I'll have a look at that, I suppose it would then output a datatree of all the files in that folder that match some naming pattern?

Hmm I had not consider the output like that.

I was thinking more that it just outputs the string of the directory location only to a folder level.

 

Currently: D:\ Folder level 1\Folder level 2\Folder level n\File Selected

New Option addtional option: D:\ Folder level 1\Folder level 2\Folder level n\Folder Selected.

Has anyone found a way to do this? I am exporting files and need to set a folder to export to. Currently I have to copy a path and paste it into panel. Not very user friendly. It would be so much better to just pick a folder.

Than we could even use Human's "directory contents" component to list the files if necessary.

Is there a way to script something that invokes the systems folder selection dialog box and can then pass the selected folder?

I just noticed that Human UI has a "file picker" component, which can be switched between "open file", "save file" and "browse folder" mode, so at least its possible.

But even though Human UI is awesome, its not a viable option for what I am using it for. I guess we just need another param component for "folder path", rather than just "file path".

Hi Tom,

thank you, but not quite. I am looking for a way to actually select a folder using the Windows dialog. Just like you can right-click on a file path component and select "set one file path". It opens the dialog and you can pick a file. What you cant do is select a folder, which is what I am after. I dont need to get the actual contents of the folder. I am writing stuff into that folder, so mostly the folder will be empty.

Ok, I almost got it using a snippet of C# I found online. Only problem I have is how to make the directory output stick. Right now it only shows when the button is pressed.

Sorry, my C# skills are like zero.

private void RunScript(bool select, ref object dir)
{

try
{
string startupPath = Application.StartupPath;
string folder = "";
if (select == true) {
using (FolderBrowserDialog dialog = new FolderBrowserDialog())
{
dialog.Description = "Open a folder ";
dialog.ShowNewFolderButton = true;
dialog.RootFolder = Environment.SpecialFolder.MyComputer;
if(dialog.ShowDialog() == DialogResult.OK)
{
folder = dialog.SelectedPath;
}
}
}

dir = folder;
}
catch (Exception)
{
MessageBox.Show("Folder selection failed!");
}

}

Can you help with that?

Does this work for you, Just drop it into python component and change the output

import rhinoscriptsyntax as rs
F = rs.BrowseForFolder()

Yes, that works too. But how can I trigger it with a button? Sorry, my Python skills are also quite close to 0 ;)

Here are both versions so far, both with the same problem of getting the directory output to stick.

We are so close to a good solution for this. Can someone with knowledge of Python or C# please have a look and make it work with a button. Right now it only works with a toggle, which is not good.

Thanks!

Hi Armin, in the attached GHPython example the Dir output will stick. That said, I'm sure there a better (i.e. Grasshoppery ways of going about this). Anywho, see if it fits your needs :)

Thanks, Anders.

Now its working just like I would like it to work! So much better than copy/pasting folder paths into a panel :)

Do you know if there is a rhinoscript equivalent for the file selection dialog? I always find that the right-click, set one file path, is really not very nice for someone else using the script. Its kind of hidden.

UPDATE:

Ok, I figured it out. you just use the command:

rs.OpenFileName()

instead. But weirdly when doing that you select a file, you then get the weird "no-more-clicking" bug in GH. Then you press the button again, select a new file, and then it works fine!?

Also when you press Cancel it doesnt keep the path you had before, but goes back to <Null>.
