BrowseForFolder method in Python might have a problem


It seems to me that the title doesn’t work. Take a look at this:

import rhinoscriptsyntax as rs
strFolder = rs.BrowseForFolder(“C:”,“Select a folder”,“Title is broken”)

The title always is “Browse for Folder” regardless of what is entered in the third argument.



Rs.BrowseForFolder method doesn't change the Title

Yeah, looks like this is the case, I don’t see a line where the title is set in the code below…

def BrowseForFolder(folder=None, message=None, title=None):
    """Display browse-for-folder dialog allowing the user to select a folder
      folder[opt] = a default folder
      message[opt] = a prompt or message
      title[opt] = a dialog box title
      selected folder
      None on error
    dlg = System.Windows.Forms.FolderBrowserDialog()
    if folder:
        if not isinstance(folder, str): folder = str(folder)
        dlg.SelectedPath = folder
    if message:
        if not isinstance(message, str): message = str(message)
        dlg.Description = message
    if dlg.ShowDialog()==System.Windows.Forms.DialogResult.OK:
        return dlg.SelectedPath

However, in looking at Windows Forms FolderBrowserDialog Class, I don’t see a title property to set, so I don’t know how you would do that…


(Dale Fugier) #3

I’ve added this to the Rhino.Python pile.


on mac, there are some problems with the command as well.

Can’t give the dialog a custom title, message, or set a default location… i get this error when trying any of those:

Message: Object reference not set to an instance of an object

another thing is i can’t exit the script if pressing the Cancel button in the dialog whereas i can in similar functions such as rs.OpenFileName()

for example, this script will return whichever folder is highlighted in the dialog regardless of pressing Cancel or Open:

import rhinoscriptsyntax as rs

def foldername():

    folder = rs.BrowseForFolder()
    if not folder:

    print folder


other than that stuff… it works great :smile:
