How do you clear the contents of TreeView

[UncleGrandpa]

Suppose the treeview widget is displaying the currentdir (whatever that may be) and you wish to change to a different directory and RELOAD the treeview so it DOESN'T show the previous contents when you load the NEW directory.

rootpath = RequestDir("Select Install Folder");
ChangeDir(rootpath);
PopulateTree(folderbrowser->root, rootpath);

This kinda works but the previous contents are still displayed at the top of the widget

Any help would be much appreciated.

Call SetParent(NULL) on the treeview nodes that are parented to the root.

I am not exactly sure how to do that with the code above, all SetParent(NULL) does for me is completely blanks out the widget but won't reload the contents in the treewiew or filelist.

Thanks for the help at least it is a start, and I am learning.

You would clear the old treeview widgets before you populate it with new ones.
