Hi, I'm taking a look at the FileDialogWindow: FileDialogWindow new open.
On the left, there is a tree. With the halo, I know it is a TreeListMorph.
Here is my question:
How can I know what is happening when I click on one of the little arrows which
are just on the left of a directory name? With my changes, the subtree is very
slow to be displayed and I don't understand what is called.
Adrien.
