Range select rect sticks around now after switching to the draw tool, but
disappears if a note selection is made. Not sure if draw is really the most
appropriate tool here (particularly if we ever implement actual pencil-like
drawing); edit contents seems more appropriate but that would probably cause
more selection issues, so here we are.
Fix several other cases where a single mouse click could cause several
(not nested) selection ops.
Fix missing selection memento for midi notes and midi commands.
Rename some variables.
Fix random style issues.
The user can now replay *all* earlier selection operations until the next
session undo/redo command, or the completion of a new operation.
Nothing relating to selection ops is stored, and selection operation history
is begun on first idle.
Selection operation history is fundamentally different from the history of
operations which act on a selection in terms of both their viewport and the
amount of information required to replay them.
WRT undo, the user of a selection op doesn't care about the viewport state
at the beginning of an op, but rather that at the end of the previous one.
For example, if you're in a note and something about the mode changes, it's the
underlying region context that needs to change. So, seems we need a stack of
entry contexts to deal with this sort of thing.
Switching in/out of smart mode still doesn't update immediately because we
don't have the y-coordinate needed to update it.
combines selection related editor properties with the current editor selection.
The related editor properties are:
mouse mode,
zoom setting,
left frame of the canvas,
y origin of the canvas.
Selection state now includes region views (storing the underlying region id)
and time.
This patch also fixes a region mute undo bug.
For some reason, grabbing the magic keyboard focus makes scroll stop working
regardless of what MRV::canvas_group_event() returns. I can't figure out any
reason to grab the keyboard in this case anyway, so I just removed it.
Also simlify MRV event handling code in general.
No functional changes in this one (for easier auditing), but towards having
round up/down only if necessary modes, rather than kludging around that
situation with a double round as we do currently.
This cleans up a lot of false-positives in static analysis
and also helps compilers to optimize code paths in general.
(tagging the fatal stingstream operator as ‘noreturn’ is
far less trivial)
Fix crash with midi-regions (they have a frame-handle but no x-fade).
fixes 2nd part of #5992 (backtrace 20141021-B)
This is nicer in one way: When the cursor is "trim" the x-fade
context menu is no longer accessible.
And a bit worse: The x-fade context menu is only accessible on the
small fade-handles (boxes) and on the x-fade itself.
Problem: mouse-scrolling over a MIDI region in internal edit mode
never released “magic widget focus” (mod keys and global scrolls after
that were ignored). -> added to leave_notify.
Also, the MouseModeChanged signal needs to be emitted when internal edit,
mode changes in order to trigger MidiRegionView::mouse_mode_changed(),
which in turn releases the magic focus while still hovering over a MIDI
region.
TODO: needs undo. only works in top quarter of automation lane. selection model feels weird sometimes. needs to show gain curve when you are using Range tool
