In Renaissance, from what I understand, the widgets leave some of their
placement properties blank/unspecified to tell the autolayout manager that they
can be resized. If a value is specified, then it will be respected, if not
then it is open to interpretation by the autolayout manager. Please correct me
on this, if I'm mistaken.
This approach is perfectly fine and can be modeled in Gorm. There is a
callback which IB/Gorm makes to the palette's main class that is used to
determine if any additional inspectors should be added to the list. If the
method is defined, it can check the conditions of the object being edited and
act accorrdingly and can add inspectors which will allow Gorm to be told to
blank out certain attributes when saving. This is the method used when you get
extra options in the inspector pulldown when you edit a text field that has an
NSFormatter instance associated with it.

I agree.. I believe that these already have the encoding logic built into
them. This was my original course anyway.

That's why I asked first. It's your framework and I didn't want to make any
changes to it that you wouldn't approve of.
Thanks, GJC

I'm a bit confused by your email - there are different ideas entangled. ;-)
It would be interesting to see what the Gorm "auto-sizing box" palette approach
would end up producing; I have my doubts about it (don't think the results will
be that useful), but it seems like a simple enough project that might easily be
attempted and might produce something usable or at least teach us something :-)
The 'Renaissance GUI builder' is a much more complex matter - as you well know
from previous discussions/threads/flamewars, I don't agree with your approach -
I
just think it will destroy the Renaissance philosophy thus failing to produce
anything different from the standard Gorm/NIB encoder, which is fine, but it's
not
what Renaissance is about (why even bothering then ? Just use XML Gorms/NIBs)!
;-)
In that light, it may be better to try the Gorm palette approach with the
gnustep-gui boxes, which are more traditional and would fit a bit better
in the Gorm philosophy - and would simplify psychologically the problem by
removing all the other Renaissance "differences" from the project - if you
concentrate on just one new bit (the auto-sizing boxes) you may get something
more useful out of it. ;-)
Thanks

Nicola,
I think that would be cool. :)
The one thing that's missing from the one's in Renaissance at this point is the
ability to encode and decode themselves using the (normal or keyed) archiver.
I suppose that can be done without any issues.
If you don't mind, I would like to extend the existing classes in Renaissance
to do this. This way, there would be a Renaissance palette that could be
used from Gorm or IB and you could use Renaissance with it's own XML format..
If I do it correctly, it will be possible to use Renaissance from within IB as
well.
There's some other thoughts, since we're on the subject, that I would like to
discuss:
Gorm's method of reading and writing model files was redesigned completely when
I implemented nib files. It has a set of Wrapper reader and writer classes for
each different format (gorm, nib, gmodel) and Gorm's internal data structures
are not coupled to any given file format. It is possible to write a set of
wrapper classes for Renaissance as well and include them in the palette
(soon... via a plugin), this would allow Gorm to read and write Renaissance
files. The only issue is that, unlike Nib and Gorm files, (and similar to
gmodels) Renaissance files lack certain meta-data about GUI that is necessary
when editing.
Loading a model file into an editor (such as Gorm or IB) is a slightly
different thing than loading it into a live application. When loading it into
a live app, all you need to know is the class you want to instantiate and it's
properties and little else about it. In the editor (where all of the classes
might not be present/linked in) you need to have a set of files that describes
these classes to the editor. Both nib and gorm wrappers contain a number of
files... a file for the
objects, a file that lists the classes that are in the file etc and any custom
classes as well as what outlets and actions are defined on them.
I'm wondering if you might be willing to extend the Renaissance format to be a
wrapper that includes this information. Once that's done, it would be possible
for Gorm to read and write Renaissance files. This might run contrary to the
goal of having gsmarkup files writable by humans, since they would have to
maintain the wrapper structure. Alternatively... Gorm could generate the
metadata file in the same directory.
Later, GJC

Just a comment - Renaissance has more powerful/advanced boxes than the
ones included
in gnustep-gui. The Renaissance ones are easier and friendlier to use
- so you
want to base any palette on the Renaissance ones! ;-)
Thanks
