Re: [Phpgroupware-developers] GTK... anyone?

[Ralf Becker]

Hi Michael,

I already have a running framework for phpgw which allows phpgw 
applications to run under phpGTK from the same source as the usual HTML 
Interface: This is achived by a new template type - called eTemplates - 
which work on a basis of widgets. From theses eTemplates a class 
generates a phpGTK or a HTML user interface. There is a turorial how to 
write phpgw apps with these new eTemplates (
http://www.phpgroupware.org/cvsdemo/etemplate/doc/etemplate.html) it has 
a screenshot of an app running with phpGTK and there is a working demo 
(which creates a own session on startup) in the eTemaplates app-directory.

There is still a lot to do, til we have phpgw running fully under phpGTK ...

I would like to here from you or lets meet in IRC (let me know when you 
will be there, I'm there only frequently).

Ralf
