Method Summary

protected void	dragSelect(Rectangle zoomselect, int ignore) This method now converts the selected screen rectangle into viewport coordinates to allow retracing.
void	init() Initializes the zoom cursor.
void	mouseClicked(MouseEvent me) Clicking with the mouse selects only a single object, the one that is closest to the mouse-click point.
void	setComposedProperties(PropertySupplying prop) Compose with a PropertySupplying as we need subclassing Cursor.

SelectCursor

public SelectCursor(PropertySupplying prop)

Creates a new zoom cursor. Dragging is always enabled, even if overruled in properties.

Method Detail

setComposedProperties

public void setComposedProperties(PropertySupplying prop)

Compose with a PropertySupplying as we need subclassing Cursor.

Specified by:

setComposedProperties in interface PropertyAware

Overrides:

setComposedProperties in class DragCursor

init

public void init()

Initializes the zoom cursor. Here, the pop-up menu and the undo-zoom list is generated.

Specified by:

init in interface Initializable

Overrides:

init in class CanvasCursor

mouseClicked

public void mouseClicked(MouseEvent me)

Clicking with the mouse selects only a single object, the one that is closest to the mouse-click point.

dragSelect

protected void dragSelect(Rectangle zoomselect,
                          int ignore)

This method now converts the selected screen rectangle into viewport coordinates to allow retracing. We store the normalized zoom in the zoom list

Specified by:

dragSelect in class DragCursor

Parameters:

zoomselect - The on-screen Rectangle of the drag, not normalized.

ignore - The extended modifiers of the mouse event on drag end.
