[Jsynthlib-devel] Change in DeviceAddDialog

[Joe E. <jo...@em...>]

Okay guys... I changed the JList to a JTree in DeviceAddDialog.

Do a CVS update and try adding a synth. The stuff you see on the screen 
doesn't look like much... but I really cleaned up the underlying code.

---------------------------------
Explaination of the layout
---------------------------------
The tree supports grouping by manufacturer, type (ie, synth, controller, 
drum machine, etc.), manufacturer-then-type, type-then-manufacturer, or 
no grouping at all (in which case it looks just like the old JList, 
pretty much).

It is *currently* configured to group by Type, then by Manufacturer. The 
problem is, devices don't have types yet. In the meantime, so that we 
have something to test, the type is the first letter of the manufacturer 
name. So, a "Kawai K4" will have type "K". This is why the tree 
initially starts out with just a bunch of folders with single-letter 
names. So, the Kawai K4 is in "/K/Kawai/Kawai K4".

If you want to experiment with different groupings, look in 
DeviceSelectionTree and change the groupStyle field to GROUP_NONE, 
GROUP_MANUF, GROUP_TYPE, GROUP_MANUF_TYPE, or GROUP_TYPE_MANUF (which is 
what it is now). Should we just hard-code this a certain way, or let the 
user change it with a setting?

--------------------------------
Things to watch out for
--------------------------------
Keep an eye out for any time the tree isn't in alphabetical order. I 
tried to remember to keep it sorted in all of the different groupings, 
but I might have missed something.

Also, you shouldn't be able to select or double-click on any tree items 
*except* the actual devices. Double-clicking on a type or manufacturer 
shouldn't do anything. Double-clicking on an acutal device, however, is 
treated as though you selected it and clicked OK.

--------------------------
Future possibilities
--------------------------
Sorry I'm obsessing over this, but this is one of the first things a new 
user sees, so I'd like to make it as snazzy as I can....

JTree's support custom icons and images in places of the little 
folder/document icons used for nodes and leafs. When we do, someday, 
support types, I'd like to consider having some little icons which look 
like the various types (drum machine, rackmount synth, keyboard, etc).

Also, if I'm inspired later, I could go in and add support for selecting 
multiple synths at a time.
