UI openpanel - path issue?

tomot

The sketchup-ruby-api shows Arguments: title, directory, filename
There is no example of how to change the directory to a user path:
Can UI openpanel be used to point to a path as below ?

c:\Program flies (x86)\Goggle\Google SketchUp 8\Plugins\my dir

Yes, of course.
BUT you will need to enclose the path as a string in '', OR if you use "" you must escape every \ as \, OR you can use / instead. The \ only works on PC, but both PC and MAC use / OK.
If you have a Plugin with a folder in the same folder - then use
folder=File.join(File.dirname(__FILE__), 'my dir')
and pass 'folder' to the method [for UI.openpanel as the 2nd argument]...
It will find the path to the folder 'my dir' inside the Plugins folder automatically OR wherever the script is located.

If you are asking, "Can UI.openpanel return a path?"
yes... by hotwiring it...

baseDir = Sketchup.find_support_file('Plugins')
relDir  = "examples"
title   = "Choose a Dir..."

openpath = File.join(baseDir,relDir)

my_path = UI.openpanel( title, openpath, "*." )
if my_path.nil?
  # the user cancelled the dialog
else
  my_path = File.expand_path( File.dirname(my_path) )
end

(Edited for clarity, added openpath local.)

The filetype filter does not work on PC. (Windows itself is overriding the parameters, using MRU settings in the Registry for the File Open dialog.)

Now if you are wondering if you can first set the working dir, and will the UI.openpanel go there?
Not really,.. you must make the call with the wd:

Dir.chdir('C;/')
my_path = UI.openpanel( "Choose Dir...", Dir.getwd, "*." )
if my_path.nil?
  # the user cancelled the dialog
else
  my_path = File.expand_path( File.dirname(my_path) )
end
