How to Preserve the Scrollbar Policy

Graph2DView Scrollbar Policies

Whenever an instance of class y.view.EditMode (or one of its subclasses) gets activated as the view mode for a Graph2DView, the setting for the view's scrollbar policy is reset to its defaults (VERTICAL_SCROLLBAR_AS_NEEDED / HORIZONTAL_SCROLLBAR_AS_NEEDED). This happens, for example, when the Graph2DView's current view mode switches from NavigationMode to EditMode.

In order to preserve the scrollbar policies you have set, use

EditMode.setAdjustScrollBarPolicy(boolean) on such EditMode instances as follows:

// 'myEditMode' is of type y.view.EditMode.
myEditMode.setAdjustScrollBarPolicy(false);
