Raw Blame History

// panel_drag.cpp — the card-drag / hover state machine seam of the docked bank panel:
// WM_MOUSEMOVE (hover + tooltip timing + the live drag), drop-target/gesture
// classification, cursor cues, button-up drop dispatch, and right-click menu routing.
// Its PURE mirrors are core/ui/card_drag (in-grid precedence + slot hit-test) and
// core/ui/drag_out (the out-of-client gesture law) — this shell supplies only the live
// rects, modifier state, and side effects. Per-mouse-move work stays plain free-function
// calls — no interface, no virtual dispatch.
//
// Compiled into the reaper_reasampler MODULE. No REAPER API functions are called
// directly here; REAPER SDK types arrive via panel_state.h.
