[Lmuse-user] More great routing and mixer fixes

[Tim <te...@ro...>]

Howdy lists!
Sorry for the long delay since last update.
Thanks for the suggestions and feedback.

The devil is in the details, they say.
These fixes were very, very tough. In the git master now.
Virtually every last little thing was taken care of.
Sometimes the small things are the toughest to fix.

If you love keyboards, you'll love this.
All tabbing, focus, and activation of all strip controls is fixed.
All controls accept tab, return/enter to 'edit', and escape to
  get you out of focus.
The 'extra' controls are in tabs now, as shown by Budislav.

Even if the mixer is still to change, the lessons and fixes
  applied here are solid, more secure, and good moving forward.
A lot of little 'gotcha' bugs or requirements were done.

Sorry, no time for a monitor column in the arranger yet...

Hope y'all like it.
Tim.


 From the ChangeLog, for fun:

- New: As requested: Monitor on Record Arm option. Right click any strip,
    or Global Settings.

- New: Mixer strip volume/pan affect multiple selected tracks.
   Works fully with midi <-> audio strips.
   Works in mixer and arranger, but purposely NOT in pianoroll to avoid
     accidental changes to other tracks.

   Tally of things that currently can operate on multiple selected tracks:
      Track list: Channel, port, mute, solo. Strip: Volume, pan, routing 
buttons.

- New: Strip keyboard focusing and operations: All strip controls now
     accept keyboard focus. Strip volume box is now the default PROXY focus
     for all strips. Any strip control having focus can be adjusted with
     up/down keys. Regardless of who has focus, volume and pan always
     can be adjusted with universal keys.
     Keys:
     Up/down: Adjust any focused control.
     Alt + Up/down: Adjust volume regardless of focused control.
     Alt + Left/right: Adjust pan regardless of focused control.
     Ctrl + Alt + Left/right: Switch to a neighbouring strip.
     Escape: "Get me out of this focused control to something higher-level!"
                     (Back to the arranger canvas, or the mixer window.)

- New: Show midi volume as dB option. Right click any strip, or Global 
Settings.

- To achieve midi volume as dB and support inter-strip increments, class
     MidiCtrlValList hwVal member type was changed from INT to DOUBLE.
   Was required to support fractional increments.

- New: Midi strip instrument and patch labels respond to enter/return
    key to open popup menu.

- New: As requested: Strip name labels: Double-click to edit track name,
     or right-click context menu.

- New: Strips: 'Tabs' hold palettes of controls. Extra controls have been
     moved there from right. The tabs accept keyboard focus and can
     be activated by hitting return/enter or clicking.

- Fixed: Yay! Finally the strip volume boxes have proper focus and
    mouse-over rectangles. There is a dumb problem with KDE
    Oxygen and Breeze themes: They turn off ALL such rectangles
    if the widget-to-font height ratio is too small. This required a HACK
    to force the rectangles to be drawn. Fixed with new class LineEdit,
    now is base of class DEntry.

- Fixed: Strip labels now show colour with a stylesheet active.
   Looks good with dark stylesheets. It was a problem with the order
    and way in which stylesheets were set. (And they override fonts,
    so you can't SET then READ a widget font, it always returns
    what the stylesheet set.)

- Fixed: Strip volume scale drawing was offset too much to the
    left sometimes.

- Several other fixes along the way.
