The Stop List is a list of widgets which you do not want to appear in your visu palette. Any stopped widget will still be read in correctly from your design save files, but it cannot be selected within the visu hierarchy, nor can an instance of the widget be created interactively.
For example, you can use this feature if you want to prevent use of the Paned Window widget if for some reason it is not in your company style guide.
To "stop" a widget, simply click on the appropriate toggle within the visu_config Edit Stop List dialog, then press "Apply".
You can also stop widgets through use of the visu resource visu.stopList. This is fully described in the Configuration chapter of your user guide.
Note that widgets stopped using visu_config can only be reactivated by rebuilding visu with the stop toggles reset; the visu.stopList resource can however be changed between invocations of the tool.
