How to access Zope root in Script (Python)
by Jon Whitener 08 Dec '02

08 Dec '02

How do I refer to the root Zope directory within a Python script? For example, to access the "price" object in a Page Template, (when price in a sibling or parent folder) I just say "root/service/price", but a Py script doesn't recognize "root", so what do I use? Thanks in advance, Jon Detroit, Michigan USA

RE: Qt/Free for Windows

that could have something to do with the fact that everyone is _used_ to paying for microsoft products. No one is used to paying for qt, so it's more of an issue. -----Original Message----- From: owner-qt-interest(a)trolltech.com [mailto:owner-qt-interest@trolltech.com]On Behalf Of ticktack Sent: Saturday, December 07, 2002 10:54 PM To: justin-qt(a)affinix.com Cc: qt-interest(a)trolltech.com Subject: Re: Qt/Free for Windows I really don't see the point of releasing source code for Windows. Microsoft never release any of their visual** source code, it seems that everybody using it is pretty happy with it. Now since troll release source code to unix (linux) version, Windows programmers feel unfair. The biggest reason that I probably support troll not to release source code for Windows is that I am afraid that it might help Microsoft. I don't want to see another good company being destroy by Microsoft. I don't know why people want to invest their own time to code on prepritory OS using GPL software.

RE: Qt/Free for Windows

I was referring more to the closed-source nature of the Windows operating system. from the non-commercial FAQ @trolltech: http://www.trolltech.com/developer/faqs/noncomm.html#Q3 "Why didn't you release Qt for Windows under GPL? The GNU GPL and the Trolltech QPL are open-source, respectively Free Software licenses. Note the capital "F". We are not talking "free" as in "free beer", but "Free" as in "Free Speech". We released Qt/X11 under those licenses, because it runs as major component on totally Free operating systems, such as GNU/Linux and FreeBSD. Once Microsoft Windows is completely open source, we will reconsider." -----Original Message----- From: owner-qt-interest(a)trolltech.com [mailto:owner-qt-interest@trolltech.com]On Behalf Of Justin Karneges Sent: Saturday, December 07, 2002 1:12 AM To: qt-interest(a)trolltech.com Subject: Re: Qt/Free for Windows On Friday 06 December 2002 04:32 am, Patrick Stinson wrote: > I hate to burst your bubble on the "trolls," but it is said on the > trolltech website that a qt release like that (or any, for that matter) on > windows does not follow suit with their business model. That is the reason > that they have not, and do not intend to provide a free release, post-2.3. Yes, I know. However, I think their stance might be different in light of this porting project. It doesn't matter if Trolltech refuses to make a Free version for Windows. It is bad for them if such a port exists exists _at all_, regardless if it comes from them or not. I think Trolltech should care about this. Really, the free software developers just want a more workable situation. I'm sure Trolltech could intervene with a solution for everyone, rather than wait for an independent effort that could be damaging to them. If nobody was trying, then yeah they probably wouldn't (and shouldn't) care. -Justin -- List archive and information: http://lists.trolltech.com/qt-interest/

ZClass inheritance
by Patrick Stinson 08 Dec '02

08 Dec '02

why is it that this doesn't set the inherited site_url property in the newly created instance of PK_MusicTrack? request = context.REQUEST instance = container.PK_MusicTrack.createInObjectManager(request['id'], request) request.set('site_url', instance.absolute_url()) instance.propertysheets.common.manage_editProperties(request) I realize that if PK_MusicTrack inherits site_url, it won't be in propertysheets.common, but HOW do you set it then?

When the derived class redefines an attribute ("site_url" in your case) of the inherited class, this definition hides the inherited one. But maybe, that is not your problem. When you want to access an (unhidden) attribute of the inherited class, you do it in the same way as for the own attributes: classInstance.attribute By the way, Zope implements properties as attributes. Thus, normal attriute access gives you (read only) access to properties. When you want to change a property, you must use either the PropertyManager (for standard properties, such as "title") or the PropertySheet (for properties in a property sheet) API. This is either: classInstance.manage_change/editProperties(...) (PropertyManager API) or classInstance.propertysheets.sheetName.manage_change/editProperties(...) (PropertySheet API) Note that you cannot (easily) change inherited properties when the property sheet (the property is defined in) has the same name in the inherited and derived classes (avoid identical names!). Dieter PS: Please stay on the list.

Large File Support
by Kevin Carlson 08 Dec '02

08 Dec '02

I am running Zope 2.6 on RedHat Linux version 7.2, kernel version 2.4.7-10 and, in case it matters, glibc-2.2.4-13. According to the documents that I have been reading online, the binary distribution of Zope 2.6 should have large file support built in and should work on my current configuration. However, I am unable to open a 2GB+ Data.fs file either with Zope or by typing in "open('Data.fs')" from the python interpreter (using /zope/bin/python). I routinely get a "file too large" error. Does anyone have any ideas as to why this might be happening? Thanks, Kevin

Scan for URLs from string
by Peter Bengtsson 07 Dec '02

07 Dec '02

I'm looking for a good regular expression that can spot URLs in a text string. Either that or a regular expression that can deduce whether a string piece is a URL or not. I would like to display piece of text where weblinks are converted to <A HREF... Just like when you're reading emails that contain links. Those parsing usually go by startswith("http://") or startswith("www.") I guess. Anybody got one? ...or has an idea of a module that already does this that I can nick. NB: I don't want to check the URLs using urlopen() or equivalent. Must be faster than that. Cheers, Peter

class variable persistence question
by AM 07 Dec '02

07 Dec '02

Hi, I am writing a custom user folder. In the product I have a config.py file that has a number of parameters defined that are used all over the place by other classes. These parameters specify some global variables, that I would like to set when a new instance of the product is created. If these parameters are preset then there is no problem at all, but that makes my product a bit inflexible. If I could set them when the product is instantiated, that would be great. Can I set these parameters in the manage_add method and expect them to persist for the life of the instance?? If not is there a work around for a situation like this??

Deletion of ZClass Object Does not Remove it from Catalog
by Edward Pollard 07 Dec '02

07 Dec '02

I've got my bastardised ZClass based of Page Tempate, I've made it Catalog aware. Creating the item puts it in the ZCatalog. Fantastic. With the help of this list I've constructed the appropriate forms so that editing the properties is reflected in the Catalog. Brilliant. Deleting items does not delete them from the catalog. Damn. Well, while 2 for 3 is good, I need to conquor this last little problem. I've seen discussed the issue when using a Python Product, and while in the future I'm going to endeavour to use Python Products, I'd like to fix the ZClass product I've created. Could this relate to not using the default catalog? ('Catalog') I had to change the constructor when I moved to a different Z Catalog, is there something I have to change in the destructor? (Which, really, I don't see anywhere. Do I have to create one? What on earth would it look like?) Thanks in advance, Ed
