Deleting _track_canvas_viewport automatically destroys
any child Items. The LocationMarker's group was already destroyed
when ~ArdourMarker() runs and calls `delete group`.
So first delete the marker, then the canvas
Editor::motion_handler() only updates the snap-cursor
when no drags are active. While dragging, Drag::motion is
responsible to set the cursor accordingly.
In many cases the snap-cursor simply remained stuck at
the most recent position. Since in many cases
(e.g. RubberbandSelectDrag) it makes no sense to show the
cursor, so Drag::start_grab now hides the cursor by default.
This also fixes cases where the cursor is shown, but
was displayed in the wrong location.
This fixes undo/redo action sensitivity for non-editor
history stack changes.
Notably recording was not undoable, because the butler
thread creates the reversible "capture" command.
Historically, it was possible to grab the 1-pix-wide red line, and drag the playhead
In rare but annoying cases, the red playhead interferes with mouse clicks, because it is on top
De-sensitize the playhead by default, and provide a new config var for those who want the old operation
This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.
This concept from 2007 is no longer required Temporal::get_grid
already limits the number of grid-lines depending on the step
size (mod-bar, beat_div) and start/end positions.
This is never for inline references to parameters, only for starting parameter
documentation blocks. The "@p" command is for this, although unfortunately
Doxygen doesn't actually do anything with it and it's just an alias for code
text.
Removing the shadow makes toolbar and editor-tool buttons align
when the editor-mixer is hidden. It also improves consistency
with all other tabs that have no shadow on the left.
Increasing the table border width to 1, makes aligns the
editor-mixer button with the main toolbar.
