What is the meaning of the command "tk_getOpenFile" ?
|

| maura.monville@gmail.com 2006-05-27, 10:04 pm |
| I found a command "Tcl_GetOpenFile(interp, string, write, checkUsage,
filePtr)" but its name and parameters are not he same as I see here
"tk_getOpenFile" being used.
I could non find any "tk_getOpenFile" in the Tk On-line library . Nor
this is a new Tcl/Tk command as
there is no such proc or routine.
There are 3 uses of this command whose syntax does not coincide:
set track_info(file_name) [ tk_getOpenFile \
-filetypes $track_file_types \
-defaultextension ".PLOT" \
-initialdir "." \
-initialfile $track_info(file_name) \
-title "Track data"]
set hist_info(file_name) [ tk_getOpenFile \
-filetypes $hist_file_types \
-defaultextension ".hbook" \
-initialdir "." \
-initialfile $hist_info(file_name) \
-title "HBOOK files"]
set part_file [tk_getOpenFile -filetypes $types]
I'm  . Where can I find an explanation for this command ?
Thank you.

That is a C API routine, not the Tk command of almost the same
name. The two do very different things.

??? It is there in the obvious place: Tk built-in commands.
man n tk_getOpenFile
or use a graphical (html) browser for the docs. It opens a file-selection
dialog, and returns the selected file name when done.

Sure there is.
$ wish
% info command tk_get*File
tk_getOpenFile tk_getSaveFile

Looks like the same syntax to me. The third one didn't specify many
options.

Yes, so? The first is a C API routine, the second is a Tcl/Tk procedure that
comes with Tk.

Where in the world are you looking, that has been in Tk for a very long time????

Gee, they all seem to be using the same syntax to me!
Of course the third one is not passing in as many optional parameters as the
first two, but that is why they are optional.

| No offence to Gerald or anyone else, but geniality has always been a
hallmark of the Tcl community. Surely we can answer the questions of
an exasperated newcomer to Tcl in a way that is inviting rather than
exacerbating. Kindness and consideration are in the long-term interest
of Tcl and everyone who uses it.

My apologies if I have offended you are anyone else.
I encourage you to "take over" attempting to help this "exasperated newcomer
to Tcl".

It's a timely reminder, but knowing Gerald I'm sure that he didn't
intend to be ungracious (if it was taken that way).

| For what it's worth, the first time I found the tk_* dialogs was in the
C routines section, and not in the Tk section. I didn't know about C
hooks, yet, so it was really confusing.
Maura: after implementing some examples, I think you'll find that it's
pretty easy to use, and very flexible. You can use it with no
parameters at all:
set fp [open [tk_getOpenFile]]
or with several options for a smoother experience for the user. From
the man page:
set types {
{{Text Files} {.txt} }
{{TCL Scripts} {.tcl} }
{{C Source Files} {.c} TEXT}
{{GIF Files} {.gif} }
{{GIF Files} {} GIFF}
{{All Files} * }
}
set filename [tk_getOpenFile -filetypes $types]
if {$filename != ""} {
# Open the file ...
}

I don't know where you were looking, but the manual has it:
http://www.tcl.tk/man/tcl8.4/TkCmd/getOpenFile.htm
Tcl_GetOpenFile is a C function, not a Tcl command. Don't worry about
it unless you're extending Tcl in C code.
