[PyQt] TreeView delegate operations

Doh!please ignore that last emailI found the problem...and it is me! For those who are using Maya and PyQt, may I offer this hard-earned pearl of wisdom?(who knows maybe somebody else will have the answer, lol) Unlike MEL,...where you can re-source the code and re-run the code to ge

[PyQt] TreeView delegate operations

Having a real problem figuring this one out, am hoping you guys can shed some light on this... In my treeview, I have decoration turned off, so it looks like a table or spreadsheet,...I have a delegate (that's been working fine) that handles the display of items in the treeview, right... Across

[PyQt] treeview model/view or item-based?
