Use an explicit runtime check to apply the newer corner styling on macOS 26 while leaving behavior unchanged on older macOS versions for compatibility.
Also add the required QuartzCore framework for linking the corner curve API.
This ensures that Ctrl+H behaves like Backspace and correctly clears
the pre-edit state, preventing uncommitted characters from remaining
on the screen when using IMEs like the Japanese one on macOS.
Position the window below the notch by reducing the frame height by
safeAreaInsets.top. Create a fullscreen child window behind it with a
colored subview covering just the notch strip, matching the terminal
background color and opacity.
Also fix background_opacity not triggering a chrome update on config
reload.
Implements drag-to-reorder for window title bars, following up on the
merged window title bar feature (#9450) and the design discussion in #9619.
- Drag a title bar and drop on another title bar to swap positions
- Drop on a window body quadrant (left/right/top/bottom) to insert as
a directional split; Splits layout uses insert_window_next_to(), other
layouts fall back to move_window_to_group()
- Drop on a tab bar tab to move the window into that tab
- Drop on another OS window to move into its active tab
- Drop outside kitty to detach into a new OS window
- Tab bar highlights the hovered tab during a window drag, mirroring
how the destination window title bar is highlighted
- toggle_window_title_bars action temporarily force-shows title bars
for drag-to-reorder when they are normally hidden, auto-hiding after
the drag completes
- window_title_bar_drag_threshold option (default 5px) controls how far
the mouse must move before a drag is initiated; 0 disables dragging
MIME type follows the same convention as tab dragging:
application/net.kovidgoyal.kitty-window-{PID}
Ref: #9619
Tools like Easy Move+Resize use the macOS Accessibility API to find and
move/resize windows. They call AXUIElementCopyElementAtPosition to get the
content view, then use kAXWindowAttribute to navigate to the parent window.
The isAccessibilitySelectorAllowed: whitelist was blocking these selectors,
preventing external window management tools (Easy Move+Resize) from working with
kitty.
Fixes#5561
I think I am going to rewrite the API to integrate with the event loop,
now that I have a good handle on the semantics of DnD in the two major
platforms.
