TK Directory question

Ruby
1

Hello,

I am working on a GUI that allows the user to select a file to work on.
I am using Tk.getOpenFile to do this. I would like the application to
‘remember’ the file path from the last time they selected a file, so
that the user does not have to browse to the same location over and
over. I cannot find any info on how to do this.

Any help would be greatly appreciated. Thanks.

Hi,
a way is

  1. memorize into a var the last directory:

file = Tk.getOpenFile
@last_dir = File.dirname(file) if !file.nil?

  1. use the option ‘initialdir’ of Tk.getOpenFile

file = Tk.getOpenFile(‘initialdir’=>@last_dir)
