The Ui_PartWindow class provides a Part Window UI object composed of three
primary areas:
- The "left area" contains the Project TabWidget which contains
the Model Tree and Property Manager (tabs). Other tabs (widgets)
can be added as needed.
- The "right area" contains the Graphics Area (i.e. glpane) displaying
the current model.
- The "bottom area" lives below the left and right areas, spanning
the full width of the part window. It can be used whenever a landscape
layout is needed (i.e. the Sequence Editor). Typically, this area is
not used and is hidden by default.
A "part window" splitter lives between the left and right areas that
allow the user to resize the shared area occupied by them. There is no
splitter between the top and bottom areas.
This class supports and is limited to a B{Single Document Interface (SDI)}.
In time, NE1 will migrate to and support a Multiple Document Interface (MDI)
to allow multiple project documents (i.e. parts, assemblies,
simulations, text files, graphs, tables, etc. documents) to be available
within the common workspace of the NE1 main window.

Return the current Property Manager widget (whether or not its tab is
chosen, but only if it has a tab), or None if there is not one.
@warning: This method's existence (not only its implementation)
is a kluge, since the right way to access that would be by asking
the "command sequencer";
but that's not yet implemented, so this is the best we can do for now.
Also, it would be better to get the top command and talk to it, not
its PM (a QWidget). Also, whatever calls this will be making
assumptions about that PM which are really only the command's business.
So in short, every call of this is in need of cleanup once we have a
working "command sequencer". (That's true of many things related to
PMs, not only this method.)
@warning: The return values are (presumably) widgets, but they can
also be mode objects and generator objects, due to excessive use of
multiple inheritance in the current PM code. So be careful what you
do with them -- they might have lots of extra methods/attrs,
and setting your own attrs in them might mess things up.

The Ui_PartWindow class provides a Part Window UI object composed of three
primary areas:
- The "left area" contains the Project TabWidget which contains
the Model Tree and Property Manager (tabs). Other tabs (widgets)
can be added as needed.
- The "right area" contains the Graphics Area (i.e. glpane) displaying
the current model.
- The "bottom area" lives below the left and right areas, spanning
the full width of the part window. It can be used whenever a landscape
layout is needed (i.e. the Sequence Editor). Typically, this area is
not used and is hidden by default.
A "part window" splitter lives between the left and right areas that
allow the user to resize the shared area occupied by them. There is no
splitter between the top and bottom areas.
This class supports and is limited to a B{Single Document Interface (SDI)}.
In time, NE1 will migrate to and support a Multiple Document Interface (MDI)
to allow multiple project documents (i.e. parts, assemblies,
simulations, text files, graphs, tables, etc. documents) to be available
within the common workspace of the NE1 main window.

Return the current Property Manager widget (whether or not its tab is

@warning: This method's existence (not only its implementation)
is a kluge, since the right way to access that would be by asking
the "command sequencer";
but that's not yet implemented, so this is the best we can do for now.
Also, it would be better to get the top command and talk to it, not
its PM (a QWidget). Also, whatever calls this will be making
assumptions about that PM which are really only the command's business.
So in short, every call of this is in need of cleanup once we have a
working "command sequencer". (That's true of many things related to
PMs, not only this method.)
@warning: The return values are (presumably) widgets, but they can
also be mode objects and generator objects, due to excessive use of
multiple inheritance in the current PM code. So be careful what you
do with them -- they might have lots of extra methods/attrs,
and setting your own attrs in them might mess things up.
