Make scroll support better, and support zwp_pointer_gestures_v1 by @id3v1669
• Fix sometimes pointer cannot change
• Make the logic of redraw_policy better, make the view function be called less
• Induce Size, Position, Margin structures, instead of using the tuple of i32 or u32, make the meaning clear
• Redesign the Settings of iced_exwlshell, split it to iced::Settings and ExWlSettings.
• Redesign the exwlshellev, induce the ExWlShellHandler to address different events, instead of a simple callback function. Add the register function to bind custom events, this will help implement the a11y. Redesign the event part of exwlshellev. Nothing has changed in iced_exwlshell
• Replace RequestSetCursorShape with RequestSetCursor, using Cursor::Shape or Cursor::ThemeName. Remove ShapeName and string-based shape parsing
• Remove the pointer-enter fallback from take_popup_grab_serial

Changed

• Improve xdg toplevel support with compositor state tracking and window controls in exwlshellev and iced_exwlshell
• Allow xdg toplevel windows to parent popups
• Add popup_grab_serial alongside take_popup_grab_serial
• Support custom theme cursors, correct cursor mappings and fallbacks, and reuse the cursor surface
