I thought it might be the layout too but the following createPartControl()
method in my View doesn't seem to have any effect.
/**
* This is a callback that will allow us to create
* the viewer and initialize it.
*/
public void createPartControl(Composite parent) {
GridLayout gridLayout = new GridLayout();
gridLayout.horizontalSpacing = 0;
gridLayout.verticalSpacing = 0;
gridLayout.marginWidth = 0;
gridLayout.marginHeight = 0;
parent.setLayout(gridLayout);
}
It seems as though the border is part of the window.
