RE: [Zope] Prerequisites for a desktop IDE, or any desktop app w/ Zope

Keep it simple; I don't think a non-python and/or non-free solution would mesh well enough for new users of Zope, supposing that all of the sudden, it became a popular tool for GUI-based enterprise applications. Uh, if you are going to create a framework of python classes to do UI stuff, why base it on a foundation of Kylix? Its not true x-platform at all and even if you used it to create a "free" (whatever that means) toolkit you just add library bloat by having to support toolkits on top of toolkits on top of toolkits, none of which are free. I love Python enough to not want to move away from coding in it, even for a GUI app. I want Borland-style RAD to do this, but I'm willing to wait until I get it free, and in Python (i.e. Boa-Constructor). In the meantime, I can code in wxPython, and have nice looking apps with themed GTK widgets displayed under X, and expect that all this will run on Win32 as well - all at no cost to me as a developer (money doesn't grow on trees, for me at least) and no cost to users as well. I'm not sure if I understand what you mean by an application as a toolkit? That doesn't make sense to me: function libraries are toolkits; class libraries are toolkits. Running all this within an app sounds like the functional equivalent of running GW basic code under DOS on a 8086: you are forced to run apps inside an interpreter, there is no runtime, and this is not transparent to the user. Why force this kind of complication? To produce an IDE that won't create standalone applications, let alone ones that use simple, freely available toolkits? FYI, Inprise EULAs forbid creating competing products; for example, during the days when Borland marketed Paradox, they explitly forbit Delphi developers from using the BDE to create general-purpose database app workalikes to Borland products. Anyway, this is making the problem more complex than it needs to be; the only value Kylix has is as a RAD tool; it has no value for creating toolkits for development without the closed RAD tool, so what's the point?

But is the problem with server-side development? I wouldn't consider to do anything in Kylix on the server side. We are talking abount a GUI, which is the only reason to move away from Python at all. What I'm thinking of is: We can build a generic application using Kylix or Delphi, which has all the components in it, which are needed so far. They could be made higly configurable, and finally, that Kylix app would be like a toolkit, like wxPython is. It would be compiled once, and the executable would be freely available. Applications for this tool would then we written in Python, completely. It would configure that generic app. With this cheap trick, Kylix would be turned into a generic GUI builder tool, at no cost. > wxPython has definitely rekindled my interest in doing some desktop > development, with the idea that Zope would provide a good middleware suite / > backend for those kind of apps.

The task would be just to write such an app, not too hard probably. Delphi is written in itself, as you know. I have already written some generic application with about 20 generic widgets, which are all configurable at runtime. And Delphi is able to produce .dfm files at runtime and to read them back in. It is so self-contained that it is somehow waiting to be stolen as a generic app framework. I'm wondering why nobody does it. Maybe I should do this now. ciao - chris -- Christian Tismer :^) <mailto:tismer@tismer.com> Mission Impossible 5oftware : Have a break!

Netscape Problems
by Chris Withers 01 Jun '01

01 Jun '01

Hi, I'm getting a bit suspicious about the number of times Netscape and Zope aren't playing together for me :-S Basically, on my desktop machine (WinNT 4, Netscape 4.74) I can't actually submit to any Zope sites. I click a form button but the browser just sits there with the N spinning and not doing anything. I thought that was just my machine, but now on this laptop (Win2000, Netscape 4.74) the same thing is happening. I'm also getting the problem wit hthe browser constantly redirecting in a very short loop. IIRC, this is 'cos it's trying to get a linked stylesheet where Netscape has a bug, so I disabled sylesheets in my management options, but I still get exactly the same problem :-( Has anyone else experienced any of the above and does anyone have any solutions? cheers, Chris

RE: [Zope] dtml-tree: controlling expanded nodes
by Dunigan, Craig 01 Jun '01

01 Jun '01

Markus, I've been spending a lot of time looking into exactly this. The short answer seems to be no. The long answer is: lots of folks have tried, all have given up (that I can tell so far). It seems it would require modifying the source for the tree tag, or figuring out (without documentation, just by reading the source) how to manipulate some of the tree variables, like tree-e. From the mail list archives I've read, it looks like we can't even be sure of how the tree will respond to these variables, since it's written to *set* them, not receive them already set. I haven't given up yet, so if I come up with anything better I'll let you (and the list) know.

Getting on Zope to "talk" to another?
by Etienne Labuschagne 01 Jun '01

01 Jun '01

Hi all I have two external Python methods A and B. Python method A receives it's input from a posted form. Python method A must use Python method B to calculate some stuff for it. The only problem is that Python method B sits on another Zope machine. eg. http://myzopeserver/A?name=myName&surname=mySurname is the string that gets generated by the post form Now A does some of it's stuff, but is must get results from http://anotherzopeserver/B?personage=28 . I can probably build a string like the one above in method A and then use RESPONSE.redirect to "invoke" the method above, but what if the data that I must send to B is too big to fit in a GET type query (like above) and I must rather put it in a POST (it's actually an XML string that I want to send to the other server, it will respond with an XML string as answer.). How do I get the "form variables" generated by A into the POST, send it to B, get the response back from B and the do something with the response received from B? Any ideas on the best way to tackle this? Thanks Etienne

robots.txt
by Paz 01 Jun '01

01 Jun '01

Hi, Of course we all know about robots.txt, but I must say I havent created one in my zopeshop, yet, I see that crawlers are coming in and checking them out, with the 200 status. I don't have one in apache either which is my front-end, so where is it coming from? Does zope create on automatically? Will one that I create myself (DTML Document) in the root of zope be picked up? Thanks, Paz

Hi, I know this is kinda OT and kinda cross-post, so sue me... hehe. You can't because I live in a land where sueing is as taboo as sex is in the US... Anyhow to the point. I have busted my balls for quite a long time now to get my company's website up and running... All in Zope. I'm pretty proud of it and I'd like to say thanks to all of you who have helped this newbie out with Zope 'the world's greatest hack'... (sorry, couldn't help myself on that one..) http://shop.oratrix.nl is the url. Hope you like my effort. It's still buggy, and if people would like, send your insults to the list while I bow my head in shame. Cheers all, Paz

But, now I want to create a file that will be recognized > as a DTML METHOD. Zope doesn't care primarily about the suffix; its PUT handling (for WebDAV/FTP/HTTP PUTs) looks at the Content-Type header (if there is one; no such luch with FTP), and only reverts to guessing type from extension if it is not there. You can override the default behavior using the 'PUT_factory' hook, described at: http://dev.zope.org/Wikis/DevSite/Proposals/HookablePUTCreation Essentially, you would drop in an ExternalMethod which did the name recognition you desired, e.g.:: # Implement the "hookable PUT" hook. import re, OFS.DTMLMethod NAME_PATTERN = re.compile( '^.*\.dtml$' ) def PUT_factory( self, name, typ, body ): """ """ if NAME_PATTERN.match( name ): return OFS.DTMLMethod.DTMLMethod( '', __name__=name ) return None Tres. -- =============================================================== Tres Seaver tseaver(a)digicool.com Digital Creations "Zope Dealers" http://www.zope.org

Content-Type missing for uploads?
by Alex 01 Jun '01

01 Jun '01

How can I get the Content-Type of a file that has been uploaded with a form? example: <form method="post" enctype="multipart/form-data"> <input type="file" name="myfile"> <input type="submit"> </form> when you upload a file with this form, the browser sends the Content-Type of "myfile" , the question is: How can I get that Content-Type information from zope? By the way, it's not REQUEST.CONTENT_TYPE, as this is set to multipart/form-data. any ideas?? Thanks Alex
