Text widget focus problem

[S-Y. Chen]

Dear All,

I am having this focus problem on text widget, and wondering if anyone
can help. It is different with the one mentioned by someone before

I force tcl shell to load tk dll, and read in a script to create menu,
text, etc when it started. I can not type in anything in the widget,
unless I do one of the following

1. Click on the command console, and click back on the text widget.
Or
2. Load something into the text widget.

I suppose that is because my initial text is actually empty ? Or
something else ?

Any help will be greatly appreciated.

Regards

Do you have a small script that reproduces this problem?

I was unable to reproduce the problem with a small script. My version
of Tcl/Tk is heavily modified in the C source code level and it is too
difficult for me to reproduce it with a small script.

However I was able to pin-point the problem. It seems to be the
"tk_chooseDirectory" command causing the problem.

Here is what I have obverved

1. If I do not invoke this command in my initialization script, I can
type into text widget directly.
2. If I invoke this command twice in my initialization script, I can
type into text widget directly too.
3. Typing "tk_chooseDirectory" did not cause the problem. Because as I
have said, once I have focus on the command console (even without
doing anything), I can type in my text widget again.

I don't know if this helps. I am still trying to find out a solution.

Hello,

Since you are loading Tk into a tclsh shell, this looks similar to issue
discussed here:

Yes. I was able to type in text widget, after I add

tkwait visibility .

before the

tk_chooseDirectory

Thanks a lot !
