ZPatterns implementation question: images attributes?
by Zope mailing lists 14 Jan '01

14 Jan '01

I have a specialist (actually, EMarket has a specialist <grin>) that manages objects that from a design point of view I think should have a couple of Images as attributes (thumbnail and fullsized images of the product). The question is, how do I implement this using ZPatterns? Currently all of the other object data is pulled from an SQL database. I don't mind storing the Images in the ZODB, but I'm having a hard time finguring out how I would implement that. Pointers or alternate design suggestions welcome. --RDM

How to call 'inheritedAttribute' in ZClass dtml method
by Dirksen 13 Jan '01

13 Jan '01

'testb' subclasses 'testa', and wants to call 'testa.do()' in one of its dtml method. I found in zope's source codes that zope tackles this with "testb.inheritedAttribute('do')()". Yet this doesn't work in zclass dtml method. The system complains not knowing 'testb'. How to refer to its zclass name? Any other ways for a zclass to call its base class's method? Please help!

updated main.dtml for PlugIns product for Zope 2.3
by Steve Alexander 13 Jan '01

13 Jan '01

I've put up a new main.dtml file for the PlugIns product (related to ZPatterns), for use with Zope 2.3. This replaces the previous file posted at the same URL. http://www.cat-box.net/steve/main.dtml The change makes the odd-even table row styles work consistently even when there are plug-ins in the plug-in container. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

Debugging Zope with Komodo
by Andy McKay 13 Jan '01

13 Jan '01

Aaron has just helped me get Komodo debugging working for Zope. Both Neil and I think this is absolutely fantastic, for the first time we can see the interaction of Zope internals as they happen (its no longer a black box anymore). This shed so much light on Zope, I think its great and so will any Zope developer. Many thanks to all involved in Komodo for making this happen. -- Andy McKay.

I can spare 32 pixels in height, but the current 32 pixels are worthless for me as I cannot read what is there. I do not know at what design schools one learns that black letters on dark blue background is a good thing. It seems to be quite widespread, as I see this quite often. Please keep in mind that colors do not look equal everywhere. My colors are usually dimmed as my eyes start burning when I have to look into bright light for a longer time (Zope's management screens are very difficult for me as they use bright white as background. I already looked whether I could change it, but unfortunately, the color is coded individually in each file. What about using a central style sheet instead?). Therefore, what might look good at your screen, is unrecognizable on mine (and probably others). Furthermore, you lost brand by placing the blue Zope button onto the blue stripe. You can now only guess, what is should be. While contrast is very high at most places in the new design, it is far too low in this place. Dieter

But is it really so bad to make a 32 pixel-high concession to a small pittance of branding? I know that "branding" isn't important for those who are already believers, but Zope has grown enough that its reasonable to put some effort into "first impression factor". It doesn't help the community for reviews to come out that waste words on the visual appeal shortcomings of the UI and totally miss the point. A better first impression is a Good Thing. The top frame is also a place where we might want to put more "placeless" operations like logout in the future. You can only jam so much into the tree pane without it looking very much like way too much is being jammed into the tree pane :) FWIW, one of the things we may put there later is a way to do "browser preferences" via cookies to control things like default text area sizes. That could also have a "hide top frame" option for those who really can't spare the 32px. :^) Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations www.digicool.com

New UI for 2.3
by Steve Alexander 12 Jan '01

12 Jan '01

I think the new UI for 2.3 is great improvement over 2.2. I'm already finding the sorted tables of folder contents useful, and having the add new items select at the top saves time. However, I do not like the 3-frame interface. I feel that the top frame is wasted space. The Zope logo and "Logged in as username | Logout" could as easily go at the bottom of the tree-view frame on the left. This would leave extra screen space for doing work. I realize that I can make the frame smaller by dragging it with my mouse. I do a lot of TTW development, and I think I might find that cumbersome, so I guess I'll be hacking the top frame out of my management interface :-) I also much prefer blue to black as a background colour for the tabs and the "Root Folder" link. The black seems a bit overbearing. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

Computed Attributes (was: [Zope-dev] How do I create a folder with subfolders, docs etc?)

Anwser found via a search in the searchable list archive (though it would be a bit difficult). Anwser: An attribute name must never start with "_". Though, it has not been your intend, "_" is used as an attribute name in "existingFolder._". What you should use instead is: _.getattr(existingFolder,folder_id).manage_addFolder('subFolder') Keep in mind for the future, that the right operand of "." is always a name and never an expression! When you want to use an expression, you will use "getattr" instead. Dieter
