folks, hi, just an update: i was advised kindly to look at pywebkitgtk - which i downloaded and compiled from source, this morning. _wow_ am i dead impressed with this project! the demo browser example ran my javascript-only web site, http://lkcl.net and it _nearly_ managed to run my javascript-only site i'm developing, http://partyliveonline.com - except it segfaulted after login. _wow_ would i have been so impressed if it had worked first time :) the concept of having a standards-compliant browser, integrateable into apps using python... _wow_ :) anyway: i added in pywebkitgtk instead of python-gtkhtml2 and was pleased to find that it worked absolutely perfectly to provide [a missing] gtk.HTML-like widget. what i was _less_ impressed with is that it suffers *exactly* the same flaw that python-gtkhtml2 has: a widget created with pywebkitgtk *cannot* tell you what its width and height is, and so, if you insert it into an app, and the app size "shrinks", the HTML - even if it's one line of HTML - gets "chopped off". there's no enforcement of HTML content "size" communicated back to the gtk.Widget "container". thus, sadly, pywebkitgtk is as useless as python-gtkhtml2 for doing the simple, simple job of putting HTML as simple as " < b>hello< /b >" into an application. also i haven't checked yet if "object_requested" is supported in pywebkitgtk or its equivalent - i hope so, because it's absolutely essential functionality . qt4 has support for "Rich Text" - simple things like "< b >hello< /b >" can be detected and displayed, and the size of the box is "enforced" as a minimum width and height onto the application. it's _essential_ that GTK have similar such functionality. implementing these features "outside" of the core gtk widget set - using pygtk2 alone - registers on the "awkward to literally impossible" scale. l. p.s. for those people on the gtk-devel mailing list, information on the context for this message can be found at: http://advogato.org/person/lkcl and at http://lkcl.net/pyjamas-desktop - i am porting pyjamas - the python-to-javascript compiler - to pygtk2 _and_ pyqt4 _and_ iron-python with gtk-sharp _and_ i will be looking at qyoto, at a later date. see http://lkcl.net/pyjamas-desktop - pygtk2.tgz for progress on the python-gtk2 port.

ok. thanks sam.
to gtk developers: i'm going to have to terminate work on python-desktop's gkt2 widget set until a solution is available: python-gtkhtml3 or other solution. it's simply not ok to have widgets that force you to specify both the width and the height, and if you don't do so, they just... don't work.
python-gtkhtml2 views, if you specify only the width, the height remains at zero: that's unacceptable.
in gtk-sharp, Gtk.HTML works absolutely fine (iirc correctly)

sam, hi, did you ever receive a reply - or find a solution - to this question? for http://lkcl.net/pyjamas-desktop i'm looking for the way to calculate a sensible size for gtkhtml2.Views, based on the HTML inside. at present, exactly as you probably found, a popup dialog is created... with zero width and height. only by having set the width to a fixed pixel size is the dialog turning out to be 1 pixel high (and 218 pixels wide), and the user application chose that.
Nope.
