Re: [R] Is it possible to pass a Tcl/Tk component as argument to afunction
John: Thanks for your reply, I spent some time on this and the conclusion is it works: top- tktoplevel() mainFrame - tkcanvas(top) both top and mainFrame can be used as parameters to pass to other function. The name, however, will conflict each other if they are defined in the same environment, which means if you have another top and mainFrame passed to another function, the GUIs will get to the same container. To avaoid this, better use different name. I wonder if there is a way for me to create an env and eliminate an env dynamically, I will try to get some information, but I definitely welcome some quick inputs...

John:
Thanks for your reply, I spent some time on this and the
conclusion is it works:
top- tktoplevel()
mainFrame - tkcanvas(top)
both top and mainFrame can be used as parameters to pass to
other function. The name, however, will conflict each other
if they are defined in the same environment, which means if
you have another top and mainFrame passed to another
function, the GUIs will get to the same container. To avaoid
this, better use different name.
I wonder if there is a way for me to create an env and
eliminate an env dynamically, I will try to get some
information, but I definitely welcome some quick inputs...
Yes, you can create and delete environments, though it's not clear to me why
you should have to do so:
env - new.env()
env
environment: 0x025f7380
parent.env(env)
environment: R_GlobalEnv
rm(env)
Regards,
John
Thanks

hi! All:
I wonder if someone has done this before...
I am writing several functions that conduct statistical
analysis using a GUI interface by Tcl/Tk, they
share many
identical GUI components. What I am trying to
do now is to
simplify the code by writing a GUI repository
for all the
components they use, thus save effort for code
maintenance.
Since they all use:
mainFrame - tkcanvas(top)
--
I wonder if I can write functions that take
mainFrame as an
argument, and call those functions from other
place with
initialized tkcanvas object. I did not see
example like this
and from my *limited* experience with tcltk, I found it
always need something to be initialized before
put to use,
that makes me wonder if this idea will work...
if it does
not, any work arounds? like using Macro?
Thanks
Hao
