public class JGoOverviewRectangle

extends JGoRectangle

implements JGoViewListener, java.awt.event.ComponentListener

The rectangle shown and dragged around in the overview window.

This class also takes up the additional responsibilities of keeping track of changes to the view, by being both a JGoViewListener and a ComponentListener.

Constructor Detail

JGoOverviewRectangle

public JGoOverviewRectangle()

JGoOverviewRectangle

public JGoOverviewRectangle(java.awt.Point p,
                            java.awt.Dimension d)

Construct a non-resizable rectangle with an extra-wide pen, so that it can show up reasonably at the reduced scale.

Method Detail

updateRectFromView

public void updateRectFromView()

Make this JGoRectangle's position and size correspond to the observed view's position and size in the document.

setBoundingRect

public void setBoundingRect(int left,
                            int top,
                            int width,
                            int height)

Keep this rectangle within the bounds of the document. Don't let this rectangle go to negative positions if the observed view doesn't allow it.

Overrides:

setBoundingRect in class JGoObject

Parameters:

left - the left side of the new bounding box

top - the top side of the new bounding box

width - the width of the new bounding box

height - the height of the new bounding box

geometryChange

protected void geometryChange(java.awt.Rectangle prevRect)

Handle any change in location (due to dragging) of this rectangle by changing the observed view's viewPosition. Ignore any change caused by a change in the observed view.

Overrides:

geometryChange in class JGoObject

gainedSelection

protected void gainedSelection(JGoSelection selection)

Selecting the overview rectangle shouldn't show any handles or do anything else.
