We no longer assume that Snap always uses the visible ruler lines.
If you want to snap to the grid, and ignore the users zoom scale, use SnapPref::SnapToGrid_Unscaled
This fixes 2 (known) oversights: "snap region(s) to grid" and "regions whose start are left of the canvas edge".
Separate Snap from Grid. Lots of naming changes.
Multiple simultaneous snap options allowed. Grid is one of the possible Snap options.
Grid uses the same data as the rulers. Replace complicated tempo_lines with simple grid_lines.
The Grid is zoom-scale-sensitive along with the rulers. If you are zoomed out, grid becomes coarser.
Snapped Cursor is a line that follows the edit point, and indicates where the operation will occur.
This replaces and extends the line that appears with the Cut tool.
New associated preferences: snap_threshold and show_snap_cursor.
Generated by tools/f2s. Some hand-editing will be required in a few places to fix up comments related to timecode
and video in order to keep the legible
- wysiwyg (during drag) when dragging more than one note across
a tempo change.
- introduces a muscal equivalent of snap_delta (only used for
note drags atm)
- split earliest note in selection into a separate function
- MRV::copy_selection() returns the equivalent _primary note
to avoid offset hell.
- RV::snap_frame_to_frame returns a MusicFrame
- prevent note drag moving before region start.
- don't add a new SysEx canvas item every time we zoom or drag.
- speed up redisplay generally using PatchChange-like method
for finding items (find_canvas_sys_ex() in boost::unordered_map).
snap now fills in a struct (MusicFrame) which contins a snapped frame
along with a music divisor.
this gives useful information wrt magnetic snap which may or may not
have rounded to an exact musical position.
region position may now be set musically (using quarter notes for now).
this patch fixes several problems in the current code:
- dragging a list of music-locked regions now maintains correct
musical offsets within the list.
- splitting regions using magnetic snap works correctly (#7192)
- cut drag should now work correctly with magnetic snap.
- musical length of split midi regions is no longer frame based.
