... Rearrange drag is now simply the default of all other hit tests.
The comment, as to the purpose of the removed call to TrackSelFunc, is
obsolete, because clicks on hidden buttons and sliders have recently been
disabled.
The mention of "the area left of the minimize button" is obsolete because there
is no such area any more after 2.2.0 layout changes.
Just before this commit, click in the minimize button but near the left edge
did not minimize, but started a track rearrange drag! That should not be so.
... Formerly it was outside of the yellow focus at the right side. Now it
follows the yellow consistently on four sides.
The constant dx in TrackPanelAx::GetLocation might be adjusted.
No change of behavior is intended at other uses of FindTrackRect
... that is, push a state only at button-up.
The undo during each drag increment didn't actually happen, because of a check
in OnUndo whether there is a drag in progress!
But this is not necessary to fix the excessive number of undo items, because
commit 63ae687bafd1123bf4bf7d00070e1dd9f38dc8a2 already did that by other means.
It only removes an unusual usage.
This reintroduces the buttons to toggle display of individual midi
channels, and cleans up the code behind that feature.
This functionality has actually been present in production versions of
audacity for a while, at least for clicking. However, the buttons
themselves were not drawn, making it exteremly painful (but possible) to
use.
As requested by PRL, this is always enabled if USE_MIDI is defined.
Clip Left
Clip Right
If the cursor lies within a clip, the clip and the cursor is moved 1 pixel left/right.
If the cursor position is at both a clip end and a clip start, the second of these clips is moved.
The movement currently ignores the snap to setting on the selection bar, and there is no snapping to the clip boundaries of other clips.
Following the behaviour or shifting with the mouse, the distance moved is rounded to an integral number of samples, and the minimum distance moved is one sample.
This gets rid of the offset rectangle hack that was needed to re-use gain
sliders for note track velocities. It also removes the need for changing
the style of a single slider. Perhaps most importantly, it fixes link
errors regarding GainSlider(int).
See https://sourceforge.net/p/audacity/mailman/message/35752524/ for
details on why this change is needed and what caused it.
The two commands are "selection to next label" and "selection to previous label".
They have default shortcuts alt+right and alt+left.
A label track does not have to be the focus. If there is a single label track in the project, that it used. If there is more than one label track, then the first label track, if any, starting at the focused track is used.
If the commands are used during playback of the project, playback continues from the new cursor/selection.
The commands provide feedback to screen readers: the name of the label, and position in the form of "i of n".
I also took the opportunity to modifier the Status Bar indications when in the TrackInfo.
1) We now mention ctrl click can select or deselect track.
2) If there is only one track, we don't now prompt about rearranging tracks, since you can't.
3) If you hover in a label track's VRuler (which is just a spacer so that things line up), you now don't get a message.
Progresses us a little towards closing. Ctrl-Click on waveform now removes track selection status, not just adds it, and we don't flicker on again subsequently when we drag. Ctrl-Click won't remove the last remaining selection (by design). Shift-Click can now reduce us down to one track, rather than the previous behaviour when reducing track selection.
