Widget layout in BASE to get table in IDL 4.0 [message #5128]

I have an application which used to work in IDL 3, but no longer produces
sensible output in IDL 4.0.

What the routine is supposed to do is produce a table of widgets with the
rows and columns nicely aligned. Using IDL 3 I could do this by creating
a BASE widget and using the COLUMN attribute to tell it how many columns
to use. Then I could fill the base with the widgets and the same number
of widgets would be put into each column and each widget would be the same
height, pretty much like a Motif RowColumn widget.

With IDL 4 this is no longer the case. The widgets are all packed into
the BASE widget and it doesn't even put the same number in each column.
The result is a free-form complete mess. I have tried creating additional
BASE, /COLUMN=1 widgets of the main BASE and then putting the table widgets
in these. This does allow me to put the correct number of widgets in each
column, but the widgets in each column are of different heights so they
don't align across. I cannot use the XSIZE and YSIZE attributes because
they are ignored for ROW/COLUMN BASE widgets.

BTW, this is not regarded as a bug, but as a new *feature*. I have been
told that this is the way it is now *meant* to work.

Does anyone have any idea how it might be possible to create a table of
widgets of different types which are aligned to a grid? I don't want to
have to use a Bulletin Board type BASE and specify the XSIZE, YSIZE,
XOFFSET, and YOFFSET of every child because a) it's very tedious and
requires alteration every time a new row or column is added, b) it only
works on one screen with one font - a different screen or font requires
all the values to be changed.
