Well I found a solution and thought I would share it... Probably not the most elegant, but it does work..
Works by using an import global variable (told you it wasn't elegant ;-) I created a file named "ms.py" and inside is a single line: MyTreeView and that's all. In my main.py,...I "import ms" at the top. Later, I set the variable by... ms.MyTreeView = self.treeView Then in my delegate file, delegate.py, I also add "import ms" at the top. And then later, in the setModelData() function, after checking selectionMode() to make sure it's in multiSelect,...and after handling the "main" selection,I do a indices = ms.MyTreeView.selectedIndexes() and loop thru them setting their value to the value of the main selection... A side note,...when a treeView's selectionMode is set to 3 (Extended Selection), one can pull a vertical pick from top to bottom, highlighting multiple items in a single column. Then, while holding down CTRL, you can double-click selection one item out of this group. This will pass this CTRL-selection to the delegate and remove its index from the "indices" returned above. Which is good, so you don't double-set it's value. When you hit "enter", the code will take the value of the CTRL-selection and apply it to all the others who are still highlighted, making a nice clean sweep and saving lots of keystrokes if you need to change a lot of items.
