Hi Koen,

The main idea of the following widget is to show/hide/reorder columns in a WTreeView :

I am using a WVBoxLayout to hold all checkboxes, and two buttons to reorder the elements : (actions are : move up/down). When moving up/down WVBoxLayout elements on Google Chrome (latest): they disappear until the mouse is moved over the layout....

My WTreeView is connected to a model of type : dbo::QueryModel< dbo::ptr >();

My model does not react on ::removeColumns(....)

Hey,

I could not reproduce the slowness --- see attached test case. Can you modify it so that it reproduces your problem ?
