If you want generic file selection, use tk_getOpenFile or tk_getSaveFile
For example:
If you have a button '.b1' that the user needs to push to invoke a file
selection dialog, a simple example would be like so:
button .b1 -text Open -command {
set foofile [tk_getOpenFile -parent . -title "Open file"]
puts "File chosen is $foofile"
}
pack .b1
-------------------------------
This creates a button labeled 'Open'. When invoked, the user is presented with
a file selection dialogue. When the user selects the desired file and pu
shes OK, foofile is assigned the path to the file.
In vtcl, open the 'command' dialog for the desired widget, and put this code
into it. Voila.
tk_getOpenFile and tk_getSaveFile have several options not mentioned here. For
further explanation and arguments to these commands:
man tk_getOpenFile
man tk_getSaveFile
Hope this helps,
