To me grid looks like simple arithmetic, +, -, * and /, but someone
left out the description (in a fictitious book on arithmetic) of "/
"(division).
You really need to refer to the Tk documents.
Here is the Tk reference for Grid.
http://www.tcl.tk/man/tcl8.4/TkCmd/grid.htm#M18
Ah, good. You mentioned the Tk docs once, and I tried, but didn't see
this. Perhaps I didn't get beyond the blue, or just picked a few links
like -sticky.
The example at the end is, of course, in Tcl/Tk but the documentation
of the options all appllies in Tkinter as well. In particular the
explanation
of the master/slave concept and the algorithm used by grisd is useful
reading. But it is not easy stuff, it is written for professionals and
assumes a fair knowledge of GUI programming concepts.
Yes, some of the explanations like master/slave, geometry propagatio,
etc. are fleshed out, which is basically what I would like to see.
I suspect the New Mex Tech doc is among the
more comprehensive,
but not quite right for beginners.
This is a Tkinter document and as such is very good, but it
still IMHO doesn't cover the depth of the Tk docs
I would agree after seeing the above Tk doc.
The now official extension library to
Tkinter, given extra widgets.
GtK+, PyGTK,
Ah, ha. This may be places for me to explore, especially if they have
extension to canvas and anything to do with IP (img proc).
I'm not sure but since the GtK was originally developed to build the
GIMP there is a fair likeliehood that it does have some more
advanced IP stuff
Here's a big question though. Are any of
these toolkits free?
So far as I know they are all free with the minor exception of Qt
which is free in certain circumstances
FXpy,
FOX binding to Python. Binding?
What does that mean with respect to the language?
It means it is a Python wrapper around some other language
API - usually C/C++ So you can refer to the original docs and
call the functions from Python. Tkinter is a Python binding for Tk.
Likely so, how time flies. However, I'm
intrigued with some of
his topics like rubber bands, and moving items on the canvas.
If Pmw is free and available, it might be worth exercising his
draw example to see how it works.
Yes PMW is free and still available, at least for Python v2.x
Grayson's example does not use PIL. PIL doesn't do dynamic stuff like
rubber bands though, it only does the actual image
manipulation - actually creating and editing GIF/JPEG images etc
The interaction stuff you need to do using the GUI toolkit.
The GUI toolkit, Pmw, Tkinter?
To me the documentation here is like my
arithmetic analogy,
but they (say, an author of a book on the subject) left out
descriptions of both multiplication and division,
Thats because the documentors assume you know the underlying
toolkt and are only really documenting how to use it from Python.
Its like somebody writing a new mathematical notation for addition
or subtraction etc(think Matrix arithmetic say). They define the new
operations b6y allegory to the original math notation but they
assume you know how the basics work already.
