[Tclplugin-core] can not input text/entry widget.

[Taguchi T. <ta...@to...>]

Hi, all.

I've installed cvsuped tclplugin to following my box:
   OS: FreeBSD5.1-current
   X:  X-Window 4.3.0
   Mozilla: mozilla-1.5

I've got some probrems.
  a. FreeBSD's libtcl84.so and libtk84.so dose not have
     -export-dynamic ld option. so I had to make patch 
     for tcl/tk FreeBSD port.
  b. Tcl Stub mechanism dosen't work. so I had to disable
     it.
     If stub mechanism is enabled, Mozilla will crash when
     read some page which contain some tclet.

Above probrems are resolved. But I still have some probrems.
First, and seriouce one is follwing:

    "I can not input any text to text and entry widget."

Selecting region using mouse is ok. but I can not input any text
using keybords.

Does anyone help me?

Thanks.

I'm assuming that you built the plugin yourself?  Did you make
not of all the special conditions in the README?

Can you elaborate more specifically on the patches required to the
configure/makefile?

This sounds similar to

Does the work-around work for you?

Yes. I use Tcl8.4.4.

a. is a probrem FreeBSD itselfs. I'll make a patch, and send it to
Tcl port maintainer for FreeBSD.
I think b is a probrem in FreeBSD or Tcl/Tk. not tclplugin. But
I'll make a workaround patch for tclplugin. I think it will save
some FreeBSD users.

Yes!
Did you resolve this probrem?

I've try to use focus command. but it did not work at all.

Thanks

P.S. Just now, I've been able to input Japanese multibyte strings
     using XIM into entry, text widget! Wow, great!!

I found another workaround.
Mozilla can Drag&Drop any links in the pages.
So Drag&Drop a link to tclet, then its tclet will get focus.
Please do not ask me "Why?" ;-)

By the way, I get other probrem.
I wrote following tag:
  <embed type="application/x-tcl" width="400" height="400"
    frameborder="NO" src="http://localhost/test.tcl">
and file test.tcl is as following:
  #!/usr/local/bin/wish8.4
  text .text
  .text insert 1.0 "Hello World!"
  pack .text

I've try to execute this tclet, but I got following error
message.

An error occured during execution of this Tclet:
invalid command name "<PRE>"
    while executing
"<PRE>"
    ("uplevel" body line 1)
    invoked from within
"upvelel #0 {<PRE>
<HR>invalid command name "text"
    while executing
"text .text"<HR>
<P><B>OUTPUT BUFFER:</B></P>
#!/usr/local/bin/wish8.4
text .tex..."

I think this message means this tclet has evaled using tclsh rather
than wish interp.

Demo tclets in tclplugin demo pages are evaled normaly. but local one
is no. Why? What should I do?

Thanks.

Sorry, Jeff.

I'm using apache rivet. so *.tcl file is evaluated as rivet
acript firstly.
Rivet is a "Tcl" interp. so any Tk command get errors.

I've modify my apache httpd.conf file. then this probrem was
resolved.

By the way, I think current tclplugin assume all tclet is
 wrriten using UTF-8 encoding.
This means, in the web page which is writen euc-jp encoding,
SCRIPT itself must use UTF-8 encoding.
Euc-jp encoded file can not contain any UTF-8 string.

I think tclet encoding may be able to set by tclet author.
such as:
   <embed type="x-application/tcl"
	  src="./sample-tclet.tcl"
	  charset="euc-jp" ...>

So I've made a patch.

I've added this (code slightly modified, requires exact match to
'encoding names') to 3.0a2.
