Field Detail

MODES

public static final java.util.Collection<java.lang.String> MODES

A list of things we can zoom to. The zoom target is given depending on the mode.

mode

private final java.lang.String mode

One of MODES. Defines what we are zooming to.

lastZoomTime

protected long lastZoomTime

Time of last zoom to bounds action

lastZoomArea

protected int lastZoomArea

Last zommed bounds

Constructor Detail

AutoScaleAction

private AutoScaleAction(java.lang.String mode,
                        boolean marker)

Constructs a new AutoScaleAction.

Parameters:

mode - The autoscale mode (one of MODES)

marker - Used only to differentiate from default constructor

AutoScaleAction

public AutoScaleAction(java.lang.String mode)

Constructs a new AutoScaleAction.

Parameters:

mode - The autoscale mode (one of MODES)

Method Detail

zoomToSelection

public static void zoomToSelection()

Zooms the current map view to the currently selected primitives. Does nothing if there either isn't a current map view or if there isn't a current data layer.

zoomTo

public static void zoomTo(java.util.Collection<OsmPrimitive> sel)

Zooms the view to display the given set of primitives.

Parameters:

sel - The primitives to zoom to, e.g. the current selection.

autoScale

public static void autoScale(java.lang.String mode)

Performs the auto scale operation of the given mode without the need to create a new action.

Parameters:

mode - One of MODES.

getModeShortcut

private static int getModeShortcut(java.lang.String mode)

autoScale

public void autoScale()

Performs this auto scale operation for the mode this action is in.

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

getFirstSelectedLayer

protected Layer getFirstSelectedLayer()

Replies the first selected layer in the layer list dialog. null, if no such layer exists, either because the layer list dialog is not yet created or because no layer is selected.

Returns:

the first selected layer in the layer list dialog

getBoundingBox

private BoundingXYVisitor getBoundingBox()

updateEnabledState

protected void updateEnabledState()

Description copied from class: JosmAction

Override in subclasses to update the enabled state of the action when something in the JOSM state changes, i.e. when a layer is removed or added. See JosmAction.updateEnabledState(Collection) to respond to changes in the collection of selected primitives. Default behavior is empty.

Overrides:

updateEnabledState in class JosmAction

See Also:

JosmAction.updateEnabledState(Collection), JosmAction.initEnabledState()

updateEnabledState

protected void updateEnabledState(java.util.Collection<? extends OsmPrimitive> selection)

Description copied from class: JosmAction

Override in subclasses to update the enabled state of the action if the collection of selected primitives changes. This method is called with the new selection.

Overrides:

updateEnabledState in class JosmAction

Parameters:

selection - the collection of selected primitives; may be empty, but not null

See Also:

JosmAction.updateEnabledState(), JosmAction.initEnabledState()

installAdapters

protected final void installAdapters()

Overrides:

installAdapters in class JosmAction
